I have a small apple orchard of about twenty trees and have always trimmed them by climbing around and using a hand saw and loppers. I am now getting old enough that this is not as fun as it used to be and the trees are also getting bigger. I was thinking of getting a pole saw to help with some of the pruning. I also would be using it to prune shade trees in my yard and my twenty acres of woods that has suffered a lot of ice storm damage. It would get a moderate amount of work. I was wondering what would be a good one to buy? Sthil, Echo, or maybe a poulan with less reach and less weight but also much less money.
