The STIHL MS 391 is the ultimate farm saw. Extremely high torque makes this chainsaw more than able for any task on the farm. You wont be left wanting power with this chainsaw.

An easy saw to control and operate, with features such as the Decompression button which makes it very easy to pull the pull cord which would normally be difficult on a chainsaw of this size. Other features like a single control lever for choke and the on/off switch and the STIHL anti-vibration system make this saw a market leader.

The STIHL 2-MIX engine reduces fuel consumption by 20% and emissions by 50% on previous models. Another important feature is the new air filter system which drastically reduces the intake of sawdust for cooling the engine and means maintenance needed is also reduced.

STIHL engine technology means low fuel consumption, longer run times and reduced emissions in this high-powered chainsaw. The MS 391 features our newest engine technology that adds fuel efficiency while reducing emissions as compared to other models. Though equal in weight, the MS 391 is more powerful than the MS 311. Add to that an optimal power-to-weight ratio and you have a chainsaw that’s cut out for the big jobs in field, farm and ranch. Felling trees, cutting firewood and cleanup after the storm just got a whole lot easier with the rugged MS 391.
