Kramer KB: light post-war tractors for reconstruction – one- and two-cylinder engines with 6.6 to 18.3 kW (9 to 25 hp), 503 to 1,843 cm³ displacement
The KB series emerged in the 1950s, when West Germany's reconstruction demanded above all light, affordable tractors for smaller farms. Kramer consistently positioned this series below its stronger K models.

The register lists 16 live models, from the KB 10 to the KB 25, built between 1951 and 1959. Output ranges from 6.6 to 18.3 kW, or 9 to 25 hp, weight from 750 to 1,620 kg, displacement from 503 to 1,843 cm3, across one- and two-cylinder engines.
With kerb weights often under a tonne and simple single-cylinder technology, the KB series targeted small farms that could not yet afford a full-size K-class tractor.
The tight model spacing in five-horsepower steps (KB 10, KB 12, KB 14 and so on) let buyers choose the power class that exactly matched their farm's needs.
With output up to 18.3 kW, the KB series stayed entirely within the smallest three-point category 0 under ISO 730; the PTO ran single-speed at 540 rpm, as was typical for small tractors of the period. Since Kramer fully abandoned tractor building as early as 1973, original parts for the KB series are now scarce and mainly sourced through specialist vintage-machinery dealers. The simple technology at least makes it easier to reproduce individual wear parts. Anyone looking for a KB will find help through collector circles more readily than through the open parts trade.

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.
