MS-291 Chainsaw 20" Bar

2025 Stihl MS 291 18 in

With dependability and an anti-vibration system, this mid-range chainsaw's fuel-efficient engine increases run time between refuelings by 20% compared to the previous model.

The STIHL MS 291 is built to handle frequent use around the property, with the power and features to take on everything from cutting firewood to heavier tasks. Its advanced pre-separation air filtration system removes larger particles before they reach the air filter, helping extend filter life and keep maintenance to a minimum.

When you need to make an adjustment, the side-access chain tensioner makes it easier to adjust the chain with a bar wrench. The Master Control Lever™ keeps essential functions in one place, while bumper spikes help prevent pull-in and provide better control as you cut. Built with lightweight durability in mind, the MS 291 gives you the practical features you need to get through the job without making the saw more complicated than it needs to be.

Features May Include:

Anti-Vibration System

• STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

Bumper Spikes

• These spikes prevent pull-in and provide better control, making cutting easier.

High-Tech Polymer Housings

• Housings are lightweight, withstand greater impact, and are corrosion-resistant.

Made in America

• A majority of STIHL products sold in America are made in America of U.S. and global materials.

Master Control Lever™

• The Master Control Lever™ is an easy to use single lever, operating the choke, starting throttle lock, and on-off switch. The operator must pull the throttle trigger before moving the Master Control Lever™ to the choke position.

Powerful, Yet Lightweight

• Built for lightweight durability and packed with features, this powerful chainsaw is ideal for frequent use and tasks around the home.

Pre-Separation Air Filtration System

• This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.

Side-Access Chain Tensioner

• The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.

Throttle Trigger Lockout

• This safety feature must be depressed before the trigger can be activated.

Toolless Fuel and Oil Caps with Retainers

• Simply lift the lever and twist the caps to remove or tighten. There’s no need to use a tool to tighten or loosen.
