Abstract
A device is set forth for trimming branch and frond segments from trees which includes a frame positionable about the trunk and a mechanism disposed on the frame for driving the frame upwardly and downwardly along the trunk. A carriage is carried by the frame and encircles the trunk. Trimming blades are mounted on the carriage in a horizontally opposed chordal relationship and are biased to maintain engagement with the trunk. As the frame is driven upwardly, a motor rotates the carriage causing the blades to remove the branch and frond segments from the tree.
