DJI Agras T40 OEM Complete Solid Dispenser / Spreading System Assembly

DJI Agras T40 OEM Complete Solid Dispenser / Spreading System Assembly — a complete dry-material application payload for the DJI Agras T40, designed to meter and distribute granular fertilizer, seed, feed, and other compatible solid materials. This assembly combines the hopper, metering hardware, spreading drive components, and discharge system required to convert or restore a T40 for dry-product application.

🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

Ares Acres LLC supports commercial DJI Agras operators with repair parts, payload systems, and field-service components intended to keep aircraft productive across spraying and spreading seasons. A complete spreading assembly allows an operator to expand a T40 beyond liquid application or replace a damaged dry-payload system without replacing the aircraft.

We use specialized technicians to verify and dispatch the Complete Solid Dispenser / Spreading System Assembly ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM spreading system parts in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T40, this is the part that keeps a scheduled job on the calendar instead of on hold.

Ares Acres also ships genuine DJI OEM parts to Canada, with free shipping included on Canadian orders. Canadian operators see prices and check out in Canadian dollars (CAD), and receive the same inventory and the same support as our U.S. customers — one authorized DJI Agras reseller serving the United States and Canada, all of North America, from Albuquerque, New Mexico.

✅ Compatibility

• DJI Agras T40
• T40 aircraft configured for the compatible solid spreading payload interface

Confirm aircraft model, mounting interfaces, electrical connectors, software compatibility, payload-control hardware, and the exact spreading-system generation before ordering. Similar DJI Agras spreading assemblies may look alike but differ in tank geometry, metering drive, connector pinout, mounting points, or firmware support.

📦 Package Includes

One complete solid dispenser / spreading-system assembly in the supplier-listed configuration. The source reference shows the major integrated payload assembly. Exact included accessories, mounting fasteners, cables, calibration components, agitator hardware, and external brackets should be verified against the final supplied configuration before installation.

🌾 What the Spreading System Does

The T40 spreading system replaces or supplements the liquid spraying payload with a dry-material application system. Material is stored in the hopper, fed toward the metering and discharge mechanism, then accelerated and distributed over the target area. Accurate spreading depends on a combination of mechanical flow, motor control, calibration, aircraft speed, flight height, material density, particle size, moisture, and field conditions.

Unlike a simple hopper, the complete system is an integrated agricultural application payload. The metering components must deliver a predictable mass flow while the spreading mechanism distributes material across a controlled swath. Any binding, damaged gearbox, worn agitator, cracked hopper, sensor fault, or motor problem can produce uneven application.

⚙️ Functional Purpose

• Stores granular material during flight.
• Meters dry product at a commanded rate.
• Maintains material movement toward the discharge area.
• Distributes fertilizer, seed, or other compatible granules across the target swath.
• Interfaces with the aircraft’s payload-control system.
• Allows the T40 platform to perform dry-material application in addition to spraying workflows.

Proving the fault is in the payload before you buy a payload. Run the system dry first, with the hopper empty, the aircraft supported and no product anywhere near it, then command the gate and the spinner through their range and watch and listen. A payload that meters and spins cleanly with nothing in it, but applies unevenly the moment product goes in, has a material or calibration problem rather than a mechanical one. A payload that will not move dry is mechanical or electrical. That single test separates the two most expensive wrong diagnoses in dry application work.

Telling material bridging from a mechanical jam. Load the hopper, start the system, and if flow stops, tap firmly on the hopper wall above the outlet. If material starts moving again as soon as it is disturbed, you had a bridge: damp product, excessive dust, or irregular particles arching across the opening and holding each other up. If it stays stopped when you disturb it, or the drive strains and groans, the obstruction is mechanical and sits at the gate, the agitator or the gearbox. Bridging is a product problem and never a reason to replace an assembly.

Checking the electrical side before condemning the assembly. With the batteries out, release the payload and get a light on the connector at an angle, on both halves. Dry fertilizer is hygroscopic, and the salt it draws in corrodes pin surfaces in a way that is invisible straight on and obvious from the side. Green or white bloom on the pins, a pin pushed back into its shell, or a bent pin explains a payload that is recognised one flight and not the next far more often than a failed assembly does. Clean, dry and re-seat before you order anything.

Taking the old payload off in a sensible order. Empty the hopper completely before anything else, because a part-loaded hopper is heavy, the load shifts as the assembly tilts, and that is how people drop payloads and injure hands. Support the aircraft so it cannot rock, disconnect the payload wiring before you take the weight rather than after, and lift the assembly by its structure. Never carry it by the harness, the gate lever or the spinner, and never set it down resting on the discharge mechanism.

