I am in the market for a new chainsaw. What size would be the smallest I need. I was using my brothers old 40cc pioneer, but he took it back(he moved). Now I am stuck with a 36cc brush saw. The 40cc seemed a little small, but heavy. And it was tuned by a chain saw racer, so it was a little more powerful than most 40cc. Canadian Tire has pioneer 46cc, and a troy built 48cc. I mostly cut small stuff, for stove wood. I heat with wood, cutting up dead trees on my property, or cleaning up after the loggers.
