    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.

MS 271 FARM BOSS® is rated 4.7 out of 5 by 591.
Rated 5 out of 5 by from Easy to start and easy to continue starting after stopping I bought this Farm Boss in Avalon Ace hardware in Orlando, FL. The instruction to start/operate at Ace was excellent and the product is fantastic, reliable quality. It has power and very easy to start again after putting it down after several minutes. Delighted with this new machine.

Rated 5 out of 5 by from Would buy again The only issues I have had were on the first tank of gas it took several pulls to start. On about the 8th tank of gas, the saw is well broken in, and starts like a champ easily every time. I have not owned a chain saw in almost 30 years of living in the city, but when I bought my ranch, I did research and settled on the Stihl 271 with a 20 inch bar. I am very happy for the purchase, and I know that this saw is going to last. I mainly cut central Texas yaupon and post oak, and while I may not be pushing the saw too much, I have had to cut a couple larger oaks. I regularly use the saw in very hot and dry conditions and have had no spark issues. The weight is fine for the size of the saw, and really after a while it's a reasonable weight for the size of the saw

Rated 5 out of 5 by from Starts easily and has plenty of power Took me two or three try's to master how to start this saw, but now it is a joy. Found this saw to cut much better than my 35 year old stihl.
Date published: 2017-11-03
Rated 4 out of 5 by from Nearly everything I expected This saw is nearly everything I expected from Stihl. It replaces a 35 year old Stihl 032AV. I am please with it's easy starting, and good power for the 18 in. bar and chain. The "locking" bar oil and gas caps take some getting used toThe only concern that I have encountered is that one of the bar nuts loosened and fell completely off the second time I used the saw - even after I had tightened those nuts before starting to cut.
Date published: 2017-11-02
Rated 5 out of 5 by from I would recommend this saw I wouldn't trade my new ms -271 for anything I was using a husqvarna 350 ,and a husqvarna 445 to cut with . I've sold the 350 and the 445 is now my back up saw. I cut firewood every day so I really work my saws and my new ms- 271 makes my life a little easier it is quick to refill with gas and oil and makes short work of white oak
Date published: 2017-11-01
Rated 5 out of 5 by from Fantastic saw for average use Has been finicky at first but is getting better every time I use it. Quite a difference between cold/hot idle so took a while to get adjusted. I use it mostly for firewood and it seems to do great on soft wood or even hard wood under ~16", but keeping chain sharp and not being aggressive is a must for larger cuts. Overall I'm happy with the purchase, but still think I would like a bigger saw, as I don't believe this saw would handle (power) a bar larger than 20".

Rated 5 out of 5 by from Excellent Chainsaw! I bought this chainsaw instead of hiring a contractor to remove a 100 foot fallen red oak after hurricane Irma. I have done all the work myself with just this chainsaw and a splitting axe. The saw has been extremely reliable and I’m sawing through the large logs with no problem. I had zero experience with a chainsaw and was nervous to do this, but it has been very easy! I did buy the protective chaps and watched the STIHL safety videos to be safe and found them very helpful. I have sawed for several hours at a time with it and never feel any fatigue as there is very little vibration. I’m very glad I spent extra to get this vs going with a cheap chainsaw!

Rated 5 out of 5 by from Performed as advertised. Powerfully, easy to start, smooth clean cuts. This is my first Stihl. No comparison to the Homelites and Craftsman saws I had purchased prior. A few extra dollars is well spent.

Rated 5 out of 5 by from Newbie Heaven New to chainsaws, but tried out my friend's 290, which he loves. Decided on the 271 for the sweet-spot between the lower-powered of the 251 and the higher power of the 291. 20" bar zips through the large logs on my new property. Used multiple times now without any problems - followed the instructions on starting and it's reliable and powerful every time so far.

Rated 5 out of 5 by from Plenty of power We live in a national forest that's been devastated by the Bark Beetle. We lost six huge pines on our property, so I bought the Farm Boss to buck them up for next year's wood supply. It cut like a knife through warm butter. Started up every time, and handled very easily. Even on deep cuts I never had a problem. Well worth the investment.

Rated 5 out of 5 by from The weight is very well balanced. Overall it is excellent. The only way I could see it being better is a larger gas and oil tank.

Rated 5 out of 5 by from Awesome performance extremely dependable I had 2 other saws over the last 20 years but this saw is the boss. I love it and wonder why it took me so long to buy the last saw I will ever need. Power dependability and quality are unquestionably top notch. Since I value my time and don't want to waste it fiddling with a poor saw, the value is also excellent.

