Interesting. walt interested to hear your thoughts on that...I would be worried about it slipping either off the tree or the ground. I wouldn’t think you could feel very comfortable.
Never seen one of those before. Cool concept, but I'd be worried about a large/heavy back leaner rolling right off that thing.
Never seen a pusher but I was more impressed with how he had his winch set up and pulled that tree over with a lean in the opposite direction.
