    Easiest starting trimmer ive ever owned
    The sales rep went over how to prime and start this trimmer in great detail. Also covered how to replace string in the head. I only use the stihl string, which works great for me with over a acre and a large pond in the back yard. Owned for over a year now, and this thing eats grass and weeds like butter, and i have no problems at all with the auto string head. Great product, as can be expected from STIHL, and as the saying goes, you get what you pay for and im so glad there is still a few great ... read more products still made in the good ole USA.

    big power in a small package
    I own a lawn maintenance company and bought this trimmer a few months ago. I have used trimmers from many brands but Stihl is the only one that I recommend. I love the power of my Stihl FS250 R, but I don't always need that much power and I just love the comfort and power that the FS94 has. And the 94 was ingenious when they moved the spark plug to the back instead of being so close to my arm...

    Look no further
    I worked golf course maintenance years ago running big stihl trimmers Now just take care of a few lawns and a few hours trimming weekly on my property. After replacing cheap straight shaft weed eaters every couple yr. Decided to spend the money and upgrade to real thing like my chainsaw and never made a better purchase this is the lightest most powerful well balanced trimmer with almost no vibration to hands. I'm so amazed that there is such a perfect trimmer

    Wonderful time saver
    Before purchasing, I was very skeptical about this product. After watching some videos of it in operation, I was certain that they had gone before and "pre-trimmed" the trees to make the trimmer cut faster for the video. I have other STIHL products and knew the quality would be good so I went for it. To say that we were impressed would be an understatement! This thing is a hoss and will save us a tremendous amount of time. We do not use it as a trimmer, but rather solely as a brushcutter for ... read more clearing fence lines and paths through the woods. It really does cut small trees quickly. Anything up to 1/2" it doesn't even blink, amazing. I've cut up to a 3" and you will have to cut on 2 sides but it sure beats running a chain saw bending over for several hundred yards of clearing fence! Another thing that I was worried about was backlash or kickback and warping the saw blade. We have used it for about 30 hours and this have not warped it yet and the kickback doesn't exist unless you cut on the side that is rotating towards you. I would recommend buying a 2nd blade so you can quickly change and keep working. Sharpen the used blade when it's dark out or you get back to the house. The machine is very well balanced and the backpack style (w/ shoulder straps) harness is a MUST. Zero fatigue after 4+ hours of continual use and none of that normal sense of relief to get the darn thing off like I have when I use my homelite weedeater. At first I wanted to go back and purchase a 2nd one but with all the time we are saving I don't think we could keep it busy.

    Stihl FS 310
    Purchased to cut brush on 20 acres. This product does the trick. I have cut 3 1/2 " trees with this cutter. Has alot of power. I am cutting brush, small saplings, briars,thick vines of 40 yrs on family farm. My father has stihl FS 90 v. The only negative thing is the bicycle handles. I think they are too wide. I guess that I should do a Youtube video on the cutter. I did alot of research before buying this stihl product. the sales rep at local stihl dealer recommended the fs- 250. I did not want ... read more to go to small of a cutter.

    Good power for woody material up to 3.5"
    Due to the fire danger of fuel build up, I bought a FS310 to clear the sagebrush from under the pine trees on 20 acres. For clearing brush, this machine beats a chainsaw due to three things; no more bending over, no more throwing chain, and only 22 teeth to sharpen! I was torn between the FS310 and the FS250. My dealer talked me into the FS310. This is my first 4 mix machine. I am very happy he steared me this direction. The machine has plenty of power and fuel efficiency. For clearing woody ... read more stems it is nice to have the big chassis and vibration system. It'll take out 3.5" stems in one hit. If I move to the other side of the stem, I can hit it again and take out 5-6" boles. At 4480' mine had a slight low end bog. At the 40 hour valve adjustment, the dealer adjusted the carb to take care of that. Now, it's broken in and just plain screams!

    I love STIHL equipment
    I just bought a FS110R i love this thing it has a noticeable improvement in power over the FS 90R. Stihl is by far a superior brand of outdoor power equipment over echo, shindaiwa, red max, etc. I would recommend Stihl to anyone these machines are lighter than competitors models and they are extremely well built machines. If you walk into a outdoor power equipment dealer and you dont see the Stihl brand you need to turn around and walk out. I own a variety of Stihl equipment and other than ... read more normal maintenance i have never had a problem out of my equipment.

