The DJI Agras T50 OEM Spreading System Reduction Gearbox, DJI material number BC.AG.SS000716, is the geared drive that converts the spreader motor’s high-speed output into the higher-torque, lower-speed rotation the spreading disc and metering auger actually need to move granular product. When the T50 is set up to spread rather than spray, this gearbox is the mechanical heart of the system.
Granular spreading is a torque-hungry job — dry product loads the disc and auger far harder than liquid loads a pump — and the reduction gearbox is what lets a compact motor deliver that torque without stalling. It is also, being the highest-load moving assembly in the spreading kit, the part that wears.
The gearbox multiplies motor torque and reduces speed through its gear train so the spreading disc turns product out in an even, controlled pattern and the auger meters reliably under load. When the gearset wears, the symptom is rarely a clean stop — it is noise, play, inconsistent disc speed under load, and a spread pattern that loses its evenness.
Confirm before you order: this gearbox is DJI part BC.AG.SS000716, listed for the DJI Agras T50 spreading system. Match the material number to your parts diagram before ordering, and inspect the spreader motor and disc coupling at the same time — a gearbox that has been run with play often takes its neighbors with it.
Why it fails: granular spreading combines high torque, abrasive dust, and duty cycling. Over time gear teeth and bearings wear, lubrication degrades, and abrasive intrusion accelerates both. Spreading duty is simply harder on a drivetrain than spraying duty.
Post-install checklist: mount the gearbox squarely, couple it to the motor and disc without preload or misalignment, confirm free rotation by hand, then spin it up unloaded to check for noise and runout before loading the hopper and verifying the spread pattern on a test pass.

Spreading is billed by the acre and judged by the evenness of what lands on the field, and both come off a disc that has to turn true and hold speed under load. A worn reduction gearbox quietly robs the spreader of the torque that makes the pattern even. Replace it and the spreading system gets its muscle back.
Gear it down. Hold the torque. Spread it even. Fly the field.

What is the DJI material number (part number) for the T50 Spreading System Reduction Gearbox? BC.AG.SS000716, per the official DJI Agras T50 parts list. A .01 or .F suffix on a physical label is the same part — the base number is BC.AG.SS000716.
What is the DJI Agras T50 Spreading System Reduction Gearbox? It is the geared reduction drive that steps the spreader motor down to the torque and speed the spreading disc and metering auger need to move granular product on the T50 spreading system.
Which DJI Agras model does it fit? The supplier lists this gearbox for the DJI Agras T50 spreading system. Confirm material number BC.AG.SS000716 against your parts diagram before ordering.
What are the signs it needs replacing? Grinding or whining from the drive, play or backlash at the disc, disc speed that sags under load, an uneven spread pattern with no metering fault, or lost grease and metal debris.
Why do spreading gearboxes wear out? Granular spreading combines high torque, abrasive dust, and constant duty cycling. Gear teeth and bearings wear and lubrication degrades faster than in lighter-duty drives.
Where can I buy a DJI Agras T50 spreading gearbox in the USA? Ares Acres, a U.S.-based authorized DJI Agras retailer, carries Reduction Gearbox BC.AG.SS000716 with free and fast U.S. shipping.
