ABSTRACT:
A dozer blade mounting assembly for angling and tilting the blade, while preventing or adjustably limiting pitching, without inducing stresses in the assembly. The blade is supported on a conventional C-frame by a universal connection in the longitudinal axis of the vehicle. The mounting assembly includes a mast assembly connected to the frame midportion and extending upwardly from the frame, a pair of hydraulic angling cylinders connected between the side portions of the blade and the mast assembly adjacent the longitudinal axis of the vehicle, a tilt cylinder connected between the frame and the mast assembly and a bracket assembly supporting the upper portion of the blade and preventing or adjustably limiting pitching of the blade. The bracket assembly includes a bracket member having an elongated slot extending generally parallel to the blade and a slide block having a width substantially equal to the width of the slot which floats within the slot to allow tilting of the blade, but preventing pitch of the blade.
