Ilke this answer. I don't have those big straps, but I could use chains. Do clear your paths. This is a great strategy for this tree. On logs more vertical. I try to cut a notch 1/3 the diameter, on the underside, (compression) as high up as practical, then about 2-3' up from the ground, so you can run away; notch the topside (Tensiion) 1/3 through. Then alternately cut the top high up, and the bottom of the lower cut a litte at a time until it gives. This is so the log in the middle acts as a hinge, to control the tree as it comes down. The log in the middle guides the bulk of the tree to prevent, or slow any twisting or kicking sideways. (in theory). This is for junk trees where you are not trying to save saw or veneer logs. In that case, use moxiemaul's method.
2 1/2 years ago, I had half a dozen big, tall leaners after a storm. One was on the garage, in addition. The worst one was hung in a huge white pine at the center back of the garage. It would have smashed the peak of the garage if it came straight down. There was a small maple near the white pine at an angle that I thought could guide the top of the leaner away from the garage, if I cut the leaner just right. The maple was pushed partly over by a big tree that just missed the garage to he left. I used the hinge cut as described, and when I thought it was about to go, we got scared. I chained the log to the tractor and pulled. Cut a little, pull, cut a little, pull. Neither of us wanted to be around when the leaner let go. I finally got the hinge to work, and it came down safely, and the top slid down the maple, just as I had planned. The other leaners were simple. I like to do that hinge cut when they are 45º or more vertical. The butt of the log kicking sideways can get you, and even going straight out uncontrolled can be dangerous. Every leaner is a hazard.
To clarify, this top of this leaner was to the right of the big pine, and a normal cut would have crashed the leaner right on the peak of the already battered roof. By popping out the hinge, the top backed away from the white pine, so it could ride the maple down to the left. The top cut of the hinge was not as high as I would have liked it, but I made it work. Paul Bunyan could have cut it higher, and made a better hinge.. I've had smaller trees where I had to cut a second hinge to get the top to drop, when the first hinge didn't bring it down.
