  • Shoulder Strap / Carrying System
    Using a shoulder strap or carrying system helps distribute the weight of the equipment for increased operator comfort and improved maneuverability.
  • Multi-Function Control Handle
    Having easy access to all of the controls on one comfortable handle makes it easy to complete tasks so the operator’s hand never has to leave the handle.
  • IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor measures the air pressure on the clean side of the air filter and adjusts the metering diaphragm in the carburetor. This keeps the RPM at a consistent level, even when the air filter begins to clog.
  • Purge Pump Primer
    By pressing the bulb, this small fuel pump delivers fuel to the carburetor, reducing the number of starting pulls needed after an extended break between uses.
  • Anti-Vibration System
    STIHL has a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

FS 111 R is rated 4.6 out of 5 by 52.
Rated 5 out of 5 by from Excellent trimmer; powerful; dependable I bought this FS 111 R unit in August 2019 and it starts up great and I like the kill switch feature on the handle. It idles well and is light relative to the power it produces. It trims well and so far dependable.

Rated 5 out of 5 by from PLENTY OF POWER AND TEARS DOWN EVERYTHING I HAVE THROWN AT IT. I PROBABLY COULD HAVE GOT BY WITH LESS POWER BUT I ALWAYS LIKE TO HAVE EXTRA RATHER THAN WISH I HAD WENT BIGGER. IVE DEFINITELY BEEN PLEASED FOR HOW MUCH IVE USED IT AND THE WEEDS IVE POWERED THROUGH. HAS A GOOD PRICE IF YOU WANT SOMETHING DEPENDABLE AND BUILT FOR THE CHALLENGE. YOU GET WHAT YOU PAY FOR AND IM SATISFIED.

Rated 1 out of 5 by from This trimmer is terrible I'm the manager of a cemetery and we have had nothing but problems with these trimmers. I wouldn't recommend this trimmer, the upgrade from the 110 to this one is the worst that stihl has made!

Rated 5 out of 5 by from Very Powerful Trimmer Let me start by saying that I very rarely write product reviews. I am so pleased with this purchase that i felt obligated to write a review on this product. I recently bought a large property and knew that I would have to perform a variety of trimming tasks. My FS 111 R has been fantastic so far. One pull on choke, then one additional pull and it fires right up. One thing I have noticed is that it must be primed, as per the instructions, about five times, even if it has been running. This isn't a big deal to me. It is not a light machine, but it has ample power. I have used about 10 other trimmers in my life, but this is probably the last one i'll buy. I picked up the pruning saw attachment and the 145 degree hedge trimmer for this a few weeks after purchasing the trimmer, and this trimmer runs both of these attachments with gusto. I don't regret going this route instead of the Kombi system.

Rated 5 out of 5 by from Great trimmer- string feed still needs work Great Stihl product, powerful- starts 1st time every time, even after a winter hanging. String feed system is somewhat unreliable, but easy to fix when it goofs.

Rated 5 out of 5 by from Excellent product This trimmer is easy to start, light weight and will cut through just about anything.

Rated 4 out of 5 by from I like this product except the trigger i like the power an extended run time however the trigger is less then desirable for all day use. I have been landscaping for 20 plus years and this paddle trigger is very tiresome and only allows for one finger operation and if your finger gets sweaty it slips off . I wish the trigger was different is my only compliant. The weight is good and everything else but the trigger.

Rated 5 out of 5 by from Very reliable and powerful This machine replaced a 30 year old Stihl trimmer that was getting pretty tired. I love this new FS 111R. Very powerful and is very easy to start. I would buy another in a heartbeat.
