You could also use a throw line if there are any branches left on the dead standing... Aim high on the side opposite that which you want to to fell toward, run a "fishing line" type system down to the base of the tree and tie it off. Then you can put a man or machine on the loose end. This will ensure that the tree doesn't tip the wrong way and still gives you the advantage of having a "directional anchor" on the loose end of the rope. Of course, notch and cut accordingly... A throw line allows you to get a rope high into the tree without climbing it, which is nice if the tree is dead.
