Abstract: An apparatus and method of installing a shank onto a ripper assembly of a tractor or crawler. A rotating shank installer (RSI) is welded onto a front face of a ripper assembly of a tractor, e.g., on the outside surface of a pocket beam. A portion of the RSI is allowed to rotate with respect to the pocket beam.