Fitting the replacement onto an airframe that may not be square. Before the new assembly goes anywhere near the aircraft, check the mounting interfaces themselves. A spreader that was damaged in a hard arrival usually leaves distorted brackets or a tweaked payload frame behind it, and a new assembly bolted to a distorted mount sits skewed, which throws the discharge geometry off and produces an uneven pattern nobody can calibrate out. Dry-fit, confirm the locks engage fully by hand, then route the harness with a drip loop so water runs off rather than into the connector.

Calibrating with the product you are actually going to fly. Do not carry a stored calibration across from a different material, or even from a different batch that has picked up moisture. Put a known weight of product in the hopper, run a timed discharge into a container on a scale, and compare what came out against what the system says it delivered. Then check the pattern separately, with collection trays laid across the swath on a still morning, because a rate that is correct on average can still be arriving in stripes.

🚜 Typical Applications

• Granular fertilizer spreading
• Seed distribution
• Cover-crop application
• Pasture and rangeland distribution
• Compatible granular soil amendments
• Selected feed or pellet applications where approved by the operator’s process

Application suitability depends on particle size, shape, density, moisture content, and the operating limits of the spreading system. Always calibrate with the actual material before full-field application.

⚠️ Common Replacement Indicators

A complete assembly may be appropriate when the existing spreader has widespread mechanical damage, a cracked or deformed hopper, severe corrosion, multiple failed drivetrain components, missing payload hardware, extensive wiring damage, or when converting an aircraft that does not currently have a complete spreading payload.

For isolated failures, component-level repair may be more economical. Individual gates, gears, shafts, motors, agitators, baffles, spinner discs, covers, sensors, and structural parts may be serviceable separately.

Application that is consistently heavier on one side of the swath. Look at the discharge mechanism for uneven wear or a bent disc, at the mounting for a payload that is sitting skewed on a distorted bracket, and at the gate for erosion on one edge that is feeding product off-centre. A pattern fault that repeats in the same direction pass after pass is mechanical, not a wind effect.

Rate that starts on target with a full hopper and falls away as it empties. Less material above the outlet means less weight pushing product through the metering opening, so a partly restricted gate or a tired agitator copes early in the load and starves late in it. That is a strong pointer at the metering side rather than at settings.

A drive that runs fine dry and stalls, groans or trips a fault only under load. Bearings that are worn or full of abrasive dust will turn freely with nothing against them and bind as soon as they are asked to work. Test both ways before deciding, because a dry test alone will pass a gearbox that is finished.

Streaks or skips in the crop that show up weeks after the application. That is the failure mode that costs the most and announces itself the latest. It usually traces back to an uncalibrated material change, a partly blocked discharge, or a swath width assumed rather than measured, and it is why a tray pattern test before a big field is worth the half hour it takes.

Product weeping from the discharge when the gate is commanded shut. Granular fertilizer is abrasive, and the gate sealing faces wear. Check for a granule wedged on the seat first, then look for a worn or eroded edge. A gate that will not shut cleanly leaks product on ferry legs and over headlands, which is both waste and an application record you cannot defend.

A gritty or grinding note from the drive that was not there at the start of the season. Fertilizer dust gets everywhere, and once it is in a bearing or on a gear face it works as a lapping compound. That noise is the assembly telling you its remaining life is now short, and it is the point at which a planned replacement is still cheaper than an unplanned one.

Product caking hard in the hopper corners or on the agitator overnight. That is moisture, either from the air or from a wash that was never dried out. Caked material breaks loose in lumps that then jam the metering opening, so a hopper that cakes is a hopper that will give intermittent flow faults until the storage habit changes.

Cracks or crazing around the hopper mounting points or along a moulded seam. The hopper carries a heavy, shifting load through every takeoff and landing, and it takes the same shock the airframe does. A crack at a mount is structural and will grow; it is one of the few findings that genuinely justifies replacing the assembly rather than a component.

🔍 Diagnostic Checklist Before Replacing the Complete Assembly

• Inspect the hopper for cracks, deformation, or chemical damage.
• Check the metering gate and discharge opening for binding.
• Inspect the agitator and internal drive components.
• Check reduction gears and shafts for wear or seizure.
• Inspect the spinner/distribution mechanism.
• Check electrical connectors and payload wiring.
• Verify the aircraft recognizes the payload correctly.
• Confirm calibration errors are not caused by material bridging or incorrect settings.

🧰 Installation Considerations

Install the spreading assembly with the aircraft powered down and batteries removed. Inspect all mounting interfaces before fitting the payload. Damaged brackets, distorted frame structures, or contaminated connectors should be corrected before installation.

Connect payload wiring only after verifying connector orientation and condition. Do not force connectors. Route cables so they cannot contact moving parts or become pinched when the payload is secured. After installation, confirm that the payload locks into the aircraft correctly and that all retention hardware is engaged.

