Abstract
An adjustable hitch device for coupling a towing vehicle to a towed implement or trailer is adapted for changing the coupling angle between the vehicle and the implement and also for changing the elevation angle of the implement. An elongated, rigid link is pivotally coupled at a first end to a hitch mechanism coupled to the vehicle and at a second, opposed end to a forward portion of the implement. An intermediate portion of the link is pivotally coupled to one end of a hydraulic cylinder, while a second, opposed end of the hydraulic cylinder is coupled to a forward portion of the implement. Extension of the cylinder lowers the implement's forward portion and raises its aft portion, while retraction of the cylinder has an opposite effect. In this manner, the height of the implement may be increased for use in operation or may be lowered for transport or storage.
