Abstract
A circuit for controlling pitch and tilt of a dozer blade in which two cylinders are connected between the dozer blade and the dozer push arms. One cylinder only is extended and retracted to achieve tilt, and both cylinders are operated in unison to achieve pitch with divider valves assuring that equal volumes of hydraulic fluid reach each cylinder and are expelled from each cylinder. Extension and retraction is selectively determined by a directional control valve, while a selector valve determines whether both cylinders or only one cylinder is connected with the directional control valve.
