Output of the recorded models ranges from 8.1 to 22.1 kW, with models rated in horsepower from 11 to 30 hp, using one- and two-cylinder engines with displacement from 636 to 3,882 cm³.

Recorded operating weight runs from 800 to 2,040 kg, wheelbase from 1,550 to 2,200 mm, and top speed of the listed models spans 12.8 to 20 km/h.
The A series targeted smaller farms needing a simple, compact tractor. For a used model, the exact production year matters most, as the A series developed considerably over more than two decades, from pre-war designs to post-war models such as the AB.
The fuel types noted in the register, diesel as well as wood and peat, point to the war and immediate post-war period, when diesel shortages in Germany forced tractors to run on wood-gas generators or peat as an emergency measure; such conversions needed an additional gas generator and considerably more upkeep than plain diesel operation. For the PTO, these early small tractors followed the simple 540 rpm standard. After the war, fuel supply normalised, and later A-series models ran on diesel alone once again. The simple electrics of these early models are also worth a look when buying.

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.
