A Biojack 450 tree shear is an excellent device for first thinning, tree felling in complicated areas, windthrow handling, and harvesting energy wood. In municipal applications the grapple can be used, for instance, for clearing roadsides and parks, next to buildings and powerlines.

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.

Due 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 felling grapple ensure that stumps are cut low and that the cutting result is neat. The grapple closes firmly around the tree before the cut, for maximal safety in urban felling.

The Biojack 450 energy wood grapple features tough log grabs.

The optional secondary upper grapple (EG-kit) is fitted with delimbing blades for removing branches on trees before the cut. The EG-kit also enables full tree vertical moving for bigger diameters, before felling.

The accumulation grapple (E-kit), for collecting several stems before loading, is an option to optimize and speed up the energy wood harvesting.
