The Allis-Chalmers WF is the shorter, narrower and lower sister version of the WC and appeared alongside it in 1937. Its design was revised in 1940, and it was built until 1951 in West Allis in the US state of Wisconsin. As a standard-tread tractor with rear-wheel drive it was meant for row-crop work as much as for general field work.
Power came from an Allis-Chalmers four-cylinder gasoline engine of 3.3 litres, which gave about 22 hp at the PTO. Tractordata gives the weight as 3,175 lb, and the wheelbase is 70 inches. The front wheels have 5.5x16 tyres, the rear 11.25x24. The tractor pulled two ploughs of fourteen inches cutting width each.
The price is interesting: in 1951, the last year of production, the WF cost 1,340 US dollars at the factory. It thus stood for an inexpensive, simply built tractor of the kind American farms wanted before larger models spread.
Allis-Chalmers – other models: the collective page of the orange tractors from Milwaukee outside the named ranges, from the 10-18 and 20-35 through the letter models B, C, WC and WD to the 100s (170 to 220)
This page gathers the Allis-Chalmers tractors the register could not assign to a named range – the brand from Milwaukee, Wisconsin, that began in 1914 with the 10-18, was the first maker to introduce pneumatic tyres on a tractor with the Model U in 1932 and created the affordable small tractor for the American family farm with the Model B of 1937, before being sold to Deutz in 1985. The type logic: the early number types 10-18, 12-20 and 20-35 give drawbar and belt power in hp; the letter models A, B, C, CA, WC and WD of the 1930s to 1950s denote model types, not size; the D series (D-10 to D-21) of the 1950s and 1960s orders in ascending order; the 100s (160 to 220) of 1964 to 1975 give roughly the hp class, XT the turbocharger; the 7000s (7010 to 7080) of the 1970s with the Acousta Cab and the 8000s (8010 to 8070) of the 1980s are the last own ranges, the 4W-220 and 4W-305 the articulated tractors, the 5000s and 6000s bought-in compacts from Toyosha and Fiat. The engines are Allis-Chalmers' own as petrol, LPG and diesel versions, Perkins in some diesel models and Toyosha in the Japanese compacts.

The register lists here 115 versions with 6 to 305 hp from two- to eight-cylinders of 1,002 to 11,973 cm³, widths from 915 to 2,438 mm and heights from 1,191 to 3,531 mm.
From the 1930s to the 1970s Allis-Chalmers was the third big American maker after John Deere and International Harvester; the Persian Orange tractors are collectors' pieces today with their own association, and the brand lived on through Deutz-Allis and AGCO Allis until 2001.
On used tractors, originality, engine condition (carburettor on petrol engines, injection pump on diesels), clutch and transmission (Power Director on the D-17 and the 100s), hydraulics (Traction Booster) and sheet metal count; parts run through collector dealers and AGCO for the late ranges.