Rated 1 out of 5 by from Disappointed in Ohio This is the 2nd Stihl chain saw I have purchased. I had to buy this one because the one I purchased last year didn't hold up very well. The chain kept coming loose and within a few times tightening it, the screw completely broke off and had to be replaced and now it won't start. This farm boss I purchased is worse. I used it within 2 days of purchase, the chain was completely dull and needed replaced and again kept coming loose and needed to be tightened after every cut. It also continually shuts off the minute I take my finger off the trigger. I doubt this is a problem with Stihl, especially after being sold a brand new chain saw with a completely dull blade, this I put on Rural King, but I don't exactly know where to lay the blame with the fact that one, 2 days after purchase won't keep running, and the other, after 2 days of use won't start and the chain tightening screw completely sheered off, I think the blame has to go to Stihl on that one. So now I have to find time and waste the gas to take them both back to the store to be fixed. I think they should have to come to my house to fix them since I used both a total of 4 or 5 times, and the newest one only once. Very disappointed. Oh and my mother owns about 5 Stihl chainsaws, yes 5, because she would have to buy another one to use whenever the 1st ones were in the shop being fixed, and not returned for months at a time, oh she didn't take them to or buy them from Rural King. And I don't remember the model #s off hand of either saw I purchased, but they are both farm bosses.

Rated 5 out of 5 by from WOW what a work horse!!! I purchased the MS271 Farm Boss about a year ago. It's the best chainsaw I have ever owned. This thing cuts like no other. I mainly bought it for the power to cut through Hedge and Locust trees, which are in abundance here in Missouri. This thing eats though these hard wood trees like a snack. So long as you keep the chain sharpened. But I have since moved to a place where there is only White Oak and cedar trees. I have cut about 8 cords of wood out of the Oak in less then 2 weeks and the chain hasn't dulled yet. The power it has is stihl going strong. I am now looking at purchasing another Stihl. Either the MS R C-M 362 or the MS 441 C-M Magnum for milling some of the logs I have set aside for making planks and what ever else I want to make. I have used the 271 for splitting a few logs down the middle and it worked great. Its just a little tougher on the chain. Tough choice to make on the next buy.

Rated 4 out of 5 by from Good overall saw I have had this saw for almost 1 year. Initially, I had some problems with the bar oil running out quickly and for some reason it seemed to be the 1st 3 or 4 times I ran it. Now, the oil usage is more reasonable. The bar and chain adjustment is simple/not complicated and better than the auto adjuster on my Dad's Stihl. I do recommend this saw for most homeowners. My only regret is that I did not buy a professional grade saw with a larger bar. I initially thought this saw would be big & powerful enough, but it has struggled bucking a larger river birch. It has been ok on oak and pine. I have another 2 acres of larger trees and will likely buy a larger saw. Note, buy the Stihl 2 in 1 filing guide chain sharpener. It works really well and is worth the money.

Rated 5 out of 5 by from Cuts like a hott knife through butter! Excellent piece of equipment. Quality built and should last a life time. Saw starts easy and performs flawless. Has sufficient power to perform above its class. I really like the new twist off fuel and bar oil caps. Do not hesitate on spending the money on Stihl products. If maintained properly you will be money ahead in the long run with Stihl lasting a lifetime.

Rated 5 out of 5 by from All the chainsaw that you'll need The Farm Boss did a great job after Hurricane Matthew in cutting large downed trees. Worked long hours and performed without any problems. Runs a long time on a tank of fuel. I couldn't be happier with any other saw. Hope Mills Saw and Mower was fantastic from the moment I walked into the shop and beyond after leaving with my new saw. They asked me what I planned to cut with a chainsaw, the amount of time I planned to be using the saw. They showed me several options based upon my needs and recommended the MS 271 Farm Boss. They reviewed everything concerning the operations and maintenance for the saw, as well as, accessories I may need from fuel, bar oil and other needs, instead of letting me leave without all the tools I would need why operating this saw.I was so impressed by their service that I've since gone back and purchased a small chainsaw for trimming/cutting limbs.

Rated 5 out of 5 by from Best chainsaw i've ever owned I have lived in Northern Michigan for 26 years. Moved finally to all wood heat. Needed a saw that was easy to start, handled easy, had power to cut through 2 foot thick oak and maple, didnt kill me on gas, was dependable and cost effective. Went to my local Stihl dealer McLeans ACE Hardware..and the MS 271 farm boss was recommended to me. Now i have owned Craftsman, Poulon, Mchulha, Homelite, and Echo saws over the years. None lasted all were a disappointment. The Stihl 271! Best saw i ever owned! Power, dependable, efficient, easy, cut 50 cord like butter! Thank you Stihl and thank you McLeans for convincing me to buy my first Stihl product.
