    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 600.
Rated 2 out of 5 by from Unimpressed! Power and quality not what I expected. I’ve ran this saw for about a year now. Overall experience... very unimpressed. I have 2 Poulands I purchased from Lowe’s that perform just as well for 1/2 the price. I also have a Husqvarna with similar specs as the Stihl but it significantly outperforms the Farm Boss and basically just cuts better. I’ve changed the bars on my other saws, but it was after many hours of operation, however I had to change the bar in the Farmboss after usuing only using a few times. Not sure the Oiler keeps up with the saw. Been like that from day one. I will not purchase another Stihl product. Way over priced, but they do have effective marketing.

Rated 5 out of 5 by from Survived a lot of work! I've had my Farm Boss for one year. I own a small 23 acre farm located on the side of a mountain (Blue Ridge Mountains). My lower half is pasture, but it borders dense woods. I use my chainsaw pretty consistently. (A massive, two-day windstorm with 70+ mph winds just took down 9 trees.) The Farm Boss starts every time and, frankly, I did not winterize it because I used it all winter. The only problem I've experienced is, what I believe, some warping of hard plastic pieced under my chain guard. I've experienced a problem with tightening the chain, starting the saw, and having to retighten it again within minutes. Absolutely could be operator error, though. I strongly recommend this chainsaw, but get the more aggressive chains, they cut wood like butter!

Rated 3 out of 5 by from "NOT" Easy Start Back in Oct. with a hurricane approaching Florida I decided to replace my worn out entry level chainsaw. After a lot of research I decided on the Stihl MS 271 FARM BOSS. After the storm I could not wait to use my new chainsaw. It said it had "easy start" starting. NOTHING could be further from the truth. I could not start this chainsaw. To make matters worse, there was no customer support. You see the electricity was out for days. The store I purchased it form was closed for days. And Stihls customer support is located in Florida, so they were not at work for days either. Many times a day I would read the manual and try to start the chainsaw. Finally after days of pulling my arm was so sore. I developed tendonitis that lasted for 4 months. So basically when I needed the saw the most, this Stihl saw just sat "STILL".A week later I took it back to the store and embarrassedly asked for someone to show me how to start the chainsaw. He started it and then proceeded to high rev the saw for several minutes. That was something that the manual warned against. Said it could damage the saw until it was broke in. When I questioned him on that he just laughed. I have owned the saw for about 5 months now and I would say its 50/50 on getting it started. Sometimes it starts with no problem. But half the time it still will not start. I keep thinking I will figure it out one day, at least I hope so.When it works it seems to work good.

Rated 5 out of 5 by from Strong saw for the money After about 1 year with this saw I can say that it is worth the money. Starts without any drama. I don't make money or heat my house with it, so I can't say I need anything bigger or more expensive. With the 20" bar it will cut every tree in my woods. Typically I've been running this as my felling saw and then clean up with my 193T. This saw could be a little lighter and it is better with my 18" bar. The vibration seems very low compared to the saws I was running back in the 90's on my parents farm. We had some storm cleanup in my neighborhood and my neighbor was out with his much bigger saw. I felt a little size envy until 30 min of cleanup with mine. Then I realized how much I don't want to lift those bigger saws.

Rated 5 out of 5 by from Replacement for an MS250 I needed a larger saw when my 15 year old MS 250 went down. I am totally satisfied with this saw. Would highly recommend.

Rated 4 out of 5 by from Early glitch Starts easy runs well, second time I used it the chain brake would not release the clutch. Next day worked fine, probably small glitch.

Rated 5 out of 5 by from Great all around saw, even for heavy use Purchased from Power Barn Bradford, NH to thin 12 wooded acres at a vacation house in NH: Ash, Birch, Oak, Maple, and Eastern Hemlock. 18” bar.Starts readily from -10° F and up. We use Stihl 2 stroke oil exclusively. Cut trees up to roughly 24”, limbed and cut into firewood length. Total of roughly two cords a year for four years. Compared to competing saws, weight about the same, more hp, larger fuel and chain oil capacity. Used it for hours per day and vibration is well controlled. Tried another brand chain but Stihl chains are the best available, cut faster and stay sharp longer. Easy chain adjustment. We purchased multiple chains and have them sharpened by the dealer.Terrific value and one saw for all around tasks, We purchased a second Stihl for home use.
