    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…

Rated 5 out of 5 by This saw is great! I've owned several Stihl saws from a 034 Super AV down to a 180. When I sold the 034 I needed a lighter replacement, although I needed something that was large enough to handle firewood and clearing acreage for building. The Farm Boss lived up to the task. It's performed flawlessly. I've carried this saw for up to 6 hours at a time, felling, bucking and limbing. It is perfectly balanced and the antivibration is great, it's actually more comfortable than my little 180. October 24, 2016
Rated 5 out of 5 by Everything You'll Need in a Saw Purchased this saw from Hope Mills Saw and Mower after Hurricane Matthew for downed trees. This saw tackled a large (45') White Pine tree like it was a small scrub oak. I used this saw to limb the tree and to cut the tree into sections to load onto a front end loader. The saw never slowed down. It did everything I needed it to do and ran forever on a tank of gas.At the end of the day, I was completely satisfied with my purchase of this saw for all the above items, quality, dependability, power and value.I would recommend the Stihl MS 271 Farm Boss to anyone needing a chain saw.It's a good size saw that isn't too heavy by the end of the day and it provides all the power you need to cut.

Rated 3 out of 5 by Go Bigger!! If your looking to buy a chain saw like myself as a lifetime investment. Go Bigger!!This is a good saw for your average Joe/Homeowner!! But for some like myself thatlives in the rural area. This was my first purchase of a chain saw. Going on the advice of others was a Big Mistake!! Go ahead and spend the money and buy at least the commercial brand!! Go Bigger!! October 22, 2016
Rated 4 out of 5 by Great saw, would buy again It pulls a little harder than I thought it would, that's the only reason for not getting 5 stars. I like the saw and would buy it again.Now I just wish it would stay sharp longer. October 21, 2016
Rated 5 out of 5 by Love my new saw This saw is awesome, the power behind it is like no other saw I have had before. When cutting it's like cutting butter. I would recommend this saw to anyone October 21, 2016
Rated 1 out of 5 by Not worth a plugged nickel Purchased new from robertsdale stihl dealer, a lot of internal parts missing, used less than a week and have it in another stihl dealers shop, informed that it is either rebuild or parts have been taken off to put on other chainsaws, beware when purchasing the last one the dealer has ms271 has been good but this one Will not cut a two inch saplings. October 18, 2016
Rated 5 out of 5 by Owned a farm boss for 10 years I've had a farm boss for ten years now. It was my first chainsaw. Family has a 560 acre farm and we heat 2 houses with wood furnaces in each one. Every spring I cut approx 20 cords of firewood. The saw is what it should be. Quality made and there when you need it! Been in the shop once. One new sprocket & 2 new bars in ten years. Will even give my fathers 460 with 20" bar a run for its money just not as powerful. Went with the 18" bar and cut limbs to 24" logs. It's been dropped in the creek, pinched in a falling tree, dropped off the back of the side by side at 25 mph and works like new. Stihl should keep making quality products! Buy it and be done!

Rated 5 out of 5 by All the power I needed Purchased after having an older commercialGrade saw with a larger motor. It performsGreat, Starts great, very fuel efficient, andI have had no need for more power yet ,and seems just as durable, "Love it"! October 18, 2016
