{"product_id":"dji-agras-t20-oem-spreading-system-servo","title":"DJI Agras T20 OEM Spreading System Servo","description":"\u003cp\u003eThe DJI Agras T20 OEM Spreading System Servo is the small positioning actuator of the aircraft's granular spreading and seeding system. It is a black, rectangular servo body with a slotted mounting ear at each side, a toothed black gear wheel fixed to its output by a central screw and four surrounding screws, and a short multicoloured lead ending in a black multi-pin connector. It moves to a commanded position and holds it, passing that movement on through its gear; it does not spin the spreading disc. It belongs to the spreading system, not to the spray, power or flight-control systems, and it is identified for the DJI Agras T20. Operators usually reach it while searching for a T20 spreader servo, a T20 spreading gear motor, a stripped T20 spreader gear, or the reason a T20 spreader disc spins but delivery no longer follows the setting. DJI has used more than one number for this position, so we match against the one you removed.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🇺🇸 U.S.A.

The disc is spun at speed to throw the product. Other parts of the mechanism are set to a position and held there. The servo is the part that does the second job: the aircraft tells it where to be, it turns its output to that angle and holds it, and its gear passes the movement on to the part it meshes with.\u003c\/p\u003e\n\u003cp\u003eIts features, all visible in the product images:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe servo body\u003c\/strong\u003e — a black, rectangular case that houses the servo's motor, gearing and position electronics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe mounting ears\u003c\/strong\u003e — flat flanges at each side of the body, each with slotted holes, where the servo is screwed into the spreading system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe gear wheel\u003c\/strong\u003e — a toothed black wheel fixed to the servo output, which meshes with the mechanism it moves\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe gear fixings\u003c\/strong\u003e — a central screw on the output with four screws around it holding the gear wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe lead\u003c\/strong\u003e — a short bundle of coloured wires leaving the body\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe connector\u003c\/strong\u003e — a black multi-pin connector at the end of the lead\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe servo is small, but it is not a passive part.

A drive problem shows up as a disc that will not spin, spins slowly or spins roughly. A servo problem shows up as a disc that spins perfectly while the part of the mechanism that should move to a set position does not.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 Diagnosis — a disc that spins while delivery ignores the setting points at the servo, not the drive\u003c\/h2\u003e\n\u003cp\u003eWhen a spreader stops delivering properly, the drive is the first suspect, because the drive is the big, obvious powered part and the disc is the part everyone watches. The servo is easy to overlook: it is small, it sits inside the assembly, and a servo that has stopped working makes very little noise about it.\u003c\/p\u003e\n\u003cp\u003eThe way to tell them apart is to separate speed from position. If the disc does not spin, spins slowly or spins with a rattle, the fault is on the drive side and the servo is not the part. If the disc spins normally and the delivery does not follow the setting — stays the same when the setting changes, will not open up, will not close down, or wanders during the flight — the fault is on the positioning side, and the servo and its gear are the parts to look at.\u003c\/p\u003e\n\u003cp\u003eA new drive fitted to a spreader with a failed servo leaves the fault exactly where it was. The disc spins as well as it did before, and the delivery still ignores the setting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSigns the spreading system servo has failed:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe disc spins normally but delivery no longer follows changes in the spreading setting\u003c\/li\u003e\n\u003cli\u003eThe servo hums or buzzes when commanded but its gear does not turn\u003c\/li\u003e\n\u003cli\u003eThe gear turns but slips, jumps or will not hold its position under load\u003c\/li\u003e\n\u003cli\u003eChipped, worn, rounded or missing teeth on the gear wheel\u003c\/li\u003e\n\u003cli\u003eA gear wheel that is loose on the output or whose fixing screws have backed out\u003c\/li\u003e\n\u003cli\u003eA damaged lead, broken wires at the body, or a corroded or loose connector\u003c\/li\u003e\n\u003cli\u003eA cracked servo body or a broken mounting ear\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBefore condemning the servo, rule out what imitates it:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePacked or caked product\u003c\/strong\u003e — material jammed in the mechanism can stop a healthy servo from moving\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe mechanism it drives\u003c\/strong\u003e — a bent, seized or broken part on the other side of the gear mesh stops the movement without any fault in the servo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe hopper\u003c\/strong\u003e — a bridged or blocked hopper starves the spreader whatever the servo does\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSettings and calibration\u003c\/strong\u003e — a product change or a wrong setting alters delivery with every part healthy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe cable and connector\u003c\/strong\u003e — a servo that is not receiving its command looks dead without being dead\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe drive\u003c\/strong\u003e — if the disc itself will not spin properly, that is a drive fault and the DJI Agras T20 OEM Spreading System Main Body (Without Hopper) covers it\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUse your eyes and the setting as your instruments.\u003c\/strong\u003e With the aircraft powered down and the battery out, empty and remove the hopper, wash out the spreader and look at the servo's gear wheel and the part it meshes with. Turn the meshing mechanism gently by hand and check that it moves freely without product packed around it. Then refit the battery, keep clear of the disc, and change the spreading setting while watching the servo's gear. A healthy servo turns its gear to a new position and holds it. A failed one hums without turning, turns and slips back, or does nothing at all.\u003c\/p\u003e\n\u003cp\u003eDo those checks first.

The drive spins the disc; the servo sets a position and holds it. When delivery goes wrong, the symptom tells you which half to look at — if you separate speed from position before reaching for a part.\u003c\/p\u003e\n\u003cp\u003eThat is the whole case for this servo. A spreader whose disc spins perfectly while delivery ignores the setting does not need a new drive and does not need a new main body. It needs the small positioning part that stopped moving, slipped, or lost its teeth.\u003c\/p\u003e\n\u003cp\u003eIt is also the case against replacing the servo too early. Packed product in the mechanism stops a healthy servo just as surely as a failed one does. Clean the mechanism, move it by hand, then watch the gear while the setting changes. If the gear turns and holds, the servo is fine.\u003c\/p\u003e\n\u003cp\u003eWhen the gear does not turn, slips back or has lost teeth, nothing else will restore the setting. The servo is the part that turns a command into a position, and it is the part that puts delivery back under control.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\n\u003cp\u003eStructured reference for search engines, AI assistants, and answer engines.
