MOTOR GRADER BLADE ASSEMBLY A B S T R A C T A blade assembly for a motor grader has a moldboard with longitudinal reinforcing channels close to its upper and lower margins, and a reinforcing plate between the channels with spaced upright ribs between the moldboard and the plate, so that the whole assembly is like a reinforced box beam of which the moldboard forms one side. In addition a lower reinforcing member extends along the lower marginal portion of the moldboard, and end reinforcements extend very close to the lower corners of the moldboard and the blade. Top and bottom mounting and side shift rails are welded to the rear of the channels, and forces on the blade are transmitted almost entirely through the lower mounting rail which has a wide planar top surface for transmitting vertical working forces. Both rails have planar rear surfaces of substantial height for transmitting horizontal working forces.
