ABSTRACT:
In an apparatus for de-limbing trees, there is provided a carriage moving longitudinally on a rail, and having a pair of de-limbing arms adjacent one end which are mounted for pivoting movement with respect to the carriage. Each arm defines a concavity adapted to pivot into contact with a tree held in an upper recess in the carriage, and there are means for urging the arms against the tree. Each arm has a first cutting edge along the forward margin and a second cutting edge along the rearward margin, the first cutting edge being offset inwardly with respect to the second, such that the first cutting edge after passing forwardly beyond the stump of a tree limb which it has severed, can shift inwardly to lie against the tree trunk so that the next cut is made as close as possible to the trunk.
