I remember as a kid that a guy was having a tree cut down near his house. It was a good sized tree - probably close to 24' in diameter maybe a little bigger. He had a 1066 International tractor that he tied a rope to in order to direct the tree but the tree drug that tractor with it right on top of the house - or should I say right into the house basically cutting it into. The lessons tie to something solid and push sideways on the rope to help start the tree moving and then get out of the way. If you do not know what you are doing - don't!
