Abstract: A clamshell attachment for a crescent shaped, concave-convex log grapple converts the log grapple to a scoop or bucket type device for handling bulk material such as wood chips. It consists of a pair of concave-convex scoops pivoted together at their upper ends. A holding pin connects each grapple half to a respective scoop, with the concave portion or side of each grapple half positioned over and adjacent the convex side of a respective scoop. The only modification required of the log grapple is the addition of apertured tabs to its convex sides, the tabs receiving the holding pins.
