🔧 Component Overview

The DJI Agras T100 OEM Spray Lance Shaft is the OEM spray lance shaft in the mist spray lance of the DJI Agras T100, part of the structure carrying atomized spray hardware into the airflow beneath the rotors.

Carrying atomized spray hardware into the airflow beneath the rotors is the job description for the mist spray lance, and this component 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 mist spray lance is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside Mist Sprinkler Support Rod, Mist Spray Lance Connector, Centrifugal Sprinkler Adapter Cable (Optional).

Ignore a failing spray lance shaft 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 component is how the mist spray lance stays field-ready instead of becoming the reason the aircraft sits.

This is a working part on a working aircraft.

The T100 works brutally hard for its living, including:

• Carrying atomized spray hardware into the airflow beneath the rotors
• 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 component in the field:

• Vibration from the propulsion system every flight hour
• Chemical exposure from spray drift and washdown
• UV degradation across a season outdoors
• Shock loads from field-edge landings
• Grit and dust working into interfaces
• Thermal cycling from dawn starts to afternoon heat
• Stress concentration at mounting points
• Wear from repeated maintenance access

That duty cycle is exactly what retires this component. None of these stresses is dramatic on its own — the accumulation is what does it. This is why structural and mounting parts are inspection items every time the mist spray lance is opened up, and why operators who run hard keep spares on the shelf.

A healthy spray lance shaft delivers:

• Factory-correct fit in the mist spray lance — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• 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 spray lance shaft before the season does its work, and the mist spray lance never becomes the reason the aircraft sits.

The lance shaft is a cantilever with a spinning weight on the end of it, and that one sentence explains most of what goes wrong with it. The atomizer hangs out at the far end where there is nothing to brace it, the whole assembly sits in the fastest air the aircraft makes, and every gram of imbalance in the atomizer head is fed back into the shaft as a cyclic bending load for as long as the rotors are turning. Everything else on the lance bolts to this part or is positioned by it.

Because it is a cantilever, the load is not spread evenly along the shaft. Bending moment is highest at the root, where the shaft is clamped or landed into the Mist Spray Lance Connector, and it falls away to almost nothing at the atomizer end. That means the part fails at the root far more often than anywhere else, and it means an inspection that concentrates on the pretty middle section of the shaft is looking in the wrong place. Clean the root and inspect that.

Most lance shafts are not killed in the air. They are killed on the ground, because a slender arm sticking out from the airframe is the part that catches a tailgate, a barn doorway, a trailer rail, a strap ratchet, or a net. Damage from a ground strike often looks trivial and is not: a shaft that has been loaded sideways once may still measure straight while having moved in its clamp, which is enough to change where the atomizer sits in the downwash.

⚙️ Functional Purpose

The spray lance shaft is designed to do one job in the mist spray lance and do it to specification: carrying atomized spray hardware into the airflow beneath the rotors.

The component:

• Serves the mist spray lance of the DJI Agras T100 exactly as the factory intends
• Supports carrying atomized spray hardware into the airflow beneath the rotors
• 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: atomized spray system performance depends on the mist spray lance, and the mist spray lance depends on every part in it holding specification. This component 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 spray lance shaft 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.

This part does not just hold the atomizer up. It holds it in a specific place and at a specific angle relative to the rotor wash, and the spray system was calibrated around that geometry. Move the atomizer a few degrees or a small distance and the droplets leave into different air than they were meant to, which changes where they land and how far they carry. That is why a shaft problem shows up as a coverage complaint long before it shows up as a broken part.

The second job is holding position against a load that never stops changing. Rotor wash is not steady air. It pulses at blade-passing frequency, it changes with collective and with forward speed, and the aircraft flies in and out of its own wake on every turn at the end of a pass. The shaft is what keeps the atomizer from riding those changes, and a shaft that has loosened at the root stops damping and starts amplifying them.

Third, the shaft is the routing spine for everything else on the lance. The fluid line runs along it, the Centrifugal Sprinkler Adapter Cable runs along it where that option is fitted, and the Mist Sprinkler Support Rod triangulates against it. Those parts are all positioned relative to the shaft, so when the shaft moves or is refitted at a different depth or rotation, the hose gets pulled tight, the cable gets strained, and the brace no longer sits square.

⚠️ Common Replacement Indicators

• Visible cracking, deformation, or impact damage
• Stress-whitening at load points
• Loose fit where the part should seat firmly
• Movement or rattle the design does not allow
• Wear marks from parts contacting where they should not
• Fastener holes elongated or damaged
• Chemical or UV degradation of the material
• Damage found during teardown of the assembly
• Misalignment of the components this part positions
• Noise or vibration traced to this position
• Damage after a hard landing or transport strike
• Previous field repair with tape, glue, or improvisation

What kills structural and mounting parts: 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 mist spray lance, document connections and hardware positions, swap the spray lance shaft 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.

Confirm before you order: this is DJI part YC.JG.QX004533. Check the label on your old spray lance shaft 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.

