🔧 Component Overview

The DJI Agras T100 OEM Auger Motor Cover is the OEM auger motor cover fitted to the spreading auger and boom assembly of the DJI Agras T100, responsible for feeding granular material from the spread tank to the spinner at a controlled rate.

Feeding granular material from the spread tank to the spinner at a controlled rate is the job description for the spreading auger and boom assembly, and this module is part of how it gets done. The T100 is a working machine — it earns its keep in fill-and-fly cycles, not hangar hours — and every component in the spreading auger and boom assembly is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside Auger Motor, Screw (M40-HC01200120-072040-5103-Y), Screw (M25-HCW00960040-055020-5103-Y).

Ignore a failing auger motor cover and the bill compounds: downtime in the middle of an application window, collateral wear on the parts around it, and jobs that slip to a competitor while the aircraft sits. Replacing it costs a part; not replacing it costs acres. That trade only runs one direction.

For professional farmers, aerial applicators, and commercial drone operators, this module is how the spreading auger and boom assembly stays field-ready instead of becoming the reason the aircraft sits.

This is a working part on a working aircraft.

The auger motor cover handles:

• Performing its designed role within the spreading auger and boom assembly every second the aircraft operates
• Interfacing with the surrounding spreading system components exactly as the factory architecture intends
• Maintaining stable operation across the full temperature range of a working day
• Surviving the vibration environment of a heavy-lift multirotor at working power
• Reporting its status to the flight system so faults surface as errors, not surprises
• Holding calibration and performance over a full season of duty
• Sealing its electronics against spray drift, dust, and washdown exposure
• Restoring factory behavior the moment a worn unit is swapped out

The T100 works brutally hard for its living, including:

• Feeding granular material from the spread tank to the spinner at a controlled rate
• Dawn-to-dusk spray campaigns during narrow application windows
• Repeated fill-fly-return cycles with minutes on the ground between loads
• Full-payload takeoffs from field edges, dozens of times per day
• Chemical exposure from fungicides, herbicides, insecticides, and foliar fertilizers
• Pressure-washer rinse-downs at the end of every spray day
• Vibration from eight propulsion motors running at working power
• Transport bouncing on trailers and truck beds between fields
• Temperature swings from cold morning starts to full-sun afternoons

What attacks this module in the field:

• Continuous vibration transmitted from the propulsion system
• Thermal cycling from cold starts to full-load afternoons
• Moisture ingress pressure from spray drift and washdowns
• Chemical-laden dust settling on housings and connectors
• Voltage transients during battery hot-swaps
• Connector fretting from repeated maintenance access
• UV exposure degrading housings over seasons
• Shock loads from firm landings on rough ground

That duty cycle is exactly what retires this module. None of these stresses is dramatic on its own — the accumulation is what does it. This is why spreading system modules are inspection items every time the spreading auger and boom assembly is opened up, and why operators who run hard keep spares on the shelf.

A healthy auger motor cover delivers:

• Factory-correct fit in the spreading auger and boom assembly — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored performance you can verify on the first post-repair flight
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Stock the auger motor cover before the season does its work, and the spreading auger and boom assembly never becomes the reason the aircraft sits.

Confirm the cover is the fault and not the motor behind it, because the two produce completely different evidence. A cover that has failed does not stop the auger turning or change the rate the aircraft meters; what it does is stop keeping granular material, dust and water off the drive it shields. So a stall, a rate that will not hold, or a spreader that reports a drive fault is a motor, coupling or metering problem. The cover's case is made by what you find underneath it: prill dust packed around the motor body, damp caked fertilizer sitting against the shaft area, or corrosion on hardware that should be dry.

Read the dust track around the sealing line before you clean anything off. Take the cover away and look at the joint face on both halves under a light. A joint that has been sealing leaves a clean sharp edge where the dust stops. A joint that has been passing material leaves a feathered track of fine prill dust running inboard from the flange, usually heaviest at one corner or beside one fastener. That track points straight at where the seal is being lost, and it tells you whether the cover has warped, a boss has crushed, or a fastener has been running loose.

Check the inside of the cover for thinning rather than only for cracks. Granular fertilizer is abrasive, and where it circulates against the inner face it polishes the surface and slowly takes material away. Look for an area that is noticeably glossier than the rest, then press it with a thumb and compare the flex against a section away from the wear. A cover that has gone thin will crack there without warning, and it will do it in service with the tank loaded rather than on the bench where you would find it.

