Aircraft
Maximum flight altitude: 30 m Maximum transmission distance: 3 km (measured at a flight altitude of 2.5 m) Maximum flight speed: 10 m/s, Maximum operational flight speed: 7 m/s Takeoff time: 15 minutes (when weighing 27.5 kg), 10 minutes (when weighing 42.6 kg)
The T20 can spray up to 12 hectares per hour (29.65 acres) with a spray width of 6.5 m, a speed of 6.5 m/s, and an altitude of 2 m.
As displayed in the graphic below, the M2, M4, and M5 propellers rotate clockwise. The M1, M3, and M6 propellers rotate counterclockwise.
The layout and rotational direction of the propellers on the T20 create a steadier downward air-flow, which reduces the effect of upward mist, increases the spray width, and generates better sedimentation.
Yes
After powering on the aircraft and allowing it to perform a self-check, press and hold the power button for five seconds to begin linking the two devices.
The T20 is equipped with the RTK+GNSS Dual Redundancy System. There is not a separate version.

Yes. The T20 can be quickly folded to 25% of its original size.
No. You must press and hold the power button on the battery to start the T20.
They can be compatible via a software upgrade.
It is recommended that you keep a distance of at least 10 m.
Spraying System
The standard spray tank can hold 15.1 L of liquid, and the maximum volume is 20 L. Operators can replace the spray tank quickly.
Yes, but you need to replace the lotus base, check valve and other accessories. For details, please call the aftersales staff at 4007000303.
Note: If T16 is attached with a T20 tank, its load cannot exceed 15kg due to the battery power.
2-4kg/cm²
When equipped with the SX11001VS nozzle, the T20 can spray at a rate of 3.6 L/min. When equipped with the SX110015VS nozzle, it sprays at a rate of 4.8 L/min.When equipped with the XR11002VS nozzle, it sprays at a rate of 6.0 L/min.
Yes.
The T20 is equipped with a 4-channel electromagnetic flow meter, which has made calibration for the pumps and the discharging of air bubbles incredibly easy. With a closed-loop control technology, spraying precision and evenness of a single pipe has greatly improved.
Yes.
Radar
It supports horizontal obstacle avoidance in all directions, autonomous detour and terrain adaptation.
The horizontal obstacle avoidance function can detects obstacles in a 360º sweep of T20, slows the drone down as it approaches obstacles to avoid the obstacles with the drone hovering in place.
The autonomous detour function generates an optimal path to avoid unexpected obstacles.
The terrain adaptation function changes the altitude of the drone in response to changes in terrain height to ensure a constant relative height to the ground.
T20’s high-precision radar can be installed and used on T16.
Note: To do this, you must upgrade T16 to V02.03.0135 or higher version and replace its landing gear and radar bracket.
Find the radar settings in the operation interface and enable the edge sweeping radar function.
T20 will start to decelerate when its radar detects an obstacle with a diameter above 1 cm 15 meters away, and hover in place about 2.5 meters away from the obstacle.
Orchard Mode 3.0
Continuous spray - automatic isometric planning




