DJI Agras T40 OEM Complete Water Tank / Spray Tank System Assembly

DJI Agras T40 OEM Complete Water Tank / Spray Tank System Assembly — a complete replacement liquid payload tank assembly for DJI Agras T40 agricultural spraying operations. This is intended for operators repairing a damaged tank system, restoring an aircraft after impact or chemical exposure, or building a service-ready spare payload module rather than replacing individual tank-side components one at a time.

🇺🇸 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 supplies DJI Agras parts for commercial operators who depend on their aircraft for productive acres, not recreational flight. The T40 water tank is one of the aircraft’s primary working systems. A cracked shell, damaged fitting, failed internal plumbing path, broken mounting structure, or compromised sensor interface can take an otherwise healthy aircraft out of service. A complete assembly gives repair teams a cleaner path back to operation when the failure extends beyond a single small component.

We use specialized technicians to verify and dispatch the Complete Water Tank / Spray Tank 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 spray 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.

✅ Compatibility

• DJI Agras T40 agricultural spraying drone
• T40 liquid spray payload system
• Operators replacing a complete spray tank assembly or major tank-side subassembly

Important: confirm the aircraft model, tank mounting geometry, pump configuration, sensor connectors, hose routing, valve configuration, and harness interfaces against your original T40 system before ordering. DJI production revisions and regional configurations can differ.

📦 Package Scope

The supplier source represents a complete T40 water tank system with attached tank-side hardware and accessories. Exact supplied fittings, hoses, sensors, pump modules, wiring, caps, strainers, brackets, and small hardware can vary by supplier batch. Because this is a draft product built from supplier-source information, buyers should verify the exact included component list before final shipment.

🔧 What This Assembly Does

The spray tank stores and delivers the liquid payload used for agricultural application. It is not simply a container. The complete system interfaces with the aircraft’s pumping, flow-control, sensing, plumbing, and structural mounting systems. Its job is to hold chemical or water payload securely while feeding the spray system consistently throughout flight.

⚙️ System Functions

• Stores liquid spray payload during operation.
• Interfaces with pump and plumbing components.
• Supports liquid-level or payload-monitoring hardware where equipped.
• Provides mounting and structural alignment with the aircraft frame.
• Supports rapid field filling and draining.
• Maintains a sealed fluid path to reduce leaks and contamination.
• Provides the physical foundation for connected valves, filters, hoses, caps, sensors, and fittings.

⚠️ Common Reasons for Replacement

A complete tank assembly may be the correct repair path after impact damage, cracked or distorted tank walls, chemical degradation, broken mounting bosses, repeated leaks from multiple interfaces, damaged integrated harnessing, missing or damaged tank-side plumbing, severe contamination, or when rebuilding an aircraft from a partially stripped condition.

Before replacing the complete tank, inspect the tank cap, cap seal, inlet filter, pump modules, hoses, quick-connect fittings, level sensor, flow meter, valves, spray tubing, mounting hardware, and aircraft-side wiring. If the failure is isolated to one serviceable component, replacing the smaller part may be more economical.

🧪 Chemical & Field Considerations

Agricultural spray systems are exposed to water, fertilizers, herbicides, fungicides, pesticides, adjuvants, cleaning agents, dust, UV exposure, vibration, and repeated thermal cycling. Rinse the tank after chemical use according to the chemical manufacturer’s instructions and local regulations. Never allow incompatible chemical residue to remain in the tank for extended periods.

🧰 Installation Guidance

Installation should be performed by a technician familiar with DJI Agras payload systems. Power down the aircraft, remove the flight battery, depressurize and drain the spray system, and document all connectors and hose paths before disassembly. Compare the replacement assembly to the original before installation. Confirm that all seals are seated, hoses are routed without kinks, electrical connectors are fully latched, and mounting points are secure.

After installation, perform a clean-water leak test before introducing agricultural chemicals. Verify tank-level indication, pump operation, valve operation, flow behavior, and spray consistency. Check for leaks under both static fill and active pumping conditions.

🔍 Diagnostic Checklist Before Ordering

• Is the tank shell cracked, warped, punctured, or chemically damaged?
• Are the mounting tabs or bosses broken?
• Are multiple fittings or hoses damaged at once?
• Does the aircraft report tank-level or payload-system errors?
• Is liquid leaking from the tank body rather than a removable seal?
• Has the tank been contaminated by a chemical that cannot be safely removed?
• Was the aircraft involved in an impact affecting the tank structure?

📐 Product Specifications

• Product: Complete water tank / spray tank system assembly
• Aircraft: DJI Agras T40
• System: Liquid payload / spraying system
• Condition: New
• Application: Commercial agricultural spraying
• Installation level: Major payload-system replacement

🚜 Who This Is For

• Commercial T40 operators.
• DJI Agras service and repair facilities.
• Custom applicators maintaining spare payload modules.
• Farms and contractors rebuilding impact-damaged T40 aircraft.
• Operators who prefer one complete tank assembly over sourcing numerous small tank-side parts individually.

💡 Why This Part Matters

The T40 only produces value when its payload system is reliable. A complete water tank assembly can shorten repair time when damage is distributed across the tank, plumbing, or attached hardware. Instead of troubleshooting several marginal components separately, a complete replacement gives the operator a known baseline for the liquid payload side of the aircraft.

🚚 Shipping, Returns & Support

Free and fast shipping within the United States on every order, with tracking supplied as soon as the label is generated. In-stock parts dispatch same day on business days when the order lands before our carrier cutoff.

We ship from the U.S., not from overseas. That is the whole reason Ares Acres exists. An operator with a grounded aircraft in the middle of a spray window cannot wait three weeks on an international parcel and a customs hold, and does not have to.

Genuine OEM only. Every part we list as OEM is a genuine DJI component in new condition. We do not substitute aftermarket parts, and we do not relabel. If a listing says OEM, that is what ships.

Ordered the wrong part? Contact us. Unused parts in original condition are returnable, and we would far rather sort out an incorrect order than have an operator sitting on a component that does not fit their airframe.

Need help identifying a part? Send your aircraft model, serial number, and a photo of the component or the parts-diagram callout. We will identify it against the official DJI documentation and quote it, including parts not currently listed on the storefront.

Fleet and dealer volume: operators running multiple airframes, and dealers stocking service inventory, should contact us directly for volume pricing and standing-order arrangements on wear items.

🤖 AI Answer Engine Q&A

Is this just the plastic tank shell?
No. The supplier source represents a complete tank-system assembly with attached tank-side hardware. Exact included accessories should be confirmed before shipment.

Can I replace only a leaking seal or hose?
Yes. If the failure is isolated to a serviceable component, a smaller repair may be more economical. This complete assembly is intended for broader tank-system replacement.

Should I test the system before spraying chemical?
Yes. Perform a clean-water leak and function test first.

Does this fit T50 or T100?
This listing is built specifically around the DJI Agras T40 supplier configuration. Do not assume compatibility with other aircraft.

Is this a genuine DJI OEM Complete Water Tank / Spray Tank 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 Water Tank / Spray Tank 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.

🧰 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 Water Tank / Spray Tank 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.