Tell impact damage apart from chemical and UV degradation, because they mean different things about the rest of the aircraft. An impact crack radiates from one point, has clean edges, and the material either side of it is still the right color and still flexes normally. Degradation shows as a whole surface that has gone chalky, faded and dry to the touch, and the part breaks in an irregular crumbly way rather than along a line. Impact means you replace one cover. Degradation means every polymer part of the same age on that assembly is in the same condition and should be inspected now.

⚙️ Functional Purpose

The auger motor cover is designed to do one job in the spreading auger and boom assembly and do it to specification: feeding granular material from the spread tank to the spinner at a controlled rate.

The module:

• Serves the spreading auger and boom assembly of the DJI Agras T100 exactly as the factory intends
• Supports feeding granular material from the spread tank to the spinner at a controlled rate
• Maintains the tolerances and interfaces the surrounding parts depend on
• Withstands the chemical, vibration, and washdown environment of agricultural work
• Preserves the sealing and protection strategy of the platform
• Keeps failure modes visible and diagnosable instead of mysterious
• Restores factory behavior immediately upon correct installation
• Protects the more expensive components it works alongside
• Carries the exact DJI specification for its position
• Supports safe, predictable operation under full payload
• Eliminates the guesswork of near-fit substitutes
• Keeps the aircraft inside its designed maintenance program
• Holds up across a full season of professional duty

Function on the T100 is a chain: spreading system performance depends on the spreading auger and boom assembly, and the spreading auger and boom assembly depends on every part in it holding specification. This module is one link in that chain — and chains fail at the worn link, not the average one.

That is why the platform's maintenance philosophy is inspection and renewal, not run-to-failure. The operators with the best uptime records are not the ones with the newest aircraft — they are the ones who replace parts like this when inspection says so, on their own schedule instead of the failure's.

A failing auger motor cover costs you:

• Downtime in the middle of an application window — the most expensive hours in agriculture
• Acres not covered while the aircraft waits on a part
• Collateral wear on the components around the failing one
• Diagnostic hours chasing symptoms instead of causes
• Rework when a temporary fix lets go mid-job
• Customer trust when scheduled work slips
• Higher repair bills the longer the fault runs
• Risk exposure every flight the fault remains aboard
• Resale value on an airframe with deferred maintenance

Fix it on your schedule, not the failure's.

Empty and clean out the spreading system before the cover comes off. Run the tank down, clear the auger tube, and get the residual granular material out rather than discovering it on the shop floor. Dry prill pours; damp prill has already set into a crust that will have to be broken loose, and breaking it loose with the cover in place drives grit into exactly the interfaces you are trying to protect. Rinse and dry the outside of the assembly too, so what is sitting on top of the cover does not fall into the motor as you lift it away.

Blow or vacuum the area down before you loosen a single fastener, not after. Fertilizer dust collects in every ledge around a spreading assembly, and the moment the cover breaks its seal, everything that was resting on it goes straight into the motor, the shaft area and the fastener holes. Two minutes with a vacuum nozzle before disassembly saves a much longer and much less thorough clean-up afterwards, and it is the difference between fitting a new cover onto a clean joint and sealing contamination inside.

Record the fasteners by position, because covers rarely use one length throughout. Lay them out in the pattern they came from or push them through a piece of card marked with the layout. A fastener that is a few millimeters too long in the wrong hole either bottoms out and never clamps the cover, which leaves you with a joint that leaks and no obvious reason why, or it reaches something behind the cover that it was never meant to touch. Note any that were fitted with a washer or a sealing collar and which way that faced.

Do not lever the cover off against the boom tube, the motor end or the tank. If it is stuck it is stuck on cured residue rather than on anything mechanical, so free it by working around the joint with steady hand pressure, or tap a soft block against a solid rib on the cover itself. A screwdriver blade in the joint concentrates your whole effort on the sealing face, and the sealing face is the one feature on the assembly that has to be right for the new part to do its job.

Clean both sealing faces to bare, dry material before the new cover goes on, then fit it without forcing anything. Scrape and wipe the flange on the assembly as well as the new cover, because a ridge of hardened fertilizer only a fraction of a millimeter thick holds the cover off its seat and the joint then clamps on a high spot. Start every fastener by hand, bring them up in a cross pattern in two passes to the DJI torque value, and check the cover sits down evenly all the way round with no gap at any corner. Then run the spreader dry and listen before you put material in it.

