A high-performance, high-tech, fuel-efficient chainsaw.

Product Description

The MS 271 FARM BOSS® replaces the mighty MS 270 with a saw that’s loaded with features and technology. It starts with a highly efficient engine that delivers 20% longer run times between refuelings – while cutting exhaust emissions in half compared to the MS 270. There’s also a pre-separation air filtration system that’s so effective, your air filter can last up to five times longer (now that’s high performance). All engineered into one compact, ergonomic design.

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.

    More information

  • 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.

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.

Reviews

MS 271 FARM BOSS® is rated 4.7 out of 5 by 948.
Rated 5 out of 5 by from Dominates the wood! I’ve whacked down oak, aspen, ponderosa pine, pinyon pine and juniper with the farm boss. It’s always started after a few pulls on choke & is ready to rip. Even on the bigger diameter logs I’ve cut through, it’s always had plenty of power

Rated 1 out of 5 by from Extremely Difficult to Start Does fine once it runs. It is just a matter of pulling until you are worn out.Get in a confined area and you are dead in the water.

Rated 5 out of 5 by from Good saw, better price. Best bang for your buck! Wonderful saw, bogs down occasionally on large dry and hard timbers, but by letting up pressure it will cut right through. I primarily use this saw for bucking firewood, and I have only good things to say. It always starts within 5 pulls (even during frigid days) and hardly ever stalls at idle (once warmed up). Highly recommend to do light felling, and bucking. Absolute workhorse!

Rated 5 out of 5 by from Great saw This saw is great. Tough, easy to operate, and has good power.

Rated 5 out of 5 by from Great Service This product probably has more power than what I will ever need. I never used a chain saw before prior to this one. So I have nothing to compare it too. The errors I have encountered have probably been to lack of knowledge on how to properly cut or use the saw. I've had a few issue with the chain and the saw actually working, but again I believe it has been user error, and not product malfunction.

Rated 1 out of 5 by from First and last time Stihl purchase We heat with wood so I don't buy disposables. I've always had 2 chainsaws on hand, one larger and another a more medium sized. My smaller finally bit the dust so I thought I'd try a Stihl because people who like them seem to really like them. The MS 271 seemed to fit the bill. I've had issues starting it from the get go, sometimes flooding or othertimes I'd get it started but it would only run if I kept my finger on the throttle. Then the muffler came off and wouldn't stay on from then on. Tried locktite but still wouldn't stay on. Took it back to the dealer for the muffler problem and the issues I was having keeping it running because I couldn't adjust the carb myself; Stihl apparently now requires a special tool they don't sell to the public to adjust the carb. The muffler problem was fixed but not the issue I have keeping it running. This saw was only in its second season of use and I've had more problems with it than my other saw that I've had for somewhere around 20 years. Got rid of it, took a pretty big hit, but live and learn. I thought I was safe giving Stihl a try; maybe I just got a lemon but I'm not buying another.

Rated 5 out of 5 by from Engine has enough power to drive the 20” chain without bogging. I own 4 Stihl chainsaws and this one is best by far. Not intended for light duty since the machine is not lightweight. Best used at waist level or lower.
