The Fordson Tractor
The Fordson Model F was the first lightweight tractor in the world. It went into mass production in 1917 and sold for $750. The original Fordson used a 20 horsepower, four-cylinder oil engine, and a three-speed transmission with speeds ranging from 2¼ to 6¼ mph. By mid-1918, more than 70 percent of the farmers were using these tractors.