Continuous spray - automatic tree center planning




Continuous spray - semi-automatic planning




Continuous spray - manual planning




Spot spray - automatic tree center planning




Spot spray - semi-automatic planning
In addition to normal operations on orchards on level terrain, the Fruit Tree Mode is better suited for crops on mountainous or uneven terrain with large altitude changes, such as tea crops, orange orchards, and peach orchards in mountainous regions.
DJI Terra requires Windows 7 or above (64-bit).
No. Ordinary aerial photography drones cannot guarantee the precision.
This is not supported currently.
Yes, RTK is required to ensure the precision of planning and operation.
Operation
On the startup interface of the remote control, tap , “Remote Control” and then “Pair” to trigger paring by the remote control. Turn on T20 and then press and hold the battery power button for 5s to trigger pairing of the drone. Wait a few seconds for the devices to pair.
On the operation interface, tap the spray button and hold it for 2s to remove the air in the pipeline; Alternatively, go to the Settings interface of the spray system and tap “Start Removing” to remove the air in the pipeline.
Remote Control 2.0, T20 Aerial Application Drone, network RTK, 2600W four-channel smart charger, and RTK high-precision positioning module need to be activated.
T20 can work:
(1) With the RTK signals provided by the D-RTK 2 mobile station;
(2) With the GNSS positioning by disabling the RTK positioning function.
Yes.
(1) Manual mode, which allows flexible operation and applies to small plots, edge sweep, and operations in mountainous terrain;
(2) Enhanced Manual mode, in which the course is locked to reduce missing spray in the manual operations. This mode applies to small plots and mountainous terrain;
(3) Points A-B mode, which allows to engage automatic flight quickly, and applies to plots in regular shapes such as rectangles, triangles and trapezoids;
(4) Flightpath Mode, which allows fully autonomous flight, and applies to plots in irregular shapes, large plots, and fruit trees on level ground;
(5) Fruit Tree mode, which supports fully autonomous flight along 3D flightpaths, and applies to tea plantations and fruit tree orchards on mountainous terrain or slopes and other plots on undulating terrain.
Follow “DJI Agriculture” on Facebook, Twitter, or YouTube to view video tutorials.
Log into https://www.dji.com/cn/flysafe/custom-unlock and follow the instructions to submit the necessary application materials.
On the main interface of the remote control app, find the Firmware Update interface in the bottom-left corner. Download the latest firmware to update the remote control and drone. For detailed instructions, follow the “DJI Agricultural Services” official account on WeChat and watch relevant videos.
Stay at least 5m away from the drone during operation.
Battery and Charger
Yes, but when you use the battery of T16 on T20, be sure that the load does not exceed 15kg.
For the smart battery of T20, 600 cycles is under warranty. Charging and discharging by at least 80% is counted as 1 cycle.
Yes. However, the T-series batteries cannot be charged simultaneously with the MG-series batteries.
Slow mode: The charger can charge four batteries simultaneously to full charge in about 80 minutes;
Fast mode: The charger can charge one battery at a time to full charge in 15-20 minutes.
The actual power of the generator must be 3000W at least. With factors such as generator aging considered, we recommended that the rated power of the generator shall be greater than 3500W.
Spreading System

T16 and T20.
For detailed instructions, follow the “DJI Agricultural Services” official account on WeChat and watch relevant tutorial videos.
The spreading system can spread granules with a diameter of 0.5-5mm.
Obstacle Avoidance
No. When using the active obstacle circumvention feature, the T20 can circumvent obstacles automatically without manual operation.
Obstacle point cloud imaging operates through digital beamforming technology. The obstacle’s width, directional angle, and location can be sensed in real time so that the T20 can bypass it.
The omnidirectional digital radar can sense obstacles horizontally and covers 360°.
T20’s high-precision radar can be installed and used on T16. Note: You must upgrade T16 to use this function.
Yes. However, it is less effective when flying up complex hilly terrains.
AI Operation Planning
After capturing orthographic images with the Phantom 4 RTK, use DJI Terra, which supports Orchard mode, to complete a 3D mapping of the field. Once the operation field is selected, the AI system will automatically identify various attributes, such as crops and obstacles, and automatically generate 3D operational routes. After these routes are downloaded, the T20 will then begin working automatically.
DJI Terra can identify orchards, buildings, water surfaces, and utility poles.
Yes. DJI Terra can recognize the location and height of fruit trees thanks to 3D mapping and AI recognition. The T20 only targets fruit trees and adjusts its flight altitude according to the height of the tree, ensuring a consistent distance while operating.
Remote Controller
The internal battery of the T20 can last for about 120 minutes, and the intelligent battery can last 120 minutes.
T20's remote control has a CPU with a 50% higher hashrate, so that the apps run more smoothly.
Yes. The external high-precision positioning module can obtain incredibly precise information, assist in flight planning, and improve operation efficiency and flight safety.
You can run firmware upgrades by using DJI Assistant 2 or by downloading the SD card firmware package from dji.com.
