DJI Agras T100 remote operations: staffing spray seasons, and what can and cannot be done from afar

The T100 is a 175 kg spray drone flown by a crew at the field edge. Remote work on it is planning, records and support, not flying. Here is how to staff a season honestly.

The DJI Agras T100 is a heavy agricultural drone that sprays from a 100 L tank, spreads from a 150 L hopper, and lifts up to 100 kg on a rope. It weighs 75 kg empty in its two-nozzle spraying configuration and up to 175 kg at takeoff. Unlike the docked aircraft elsewhere in this section, it is flown by a crew standing at the field edge with a controller, and it should be. Remote operations matter here for a different reason: spray work is seasonal and time-critical, and the work around each flight (field mapping, scheduling, records, weather calls) is where a lot of time and compliance risk sits.

What remote support can and cannot do on an Agras

Cannot: fly it from an operations center

DJI's T100 pages describe flight with the RC Plus 2 and the Agras Relay, with relay range of 8 km under FCC rules at 2.5 m height in clean conditions. They do not describe cloud-based live flight control, and nothing in this page's sources supports flying a T100 remotely. Plan for an on-site pilot for every flight.

Can: plan the work

Field boundaries, obstacles, application rates and route parameters prepared before the crew arrives, so a long day is spent spraying rather than mapping.

Can: run the season

Scheduling across fields and crews, weather go and no-go calls against the T100's limits (0 to 40 °C, wind under 6 m/s), battery and generator logistics, and job tracking.

Can: keep the records

Application records, flight logs and field outputs filed by farm, field and job, which is what auditors, customers and agronomists ask for afterwards.

We are explicit about this because the rest of our drone work is remote flying. On the T100, the pilot in command is at the field. A remote desk makes that pilot more productive; it does not replace them.

How the T100 works in the field

The crew flies with the DJI RC Plus 2, which the T100 FAQ says is also compatible with the T70P but not the T25P. DJI lists brighter screen, longer runtime with internal and external batteries, backlit buttons for night work and more customizable buttons as its upgrades over the T50's controller; the RTK module is not included as standard. The D-RTK 3 AG and the Agras Relay extend positioning and link range around the field.

Spraying

A 100 L tank and a pump rated at 30 L/min in the two-nozzle setup (40 L/min with four), which DJI says is an 87.5% increase over the T50. Single-side spraying switches on only the boundary-side nozzle when the aircraft turns at a field edge, or the obstacle-side nozzle when it bypasses an obstacle. The spraying system is not compatible with the T50's.

Spreading

A 150 L tank with a 3 to 10 m effective width.

Obstacle sensing

LiDAR to identify wires, poles, towers and trees, mmWave radar that works day or night and in fog, and Penta-Vision for takeoff and landing. When the aircraft meets an unmarked obstacle it recognizes and remembers its location, and one click on the controller saves it to the field so the route bypasses it next time. DJI rates effective avoidance at speeds up to 13.8 m/s and heights of 1.5 m or more, so very low passes lean on the saved obstacle map and the pilot's eyes.

Charging

The DB2160 battery charges from 30% to 95% in 8 to 9 minutes under DJI's test conditions. The D14000iE generator does not connect to grid power, and the C12000 charger needs a three-phase generator rated at 15,000 W or more, so power logistics are planned before the season, not on the morning.

Lifting: a second job with its own rules

With the lifting system fitted, the T100 carries up to 100 kg (80 kg with the dual-battery module, which adds endurance and a fuse for faster emergency release). DJI recommends a rope of 10 to 15 m: too short and the load can swing into the propellers, too long and it can hit the ground or snag on trees and wires. DJI does not recommend lifting in strong wind, since the load keeps swinging, especially with a large windward surface. Lifting is a different skill from spraying, and a crew trained for one is not automatically ready for the other, so it gets its own procedure, its own checklist and its own training flights.

Running an Agras season from a remote operations desk

One-to-many supervision

Here it means one desk supporting several crews, not one pilot flying several aircraft. The desk tracks where each crew is, what is left on the day's list, and which crew is waiting on batteries, product or a weather window.

Mission planning

Field boundaries, saved obstacles, buffer zones, rates and route settings prepared and checked per field, then handed to the crew. Fields flown last season start from last season's saved obstacles.

Takeover

On an Agras the desk does not take control. Its job is the stop call: wind rising past the limit, someone entering the area, a reported problem. Crews and desk agree in advance who makes that call and how it is acknowledged.

Airspace and visual observers

Fields near airports, heliports or other low-flying traffic are flagged during planning so the crew arrives knowing the airspace and any coordination the operation requires. Long fields with poor sight lines get an observer plan before the day starts.

Data delivery

Per-field records of what was applied, where and when, with flight logs and any imagery attached, tagged by farm, field and job and delivered to the grower, the agronomist or your own records system.

