What Is the Biggest DJI Agras Drone?
Updated September 11, 2026.
The DJI Agras T100S is one of the largest agricultural drones DJI has ever built and is the newest flagship-generation Agras aircraft. It reaches a 149.9 kg maximum-takeoff class, uses 62-inch-class propellers, carries 85 L for spraying, 90 kg for spreading and up to 95 kg for lifting.
But if “biggest” means highest current published maximum takeoff weight or largest payload capacity worldwide, the answer needs a correction: DJI’s current global T100 specifications reach up to 175–177 kg maximum takeoff weight, with a 100 L spray tank, 150 L spreader and 100 kg lift. Therefore, the T100S is the newest large flagship, but the global T100 remains larger in several official capacity metrics.
The DJI T100S is a 149.9 kg-class flagship and one of DJI’s biggest Agras drones. It is the newest flagship generation. However, the current global DJI T100 is technically bigger by maximum published takeoff weight and several payload metrics: up to 175–177 kg MTOW, 100 L spraying, 150 L spreading and 100 kg lift. “Biggest DJI Agras” therefore depends on whether you mean newest flagship, physical footprint, MTOW, tank size or payload.

There Are Five Different Ways to Define “Biggest Drone”
Search results often use “biggest” without defining the metric. For agricultural drones, at least five measurements can produce different answers:
- Maximum takeoff weight (MTOW) — total permitted aircraft + battery + system + payload mass.
- Physical dimensions — how wide/long/tall the aircraft is when deployed.
- Spray capacity — liters or kilograms of liquid.
- Spreading capacity — hopper liters and permitted material weight.
- Lifting payload — suspended cargo capacity.
The T100S is near the top across all five, but it does not own every maximum.
DJI T100S Size and Weight
| T100S size metric | Launch-era specification |
|---|---|
| Maximum takeoff weight | Up to 149.9 kg |
| Approx. standard spray aircraft weight with battery | ~57 kg |
| Maximum diagonal wheelbase | ~2415 mm |
| Arms/propellers unfolded | ~3190 × 3570 × 934 mm |
| Arms open, propellers folded | ~1800 × 2170 × 934 mm |
| Fully folded | ~1120 × 896 × 934 mm |
| Propeller class | 62 × 23 in carbon-fiber composite |
That makes T100S a substantial commercial aircraft even when folded. The rotor footprint is measured in meters, not inches, and the support system must be designed around batteries, payload modules, refill equipment and safe crew clearance.
T100S vs T100: Which Is Physically Bigger?
The two aircraft use different geometry:
- T100S: roughly 3190 × 3570 × 934 mm fully deployed, ~2415 mm diagonal wheelbase.
- Global T100: 3220 × 3224 × 975 mm fully deployed, 2330 mm diagonal wheelbase.
T100S is wider along one dimension and has a longer diagonal wheelbase; T100 is longer in another axis and taller. Physical footprint therefore does not produce a simple “one is bigger everywhere” answer.
Maximum Takeoff Weight: T100 Wins in Global Specification
DJI’s current global T100 specification page publishes:
- 175 kg maximum spraying takeoff weight with standard two-nozzle setup,
- 177 kg with optional four-nozzle setup,
- 175 kg spreading MTOW,
- 165 kg single-battery lifting MTOW,
- 170 kg dual-battery lifting MTOW.
DJI notes a 149.9 kg limit for T100 in Australia and Turkey due to local requirements. The T100S launch configuration itself is built around the 149.9 kg class.
So if the search question is strictly “Which current DJI Agras has the highest published global MTOW?”, the current global T100—not T100S—has the larger number.
Spray Tank: T100 100 L vs T100S 85 L
The global T100 carries 100 L in its single-battery spraying configuration. T100S launch configuration carries 85 L.
T100S counters with higher flow:
- T100S: 40 L/min standard / 50 L/min optional
- T100: 30 L/min standard / 40 L/min optional
This is an excellent example of why “bigger” and “faster” are different. T100 carries more liquid; T100S can move liquid through its spray system at a higher maximum rate.
Spreading Capacity: T100 Is Larger
Global T100 publishes a 150 L spreading tank and up to 100 kg material load. T100S launch configuration uses 126 L and 90 kg. Both can reach 400 kg/min maximum discharge under specified material conditions.
If “biggest” means largest spreader, T100 currently wins.
Lifting Capacity: T100 Is Slightly Higher
T100S publishes a 95 kg lifting payload. Global T100 publishes 100 kg in its single-battery lifting configuration and 80 kg in the dual-battery configuration.
T100S’s value is not a larger raw lift number; it is the newer load-control architecture with automatic route planning, trajectory replay, three-axis load sensing, anti-sway behavior and auto weighing.
Why T100S Still Feels Like the “Biggest New DJI Drone”
Search interest around the T100S comes from three things:
- It is the newest flagship generation.
- 149.9 kg is an unusually high mass for a drone marketed around a single regulatory threshold in some regions.
- It combines spraying, spreading and heavy lifting with a new 256-line LiDAR safety system.
So the T100S is reasonably described as a massive/new flagship Agras platform, even though the global T100 has larger official capacity figures in multiple categories.
How T100S Compares With T50, T40 and T25
| Model | Spray capacity | Approx. max spray MTOW | Position |
|---|---|---|---|
| T100S | 85 L | 149.9 kg-class platform | Newest flagship generation |
| T100 global | 100 L | 175–177 kg | Largest current published payload/MTOW class in many markets |
| T50 | 40 L | 92 kg | Established large workhorse |
| T40 | 40 L | 90 kg | Earlier flagship |
| T25 | 20 L | 52 kg | Compact platform |
Why Bigger Is Not Always Better
A larger agricultural drone imposes costs:
- larger launch and landing zone,
- more trailer space,
- heavier batteries,
- more powerful charging system,
- higher water/material handling rate,
- greater regulatory complexity,
- more expensive crash or downtime exposure.
The largest aircraft makes sense when the operation can continuously feed it. If the crew cannot mix 85–100 L batches or load 90–100 kg of fertilizer quickly, the aircraft waits and its theoretical productivity disappears.
Which Farmers Benefit From a T100S-Class Drone?
- large row-crop operations,
- custom applicators paid by acre/hectare,
- orchards needing high spray flow,
- large fertilizer/seed programs,
- mountain agriculture needing cargo transport,
- operations where advanced wire/obstacle sensing reduces route-planning labor.
Which Farmers Should Choose a Smaller Agras?
T25, T50 or T55 may be a better fit when:
- fields are small or highly fragmented,
- one person handles the entire operation,
- trailer/storage space is limited,
- application rates are low,
- the operator cannot keep a flagship supplied with water/material,
- local rules make higher mass difficult to deploy.
Is the T100S the Biggest DJI Drone Outside Agriculture?
No broad “DJI drone” ranking should mix fundamentally different product categories without defining the metric. DJI also builds heavy cargo aircraft such as FlyCart platforms and enterprise aircraft with different payload purposes. This article is specifically about the DJI Agras agricultural-drone family.

Final Takeaway
The T100S deserves its reputation as a huge agricultural drone: it is a 149.9 kg-class platform with an 85 L spray tank, 90 kg spread payload and 95 kg lift. But high-quality SEO should answer the query precisely. The T100S is the newest large flagship; the current global T100 is larger by several official capacity and maximum-weight measurements. Understanding that distinction helps buyers compare the actual job each platform can perform rather than chasing a single “biggest” label.
