ABSTRACT:
In a tree handling device, where the tree is fed longitudinally through at least three drive wheels driven by a fixed-displacement hydraulic pump, feeding commences with all drive wheels simultaneously propelling the tree longitudinally through the knife arms and frame. During feeding, once the approximate maximum feeding speed of the drive wheels is achieved, one of the drive wheels is shifted to a free-wheeling condition, allowing the maximum feed speed to increase.
