Abstract
A hitch assembly adapted to secure a trailer and tractor vehicle includes an elongated housing, a threaded shaft in the housing, a coupling member on the shaft, a carriage member secured to the coupling member, a rotatable drive that turns the shaft to advance the coupling member and carriage member, a first member secured to the housing for connection to one of the vehicles and a second member secured to the carriage for connection to the other vehicle. This allows the effective height of the hitch assembly to be varied so that different towing situations can be accommodated. In one embodiment, flat slide surfaces between the carriage and the housing are provided. A yoke assembly is also disclosed.
