ABSTRACT:
An angle adjustment mechanism for an implement mounted on a vehicle, such as a bulldozer having a C-shaped frame which pivotally supports the dozer blade at the forward end of the vehicle for angled movement. The side frame portions include slide members mounted on rails which are pivotally interconnected with one of the opposed sides of the implement. The rails each include a plurality of spaced horizontal slots or openings at predetermined locations, and the channel-shaped slide members each include a downwardly opening slot which is alignable with one of the openings in the rails. The slide members are locked to fix the angled position of the implement by horizontally oriented tapered anchor pins receivable through the slot in the slide member and one of the aligned openings in the rails.
