Kramer Pionier – the company's first post-war tractors from Überlingen on Lake Constance: Pionier, Pionier S and Pionier-S Schmalspur with single-cylinder diesels, 8.1 to 10.2 kW, 567 to 851 cm³ displacement
With the Pionier range, Kramer of Überlingen on Lake Constance entered the building of small farm tractors in the post-war years; the name Pionier stood programmatically for the company's fresh start after the Second World War. Alongside the standard Pionier there was the reinforced Pionier S and the narrow-track Pionier-S Schmalspur with a reduced wheel width for work between tight rows of trees and vines.

The register lists here 3 versions with 8.1 to 10.2 kW output at 2,300 to 2,800 rpm, from single-cylinder diesels of 567 to 851 cm³. Unladen weights range from 700 to 1,090 kg, with a uniform length of 2,600 mm, widths from 1,120 to 1,500 mm and a uniform height of 1,480 mm; all three models run on diesel.
The Pionier range targeted smaller farms and specialist crops that called for manoeuvrable, narrow tractors; it stood at the start of Kramer's tractor production, from which the KA range and further lines later descended before the company turned to building loaders.
On a used purchase of these early single-cylinder diesels, the condition of piston and cylinder liner counts, the injector and feed pump, the clutch and the simple gearbox, and rust on sheet-metal parts and steering knuckles; on the narrow-track version in particular it is worth checking the narrower axles and rims for wear. Parts now run mainly through vintage-tractor specialists.

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.
