Housed in the Ford museum in Dearborn, Michigan, is the prototype Ford 9N tractor. This was the first Ford tractor to be developed with the Ferguson System. Henry Ford turned the first furrow with this in April 1939, on his own farm at Dearborn. The tractor weighed 2,100lb. It was a considerable design advance on the Ferguson-Brown tractor (the production version of the Ferguson Black) and, after the war, followed by the ubiquitous TE and TO series of grey Fergusons.
