Abstract: An earth moving machine attachment is disclosed comprising a plurality of disk units mounted to a disk unit mounting beam which is fixed to a beam pushing frame for pivotally coupling to a dozer or tractor C frame. The beam pushing frame is angled obtusely in a clockwise or counterclockwise direction from the direction of push by a pair of reciprocal operating hydraulic cylinders to grade the earth materials to one side or the other of the C frame. The disk unit mounting beam and attached disk units are hingedly connected to a parallel offset shaft of the beam pushing frame for tilting the disk blades to provide restricted floatation on the earth materials. A sliding feature of the hinged connection between the disk unit mounting beam and the beam pushing frame accommodates hydraulic power means of shifting the load relative to the pushing axis of the earth moving machine.
