    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.

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…

MS 271 FARM BOSS® is rated 4.7 out of 5 by 404.
Rated 5 out of 5 by from This saw works great! I have owned/used other brands of chainsaws and so far this one is the best one I have owned.
Date published: 2017-04-21
Rated 5 out of 5 by from Best available for anything short of daily professional use Had it for a couple months. Already been through about 5 gallons of fuel and it is not a fuel hog at all. Just heavy use. Followed the instructions and have had no loosening of the chain to date. Taken down several large trees and made firewood for next year and then some.
Date published: 2017-04-20
Rated 5 out of 5 by from Starts right up and has plenty of power I have no problem getting this saw started even with a weak a weak right arm. Once started there isn't a job that it can't handle. It is light enough to trim branches and yet has plenty of power for trees as wide as the bar.
Date published: 2017-04-20
Rated 5 out of 5 by from Excellent I bought this as an upgrade for my MS180, man what a difference! This saw us easy to handle and has plenty of power!
Date published: 2017-04-19
Rated 4 out of 5 by from Great product for the money I love my new farm boss. The power is under rated. It will do all you ask of it and more. Only one problem was after only 4 starts the pull cord frayed out, but I noticed it before it broke. Took it back to the dealer and they replaced it in about 10 min. I believe it was a faulty cord and no reflection of the quality of the saw. I wouldn't trade my saw for anything.
Date published: 2017-04-19
Rated 5 out of 5 by from What you would expect from Stihl I purchased the MS271 Farm Boss with the 20" bar. I only have 1-1/2 hours on it so far, but I'm familiar with Stihl saws and trimmers. If you're looking for a saw that will do all of the work you ask of it, short of being a professional lumber jack, this is it. Plenty of power. You don't even have to go full throttle to get through most logs. The Stihl engineers build these things to work hard. I was pleased to see that after 1-1/2 hours straight of cutting, I still didn't need to adjust chain tension, or add fuel, or chain oil yet. Nice.
Date published: 2017-04-17
Rated 5 out of 5 by from Please don't with my purchase of this saw I am very pleased with this chainsaw I've had it two weeks and it's already payed for itself and then some
Date published: 2017-04-17
Rated 5 out of 5 by from Right tool for almost every job I bought this saw to cut up a bunch of hard wood logs I acquired and "hot knife through butter" is an understatement. As Stihl is known for very easy to start, manipulate and very little fatigue. I cut for two hours and then went looking for more things to trim up. Great workhorse saw.
