Wahl W – small tractors W 15, W 46, W 90 and W 98 with single- and twin-cylinder diesel engines from 10 to 18 kW, displacement 1,005 to 2,356 cm³, unladen weight between 880 and 1,485 kg
The W series brings together four small tractors: the W 15, W 46, W 90 and W 98 types. The type numbers after the W do not follow a continuously ascending sequence, but together cover a narrow power range in the lower segment. All four models are built as single- or twin-cylinder diesel tractors with comparatively small displacement, placing them in the light class of tractors listed here in the register.

The register lists four versions here with 10.2 to 17.6 kW from single- and twin-cylinder diesel engines with 1,005 to 2,356 cm³ displacement. Rated speed lies between 1,500 and 2,100 rpm, unladen weight ranges from 880 to 1,485 kg with lengths from 2,450 to 2,550 mm, widths from 1,500 to 1,570 mm and heights from 1,400 to 1,450 mm.
With unladen weights under one and a half tonnes and single- to twin-cylinder engines, the W series sits in the light yard-and-field tractor class, of the kind used on smaller farms and for specialty crops, where low weight and simple operation mattered more than high pulling power.
When buying used, with engines this small the condition of the injection pump and fuel system, tightness of the crankcase and valve cover, wear on the clutch and gearbox, and corrosion on sheet metal parts and wings are especially important to check. Parts availability for such small tractors is limited and runs mainly through specialist used-parts dealers.
