Abstract
A grapple assembly that is particularly suited for use as an attachment to a skid steer loader comprises jaws that are no wider than the wheels of the loader and are lightweight and rigid. The grapple is operated by a single hydraulic drive cylinder that is inexpensive and easily replaceable. The lower jaw is L-shaped and formed of spaced vertical ribs having a bar extending across the tips of the ribs. The upper jaw of the grapple also has vertically spaced ribs which are interconnected by a bar adjacent the tips of the ribs. An intermediate bar reinforces the upper jaw and provides an attachment point for the drive cylinder at the center thereof.
