DJI Agras T100 150L spreading system preflight checklist

DJI Agras T100 150L Preflight Guide: Blockage Prevention, Payload & IP67 Safety

September 17, 2026

The 150L Spreading System has a short list of pre-use checks that matter directly to spreading quality and system protection. DJI's source emphasizes material cleanliness, normal screw-feeder and spinner-disc operation, secure cable connections, app-recommended payload limits and the conditional nature of IP67 protection.

Quick Answer: Before each use, verify that the screw feeder rotates normally and the spinner disc operates normally. Use only dry material in the stated diameter range, remove caked fertilizer and foreign objects, confirm cables are secure, and never exceed the payload weight recommended by DJI Agras. Keep personnel away from the spreading system while it is operating.

Check screw-feeder movement before every use

DJI explicitly says to make sure the screw feeder functions normally before each use. If movement is abnormal, stop and inspect the feed path before loading or operating the system.

Relevant service parts include the T100 Auger Motor and Auger Motor Service Kit, but the source does not tell users to replace these parts solely because a preflight check fails. Diagnose the feed path first.

Check spinner-disc operation

DJI gives the same before-each-use requirement for the spinner disc. Confirm it operates normally and that the disc has clearance from cables or surrounding structure.

The active catalog includes the T100 Spinner Disk, Spinner Disk Motor, Spinner Disk Cable, and Spinner Disk Repair Kit.

Prevent blockage before material enters the feeder

Remove large clumps of caked fertilizer, woven-bag fragments, straw, gravel and other foreign objects from the material. The source says unsmooth discharge can affect spreading performance or cause blockage.

Respect the DJI Agras payload recommendation

The maximum loaded weight is not a single universal number in this product-information sheet. DJI says the Agras app will recommend payload weight according to the current aircraft status and surroundings. Do not exceed that recommended value.

Maintain safe distance from moving parts

Sharp and moving mechanical parts can cause injury. While spreading, maintain a safe distance from the spreading system. Do not attempt to disassemble factory-mounted components unless the source specifically permits that component to be detached.

Understand the IP67 limitation

T100 150L IP67 protection conditions collision cracked shell and loose covers — IP67 protection can decrease after collision, seal damage, loose covers, aging or wear.

Under stable laboratory conditions, DJI rates the spreading system IP67 according to IEC 60529. The source also states that this protection is not permanent, may decline with aging and wear, and does not make water damage a warranty-covered event. Protection can decrease if the seal structure is deformed in a collision, the shell seal is cracked or damaged, or waterproof covers are not properly secured.
