Abstract
This invention provides a mounting arrangement for a ripper shank that is mounted in a channel defined in a ripper frame. A pair of piston members are mounted in the frame on opposite sides of the ripper shank. The piston members are urged into engagement with the ripper shank by a biasing mechanism that is positioned between the frame and the piston members. An actuating mechanism is mounted between the frame and the piston members to disengage the biasing mechanism to allow the adjustment of the ripper shank with respect to the frame in one of an infinite number of positions.
