    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…

Are You Ready for a STIHL?

MS 271 FARM BOSS® is rated 4.7 out of 5 by 685.
Rated 1 out of 5 by from I’d give mine a zero if possible I didn’t get much use out of this saw before the first repair needed to be made. After the repair was made it was used 3 maybe 4 times before it quit running all together. I have a saw with less than a dozen uses that is worthless. Because it is out of it’s warranty period, nothing can be done. My suggestion, run the heck out of your equipment when you purchase to find any flaws within it’s warranty.

Rated 4 out of 5 by from Great saw but it’s at the dealer right know it keeps cutting on a angle Great saw the dealer I bought it from needs more training they real don’t know much about the saw other than that they are great

Rated 3 out of 5 by from Difficult to start cold I have the 271 Farm Boss. I'll keep it because it is powerful and does a good job. But it is very, very hard to start the engine cold. The "Easy2start" system is not apparent even when brand new. I hear it is a gimmick. The saw floods easily. You may need to dry out the spark plug. You may have to remove the air filter to get it going. That helped me start it once. Just keep pulling and pulling. It will start eventually then work all day long...until the next day.So it is a good machine, but not the ultimate, yet expensive. I hear they can last for many years. So I'll stick with it. I just can't recommend it.

Rated 5 out of 5 by from its just big enough to do the big jobs. I have a couple of Stihl chain sews, but had a large lime fall off one of my tree(45'' in diameter), and needed a bigger sew this one worked out great. it took know time to cut it off the tree.

Rated 5 out of 5 by from Happy cutting! I would highly recommend this saw this is not the first Stihl saw that I own but this is my first brand new one. A family friend got me started in tree-cutting over eight seasons ago and uses nothing but, so that's what I've always known. I was tickled pink to get it out of the store up to the cabin and for the first time ever cut down more trees and had more wood than I've ever used before. It starts great handles great feels perfect it's everything that I've always thought I would own. I would consider thinking about the size of the jobs you need to take on and then gauge your new saw on the amount of work you're going to be throwing at it I am way happy with my purchase and I would highly recommend the Farm Boss 271 to anybody.

Rated 5 out of 5 by from Did not disappoint Saw cuts really well and starts great. Vibration is easy on the operator and the saw does well on the fuel. Well worth the investment.
Date published: 2018-08-06
Rated 5 out of 5 by from I seem to have more Stihl orange than I should but the Farm Boss seems to be my go to more often than not. This saw is the perfect balance of weight and power. Currently running a 20” bar, we have been cutting beetle kill spruce near Talkeetna, Alaska. 25 trees last weekend, bucking up about half. This saw has impressed me. I only reached for the 25”, 362 a couple times. When we are not in the spruce, we are doing birch for the cabin. This saw doesn’t slow down. Great product!!

Rated 5 out of 5 by from Step up and get done I thought I was happy with an older 14" Stihl - I was until I knew more about what I really needed. I'm a homeowner in Jersey. Plenty of aging Birch or downed trees. Sharp blades and all, it was still a chore with a small saw.But with the Farm Boss, it's game over. The right weight, tons of power and just runs and runs. I honestly think a more powerful saw is a safer saw. It's hard work to cut, move and dispose of all that stuff. If you're cutting faster, you're not as tired.If you use a chainsaw just a couple of times a year, this is still the saw to get. It will last forever and be up for whatever comes, (or falls) your way. Getting the job done faster and safer so I can go do what I really want to do.
