Gonna disagree a little, and actually maybe backtrack the thread a little to define some terms. "Pulling" a tree, if done properly, is really just using a lateral force in the top of a tree to shift the center of gravity rather than a lifting force at the base. The goal should be the same, merely to shift the center of gravity in the intended direction of fall. A rope in a tree, whether attached to a truck or any other type of mechanical advantage, be it a comealong, pulley system or what have you is no substitute and will not make up for improper cutting techniques. If your pulling a tree and it twists off the stump, it was probably a result of bad cuts, not the pulling location. Jeff
