Abstract

A tree delimber having a boom slidably mounted in a sleeve and means for moving the boom relative to the sleeve. Tree feeding means are mounted on the sleeve, movable between a closed tree feeding position and an open tree receiving position. There are tree gripping arms on the front of the boom and tree delimbing arms on the front of the sleeve. Both gripping and delimbing arms can be selectively positioned in one of: a tightly closed position to clamp a tree; an open tree receiving position; and a lightly closed position to loosely hold a tree. As the tree feeding means move a tree past the delimbing arms to delimb it, means are provided for sensing any stoppage of tree travel. On sensing stoppage, means initiate gripping of the tree by the delimbing arms and delimbing of the tree by the gripping arms. The invention also covers a method of delimbing with the above machine.
