A tree harvester (12) is provided with an apparatus (20) for accumulating trees, one at a time, The apparatus includes a single, multiple accumulator arm (58) which has three joined members (30, 40, 50). A first member (30) is pivotally connected to the frame (18) of the tree harvester (12) and the second member (40) is pivotally connected to the first member (30) and movable relative to the first member (30) between an open position and a closed position. The second member (40) is maintained in one of the open and closed positions during pivotal movement of the first member (30). A third member (50) is pivotally connected to the second member (40) and biased so that it can be folded and removed from between a tree (26) and the frame (18) and unfolded to later accumulate trees against the frame (18). This simple structure uses only one movable accumulator arm (58) instead of two. |
