The Steyr 9078 from the 9000 series is covered here by more than 250 matching parts, ranging from trailer couplings and lighting to classic tractor parts.
This page lists more than 250 parts that fit the Steyr 9078, supplied by GRANIT, Scharmüller, HELLA, Walterscheid and GRAMMER. The selection leans towards the jobs a farmer or mechanic does in the yard: hitching gear, cab switches, seats and lighting, with a handful of drivetrain and hydraulic items.
Drawbars, top drawbars, automatic hitches, Piton Fix and adapter plates are all here, from makers such as Scharmüller and Walterscheid. A height adjustable adapter plate makes it easier to set the hitch to the drawbar height of a trailer.
A tip from the workshop: check the coupling pin and the jaw guide of an automatic hitch for wear at every service. Once the pin is worn, the trailer eye knocks every time you pull away or brake, and the wear speeds up. A little grease on the sliding faces adds a lot of life.
Rocker switches, such as the powershift high and low switch in the dashboard, and push button switches for lifting and lowering the linkage keep the controls working. There are door locks, gas struts for the roof hatch and tractor seats, including an air suspended seat from GRAMMER.
Before you unplug a rocker switch, take a photo of the back. These switches often carry several contacts side by side, and a wire on the wrong pin causes faults that are hard to trace. Disconnect the negative battery lead before working in the dashboard.
Indicator and position lights and work lamps cover the lighting. For charging there is an alternator, and in the drivetrain and hydraulics you will find thrust bearings and seal kits, for example for an external lift cylinder.
The type plate confirms that your tractor is a 9078 from the Steyr 9000 series. Models in that series differ in detail, so do not go by looks alone. The reference number on the old part is the safest guide, usually etched on the outer ring of a thrust bearing or marked on the cylinder for a seal kit. Compare it with the details given with the product before you order.
Other tractors from the brand each have their own page, which you can reach through Steyr parts.
Gas struts for the roof hatch are best replaced as a pair, so the hatch opens straight and the hinges are not loaded on one side. When a new seat goes in, check the mounting points on the console first.
