Our largest saw is one of the most powerful in the world. The primary applications for the 3120 XP® are extreme logging, portable saw mills, and stump work. This saw is designed to pull the chain on our longest bars - up to 6 ft.! Like all Husqvarna saws, the 3120 XP® has a superior power-to-weight ratio. Combine Smart Start® with LowVib® and other ergonomic features, this heavy-duty saw is both easy to start and operate.