⚠️ Common Replacement Indicators

• Error messages or warnings referencing this system in the app
• Intermittent operation that worsens with temperature or vibration
• Function loss in the system this module serves
• Visible corrosion, moisture, or chemical residue at connectors
• Physical damage to the housing after an impact
• Erratic readings or behavior the aircraft cannot self-clear
• Failures that appear under load but pass on the bench
• Burnt smell or discoloration at the module
• Repeated faults after connector reseating
• Function dropouts during arm fold or unfold
• Behavior that started after a hard landing or transport
• Age and hours — electronics in this environment are not lifetime parts

What kills spreading system modules: the compounding of ordinary duty. Chemical exposure attacks materials, vibration works at every interface, UV ages every exposed surface, and washdowns drive water at every seam — repeated across hundreds of cycles per season. Add the occasional hard landing or transport knock and the result is predictable: the part that was fine in spring is the failure point by late season.

Replacement and verification: Replacement is a standard shop task on the T100: open access to the spreading auger and boom assembly, document connections and hardware positions, swap the auger motor cover for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work, and confirm system behavior in the app where applicable.

Confirm before you order: this is DJI part YC.JG.ZS006137. Check the label on your old auger motor cover or the position in your official parts diagram and match the number — revision suffixes like .01 or .F on a label are the same part.

Fine fertilizer dust building up inside the cover between services: the seal path has been compromised somewhere. It does not take a visible crack, and it usually is not one. Look for a fastener that has been running loose, a mounting boss that has crushed under overtightening, a warped flange that no longer sits flat, or a sealing element that has taken a compression set. Dust getting in is the early warning, and it arrives well before moisture does.

A crust or cake of set fertilizer on the motor body or around the shaft area: moisture has been getting in and staying in. Granular fertilizer is hygroscopic, so it pulls water out of the air and holds it against whatever it is sitting on, which means a small leak in this cover produces a damp corrosive poultice that never dries out under there. This is the failure that costs real money, because by the time you see the cake, the hardware and the motor housing underneath it have been wet for weeks.

A tick, rub or scraping sound from the auger motor area that changes with auger speed rather than with rotor speed: something is contacting a rotating part. A cover that has warped from heat, been distorted by an overtightened fastener, or been knocked in transport can move enough to touch the drive. Shut down before running it further. A cover that is rubbing is also wearing itself through, and the debris goes into the drive.

Fasteners at this cover that keep backing out while the rest of the assembly holds: the cover is not clamping properly, so the joint is moving and shaking the fastener loose. Retightening treats the symptom. Look for a mounting boss that has crushed or crazed, a flange that has warped so it only touches at two points, or a fastener that is bottoming in its hole because it is the wrong length or was fitted to the wrong position at the last service.

A surface that has gone chalky, faded and dry across the whole cover: UV and chemical exposure have degraded the resin at the surface. The part can still be the right shape and still be structurally finished, because degraded polymer loses toughness before it loses geometry and then breaks without bending first. This is a replace-now finding rather than a watch item, and it is also a prompt to look at every other polymer part of the same age on the spreading system.

Dimensions, Weight and Material: Not published in this listing. Compare the replacement against the cover you removed for overall size, flange shape, fastener hole pattern and the position of any cutout or relief before fitting, and confirm the position on the official DJI Agras T100 parts diagram.

Fastener Torque: Not published here. Use the DJI service value for the hardware at this position with a calibrated driver. Cover fasteners are the ones most often overtightened by feel, and a crushed mounting boss is the most common reason a replacement cover leaks from the day it is fitted.

Gaskets, Seals and Fasteners: The listing supplies the cover. Any gasket, sealing element, fastener or washer that your assembly uses is not itemized here, so inspect what you remove and order those separately by their own DJI material numbers if they are hardened, split, flattened or corroded.

Repairability: None worth attempting. Tape, sealant and adhesive on a cover that lives against abrasive granular material and gets washed down will let go, and it will let go without telling you. The cost of the failure is measured in what gets into the drive underneath, not in the cover.

