I see those rolly eyes and you are probbly right..I dont tend too last very long any more. In the last 2 weeks I have cut and burned 6 piles of brush and green briars. I got out about 3 times a day and work I dont last very long but do what I can. I am just so thankful for the battery powered tools I have. Sure a lot easier than trying too start a gas powered chain saw or weed eater.
