The HK Ex frame has advanced maneuvering qualities when you need to maintain branches in tall hedges or want to keep a straight top line of the hedge itself. The trimmer bar can be varied infinitely up to 195° which enables you to work with a horizontal angle. Moreover, you can transverse the trimmer bar up to 90° of the direction of work, thus allowing you to maintain this direction even when the frame is turned forward. In this way you will be able to reach in between the trees for cutting single branches if needed.
