How Much Weight Can the DJI Agras T55 Carry? Spray, Spread, and Lift Payloads Explained

September 2, 2026

DJI Agras T55: Three Payloads, Not One “T55 Weight Capacity”

The DJI Agras T55 does not have one universal cargo number. It has three published operating payloads tied to three different mission systems:

Spraying: 50 kg operating payload in a 50 L liquid tank.
Spreading: 55 kg operating payload in an 80 L DS80L hopper.
Lifting: 40 kg operating payload with the DL100 suspended-load system.

Those values cannot be exchanged. An 80 L spreader does not carry 80 kg merely because its volume is 80 L. A 50 L spray tank does not prove that every liquid mixture weighs exactly 50 kg. A 40 kg lifting limit does not mean 40 kg of cargo can be added without considering the current app recommendation, rigging basis, battery, environment, cable, and aircraft configuration.

The aircraft’s own published weight also changes with battery. In the standard two-sprinkler spray configuration, T55 weighs 45 kg with the standard DB1050 battery and 48.4 kg with the optional DB1580. DJI then publishes different maximum takeoff weights for spraying, spreading, and lifting with each battery.

The safest and most useful answer is therefore:

The DJI Agras T55 carries up to 50 kg for spraying, 55 kg for spreading, or 40 kg for lifting, but the DJI Agriculture app can recommend a lower load based on aircraft state, battery, environment, and operation.

That distinction matters commercially. A farmer may ask how many gallons fit in the spray tank. A fertilizer contractor may ask whether the hopper accepts a full bag. A logistics customer may ask whether the drone can move a 38 kg component. Each question uses a different payload system and a different loading method.

Ares Acres helps operators configure the complete aircraft around the load category that will generate work.

Prefer to watch first? The video presents the T55 as a 50 L sprayer, 80 L spreader, and 40 kg lifting drone. This guide goes deeper by separating volume from mass, mapping payload to battery-specific takeoff weight, explaining why the recommended load can change, and showing how to calculate practical loads.

Quick Answer: DJI Agras T55 Payload Capacity

T55 mission	Tank or system volume	Published operating payload	Critical distinction
Spraying	50 L	50 kg	Liquid volume and liquid mass are separate
Spreading	80 L	55 kg	Low-density material may fill volume first
Lifting	Suspended cargo on 10 m standard cable	40 kg	Rigging, shape, swing, wind, and app recommendation matter

With DB1050, DJI publishes maximum takeoff weights of 95 kg for standard spraying, 99 kg for optional four-nozzle spraying, 104 kg for spreading, and 84 kg for lifting.

With DB1580, DJI publishes 99 kg for standard spraying, 103 kg for optional four-nozzle spraying, 108 kg for spreading, and 89 kg for lifting.

Maximum takeoff weight is the total aircraft configuration, battery, payload hardware, and carried load under the published framework. It is not the same as payload.

1. The Four Different “Weight” Terms

T55 content should distinguish four technical ideas:

Aircraft weight

The battery-installed aircraft in a stated payload configuration before carried material. DJI publishes 45 kg with DB1050 and 48.4 kg with DB1580 for standard spraying.

Tank or hopper volume

Space available for material, measured in liters. T55 has a 50 L spray tank and 80 L spread hopper. Liters are not kilograms.

Operating payload

The published mass of liquid, granules, or cargo carried in the mission system: 50 kg spray, 55 kg spread, or 40 kg lift.

Maximum takeoff weight

The total permitted published mass of aircraft, battery, installed payload hardware, and carried load for the stated configuration and conditions. T55 has several values, not one.

Confusing these terms creates bad purchase expectations and unsafe load assumptions. The most common error is reading “80 L spreader” as “80 kg fertilizer.” The correct published mass is 55 kg.

2. Why the T55 Has Three Different Payload Capacities

Liquid spray sits inside a tank integrated close to the aircraft. Granular material sits in a hopper and moves through a feeder and disc. Lift cargo hangs beneath the aircraft on a cable and can swing.

Each payload creates a different structural, propulsion, balance, control, and safety problem. That is why the maximum mass changes by mission.

Spray liquid is contained but moves within the tank as volume decreases. The aircraft controls flow through pumps and sprinklers.

Granular material changes mass distribution as the hopper empties. Density and bridging affect the system, and the feeder and disc add payload hardware.

Suspended cargo can swing, rotate, shift, catch wind, or contact obstacles. The aircraft must control a moving pendulum below it. A lower 40 kg limit reflects a different dynamic challenge rather than a weak aircraft.

3. Spray Payload: 50 Kilograms

DJI publishes a 50 kg operating payload for the T55 spraying system. This is the maximum headline mass associated with its 50 L HDPE tank under the supported framework.

Water has a density near 1 kg/L under ordinary conditions, so 50 L of water is close to 50 kg. Agricultural mixtures can be heavier or lighter. Product concentration, dissolved solids, suspension, temperature, and formulation affect density.

If a mixture density is 1.05 kg/L, 50 L would weigh approximately 52.5 kg. The 50 L tank has physical volume, but the 50 kg operating payload remains the mass consideration. The operator may need less than 50 L to stay within the supported load.

If a mixture density is 0.98 kg/L, 50 L would weigh approximately 49 kg. Volume would become the limit first.

The correct loading method follows current DJI and product instructions. Do not estimate payload by tank appearance when density differs meaningfully from water.

4. Liquid Density Calculation

Payload mass equals liquid volume multiplied by liquid density:

Mass in kg = volume in L × density in kg/L.

Examples:

Loaded volume	Mixture density	Calculated liquid mass
50 L	1.00 kg/L	50.0 kg
50 L	1.03 kg/L	51.5 kg
48 L	1.03 kg/L	49.44 kg
50 L	0.98 kg/L	49.0 kg
45 L	1.08 kg/L	48.6 kg

These examples demonstrate why 50 L and 50 kg are separate specifications. They do not prescribe a mixture or load. Use verified product density and the aircraft’s current recommended value.

The ground station should measure liquid accurately. Calibrated tanks, scales, meters, and repeatable transfer are more reliable than estimating from a partial container.

5. Spray Tank Volume: 50 Liters

Fifty liters equals approximately 13.21 U.S. gallons. It represents theoretical area according to application volume:

Application rate	Theoretical area from 50 L
1 gal/acre	13.21 acres
2 gal/acre	6.60 acres
3 gal/acre	4.40 acres
4 gal/acre	3.30 acres
5 gal/acre	2.64 acres

Actual coverage can differ because of reserve, route ends, overlap, partial fills, remaining liquid, battery return, ferry distance, and field shape.

The useful payload question is not just “Can it carry 50 L?” It is “How often does 50 L complete one logical route for this business?” If most blocks use 40–48 L, T55 is well matched. If they require 70–100 L, refill strategy or a larger model should be compared.

6. Standard Versus Optional Spray Hardware

Standard spraying uses two LX09050DX centrifugal sprinklers and delivers up to 40 L/min. Optional four LX09510DX mist sprinklers raise maximum flow to 50 L/min.

