Josef Krümpel K – small tractors of the K 22, K 25 and K 28 range: two-cylinder diesels of 2,198 to 2,660 cm³ displacement, 1,650 to 2,100 kg unladen weight, 1,450 to 1,500 rpm
The K range from the maker Josef Krümpel comprises three ascending power steps, the K 22, K 25 and K 28, whose numbers denote the respective power class; the K 22 with a rated output of about 16 kW matches the stated type figure of 22 (metric horsepower). All three models carry horizontal two-cylinder diesel engines and follow the classic formula of small post-war farm tractors in their build.

The register lists here 3 versions with rated outputs up to 16.1 kW at 1,450 to 1,500 rpm, from horizontal two-cylinder diesels of 2,198 to 2,660 cm³. Unladen weights range from 1,650 to 2,100 kg, lengths from 2,710 to 2,750 mm, widths from 1,560 to 1,570 mm and a height of 1,750 mm; all three models run on diesel.
Small-series makers such as Krümpel met the post-war demand from smaller farms for affordable, easy-to-maintain tractors at a time when the big brands offered mainly larger, costlier models; such ranges usually stayed confined to regional markets and were built in modest numbers.
On a used purchase of these simple two-cylinder diesels, the condition of the injection pump and nozzles counts, the clutch and gearbox, the tightness of engine and cooling system, and rust on the frame and sheet-metal parts; since this is a small maker, parts must be sourced chiefly from salvage, reproduction and vintage-tractor hobbyist 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.
