ABSTRACT:
A blade assembly for hard earth road graders has a support frame for attachment to the mouldboard of the road grader and a plurality of evenly spaced picks located in sockets spaced along the lower edge of the support frame. The picks have spigots to releasably locate in the support frame sockets and engage with the support frame to prevent relative rotation between the spigots of the picks and respective sockets. The picks each have a tungsten carbide tile attached to their front face with a straight transverse cutting edge along the lower edge. In use the working face of the picks is perpendicular to a road surface to achieve a shaving action.
