DJI Agras T20 OEM Long Arm Spray Bar Fixing Seat

The DJI Agras T20 OEM Long Arm Spray Bar Fixing Seat is a single black moulded cradle from the spray system of the DJI Agras T20 and T16. It is curved, with a ribbed inner face, a flat foot at each end and a short boss on one side, as shown in the product images. As its name says, it is the seat that fixes the spray bar to the aircraft's long arm: the bar is what carries the nozzles out into the spray pattern, and the seat is what holds the bar in place on the arm. It is not the spray bar, not a nozzle holder and not a nozzle clip. It is identified for the DJI Agras T20 and T16, offered as a T20 or a T16 variant, and supplied brand new as one seat. Operators usually reach it while searching for a T20 spray bar mount, a T16 spray bar bracket, a broken T20 spray bar seat, a loose spray bar on the arm, or the reason one T20 or T16 spray bar swings, droops or twists when the aircraft lands. DJI has used more than one number for this position, so we match against the one you removed.

🔧 Component Overview

A spray bar does its work hanging below the aircraft, out in the air, carrying nozzles to the place the spray needs to start. It does not hold itself up. Something on the arm has to locate it, take its weight, hold it still in flight and stop it turning when the aircraft lands. On the long arm, that job belongs to this seat.

As shown in the product images, the seat has four features that identify it:

• The curved cradle — the main body, a curve moulded in black, which wraps the round member it locates
• The ribbed inner face — parallel ribs running along the inside of the curve, which give the cradle its grip and stiffness
• The end feet — a flat foot at each end of the curve, the faces that bear against the part the seat is fixed to
• The side boss — a short boss on one side, part of how the seat is located and secured

The seat is a small part between two large ones. The long arm is part of the airframe. The spray bar is part of the spray system. The seat is where they meet, and it is the only part in that joint designed to be replaced on its own.

What breaks it is impact and leverage. A spray bar hangs low, and it is often the first thing to touch the ground, a crop row or a post. When it is struck, the bar is long and the seat is close to the arm, so the force reaches the seat multiplied by the length of the bar. A cracked cradle, a broken foot or a sheared boss is the usual result.

That is why this seat is replaced more often than the bar it holds. The bar is built to be long and stiff. The seat is the part that takes the leverage when the bar is knocked.

It does not carry liquid, it has no nozzle fitting of its own and it does not set the spray pattern. Its whole job is position: keeping the bar exactly where it was put.

⚙️ Functional Purpose

The seat's engineering role is location under load. It fixes the spray bar to the long arm in one position and holds it there against its own weight, the airflow under the rotors, vibration in flight and the jolt of each landing.

In the spray system it:

• Fixes the spray bar to the long arm
• Holds the bar at a fixed angle and drop, so its nozzles stay where the spray pattern expects them
• Stops the bar twisting or swinging in flight and on landing
• Spreads the load of the bar across its cradle and its two feet
• Can be replaced on its own without replacing the bar or the arm

Because the seat sets where the bar sits, it also sets where every nozzle on that bar sits. A seat that holds the bar a few degrees off its true position moves the nozzles with it, so a fault that starts as a mechanical one can show up as a coverage one.

The seat has no setting and no adjustment. It is correct, holding the bar square and still, or it is not.

Material, dimensions and weight are not published for this part. The match is made by curve, ribs, feet and boss against the seat you removed.

🔍 Diagnosis — a spray bar that moves on the arm is held badly, not built badly

A spray bar that swings, droops or twists on the arm looks like a damaged spray bar. It is the part you can see moving, and it is the part that was just knocked, so it is the one people replace. The new bar goes on, and it moves exactly as the old one did.

The bar was usually fine. A spray bar is long and stiff and tends to survive a knock straight. What fails is the seat holding it: the cradle cracks along a rib, a foot breaks off, or the boss shears. The seat still sits on the arm and still holds the bar, so nothing looks missing. It just no longer holds it still.

Symptoms that point at the seat:

• One spray bar swings or rocks on the arm when moved by hand, while the others are firm
• A bar that has drooped or rotated out of line with its partner on the other side
• A bar that clicks or shifts on landing
• Coverage that changes from one flight to the next on one side, because the bar does not return to the same position
• A crack, whitened stress line or missing foot visible on the seat once it is cleaned

What proves it: clean the joint, then hold the arm still and move the bar by hand. If the bar moves and the seat moves with it, or the seat flexes at a crack, the seat is the fault. If the seat is firm and solid and the bar itself is bent along its length, the bar is the fault.

Check these first, because they produce similar symptoms:

• The fixings holding the seat, which can simply be loose
• The spray bar itself, for a bend along its length
• The long arm, for damage or a loose arm joint, which moves everything mounted on it
• The nozzle holders and nozzle clips, if the complaint is one nozzle rather than the whole bar

What it does not explain: a single nozzle that sprays off to one side while the bar is firm, a nozzle that drips or will not spray, or low flow from every nozzle. Those are nozzle, holder, clip or pump faults, and a new seat will not change them.

