KL03Tractor Seat Supplier for Tractor Builders and Distributors180 mm Air Suspension Travel on a 24 V Supply



KL Seating supplies the KL03 tractor seat to tractor and agricultural machine builders that specify a seat for a new operator station, and to distributors and importers that supply replacement seats for machines already working in the field. KL03 has air suspension with 180 mm of travel. Seat depth adjusts in three positions of 17.5 mm each. The seat slides 70 mm forward and 120 mm rearward, and it needs 24 V from the machine.
The parameter sheet lists KL03 for tractors, seeders, agricultural machinery and construction machines. Among the three tractor models on the range, KL03 carries the longest published travel: YJ03 and YY08 are both at 80 mm.

Selection Check: 180 mm Travel, 24 V Supply and Seat Depth Steps
Three items decide whether KL03 goes onto a machine. The first reply to an enquiry is built around them, in this order.

24 V supply at the seat position
KL03 is an air suspension seat that runs on 24 V, and the supply belongs to the machine. It is settled first, because a model with nothing to run on cannot be matched on the other two items.

Suspension travel, 180 mm
The cab has to give the seat room to travel 180 mm. A builder takes the free height from the operator-station drawing. A distributor measures it on the machine, with the old seat in place.

Seat depth, three positions of 17.5 mm
The depth setting is the adjustment that KL03 adds to the slide. A builder states how many positions the operator group needs. A distributor asks what the fleet drivers are used to on the seats they have now.
Everything else on the sheet, such as cover and options, is confirmed after these three items match.
180 mm Air Suspension Travel: The Longest Published Value in the Tractor Line
180mmThe tractor range has three travel values on the sheet. YJ03 is at 80 mm, YY08 is at 80 mm, and KL03 is at 180 mm. KL03 is the longest of the three.


The figure is the vertical envelope of the seat. For a builder, it goes into the operator-station specification. For a distributor, it is compared with the travel of the seat being replaced. A machine whose present seat travels 80 mm points to YJ03 or YY08. A machine specified for a longer stroke points to KL03.
The travel check in three steps
- 1
Free height
Measure the clear distance above and below the seat position, from the cab floor to the roof or the rear window line. This is the (the clear vertical room the seat has to travel in) the 180 mm has to fit into.
- 2
Seat height reference
The KL03 overall size is requested from the factory, so send your height limit and the reply states how it reads against the 180 mm.
- 3
Reply
The reply confirms the match, or names the figure that falls outside what the cab allows.
KL03 is an air suspension model. The full suspension line is described on the suspension seats page, where the travel scale of every model is set side by side.
Seat Depth Adjustment: Three Positions of 17.5 mm on KL03
KL03 adds seat depth adjustment to the usual fore-aft slide. The depth moves in three positions, and each step is 17.5 mm. Pick a position and read what the sheet gives for it.
- Three positions, numbered 1 to 3
- Each step is 17.5 mm on the parameter sheet
The sheet gives the step size and the number of positions. A total seat depth range is not published; the reply states what the factory can confirm.
Email the positions you need



| Position | Step | Reading |
|---|---|---|
| Position 1 | 17.5 mm | One of three seat depth positions |
| Position 2 | 17.5 mm | One of three seat depth positions |
| Position 3 | 17.5 mm | One of three seat depth positions |
Positions the operator group needs
One fleet operator group may use one position. A mixed group may use all three. Name it in the first message.
Position the machine is delivered in
A builder states the default position for the operator station. A distributor can leave it to the reply.
Reach to the controls
Measure from the seat base to the pedals and levers. The slide sets that distance, and the seat depth is the second adjustment on top of it.
If your cab or operator specification states a depth range, send it with the enquiry and the factory answers against it.
Fore-Aft Slide: 70 mm Forward and 120 mm Rearward
The KL03 slide is written as two figures, and both are printed the way the sheet gives them. The rearward travel is the longer of the two, so the space behind the seat position matters more than the space in front of it.

| Direction | Figure | What to measure |
|---|---|---|
| Forward | 70 mm | Distance from the seat base to the pedals and levers |
| Rearward | 120 mm | Distance from the seat base to the rear wall of the cab or any fitted equipment |
A builder checks both against the operator-station drawing. A distributor compares them with the slide of the seat being replaced, and sends the old seat's forward and rearward figures if they are known. The fore-aft figures of the other tractor models are on the tractor seats page.
24 V Supply: The Interface Item Confirmed With the Factory Before the Model
24V
KL03 needs a 24 V supply at the seat position. The seat brings its air suspension, and the machine brings the electrical feed. Nothing on the seat side changes the voltage of the machine, so the question goes to the machine first.
KL03 has no drawing on file, so the electrical details of the seat come from the factory in the reply. No current figure or connector form is printed on this page, and no 24 V feed is described for a machine that has none.
What is asked
- 1
Machine builder
Does the machine electrical system provide 24 V at the seat position, and is the wiring to that position part of the cab design?
- 2
Distributor or refit shop
What is the voltage information of the machine? Does the seat you are replacing carry a 24 V connection, and where does it sit?
- 3
Reply
A confirmation against what you wrote, plus the list of electrical points the factory answers.
Put the voltage of your machine in the first message. The reply then starts at the model instead of the questions. YJ03 carries the same 24 V condition, and the two models are compared next.
KL03 Against YJ03: Selection Table for the Two Air Suspension Tractor Seats
YJ03 and KL03 are the two air suspension models in the tractor line, and both need 24 V. They differ in travel and in how much of the sheet is published.
| Item | KL03 | YJ03 |
|---|---|---|
| Suspension | Air suspension (air bag) | Air bag |
| Suspension travel | 180 mm | 80 mm |
| Supply | 24 V | 24 V, marked on the drawing |
| Operator weight setting | Confirmed in the reply | 50–130 kg |
| Fore-aft adjustment | 70 mm forward, 120 mm rearward | 175 mm |
| Seat depth | Three positions, 17.5 mm each | Not listed |
| Backrest angle | Requested from the factory | 35°–170° |
| Overall size | Requested from the factory | 525 × 610 × 780 mm |
| External drawing | None on file | Available |
| Machines on the sheet | Tractor, seeder, agricultural machinery, construction machines | Tractor, seeder, agricultural machinery |

