Tree Cutting tips....
I know its not an Evergreen, but a neighbor of mine up the street just killed himself, cutting the lower branches off an Oak tree in his yard. He would climb up a ladder, cut the big branches slowly with his chainsaw, just enough so they would 'bend' to the ground, but he wouldn't cut them all the way thru. Then he would go down the ladder, tie a chain to the branch, and pull it off the tree with his tractor.
Well, the last branch he did this to, went fine, until he started shackling the chain to it. It released from the tree by itsself while he was still chaining it up, and it fell on him before he could get out of the way. Nobody came around for 3 hours. Many family members drove by his tractor, but didn't stop to look for him
I think the mailman found him.