One side of the swath is consistently heavier or lighter than the other and the nozzles test clean. Before you chase flow, check geometry. Stand behind the aircraft with the lances level and compare the two atomizer heads against a fixed feature of the airframe on each side. A shaft that has drooped, twisted in its clamp, or taken a set aims its atomizer into different air than its partner, and that is a coverage fault no calibration will correct.

Play at the root when you grip the atomizer end. With the aircraft shut down, hold the head and load the shaft gently in each direction. What you want is even elastic flex along the length that returns cleanly. What you do not want is a distinct click, knock, or movement concentrated at the clamped end, because that is the joint moving rather than the shaft flexing, and it will only get worse from there.

Grey or black powder, or a bright polished ring, at the clamped root. That is fretting debris from a joint that has been micro-moving rather than clamping. It matters more here than almost anywhere else on the aircraft, because fretting at the exact point of maximum bending stress removes material where the part can least afford to lose it and leaves a surface that cracks start from.

The atomizer head wobbles or the lance buzzes at one particular rotor setting. Run it up on the stand and note whether the vibration appears at a specific power setting and disappears above and below it. That behavior is resonance, and it means the assembly's stiffness has changed, either because the root joint has loosened or because the shaft itself has been damaged. A wobble present at all settings is more likely the atomizer or its balance.

Chafe marks, a pulled-tight hose, or a strained cable along the shaft after a lance has been off and back on. This is a refit error, not a wear item. It means the shaft went back in at a different rotation or a different depth than it came out, so everything routed along it is now the wrong length. Left alone it wears through a spray line or a sensor cable in short order.

Any hairline mark, dent, crease, or crushed spot found at the root, plus anything at all found after a ground strike. Clean the area, dry it, and look at it under strong light held almost parallel to the surface, which is what makes a fine crack or a raised lip show up. On a cantilever loaded at the root, a mark there is not cosmetic. Treat it as a condemned part until an inspection proves otherwise.

Condition: Brand new

Shaft length, diameter, and material: The DJI parts breakdown does not publish the length, outside diameter, wall thickness, or the material and grade of this shaft, and this listing does not carry those figures. Do not order from a photograph or from a measurement taken off another aircraft. Match DJI material number YC.JG.QX004533 to the Mist Spray Lance sheet of your parts diagram, and compare the new shaft against the removed one before anything gets clamped up.

Clamp or root fastener torque: No tightening figure is published for the joint at the root of this shaft. Use the value in the DJI service documentation for your airframe, and do not settle it by feel. Over-tightening a slender shaft at the clamp squeezes the section out of round and is the usual reason a root joint starts working loose again a few flights later.

Left and right hand fitment: The parts breakdown reproduced here lists this component by material number and position without stating whether the left and right lances take the same part. Do not assume they are interchangeable and do not assume they differ. Check the number on the shaft you removed, and note which side it came off before it leaves the aircraft.

🚜 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

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 component belongs on your parts shelf before it belongs on your aircraft. The time to buy it is before the season, not during the failure.

Operators who transport with the lances fitted. The shaft is the part of the aircraft most likely to meet something solid on the way to the field, and the strikes that do the damage are the slow ones nobody logs: easing through a shed door, backing a trailer past a post, dropping a tailgate. If your machine travels assembled, a spare shaft on the shelf is the difference between a morning of work and a week of waiting.

Anyone chasing a spray pattern fault they cannot explain. When the nozzles check clean, the pump holds rate, and one side of the swath is still wrong, the geometry holding the atomizer is the next place to look. Having the correct shaft in stock lets you settle that question by fitting a known-good part rather than by staring at a suspect one and talking yourself into it being fine.

💡 Why This Part Matters

Every acre the T100 covers depends on the mist spray lance doing its job — and the mist spray lance 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 spray lance shaft 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 component fits the first time, behaves the way the platform expects, and carries the exact specification the atomized spray system was engineered around — DJI material number YC.JG.QX004533. No adaptation, no surprises, no second teardown to undo a near-fit part.

This component delivers:

• Factory-correct fit in the mist spray lance — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• 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 spray lance shaft, operators risk:

• Mid-job failure during an application window
• Collateral damage to surrounding components
• Progressive damage that turns a cheap fix into an expensive one
• Coverage quality the customer can see in the field
• 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

Inspect it honestly. Replace it once. Fit it right. Keep it flying.

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

Take the load off the lance before you loosen anything at the root. Drain and flush the system, disconnect the fluid line and the atomizer cable, and support the atomizer end in your hand or on a padded rest, because a shaft that is only held by its root joint will drop the moment the clamp releases and it will land on the atomizer head. Never let a lance hang by its cable while you work, and never use the atomizer as a handle to pull the shaft out.

Mark the shaft before it moves. Put a witness mark across the joint at the root so you can see both the rotational position and the insertion depth, and photograph the hose route, the clip stations, and the cable path along the shaft first. Those two settings are what aim the atomizer and what set the length everything routed along the shaft needs. Getting them back by eye is how a lance goes on straight and sprays wrong.

