FS 111

FS 111
A powerful bike-handle trimmer made for professional use, featuring simplified starting and 30% longer run time than the FS 110.

Product Description

Landscaping professionals that demand power in their mowing applications will love the STIHL FS 111 trimmer. With its low-emission, 31.4 cc engine, grass and tall, thick weeds don’t stand a chance. And because it features a larger fuel tank, the FS 111 delivers 30% longer run times when compared to the FS 110. Its bike-handle design also includes rubberized grips for enhanced comfort and leverage. The trimmer features one touch stop and a simplified starting procedure enabled by the semi-automatic choke lever. Add to that an improved air filtration and STIHL exclusive IntelliCarb™ technology for maximum RPM when air filter begins to clog. Need to cut down heavy brush or saplings? The solid steel drive shaft accepts a wide range of heavy-duty cutting heads, including metal blades.

Reviews

FS 111 is rated 4.2 out of 5 by 9.
Rated 2 out of 5 by from not the best I have used stihl products for years. This is my first disappointment. Trimmer has no power, looses power any time you get into thicker grass. Has wicked vibration. Now has a paper air filter which isn't goin to work in the Florida rains. Also has a new trigger which is going to break. Previously has the FS100rx, loved the product. This new model is not going to work for me.

Rated 1 out of 5 by from Poor Line System. Line Dispensing System Is Poor Design. Line Snaps Off Inside The Spool Every Time In Use. I'm Going Back To My Sears Craftsman Model. They Have A Threaded Line In Sections Which Takes Just Seconds To Load. Stihl System Fails Every Time And Loses Time On The Job.

Rated 5 out of 5 by from Product has amazing power I purchased the Stihl FS111 at the end of last summer for my house and my small lawn care business. The trimmer cost me nearly $500 after the oil i purchased with it to extend the warranty and i also purchased the 8 tooth grass blade for it too. The high price tag was a burden at first but as soon as i started to run it, it was well worth it. 1 hour jobs became 20 minute jobs. The trimmer starts within 3 pulls everytime of use, either cold, hot or anywhere between. Great unit and a good value for anyone. The only bad thing about the unit is its heavy weight. But its expected of something this heavy duty. I would definitely recommend it

Rated 5 out of 5 by from Outstanding product for the money. This is by far the best trimmer out there for the money. I have put this trimmer through things that other "comparable brands"have failed at. If you are looking for quality trimmer and don't want to spend a thousand dollars, look no further.

Rated 5 out of 5 by from Awesome Power This is an amazing machine!!! It has all the power one needs to get the job done. Buy the saw blade kit and save some time with honeysuckle bushes and saplings! This product doesn't disappoint!

Rated 5 out of 5 by from The best I bought this to use in the woods cutting small trees to widen trail and it cut so well I used it to make larger plots and shooting lanes. Works great in the yard doing my edge work also. One pull and it starts. This is my first Stihl and it has made me a believer. I am going to replace all my other "orange" equipement with Stihl's. A little expensive but well worth the cost of having quality equipment in your hands
