Eicher 600 series – the last narrow-track and plantation tractors from Forstern (1986–1993): K, V, P and A, air-cooled two- to four-cylinders
The 600 series is Eicher's tractor programme of the late 1980s and early 1990s – according to the Traktorenlexikon the 642 K ran from 1986 to 1993 – built in Forstern near Munich, where Eicher had made air-cooled diesel tractors since 1936. After Massey Ferguson's shareholding in the 1970s the firm had concentrated on specialty tractors for vineyards, orchards, hops and vegetables; the 600s are the last generation of that direction before production in Forstern ended in the 1990s and the brand lived on at Eicher Motors in India.

The letters distinguish track width and version, and the register makes the logic visible in the widths: the K models (635 K, 642 K, 645 K) are the narrowest at 905 to 960 mm, the V models (648 V, 656 V, 666 V) measure 983 to 1,025 mm, the P models (656 P, 666 P, 680 P) 1,284 to 1,360 mm; an appended A always means four-wheel drive (642 K versus 642 KA, 656 P versus 656 PA) and makes the machine wider and about 150 kg heavier, and the B in PB and PAB marks an even wider version at 1,341 mm. The models run from 1,963 to 3,927 cm³ with two to four air-cooled cylinders, 56 to 80 hp where output is recorded, unladen weights from 1,510 to 2,825 kg, lengths from 2,495 to 3,450 mm and heights from 1,920 to 2,325 mm.
The air-cooled Eicher engines with individual cylinders on a common crankcase are regarded as robust and easy to repair; a cylinder can be replaced individually, and a radiator cannot leak because there is none.
On used tractors, the condition of cylinders and cooling blower, the gearbox, the steering on narrow-track models and the front axle on four-wheel-drive tractors count; parts supply runs through specialists and an active club scene.

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.
