Henry Ford began experimenting with tractor design in the early 1900s, establishing Fordson. While Ford stopped tractor production in the United States in 1928, it was continued in England. The Ford 800 series of tractors consists of the 820, 850 and 860 models. The 820 was produced between 1955 and 1957, and the 850 and 860 were produced from 1954 to 1957.
