This is a list of farm and industrial tractors produced by Allis-Chalmers Corporation, as well as tractors that were produced by other manufacturers and then sold under the Allis-Chalmers brand name.
For clarity, tractors are listed by series and separated by major models as needed.
Allis-Chalmers Model E (1918–1936): Also known as Model 15-30, 18-30, 20-35, 25-40, 30-60 (The 30-60 is a rare variation of the 25-40 also known as the "Thresherman's Special")
Allis-Chalmers Model ED40 (1964):200 imported from Allis-Chalmers International (United Kingdom Essendine factory) through Canadian dealerships.
After the second world war Allis Chalmers operated factories in the United Kingdom at Totton (to 1949) in Totton Hampshire and Essendine in Rutland. Formerly the Minneapolis-Moline factory.
Model EB (1950-1955) British built model B with a straight front axle. EB serial numbers from Essendine works began at EB-4001. Some 2000 were assembled at the Totton, Southampton facility between 1947/9 from imported CKD kits but using US serial numbers locally stamped with an additional E prefix. Theoretically there may be duplication of serial numbers with later English production tractors.