Optional hardware changes the aircraft configuration and published maximum takeoff weight. With DB1050, standard spraying is published at 95 kg maximum takeoff weight and optional four-nozzle spraying at 99 kg. With DB1580, the figures are 99 and 103 kg.

The four-nozzle number is higher because the configuration itself includes additional hardware. It does not mean the operator may add four extra kilograms of liquid beyond the 50 kg spray operating payload.

Payload and flow must remain separate. Fifty kilograms describes carried liquid mass. Fifty liters per minute describes optional delivery capacity.

7. DB1050 Standard-Spray Weight Equation

In the standard configuration:

published aircraft weight with DB1050: 45 kg;
published spray operating payload: 50 kg; and
published maximum spraying takeoff weight: 95 kg.

The arithmetic aligns: 45 + 50 = 95 kg.

This does not authorize the pilot to ignore the app recommendation. It shows how the standard specification is constructed under the listed condition.

The DB1050 weighs 8.3 kg and has 20 Ah capacity. Its lower mass supports T55 handling and can be sufficient when a 50 L payload empties before a larger battery is needed.

8. DB1580 Standard-Spray Weight Equation

With DB1580:

published aircraft weight: 48.4 kg;
published operating payload: 50 kg; and
published maximum standard spraying takeoff weight: 99 kg.

The published maximum is rounded relative to simple arithmetic. Treat DJI’s table, not a homemade sum, as authoritative.

DB1580 weighs 11.7 kg and has 30 Ah capacity. It adds 3.4 kg and more endurance. It is useful when low application rate, ferry, altitude, or route duration makes battery energy limiting.

The larger battery does not increase the published spray payload above 50 kg. It increases system energy and total takeoff weight.

DJI states that the Agriculture app can recommend loading based on current aircraft status, environmental conditions, and operational task.

Reasons can include:

elevation and lower air density;
high temperature;
wind and turbulence;
battery model, temperature, health, or state;
optional hardware;
route climb or terrain;
aircraft condition;
lift cargo behavior;
mission speed and maneuvering; and
safety margin for the actual work.

A maximum is the outside of the published envelope. A recommended load is the current operational instruction. The recommended value wins.

10. Spreading Payload: 55 Kilograms

The DS80L spreader carries a published 55 kg operating payload. It adds 5 kg over T55’s liquid-payload mass and 5 kg over T50’s spreading payload.

Granular loads should be weighed. A bag label provides nominal net mass, but partial bags, moisture, packaging, residue, and handling can change what enters the hopper.

The spreader’s weighing system and payload indicator help monitor material in real time. Ground scales and inventory records provide an independent loading basis.

Fifty-five kilograms is the mass limit. Eighty liters is the space available. The material that reaches either limit first determines the practical load.

11. Spreader Volume: 80 Liters

Bulk density determines how much mass fits into 80 L:

Mass in kg = hopper volume in L × bulk density in kg/L.

Material bulk density example	Mass if 80 L were completely filled
0.30 kg/L	24 kg
0.50 kg/L	40 kg
0.6875 kg/L	55 kg
0.80 kg/L	64 kg
1.00 kg/L	80 kg

If bulk density exceeds 0.6875 kg/L, a full 80 L would exceed 55 kg. Mass becomes the limit before volume.

If bulk density is below 0.6875 kg/L, volume can fill before the material reaches 55 kg. Low-density seed is a common reason hopper liters matter independently of payload kilograms.

The table is mathematical illustration, not material authorization. Use actual bulk density, supported feeder, current load recommendation, and the manufacturer’s operating procedure.

12. Why a “Full Bag” Can Fit but Must Still Be Weighed

The supplied video states that T55 can carry a full bag of fertilizer in a single flight. That is a useful handling concept because many common bag sizes fall within 55 kg.

Bag sizes vary by market and material. A “full bag” is not a technical unit. One supplier may package 25 kg, another 40 kg, 50 kg, or another amount.

The hopper may accept the bag by volume, but the net material plus residual contents must stay within the current load recommendation. Wet or clumped fertilizer can also change flow and bulk density.

Publish the precise specification first: 80 L and 55 kg. Use “full bag” as an illustrative benefit only when the actual package is confirmed.

13. Spreading Rate Is Not Payload

T55 publishes up to 400 kg/min maximum discharge under a compound-fertilizer test condition. That number describes how fast the feeder system can release material, not how much the hopper holds.

The hopper holds 55 kg by mass. At the theoretical maximum, it would empty in less than nine seconds. Actual field operation uses much lower delivery based on target rate, speed, width, feeder, and material.

Confusing payload and flow creates the impossible claim that T55 “carries 400 kg.” It does not. It can carry 55 kg and the system has a 400 kg/min maximum discharge ceiling under stated conditions.

14. Spreading Area per 55-Kilogram Load

Theoretical area equals load mass divided by target rate:

Target rate	Theoretical area from 55 kg
25 kg/ha	2.20 ha
50 kg/ha	1.10 ha
75 kg/ha	0.733 ha
100 kg/ha	0.55 ha
150 kg/ha	0.367 ha
200 kg/ha	0.275 ha

Actual area depends on measured load, residual material, route, width, overlap, turn behavior, feeder, disc, and uniformity.

The table helps plan reloads. It does not select the rate; agronomic and product requirements do.

15. Feeder Selection and Payload Use

T55 provides five feeder choices across standard and optional configurations. They cover approximately 0.5–10 mm material sizes across the range.

The feeder affects how consistently the 55 kg load can be delivered. A feeder intended for large fertilizer may not meter small seed precisely. A feeder intended for fine material may not accept large granules.

Payload capacity has value only when the material flows. Bridging, moisture, irregular particles, damage, dust, and feeder mismatch can leave material in the hopper and reduce usable load.

Templates and automatic calibration reduce repetitive setup, but current material should be verified.

16. Lifting Payload: 40 Kilograms

The DL100 lifting system has a 40 kg published operating payload. It supports automatic functions, Auto Balance Control, cargo obstacle avoidance, and emergency cable release.

Lift payload is dynamically different from tank payload. Cargo can swing, rotate, shift, catch wind, contact obstacles, or change the aircraft’s center-of-mass relationship.

The 40 kg maximum should never be exceeded to “see whether it can.” DJI recommends flying within the app’s current recommended payload so the aircraft can better handle swing and climbing overload.

Overload can cause severe vibration, failure to stabilize, loss of balance control, or loss of aircraft control.

17. Does Rigging Count Toward Lift Weight?

DJI’s related current-platform specifications describe lift capacity as including applicable rope and hook weight. The operator should treat the complete suspended system—not only the useful cargo—as part of load planning and follow the T55 manual’s current wording.

If cargo weighs 38 kg and additional rigging contributes 2 kg under the applicable basis, the complete load is at the 40 kg published class before any lower app recommendation.

Use a verified scale. Do not trust shipping labels or visual estimation for a near-limit lift.

