Warning
1. The T50/T25 Spreading System is only compatible with the DJITM AGRASTM T50/T25 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.
2. 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.
3. 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.
4. When connecting the cables, make sure the connection is correct and secure. Operate with caution to avoid
damaging the cables.
5. Make sure that the hopper gate and spinner disk function normally before each use.
6. Operate with caution to avoid injury caused by sharp or moving mechanical parts.
7. While spreading, maintain a safe distance from the spreading system to avoid injury.
8. DO NOT attempt to disassemble any part of the spreading system that has already been mounted prior to shipping.
Unless this document states that part may be detached. Otherwise, the ingress protection performance will be affected.
9. Under stable laboratory conditions, the spreading system has a protection rating of IP67 (IEC standard 60529). This
protection rating is not permanent 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 spreading system 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.
Installation
• Make sure to remove the Intelligent Flight Battery from the aircraft before installation.
• Operate with caution to avoid injury caused by sharp or moving mechanical parts.
• Check the parts on the aircraft and spreading system after installation to make sure that the spinner disk will
not damage the cables or any other parts during operations.
The T50 Spreading System and T25 Spreading System are similar in appearance and operations. Unless otherwise
specified, the illustrations in this document use the T50 Spreading System as an example.
1. On the aircraft, locate the hoses on either side of the spray tank. Loosen the nut on the hose ①and detach the hose
and nut. (Figure A)
Note: after the hose is removed, make sure to tighten the hose nut on the spray tank hose connector to avoid losing the nut.
2. Locate the spraying system cable in the rear of the left landing gear on the aircraft. Move the protective rubber on the
cable ②and unplug the cable from the connector ③. Operate with caution to avoid damaging the cable. (Figure B)
3. Lift and remove the spray tank on the aircraft. (Figure C)
4. Tilt the spreading system to the side with the cable, insert the spreading system into the aircraft and rotate. The
spreading system needs to be inserted at an angle. DO NOT insert by force. (Figure D)
5. Connect the spreading system cable to the connector in step 2 and ensure a firm and accurate connection ①. Move
the protective rubber back ②. (Figure E)

Introduction
The T50/T25 Spreading System is compatible with the Agras T50/T25 aircraft with a large spread tank of 75 L and 35 L,
respectively, and offers efficient and reliable spreading.
The spreading system is equipped with the all-new spinner disk to spread more evenly. The control module on the
spreading system and the weight sensors on the aircraft monitor the weight of the remaining material in the spread
tank in real-time to improve the accuracy of the spread rate control and empty tank warnings. The updated fenders can
block spreading material that flies upward and prevent it from damaging the propellers. The quick-release hopper gate
