DJI Agras T100S vs DJI T40 — How Far Has the Flagship Platform Advanced?
Updated September 11, 2026.
The DJI Agras T40 helped establish the modern 40 L-class agricultural drone as a serious commercial application platform. The T100S shows how quickly that category has evolved. T100S more than doubles liquid capacity, multiplies maximum flow, nearly doubles spreading payload, adds a 95 kg lifting system and introduces a much denser LiDAR/radar/vision safety stack.
That does not make every T40 obsolete. T40 fleets already have batteries, generators, controllers, repair knowledge and parts inventory. For many operators, the financial question is whether the T100S’s additional throughput produces enough new acres or labor savings to justify replacing a mature operating system.
T100S is a generational leap in capacity: 85 L vs 40 L spraying, 40–50 L/min vs T40’s 12 L/min maximum pump flow, 90 kg vs 50 kg spreading payload, and 95 kg lifting versus no comparable T40 lift system. T100S also adds 256-line LiDAR, upgraded radar and new 3D mapping. T40 remains smaller, established, easier to support and may still have better economics for operators whose acreage does not require flagship throughput.

Spraying Capacity: 85 L vs 40 L
T100S carries 45 L more liquid per fill than T40. But the more dramatic difference is pump capacity. T40’s official specification gives 6 L/min × 2 pumps, or 12 L/min total. T100S is promoted at 40 L/min standard and up to 50 L/min optional.
That means T100S is not only carrying more than twice the liquid—it can discharge liquid at more than three times T40’s maximum standard hardware rate.
Why Flow Rate Matters More at High Application Rates
If an operator wants to maintain a given gallons-per-acre rate while increasing speed, pump flow must increase. T40 can cover large acreage efficiently at moderate rates, but high-volume orchard or vegetable work may force it to slow down.
T100S was specifically designed to address that bottleneck. Its high-flow system can keep the aircraft moving even when application volume rises, provided the pesticide label and drift conditions allow.
Spreading: 90 kg vs 50 kg
T40’s 70 L spreading tank carries up to 50 kg of compatible dry granules between 0.5 and 5 mm. T100S increases this to 126 L, up to 90 kg and an expanded ~0.5–10 mm supported particle range with the appropriate feed system.
For high-rate fertilizer, the difference can reduce refill frequency substantially. For light seed or small fields, T40’s capacity may already be enough to finish the job efficiently.
Lifting: A New Revenue Category
T40 was fundamentally designed around spraying and spreading. T100S adds a 95 kg lifting system with automatic route planning, trajectory recording, weighing, obstacle awareness and anti-sway control.
This creates possible agricultural logistics work that did not exist as a native T40 role: mountain supply transport, orchard input delivery, tool movement and other heavy cargo missions.
Obstacle Avoidance: T40 Was Advanced for Its Time
T40 uses active phased-array omnidirectional radar, backward/downward radar and a binocular vision system. DJI’s official T40 specification lists horizontal radar sensing out to 50 m under relevant conditions and a vision effective sensing speed up to 7 m/s.
T100S moves to a 256-line LiDAR plus next-generation radar and upgraded camera system. The improvement is not simply “more range”; it is a denser 3D model of the environment, persistent obstacle storage and smarter mapping.
Power Lines and Orchard Complexity
For a flat open field with no wires, the sensing difference may not determine daily productivity. For orchard rows, poles, guy wires or fields crossed by electrical infrastructure, the T100S’s finer obstacle-detection focus can significantly reduce mission-planning burden.

Battery Ecosystem: T40’s Installed Base Is Valuable
T40 uses the 30,000 mAh BAX601/DB1560-class battery ecosystem and D12000iE charging/generator architecture. Many fleets already own multiple batteries, chargers, generator parts and repair inventory.
T100S adds a newer heat-management concept with onboard battery cooling and ground air cooling. That is an operational improvement, but switching platforms can require replacing a large amount of battery and charging capital.
Parts Availability
T40 has years of accumulated parts demand and service knowledge. Ares Acres stocks and sources parts through the DJI T40 Parts collection. T100S will require its own exact component ecosystem as regional adoption grows.
This matters during peak application windows: a slightly less capable aircraft that can be repaired today can be more valuable than a flagship waiting a week for an imported sensor.
Transport and Field Setup
T40 is physically smaller and shorter. T100S uses larger 62-inch propellers and a wider deployed envelope. Operators moving to T100S should re-evaluate:
- trailer dimensions,
- battery racks,
- mixing/refill pump capacity,
- dry-material loading equipment,
- crew separation and launch-zone size,
- generator/charger electrical output.
Upgrade ROI: When T100S Makes Financial Sense
A T40 owner should not compare only purchase price. The correct question is how many productive hours the T100S can save.
The upgrade case is stronger when:
- T40 refills are consuming a large share of the day,
- high-volume applications force slow flight,
- fertilizer programs require frequent 50 kg refills,
- cargo lifting can generate separate revenue,
- obstacle-heavy terrain adds mapping labor,
- the operation has enough acreage to keep T100S utilized.
The case is weaker when:
- fields are small and scattered,
- application rates are low,
- existing T40 fleet and spares are paid off,
- crew/water logistics already limit output,
- T100S lacks official regional support.
Which Is Better by Use Case?
| Use case | Better fit |
|---|---|
| Large high-volume row-crop applications | T100S |
| Dense orchards | T100S |
| Large fertilizer spreading | T100S |
| Agricultural cargo transport | T100S |
| Mature fleet with existing batteries/spares | T40 can remain economically strong |
| Smaller transport footprint | T40 |
| Immediate mature parts support | T40 |

Final Takeaway
T100S demonstrates how far DJI’s agricultural platform has progressed since T40: more than double the liquid capacity, several times the pump flow, almost double the spread payload, a 95 kg lift system and much denser sensing. But an upgrade only creates value when the operator has enough acreage, material logistics and support infrastructure to use that capacity. A mature T40 fleet can remain profitable long after a newer flagship appears.