The business should create standard rigging kits with known weight and inspection records. Subtract their applicable weight before deciding how much useful cargo can be carried.

18. Load Shape Can Matter More Than Mass

A compact 30 kg bag and a broad 20 kg panel are not equivalent. The panel can catch much more wind, rotate, and swing.

DJI advises against large wind-facing cargo. Aerodynamic force increases with area and wind speed. Irregular loads can also shift their center of gravity.

The route, climb, turn, and descent should be conservative. Load testing should begin below maximum with the actual rigging and shape in a controlled area.

Auto Balance supports the aircraft; it does not correct a load that is inadequately contained, improperly attached, or aerodynamically unsuitable.

19. Lift Cable Length and Payload Behavior

T55 includes a 10 m standard lift cable and DJI recommends 10–15 m.

A cable that is too short can allow swinging cargo to approach the propellers. A cable that is too long can allow cargo or cable to touch the ground, trees, wires, or other obstacles.

Longer cable also changes pendulum behavior and the vertical space required at pickup and destination. Shorter cable changes aircraft-cargo separation.

Select cable length for the route and load, not simply the largest available distance.

20. Auto Balance Control

Auto Balance Control helps manage suspended cargo behavior. It can reduce pilot workload and stabilize supported loads.

The feature does not increase the 40 kg payload limit. It does not make strong wind, improper rigging, moving contents, or excessive swing acceptable.

The operator should monitor load behavior from pickup through landing or release. If swing grows, the correct response may be to slow, stop, descend to a safe area, or use the supported emergency procedure.

21. Cargo Obstacle Avoidance

Cargo obstacle avoidance considers the suspended-load operation, but the cable and cargo occupy space below the aircraft that normal airframe clearance does not describe completely.

The route must provide clearance for aircraft, cable, and cargo. A tree branch below the aircraft can catch the line. A power line can intersect the cable even if the aircraft passes above.

Map the full vertical corridor. Use conservative height and destination approach. Do not assume aircraft sensors can see every cable-level hazard.

22. Emergency Cable Release

The emergency cable-release function can separate cargo when retaining it threatens aircraft control. It is a last-resort safety tool, not a routine unloading method unless the supported operation specifies otherwise.

Release changes the risk from an unstable aircraft to a falling load. The route should avoid people, vehicles, livestock, buildings, roads, water users, and sensitive areas beneath it.

Pilots and ground crew should understand activation, consequences, and post-event inspection before a live lift.

23. DB1050 Versus DB1580 for Lifting

With DB1050, DJI publishes an 84 kg maximum lifting takeoff weight. With DB1580, it publishes 89 kg.

The larger battery increases aircraft and system mass while adding energy. The lift payload remains published at 40 kg rather than increasing with DB1580.

Battery choice should consider route duration, climb, altitude, temperature, return reserve, and the app’s recommendation. A short 15 kg lift may favor the lighter pack. A longer route may benefit from DB1580.

The aircraft’s total response to swing and wind matters more than nominal amp-hours alone.

24. Altitude and Payload

Air density decreases with altitude. Lower density reduces the thrust produced for a given rotor condition and can increase power demand. DJI’s app can therefore recommend less payload in high-altitude work.

DB1580 may provide more energy for certain high-altitude or long-duration scenarios, but more battery also adds mass. It does not override the app’s load value.

A buyer serving high-elevation farms should evaluate the actual site, temperature, expected payload, route climb, and battery plan before treating sea-level maximums as routine.

Record recommended loads and landing state across representative fields. Local evidence should inform quotes, schedules, and fleet sizing.

25. Temperature and Payload

High temperature affects air density, motors, electronics, batteries, charging, cooling, product behavior, and people. The aircraft may have less performance margin, while batteries may land warmer.

Low temperature affects battery performance, liquid behavior, and the aircraft’s operating range. DJI publishes 0–40 °C for T55 aircraft operation.

The correct payload can therefore change seasonally. A load that is appropriate on a mild morning should not be assumed appropriate on the hottest afternoon.

T55’s onboard heat sink and ground air cooling help thermal cycle time. They do not raise the payload limit or make environmental assessment unnecessary.

26. Wind and Payload

Wind creates flight demand for all payloads. For spraying, it also affects droplet movement and application suitability. For spreading, it affects granular distribution. For lifting, it affects cargo swing and windward force.

Maximum aircraft wind resistance is published at 6 m/s, but the mission limit can be lower. Product directions, drift control, material, cargo shape, route, gusts, and site hazards matter.

A 40 kg compact lift may remain more predictable than a 15 kg broad load. Payload mass alone cannot describe wind response.

Do not add payload to “stabilize” the aircraft in wind. The correct response is to operate within current mission and environmental limits.

27. Terrain and Climb

Climbing with payload requires power. Steep terrain, elevation change, obstacle bypass, and connection routes can reduce useful endurance and load margin.

Radar and terrain-following support the route, but the pilot should understand where the aircraft climbs with a full tank, hopper, or suspended cargo.

For spraying and spreading, a route can be designed so the heaviest portion occurs where climb demand is manageable. For lifting, the pickup and destination elevations determine the energy profile.

Test representative terrain below maximum before committing to a production load plan.

28. Battery Health and Payload

A battery’s model capacity is not the same as its current health. Age, cycles, temperature exposure, storage, events, imbalance, connectors, and maintenance affect available performance.

The app and battery records provide evidence. A pack that is no longer suitable for a high-payload route should not be kept in service merely because its label says DB1050 or DB1580.

Track every battery by identifier and aircraft assignment. Inspect contacts and locking. Retire packs according to current guidance.

Payload planning should use the battery actually installed, not the best battery in the fleet.

29. Aircraft Condition and Payload

Propeller damage, motor condition, loose hardware, pump or spreader faults, contaminated sensors, blocked cooling, arm-lock issues, and structural damage can reduce safe operation.

A maximum payload should never be used to test whether a questionable aircraft is “still strong enough.” Remove it from service and inspect.

Preflight checks protect payload capacity by ensuring the platform is in the condition on which the specification depends.

Unusual vibration, sound, smell, temperature, control behavior, or load indication deserves immediate attention.

30. Payload Indicator Light

The video highlights a payload indicator light that allows real-time monitoring of payload volume. This reduces uncertainty during loading and operation.

For spraying, liquid-level information helps the pilot understand route completion and refill timing. For spreading, weighing feedback provides granular quantity. The display should be cross-checked against measured loading and consumption.

A sensor can be misled by calibration, residue, material behavior, slope, or fault. The operator should respond to inconsistent readings rather than forcing a route based on an expected number.

31. Why Maximum Payload Is Not a Productivity Guarantee

A full load can reduce refill events, but it also increases takeoff mass, power demand, and sometimes route or handling requirements.

If a field needs only 30 L, loading 50 L adds unused weight. If a spread route needs 35 kg, loading 55 kg leaves residual material or requires a route change. If a lift needs 20 kg, adding ballast creates no revenue.

Right-sized loading can improve energy use, handling, and turnaround. The objective is to carry the material needed for the planned segment with appropriate reserve and margin—not to maximize every takeoff.

