FS 131 R is rated 4.3 out of 5 by 6.
Rated 5 out of 5 by from A big step up for me, from typical low cost big store trimmers I'm near 70 years old, and wasn't sure I could physically swing a heavier "pro" trimmer like my new LS 131 R. (I've always purchased smaller, lighter, cheaper trimmers.) Big surprise when I first used this Stihl as, even at a few pounds heavier, it is so well balanced that I spent the first five minutes just hand holding it (with no shoulder strap) — but of course using the supplied strap is more comfortable in the long run. A real treat to me was how well the extra horsepower is put to use cutting my two acres+ of thick grass and weeds. Big surprise too at how well it cut the newer blackberry bush sprouts. (With the right head I think it will do OK on any part of a blackberry bush.) Add to that the overall quality (which I already knew about from my Stihl chainsaw) and it's well worth the cost for me, over weaker, lighter trimmers.

Rated 5 out of 5 by from this machine oozes unbelievable mega power what a machine it's unbelievable the power this thing has it almost makes 130R look like a joke just got it yesterday evening did a little testing did good and did some more testing in alot higher thicker weeds and only used 1/4 throttle and it went through it with ease no boggin down whatsoever im highly impressed and satisfied with this machine i also like the rubberised loop handle it's alot more comfortable than it is on the 130R the bigger fuel capacity is also a big selling point to me and is slightly lighter than the 130R but my one complaint is the short throttle trigger stihl should've kept the throttle trigger from the previous models on this one otherwise an outstanding machine worth every penny im gonna soon get the 36-2 head and put either .118 or .130 string in it and see what it can really do get this machine you wont regret it

Rated 1 out of 5 by from Great name, poor performance It's hard to start when cold. Unless you are running full throttle, it stalls out and boggs out. I am only trimming around my house and it's hard for it to run even doing that. I thought that I was buying a good quality item, I was mistaken!

Rated 5 out of 5 by from A Beast An exceptional upgrade from my FS130R. Powerful with much torque to get the job done efficiently and quickly, especially in grass, tough grass, weeds, and brush. A bit lighter than the 130R and a slightly largeer fuel tank as well.Starts quickly with little to no effort.Cannot ask for better trimmer than this one and I have owned a few like Echo (my second choice), Toro, Troy-Built and such...etc.

Rated 5 out of 5 by from Unleash the Beast!!! Really nice upgrades without price increase.Stihl super powerful and torquey. This one has a rev limiter on it to protect it but disappears when under load. Lot easier to work with or may I say simpler. Turn choke on - pull to start -hit throttle choke pops off automatically . Just push the button to stop. I use my fs90r for just about anything green stemmed, grass, weeds but when it gets tough I move up to the eliminators below:My FS130r was just to powerful it ate up orange .095 and burgundy line .105 in the 25 - 2 autocut so I strictly use it with Stihl's 3 blade brush knfe (mean combination) briars, inch trees, thick weeds.and vines. i bought the FS 131r to use with the new larger autocut 36-2 and the thicker .130 line. Well I have to say, this is a mean combination heavy weed and small woody weeds. Very little breakage and handle the power a lot better.The new Autocut 36-2 is made like the 25-2 but heavy duty and bigger. The buttons to release the top to get to the spool is a little easier to get to. I had to give the Fs131r a 5 for dependablity based on the performance of the fs130r. I will review this one again in the fall 2017 if there are any problems of dependability but right now she is a beast..
