I pulled about a half dozen 3" trees in my backyard last summer. I used an electric winch. The only thing I did different was to put a metal pole with a plate I welded to it at a 45 degree angle against the tree. I then draped the wire up over the post down to the base of the tree, where i looped it a couple of times and hooked it. this way when I pulled back it also pulled up. It seemed to work better (in my mind). Physicist please feel free to argue.
