Allis-Chalmers

The III Series of the D10 & D12

Allis-Chalmers  introduced its “D” series tractors in 1957, starting with the D-14 and D-17. In 1959 the company added the D-10 and D-12 tractors to the line-up, essentially replacing the model “CA” and “B” tractors. The D-10 and D-12 were identical in size and horsepower (about 30 hp), the only diffence was wheel tread. The D-10 was designed for one-row cultivation, while the D-12 had adjustable wheels and axles for two-row cultivation.  Both tractors were also available in high-clearance models. The Allis-Chalmers patented Snap-Coupler hitching system came standard, but the 3 point hitch was an option. Production of the two tractors ran from 1959 to 1968, and the company produced just over 9,000 total. Allis-Chalmers improved and modified the tractors during the 9 years they were built, which was designated by three separate series.
