Model Features

  • Reduced-Emission Engine Technology - Caring for Nature
    The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.

  • Built in the USA
    Indicates products that are built in the United States from domestic and foreign parts and components.

    More information

  • 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.

    More information

  • 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.
  • 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…

WARNING! Improper use of any power tool may cause serious or fatal injury. Read, understand and follow carefully the operating and safety instructions in your instruction manual before using such products.

MS 271 FARM BOSS® is rated 4.7 out of 5 by 326.
Rated 5 out of 5 by from Great saw for the price Easy to use and great for cutting firewood. The True Value Store where I purchased the saw was great to deal with.

Rated 3 out of 5 by from wait and see I have had this saw for a bit over 1 week used it twice and it is harder to start, seems the flywheel has a habit of sticking which makes it stop in the middle of a pull which is very nasty on the arms to say the least. Will return to dealer to see what the problem is, I own 2 other Stihl saws as well as the combo and none have this issue. I feel it will be corrected

Rated 5 out of 5 by from Incredible saw While I was researching different types of saws to purchase, I came to the conclusion that anything other than a top brand would be a waste of money. So I went all out and bought the STIHL ms 271 farm boss and I could not be happier with the saw. It's easy to maintain, easy to use, and easy on the eyes. I clean it after every use and only use stihl oil and stihl chain lubricant. I don't see why this saw won't last me the rest of my life (29). Love it!

Rated 4 out of 5 by from This product was as good as the salesman said So far, I have been happy with the new saw. I purchased it with a 20" bar. It works great on smaller limbs. I think the 20" bar may be too much for this size saw. I will probably buy a 18" bar later once I get thru this large tree.

Rated 5 out of 5 by from Reliable and hearty when you need to cut a lot of wood Bought this for a small ranch and I can't rave enough about it. It starts every time, is consistent in its cutting, and is easy to clean and maintenance. Like with every chainsaw, avoid ethonal gasoline and fill your chain oil and I don't see why this chainsaw wouldn't last a life time.I've used other brands and was thoroughly disappointed. I decided to go for what I had heard was the best brand out there and I've never looked back.
