The cut is assured by the chainsaw. After the cut, the saw bar is into the grapple’s chassis, allowing the wood handling.

Thanks to the tilt, the grapple can be used for felling and for loading logs.

Three hydraulic lines are required (pressure and return). The chainsaw is activated with an electric command in cabin, which require an electric cable or wireless control for limitless rotation.