DJI lists the SmartFarm app and SmartFarm Web as its software around the Agras line. Whatever tools a program uses, the value of the desk is that the same people prepare and file every job, so the records look the same whichever crew flew it.

What a good T100 crew does differently

Walks or surveys the field edges for wires and poles before the first flight, and saves every obstacle the aircraft flags so later passes route around it.
Stops at the wind limit. Under 6 m/s is the aircraft's limit; drift and label restrictions on the product being applied may be tighter.
Keeps the generator, charger and battery rotation matched, so the aircraft is never waiting on power.
Logs every load: product, rate, field, time and conditions, so the record is complete without reconstruction later.
Keeps people out of the operating area and treats the aircraft as the heavy machine it is.

US regulatory notes, as of October 2026

Weight

Part 107 defines a small unmanned aircraft as one weighing less than 55 lb at takeoff, everything on board included (14 CFR §107.3). At up to 175 kg, the T100 is well outside that definition. Part 107 itself does not apply to operations an exemption holder conducts under an exemption issued under 49 U.S.C. §44807, the statute that lets the FAA use a risk-based approach to decide how such aircraft may operate.

Agricultural operations

Dispensing an economic poison (pesticides, herbicides and the like), or substances for plant nourishment or soil treatment, is an "agricultural aircraft operation" under 14 CFR §137.3, and Part 137 governs those operations and their certificates.

FCC and tariffs

The FCC Covered List action of 22 December 2025 blocks new authorizations for foreign drones but does not ground owned aircraft, and firmware updates for authorized DJI devices continue to at least 1 January 2029. DA 26-758 names aircraft of 55 lb or more and economic-poison spraying among its seven proposed categories, so the T100 falls under two. Since 3 September 2026, aircraft over 55 lb carry a 100% Section 232 tariff, per DroneXL.

This summarizes regulation text and public reporting, not legal advice. Confirm your own exemption and certificate requirements with the FAA and counsel.

If DJI Agras sales stop

The FCC proposal would not ground T100s already in service, and firmware support runs to at least 2029, so a fleet bought now keeps working. What it would change is fleet growth and replacement: new foreign spray aircraft in the 55 lb-plus and spraying categories would stop being imported after a wind-down if the proposal is adopted. Programs planning several seasons ahead should keep their crew procedures, records and field data platform-neutral, so that a change of aircraft is a retraining exercise rather than a restart. Our agriculture and infrastructure page covers the wider picture.

T100 vs T50

DJI's own comparisons are on the controller and the spray system: the T100's RC Plus 2 is brighter, longer-running and better for night work than the T50's controller, and the T100's pump flow is 87.5% higher, with a spraying system that does not interchange with the T50's. The T100 also adds the lifting role. For crews moving up from a T50, the main adjustments are a heavier aircraft, new power logistics and the lifting procedures if they use them.

How RoboPilots supports Agras programs

We train a dedicated group of operators on your aircraft, fields and record-keeping, and they work from a remote desk on planning, scheduling, weather calls and records, alongside the certified crews who fly on site and inside the exemptions and certificates your operation holds.

One-week trial

A short run during live work sets the flights-per-pilot-shift baseline for your crews and shows how much planning and record time the desk takes off them.

Coverage

Shifts across time zones, including US Pacific, to match early starts and long days in season.

Data

Application records, field outputs and flight logs tagged by site and mission (farm, field and job).

Availability: The Agras T100 shares FCC grant SS3-T100A2411 with the DJI FlyCart 100, according to DroneXL. US availability of new T100 units was not confirmed in the sources for this page; check with a DJI Agriculture dealer. The FCC's proposed DA 26-758, not final as of October 2026, names both aircraft of 55 lb or more and pesticide (economic-poison) spraying among the categories whose import and sale would end after a wind-down; aircraft already owned would not be grounded.

Frequently asked questions

Is the RC Plus 2 compatible with the Agras T70P and T25P?
DJI says the T100's RC Plus 2 is compatible with the T70P but not with other models, so the T25P is not supported.
What upgrades does the T100 controller have over the T50's?
DJI lists stronger performance, a brighter screen, longer runtime with internal and optional external batteries, backlit buttons for night use and more customizable buttons. The RTK module is not included as standard.
What rope length should be used for lifting with the T100?
DJI recommends 10 to 15 m. A shorter rope lets the load swing into the propellers; a longer one risks the load hitting the ground or snagging on trees or wires.
Can the T100 lift in strong wind?
DJI does not recommend it. Wind keeps the load swinging, which compromises flight safety, especially with cargo that has a large windward surface.
What is the difference between the standard and dual-battery lifting modules?
The standard module carries up to 100 kg. The dual-battery module carries 80 kg but holds two batteries for longer endurance and adds a fuse for a quicker, safer emergency release.
Can an Agras T100 be flown remotely from an operations center?
Not on the basis of DJI's published T100 material, which describes flight with the RC Plus 2 and a relay at the field. Remote teams can handle planning, scheduling and records, while a certified pilot flies on site.
