For the actual felling, only one half of the screen stays open so that the remaining hydraulic power is available for the actual felling job. Unlike existing solutions where a protective screen is suspended from a forwarder, this solution offers the advantage that felles are not working under an unpropped crande. Another advantage is that the new screen is used in conjunction with a tracked tractor, which is less expensive to operate than a forwarder. Hall 26, Stand 22
