Abstract: A system for uniformly erasing soil indentations made by the wheels of agricultural equipment. The erasing elements are pulled behind the wheels of the agricultural equipment and are pivotally attached to the frame thereof thereby preventing the relative distance between the frame and the soil from affecting the depth of penetration of the erasing elements. The eraser elements are arranged such that they engage the soil behind the wheels of the equipment and penetrate the indentations to a depth which is largely determined by the weight of the eraser arm assembly, the consistency of the soil and the forces experienced by the erasing arm as it engages the soil. Accordingly, the cutting depth of the eraser arms are largely unaffected by the unevenness of the terrain. A structure is presented for lifting the eraser system from the soil so that the system may be transported to and from the location of use.
