  • Patent number: 4382457
    Abstract: A tree harvester comprising a mobile frame having a carriage with limb-stripping knives thereon which encircle the tree alternatively in snug or loosely-engaging relation, tree clamping means above the bed of the frame and saw means movably mounted on the clamping means for movement therewith and, in addition, between retracted position and lowered tree-sawing position. Selective rotary log-ejecting means is mounted adjacent the saw to eject the severed tree sections to either side, as desired. The limb-stripping knives progress the stripped portion of the tree beyond the saw and clamping means when in snug position, and strip the limbs off the tree when in loosely-engaging relation as the carriage moves away from the clamping means and saw.
