Wahl – other models: the collective page of tractors outside the named ranges, from the W16 type to the W225, 9 to 29 kW, single- to three-cylinder diesel engines
This page gathers the Wahl tractors the register could not assign to a named range. The type designation consists of the letter W and a two- or three-digit number, ranging from W16 and W17 through W70 and W80 to W133, W135 and W225; the span of displacements from 668 to 3,534 cm³ across one to three cylinders shows a line-up from small single-cylinder engines to larger multi-cylinder units.

The register lists here 16 versions with 9 to 29.3 kW (12 to 40 hp) from single- to three-cylinders of 668 to 3,534 cm³, unladen weights from 820 to 2,350 kg, lengths from 2,550 to 3,330 mm, widths from 1,570 to 1,880 mm and heights from 1,470 to 2,160 mm, at speeds of 2,000 to 2,600 rpm; throughout diesel-powered.
With a power range of 9 to 29 kW, the range covers the segment of smaller and medium yard and field tractors, designed for smaller farms and for work with light to medium implements. The spread of numbers in the type designations also suggests a line-up built up over a longer period rather than a single coherent generation.
On used examples, engine condition and compression, the state of clutch and gearbox, the tightness of the hydraulics, rust on sheet-metal parts and mudguards, and on the older single-cylinder types the condition of the starter motor or hand-crank mechanism all count; parts supply depends heavily on the specific model and year of manufacture.

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.
