Hürlimann H-Reihe – four-cylinder petrol field tractors from Wil, Switzerland: types H-10 to H-20, 2,060 to 4,020 cm³ displacement, 19.1 to 33.1 kW, unladen weights of 1,440 to 1,660 kg
Hürlimann, the Swiss tractor works headquartered in Wil in the canton of St. Gallen, founded by Hans Hürlimann, lists the H range in the register with the types H-10, H-12, H-17 and H-20. The type numbers traditionally followed Hürlimann's approximate power class of the engine; the H range was fitted throughout with four-cylinder petrol engines, at a time when diesel engines were not yet universally standard in Swiss agricultural machinery.

The register lists 4 versions with 19.1 to 33.1 kW from four-cylinder engines throughout, of 2,060 to 4,020 cm³ displacement, unladen weights from 1,440 to 1,660 kg and rated speeds from 1,400 to 1,700 rpm; lengths range from 2,660 to 2,760 mm, widths from 1,490 to 1,585 mm, heights from 1,460 to 1,480 mm.
Hürlimann's H-range tractors supplied Swiss farms in hilly and mountainous terrain, where compact dimensions and a low centre of gravity gave an advantage over larger field tractors, competing with other Swiss and southern German makers of small tractors.
On a used Hürlimann H-range tractor, the condition of the petrol engine's carburettor and ignition system, rust on the frame and mudguards, the tightness of the gearbox and axles, and the function of the brakes and steering after decades of use all count; because production has ended, parts are mostly only available within enthusiast and collector circles.

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.
