Stihl – other models: the small single-cylinder collective page with the 140 and 144 types, 8.8 to 10.2 kW (around 14 hp), 633 to 763 cc diesel, under 800 kg
This collective page brings together two small single-cylinder diesel tractors designated 140 and 144, which sit outside the named ranges in the register. With under 800 cc displacement and kerb weights under 800 kg, both count among the smallest motorised tractors in the register, of the kind used on small agricultural plots, in orchards and vineyards, or as yard tractors for manoeuvring. Their compact dimensions made them easy to turn in tight rows and confined yards where larger machines could not work.

The register lists 2 variants at 8.8 to 10.2 kW (around 14 hp) from a single-cylinder diesel of 633 to 763 cc, kerb weights of 700 to 795 kg, lengths of 2,600 to 2,660 mm, widths of 1,500 to 1,570 mm, heights of 1,560 to 1,600 mm and a rated 1,850 to 2,000 rpm.
In this power class, such small tractors competed with similarly sized single-cylinder models from other makers offered in the 1950s and 1960s specifically for small holdings, specialist crops and steep terrain, where large standard tractors were too unwieldy.
On these small single-cylinder machines, compression and the condition of the injection pump matter, along with the clutch and gearbox, rust on wings and sheet metal, and – for use on slopes – brakes and steering; parts for such low production numbers are usually only available through specialist vintage dealers and custom remanufacture.

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.