🚜 Necessary For

Built for:

• Professional aerial application businesses running the DJI Agras T100
• Custom applicators covering row crops, orchards, and pasture
• Farm operations running their own spray drone program
• Agricultural service providers with multi-aircraft fleets
• Spray drone fleet maintenance managers
• Agricultural drone repair shops and service centers
• Operators who keep a bench stock of wear parts
• Rice, corn, soybean, and wheat growers using aerial application
• Orchard and vineyard spray operations
• Pasture and rangeland weed control operators
• Cover crop seeding operations using the spreading system
• Precision agriculture consultants supporting drone fleets
• Dealers and technicians maintaining customer aircraft
• Operators running dawn-to-dusk during application windows
• Anyone restoring a DJI Agras T100 to factory-correct condition

Especially valuable during:

• Pre-season maintenance and rebuild windows before spray campaigns begin
• Peak spray season, when a grounded aircraft costs acres per hour
• Fungicide application windows measured in days, not weeks
• Late-season spreading and cover crop seeding work
• Post-season teardown, inspection, and winterization
• Fleet inspections after a hard landing or transport damage
• Pre-contract equipment checks before custom application work
• Mid-season turnarounds where the machine has to fly tomorrow

If the DJI Agras T100 earns its keep on your operation, this module belongs on your parts shelf before it belongs on your aircraft. The time to buy it is before the season, not during the failure.

Distinguish this cover from the other covers and shrouds on the spreading system by the features that carry function rather than by shape. Lay the removed part on the replacement and check the fastener hole pattern first, then the outline and position of any cutout for a shaft or tube, then which side any drain, vent or relief falls on, then the depth of the flange. Covers on a spreading assembly are deliberately similar in appearance and differ in exactly those details, so match DJI material number YC.JG.ZS006137 and confirm the position rather than trusting a photograph.

Inspect the drive this cover was protecting while you have access to it, because that is the whole reason the part exists. Look at the motor housing and its hardware for corrosion, staining or a white bloom, check the shaft area for packed material and for a seal that has hardened or lifted, rock the shaft gently and feel for play or roughness that was not there before, and look for heat discoloration. Check the connector and its seal, and look along any wiring that runs past or clips to the cover for a rub mark or a flattened jacket.

If this cover was cracked by an impact rather than by wear, keep looking outward before you close the assembly up. Check the boom and its mounting on that side, the spinner assembly and its guard, the tube clamps, and the fasteners on adjacent parts. Something struck the aircraft hard enough to break a cover, and the parts nearby will usually show quieter evidence, such as a hairline crack at a boss, a clamp that has shifted on the tube, or a fastener that is no longer tight.

💡 Why This Part Matters

Every acre the T100 covers depends on the spreading auger and boom assembly doing its job — and the spreading auger and boom assembly depends on parts exactly like this one.

The economics are simple. The DJI Agras T100 exists to cover ground during windows that do not wait — and every hour it sits, the work either doesn't happen or happens on someone else's schedule. A failed auger motor cover is rarely expensive because of what the part costs; it is expensive because of when it fails. Parts fail during use, and use happens during the season.

That is the case for OEM and the case for stocking ahead. The OEM module fits the first time, behaves the way the platform expects, and carries the exact specification the spreading system was engineered around — DJI material number YC.JG.ZS006137. No adaptation, no surprises, no second teardown to undo a near-fit part.

This module delivers:

• Factory-correct fit in the spreading auger and boom assembly — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored performance you can verify on the first post-repair flight
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Running a compromised auger motor cover, operators risk:

• Mid-job failure during an application window
• Collateral damage to surrounding components
• Chasing intermittent symptoms across the whole system
• Alignment and fit problems spreading to adjacent parts
• Unplanned grounding with the fleet committed to jobs
• Warranty and service complications from improvised fixes
• Higher lifetime cost from deferred maintenance
• An aircraft that cannot be trusted at full payload

Diagnose it fast. Swap it clean. Verify it flying. Keep the acres moving.

Ares Acres stocks the auger motor cover in the USA with free, fast shipping — so the day you need one is the day it ships, not the week you wait.

Granular fertilizer is the hardest thing this aircraft carries, and the cover exists specifically because of it. Prill is abrasive on the way through and hygroscopic once it settles, which means any dust that gets past a sealing face draws moisture out of the air and holds it there as a damp corrosive paste. Under a cover it stays wet long after the outside of the aircraft is dry, and it works on hardware and housings around the clock rather than only while the aircraft is flying. Clear the system out at the end of a spreading day rather than leaving it loaded overnight.

Keep the pressure washer off the cover joint. Blasting a sealing face is the fastest way to put water exactly where the cover is meant to keep it out, and repeated high pressure on a polymer surface erodes the resin and accelerates the chalking that ends the part's life. Wash the assembly at low pressure with a brush, direct water away from the joint rather than into it, and let the aircraft dry properly before it goes into a closed trailer where any moisture that did get in will stay.

