ABSTRACT:
A feller buncher includes an elongate support having an axis, a first side, a second side, a first end and a second end. A first tree receiving cavity is positioned along the first side of the support. A second tree receiving cavity is positioned along the second side of the support. A circular saw is positioned at the second end of the support. The plane of the saw is transverse to the axis of the vertical support. Movable grapple arms are positioned on each of the first side and the second side of the support above the circular saw. The grapple arms are adapted to hold trees while they are being felled and then maintain bunches of felled trees in each of the first tree receiving cavity and the second tree receiving cavity.
