Sheave block mechanical advantage?

[PILOON]

The trees are dead ash about 10 in. at the base, and maybe 30 ft. tall. They are close to the road and I don't want to fell them in the road. I am going to fell them parallel to the road. I could probably do it with no "persuasion" , but I want to be sure. I have used my sheave block many times on trees much larger than these. I understand the dynamics of the energy stored in a tree, I would never try to force a tree to go where it flat won't go. I wear chaps,forestry helmet,ear and eye protection,steel toed boots, and always make sure I have a clear escape route. Yes I have seen the videos, the idiots and also the informative how to videos from Stihl and Husqvarna. I try to be as safe as I can, for myself and bystanders. I have great respect for trees, even after they are down they can hurt you. I will be careful.
Thanks for your concern,
Bill

Or how about running shoes and running as fast as ****!

I have different take on the issue. What you want to do has hidden dangers might not work as expected. Initially the tree will move in the direction of the force applied but when the rope gets slack the tree is free to fall sideway. So before you cut it make sure that the wind direction is right and the weight distribution of the tree will help you to drop it where you want it. If you tension it with your vehicle or tractor wind force in opposite direction might(unless the vehicle is really heavy) throw it like rag doll. Ask me how do I know it.

Ok,so how do you know and did insurance cover the damage? :ambulance:

Friend of mine was felling a tree and wanted it to fall in certain direction. They tied a rope high to the tree and tensioned it with an old 150 pickup. When they cut the tree it fell exactly in opposite direction being blow there by wind. The pickup was flying like a rag doll and was airborne quite a distance. Fortunately nobody got hurt and nothing was damaged. When the tree started going in wrong direction everyone was screaming "oh sh!!t" but when it was over everyone was laughing. Fortunately neither hospital or insurance were involved.
