The McCormick-Deering 10-20 was built by International Harvester from 1923 to 1939 in the Chicago, Illinois, USA Tractor Works factory.
Model History[]
The 10-20 looked much like the McCormick-Deering 15-30 but was considerably smaller. With its 2-plow rating it replaced the International 8-16. The engine was a 284ci ohv 4-cylinder governed at 1,000 rpm, coupled to a 3-speed transmission. In 1928 the 10-20 was given slightly more power by increasing the governed rpm to 1,025.
The 1918 Fordson turned the tractor world upside down with its front-radiator automotive styling, unit construction, light weight, 251 ci 4-cylinder engine, 3-speed transmission, and mass-production methods to keep the price down. Also in 1918 International Harvester brought out the sloped-hood International 8-16, with the same size engine as the Fordson and a 3-speed transmission, but it was quite a bit heavier and with a higher initial price of $1,150. The International didn’t sell nearly as well as the Fordson despite price cuts to make it more competitive. International’s real Fordson-fighter, introduced in 1923, was the very modern (for the day) McCormick-Deering 10-20. It was priced at $785 and was an immediate success. The 10-20 stayed in production until 1939. Sales dropped off in the later years after the company brought out the newer McCormick-Deering W-30.
