Abstract
An apparatus adapted to permit independent setting of pitch and tilt of dozer blades without necessitating complex hydraulic circuitry or mechanical linkage. The blade is pivotally supported by two forwardly extending push beams. A strut is connected at one end to one of the push beams and is connected at its other end to the dozer blade via a cam assembly. The cam assembly permits dozer blade pitching to take place without interacting with the dozer blade tilt angle. In a preferred embodiment, two struts are used at opposite ends of the blade and are each connected to their respective side of the blade by a respective cam. The two cams are linked together and synchronized so that their stroke equally pitches the sides of the dozer blade.