Productivity comes from completed work per full cycle, not kilograms at launch.

32. Spray Refill Mathematics

Suppose a field requires 120 L. Ignoring reserve and operational factors, T55 needs two full 50 L loads and one 20 L load.

Loading 50 L on the final route would carry 30 L that is not required. A measured partial load reduces takeoff mass and remaining-product management.

If a route requires 52 L, the field must be split or the refill point adjusted. Two flights do not mean both should carry 50 L; the second may carry only the measured remainder plus the supported operational amount.

Route segmentation should minimize connection distance and preserve application continuity.

33. Spread Refill Mathematics

A 240 kg fertilizer job divided by 55 kg equals 4.36. It requires four full 55 kg loads and a fifth partial load of 20 kg in pure arithmetic.

Actual planning includes residual material, measured transfer, rate, field boundaries, and the app’s recommendation.

If the fertilizer bulk density fills 80 L before reaching 55 kg, more loads are required. That is why both hopper volume and payload mass belong in the model.

Material tender speed also matters. A 55 kg aircraft that waits ten minutes for bags and weighing is not using its payload capacity efficiently.

34. Lift Mission Mathematics

A cargo item should be weighed with the applicable rigging basis. Suppose useful cargo is 32 kg and the applicable cable, hook, sling, or attachment adds 3 kg. The planned suspended mass is 35 kg.

That is below the 40 kg published class but may still exceed the app’s current recommendation under high elevation, heat, wind, battery condition, or route.

Multiple items in one net can shift. Their combined mass and containment must be verified. Do not calculate only the heaviest individual item.

The destination must be capable of receiving the complete load safely.

35. Center of Gravity for Tank and Hopper Loads

DJI designs the spray and spread systems to integrate with the aircraft, but correct installation and loading remain important.

An incorrectly seated tank, loose module, uneven material, blockage, or damaged mount can change mass distribution. The aircraft should not launch with an unresolved balance warning or abnormal posture.

Granular bridging can leave material concentrated on one side. The feeder and hopper should be inspected if weighing or flow behaves inconsistently.

Liquid movement is managed by the tank design, but abrupt maneuvering with a heavy load still increases demand.

36. Center of Gravity for Suspended Cargo

Suspended cargo naturally hangs below the attachment point, but the load can tilt, shift, or rotate if rigging is unbalanced.

Place attachments so the center of gravity remains predictable. Contain loose contents. Use symmetric or engineered rigging appropriate to the load.

Test pickup at low height in a controlled exclusion zone. Confirm that the cargo hangs as expected before beginning the route.

Auto Balance Control assists after proper preparation; it is not a substitute for finding the center of gravity.

37. Ground Handling and Loaded Aircraft

T55’s 45 kg standard aircraft weight supports solo transport, but a fully loaded spray configuration can reach 95 kg. The spreading configuration can reach 104 kg with DB1050 or 108 kg with DB1580 under the published maximum table.

Do not plan to lift or carry the loaded aircraft manually as if it were empty. Position the aircraft first, then load at the launch area using a controlled process.

Trailer deck, ramp, dolly, handles, tie-downs, and working height should be designed around empty-aircraft movement and safe payload loading.

Keep people clear of the aircraft when powered, loaded, or preparing to launch.

38. Liquid Loading Workflow

A disciplined spray load process can include:

verify aircraft and tank condition;
confirm product, rate, route, and required volume;
calculate mixture and density where relevant;
prepare material in the correct order;
measure the intended load;
transfer through the supported fill path;
confirm level and leaks;
confirm app recommendation and aircraft state;
secure fill points; and
record the load.

The exact process follows current product and aircraft instructions. The objective is repeatability and traceability.

39. Granular Loading Workflow

A disciplined spread load process can include:

identify material and lot;
confirm particle range and feeder;
inspect material for moisture, clumps, damage, or contamination;
determine bulk density where needed;
verify target rate and route;
weigh the load;
load without exceeding volume or mass;
confirm weighing and template;
check disc, feeder, and containment; and
record remaining inventory.

Bag count is not enough when bags are partial or nominal weights vary.

40. Lift Loading and Rigging Workflow

A disciplined lift process can include:

identify cargo, useful mass, and rigging mass;
inspect cargo integrity and windward area;
inspect cable, hook, release, and attachment;
choose cable length;
establish pickup, route, emergency, and destination zones;
establish ground communication and exclusions;
connect and test at low height;
confirm app load recommendation;
begin conservatively; and
inspect after completion.

Lift operations require dedicated training and should never be improvised from spray experience alone.

41. Comparing T55 Payload With T50

T50 carries 40 L/40 kg spray and 50 kg spread. T55 increases those figures to 50 L/50 kg spray and 55 kg spread, while adding a dedicated 40 kg lift system.

T55 therefore adds 25% spray capacity, 10% spread-payload mass, and an entirely new payload category.

It also lowers published battery-installed aircraft weight relative to T50 while using larger 62-inch propellers and current-generation batteries.

Existing T50 power and parts investment still matters. Payload improvement should be weighed against platform-transition cost.

42. Comparing T55 Payload With T70P

T70P publishes 70 L spray, 70 kg spread, and 65 kg lift. It exceeds T55 by 20 L spray, 15 kg spread, and 25 kg lift.

T55 is lighter and has higher maximum spray flow: 40/50 L/min versus T70P 30/40 L/min.

The choice is payload and endurance versus flow and handling. T70P is required for recurring 41–65 kg lift work; T55 can be more efficient when jobs fit its capacities.

Battery configuration must be verified when planning full T70P spray payload.

43. Comparing T55 Payload With T100

T100 publishes 100 L/100 kg standard spray, 150 L/100 kg spread, and 100 kg standard lift. It is in a much larger payload class.

T55 remains lighter and publishes higher maximum spray flow in standard and optional comparisons. It is easier to transport and support.

T100 is appropriate when the operation can use 100 kg loads and has the crew, tender, battery, charging, and vehicle infrastructure to keep them productive.

T55 is appropriate when 50/55/40 kg capacities fit the work and unused flagship payload would add cost and handling.

44. One T100 or Two T55 Aircraft?

Payload alone cannot answer fleet sizing. One T100 carries twice the spray liquid of one T55. Two T55 aircraft can carry the same nominal combined liquid across parallel flights, but require two pilots or supported multi-aircraft workflow, two launch cycles, and broader fleet coordination.

Two T55 aircraft provide dispatch redundancy and can serve separate small fields. One T100 reduces refill events on a single large route.

Compare total aircraft, controller, battery, ground crew, transport, support, and utilization—not only combined kilograms.

45. When 50-Kilogram Spray Capacity Is Ideal

T55 spray capacity is ideal when:

normal route liquid requirement falls near 35–50 L;
high flow matters more than tank endurance;
fields are dispersed or irregular;
one-pilot handling matters;
the ground station can refill quickly;
transport width and weight are constrained; or
T55 complements a larger fleet aircraft.

