ABSTRACT:
The improved automatic ripper reset mechanism of the present invention includes a punch fixedly disposed on the distal free end of a ripper blade head for downward arcuate motion in response to the ripper blade striking an obstruction, a die having a matching contour surface, an incrementally fed shear bar disposed opposite the punch for fixed engagement between the punch and the die when the reset apparatus is in ripping functional position, and to be sheared off when the reset mechanism is sprung, a reset mechanism frame supporting a spring loaded push block means for incrementally advancing the shear bar, brake means for preventing expulsion of the shear bar from the frame by the push block means when the reset mechanism is in sprung position, and torque storage means for receiving torque during the springing of the reset mechanism by means of striking an obstruction and for retransmitting the stored torque to reset the mechanism.
