Three Point Hitch The three point hitch was developed by Ferguson in the early part of the 20th Century. Ford put the hitch on the 9N in 1939 and little has changed in the design to this day. Other companies tried different hitches but the three point hitch became the favored design. This hitch is now standard on almost every tractor. The three point hitch consists of two lower links and an adjustable top link. The lower links provide lift for the implement and the top link adjusts the pitch of the implement. The three point hitch makes implement changes quick and easy. Perhaps the biggest advantage of three point hitch is its standardization. All implements use the same hook up. Unlike lawn tractors that have implements unique to each model, the three point hitch is universal. This allows the tractor owner to purchase implements from any one, regardless of brand that, properly sized, will fit his tractor. There are sizes of three point hitches. 0, I, II, III are the most common. Category I (approximately 20 - 50 hp) is the standard compact tractor hitch. Obviously, not every implement will fit every tractor. Horsepower and three point hitch capacity will play a roll. What size implement will work on a given tractor is dependant upon the tractor and what performance the owner requires. Usually if the tractor will lift an implement and the implement will cover the width of the tractor tires it is a good match. Rakes and blades should be a foot, or more wider than the tractor so that they will cover the tracks when the implement is angled. In Maine we typically have granite and clay. This does not make rototilling easy. Rototillers will offset to one side and are typically slightly narrower than the tractor. |
