    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.
  • Zoom
    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.

    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.

Important Information
WARNING! The occurrence called “kickback” can cause serious or fatal injury. Always read the instruction manual carefully before using your saw. STIHL uses a green and yellow color-coding system to help you select a powerhead, bar and chain combination that complies with the kickback requirements of ANSI Standard B175.1 (gasoline-powered saws) and §30 of UL 1662/ ANSI Standard B175.1 (electric chainsaws). Ask your STIHL dealer about safe operating procedures and the advantages of the STIHL Quickstop® chain brake, STIHL Quickstop® Plus (Q) additional chain braking feature, STIHL reduced kickback bars and STIHL low-kickback saw chains.

STIHL recommends the use of green reduced kickback bars and green low kickback chains on all STIHL chainsaws.
* The actual listed guide bar length can vary from the effective cutting length based on which powerhead it is installed on.
Note: STIHL recommends use of fuel with no more than 10% Ethanol content. Using fuel with greater than 10% Ethanol content may cause damage to your equipment and may void your STIHL warranty. Learn More…

Rated 4.6 out of 5 by 158reviewers.
Rated 5 out of 5 by Perfect combo of weight and power I have owned a Stihl 291 for over 10 years now. It saw occasional use until this week. It sat for almost 2 years, and fired up on the second pull. I could have used a 20" bar but the 18" was sufficient, even for the large trees I had to cut, including a live oak. Never slowed down and never missed a beat. I have cut up around 5 whole trees of over 20" diameter at 6 feet of height and haven't even used a gallon of gas. October 19, 2016
Rated 5 out of 5 by The MS 291 is versatile, powerful, and hand ability is perfect. It is light enough to handle small and quick cuts as well as powerful enough to tackle your larger ones. Though I was unaware this saw was equipped with an anti-vibration system, it now explains the comfort and smoothness when making deep cuts during long duration's of use. October 19, 2016
Rated 5 out of 5 by curious........... I've read a few reviews about 1( poor oiling of the chain ) and 2( hard starting, hard to pull start) on the MS 291.( 1 ) I wonder If they are disassembling/maintaining and cleaning the groove in the bar and oiling port after heavy use? (2) are they setting the auto kickback when they try to start it ? My 4 yo MS291 has none of these issues. I also use a full chisel chain and wonder if the semi chisel chain clogs the bar up faster w the .325 bar/chain? October 18, 2016
Rated 5 out of 5 by Powerful and easy starting So far everything is great, time will tell on overall satisfaction. October 12, 2016
Rated 5 out of 5 by Great saw well rounded for farm work and doesn't wear on you after long term use . Fantastic saw that meets all the demands I have on the farm or at home. Reminds me of my Dads Stihl 046 he had when I was growing up. Great value on the saw and it has plenty of power as well as speed. I would highly recommend this saw to others. October 11, 2016
Rated 5 out of 5 by Great power to weight ratio Great machine, a step up from the MS290 in power. This is my 4th Stihl chainsaw and there is no other brand October 11, 2016
Rated 5 out of 5 by My need for a saw the day after Matthew was great. I am relieved that cleanup has gone well considering: trees broken, trees uprooted, and large branches scattered over my property. The price of the MS 291 took my breath, but as soon as I fired it up and began the cutting process; I was in complete agreement as to which saw I needed. The MS 291 is a little heavy, so read the manual and do not use when fatigued. Stress is a huge factor during an event such as Hurricane Matthew. Take breaks and don't over do it. Because as much as I wanted my yard back to normal, I could feel the effects of overworking my body taking it's toll. I will resume after I have had time to rest. October 10, 2016
Rated 5 out of 5 by My 4th Stihl - and Maybe the Best One I Have Owned I just about wore out an 024 Wood Boss and a 026 Pro cutting pulp wood and firewood over the past twenty years. I sold those and purchased a new MS 291 and set it up with a 16" bar and a .325 sprocket and chain and used it this past weekend to fell 25 trees that either were dead from Oak Wilt or to remediate the spread of the wilt any further. These trees ranged from 5" to 28" at the base and I was amazed at the torque the 291 had compared to my 026 Pro. I cut everything up except 6 saw logs and the saw was still sharp. Hats off to Stihl engineering! October 5, 2016
