"To Fell a Tree was written for the professional tree cutter as well as the weekend woodcutter. It's loaded with practical information that is essential to the safety and success of any tree felling and woodcutting operation, whether it's in the forest or the backyard. With step-by-step methods and more than 200 illustrations, topics include preparations before the work begins, felling a tree using a three-step procedure, felling difficult trees, and limbing and bucking the tree."
