    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 530.
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 Great all around saw. A great saw that does everything I need. It's a work horse and yet light weight. The sales associate spent 30 minutes with me assisting me on my selection and product overview of operation once I made my selection/purchase.

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 though...wow! 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.

Rated 4 out of 5 by from Dependable, quick starter! My Farm Boss is always ready to get the job done. I cut about 30 cords in the past year on my homestead and I've never had a problem with starts or breakdowns. Keep the chain sharp and the saw keeps cutting. Sometimes on harder woods or when the chain starts to dull the saw will bog down but for the majority of my cuts the saw performs smoothly and runs right through. If the job calls for larger trees or several hours of daily use I would recommend a professional model. For an hour or 2 a few times a week on typical firewood or to fell medium sized trees this saw will get the job done reliably. I would highly recommend this model or pretty much any Stihl chainsaw. Don't forget your safety gear!

Rated 5 out of 5 by from MS 271 Farm Boss gets the job done! My Stihl MS 271 Farm Boss is exactly what I needed for the work that I am doing. Very happy with its performance and dependability. The machine has a good balance of weight and is easy for me to use when I need to. I would recommend this to anyone who has to cut wood every year. Either way Stihl is a great company that makes great products.
