Independently-adjustable shanks offering three positions each allow dozer operators to, as needed, shorten or lengthen the shanks on the DR3 "triple" ripper from Nye Manufacturing. The three-inch-thick steel shanks can be angled past the vertical in either direction, providing for the optimum ripping angle. Built entirely from extra-thick 44W steel, the DR3 ripper features a fully-enclosed box design engineered for strength.