YJ03 air suspension tractor seatA distributor who is unsure between the two sends the travel of the old seat. 80 mm points to YJ03. A longer stroke points to KL03.
Machines on the Sheet: Tractors, Seeders, Agricultural Machinery and Construction Machines
The Application line of the KL03 parameter sheet lists tractor, seeder, agricultural machinery and construction machines. KL03 is the only model in the tractor line whose sheet also lists construction machines.
Tractors and seeders
KL03 sits on the same tractor range as YJ03 and YY08, described on the tractor seats page.
Agricultural machinery
The sheet line names agricultural machinery next to tractors and seeders. Send the machine and a photo of the seat position for the match.
Construction machines
The entry on the sheet is a reason to ask about KL03 next to the construction models, listed on the construction machinery seats page.
Send the make and model of the machine and a photo of the seat position, and the reply gives the match. KL03 is not mapped to individual construction machine types beyond the sheet line.
Items Requested From the Factory: Weight Setting, Backrest Angle, Size and Base Holes
Five items on KL03 are not in the published material. Naming them in the first message puts them on the factory's list from the start.
| Item | What you send | What the factory returns |
|---|---|---|
| (ask the factory) | Lightest and heaviest operator for the machine | The weight range KL03 is set for, in the reply |
| Backrest angle | The recline range the operator station needs | The KL03 backrest range |
| Overall size | Cab envelope around the seat position | The KL03 size on the model sheet |
| Base hole pattern | Hole positions on your seat base or cab drawing | The KL03 hole positions, or the change that closes the gap |
| Cover and options | Cover and options wanted | The cover and option list for KL03 |

No weight band is given for KL03 on this page, and the weight bands of other models are not quoted for it. The reply states the KL03 figure after the factory confirms it. The same applies to the backrest range, the size and the hole pattern.
Mounting Data: Base Hole Pattern Request and 3D Scan Fit Check
KL03 has no overall dimensions, mounting hole data or drawing in the published material. They are requested from the factory with your enquiry. The reply states what the factory can send; no delivery date is promised on this page.
From you- The hole positions on your seat base, measured or taken from the cab drawing.
- The footprint of the old seat, if you are replacing one.
- The rails or frame the seat sits on, with a photo.

3D scanning in the testing center compares hole positions and frame dimensions. The result goes back to you as the figures on the model sheet. If the pattern on your machine differs, the factory states which modification closes the gap, and a change to the structure goes through the R&D center. For measuring a seat base against a model, the seat fitment guide walks through the measurements.
KL03 Production Route: Foam Molding, Precision Stamping, Robotic Welding and Assembly
- Foam molding
- Precision stamping
- Robotic welding
- Assembly
KL03 is built on the KL Seating lines. Three checks in the testing center apply to a seat of this kind:
- CAE structural analysis on the seat frame at the design stage.
- 3D scanning on frame dimensions and hole positions.
- Pressure distribution test on the seat cushion, recording how pressure spreads while a person sits on it.

Foam molding
The cushion and the backrest are formed by foam molding.

Precision stamping
The frame is precision stamped.

Robotic welding
The stamped parts are joined in the robotic welding station.

Assembly
Assembly puts together the air suspension, the slide and the options you chose.
How the air suspension travel of KL03 is tested is not in the published material, so it is not described here.
No test values are published on this page, and no claim is made about service life or vibration. The MES system covers quality and delivery records for the whole process, and the factory can describe the production route at a visit.
Cover and Options: Confirmed for KL03 in the Enquiry Reply
The cover and option list of KL03 is not in the published material. The reply to your enquiry gives both, written into the specification of the model you receive.

Photos show the sample seat; the option set is listed in the reply.
What to put in the first message
- Cover. PVC or fabric, and the color you want.
- Operator comfort items. Armrest, headrest, safety belt, or none.
- Machine items. Any switch or wiring point the machine design needs at the seat.
| Item | How it is confirmed |
|---|---|
| Cover and comfort items | Listed in the KL03 reply, written into the specification |
| Machine items | Factory answer against the switch or wiring point you name |
An option goes onto KL03 when the KL03 reply lists it. The option list of another model is not carried over to KL03. Where you need an option the reply does not list, say so, and the factory answers whether it can be specified.
