Wolfenbütteler Traktoren WoTrak 22 hp – German post-war tractor built 1949 to 1950: two-cylinder diesel of 2,198 cc, 22 hp at 1,500 rpm, 1,700 kg weight, circulating water cooling
Wolfenbütteler Traktoren GmbH already carries the town of Wolfenbüttel in Lower Saxony in its name; the WoTrak 22 hp was built in the first post-war year of 1949 and continued until 1950, a time when many smaller German works produced their own tractors to help rebuild agriculture.

The two-cylinder diesel engine of 2,198 cc is cooled by water circulation and produces 22 hp, or 16.2 kW, at 1,500 rpm. At 1,700 kg, 2,300 mm long, with a 1,630 mm wheelbase and 1,520 mm width, the WoTrak reaches a design top speed of 18.5 km/h.
Tractors of this power class from the immediate post-war years were intended as versatile workhorses for medium-sized farms, with simple circulating water cooling rather than more elaborate thermosiphon or evaporative technology. The two-cylinder layout was a compromise between smooth running and simple, robust engineering, as offered by many small makers of those years.
When buying such a rare post-war tractor, the condition of the cylinder head and cooling circuit is decisive, as corrosion in old circulating water systems is common. Because such small-series makers built only limited numbers, original spare parts are hard to find, so the condition and completeness of the machine weigh more heavily on its value than with any mass-produced model of the same era.

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.
