They were not designed to be backed up at all and backing them up could bind them up to the point of breaking.Īnd possibly the most important, because traction is directly related to tractor weight, tractors were required to be heavy enough to create the traction required for tillage.īy creating the draft sensing three-point hitch Henry Ford and Harry Ferguson solved all three of these major problems. Second, implements such as gang disks and many three-bottom plows could not be backed up. My son, Will, running our 1948 Minneapolis-Moline UTU tractor and pulling a John Deere model 66 mechanical lift drag plow In the case of the draw plow, often the only option was to detach the tractor from the plow and try to pull it out backwards. These mechanical lifts worked fine in perfect conditions, but should the tractor get stuck they were incredibly difficult to deal with.
Unfortunately, in the 1920’s and 30’s there was really only one way to attach machinery by the drawbar.ĭrawn machinery worked, but it had several limitations.įirst, because the tractors of the time did not have remote hydraulics, plows and other machinery required forward movement to actuate the mechanical lift.
I think that we take the three-point hitch for granted today because, for most of us, it has been around our entire lifetime. I know this post was supposed to be about draft control, but I couldn’t help throwing in this tidbit of info as well. Thanks to an argument over his patent, Ferguson began making his own tractors in 1948, and by the mid-1950s all American tractor manufacturers offered a utility tractor with draft sensing three-point hitch. Thanks to a handshake agreement, Henry Ford used Ferguson’s design to create an entirely new type of tractor that had worldwide appeal, the utility tractor.ĭraft control is the ability for a tractor to adjust the depth of its three-point hitch based on soil conditions and engine power output. What made the 1939 Ford 9N tractor revolutionary was the draft control system that had been designed by Harry Ferguson. Although the Ford 9N tractor is known for being the first widely sold tractor with an integrated three-point hitch, it was not the first.
