ya I have done the safety proceds and yes les I do have a full harnes that is on at all times I also have a rope man on the ground I tie the rope around the tree in case my one of two ropes attached AROUND the tree breaks he has me suspended in the air. same as if I get weak with the saw I can just sit back in the harnes and he has me suspended. still a dangerous job but I have done this many time before just not for this kind of money. always having safety first.
