Hermann Lanz – other models: the collective page of the Aulendorf maker outside the named ranges, one- to three-cylinder diesels of 1,558 to 2,232 cc, 8 to 16 kW
This page gathers the tractors of Hermann Lanz of Aulendorf in Upper Swabia that the register could not assign to a dedicated range. The maker Hermann Lanz should not be confused with the Mannheim firm Heinrich Lanz, whose Bulldog tractors shaped the German market at the same time; the Aulendorf company independently built smaller and medium agricultural tractors. This collective page holds three models – D47, Hela D 538 S and Samson 2 – with differing cylinder counts, showing the spread of the Aulendorf programme between the small and medium class.

The register lists 3 versions here with 8.1 to 16 kW from one- to three-cylinder diesel engines of 1,558 to 2,232 cc, kerb weights of 1,350 to 1,700 kg, lengths of 2,500 to 3,300 mm, widths of 1,040 to 1,540 mm and heights of 1,230 to 1,560 mm at 1,500 to 2,300 revolutions per minute.
Tractors of this size were common in the peasant farming of Upper Swabia and neighbouring regions, where small and medium holdings relied on nimble, cheap-to-run tractors for field and transport work, before larger and more powerful tractors came to dominate farms from the 1960s.
When buying a used example of these early Aulendorf models, the main points are the condition of the engine and injection pump, as spare parts for such small production runs are hard to find through regular trade, plus the condition of chassis, steering and brakes and corrosion on panels and mudguards; parts usually come from breakers or dealers specialising in historic agricultural machinery.

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.
