ABSTRACT:
A tree with a harvester head includes a frame having a cutting area defined thereon and an accumulator area adjacent the cutter area with accumulator arms on the frame for holding the trees in the accumulator area and grapple arms for gripping a growing tree between the accumulator arms and the grapple arms. The arms are arranged such that the growing tree can be gripped between the closed accumulator arms and grapple arms during the cutting operation and then the accumulator arms can be opened to allow the grapple arms to automatically move the severed tree into the accumulator area in which it is then retained by the accumulator arms.
