A self-powered and remote-controlled log grappler with a bar saw that can cut up to 36 inches in diameter. Designed to be suspended from a mobile crane, so that the operator of the mobile crane can reach up and safely position the grappler around a section of a tree and severe that section. Then lift out of harm’s way and safely lower the section removed to the ground, without the need for a climber to hoisted up in the tree to choke and cut. The PowerGrab 3600 can also be used to just grab a tree and then have it cut at ground level by a chainsaw operator, allowing a crane to again be utilized without manual choking. Design for backyard and other difficult trees, eliminating or reducing the need for bucket trucks and sky lifts while providing a much safer and more productive alternative.
