Took down tree big oaks today and used a rope to guide them, the first one was picuture perfect and the tree was solid. Got to the second on and had the guide rope on it the started the face cut and no more than 2 inches in it was pinching the bar, this one if rotten inside. Got the face cut done and started on the back cut and this tree was 36 inched in diameter and got 8 inches in the it was lifting and one side ripped of and the other side pulled up and broke some stump. Most of the tree was junk. Thanks to the rope it went the way it was suppose to and all is well. Got some pictures for ya.
