Warning
- The T30/T10 Spreading System 3.0 is only compatible with the DJI AGRASTM T30/T10 aircraft and the firmware of the aircraft must support the spreading system. Refer to the Specifications section for more information about compatibility. DO NOT use it with other products or for non-agricultural purposes.
- The spreading system is compatible with dry materials that have a diameter between 0.5-5 mm. DO NOT use with other materials. If used with other materials, the operating performance will be negatively affected and the spreading system may be damaged. All materials must be used in strict accordance with the instructions for those materials.
- The max load of the spread tank depends on the takeoff weight of the aircraft. DO NOT overload. Refer to the Specifications section for more information.
- When connecting the cables, make sure the connection is correct and secure. Operate with caution to avoid damaging the cables.
- Make sure that the hopper gate and spinner disk function normally before each use.
- Operate with caution to avoid injury caused by sharp or moving mechanical parts.
- While spreading, maintain a safe distance from the spreading system to avoid injury.
- While spreading, the detection distance range of the omnidirectional digital radar will be 5-30 m instead of 1.5-30 m due to obstruction from the materials being spread. Note that the aircraft cannot sense obstacles that are not within the detection range. The detection performance of the radar module will also decrease. Fly with caution. Refer to the disclaimer and safety guidelines of the aircraft being operated for more information on the radar module.
- Make sure to attach the corresponding waterproof cover if the liquid level gauge port or spreading system cable port are not in use. Otherwise, water may enter the port causing it to short circuit.
- DO NOT attempt to disassemble any part of the spreading system that has already been mounted prior to shipping. Unless this user guide states that part may be detached. Otherwise, the ingress protection performance will be affected.
- Under stable laboratory conditions, the spreading system has a protection rating of IP67 (IEC standard 60529) and can be cleaned using a small amount of water. This protection rating is not permanent, however, and may reduce over an extended period due to aging and wear. The product warranty does not cover water damage. The protection ratings of the aircraft mentioned above may decrease in the following scenarios:
- If there is a collision and the seal structure is deformed.
- If the seal structure of the shell is cracked or damaged.
- If the waterproof covers are not properly secured.
Introduction
The T30/T10 Spreading System 3.0 is compatible with the Agras T30/T10 aircraft
respectively and offers efficient and reliable spreading operations. The
spreading system comes up with a built-in stirring device and hopper gate
control structure to prevent material blockages and improve operating accuracy
and reliability. The weight sensors monitor the weight of the remaining
material in the spread tank in real time while the control module improves the
accuracy of the spread rate control and
empty tank warning. Fenders are included in the packaging and can block
spreading material that flies upward from damaging the propellers. Users can
configure spreading settings in the DJI Agras app and create specific
templates for different materials in order to meet different requirements. The
app also provides warning prompts for an empty tank as well as for
abnormalities in rotational speed, temperature, and hopper outlet size.

It is recommended to adjust the settings so that they are suitable for the materials you are using and perform a test to make sure the performance is as expected. It is recommended to do the following when spreading 45 kg/ha of materials in Manual operation mode.
- Adjust the hopper outlet size so that the material delivery rate is 8 kg/min.
- Adjust the spinner disk rotational speed so that the spreading range is 5 to 7 meters.
- Maintain a flight speed of approximately 5 m/s.
- Start the operation. The operations of the spreading system vary depending on the operation mode
Route Operation Mode
After starting an operation, the aircraft ascends to a preset takeoff altitude
and the spinner disk spins. When the aircraft reaches the starting point of
the route, the hopper gate opens and the aircraft flies along the route and
spreads material automatically. Spreading cannot be started or stopped
manually. The operation resumption function can be used during operation. Once
the operation is paused, the hopper gate closes automatically to stop
spreading while the spinner disk is still spinning. After the operation is
resumed, the aircraft returns to the breakpoint or projection point and
continues spreading.
A-B Route Operation Mode
Switch to A-B operation mode after the aircraft takes off and the spinner disk
begins to spin. When the aircraft reaches the first turning point, the hopper
gate opens and the aircraft flies along the route and spreads material
automatically.
Spreading cannot be started or stopped manually. The operation resumption
function can be used during operation. Once the operation is paused, the
hopper gate closes automatically to stop spreading while the spinner disk
continues to spin. After operation is resumed, the aircraft returns to the
breakpoint or projection point and continues spreading.
Manual Plus Operation Mode
Switch to M+ mode after the aircraft takes off and the spinner disk begins to
spin. The hopper gate opens and the aircraft spreads material automatically
once it has begun flying.
Manual Operation Mode
Switch to M mode after the aircraft takes off. Use the Spray button on the
remote controller to start or stop spreading manually.
In all operation modes except Manual operation mode:
- When the aircraft flies along spreading flight routes, the hopper gate opens automatically to start spreading.
