Except that Prokop cut the SUPPORTING tree. Which means he was standing under the tree that was hanging....
I have a couple of hanging trees. I can only think of a couple of ways to do it. I am scared to do it so they continue to hang since they are out of the way. I have been hoping Momma Nature would take them down but so far she has not had the time. She did bring down a big sweat gum that was bent over last week. I was going to cut that gum tree down this fall or winter but Momma did it for me. I wish she would take down the hangers. I think I'm going to girdle one of them, cut some wedges out top and bottom to see if Momma can take the tree down with a little help.
Short of a crane, its do it this way, use heavy equipment to push/pull, or use a cable/strap/winch to pull the tree as its cut. None of those approches sound real fun... But if momma fail then its cable, cut, and pull with a winch.
Later,
