Are You Ready for a STIHL?

FS 311 is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Best trimmer I have owned This trimmer is the easiest to start of the several I have owned over the years. This is the first Stihl trimmer I have owned, but I already own a chain saw and mini tiller made by Stihl. All of the products have been first class. For the first time, I have tried their pre mixed gas, oil, fuel stabilizer product to fuel it, and the difference in performance is phenomenal. The other great advantage is there is no strong burning oil smell usually associated with 2 stroke engines. The last one I bought was a 4 stroke made by a different company, and that was a huge mistake. It was hard to start, had little torque compared to this one, and it blew a head gasket early in the second year. I have learned my lesson, and will be sticking to Stihl products from here on out.

Rated 5 out of 5 by from Thoothpick Maker This is a review for the FS311 which is the made in America version of the FS310 all you have to do is ask your dealer for the FS311 to get the one made in America which is what I did. The trimmer is everything and more I had to order mine which took a week but boy was it worth the wait. The trimmer starts with ease and has power to turn a 300mm brush cutter blade, it comes with a three point shoulder harness that really saves the back it is balanced great with little to know vibration, coming from a standard weed eater let me tell you you will need eye and a separate face protector as this thing throws stuff at nearly light speed and will do some damage to those tender areas of your body, long paints, boots, eye and face protection are a must because if its exposed it better be tough. Keep people, animals more than 100' away at all times. This machine is great and gets the job done.
