A piercing tip assembly has two piercing tips, each having two sets of piercing and shearing edges. The tip is reversible so that the tip can be detached from the shears, its orientation changed, and replaced on the shears so a fresh, sharp set of piercing and shearing edges is exposed during use. The tips are reverse by rotating each tip and replacing the tip mounted on the right side of the jaw, and switching the tip on the left side of the jaw to the right side, and the tip on the right side of the jaw to the left side. The piercing tip assembly protects a substantial portion of the upper jaw of a metal shears from wear.

A connecting and adapting system for interconnecting a pair of jaws of a grapple assembly and for adapting the grapple assembly for connecting to a plurality of linkages. The system includes bearings, where the bearings have a flange, an elongated section, and a bore. The flange of the bearings abuts a portion of one of the jaws, the elongated section of the bearings interconnects the jaws, and the bore of the bearing receives a pin to provide a connecting location. A portion of the bearing, being positioned opposite the flange, receives a collar that abuts a portion of one of the jaws.
