  • Automatic feller/buncher clamp control
    Patent number: 6578610
    Abstract: A clamp control system for a feller/buncher has three buttons for automating the operation of the harvesting and accumulating clamps. A CLOSE button, when momentarily actuated for the first tree of a bundle, closes the harvesting clamp and the accumulating clamp and then re-opens the harvesting clamp. When actuated again momentarily for the second and subsequent trees, the harvesting clamp closes, the accumulating clamp opens and re-closes and the harvesting clamp re-opens. Actuation of an OPEN button opens both clamps and resets the system to be ready for the first tree of the next bundle. Actuation of a STOP/CANCEL button freezes both clamps in their current positions.
