    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 from MS271 FARM BOSS I've owned my farm boss for just over a year and it has performed great every time I've needed it. It is the perfect middle of the road saw to have for cutting firewood or just doing some branch removal on trees in the yard.

Rated 5 out of 5 by from Runs smooth, cuts well, and starts easily. I have owned other chainsaw and weed eater brands before. Non have operated so smoothly, started so easily, and cut so well.I have a forest preserve behind my house. It is an HOA owned property. Homeowners that border this forest preserve, are collectively pushing back the invasive species like honey suckle, grape vines, and deadfall. The deadfall is usually tangled in the honey suckle and grape vines. We are felling ash borer killed trees that have a trunk diameters up to 25 inches.The Farm Boss 271 is eating this stuff up!It is a joy to operate.markm

Rated 5 out of 5 by from My pull-starter arm will never be the same! I use a chain saw a few times a year...clearing new tress on our property, cutting firewood while camping, and getting some nice hickory logs for my BBQ smokers. For exercise, I've been staying in shape by yanking the pull starter on my old saw about 60 times every time I use it...then babying the choke for 10 minutes to keep it running. Well, I finally listened to friends and picked up a STIHL. Wow! It runs, it cuts, and it never argues with me! I should have done this a long time ago.

Rated 5 out of 5 by from Tackles much bigger trees than I thought. We live in the Northeast and there were multiple NorEasters this year bringing down several of the largest trees on our property. We had to cut up several trees that had 30+ inch trunks. This saw cut these large pines like butter. 4 hours of steady cutting without a hitch. Just fuel, bar oil and cut, cut, cut. Pro quality for the homeowner.

Rated 4 out of 5 by from Works great I bought mine last year, I have 40 acres in northern Wisconsin I have purchased 3 other saws. 1 I bought 15 years ago works good. The others bought in the last 2 years they are junk already. Decided to buy a better brand and I wish I would have done that years ago. Will continue to but Stihl products in the future.

Rated 4 out of 5 by from Great to finally have a quality saw I'm a homeowner that enjoys cutting and splitting firewood for my fireplace, backyard fire pit, and for camping trips. I've been using Craftsman saws my whole life, and at 48, it's great to finally have a quality saw. Starts right up every time, runs like a charm, and handles really well. I could use a little more horsepower, but it's not really a big deal. Love the saw.
Date published: 2018-03-23
Rated 5 out of 5 by from Perfect for what I use it for. I use my MS 271 to clear fallen trees and to cut firewood. Whenever a storm hits I keep it in my truck and use it as needed to clear trees from the roadways in my community. It is easy to start, not too heavy to use and it cuts well. Maintenance is easy. I recommend this saw.

Rated 5 out of 5 by from Buy It!! I have had this saw for about 2 years. It is an absolute beast and is one of the best tools I own. Do yourself a favor and buy one. Stihl is expensive, but as the saying goes...“When you buy quality, you only cry once!”
Date published: 2018-03-22
Rated 5 out of 5 by from Great saw!! I was debating on this one and one of the other popular name brand saws. So glad that I bought this one!! I bought mine for cutting wood for my personal use and I love it. Cuts very fast. I will not buy anything else. I waited for a few months and several uses before I posted my review. But you will not be sorry if you buy this saw. This may be a little big for just using it to cut wood for myself, but I love it.

Rated 2 out of 5 by from Warranty is garbage! I bought an MS 271 a little under a year ago. Used it very lightly only cutting small trees to clear part of my yard and to clean up fallen limbs from storms. One day it stopped working and overheated, melting part of the case, clutch springs, and brake bands. Service department charged me to fix it because they say that it happens when it is ran wide open with the brake engaged. Problem is, that didn't happen. The metal ring around the drive gear came apart and got stuck on the chain. I bought a Stihl for the warranty but it doesnt cover anything apparently. Not happy and I won't ever buy Stihl again.

Rated 5 out of 5 by from Great saw A good amount of power for the weight. The vibration absorption features are very nice. The tool free fluid caps save time as well. Perfect for small to medium firewood.

Rated 5 out of 5 by from Great saw This is the premier saw in the Farm and Ranch line. The Farm Boss is a workhorse as hundreds of reviewers will attest. I have run several of these and always found them to be reliable and powerful enough for most cutting jobs. If you are serious about a saw that will get a LOT of use, I urge you to look at the 261CM in the pro line. It’s got a better power to weight ratio and I have found the M tronic system to be very reliable. Again, the Farm Boss is a very good saw. But if you like this, for a bit more money you will REALLY like the 261CM.

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 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.
Date published: 2018-02-24
Rated 5 out of 5 by from This product is very reliable. I have many Stihl products and this chainsaw doesn't disappoint. It is easy to start, easy to refill both gas and bar chain oil reservoirs. The power and weight are perfect.

Rated 5 out of 5 by from Great saw for residential homeowner with wood stove. I purchased the saw because I had 16 face cord of logs delivered to get the wood cut and split for next year. My son and I decided this year we would do the work ourselves vs having it cut and split. The saw has worked great and in just a few weeks after work, we have gotten more than half of it done. The saw has started easy and runs smooth. Cuts through various hardwoods with ease. Would recommend this saw to regular wood burners!

Rated 4 out of 5 by from Bar run's dry / Have To Prime the engine to start The 271 run's great once it's running. BUT when the engine is cold { outside temp is in the 60s} I Have to prime the engine by taking the spark plug out and spray WD40 into the chamber to start it. But when it's running it's run's great and stay's running tell you shut it off. Lot's of power, fell's good in your hands and it's a dream working with it. But the chain run's to dry for my liking, I first noticed it after the first 5 min of using it. So I took it back to the dealer [ where I got it ]. And he said it's works just fine and I said this is not good. I still use it, and I like it a lot, but I wish it had a manual oiler, not a auto oiler. Sill on the first bar & chain after 16 cords so i guess it's ok. On that starting thing, When it's hot and run's out of gas and I fill the tank, with in the first 15 min it will start first pull.
