dji Agras T50 Agriculture Drones User Guide
Aircraft
The Agras T50 aircraft has an anti-torsion structure, offering reliable
operations. The integrated spraying system can quickly transform into the
spreading configuration with a spreading payload of up to 50 kg.
The aircraft is equipped with the phased array radar system and binocular
vision system, including downward and forward binocular vision, forward and
rear phased array radar. The systems provide 360-degree omnidirectional
obstacle sensing to ensure operational safety. The ultra HD FPV camera with a
tiltable gimbal can automatically collect HD field images for local offline
reconstruction to assist precise field planning.
The Coaxial Dual Propeller structure brings a strong wind field. Pesticides
can penetrate thick canopies to allow thorough spraying. The spraying system
is equipped with the Magnetic Drive Impeller Pump, Dual Atomized Sprinkler,
Anti-Drip Centrifugal Valve and solenoid valve, to ensure more efficient and
precise pesticide spraying, as well as save liquid pesticide. The spraying
system can be upgraded with two more sprinklers to meet different operation
scenarios.

Using the T50
Preparing the Intelligent Flight Battery
Only use official DJI flight batteries. Check the battery level before flying
and charge according to the corresponding manual document.
Preparing the Aircraft
Unfold the M3 and M4 arms, and fasten the two arm locks. Avoid pinching
fingers.
Unfold the M1 and M2 arms, and fasten the two arm locks. Avoid pinching
fingers.
Unfold the propeller blades.
Insert the Intelligent Flight Battery into the aircraft until you hear a
click.
- Make sure that the battery is firmly inserted into the aircraft. Only insert or remove the battery when the aircraft is powered off.
- To remove the battery, press and hold the clamp and lift the battery up.
- Fold the M1 and M2 arms followed by the M3 and M4 arms. Otherwise, the arms may be damaged.Getting Ready for Takeoff
Getting Ready for Takeoff
A. Place the aircraft on open, flat ground with the rear of the aircraft
facing toward you.
B. Make sure that the propellers are securely mounted, there are no
foreign objects in or on the motors and propellers, the propeller blades and
arms are unfolded, and the arm locks are firmly fastened.
C. Make sure that the spray tank and flight battery are firmly in place.
E. Power on the remote controller, make sure that the DJI Agras app is
open, and power on the aircraft. Tap Start in the home screen of the app to
enter Operation View. Make sure that the GNSS signals are strong and the
screen shows Ready to GO (GNSS) or Ready to GO (RTK). Otherwise, the aircraft
cannot take off.
RTK positioning is recommended. In the app, go to Operation View, tap RTK, and select a method for receiving RTK signals.
Calibrating the Flow Meter
Make sure to calibrate the flow meter in the following situations:
Change liquid payload with different viscosity.
The difference between the actual area and planned area is more than 15% after
the first operation.
Calibrating procedure
A. Get Ready to Calibrate
- Fill the spray tank with approximately 2 L of water.
- Press the Spray button to start or stop spraying manually in order to exhaust air
B. Calibrating the flow meter.
- In the app, go to Operation View, tap
then tap Calibration on the right of the flow meter calibration section. - Tap Start Calibration and calibration will start automatically. The result of the calibration will be displayed in the app when completed.
- After calibrating successfully, users can proceed with the operation.
- If calibration fails, tap the reminder to view and resolve the problem. Afterwards, re calibrate and wait for successful calibration.
Flight
In order for the aircraft to automatically take off and perform an operation, it is recommended to creat a plan for a field and select an operation before takeoff. Refer to the Starting Operations section for more information. For other scenarios, take off and land manually as follows.
Takeoff
Perform a Combination Stick Command (CSC) and push the throttle stick up to
take off.
Throttle Stick (left stick in Mode 2)
Landing
Push the throttle stick down until the aircraft lands. There are two methods
to stop the motors after landing.
Method 1: When the aircraft has landed, push and hold the throttle stick
down. The motors will stop after three seconds.
Method 2: When the aircraft has landed, push the throttle stick down, and
perform the same CSC that was used to start the motors. Release both sticks
once the motors have stopped.
- Spinning propellers can be dangerous. Stay away from spinning propellers and motors. DO NOT start the motors in confined spaced or where there are people nearby.
- Maintain control of the remote controller as long as the motors are running.
- DO NOT stop the motors mid-flight. Otherwise, the aircraft will be crashed. Stop the motors only in an emergency situation to reduce the risk of damage or injury.
- It is recommended to use Method 1 to stop the motors. When using the Method 2 to stop the motors, the aircraft may roll over if it is not completely grounded. Use Method 2 with caution.
- After landing, power off the aircraft before turning off the remote controller.
Starting Operations
Users can perform aerial surveying for the operation area in the DJI Agras app, receive an HD map via offline reconstruction in the remote controller. Field planning and identifying can be performed on the HD map before route operation. The following descriptions use Cross hair and Route Mapping and Route Mode as an example
- Power on the remote controller and then the aircraft. Enter Operation View in the DJI Agras app.
- Tap Mode button on the upper left corner and select Route Mapping in the Mapping panel.
- Tap on the bottom right of the sreen and select Area Route or Boundary Route.Then tap in middle of the right screen to select Crosshair in the Add Point list.
- Drag the map and tap Add to add a point at the cross hairs. Tap to save.
- Tap and move the slider to launch the aircraft. The aircraft will perform the mapping operation along the route and land automatically.
- Wait for the app to complete reconstruction. The reconstruction result will be displayed on the original map.
- Tap Identify Field, then tap an identified field to select it and adjust the boundary.
- Tap Mode button on the upper left and select Route in the Agriculture panel.
- Tap on the left and select a field in the field list.
- Tap Edit to edit field and set route parameters. Drag to adjust the flight direction of the route. Then save.
- Tap to use the field. Set task parameters and tap to save.
- Tap , check the aircraft status and task settings, and move the slider to take off. The aircraft will perform the operation automatically.
-
Only take off in open areas and set an appropriate Connection Routing and RTH Altitude according to the operating environment.
-
An operation can be paused by moving the control stick slightly. The aircraft will hover and record the breakpoints. After that, the aircraft can be controlled manually. Select the operation again to continue.
The aircraft will return to the breakpoint automatically and resume the operation. Pay attention to aircraft safety when returning to a breakpoint. -
In Route and Fruit Tree Operation modes, the aircraft is able to circumvent obstacles, which is disabled by default and can be enabled in the app. If the function is enabled and the aircraft detects obstacles, the aircraft will slow down and circumvent the obstacles and return to the original flight path.
-
Users can set the action the aircraft will perform after the operation is completed in the app.
More Operation Modes and Functions
Refer to the user manual for more information about the A-B Route Operation, Manual Operation, and Fruit Tree modes, and on how to use functions such as Connection Routing, Operation Resumption, System Data Protection, and Empty Tank.
