    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.

MS 271 FARM BOSS® is rated 4.7 out of 5 by 358.
Rated 5 out of 5 by from Great saw I recently purchased a few acres and had to clean up some fallen trees. Spent too much money on cheap saws in the past. I was amazed with what it will do. I have pushed it hard on some large oaks and it hasnt let me down. I went with the 20 inch bar. Some have said they find it heavy, I dont feel that way at all. It is a great saw and I like buying from a dealer that stands behind it as well. The sales person made sure I was comfortable with it and was making the right choice. Easy to start and operate and is comfortable in my hands... i look forward to taking the chain off and scaring the heck out of the neighbor kids at halloween as well jumping out of the bushes.

Rated 5 out of 5 by from Awesome saw! This thing has all the power I needed to cut down some large pines. It cut like a dream! Only downside is it's a bit heavy. However, it has the power, and cuts wonderfully so I can't complain. It took a while to get it started intially, but after that it cranked up with no issues.

Rated 5 out of 5 by from You need this saw! I have 20 acres and three places to keep up in the country.i bought the farm boss today setup with 20". I went to the dealer and picked it up out of frustration from my 16" craftsman. I've had two craftsman and they were decent..or at least I thought so. This farm boss beast knocks out as much in 15 minutes as it took my old saw in an hour. I'm eager to see if the chains last as long as I'm told. My old saw I kept 5 blades going through a rotation of sharpening. After a couple hours at the most, those blades were toast. I only got to cut with my new farm boss a couple hours today but the chain seemed just as fast and sharp as when I started. It's heavy however the saw does the work unlike the cheap small ones so it still requires less effort even with its heavier weight. It's a touch expensive but you won't regret spending it if you've never ran one of these models. The heavy duty chain makes cutting much easier. I was dreading finishing up a bunch of trees at my rent house but now Im not worried about it.

Rated 5 out of 5 by from Best saw I have ever owned or used. I bought a 271 about a year ago. We have about 20 acres of heavily wooded land around our house. Most of my cuts are southern pine and live oak. I use the 271 for everything from 2" limbs to felling and bucking, switching between 16" and 20" bars. Goes through oak easily. Recently we had a 90' pine come down in the yard; at the base it was probably about 48". The 271 with a 20" bar went through it like butter. My only trouble has occurred when I have a short first use and then shut the saw down; it is a little cranky to start afterwards. I've learned to let it run at idle for a few minutes with the first start; this seems to solve the problem. Highly recommended. I will always buy Stihl from now on, in the highly unlikely event that I will ever need another saw.

Rated 4 out of 5 by from Light Weight -- Power is Great Nothing to complain about on this saw, coworkers rave about it after letting them use it.
Date published: 2017-02-17
Rated 5 out of 5 by from Value I have owned the farm boss for a few years now and all I can say is that it performs every time. By no means am I a professional, cutting a couple cords of firewood per year along with property cleanup.

Rated 5 out of 5 by from Great saw for its size! Just picked one of these up yesterday and put it thru its paces today 2/14/17.Wanted a bit smaller saw for the "light" work but this saw thinks it a "big boy".Was cutting white oak, a very dense hard wood, I had the dealer put a 16" bar and chain on this saw and it cuts great. Even when you bury the bar!. I have a MS311 for the heavy stuff but may sell it and pick up another 271!Great job Stihl! Another fine product!
