Lindner 50 series – the Bergfreund range BF 250, BF 350 and BF 450 from Kundl: two- to four-cylinder diesels, 25 to 45 hp, 2,400 to 2,600 rpm
Lindner has built tractors in Kundl in Tyrol since 1948, with a focus on tractors for mountain farming. The 50 series with the BF 250, BF 350 and BF 450 types carries the BF abbreviation for Bergfreund, the name of Lindner's early ranges, and is available in the N, A and GT equipment levels.

The register lists here 3 versions with 25 to 45 hp from two- to four-cylinder diesel engines of 1,570 to 2,500 cm³ displacement at rated speeds of 2,400 to 2,600 rpm. Unladen weights lie between 1,220 and 1,620 kg, lengths between 3,100 and 3,370 mm, widths between 1,520 and 1,670 mm and heights between 1,340 and 1,350 mm.
As compact, light tractors for steep meadows and fields in the Alpine region, the Bergfreund models formed the basis of Lindner's reputation as a specialist in mountain farming, with customers mainly in Austria, Bavaria and South Tyrol.
On a used example, clutch and mechanical gearbox condition, hydraulic tightness, rust on chassis and mudguards after use on steep terrain, and brake function count; parts for the small diesels run through Lindner itself and independent farm-machinery workshops.
PTO shafts in this power class run at a standardised 540 revolutions per minute, sufficient for mowers, snow blowers and forage wagons in mountain operation. On the range's air-cooled early versions there is no radiator or coolant hose to check, but the cooling fins and fan need attention, as does the cylinder head for heat cracks after sustained hillside use. Lindner has remained an independent family company in Kundl, unlike many tractor makers of this generation that were absorbed into larger groups.

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.
