Allis-Chalmers W series – WC, WD, WF and WD-45 from Milwaukee, 1930s to 1950s: the classics with four- and six-cylinder engines, 18 to 28 kW
The W series was the backbone of Allis-Chalmers tractors from Milwaukee, Wisconsin, between the 1930s and 1950s. The WC, built from 1933, was among the first tractors offered from the factory on rubber tyres instead of steel wheels and contributed substantially to the spread of rubber tyres in agriculture; the WF was the wheatland and industrial version. The WD of 1948 brought the adjustable Power-Shift rear axle and the hydraulic Traction Booster, and the WD-45 of 1953 was its further development with live PTO and hydraulics on the move.

The register lists here 4 versions with 18 to 27.9 kW from four- and six-cylinder engines of 3,295 to 3,707 cm³ displacement, unladen weights from 1,501 to 1,794 kg, lengths from 3,099 to 3,521 mm, widths from 1,422 to 1,727 mm and heights from 1,384 to 2,070 mm; the fuels recorded are petrol, low-octane tractor-grade petrol and, on the WD-45, also LPG and diesel.
The W series made Allis-Chalmers, alongside International Harvester, John Deere and Ford, one of the defining American tractor brands of the post-war period and was especially common on family farms across the American Midwest.
Used, the W classics call for checking engine and carburettor condition, originality of sheet metal and paint, the condition of the Power-Shift mechanism on the WD and WD-45, and tyres and the ignition system; parts for the W series are offered by specialist vintage-tractor dealers and reproduction-parts makers.
