Widmann 8-10 (FAWI) – single-cylinder diesel tractor built until 1971: 763 cc displacement, 8 hp, evaporative cooling, 585 kg unladen weight, top speed of 20 km/h, wheelbase from 1,300 mm
The Widmann 8-10 of the FAWI line was built until 1971 and belongs to the class of small single-cylinder diesel tractors common on smaller farms in the post-war years. Nothing certain can be added about the company itself from the recorded values, so the description below rests on the machine class rather than on company history.

The single-cylinder diesel engine has a displacement of 763 cc, is tempered by evaporative cooling and produces 8 hp at 1,500 to 1,750 rpm. The tractor weighs 585 kg, is 2,000 mm long, 1,290 mm high and 1,270 mm wide, with a wheelbase starting at 1,300 mm. Its design top speed is 20 km/h.
Single-cylinder diesel engines with evaporative cooling, meaning without a water pump or radiator, were common in the early years of the small motorised tractor because they were simple and robust in daily use. A tractor of this power class was built for small plots, specialty crops and light draught work rather than heavy tillage or long field runs.
When buying a used single-cylinder tractor of this kind, the condition of the piston and cylinder matters most, as these engines in original condition often carry high running hours. The coolant level and tightness of the evaporative cooling system, the state of the pulleys and the bearing play on the front axle should be checked before purchase, as should the availability of simple wear parts such as gaskets and injectors.

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.