The right-sized tank reduces unused payload without making the aircraft a small tool.

46. When 55-Kilogram Spread Capacity Is Ideal

T55 spread capacity is ideal when:

common bag sizes fit under 55 kg;
route mass is 55 kg or less;
high maximum discharge is valuable;
an 80 L hopper fits material density;
multiple feeder types support the service mix;
manual loading remains manageable; or
a smaller aircraft serves seed, fertilizer, and feed work.

If material routinely needs 56–70 kg per route, T70P should enter the comparison. If routes need 100 kg, T100 should.

47. When 40-Kilogram Lift Capacity Is Ideal

T55 lift capacity is ideal when recurring cargo, with the applicable rigging basis, stays comfortably below 40 kg and the value comes from access rather than maximum mass.

Examples can include supported bags, orchard supplies, compact tools, parts, or site material. Exact suitability depends on shape, containment, route, wind, and local operating requirements.

If recurring loads exceed 40 kg, select a larger supported platform rather than splitting awkwardly or overloading.

48. Payload and Revenue

Payload creates revenue only when attached to demand. Spray capacity can reduce refills. Spread capacity can move more material. Lift capacity can create a logistics service.

The business should calculate:

jobs that fit one load;
refills removed;
time saved per cycle;
jobs previously declined;
ground labor added;
battery and power requirements;
payload-system cost;
spares and service; and
realistic annual utilization.

A 40 kg lift feature with no customers has option value, not guaranteed revenue. A 50 L tank that removes one refill on every job has immediate measurable value.

49. Payload and Insurance or Operating Records

Records should identify aircraft, battery, payload system, loaded mass or volume, material, route, date, pilot, environmental conditions, and any event.

Accurate records support maintenance, customer reporting, inventory, training, and incident review. They also reveal whether maximum capacities are actually used.

Never alter load records to match a nominal package. Record what was measured and what the app recommended.

50. Payload Preflight Checklist

Before every mission:

identify the correct payload system;
inspect installation and condition;
confirm battery model and aircraft state;
confirm environment and route;
calculate or measure load;
verify volume and mass separately;
confirm feeder, sprinkler, or rigging;
confirm app recommended load;
check containment, leaks, or security;
confirm people and site controls;
verify emergency plan; and
record the mission.

The checklist should be aircraft-specific and current.

51. Full-Set Buying Checklist for Payload Work

Confirm whether the quoted package includes:

standard 50 L spray system;
optional four-mist hardware if 50 L/min is required;
DS80L spreader;
standard and required optional feeders;
DL100 lift system, cable, hook, and supported release hardware;
correct battery model and count;
generator or charger and cooling;
controller and payload-display functionality;
relay and RTK if the route needs them;
scales, measuring, loading, and cleaning support;
critical payload spares;
setup, calibration, training, and delivery; and
current support and warranty process.

An aircraft-only purchase cannot perform every advertised payload mission without the corresponding modules.

52. The Most Important Payload Rule

Use the lower of the current app recommendation and the applicable published or documented limit. Never load by tank volume alone, never use a maximum as a target, and never transfer a limit from another payload mode.

The three numbers should remain visible in every customer conversation:

50 kg spray. 55 kg spread. 40 kg lift.

That clarity protects the aircraft, the job, and the buyer’s expectation.

53. Eight Payload Planning Examples

Example 1: Forty-five liters of water-based mixture

At approximately 1 kg/L, the liquid mass is close to 45 kg. The load is below the 50 L tank volume and 50 kg operating payload. The app’s current recommendation and complete mission still control.

Example 2: Fifty liters of a dense mixture

At 1.04 kg/L, 50 L calculates to 52 kg. Tank volume fits, but mass exceeds the 50 kg published operating payload. The operator must use the current supported loading process and reduce volume as required.

Example 3: Fifty kilograms of dense fertilizer

If bulk density is 0.90 kg/L, 50 kg occupies about 55.6 L. It fits the 80 L hopper and remains below 55 kg, assuming the material and feeder are supported.

Example 4: Fifty-five kilograms of low-density seed

At 0.50 kg/L, 55 kg would require 110 L. The 80 L hopper fills before the mass limit. Practical payload would be about 40 kg at that simplified density.

Example 5: One 50 kg fertilizer bag

A verified 50 kg net bag can fit below the 55 kg spread-payload maximum if hopper volume, recommended load, material condition, and feeder support align. Residual material and partial prior contents must be counted.

Example 6: Thirty-seven-kilogram cargo with rigging

If the applicable rigging adds 2.5 kg, the planned suspended mass is 39.5 kg. It is near the published 40 kg class and leaves little room for measurement error or a lower app recommendation. A controlled lower load or larger platform may be more appropriate.

Example 7: Twenty-kilogram broad cargo

Mass is only half the lift maximum, but a broad wind-facing surface can make it unsuitable. Shape, route, and wind can control the decision before weight.

Example 8: Fifty-liter spray route at high elevation

The tank and operating-payload numbers do not change on the product page, but the app may recommend a lower load because of air density, temperature, battery, and route. The current recommendation is the actionable number.

54. Selecting a Scale and Measurement Method

Liquid volume can be measured by a calibrated mix tank, transfer meter, marked container, or supported aircraft indication. Liquid mass can be verified with density and volume or direct weighing where the workflow supports it.

Granular material should be weighed with a scale appropriate to 55 kg-class loading. The scale should be placed on a stable surface, checked with known mass, protected from contamination, and used consistently.

Lift cargo needs a scale that includes the complete applicable suspended setup. A handheld estimate or supplier description is not sufficient near 40 kg.

Measurement equipment should be part of the full set. A payload specification without a method to verify the payload is operationally incomplete.

55. Partial Loads Are a Professional Tool

Loading less than maximum is not wasted capacity. A partial load can match a field segment, reduce remaining product, lower takeoff mass, shorten fill time, improve energy use, and keep the route inside a current recommendation.

A 22 L final spray load can be more efficient than carrying 50 L for a field that needs only 22 L. A 20 kg final fertilizer load can close the job without returning with excess material. A 15 kg cargo task should remain a 15 kg task.

Templates and records can standardize partial loading so the ground team does not treat every departure as “fill it.”

56. Payload Changeover

T55 can switch among spray, spread, and lift systems, but payload change is a controlled configuration event.

Before installation, clean the aircraft and module, inspect mounts and connectors, confirm firmware or app recognition, secure every latch or fastener, and verify the correct maximum takeoff framework.

After installation, perform supported functional checks. A spreader should report load and feeder status. A spray system should be leak-free and deliver correctly. A lift system should respond correctly before cargo is attached.

Store removed modules where residue, impact, weather, and electrical contamination will not damage them.

57. Payload Contamination and Weight

Residue has operational consequences beyond cleanliness. Liquid trapped in hoses or tank, fertilizer left in the hopper or structure, and mud on the aircraft add mass and can distort load indication.

Residual material can also react with the next product, corrode components, obstruct feeders, block filters, contaminate sensors, or alter balance.