Treat this as a sealing part with a silent failure mode, and replace it on condition rather than waiting for it to break. A cover that is chalky, that has a flange which no longer sits flat, that has a polished thin patch inside, or that has a crushed fastener boss has already stopped doing its job even though it is still in one piece and still bolted on. Nothing warns you: the aircraft flies normally, the spreader meters normally, and the damage accumulates on the drive underneath until that is the part you are buying instead. Handle the replacement carefully too, keeping it bagged and out of the sun and keeping the sealing face unscratched until it goes on.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 Auger Motor Cover? It is the OEM auger motor cover serving the spreading auger and boom assembly of the DJI Agras T100. It is the genuine DJI Agras component for this position, supplied new.

What is the DJI material number (part number) for the Auger Motor Cover? The DJI material number is YC.JG.ZS006137, listed on the official DJI Agras T100 parts breakdown. Labels sometimes carry a revision suffix such as .01 or .F — that is the same part; match the base number.

Which DJI Agras models does this module fit? Supplier-listed fitment is DJI Agras T100. Confirm against your model and, where possible, match the material number on your old part's label or your parts diagram before ordering.

How do I know my auger motor cover needs replacing? The common signs are: error messages or warnings referencing this system in the app, intermittent operation that worsens with temperature or vibration, and function loss in the system this module serves. Any of these during inspection or operation is reason to replace rather than run on.

What causes this module to fail? Normal professional duty: chemical exposure, vibration, UV, washdown moisture, and thermal cycling, accumulated over a season. Hard landings and transport knocks accelerate all of it.

How do I confirm the diagnosis before ordering? Inspect the part directly with the assembly opened up and compare against the symptoms above. Match the label on the old part to material number YC.JG.ZS006137 to confirm you are ordering the exact position. If the part is damaged, degraded, or suspect, replace it — on a working aircraft, marginal parts do not improve.

What does installation and verification look like? Replacement is a standard shop task on the T100: open access to the spreading auger and boom assembly, document connections and hardware positions, swap the auger motor cover for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work, and confirm system behavior in the app where applicable.

What other parts should I inspect at the same time? On the official diagram this part sits alongside Auger Motor, Screw (M40-HC01200120-072040-5103-Y), Screw (M25-HCW00960040-055020-5103-Y). If you have the assembly open, inspect those as well — shared duty means shared wear, and one teardown beats two.

My auger stalls and the spread rate will not hold. Will a new cover fix that?

No, and it is worth being clear about why. The cover is a protective enclosure at the auger drive, so it does not turn the auger or meter the material. Metering and stall faults belong to the drive, the coupling, the metering hardware or the material itself, and bridging or damp caked product in the tank is a very common cause. What the cover is responsible for is what you find when you remove it: dust packed around the drive, damp fertilizer against the shaft area, or corrosion on hardware that should be dry.

The cover is faded and chalky but it is not cracked. Should I replace it?

Yes. A chalky, faded, dry surface means UV and chemical exposure have broken the resin down, and degraded polymer loses toughness well before it loses shape. That is a part which will break without bending first, most likely with the tank loaded and in the middle of a job rather than on your bench. It is also a signal about everything else: any other polymer part of the same age on the spreading system has had the same exposure and should be inspected while you are there.

Can I run the spreader with the cover cracked or off until the replacement arrives?

It is not worth it. The cover exists to keep abrasive prill dust and the moisture it attracts off the drive underneath, and a spreading system with that protection missing puts hygroscopic material straight against hardware and housings that stay damp long after the outside dries. A day of that can cost you the assembly the cover was protecting, which is an order of magnitude more part and more labor. Tape and sealant do not survive the abrasion and washdown either.

There is no visible crack, so how do I tell whether the cover has been leaking?

Look at the dust track around the sealing line before you clean the joint. Where a joint has sealed, the dust stops at a clean sharp edge. Where it has been passing material, you get a feathered track of fine prill dust running inboard from the flange, usually worst at one corner or beside one fastener, and that tells you where the seal is being lost. Then check that spot for a crushed mounting boss, a warped flange that only touches at two points, or a fastener that has been running loose.

What should I inspect on the drive while the cover is off?

Everything the cover was there to protect. Check the motor housing and its hardware for corrosion, staining or white bloom, look at the shaft area for packed material and for a seal that has hardened or lifted, rock the shaft gently and feel for play or roughness, and look for heat discoloration on the housing.
