There are many types of 3-point hitch implements that can be attached to a tractor using the three-point hitch system. History The modern three-point hitch began with experiments by Harry Ferguson in the s and s. The distance from the tail of the PTO shaft to the lift arm ends is approximately 14 inches. The higher category hitches have sturdier lift arms and larger connector pins. Three-point attachment is the simplest and the only statically determinate way of joining two bodies in engineering. The 2 outer hitch arms provide lifting, lowering, and can be adjusted to tilt an attachment, such as a plow. The implement is secured by placing a pin on the ends of the posts.

Comparatively very little rearward force is applied from the top link unless the implement becomes bound up or twisted in some way.
The primary benefit of the three-point hitch system is to transfer the weight and resistance of an implement to the drive wheels of the tractor. Chances are if you own a tractorit is equipped with a three point hitch. Namespaces Article Talk.
