Abstract:

A hitch assembly is disclosed for use with endless track land vehicles that allows an implement mounted by a three-point hitch arrangement up to about 15 degrees arcing movement off the longitudinal axis oriented in the direction of travel of the land vehicle. A pivotal mounting means is connected to two horizontal arms which are joined at the rear by another member. The mounting means and connecting arms form a four-sided polygonal structure which can be raised or lowered by a hydraulic ram since the arms are pivotally connected at the corners. Finally, a telescoping linkage assembly, after the hitch assembly has been raised through 75 percent of its travel, urges the implement mounting means on the rear vertical connecting arm into a common, pre-selected travel position.
