Yep. Conversing via typed words VS face to face leaves a lot to be desired. We cannot see the person's face and expressions. Some folks I know type with an accent, too.
Anyhow... no harm in respecting each other, right?
Now back to trees....
The last tree I took off of our property was about a 60' sycamore. It was leaning towards our house. I have about a 100' piece of thick steel cable from a tow truck winch. I climbed up the sycamore and pulled the cable up with a rope. Then I chained the cable to the tree about 40' up. Finally, I attached it to my old 4wd pickup truck. I made the wedge cut in the direction I wanted the tree to fall and put a lot of tension on the tree with the truck. Then I made my final cut and it fell as planned. I figured the tree was not that big and the worst I could have done was drop it left or right about 70 degrees from center, but the house was safe. The tree was small enough that the pickup could pull it down. A large tree could put enough pressure on the truck to drag the truck around easily. Sometimes it is best to drop all of the branches off of the tree straight down to the ground and then start taking off bits of the trunk from the top, down. However, this is best left to the pros with climbing gear and/or a cherry picker truck. We have to pick our battles as we go.
I once saw a program on T.V. where a guy had a large tree in his back yard, over some structure and there was no where to let anything fall. The tree climber went up and fixed a rope to the top of the tree, over the house, to a truck in the street. Then he would clip drop lines to the tight rope, tie the drop lines to branches, and as he cut off each branch, the branch would zip line down to the lawn next to the truck. Very cool. He almost the entire tree that way, until all he had left was about 25' fo trunk. Not sure what he did after that, but I think he just lowered each piece down to the ground from there.