The payload should begin from a known clean or appropriately prepared state. If product remains intentionally for the next route, it belongs in the load calculation and record.

58. Payload Training for Pilots and Ground Crew

Pilots need more than aircraft-control training. They should understand mass versus volume, density, bulk density, feeder selection, lift rigging, battery effects, environmental derating, app recommendations, payload warnings, emergency release, and recordkeeping.

Ground crew should understand the same limits because they physically create the load. A pilot cannot correct an unmeasured fertilizer hopper or mislabeled cargo after takeoff.

Use scenario training: dense liquid, low-density seed, partial bag, near-limit cargo, hot battery, high-elevation field, abnormal scale reading, and route change. Practicing decisions is more valuable than memorizing three numbers without context.

59. What to Do After a Payload Event

An overload warning, leak, spill, feeder jam, dropped material, hard landing, cargo swing, emergency release, propeller contact, or abnormal vibration should stop routine dispatch.

Secure the area, preserve logs, document the load and conditions, inspect the aircraft and payload system, and follow current DJI service guidance. Do not simply reduce the next load and assume the aircraft is undamaged.

Battery, propulsion, arm, mount, tank, spreader, cable, hook, sensors, and structure may all require attention depending on the event.

The record should identify whether the cause was measurement, material, rigging, environment, route, hardware, training, or another factor so the procedure can improve.

60. Payload Decision Tree

Ask these questions in order:

Is the mission spraying, spreading, or lifting?
Is the correct payload module installed and inspected?
What is the material or cargo volume, mass, density, shape, and condition?
What is the applicable published payload for that mission?
What does the app currently recommend?
Does battery, temperature, altitude, wind, terrain, or route reduce suitability?
Does the sprinkler, feeder, or rigging match?
Can the ground station measure, load, recover, and record it?
Does the route protect people, property, crop, and environment?
Is a partial load or larger aircraft the better choice?

If any answer is unknown, resolve it before launch. Payload discipline begins by refusing to turn uncertainty into kilograms.

61. Building a Payload Manifest

A payload manifest gives the pilot and ground crew one shared source of truth. It can be simple enough for field use while still capturing the variables that change aircraft loading.

For spraying, record:

field and route segment;
product or mixture identifier;
target application volume;
measured load volume;
verified or calculated density where relevant;
calculated liquid mass;
sprinkler configuration;
battery model;
app recommended load;
launch and remaining volume; and
pilot and timestamp.

For spreading, record:

material and supplier or lot;
particle range;
selected feeder;
bulk density where useful;
measured load mass;
estimated occupied volume;
target rate and width;
battery model;
app recommendation;
residual mass; and
pilot and timestamp.

For lifting, record:

cargo description;
measured useful cargo mass;
applicable cable, hook, sling, or rigging mass;
complete planned suspended mass;
load dimensions and windward area;
cable length;
pickup and destination;
route and emergency area;
battery and app recommendation;
ground team; and
pilot and timestamp.

The manifest does not need to delay production. Reusable templates, material profiles, standard rigging kits, and controller records can prefill stable information. The measured values still need confirmation for the current job.

Manifests reveal patterns. They show whether the aircraft frequently leaves with partial loads, whether one fertilizer’s bulk density fills the hopper early, whether DB1580 is assigned only to routes that need it, and whether lift customers regularly approach the 40 kg class.

They also protect continuity when pilots or ground crew change. A new team member does not have to rely on “we usually fill it about here.”

62. Payload Cycle Time and Ground Labor

More payload can reduce flight cycles while increasing ground work per cycle. T55’s three systems illustrate the tradeoff.

A 50 L spray load requires water, product measurement, mixing, transfer, and rinse management. High 40–50 L/min capability can return the aircraft quickly, so the next load may need to be prepared in parallel.

A 55 kg granular load requires bags or bulk tender, weighing, lifting or transfer, feeder verification, and dust control. The aircraft can discharge rapidly, but material handling may become the bottleneck.

A 40 kg lift load can require more time to inspect, weigh, rig, connect, establish exclusions, communicate, and recover than the actual flight. That ground time is essential production work, not inefficiency to skip.

Measure complete cycle time by category:

ready aircraft to loading complete;
loading complete to takeoff;
takeoff to mission complete;
landing to payload recovery;
battery exchange and inspection;
returned battery cooling and charging; and
ready state for the next cycle.

If T55 waits on a ground task, the answer may be better staging, another scale, faster controlled transfer, parallel battery cooling, preassembled rigging, or an additional trained person—not a heavier payload.

63. Payload Utilization as a Fleet-Sizing Metric

Payload utilization equals actual carried mass or volume divided by the applicable supported planning value. It should be calculated separately for spray, spread, and lift.

A T55 averaging 46 L per spray route has 92% tank-volume utilization and is likely well matched. A T55 averaging 24 L may still be correct when blocks are small, but capacity is not the bottleneck.

A spreader averaging 52 kg per route is using most of its 55 kg mass capacity. If jobs require repeated immediate reloads, T70P or T100 deserves comparison. A spreader averaging 30 kg because low-density seed fills 80 L has high volume utilization even though mass utilization appears low.

A lift program averaging 18 kg should not be described as “underusing” T55. The drone creates value through access and speed, not percentage of maximum. A program averaging 38–40 kg deserves additional margin review and may justify a larger aircraft.

Review utilization by profitable job segment, not only fleet average. High-flow orchard spraying, broad-acre liquid work, fertilizer, seed, and lift can have different payload patterns.

64. Payload Warranty and Service Questions

Before purchase, ask how overload warnings, payload-sensor faults, tank leaks, feeder jams, weighing errors, lift cable events, emergency releases, battery events, and hard landings should be documented and serviced.

Confirm which components are consumable, which require an authorized repair process, which logs must be preserved, and which spares can be installed in the field.

Warranty should never be interpreted as permission to operate at maximum regardless of conditions. DJI’s load recommendations and current procedures remain central.

Keep proof of training, maintenance, measured loads, app warnings, and service. Good records shorten diagnosis and distinguish a hardware fault from a material, setup, or operating issue.

65. Payload Content Review Checklist

Before publishing any T55 payload article or product description, confirm that it does not:

call 80 L an 80 kg spreading payload;
call 50 L/min a payload;
call 400 kg/min a carried load;
present 40 kg lift as excluding every attachment without checking current guidance;
present a maximum takeoff weight as useful payload;
promise a full 50 L for every mixture density;
imply DB1580 raises payload;
imply obstacle avoidance makes lift routes hazard-free;
promise maximum loads at every altitude or temperature; or
describe a bare aircraft as including every payload module.

Accurate content can still be affirmative. T55 genuinely carries 50 kg spray, 55 kg spread, and 40 kg lift in an unusually light, versatile platform. Precision makes those capabilities more persuasive because the reader can trust what each number means.

66. Final Payload Selection Scenarios

If a customer needs 47 L of a near-water-density spray mixture, T55 is naturally matched by volume and mass, subject to the app and route. The correct questions are flow, field geometry, battery, refill access, and application verification.

