So far only used on one job, the 20” bar cut through 18” logs with ease with no strain on the engine. I only have this one experience to go on but I was impressed by its performance and totally satisfied with my purchase up to date, not too heavy and well balanced.

Bought this chainsaw on the recommendation of the sales dept at R&T and have not had a single issue with it in over 6 years of use. MS391 is an exceptional well made powerful chainsaw. I’ve moved up to a 20″ Guide Bar and it’s still got more than enough power for old oak and beech trunks. a great all-rounder.
