ABSTRACT:
A hydraulically operated hoof nipper of hoof trimming device comprises a pair of opposed C-shaped cutting blades mounted on first and second lever arms. The lever arms for the blades have two pivot points, a common one in the center connected to both blades and one on the outer end of each lever arm. The pivots on the outer ends of the lever arms are coupled through first and second adjustable-length control rods for adjusting the overlap on the blades to compensate for wear and the like. The opposite ends of the control rods are pivotally mounted on a frame and an hydraulically operated reciprocating control rod moves through the frame between the control rods to move the center pivot toward and away from the frame to close and open the cutting blades.
