Brakes and transmission lead the way for the Steyr 4085 Kompakt, alongside trailer couplings and electrics. This page offers more than 170 matching parts.
The 4085 Kompakt earns its keep around the yard, in the shed and on lighter field jobs. Hard use means clutch parts, lights and the seat eventually need replacing. This page covers more than 170 parts for the model, from GRANIT, LUK, GRAMMER, Eaton and Scharmüller.
When you fit a new double clutch, always replace the thrust bearing at the same time, and check that all the release fingers sit at the same height once the unit is bolted up. Uneven fingers give a clutch that judders or will not release cleanly. If the PTO still refuses to engage afterwards, test the push button switch before you split the tractor again.
Check the serial plate to confirm it reads Steyr 4085 Kompakt. For clutch plates, count the splines and measure the hub, and for a mirror look at the diameter of the mounting arm. A clutch assembly or alternator that has been removed almost always carries a reference number you can compare with the new part.
If the roof hatch will not stay up, the gas struts are worn out. Replace them as a pair even when only one feels weak, and fit each strut with the rod facing down so its seal stays in oil. Support the hatch while you unclip the old struts.
Broken fender springs are a quick job too. Left alone, the fender shakes over every bump and eventually cracks at its mounting points.
Two more tractors from the Kompakt range have their own pages with the parts that fit them:

A Kompakt is often the tractor that gets used by everyone on the farm, so the seat and the clutch tend to wear faster than the hours suggest. Keeping a spare clutch plate and a set of gas struts on the shelf can save a lost afternoon at a busy time of year.
