You might want to consider getting a good pole saw (I like Stihl). It really cuts down on the bending and stooping while holding a heavy chainsaw. It also lets you thin out brush without having to walk in amongst the poison ivy, snakes and biting insects.
The pole saw really comes into it's own when you're doing maintenance work on lanes with a lot of up and down to 'em. Instead of felling a whole tree to get rid of future drooping branches that obscure your targets, you can just lop 'em off quick and easy.
I have an electric pole saw that works well around the lot. I have a receptacle on the pole near the road and yesterday, used that and another regular electric chainsaws to cut small trees and branches to improve vision coming out of the driveway into the relatively fast traffic on the rural town road. (What (45 mph) speed limit?)
