Abstract

A felling lever combined with turn hook 14, whose function is to grasp a tree trunk 23 or log for turning of it, has a flexible fastening arrangement for the hook consisting of a wire 16 and a rubber spring 21 connected to it. At the inner end of the wire there is a bulldog clip 20 which stops the wire from being pulled out from the felling lever and at the outer end the hook is attached. When the wire is free, it is automatically pulled into the hollow shaft 10 of the felling lever. <IMAGE>
