Is your tractor a Steyr 9100 M from the M 9000 series? Then more than 200 matching parts are listed here, including lighting, trailer couplings and electrics.
A Steyr 9100 M is the kind of tractor you spend whole days in. You notice straight away when the roof hatch will not stay up, a dashboard switch plays up or the seat has lost its spring. For this model there are more than 200 new replacement parts on this page, from GRANIT, Scharmüller, HELLA, GRAMMER and PROBOSS.
For the 9100 M there are gas struts, including ones for the roof hatch. A strut that loses pressure lets the hatch or window creep shut. Fit a new gas strut with the piston rod pointing down, so the seal inside the cylinder stays lubricated and the strut lasts longer. Where struts work in pairs, always replace both together so the hatch is not loaded on one side.
At the rear there are drawbars for the rail system, automatic hitches and height adjustable adapter plates. For the driveline you will find thrust bearings in a closed design. Water pump gaskets, O-rings for the feed pump and sealing rings are part of the selection too, as are door locks and air suspended tractor seats for the cab.
With an automatic hitch, grease the coupling pin and the locking mechanism regularly. Sand and dirt make the mechanism stiff, and a hitch that does not lock fully is dangerous on the road.
An air suspended seat that slowly sinks often has a leak in the bellows or in the air line to the compressor. Before writing the seat off, switch the engine off and listen closely for a hiss from underneath it. If the seat really is worn out, a new tractor seat for this model makes a noticeable difference to your back. A door lock that no longer catches lets in draughts and dust, and is usually swapped with a few bolts.
Start with the data plate on the tractor. If the old part carries a reference number, compare it with the details on the product. For switches, the symbol on the button also helps you pick the right one.
Within the Steyr M 9000 range, the 9100 M has a smaller sibling with a page of its own. If that tractor is in your shed too, its parts are on the page for the Steyr 9080 M. Anything else carrying the Steyr badge is listed by model under Steyr parts.