Refit dry, square, and in stages. Slide the shaft home to the marked depth, set the rotation to the witness mark, then bring the clamp up evenly rather than pulling one side down first, since a slender shaft pulled crooked into a clamp will hold that crookedness after it is tight. Support the atomizer end while you tighten. Check afterwards that the shaft can neither be rotated nor drawn out by hand, and that the hose has its original slack rather than being stretched between stations.

While the lance is apart, look at everything the same event or the same season has been working on. Check the Mist Spray Lance Connector and the bore the shaft lands in, the Mist Sprinkler Support Rod and its ends, the atomizer head for a chipped or residue-loaded disc that has been feeding imbalance into the shaft, the fluid line where clips gripped it, and the Centrifugal Sprinkler Adapter Cable if that option is fitted. A shaft rarely fails alone, and the second teardown always lands on a spray day.

Do not straighten a bent lance shaft and put it back on. Whatever the shaft is made from, straightening works the damaged region a second time in the opposite direction, and what comes back is a part that measures straight while having lost strength and ductility exactly where the next load will concentrate. On a composite tube the damage may be delamination that never shows on the outside at all. A straightened shaft is a part that has stopped warning you before it fails.

The habits that shorten a shaft's life are all ground habits. Lifting or dragging the aircraft by a lance, strapping over the shaft on a trailer, leaning it against a wall while the tank is filled, and pressure-washing straight into the root joint all put loads or moisture where the design does not expect them. Rinse chemical residue off the lance at the end of the day, dry the clamped joint, and store the aircraft so nothing rests on or bears against the shafts.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 Spray Lance Shaft? It is the OEM spray lance shaft serving the mist spray lance 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 Spray Lance Shaft? The DJI material number is YC.JG.QX004533, 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 component 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 spray lance shaft needs replacing? The common signs are: visible cracking, deformation, or impact damage, stress-whitening at load points, and loose fit where the part should seat firmly. Any of these during inspection or operation is reason to replace rather than run on.

What causes this component 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.QX004533 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 mist spray lance, document connections and hardware positions, swap the spray lance shaft 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.

What other parts should I inspect at the same time? On the official diagram this part sits alongside Mist Sprinkler Support Rod, Mist Spray Lance Connector, Centrifugal Sprinkler Adapter Cable (Optional). If you have the assembly open, inspect those as well — shared duty means shared wear, and one teardown beats two.

Where can I buy this part in the USA? Ares Acres is a U.S.-based authorized DJI Agras reseller stocking the Spray Lance Shaft (YC.JG.QX004533) with free and fast U.S. shipping, plus same-day shipping and tracking on in-stock parts.

Is this the lance shaft or the support rod? They look similar in the diagram.

They are different parts with different jobs. The shaft is the primary member that carries the atomizer and takes the bending load at its root. The support rod braces against it and carries far less. On the Mist Spray Lance sheet they sit next to each other and photograph much alike, so go by material number: this listing is YC.JG.QX004533. Fitting a brace where a load-carrying shaft belongs is a failure waiting for the first hard pass.

One side of my swath is heavier than the other. Would a bent shaft do that?

It can, and it is worth ruling in or out before you tear into the pump or the nozzles. The shaft sets where the atomizer sits and how it is angled into the rotor wash, and the spray pattern was calibrated around that geometry. Compare the two atomizer heads against the same fixed point on each side of the airframe, look for a droop or a twist at the root, and check whether the shaft has rotated in its clamp since the last time it was off.

Can a bent shaft be straightened rather than replaced?

No. Straightening reloads the damaged region in the opposite direction and returns a part that measures straight while having lost strength precisely where the highest load lands. If the shaft is a composite tube, the real damage may be internal delamination that never appears on the surface, so a straight-looking part tells you nothing. The failure mode after straightening tends to be a break rather than a bend, which removes the warning you would otherwise get.

The atomizer wobbles at one throttle setting and is fine above and below it. Shaft or atomizer?

That pattern points at stiffness rather than balance. A wobble that appears in a narrow band and disappears either side of it is resonance, which usually means the root joint has loosened or the shaft has been damaged and the assembly no longer has the stiffness it was built with. An imbalance in the atomizer head itself, from a chipped disc or dried product build-up, more often produces vibration that grows steadily with speed instead of peaking and fading.

Do the left and right lances use the same shaft?

The breakdown reproduced in this listing states the material number and position but does not say whether the two sides are interchangeable, so do not assume either way. Check the number on the part you removed, note which side it came off before it leaves the aircraft, and match it. If both sides carry the same number, order two when the aircraft has taken a strike, because a knock hard enough to move one lance often loosened the other.

Do I need to re-aim or re-calibrate anything after fitting a new shaft?

There is no calibration figure published for this in the listing, so the practical answer is to reproduce the original geometry rather than to set a new one. That means matching the insertion depth and rotation you marked before removal, checking the new atomizer head sits at the same height and angle as the one on the other side, and running a ground function check with water to confirm the pattern looks the same from both lances before you take chemical to a field.
