Back OT. I had to winch a few trees for a friend of mine one. His property was on a 30' rocky hill overlooking a lake, with the edge of the yard at the top of the hill and the trees towards the bottom. When he cut the trees they'd fall down into the water. From there we'd cut them into about 10 foot sections and winched them up the hill no problem. Make sure you use a properly rated chain, shackles, etc. around the tree and not a strap. The strap could get ruined by dragging it over the ground...this is one place where a chain should be used.
