A multi-blade soil handling unit comprising a frame having rearward and forward ends with a pivotal hitch mounted on the forward end of the frame for connection to a prime mover. A transversely extending axle is mounted on the frame and is provided with a pair of ground engaging wheels on opposite ends thereof. A front blade is mounted on the frame forwardly of the wheels and a rear blade is mounted on the frame rearwardly of the ground engaging wheels. A second hydraulic cylinder is connected to the axle and the hitch to pivot the hitch with respect to the frame to permit the selective shifting of weight between the front and rear blades. The blades are normally disposed at opposing angles and are each individually angularly adjusted with respect to the frame and are each laterally adjustable with respect to the frame. The ends of each of the blades may also be raised or lowered by means of shims. |
