A three point tractor hitch permitting an implement to be attached or detached by an operator without leaving the tractor seat. The upper hitch arm includes a linear actuator with a hand grip and a hand operated switch controlling extension and contraction of the upper arm. A latching mechanism and a hand operated latch release are mounted on the upper arm facilitating attachment and release of the upper arm to an upper attaching pin of an implement hitch mast. One of the two lower arms of the hitch can be shifted laterally by a hydraulically actuated cylinder.

1. A three point hitch apparatus for connecting one of the forward and rearward ends of a tractor to an implement of the type having an upper hitch pin and a pair of laterally spaced lower hitch pins studs, said hitch apparatus comprising:a pair laterally spaced lower arms extending in a fore and aft direction relative to said tractor having first corresponding ends pivotally connected to said tractor and second corresponding ends adapted for connection to said lower hitch pins of said implement, each of said second corresponding ends of said lower arms presenting and an upwardly open jaw, a shiftable locking shaft reciprocably mounted on said second end of each of said lower arms and a pair of extensible and contractible hydraulic actuators mounted, respectively, on said pair of lower arms and connected, respectively, to said shafts whereby extension of said hydraulic actuators shifts said locking shafts to a position in which said lower hitch pins are locked in said jaws when said lower hitch pins are positioned in said jaws and an upper arm having one end pivotally connected to said one end of said tractor at a location above the connection of said lower arms to said one end of said tractor and a second end adapted for pivotal connection to said upper hitch pin of said implement.
