Several years ago I needed to fall about ten mature pines at my lake property to make way for the new cabin. My son and I used a rope-and-pulley system in concert with my truck to pull the trees over. Doing it this way, nobody was any where near the tree being felled, and it gets the whole tree, including the roots out. Over the years I have used this method on some fairly large girth trees, the secret being to get the rope (with the top snatch-block) as far up the trunk as possible. Placement of the snatch-blocks will also give you good control of where the tree will land.
