Combine Harvester Seat Supplierfor Machine Builders and Distributors: Seat Checklist for Long Harvest Shifts

KL Seating is a seat manufacturer and factory direct supplier for combine harvester builders, and for distributors and importers who supply replacement seats to harvesting fleets and workshops. Combine harvesters appear in the agricultural machinery application list of our seat range, next to tractors, seeders and sprayers.

A harvest season puts the operator in the seat for one long shift after another, with the head turning between the header and the grain tank. Send the harvester make and model, photos of the old seat from the front, the side and underneath, and the electrical voltage of the machine. We reply with the matching model.

Seat Selection Checklist for Long Harvest Shifts

Work through these five points in order. Each one narrows the choice before the model name is discussed.

Turning Posture: Backrest, Fore-Aft and Swivel Options in the Agricultural Line

These are the adjustment figures published for the air bag models in our agricultural line.

For a harvester operator who turns often, the useful questions are how far the backrest reclines, how much fore-aft travel the cab leaves, and whether a turning mechanism fits the base.

Send the free space around the seat position and the reply names the model that works within it.

Cover and Cleaning: PVC and Fabric Options for Dusty Cabs

PVC is the main cover material across our seat range. Dust is wiped off a PVC surface as part of the daily routine in the cab. Some models also offer a fabric cover.

YJ03Black PVC or fabric.
KL03Cover material is confirmed with the factory on enquiry.

Choose the cover from how your fleet is cleaned. A fleet that wipes the cab down every day looks at PVC first. A buyer who wants a fabric surface asks for the models that list it. Tell us the cleaning routine and the color you need, and the reply states which cover is available on the model.

Air bag models

Air Bag Seat Options in the KL Seating Agricultural Line: YJ03 and KL03

Our agricultural line includes two air bag suspension models. The table gives the figures published for each. These are the options in the line, and the matching of a model to a machine is done against your machine data.

The parameter sheet lists YJ03 for tractors, seeders and agricultural machinery in general, and KL03 for tractors, construction machines and agricultural machinery.

Model pages: YJ03 air suspension tractor seat and KL03 tractor seat. For the whole air suspension range see air suspension seats.

24V

YJ03 and KL03 both run on 24 V. The YJ03 drawing marks the air pump motor as 24 V.

24 V Supply Check Before Ordering an Air Bag Seat

A machine without 24 V at the seat position has nothing to power the air pump, so this point is checked before the model is compared.

Harvester builders

Confirm the electrical system of the machine at the design stage and put the 24 V requirement into the operator-station interface list beside the mounting data.

Distributors and workshops

Check the machine in front of you. Does it have 24 V at the seat, and did the old seat carry an air pump?

Send the voltage of the machine with your first message, and we reply with the confirmation. Pump current and connector details are not on the published sheet, so we do not print them here. The factory answers those points in the enquiry reply.

For seats suspended without an air pump, see mechanical suspension seats.

Cab base

Cab Base Fit: Mounting Holes, Free Space and Seat Height

Before a harvester seat is ordered, three things are measured on the machine.

  • Base holes. The hole pattern of the seat base. The mounting hole data for YJ03 and KL03 is requested from the factory.
  • Free space. The room forward, back and above the cushion, so the fore-aft travel and the seat height can be checked against the cab.
  • Electrical supply. The voltage at the seat position.

At the factory, 3D scanning checks base hole positions and the frame outer dimensions, and the result goes back to the buyer against the model parameter sheet. The seat fitment compatibility guide lists what to measure on the machine before the first message.

Model Match by Machine: Send the Harvester and the Old Seat

The parameter sheet prints machine types against each model, and it holds no model-to-harvester list. We therefore do not name a model for a harvester on this page.

This route works for builders fitting new machines and for distributors replacing seats in the field. The tractor line is covered on the tractor seats page, which carries the same air bag models and the other tractor model side by side.

  1. The harvester make and model
  2. Photos of the old seat
  3. The mounting hole situation
  4. The voltage of the machine

We reply with the model that matches and with the figures of that model that apply to your machine.

Where a figure is not on the sheet, the reply says Ask the factory and the factory confirms it.

Own production

Cushion, Frame and Fit Checks in Our Own Production

Harvester seats go through the production route used for the agricultural line: foam molding of cushion and backrest, precision stamping of the frame, robotic welding, and assembly of the suspension, slide and chosen options. The MES records quality inspection and delivery as part of one record chain.

Cushion

The pressure distribution comfort test is run on the seat cushion and records how pressure spreads over the surface while a person sits on it. No test values are published here.

Frame

CAE structural analysis is used on the seat frame at the design stage.

Dimensions

3D scanning checks hole positions and frame dimensions.

The testing center covers more than 300 m² with more than 20 devices and more than 30 test items. We make no claim about service life on this page.

Supply

OEM and ODM Supply for Harvester Builders and Distributors

Harvester builders

Supplied as OEM and ODM customers with customized, modular seat systems. The seat is fixed from your cab drawing and hole pattern, and structural changes go through our R&D center.

OEM and ODM seat manufacturer
