    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 704.
Rated 5 out of 5 by from Cuts like butter through 12" trunks... I bought the saw through an Ace hardware store just a block from my home. They set up the saw, filled it with premix fuel and filled the bar lube tank. I brought it home and ot would not start. I flooded it it turned out. You only need to fully choke this saw for two pulls and then reduce the choke to half. Today I cut a medium sized cedar tree (12", 40') that had fallen with relative ease. After learning how to choke it. it always starts without any issue. I am very pleased with Steelman's Ace hardware for having exceptional customer service supporting me after the sale making sure I was happy with my purchase.

Rated 5 out of 5 by from All the power you need, I bought the Farm Boss to use around the farm. I have a lot of trees that need to be felled and barns to repair/build. After using this on a few trees I have no doubt that it will do everything I need it to. It starts every time and I have confidence that is is going to start every time. I got the 20” bar which I thought was a little big when I first got it, but it should work great with a chainsaw mill. I made a swing set with the wood that I cut down. It is powerful enough to go through anything, but also versatile enough to use for finishing touches. I will Most likely get a smaller bar to go along with my 20”. Buy 1 saw that will last you for a long time or waste your money on the other brands that won’t. You get what you pay for.

Rated 5 out of 5 by from Stihl ms 271 I had one of the older pro series ms 260. I bought this as a back up becaise the 260 was getting older. So far this saw seems to run great and has great power.....considering it's homeowner grade compared to my old 260 pro. If this saw does half of what my 260 pro saw did.....i will be another very happy customer......i can't say enough about the older 260 pro. Best saw hands down I have ever owned....im excited to see what the new 271 has in store for me. Thank u stihl for making a quality, virtually maintenance free saw!!!!!

Rated 5 out of 5 by from The only saw left standing I bought this saw a few years ago and have cut over 50 cords of wood with it. Recently my neighbors and I cut down several large oak trees and after about 2 days of cutting all the other saws were burned up, broken or in need of serious repair. The only saw left running was the Farm Boss. No other chainsaw compares.

Rated 5 out of 5 by from 271 Farm Boss I had a 251 prior to buy the 271. No comparison the 251 was a good problem free chainsaw but the 271 is in a whole other league. Very pleased with this Chainsaw. Highly recommend it.
