Abstract: A fifth wheel hitch plate assembly adapted to be mounted to a vehicle frame includes a hitch plate component coupled to the frame by a vertical lift component. In one implementation, the vertical lift component includes at least four linkages that are pivotally connected to the hitch plate component and pivotally connected to the vehicle frame, wherein the four linkages operate, together with one or actuating members, to elevate a fifth wheel hitch plate assembly in a vertical or substantially vertical path, i.e., a path substantially perpendicular to the vehicle frame.

Abstract: A quick-attach mechanism for attaching an implement to the forward end and/or rearward end of a vehicle, such as a tractor used in a tractor-trailer combination, and the like. The quick-attach mechanism includes two laterally positioned female quick-attach sockets on the forward and/or rearward end of said vehicle. The quick-attach mechanisms can be formed into the chassis of the vehicle.
