Lindner 50 series

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.