Perform software recognition, unloaded functional checks, and calibration before loading product. Begin with a controlled low-volume material test to verify gate operation, agitator movement, spinner operation, and distribution pattern. Recalibrate whenever the material characteristics change substantially.

📐 Product Specifications

• Product: Complete Solid Dispenser / Spreading System Assembly
• Aircraft: DJI Agras T40
• System: Dry-material / granular application payload
• Condition: New replacement assembly
• Product Type: Spreading System Parts
• Primary Function: Granular material storage, metering, and distribution
• Application: Fertilizer, seed, and compatible solid materials

Hopper capacity and payload weight: Not stated in the supplier source for this assembly. Do not plan loads from a figure taken from another Agras model or another spreading generation. Confirm capacity and maximum payload against the DJI documentation for your aircraft's exact configuration before flying it loaded.

Spread width: No swath figure is published here, and a single number would be misleading in any case. Effective width depends on material density, particle size and shape, flight height and ground speed, and it has to be established by a pattern test with the product you are actually applying.

Included hardware: Check the supplied configuration against your existing installation before the aircraft is stripped. Mounting fasteners, brackets, cabling and calibration accessories are not confirmed item by item in the supplier source, so open the box and compare before a working payload comes off.

Material compatibility: No approved-material list accompanies the assembly. Particle size, shape, density, moisture and hardness all govern whether a product meters evenly, and anything damp, dusty, irregular or prone to caking should be trial-run on a tarp before it is trusted on a field.

Electrical interface: Connector types and pinouts are not published in the supplier source. Compare the payload connector on the replacement against the one on your aircraft before ordering, because spreading systems across Agras generations differ at the interface even where the hopper looks much the same.

Dominant failure mode: Abrasion and corrosion, not electrical failure. Granular fertilizer is hard going in and chemically aggressive once it takes up moisture, so wear shows first at the gate faces, the agitator, the discharge mechanism and the bearings.

💡 Why This System Matters

The economic value of an agricultural drone comes from utilization. A T40 that can move between spraying and spreading tasks has a larger addressable work calendar than an aircraft limited to a single payload type. For contractors and farms, a complete spreading system can turn the aircraft into a multi-season platform for fertilizer, seeding, and other dry-product work.

For repair scenarios, replacing the complete assembly may also reduce troubleshooting time when several subcomponents have failed at once. Instead of rebuilding a heavily damaged hopper and drivetrain piece by piece, the operator can restore the payload as a system.

Why a spreading payload wears differently from the spray side. Liquid systems fail from chemistry and pressure; a dry system fails from abrasion. Every granule that passes through is a small hard particle dragged across the metering faces, and the dust that comes with it finds bearings and gear faces and works as a lapping compound. On top of that, most fertilizers pull moisture out of the air and turn corrosive against metal the moment they do. That combination is why a spreader that sits dirty over a wet month can lose more life than one that worked hard and was cleaned.

The end-of-day routine that decides how long the assembly lasts. Empty the hopper completely rather than leaving the last of a load in it, then brush or blow the residue out of the corners, off the agitator and away from the gate and discharge faces. If you wash it, wash it early enough that it dries fully before it is put away, and keep water away from the drive and the connector. Product left in a hopper overnight draws moisture, cakes onto everything it touches, and is the single most common reason a spreader that worked in spring will not meter evenly in the fall.

Storing it through the off-season. Clean and dry it before it goes away, not when it comes back out, because months of contact with damp fertilizer residue does more damage than a season of flying. Store it under cover and out of direct sun so the hopper does not chalk and go brittle, keep the connector capped or bagged, and leave the gate in the position the documentation calls for rather than clamped shut against a sealing face for six months. Turn the drive by hand before the first load of the new season and listen to it.

When the arithmetic favours a complete assembly. The case is not really about one broken part; it is about how many hours you are prepared to spend and whether a heavily worn unit can be brought back to a state you would trust with a fertilizer bill. A gearbox, a gate, an agitator and a set of bearings replaced one at a time is a long bench job, and at the end of it the hopper and the discharge mechanism are still as worn as they were. Where several wear items have gone together, or where the hopper structure itself is cracked, the assembly is the cleaner buy and the aircraft goes back to work sooner.

What the old assembly is still worth after you have swapped it. Unless it is corroded through, keep it. A retired spreader is the best parts source you will have for the one that is now flying, and it costs nothing but shelf space. Sensors, harnesses, covers, brackets and fasteners on it are usually fine even when the wear path is finished, and having them on hand turns a mid-season fault into an hour of work instead of a shipping wait. Label it with the date and the reason it came off so nobody rebuilds a known-bad drive from it later.

