Lindner BF series (1948 to 1960s) – the Bauernfreund from Kundl in Tyrol: BF 14 to BF 45, the number as hp class, N and A for standard and four-wheel-drive versions, two- and three-cylinder diesels of 1.0 to 2.5 litres
Lindner of Kundl in the Tyrolean Inn valley built its first tractor in 1948 and called it Bauernfreund – farmer's friend, BF – a name that became the programme: small, light tractors for the mountain farmers of Tyrol, Vorarlberg and South Tyrol, working on steep meadows and tight farmsteads where the tractors of the big makers are too heavy and too wide. The type logic: BF marks the range, the number the hp class – BF 14 about 14 hp, BF 22 22 hp, BF 30 30 hp, BF 45 about 45 hp – N the standard version with rear-wheel drive, A the four-wheel-drive version Lindner offered early because it is indispensable on slopes; GT on the BF 320 and a on the BF 45a are equipment and generation suffixes. The engines are bought-in two- and three-cylinder diesels of 1.0 to 2.5 litres at 2,400 to 2,800 rpm.

The register lists 8 versions with 14 to 32 hp from two- and three-cylinders of 1,000 to 2,502 cm³, unladen weights from 952 to 1,800 kg, lengths from 2,405 to 3,400 mm, widths from 1,460 to 1,760 mm and heights from 1,370 to 1,470 mm.
The BF range laid the foundation for Lindner's role as mountain-tractor specialist, which the family continues in Kundl today with the Geotrac, Lintrac and Unitrac ranges; the Bauernfreunds are collectors' pieces in Tyrol with their own scene.
On used tractors, originality, engine condition (parts depend on the engine supplier), clutch, gearbox and four-wheel-drive clutch on A models, brakes (decisive on slopes), hydraulics and sheet metal count; parts run through Lindner and vintage 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.
