As some know I had a logger take down my ash trees. He bore cut all of them. It all happened to fast to learn but the guy has been logging for 20 years and dropped 80 foot trees with pin point accuracy. He bore cut every tree and after googeling it, it is exactially what he told me. I'd love to learn it but will probably not try it. Anyone else use it? The loggers view on trees vs the tree service views on trees is quite different and interesting.