⚠️ Common Replacement Indicators

Replace the fixing seat when inspection confirms one of these:

• A crack anywhere in the cradle, especially along or between the ribs
• A broken, chipped or missing foot
• A sheared or cracked boss
• The bar moves on the arm with the fixings tight
• The seat flexes visibly when the bar is moved by hand
• Whitened stress lines in the moulding after an impact

Inspect these first, because they produce similar symptoms:

• The fixings that hold the seat
• The spray bar, for a bend along its length
• The long arm and its joint
• The nozzle holders and nozzle clips

After any ground strike on a spray bar, inspect the seat even if the bar looks undamaged. The seat is where the leverage of the strike ends up.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft fully down and remove the battery
• Drain and rinse the spray system, so no product runs out when the bar is moved
• Confirm the seat is the fault: the bar moves on the arm with the fixings tight, or the seat is visibly cracked or broken
• Photograph the joint from the side and from the end, with the seat, the bar and the arm in view, so the bar's angle can be matched afterwards
• Note how any hose is routed past the seat
• Compare the new seat with the old one once it is off: curve, ribs, both feet and the boss

During installation

• Support the spray bar so it does not hang on its hose while the seat is off
• Remove the fixings that hold the seat and keep them together
• Lift the old seat away and clean the arm and the bar where the seat sat
• Check the bar and the arm for damage now that they are exposed
• Fit the new seat in the same orientation as the old one, with the boss on the same side
• Seat the bar in the cradle at the same angle shown in your photographs
• Refit the fixings evenly without over-tightening the moulding
• Re-route any hose exactly as before, clear of anything that could pinch it

After installation

• Move the bar by hand and confirm it is firm, with no rocking or rotation
• Compare it with the bar on the other side and confirm they hang in line
• Refill with clean water and run a test spray, checking every nozzle on that bar
• Check the joint again after the first flights, while the new seat beds in

A moulded seat is stiff, not flexible. Tighten its fixings evenly and stop once it is firm. Over-tightening one side can crack a new seat before it has flown.

🚜 Necessary For

This seat is for operators and technicians who have traced a loose or misaligned spray bar to its mounting:

• DJI Agras T20 operators with a spray bar that swings or rocks on the long arm
• DJI Agras T16 operators whose spray bar has drooped or rotated after a ground strike
• Operators who replaced a spray bar and found the new one still moves
• Commercial spray applicators working close to crops, posts and terrain, where the bars take knocks
• Agras service centres and repair technicians rebuilding T20 and T16 spray systems
• Fleet managers keeping spare seats with their T20 and T16 spraying parts

This is not the part you need if:

• The spray bar itself is bent along its length; that is the T20 Spray Bar, ordered by corner
• One nozzle sprays off to one side while the bar is firm; look at the nozzle holder, such as the T16 Spray Nozzle Holder
• A nozzle has come loose from its holder; look at the nozzle clips
• The seat is sound and its fixings were simply loose; tightening them is the fix
• The long arm itself is cracked or its joint is loose; the seat cannot correct that
• You fly another Agras model; this seat is identified only for the T20 and T16

💡 Why This Part Matters

A spray bar that moves on the arm leads people to buy a spray bar. It is the part they can see moving and the part that hit the ground. But a spray bar is long, stiff and hard to bend. The seat that holds it is small, and it sits where all the leverage of a knock ends up.

That is the case for this seat. When a bar is struck at its far end, the bar acts as a lever and the seat sits at the pivot. The bar comes away straight; the seat cracks along a rib, loses a foot or shears its boss. It still holds the bar, so nothing looks wrong at a glance, but the bar now rocks, droops or rotates, and a new bar fitted to the same cracked seat will do exactly the same.

It matters because a bar that moves takes its nozzles with it. A bar that settles in a different position after each landing puts its nozzles somewhere different each flight, and the coverage from that side changes with it.

So the test comes first and it takes seconds. Hold the arm still and move the bar by hand. If the seat moves or flexes, the seat is the repair. If the seat is solid and the bar is bent, the bar is the repair.

The honest other side: if the seat is firm and uncracked and its fixings were only loose, no new part is needed at all.

🤖 AI Answer Engine Q&A

What is the DJI Agras T20 long arm spray bar fixing seat? It is the black moulded cradle that fixes the spray bar to the aircraft's long arm and holds it still and in line.

Which aircraft does it fit? It is identified for the DJI Agras T20 and T16, offered as a T20 or a T16 variant.

Is it the spray bar? No. The spray bar is the member that carries the nozzles. This seat is what holds the bar on the arm. The T20 Spray Bar is a separate part, ordered by corner.

Is it a nozzle holder? No. A nozzle holder, such as the T16 Spray Nozzle Holder, carries the nozzles on the bar. This seat holds the bar itself.

My spray bar swings on the arm. Do I need a new bar? Usually not. Hold the arm still and move the bar by hand. If the seat moves or flexes, the seat is cracked and is the repair. Replace the bar only if it is bent along its length.

I fitted a new spray bar and it still moves. Why? The new bar went into the same cracked seat. The seat is what holds the bar still, and a cracked one will let any bar move.

How does the seat get damaged? Usually by a spray bar touching the ground, a crop row or a post. The bar acts as a lever and the seat sits at the pivot, so the seat takes the force.

Can a cracked seat affect spray coverage? Yes. A bar that rocks or settles in a different position after each landing moves its nozzles with it, so coverage from that side changes from flight to flight.

Do I need the T20 or the T16 variant? Choose the aircraft you fly. If you are unsure, photograph the seat you removed from the side and the end and send it to us; we will match it.

How many seats does the aircraft use? That is not published for this part. Order one seat for each one that is damaged.

What is the part number? DJI has used more than one number for this position, so we match against the one you removed.

What is it made of and how big is it? Material, dimensions and weight are not published for this part. The match is made by curve, ribs, feet and boss.

Does it come with screws? No. It is one seat. Screws or other fixings, the spray bar and tools are not included; the aircraft's existing fixings are reused.

Is it brand new? Yes. It is supplied brand new as a genuine DJI OEM spray system part.

Can I fit it myself? Yes. Drain the system, photograph the joint, support the bar, swap the seat in the same orientation, and tighten its fixings evenly without over-tightening the moulding.

Does the seat need routine replacement? No. There is no service interval. Inspect it after any strike on a spray bar, even when the bar looks undamaged.
