It is not part of the aircraft's flight electronics and it is not part of the hopper. It sits between the two, taking direction from the aircraft and the spreading system and turning it into commands the material-delivery mechanism can act on. Supplied brand new, never installed and never flown.\u003c\/p\u003e\n\u003cp\u003ePhysically it is an electronic module in a protective housing with a connector interface into the spreader harness and defined mounting points on the spreading assembly. Housing shape, connector layout, and mounting pattern are what separate one generation of module from the next, which is why the module you remove should be compared directly against the replacement rather than matched from a photograph.\u003c\/p\u003e\n\u003cp\u003eThis module is supplied for DJI Agras T40, T20P, T30, and T10 aircraft running the corresponding spreader control architecture. Those airframes share a spreading-system family, but they do not share every revision of every component within it, so the spreader generation actually installed on your aircraft matters as much as the model number on the airframe. Confirm both before ordering.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eIn normal operation the module forms part of the electronic control path between the aircraft, the spreading system, and the mechanisms that move material out of the hopper. It participates in controlling and coordinating spreading-system operation, so granular product is delivered when the aircraft calls for it and held back when it does not. Spread rate, timing, and coverage all depend on that control path staying intact.\u003c\/p\u003e\n\u003cp\u003eWhen the module fails, the failure does not look mechanical. The hopper is full, the dispensing hardware turns freely, nothing is visibly broken, and the spreader still will not respond correctly. That is the signature of a control-path fault rather than a material-handling fault, and it is the reason operators lose an afternoon inspecting the hopper when the problem sits upstream of it in the electronics.\u003c\/p\u003e\n\u003cp\u003eA partial failure costs more than a clean one. An intermittent module can spread normally through part of a pass and drop out for the rest, which shows up afterward as striping, skipped ground, or an application rate that does not match the plan. By the time the pattern is visible in the field the product is already down, so intermittent spreading behavior deserves the same attention as a spreader that will not start at all.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\n\u003cp\u003eSpreading system fails to initialize when the aircraft is powered up.\u003c\/p\u003e\n\u003cp\u003eSpreader does not respond to commands even though the hopper is loaded and the dispensing hardware turns freely.\u003c\/p\u003e\n\u003cp\u003eIntermittent spreading during a pass that inspection traces to the control electronics rather than to a jam.\u003c\/p\u003e\n\u003cp\u003eSpreading stops partway through a job and then resumes on its own.\u003c\/p\u003e\n\u003cp\u003eVisible connector or housing damage on the installed module.\u003c\/p\u003e\n\u003cp\u003eMoisture, corrosion, or electrical damage found on the module or inside its connector.\u003c\/p\u003e\n\u003cp\u003eBent, pushed-back, or contaminated pins where the spreader harness meets the module.\u003c\/p\u003e\n\u003cp\u003eDiagnostic substitution or service testing isolates the controller as the faulty component.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e📐 Specifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePart:\u003c\/strong\u003e Spreader Control Module\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComponent type:\u003c\/strong\u003e Electronic control module for the DJI Agras spreading system\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct category:\u003c\/strong\u003e DJI Parts\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible aircraft:\u003c\/strong\u003e DJI Agras T40 \/ T20P \/ T30 \/ T10\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunction:\u003c\/strong\u003e Electronic control path between the aircraft, the spreading system, and the material-delivery mechanism\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAssembly scope:\u003c\/strong\u003e Control module only — hopper and dispensing assembly are not included\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQuantity supplied:\u003c\/strong\u003e 1 × Spreader Control Module\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Brand new — never installed, never flown\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShips from:\u003c\/strong\u003e United States\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🧰 Fitment Verification Before You Order\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eConfirm fitment by part number before ordering.\u003c\/strong\u003e Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRevision suffixes are still the same part.\u003c\/strong\u003e DJI labels sometimes carry a trailing revision such as \u003cem\u003e.01\u003c\/em\u003e, \u003cem\u003e.02\u003c\/em\u003e, or \u003cem\u003e.F\u003c\/em\u003e.

