An earth moving appliance comprises a frame equipped with caterpillar tracks so that it can be moved. A turret is mounted on the frame for rotation and has a working attachment mounted thereon, the working attachment including a working tool such as, for example, a bucket. An arm is mounted by one end on the turret and carries on its other end a blade. The position of the arm may be altered so that in one position the blade will bear against the ground. The blade extends transversely to a plane of movement of the working attachment and is disposed between the working tool and the frame.
