  • Patent number: 4781129
    Abstract: A debris and soil shaver for no till farming is disclosed which has a disk-like member which floats up and down as it is pulled across the ground surface. The disk is angled with respect to a predetermined direction of travel of an agricultural apparatus which is adapted to pull the shaver. The disk is rotatably mounted to a first support member about a central transverse disk axis. The first support member is pivotally mounted to a vertical second support member about a pivot axis. The pivot axis and central transverse axis are angled with respect to one another. The second support member is clamped to the agricultural apparatus which pulls the shaver. With such a construction, pivotal movement of the first support member about the pivot axis causes the angle of the disk relative to the ground surface to change. The angle adjusting prevents the disk from engaging too much soil and allows the disk to seek a path of least resistance as it rolls across a planting field.
