ABSTRACT:
Earth moving, ground leveling and land planing apparatus having a substantially rectangular frame which is pivotally attached at the back end thereof to a support member containing ground engaging wheels. A cutting blade is disposed laterally between the bottom sides of the frame, and a bucket having an open front end is provided with the forward edge of the floor of the bucket being mounted to the frame adjacent to the trailing edge of said blade. A blade support member extends from the back end to the forward end of the frame substantially along the longitudinal axis of the frame. A downwardly extending projection from the blade support member is integrally attached as by welding to the cutting blade at a position substantially intermediate the cutting width of the blade. The support thus provided intermediate the ends of the blade prevents the blade, which has a width of at least about 10 feet, from undesirable deflection due to the weight of the load of dirt in the bucket or to forces exerted on the blade from the ground.
