ABSTRACT:
A shear mechanism includes shear members pivotally mounted to a first frame, with a second frame movable relative to the first frame, and first and second links connected to the second frame. The first and second links are also connected to the first and second shear members, and first and second cylinders are connected with the second frame and the first and second links respectively, so that actuation of the cylinders in one direction moves the links to bring the shear members together, and actuation of the cylinders in the other direction moves the links to move the shear members apart, with the second frame moving relative to the first frame upon such movement of the first and second shear members.
