Huber & Wössner DL 6: single-cylinder diesel compact tractor from the DL series with evaporative water cooling, 400 cc displacement, 6.5 hp output and 500 kg weight, built 1953 to 1955
The DL 6 from Huber & Wössner was built between 1953 and 1955 and belongs to the family of small, simple field tractors that numerous smaller German workshops offered in the early 1950s for farms with a limited budget.

The single-cylinder diesel engine of 400 cc is cooled by water evaporation and delivers 6.5 hp at 2,000 rpm. At a weight of 500 kg, a length of 2,800 mm, a height of 900 mm and a width of 1,400 mm, with a wheelbase of about 1,900 mm, the DL 6 reaches a top speed of 15 km/h, well within the range typical of its class.
Evaporative cooling needs no closed circuit or radiator: the coolant evaporates at operating temperature and must be topped up regularly, which keeps the design simple but demands regular checking of the water level. A single-cylinder diesel this light was built for small farms and simple field tasks, not for heavy draught work.
When buying such an old and rare model, the condition of the water jacket and the evaporation opening matters most, since corrosion from within is a risk without a closed circuit. Also worth checking are compression and starting behaviour of the single cylinder, the clutch, and rust on the frame and sheet-metal parts; spare parts for such a small 1950s manufacturer can now practically only be found through collectors of 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.
