Abstract: A power hitch has first and second frame elements interconnected for movement relative to each other about a vertical pivot axis. The first frame element is adapted for connection to a vehicle in a manner placing the pivot axis is to the rear of the vehicle. The second frame element is adapted for detachable connection to an implement to be towed behind the vehicle. The second frame element has a central axis extending rearwardly from the pivot axis. Extensible actuators on opposite sides of the central axis are pivotally connected at opposite ends respectively to each frame element. A suitable control system is employed to extend either one of the actuators while simultaneously retracting the other actuator in order to forcibly pivot the second frame element and the implement connected thereto about the pivot axis.

Abstract: An apparatus for detachably connecting a tool component to a frame component which is in turn adapted to be adjustably mounted on a vehicle. One of the components is provided with notched members for receiving engagement members on the other component. Contact members on one component are arranged to compressively engage resiliently compressible pads on the other component during entry of the engagement members into the notched members.
