Ford’s 9N was light, small, less expensive than most of its competition but what made it revolutionary was Harry Fergusen’s hydraulic-controlled Three Point Hitch system. Up to this time the various tractor manufacturers used different methods of implement attachment. The changing of implements, which were heavy, usually required more than one man to perform but with the Fergusen System the farmer could back-up to the implement, attach at three points with pins, lift the implement by use of hydraulic arms and move on out to work. At the field, the implement was lowered to the ground, again hydraulically, and its design geometry would control the depth of soil penetration referred to as draft.The hitch also prevented the tractor from flipping over backward which had been a problem with the Fordson. Farmers could even share implements with their neighbors to reduce their operating cost.
