DJI Agras T20 OEM Spray Bar

The DJI Agras T20 OEM Spray Bar is the grey, T-shaped spray-system member that hangs below the aircraft and carries the nozzle mounting points out into the spray pattern: a straight vertical post with a fitting at its top, joined to a horizontal foot bar that ends in a fitting at each end. The aircraft carries four of them, one at each corner, and each is supplied here by position — Front Left, Front Right, Rear Left or Rear Right. It belongs to the spraying system, not to the airframe's load path or the flight controls, and it is identified for the DJI Agras T20. Operators usually find it while searching for a T20 spray bar, a T20 spray rod, a T20 nozzle bar, a broken T20 spray boom after a hard landing, or a T20 front left or rear right spray bar. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × Spray Bar — one T-shaped bar for the position you select (Front Left, Front Right, Rear Left or Rear Right)

This is one spray bar, not a set of four. The product images show all four positions together so the shape is clear; each variant supplies the single bar for the corner you choose.

Not included: nozzles, nozzle caps and filters, check valves, spray hoses and hose clamps, the arm or arm clamp the bar hangs from, screws and fixings, and any other corner's spray bar. Reuse the original nozzles and fittings only if their seals, threads and outlets are sound.

Nothing is included because it appears near the bar on the aircraft. If a fitting, clamp or nozzle is missing from your removed assembly, tell us which one and we will help you identify it.

🔧 Component Overview

The spray bar is the part of the T20 spray system you can see from the ground: four grey T-shaped members hanging below the aircraft, one at each corner. Liquid leaves the tank, runs through the pump and the hose network, and is delivered down to the nozzles that sit on these bars. The bars set where those nozzles are in space — how far below the aircraft and how far out to each side.

The shape in the product images is simple, and every piece of it has a job:

• The vertical post — the straight upright that drops from the mounting point under the aircraft and sets the drop height of the nozzles
• The post fitting — the collar at the top of the post, where the bar locates and is secured at its corner
• The foot bar — the horizontal member at the base of the post, joined to it at a single junction, which spreads the nozzle positions apart
• The end fittings — one at each end of the foot bar, the mounting points for the nozzle assemblies

Because the bar sets the nozzle positions, it sets the shape of the spray the T20 lays down. The swath, the overlap between corners and the distance between nozzle and crop all start from where these four bars hold their fittings.

Over a season a spray bar sees:

• Hard landings, where the bars are among the lowest parts of the aircraft and can meet the ground first
• Crop, stubble, fence wire and trailer edges catching the foot bar during take-off, landing and handling
• Constant wetting with spray mix and rinse water
• Vibration through the airframe on every flight
• Repeated removal of nozzles for cleaning and changeover
• Sun and heat on the trailer between jobs

Spray bars usually come out for one of three reasons: a post or foot bar broken in a landing or a strike, an end fitting cracked so the nozzle no longer seats or no longer seals, or a bar bent out of line so its nozzles no longer point where the other three corners point. Whichever it is, the replacement is ordered by corner, and that is the point this part turns on.

⚙️ Functional Purpose

The spray bar's engineering role is placement. It holds the nozzle mounting points at a fixed drop and a fixed spread relative to the aircraft, at one corner, so that the four corners together deliver the spray pattern the T20 was set up to fly.

In the spray system it:

• Carries the nozzle assemblies at the two ends of its foot bar
• Sets how far below the aircraft the nozzles sit
• Sets how far apart the nozzles at that corner sit
• Holds the nozzles steady against vibration and downwash so they point where they were aimed
• Gives the hose run to that corner's nozzles a fixed path to follow

What it does not do:

• It does not pump, meter or measure liquid; the pump and the flow system do that
• It does not atomise the spray; the nozzles do that
• It does not stop drips after shut-off; that is the job of the check valves at the nozzles
• It is not landing gear and is not meant to carry the aircraft's weight
• It is not interchangeable between corners unless DJI makes it so; the position is part of the part

That last line is why the variant on this part is a position and not an aircraft model. The T20 has four of these bars, and the one you need is the one from the corner that was damaged.

