ABSTRACT:
A processor clamp for a tree harvester. The tree engaging surface of a movable arm of the clamp is made up of two elements, a convex cam portion and a concave portion, to insure that all trees within the diameter range of the harvester will be clamped along a line either perpendicular to a downwardly angled, fixed tree engaging surface or tending to force the tree upward along the surface. The fixed tree engaging surface is adapted to penetrate a tree clamped thereon, but permits the tree to roll off into a bunk when the movable arm is released. The clamp assembly is easily removable from and attachable to the harvester to selectively use the harvester as a single tree machine or a multiple tree machine.
