ABSTRACT:
A method and apparatus for harvesting trees wherein a first log length bolt is delimbed by a movable delimber with the butt end of the tree clamped to put the tree trunk in tension during delimbing; and additional lengths are delimbed by the movable delimber with the top end of the tree clamped to put the trunk in compression during delimbing. The first log length is delimbed and bucked while the tree is held by the felling head of the harvester apparatus. Subsequent lengths are delimbed and bucked while the tree is held by a stationary clamp assembly. The delimber blades are used as a clamp to maneuver the tree after the first log length has been delimbed and bucked.