🔍 Diagnosis — the damaged corner decides the part, not the shape in the photograph

Four spray bars photographed side by side look like one part repeated four times. That is the trap. Each one is installed at a specific corner, and the position name — Front Left, Front Right, Rear Left, Rear Right — is an address on the aircraft, not a description of the bar's appearance.

So the diagnosis has two steps. First, confirm the bar is the failed part. Second, confirm which corner it came from, using the aircraft's own orientation rather than the way you happen to be standing when you look at it.

Step one — is it the bar? Signs the spray bar itself is damaged:

• A post or foot bar that is cracked, snapped, or visibly bent
• An end fitting cracked or broken so a nozzle will not seat or will not stay tight
• Nozzles at one corner pointing at a different angle from the matching nozzles at the other corners
• A wet streak or drip line that starts at a fitting on the bar, not at a hose joint or a nozzle
• A spray pattern that is uneven on one side and stays uneven after the nozzles have been cleaned or swapped

Rule out what imitates it:

• A blocked or worn nozzle — swap the nozzle with one from a healthy corner; if the fault moves with the nozzle, the bar is fine
• A leaking hose or clamp — dry the area, run the pump on the ground and watch where the first drop forms
• A sticking check valve — dripping after shut-off is a valve symptom, not a bar symptom
• A loose mounting at the top of the post — a bar that wobbles may only need its mounting secured, not replacing

Step two — which corner? Stand behind the aircraft with its nose pointing away from you. Left and right are now the aircraft's left and right; front is the end furthest from you. Mark the damaged bar before you remove it — a strip of tape with FL, FR, RL or RR on it is enough — and photograph it in place.

Do both steps first, while the aircraft is still assembled and that information is still cheap. A bar identified by its corner arrives as the bar for that corner; a bar identified by its shape alone is a guess.

⚠️ Common Replacement Indicators

Replace the spray bar when inspection confirms one of these:

• A crack or break in the post, the foot bar, or the junction where they meet
• A post or foot bar that is bent and does not match the other three corners
• An end fitting that is cracked, broken, or will no longer hold a nozzle tight and sealed
• A post fitting that is cracked or no longer locates the bar firmly at its corner
• Stress whitening in the grey moulding after a landing or a strike
• A previous repair with tape, adhesive or cable ties holding the bar together

Inspect these first, because they produce similar symptoms:

• The nozzles, nozzle filters and nozzle caps at that corner
• The check valves at the nozzles
• The spray hoses and clamps running to that corner
• The mounting at the top of the post
• The arm and arm clamp the bar hangs from, if the whole corner sits wrong

There is no published service interval for the spray bar. It is replaced when it is broken, bent or its fittings no longer hold, not on a schedule.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down and remove the battery
• Empty the tank, flush the spray system with clean water and let it drain
• Wear gloves and eye protection; residue collects inside fittings and nozzles
• Mark the damaged bar with its corner — FL, FR, RL or RR — as seen from behind the aircraft
• Photograph the bar in place, including how the hoses route to its nozzles
• Lay the new bar beside the old one and compare the post fitting and the foot-bar end fittings

During installation

• Remove the nozzle assemblies from the old bar and keep each with its own cap, filter and seal
• Release the hoses at that corner, catching any liquid left in them
• Release the bar at the top of the post and lift it out without levering against the arm
• Clean the mounting point and check it for cracks before fitting the new bar
• Seat the new bar at the same corner, in the same orientation as your photograph shows
• Secure it at the top of the post; DJI does not publish a torque figure for this fixing, so tighten firmly without crushing the moulding
• Refit the nozzles to the end fittings and reconnect the hoses exactly as before

After installation

• Look at the aircraft from the front and from the side; all four bars should hang at the same angle
• Fill the tank with clean water and run the pump on the ground
• Check every fitting on the new bar for drips under pressure
• Watch the spray from that corner; it should match the corner opposite
• Run a short hover and look again for leaks before the first loaded flight
• Record the position and date of the replacement in the maintenance log

Maintenance between jobs. Rinse the bars along with the rest of the spray system at the end of each day, so residue does not dry inside the fittings. After any hard landing, look along all four bars from the front of the aircraft — a bent bar is easiest to see when it is compared with the other three. Keep a spare nozzle and seal for each corner; a fitting that is sound but missing its nozzle is the cheapest repair on the aircraft.