If a customer needs 47 L of a 1.08 kg/L mixture, calculated mass is approximately 50.76 kg. The tank has room, but the published 50 kg spray payload is exceeded. The load plan must change; physical tank space is not authorization.

If a customer wants to spread a 50 kg fertilizer bag, T55 can be an excellent bag-class platform. Verify the actual net mass, bulk volume, feeder, material condition, recommended load, and route.

If a customer wants to spread 50 kg of very light seed at 0.40 kg/L, the simplified required volume is 125 L. The 80 L hopper, not the 55 kg mass rating, becomes limiting. A larger hopper or more loads should be evaluated.

If a customer needs to move a 35 kg compact part with a known 2 kg applicable rigging setup, the planned suspended mass is 37 kg. T55 may fit, but environment, battery, route, swing, and app recommendation decide whether it is suitable.

If the same 35 kg useful cargo requires 6 kg of applicable rigging, the total is 41 kg and exceeds the published lift class. The useful cargo number alone cannot be used to make it fit.

If a farm alternates 45 L spray jobs, 50 kg fertilizer jobs, and 20 kg logistics, one T55 can serve all three categories with the appropriate module changes. That is the platform’s central payload advantage: not one maximum, but three professional operating systems on one current-generation aircraft.

If a contractor regularly serves 65 L spray routes, 65 kg spreading loads, or 50 kg lift work, the T55 should not be stretched beyond its published role. T70P or T100 can add the required capacity, while T55 remains productive on the jobs it fits.

The affirmative decision is always the supported one. A right-sized T55 running measured loads will create more dependable value than an overloaded T55 chasing a larger model’s specification.

Before the first seasonal job, conduct a tabletop review with the pilot and ground crew. Give the team a dense liquid, a low-density seed, a partial fertilizer bag, a near-limit compact lift, and a light wind-facing cargo scenario. Require them to identify whether volume, mass, feeder, rigging, environment, battery, or the app becomes limiting. Then confirm where each value will be measured and recorded in the field. This short exercise exposes misunderstandings before they become a load on the aircraft.

Repeat the review whenever new material, rigging, batteries, payload hardware, firmware, personnel, or operating terrain enters the program.

A familiar aircraft can encounter an unfamiliar load, and that difference deserves a fresh calculation every time.

Measured payload discipline is the foundation of repeatable, profitable, and supportable T55 field operations.

DJI Agras T55 Payload Frequently Asked Questions

How much weight can the DJI Agras T55 carry?

Up to 50 kg for spraying, 55 kg for spreading, or 40 kg for lifting. The payload depends on the installed mission system, and the app may recommend less.

Does the T55 carry 55 kilograms in every mode?

No. Fifty-five kilograms applies only to spreading. Spray payload is 50 kg, and lift payload is 40 kg.

How many liters can T55 spray?

The spray tank holds 50 L.

How many gallons is 50 liters?

Approximately 13.21 U.S. gallons.

Does 50 liters always weigh 50 kilograms?

No. Mass equals volume multiplied by density. Water is close to 1 kg/L, but agricultural mixtures can differ.

Can I fill 50 liters of a heavy mixture?

Only if the resulting mass and current app recommendation remain within the supported load. A 1.04 kg/L mixture would weigh 52 kg at 50 L.

What is the T55 spray payload?

DJI publishes 50 kg.

What is the T55 spreading payload?

DJI publishes 55 kg in the 80 L DS80L hopper.

What is the T55 lifting payload?

DJI publishes 40 kg with the DL100 lifting system.

Does the T55 spreader hold 80 kilograms?

No. It holds 80 L by volume but carries 55 kg by mass.

Why are spreader liters and kilograms different?

Granular materials have different bulk density. A low-density seed can fill 80 L below 55 kg; dense fertilizer can reach 55 kg before 80 L.

What bulk density fills both limits together?

At a simplified calculation, 55 kg divided by 80 L equals 0.6875 kg/L.

Can T55 carry a full bag of fertilizer?

Many common bag sizes fit below 55 kg, but bag mass, material volume, residual contents, feeder, and the current recommended load must be verified.

Can T55 carry a 50-kilogram fertilizer bag?

Potentially, if the actual net material, volume, condition, feeder, aircraft, environment, and app recommendation support it.

Can T55 carry two 25-kilogram bags?

The combined 50 kg is below the published spread payload, but both bags must fit by volume after opening and the load must remain supported and correctly metered.

Can T55 carry 60 kilograms of fertilizer?

Not in the published T55 spreading payload. Sixty kilograms exceeds 55 kg. Compare T70P or another supported larger platform.

How fast can T55 discharge fertilizer?

Up to 400 kg/min under DJI’s stated compound-fertilizer test condition. That is a maximum delivery ceiling, not payload or a universal field rate.

Does 400 kilograms per minute mean T55 carries 400 kilograms?

No. It carries 55 kg for spreading. The 400 kg/min figure describes maximum system discharge under a test condition.

How many hectares can 55 kilograms cover?

Divide 55 by the target kg/ha. At 100 kg/ha, the theoretical area is 0.55 ha before route and residual effects.

Does lift rigging count toward 40 kilograms?

Treat the complete applicable suspended system, including relevant rope, hook, sling, or attachment basis, according to current DJI guidance. Do not count only useful cargo.

Can T55 lift a 40-kilogram object?

Forty kilograms is the published operating payload class, but rigging, app recommendation, altitude, temperature, wind, cargo shape, route, and battery can require less.

Can T55 lift 45 kilograms?

No. Forty-five kilograms exceeds the published 40 kg lifting payload. Use a larger supported aircraft rather than overloading.

Can T55 lift a person?

The T55 lifting system is not a passenger-transport system. Do not use an agricultural cargo drone to lift a person.

Can T55 lift a broad lightweight panel?

Mass alone is insufficient. A broad wind-facing load can swing or destabilize at well below 40 kg. DJI advises against large windward cargo.

What lift cable comes standard?

A 10 m cable.

What lift cable range is recommended?

DJI recommends 10–15 m. Too short can reduce aircraft-cargo clearance during swing; too long can contact ground obstacles or become entangled.

Does Auto Balance increase lift capacity?

No. Auto Balance Control assists cargo behavior; it does not raise the 40 kg published payload.

What does cargo obstacle avoidance protect?

It supports awareness during lifting, but the aircraft, cable, and cargo still need a fully clear route. Thin wires and cable-level obstacles require planning.

What does emergency cable release do?

It can separate an unstable or dangerous load to protect aircraft control. The route must avoid areas where a falling load would harm people or property.

How much does the T55 aircraft weigh?

DJI publishes 45 kg with DB1050 and 48.4 kg with DB1580 in standard two-sprinkler spray configuration.

Is aircraft weight the same as payload?

No. Aircraft weight describes the configured aircraft before carried material. Payload is the liquid, granules, or cargo.

What is maximum takeoff weight?

The total mass of aircraft, battery, installed mission hardware, and carried payload under the specified configuration and conditions.

