I finally was able to drop and cut up those four trees two ash and two elm. The one pic is my brand new out of the box 660. I put three tanks of gas through it yesterday. Ran like an animal, 2540 worked pulling a couple of those trees the last elm was on the side of a hill and was heavy. Just went over 100 hours as you can see so it's time for the big fluid and filter change out. It was a good day got a lot done.