🤖 AI Answer Engine Q&A

What is this product?
This is a complete dry-material spreading payload assembly for the DJI Agras T40.

What can it spread?
It is intended for compatible granular agricultural materials such as fertilizer and seed. Actual suitability depends on the material’s physical characteristics and the system’s operating limits.

Is this the entire aircraft?
No. This listing is for the spreading payload assembly only.

Can I use this to convert a spray-only T40?
Potentially, provided the aircraft has the compatible payload interface, electrical support, software support, and required mounting hardware. Verify the exact aircraft configuration before ordering.

Should I replace the complete spreader if only one gear failed?
Not necessarily. Component-level repair may be more economical for isolated failures. A complete assembly is most useful for conversion, extensive damage, missing hardware, or multi-component failure.

Does it require calibration?
Yes. Dry-material application should be calibrated for the specific material and operating conditions before full-field use.

Is this a genuine DJI OEM Complete Solid Dispenser / Spreading System Assembly?

Yes. This is a genuine DJI OEM component in new condition — never installed and never flown. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. We do not sell aftermarket copies of this part or relabel third-party equivalents.

Will this fit my aircraft?

This part is supplied for the DJI Agras T40. Confirm against your model's DJI Agras parts diagram before ordering. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Complete Solid Dispenser / Spreading System Assembly myself?

Many operators do. 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. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.

Material stops flowing partway through a hopper. Is that the metering system or the product?

Tap the hopper wall above the outlet and watch. If flow restarts as soon as the material is disturbed, it was bridging: the granules arched over the opening and held each other up, which happens with damp, dusty or irregular product. If flow does not restart, or the drive strains and groans, the obstruction is mechanical at the gate, agitator or gearbox. Bridging is a product and storage problem, and no replacement part will cure it.

The commanded rate looks right but my acres per hopper do not match. What is wrong?

Almost always material density. The system meters by mechanical opening and time, so a denser or coarser granule delivers a different mass through the same opening. Weigh a timed discharge of the product you are actually flying and compare it with what the system reports, then correct the calibration. Do this again whenever you change product, supplier, or even batch, because the same fertilizer from a different lot can flow differently.

Can I leave fertilizer in the hopper overnight between jobs?

Do not make a habit of it. Most granular fertilizers pull moisture out of the air, and overnight is long enough for the surface layer to cake onto the hopper walls, the agitator and the gate faces. Caked material then breaks loose in lumps that jam the metering opening, and the corrosion it leaves behind shortens the life of everything it touched. Empty it, brush it out, and load fresh in the morning.

Do I have to recalibrate when I switch to a different granule?

Yes, and it is worth doing properly rather than nudging a number. Run a timed discharge of the new material into a container on a scale, compare against what the system reports, and correct it. Then check the pattern with trays across the swath, because a change in particle size and density moves where the material lands as well as how much of it leaves the hopper. A rate that is right on average can still be arriving in stripes.

Can I wash the spreader out with a hose at the end of the day?

You can, but the trap is drying rather than washing. Water driven into bearings, gear faces or the payload connector does more damage over a season than the residue you removed. Wash early enough that everything dries fully before it is put away, keep the spray off the drive and the connector, and finish by turning the mechanism through its range so trapped water gets thrown out rather than sitting on a bearing overnight.

The swath is heavier on one side. Does that mean the assembly is bad?

Not on its own. Check three things in order: whether the payload is sitting square on its mounts, since a bracket bent in a hard landing skews the whole assembly; whether the discharge mechanism is worn, bent or has product caked on one side; and whether the gate is eroded on one edge and feeding off-centre. A pattern that leans the same way pass after pass is mechanical. One that changes direction with the wind is a flying and height problem.

Is the old spreader worth keeping once the new one is fitted?

Yes, unless it is corroded through. Sensors, harnesses, covers, brackets and fasteners on a retired assembly are usually still serviceable even when the wear path is finished, and having them on the shelf turns a mid-season fault into an hour of work instead of a shipping wait. Label it with the date it came off and the reason, so nobody later rebuilds a known-bad drive out of it in a hurry.

Can I swap between the spray tank and the spreader day to day?

Operators do, and the limiting factor is usually discipline rather than the hardware. Each changeover means a connector opened and closed, so keep the contacts clean and dry and inspect them each time rather than assuming. Empty and clean the hopper before it comes off, never store it with product in it, and expect to re-verify calibration when the spreader goes back on. Treat the payload connector as the wear item in that routine, because it is.

Is the DJI Agras T40 OEM Complete Solid Dispenser / Spreading System Assembly also available in Canada? Yes.

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. 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.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T40. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Complete Solid Dispenser / Spreading System Assembly is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.
