Harry Ferguson 's tractor hitch is shown in 1922 as an aftermarket attachment mounted on a Fordson tractor. It is a fully mechanical version with a depth wheel (a small wheel that sets the plow depth). By 1926, Ferguson and colleagues had developed and patented the modern hydraulic three-point hitch . Ferguson sold his hitches and implements during the 1920s and 1930s and worked with David Brown to produce Ferguson-brand tractors. In 1938 Ferguson finally struck an agreement with Henry Ford to put Ferguson hitches on Ford tractors at the factory—something he had first attempted in 1920 and 1921 at Cork and Dearborn. Their 1938 agreement led to the Ford 9N .
