Hi all, New guy here. I've owned my property for 10 years and have felled and cut firewood with my MS 310 with a 20" bar, and it has served me well. I have a few trees on the property in excess of 40" that I've been thinking of taking down. One in particular is a Black locust that is right next to the house. It needs to go because it has been infested with carpenter ants and I want to keep them away from the Hemlock siding. It also has 3 or 4 trunks splitting off the main trunk one of which is dying. I can't see the expense of buying a larger saw for a couple of trees but I think the 20" bar is too short. Has anyone ever run a 28" bar on this size saw for these size trees. I know the recommended bar is 20" and you could buy the saw with a 25" bar. I was considering using a skip tooth chain with a 28" bar. Appreciate your comments.