What is maximum takeoff weight with DB1050?

DJI publishes 95 kg standard spraying, 99 kg optional four-nozzle spraying, 104 kg spreading, and 84 kg lifting.

What is maximum takeoff weight with DB1580?

DJI publishes 99 kg standard spraying, 103 kg optional four-nozzle spraying, 108 kg spreading, and 89 kg lifting.

Why is four-nozzle takeoff weight higher?

The optional hardware changes aircraft configuration mass. It does not increase liquid operating payload beyond 50 kg.

Does DB1580 increase spray payload?

No. The published spray operating payload remains 50 kg. DB1580 adds energy and aircraft mass.

Does DB1580 increase lift payload?

No. The published lift operating payload remains 40 kg.

Which battery is better for a full spray load?

DB1050 can be ideal when 50 L empties before battery becomes limiting. DB1580 is useful when longer, lower-rate, high-altitude, or ferry-heavy work needs more energy.

Can a damaged battery reduce payload suitability?

Yes. Battery health and condition affect performance. Use current app information, inspection, records, and retirement criteria.

Does altitude reduce the recommended payload?

It can. Lower air density increases propulsion demand, and the app may recommend a lower load.

Does hot weather reduce payload?

It can reduce performance margin and affect batteries, motors, charging, and cooling. Follow the app and current operating limits.

Does wind reduce payload suitability?

Yes. Wind affects flight, spray drift, spread distribution, and lift swing. Cargo shape can matter more than mass.

Does terrain affect payload?

Yes. Climb, slope, terrain following, obstacles, and connection routes change energy and performance demand.

Should I always fill the tank to maximum?

No. Load only what the route requires within the app recommendation. Partial loads can reduce mass, product remainder, fill time, and energy use.

Is a partial fertilizer load acceptable?

Yes when measured, correctly configured, and recorded. The target rate and route determine the needed mass.

How should spray payload be measured?

Use calibrated volume measurement and verified density where mass matters, supported tank indication, and a repeatable loading process.

How should granular payload be measured?

Use a suitable scale, the spreader weighing system, known bulk density where useful, and inventory records.

How should lift payload be measured?

Use a verified scale for cargo plus the applicable rigging basis. Never estimate a near-limit load visually.

What happens if granular material bridges?

The hopper can contain payload without delivering it correctly. Stop and address material condition, feeder, contamination, or blockage rather than forcing operation.

Does the payload indicator replace measurement?

No. It supports real-time awareness. Cross-check it with measured loading and investigate inconsistent readings.

Can residual material add to the next payload?

Yes. Liquid, fertilizer, seed, mud, or other residue adds mass and must be cleaned or included in the load assessment.

Can I move the aircraft while fully loaded?

Avoid designing a workflow that manually carries a fully loaded aircraft. Position it first and load at the controlled launch point.

What does a full standard spray T55 weigh?

The published DB1050 standard equation is 45 kg aircraft plus 50 kg spray payload, reaching 95 kg maximum takeoff weight.

Aircraft state, battery, temperature, elevation, wind, route, terrain, installed hardware, mission type, and other environmental or operational conditions.

Should the app recommendation or published maximum control?

Use the lower current applicable value. A published maximum does not override the app’s present recommendation.

How does T55 payload compare with T50?

T55 increases spray from 40 to 50 kg, spread from 50 to 55 kg, and adds a 40 kg lift system.

How does T55 payload compare with T70P?

T70P publishes 70 kg spray, 70 kg spread, and 65 kg lift. T55 is lighter and has higher maximum spray flow.

How does T55 payload compare with T100?

T100 publishes 100 kg standard spray, 100 kg spread, and 100 kg standard lift. T55 is a lighter, more deployable payload class.

Which DJI Agras should I choose for a 35-kilogram lift?

T55 may fit the published class, but include applicable rigging, app recommendation, cargo shape, environment, and route. A larger aircraft may provide more operational margin.

Which DJI Agras should I choose for a 50-kilogram lift?

T55 is not sufficient because its published lift payload is 40 kg. T70P or T100 should be evaluated.

Which DJI Agras should I choose for a 50-kilogram spread load?

T55 can fit that mass within its 55 kg spread payload if hopper volume, feeder, material, app recommendation, and conditions align.

Which DJI Agras should I choose for a 65-liter spray route?

T55 needs a planned refill or route split. T70P can hold up to 70 L in its published system and should be compared.

Which DJI Agras should I choose for a 45-liter high-flow route?

T55 can be highly suitable because the load fits 50 L and standard flow reaches 40 L/min, with an optional 50 L/min system for supported needs.

Does higher payload always mean more acres per day?

No. Flow, swath, speed, refill, battery, cooling, transport, crew, field size, route, and ground support determine full-cycle output.

What should a payload-ready T55 set include?

The correct payload modules, batteries, charging and cooling, controller, required feeders or mist sprinklers, lift hardware, measuring equipment, spares, setup, training, and support.

Is the spreader included with every T55?

Package contents vary. Confirm DS80L and the required feeders in the live full-set quote.

Is the lift system included with every T55?

Package contents vary. Confirm DL100, cable, hook, controls, training, and spares.

Is optional mist hardware included?

Not automatically. DJI identifies the four-mist configuration as optional. Confirm it when 50 L/min capability is required.

How much does a payload-ready T55 cost?

Request a live itemized quote including the mission systems, batteries, power, controller, accessories, spares, delivery, setup, training, and service.

Is T55 available in the United States?

DJI states availability is regional. Contact Ares Acres for current U.S. package status, configuration, delivery, and support.

Where can I see the T55 full set?

Final Answer: 50 Kilograms Spray, 55 Kilograms Spread, 40 Kilograms Lift

The DJI Agras T55 carries three distinct payloads:

50 kg in the 50 L spray system;
55 kg in the 80 L DS80L spreading system; and
40 kg in the DL100 lifting system.

Those figures make the T55 more than a 50 L sprayer. It is a right-sized multi-role agricultural platform capable of liquid application, bag-class granular work, and meaningful farm logistics.

The numbers remain powerful only when they are used precisely. Volume and mass must be calculated separately. Dense liquid can reach 50 kg before the tank reaches 50 L. Low-density seed can fill 80 L before the spreader reaches 55 kg. Lift cargo can remain below 40 kg yet become unsuitable because of rigging, broad shape, swing, route, or wind.

Battery changes total aircraft weight and endurance, not the three published operating payloads. DB1050 keeps the aircraft at 45 kg in standard spray configuration. DB1580 brings it to 48.4 kg and adds energy. Maximum takeoff weights change by battery and installed payload hardware, and the DJI Agriculture app can recommend a lower load for the actual environment.

The most professional loading strategy does not try to maximize every departure. It measures what the route needs, respects the current recommendation, chooses the correct sprinkler, feeder, or rigging, and records the load. Partial loads are a strength when they reduce unnecessary mass and remaining material.

Ares Acres can help configure the aircraft around the work.

Remember the payload answer:
