Abstract: A blade for a bulldozer. The blade comprises a post of variable, substantially circular cross section varying from a maximum at the top and the bottom uniformly to a minimum at the middle. The post is attachable to a bulldozer. A blade member is pivotally mounted to each side of the post. Each blade member is shaped at its inner end to correspond to the shape of the surface of the post. The blade is adapted to attach to, for example, hydraulic rams to pivot each blade member independently about the post. Thus, upon pivoting, each blade moves around the post while at least maintaining a uniform, small distance from said post.