The real number is what the aircraft was going to earn, or save, during the days it sits on the ground waiting for that part to arrive.\u003c\/p\u003e\n\u003cp\u003eA commercial Agras airframe covers a meaningful block of acreage in a working day. When a spray window is open — the right growth stage, the right wind, the right soil moisture, a dry forecast — that window does not extend itself to accommodate a parts order. It closes. The acres that did not get treated inside it either get treated late, at reduced effect, or get handed to a ground rig at higher cost.\u003c\/p\u003e\n\u003cp\u003eAgainst that, the cost of a single OEM component is small, and the cost of holding one on the shelf before it fails is smaller still. Operators who run on schedule tend to be the ones who stock the parts they already know will wear out, rather than the ones who order fastest after a failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor the Spreader Control Module, that logic is straightforward:\u003c\/strong\u003e it is an inexpensive component relative to the DJI Agras T40 \/ DJI Agras T20P \/ DJI Agras T30 \/ DJI Agras T10 it serves, it is a known service item rather than a surprise, and having one in the truck or the shop converts a multi-day grounding into an afternoon of work.\u003c\/p\u003e\n\u003cp\u003eThis is also why we ship from U.S. stock rather than drop-shipping from overseas. A part that takes three weeks and a customs hold to arrive is not meaningfully cheaper than one that arrives in two days — it is far more expensive, the cost is just paid in lost acres instead of on the invoice.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e💡 Why This Part Matters\u003c\/h2\u003e\n\u003cp\u003eA spreading aircraft with a dead control module is a fully airworthy machine that cannot earn. The rotors turn, the batteries are charged, the hopper is loaded, and none of it matters, because the component that tells the material-delivery mechanism what to do is not answering. That is the most expensive kind of failure to own: everything else on the aircraft is ready and the job still does not happen.\u003c\/p\u003e\n\u003cp\u003eSpreading work runs on windows that do not wait. Fertilizer timing, seeding dates, and granular applications are set by the crop and the weather, not by a parts order. Acres that miss their window get treated late at reduced effect, get handed to a ground rig at higher cost, or do not get treated at all. Against those numbers the price of the module is a rounding error, and the price of having one already on the shelf is smaller still.\u003c\/p\u003e\n\u003cp\u003eGetting the diagnosis right matters as much as getting the part quickly. A control module is not a blind fix for every spreading error. Loose connectors, damaged wiring, a jammed dispensing mechanism, a failed sensor, or a spreader configuration that does not match the aircraft all produce overlapping symptoms.

The hopper, the dispensing hardware, and the rest of the spreading assembly are separate components and are not included. If you need any of those as well, send us your aircraft model and the spreader generation you are running and we will quote them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan a wiring or connector fault look exactly like a failed control module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, and it often does. Loose connectors, chafed or broken wiring, and interrupted power delivery all produce the same no-response behavior as a dead controller. Harness and connector inspection should be part of the diagnosis before the module is replaced, not after.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe spreader will not start at all. Is the module always the cause?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. A spreader that will not initialize can also come from a jammed dispensing mechanism, a sensor fault, a power-supply problem, or a spreading-system configuration that does not match the aircraft. The module is a strong candidate once those have been ruled out, not before.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes one module cover the T40, T20P, T30, and T10?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis module is supplied for those aircraft where they use the corresponding spreader control architecture. Spreading systems were revised across that range, so confirm the spreader generation installed on your aircraft and compare the housing, mounting points, and connector layout against the module you are removing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat should I check before I order a replacement module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFour things. Confirm the aircraft model. Confirm which spreader generation is installed. Compare the housing and connector layout to the part you are removing. And confirm that your diagnosis actually points at the controller rather than at the harness or the mechanical path.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan moisture or fertilizer dust kill the module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMoisture, corrosion, and electrical damage are among the normal reasons these modules are replaced. Granular product and washdown water both find their way into connectors. When you have the assembly open, inspect the connector for contamination and moisture and make sure seals go back correctly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat test should I run after installing the module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePower the aircraft up and run a controlled functional test of the spreading system before you load material. Confirm the spreader initializes, responds to commands, and reports no new errors. Only then load product and fly a check pass. Finding a problem with an empty hopper is far cheaper than finding it over a field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs intermittent spreading an electronics problem or a mechanical problem?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt can be either, which is why it needs to be traced rather than guessed. Partial jams, worn dispensing hardware, and sensor faults produce intermittent delivery just as a failing controller does. Inspect the mechanical path and the harness first, and treat the module as the answer only when the fault follows the electronics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this fit my aircraft?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis part is supplied for the DJI Agras T40 \/ DJI Agras T20P \/ DJI Agras T30 \/ DJI Agras T10.

Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work.
