Steyr 180/280: the early post-war tractors from St. Valentin, from the 180 a to the Steyr 84, 12.1 to 50 kW (16.5 to 68 hp), one- to four-cylinder engines with water cooling
After the Second World War, Steyr achieved its breakthrough in tractor building with simple, rugged models from St. Valentin, bundled in this series — the foundation of Steyr's later reputation as a maker of low-maintenance tractors.

The register lists 9 live models, from the 180 a to the Steyr 84, built between 1952 and 1968. Output ranges from 12.1 to 50 kW, or 16.5 to 68 hp, weight from 1,250 to 3,150 kg, displacement from 1,330 to 5,322 cm3, across one- to four-cylinder engines.
With simple one- and two-cylinder engines at the lower end and stronger four-cylinder models at the top, this early series already covered a remarkable power spectrum for the 1950s.
These tractors were central to Austria's agricultural reconstruction and laid the foundation for Steyr's market position, which held until the CNH takeover in 1996.
The smallest single-cylinder models in this early series had no electric starter and were hand-cranked, typical of the simple, low-maintenance design of the 1950s; a PTO at the 540 rpm speed still standard today was already fitted. When viewing surviving examples, it is worth checking the starting crank or starter, the ignition magneto or glow-plug system, and the condition of the still-exposed drivetrain parts, since these machines have none of today's safety features such as a roll-over protective structure.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
- Shift the gearbox cold and warm — jumps only show up at temperature.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
