    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.

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 669.
Rated 1 out of 5 by from Not what it used to be. I purchased this saw based on the quality and durability of one that I previously use for many years. To say the least this one is a serious disappointment. I purchased it at Rural King and it stopped running during the first use so I took it back they would not refund it and would only repair it under warranty. Their repair only lasted until the next use when it failed within twenty minutes of use. I called Rural King and they required me to make a second round trip of fifty miles and this time I had to leave it requiring a another fifty mile round trip to pick it up.. I now have invested almost thirty dollars in travel expenses for as saw that has not even run for two hours.

Rated 4 out of 5 by from Real time saver Great saw, made short work of all the trees to cut. Not as good as a Light Saber for cutting trees but a close second. That's why I only gave 4 stars. Will have no problem recommending it to others or buying another.
Date published: 2018-06-11
Rated 5 out of 5 by from Cut down 20 trees so far no problem! I had problems starting one time but was because I flooded it. I followed the instructions to pull and dry the plug and pull the rope several times to clear the chamber and it fired right up. I love it!

Rated 5 out of 5 by from Great saw This saw is the perfect fit for all of my needs. Even with multiple full days of use it keeps going and fires right up when needed. Even at the limitation of the bar it wants to keep going. Great product and I would recommend to anyone.

Rated 5 out of 5 by from I have had this saw for 6 yrs. now,,,, with no issues. Like I said I have had this saw for 6 yrs. I use it quite often, as I burn wood to heat my house in the winter. I cut 3 months out of the year on a weekly basis, never had a problem with starting, breakdowns or faulty components. I will not buy another brand of any lawn tool or saw .

Rated 5 out of 5 by from Awesome saw, best one I have ever owned! This is an excellent saw for the money, I wish I would have bought it 10 years ago instead of wasting my money on cheaper saws. This thing starts super easy and rips though wood like you wouldn't believe. I have cut several truck loads of wood with the saw already and have had no issues.
Date published: 2018-06-07
Rated 5 out of 5 by from First Time Out First time out cut about a half a cord of oak. Plenty of power and cutting ability. A little issue with low idle, engine died a few times, took a little longer than would like to re-start, maybe due to first run cycle. Once warmed up no problems.
Date published: 2018-06-06
Rated 5 out of 5 by from Cuts great everytime Bought 5.3 acres and was using the M171. Decided to move up to a larger saw to make cutting even easier on the larger trees and this saw does not disappoint. .

Rated 5 out of 5 by from More powerful and better than ms 250 I’ve gone through a few of the 250’s. So I decided to get the ms271 and so far I have not been let down. It’s a lot more powerful and sure makes it’s easier cutting down the bigger trees on our property. I should have gotten this one years ago.

Rated 5 out of 5 by from one word: awesome my farm boss can handle any task. it powered through several cords of wood with no problem. able to tackle some big trees with it. starts on first or second pull every time Most dependable tool I own. Get one!!

Rated 5 out of 5 by from Keeps on running After frustration with a cheaper saw from a big box dealer, I purchased a Farm Boss. I'm cutting a large number of hemlock trees into firewood. After about 1.5 cords, I'm very happy with the Farm Boss. Starts easy, cuts even thick wet pieces with ease, and only stops when it's out of gas. It's a little heavier than my old saw, but the power more than makes up for the weight. Also, very little vibration for a chain saw. I enjoy the quick lock fuel and bar oil caps.
Date published: 2018-05-24
Rated 5 out of 5 by from Once tuned properly, it's a excellent saw. I bought the saw and it didn't run very well out of the box. I took it home and turned the idle up, leaned out the low and fattened up the high and now it runs like top. Very good power for a 50cc engine. STIHL saws are on the expensive side compared to other brands but you get what you pay for. This is my 3rd Stihl and will not be my last.
Date published: 2018-05-23
Rated 5 out of 5 by from Great saw! Great value! The model 271 is, in my opinion, one of the best values in the entire Stihl line, and all of their saws are great. What makes the 271 stand out is its ability to accomplish almost every job you’ll need it for. I have felled 14” dbh conifers with it and bucked up cords of oak firewood. Best saw for the price anywhere.

