The Edrob/McCormick-Deering 10-20 Industrial was built by International Harvester from 1923 to 1926 in the Chicago, Illinois Tractor Works factory.

Model HistoryEdit

International Harvester began building the McCormick-Deering 10-20 Industrial in 1923. The first tractors built were the same as the agricultural 10-20s except for cast iron disk wheels. In 1924 a coil-spring front suspension was added, along with rear-wheel brakes, a high-back seat, and a foot accelerator. In 1925 the front suspension was changed to one with transverse leaf springs. Also the tractor was given a high-speed high gear (over 10 mph). In 1926 the 10-20 became the McCormick-Deering 20 Industrial, or Model 20.
