A Biojack 300 energy wood grapple is an excellent tool for primary thinning, felling of trees in problem areas, clearing away windthrow, and harvesting energy timber. In municipal applications the grapple can be used, for instance, for clearing roadsides and parks.
Thanks to the movable blade, felling and loading can both be performed without any special modifications. There is no need to remove the blade for loading; in the loading position it is securely stowed away inside the frame.
Installation is easy and swift; no additional hydraulics is required, other than a pressure and a return hose. The technical features of this Biojack grapple ensure that stumps are cut low and that the cutting result is smooth.