Rated 5 out of 5 by from Great saw for the price. Saw has plenty of power to cut any of the trees I have around my place . Seems to be lighter then my old 029 , which makes it easy to use for longer periods of time . A very good saw for anyone .
Date published: 2018-05-17
Rated 5 out of 5 by from Great saw!!! Cut about 3 cords so far and I’ve only filled it 3 maybe 4 times.. pretty efficient for a 50cc, fairly light for a medium/heavy duty saw, but heavy enough to cut thru thicker trees and hardwoods. I’ve cut mostly alder, madrone and fir and this thing has not let me down once. All my friends are jealous ... Oils the bar very well and also does not leak like the MS211 I actually bought and traded in for the farm boss knowing I like cutting bigger rounds.

Rated 5 out of 5 by from This product is great I like very much, had some wind storms over the winter which took some trees down cut them all up one Saturday. cut through those trees with no problem. started every time you pulled the cord.

Rated 5 out of 5 by from awesome saw I just purchased this saw and used it to take down a 20 to 30 year old willow tree. This saw had no issues cutting through the 30 inch diameter trunk and thick branches. very little vibration.

Rated 4 out of 5 by from Tough as Nails I have been clearing brush from a farm for approximately 5 years with this chain saw. During that time it has been dropped, run over, cut (with FS-130 brush cutter) and it still starts up in most all conditions. I just wish they would invent a chain that was as indestructible. Good Saw!

Rated 5 out of 5 by from Great product This thing is a beast, it will do anything you need. The power is all you will need, I have the 20 inch bar and the power is great, cuts thru anything like warm butter

Rated 5 out of 5 by from This thing rips! Needed a new saw to tackle some bigger wood this past weekend so I bought the MS 271 Farm Boss - I am very pleased with the saw's power/weight ratio, the smoothness (very minimal vibration), and the fuel efficiency of this thing is incredible compared to my other saws. Great piece of equipment!
Date published: 2018-05-07
Rated 5 out of 5 by from Should be called the Farm Beast..! This is a great saw. Good Power Starts up the same way every time. Its a beast and it chews up the wood. Great for dropping trees and cutting them into movable pieces. For those out there researching. This is NOT a trimming or liming saw. It is heavy and tiring to use as a quick cut. That's why I bought the MS 170 Yesterday for trimming and branching. You will not be disappointed with this saw. If you read bad reviews on this saw that is because of the user not the product. Key points to chainsaws. "Starting Memory" + sharp chain = Awesome saw! The only cons are. Its heavy (yeah it is its a beast) and for the money it should come with a full case not just a bar cover.
Date published: 2018-05-07
Rated 4 out of 5 by from Well Worth the Xtra $$ Starts easily. Restarts easily. Holds an idle and goes right back to work. I've worn out many chains (dealer resharpened 3-4 times each) and replaced 1 sprocket in 4 years with 2 major hurricanes on a small farm. Still runs like a champ ( I use Stihl chains and oil, and non-ethanol fuel). I marked the "Quality" down one mark because I think the 'high wear' parts could be a little more robust (they are quite pricey).
Date published: 2018-05-02
Rated 5 out of 5 by from Exceeds expectations I needed a new quality saw and didn’t look any further than Stihl. They have always been the gold standard when it comes to chainsaws. I bought my MS271 recently and took it out for some work around the farm. It starts up within 3 pulls and the it is fuel efficient for its size. I love how it cuts through wood with ease. In my mind It has already paid for itself.
Date published: 2018-05-01
Rated 5 out of 5 by from Great Saw I have owned several Stihl products and I have never had any issues with any. I love that all parts are made by Stihl and not by a third party like some other saws.This is my third saw and I loved every one of them.
Date published: 2018-04-30
Rated 5 out of 5 by from The 271 Farm Boss is another quality chainsaw by Sthil I live on a wooded 3 acres lot and have been using the the Stihl 290 Farm Boss for the past couple of years and after my son recently purchased his home on a heavily wooded 2+ acres I decided to get a second Stihl so we could help one another. Based on my local longtime Stihl Dealer's recommendations, I purchased the 271 Farm Boss. I wanted a saw with comparable power to the 290, but one with slightly lower compression to hopefully make pull cranking somewhat easier for starting (no, I did not want the Easy Start Option even though I'm in my 70's!). After having used the 271 multiple times I can definitely say it was the right choice. It always starts after only 2 or 3 pulls (and it is easier to pull than the 290!) and cuts through 20"+ Oak trees without any strain or hesitation. Another great saw!
