FS 111 R
This fuel-efficient, powerful trimmer handles tough jobs and meets emissions requirements.

Product Description

When you need more power to cut through your landscaping tasks, the STIHL FS 111 R trimmer has the extra muscle you’re looking for. Its low exhaust emission engine is powerful and provides 30% longer run times than the previous model. This professional trimmer features a three-step start procedure that saves users time, and a vertical pleated paper air filter for extended service intervals. It also features a rubberized loop handle, providing a comfortable grip of product for users to work with ease while cutting through thick and thin.

  • 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.
  • Upright Translucent Fuel Tank
    Allows operator to easily check fuel level before starting work. Upright position makes it easier to refill.

To reduce the risk of eye injury always wear proper eye protection. Always use the appropriate deflector for the type of cutting attachment, as explained in your instruction manual.

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.

Rated 5 out of 5 by from Has great power I have this product, and push it to it's limits. I mean I work this unit HARD! hill sides, and grass that's high... And i have to say, it's holding up. If there's any other out there that's has more power than this. I would buy it in a heart beat. I know it's heavy, and i knew this before buying it. So if your not a hard worker, don't think about buying it. It's for people that's hard worker

Rated 4 out of 5 by from nice but Probably would give it 5 stars except 1. it's a little heavy/bulky. 2. the line reloading process sucks, and the line that comes on it is about as tough as cooked spaghetti. 3. the guard that keeps cuttings from flying in your face does not do a very good job. I put some heavy duty line on it, and it works like a Cuban cane cutter with that on it:) It could be improved in areas of weight, spool and balance.

Rated 5 out of 5 by from Stihl For Life I’ve had other stihl trimmers this one has so much power and is just perfect if you have big weed jobs and is easy to maintain and start also it is very lightweight

Rated 5 out of 5 by from Powerful Trimmer I have had this trimmer for a little over a year. I can tell you without reservation that this will cut through weeds like a hot knife through butter. I use Stihl MotoMix as the fuel source and .105 string. It starts on the first pull every time. I highly recommend this trimmer.
