ABSTRACT:
A dozer blade mounting for a dozer frame having a dozer blade movably supported thereon includes at least one rigid link that has one end pivoted on the vehicle frame and the opposite end pivoted on the dozer frame with fluid ram means associated with the vehicle frame and dozer frame for raising and lowering the blade and dozer frame and angling the dozer frame and blade with respect to a horizontal reference plane. In one version of the invention, two separate links are universally connected at opposite ends to the dozer frame and the vehicle frame and a pair of independently actuated fluid rams are interposed between the dozer frame and the vehicle frame to produce the raising and lowering as well as the tilting of the blade with respect to the vehicle. In another version, the rigid link is raised and lowered through a fluid ram between the link and the vehicle frame and a second fluid ram is interposed between the link and the dozer frame to produce the tilting of the blade.