    Great for the demanding homeowner
    Bought a smaller Stihl trimmer and was disappointed. Took it back and exchanged it for this one. It has the power to cut the heavy weeds and the grass around the trees. Starts like a champ. Nice and long so I don't have to bend down as much. I don't like the supplied line but that's easy to change.

    A very well built product.
    We use an FS 110 R for power sweeping in the Spring and Fall, and weed trimming (or weed whacking as us New Englanders call it) throughout the Summer. It's not the only Stihl product we own and use but it's the best one we've purchased and after many years of use, I'm most proud of it. Next Spring we will be purchasing another FS 110 R with other various attachments.

    Great Trimmer
    I looked at several different brands when my old trimmer died on me. After looking at dozens of models I pulled the trigger on the bike handle fs90. It has been nothing short of fantastic. It was more than I thought I would spend but you get what you pay for. It has plenty of power and it's lightweight. I highly recommend you upgrade to a double harness because the single factory strap leaves something to be desired. That's my only complaint is the strap. Great product STIHL.

    STIHL Trimmer
    I've been using STHL for the last 6 years and will never buy any other trimmer. It stands up to daily use and has very little maintenance. It always starts on the first two pulls. Even tho the price is a lot more than other models, It is worth the investment. Any home owner could use this product around the house for years, instead of buying a new cheaper model every year or so. And there are plenty of service stores to help with questions and repairs. I Use ACE Hardware for all my needs.

    Great Trimmer
    I purchased the FS90 after destroying several other trimmers, and burning up the shaft of my other Stihl trimmer. Am maintaining 4.3 acres in the country with heavy grass, weeds, and light brush. This includes trimming around a 1/4 acre pond. So far this trimmer has exceeded expectations. Vibration was low which was a nice surprise. Even more surprising was that I used less than one tank of fuel. With my other trimmers I used at least two tanks. It started easy and ran very quiet. The bicycle ... read more handle was easy to use and made quick work of the heavy grass and weeds.

    Love it!
    This is the best trimmer I've ever used. Been in the lawncare business for 15 years now and have used a lot of products. This trimmer beats them all by a long run. Some say the price is a little high but you get what you pay for. I definitely recommend it to anyone looking for a powerful, light weight trimmer that you can sling around real quick from a flat edge to a straight edge I don't even run it full throttle. I'd probably take off flying if I attempted that. Buy this trimmer and never look back.

    Lots of torque...
    Great trimmer, made the switch from running Husqvarna 326 line trimmers and couldn't be happier. Has enough torque to leave an edge that looks like it was cut with a blade. Inexperienced users beware, it has a lot of low end torque that will chew your edge up if you don't know what your doing. Can be a little hard starting on cold mornings. What tools don't have a starting ritual though? Overall I'm very satisfied with the purchase. When it comes time to swap out our pole hedgers they'll be 4Mix also.

    STIHL FS100
    The weight of the fs55 with the power of the 110! very lightweight and powerful the perfect trimmer for trimming around a big yard or all day use thanks to its minimal weight. If you want attachments or do super heavy field/brush clearing this is the wrong trimmer, but if you want a lightweight, reliable, powerful trimmer for large yard jobs this is perfect.

    Excellent trimmer, plenty of power
    This is by far the best trimmer I have ever used and I've used a lot of brands. Has plenty of power even for the thickest grass and brush. Definitely spend the little bit extra and get the fs130 over the others. I only paid an extra $30 for the fs130 over the fs110 and I'm glad, not that the fs110 is bad but it makes sense to pay the 30 bucks extra for the bigger engine and more power. Also glad I got the one with the bike handles it really saves my back.

    Great power easy starting
    I bought two of these trimmers to replace two of lesser quality that broke down this year. So far they both start on at least the second pull and usually the first. They are used heavily along a 20 + mile pedpath that is over grown with knot weed and other trash brush areas. No problems to date, the string feeds out and seldom jams like our old ones did on a regular basis. I would not hesitate to recommend these trimmers.

    Excellent machine for the price and performance
    The manual recommends running the FS130 at half throttle for the first 3 tanks of gas. At half throttle the machine chewed up weeds and vines that were growing on my fence line better than any other I have ever owned. Cleaning 25 acres of horse fence with the bike handle attachment and shoulder harness was almost fun!