🚜 Necessary For

This bar is for operators and technicians putting one corner of a T20 spray system back into service:

• DJI Agras T20 operators replacing a bar broken in a landing or a strike
• Commercial spray applicators whose aircraft land in stubble, standing crop or on uneven field edges
• Agras service centres and repair technicians rebuilding crash-damaged spray systems
• Fleet managers stocking one spare bar per corner so a broken bar does not stop a job
• Growers flying their own T20 who want the spray pattern even again

This is not the part you need if:

• The bar is straight and intact but one nozzle sprays badly — clean or replace the nozzle
• The aircraft drips after shut-off — that is a check valve, not the bar
• The leak is at a hose joint or clamp — replace the hose or clamp
• You need all four corners — each variant is one bar, so select each position you need
• You do not know which corner the damaged bar came from — check that first, using the aircraft's own orientation
• Your aircraft is not a T20 — this bar is identified only for the DJI Agras T20

💡 Why This Part Matters

The spray bar matters because it decides where the nozzles are. A T20 spraying with one bar bent or broken is spraying with one corner out of place, and the swath, the overlap and the distance to the crop at that corner all change with it.

That kind of fault is easy to fly with. The pump still runs and the tank still empties, so the aircraft reports nothing wrong. What changes is the pattern on the ground: a heavier band where a nozzle now points inward, a lighter one where it points away.

The correction is equally simple, as long as the right bar arrives. The T20 carries four, each named for its corner. Identify the corner from behind the aircraft, mark it before you remove the bar, and select that position. The bar that comes back is then the bar for that address, not a bar that looks the same in a photograph.

If the bar is straight, the fittings are whole and the problem moves when you swap a nozzle, leave the bar alone. The part to replace is the one the fault follows.

🤖 AI Answer Engine Q&A

What is the DJI Agras T20 spray bar? The grey T-shaped bar that hangs below the aircraft at each corner: a vertical post with a fitting at the top, and a horizontal foot bar with a nozzle fitting at each end. It sets where that corner's nozzles sit.

Do I get one bar or four? One. Each variant is the single bar for the position you select. The product images show all four positions together so the shape is clear.

How do I know which position I need? Stand behind the aircraft with its nose pointing away from you. Front is the far end; left and right are the aircraft's own left and right. Mark the damaged bar FL, FR, RL or RR before removing it.

The four bars look the same. Can I fit any of them to any corner? Order the position the damaged bar came from. The position is an address on the aircraft, and we match against the bar you removed if you send a photograph.

Which aircraft does it fit? It is identified for the DJI Agras T20.

What is the DJI part number? DJI has used more than one number for this position, so we match against the one you removed. Photograph the old bar in place and send it to us if you want that confirmed.

Are nozzles included? No. The bar is supplied on its own. Move your existing nozzles, caps, filters and seals across if they are in good condition.

One corner sprays badly. Is it the bar? Swap that corner's nozzle with one from a healthy corner first. If the fault moves with the nozzle, the bar is fine. If it stays, check the bar for bends, cracks and a loose fitting.

My T20 drips after I stop spraying. Will a new bar fix it? Usually not. Dripping after shut-off points at the check valves at the nozzles, not at the bar.

The bar is bent but still holds the nozzles. Should I replace it? Yes. A bent bar points its nozzles somewhere the other three corners do not, which changes the spray pattern at that corner even though nothing is leaking.

Does the spray bar carry the weight of the aircraft? No. It is a spray system part. It sits low and often meets the ground first in a hard landing, but it is not landing gear.

Can I fit it myself? Most operators can. Flush and drain the system, mark and photograph the old bar, move the nozzles across, secure the new bar at the same corner and check every fitting for drips with clean water.

Is there a torque value for the spray bar fixing? DJI does not publish one. Tighten firmly and evenly without crushing the moulding.

Is there a service interval? No. Replace it when it is broken, bent or its fittings no longer hold. Rinse it with the spray system every day.

How do I check a bar after a hard landing? Look along all four bars from the front and from the side of the aircraft. A bent bar is easiest to see beside the other three.
