 Improper hitching has caused many agricultural workers to get injured or killed. Loads for heavy pulling should be hitched only to the drawbar. Hitching to the axle or top link bracket could cause the tractor to flip over backwards very quickly. Make sure there are no loose chains, ropes, cables or hydraulic lines dangling from either the tractor or the implement. They can catch under wheel or on a stump or a large rock and cause a very sudden stop or loss of control. Since 1960 there has been one system so you can safely hook up any make of implement to any make of tractor. The three-point hitch is part of that system and includes the tractors hydraulic system, attaching points, the lifting arms and stabilizers. It gives the operator easy control over the implement. It transfers the weight and stress of any implement to the rear wheels of the tractor. Don't try to check the hydraulic connections for leaks using your hands. The oil can get quite hot and burn your fingers. If the oil is under pressure it can also penetrate your skin and cause a major injury. Use an index card or piece of cardboard. It will quickly tell you if and where there are any fluid leaks. The hydraulic system is the backbone of the tractors ability to do multiple tasks. Here are the points to remember. Loads for heavy pulling should only be hitched to the drawbar not the three-point hitch. Never hitch to the axle or top link bracket. Make sure there are no loose chains, ropes, cables or hydraulic lines where they can drag on the ground. Check for hydraulic leaks with a piece of cardboard never with your hands. Make sure the hydraulic lines are loose enough to allow the tractor to turn.
