ABSTRACT:
A tree clamp, especially for a tree length harvester, having a compact arrangement of a movable jaw which folds partially inside of a fixed jaw and has a pivoted section to clamp the tree. The movable jaw and its pivoted section also grasp the butt end of the tree and lift it out of the teeth of the fixed jaw at the end of the processing step. The tree is then released and free to roll into a storage rack.
An automatic sequence control is provided that includes a pivoted plate on the clamp which is depressed by the tree to initiate processing steps without requiring the operator's attention.
