ABSTRACT:
A linkage arrangement is disclosed for connecting a dozer blade and pushbeams which reduces blade roll-back during lifting thereby making it substantially more difficult for dirt and the like to cling to the blade. The linkage arrangement includes a pair of leveling link assemblies which are mounted to the pushbeams on opposite sides of the tractor frame. An adjustable strut is connected between one of the leveling link assemblies and the upper edge of the blade, and a tilt cylinder is connected between the upper edge of the blade and the opposed leveling link assembly. As the blade is raised, the adjustable strut and corresponding leveling link assembly automatically force the blade into a relatively vertical attitude thereby reducing blade roll-back. Actuation of the tilt cylinder permits the blade to be tilted while the blade is being kept at the vertical attitude established by the leveling link assembly and adjustable strut. Thus, the linkage arrangement forces the blade to a relatively vertical attitude during lifting to prevent blade roll-back while still permitting the blade to be tilted.
