I don't have a chainsaw and really don't need one where I live in AZ however, in the early 2000's I was at a house in West Virginia installing a satellite dish and the customer had too many trees to get a line of sight. He told me to start putting up the dish and he'll take care of the trees. He emerged from his shed with about a six foot monster of a chain saw. Nothing you would find on any shelf at a chainsaw dealership. He proceeded to drop about a dozen trees it what seemed to be a couple of minutes and then another half dozen more to be sure he had a clear line of sight. Needless to say, his house was gonna stay warm that winter.
