Rated 5 out of 5 by from This machine is a horse I bought this machine to nock down tall heavy weeds in a hurry and it does this job perfect. I keep reading that everyone says that it doesn't have a power band, sounds like these people are buying to big of a machine for there purpose. I have a 100rx, 130 kombi, and now the 131 I have to say the new motor is hands down the wife, the son, and my favorite machine. The fuel consumption is amazing. In short if you're buying to trim 1 acre or less get the 111rx if you need a big machine this is the answer.

Rated 5 out of 5 by from Great trimmer Stepped up from an FS56 and couldn’t be happier. It has plenty of power, even with the guard off (I’m aware this voids the warranty). I was skeptical about buying a 4 mix due to people saying it’s an “all or nothing” engine, but with the guard off and the right load you can feather the throttle very easily. Only complaint is that the grip is wearing away from only about 10 hours of use. 10/10.

Rated 5 out of 5 by from Weed wack'in Monster This thing is truly one heck of a machine. Before I get into the review of the FS131R, let me shed some background which led me to the purchase of this hoss.About 8 years ago, I purchased a FS45 from my local Ace. It had a hard life for sure. It was run over by my x-wife's car when it was just two weeks old, and I'm sure that added to her x-wife status. After having the FS45 repaired by my local Stihl dealer, it was a great little machine that got the job done around the house for the next several years.Aaaaand then I bought a north GA mountain cabin on 15 acres.... Poor little guy did all he could to clear overgrown weeds and small brush. It spent most of its time bogging trying to cut through the stuff. It was constant full throttle, go in, bog, back out and let it reach speed, then go in, bog, back out and repeat... Briers and small saplings? Forget about it... That had to be hand cut with shears (1000X+, talk about time consuming). The FS45 dealt with the mountain land for about 1.5years before it finally threw in the towel.FS131R...So after the little FS45 weed wacker that could, couldn't anymore, I went to get a replacement. I was initially interested in the FS56 and FS70R, but quickly found out that they were not for me (Not much different than the FS45). They would be great for residential duties, but I needed something that could cut through the nastiest of nasty. That means I needed something that was not cable driven like the FS45, 56 and 70R. I needed something with a steel shaft to run a brush cutter and have the HP to meet all demands. Going through the pro series lineup, I noticed that most trimmers had marginal bumps in HP. However, I certainly noticed the staggering 1/2-HP jump in power going from the 111R's 1.4HP to the 131R's 1.9HP. I told the sales guy: "Yeah, I'm done farting around with those weeds, I'll take the 131R chainsaw on a stick".Operating/experience/performance of the FS131RWhat a hoss. This things got more HP than I have sense. Definitely overkill for your typical around the house jobs, but it's reassuring to know that you can cut down a 100' Oak given enough time.(HP) Not once has it ever bogged on me. Where you hold the throttle is where it keeps the RPM. Full throttle is only used for the brush cutter (Tri-Blade) clearing the nastiest brush and saplings. (Fuel consumption/range) I'm sure the FS131 burns more fuel than my FS45/56, but it the size of the fuel tank allows me to run it literally twice as long before refueling. That is a huge benefit to me as often times I'm a quarter mile away from where I started (gas can).(Throttle manipulation/feathering)One "negative" that a couple of people mentioned with feathering the large motor trimmers is their sensitivity. Unlike the small motors, I'll admit the large motor throttle manipulation/feathering is in fact more sensitive. It is definitely manageable, you just have to get accustom to it. HOWEVER, throttle sensitivity has no impact on how I operate trimmers big or small. After a decade of operating countless trimmers, I always use my middle finger as a mechanical rev limiter for the light stuff. Meaning, with your pointer finger on the throttle trigger, your middle finger sits in between the handle and underside of the throttle trigger. It is a much faster and consistent method to go from idle to half throttle whether using a FS56 or 131R. If you start getting into the real tough stuff, simply move your middle finger out of the way and go full throttle. Wheres the small motor trimmers spend 75% of their time in full throttle, the 131R would need to be full throttle may 10% of the time. That probably also makes a huge difference in fuel efficiency of the 131R, vs the high rpm operation requirement of the smaller motor trimmers.(Starting)The FS131R is definitely easier to start than my previous FS45. The 131 as well as most new models come with an auto choke. That makes it much easier to start rather than manually setting it to choke then rushing to flip it off choke before the engine stalls out. The effort required to pull the cord is so effortless, a 90 year old Nun can do it. (Weight/Balance)At 12lbs, the 131R is a couple of pounds heavier than my previous FS45. This is a good thing and here is why: First off, the trimmer head, as well as it being a steel shaft has more mass. The benefits to the added mass, is less kick once the trimmer engages into the thickets. Not just trimming but edging too. Much less trimmer head bouncing than the cable driven or hollow shaft variants. The sling that the heavier (2-3lbs) steel straight shaft variants come with negate any added LBs. Not only that, but the sling keeps the trimmer perfectly balanced, making extended use a pleasure. I'm a relatively small dude at 150lbs, chicken legs & all, but I had zero fatigue after 6hrs of constant use the other day. I couldn't say the same for the lighter FS45, since it did not come with a sling. (Sound)The sound of this 131 thumper is a huge improvement over the smaller engines. It is a lot quieter with a much lower hefty displacement rumble (for a trimmer anyway). I cant say the same for the smaller displacement, high frequency screaming trimmers that are as pleasant to the ears as a Civic with a fartcan. (Overall)I couldn't be happier with the 131R. For me, it's the perfect machine. It exceeds all of my expectations in a trimmer. It was 2.5X the cost of my previous FS45, but this monster is a whole nother cup of tea. Buy once, cry once. For me, it was absolutely worth every penny plus some. I'd give the FS131R six stars if I could.

Rated 5 out of 5 by from Powerful!! I've been using a different brand line trimmer (Orange in color) around my pond for years and thought I had the best until I used the FS-131. I can honestly say that my line trimmer time has been cut in half. This thing is a BEAST!!! Absolutely No easing into the thick grass or weeds around the pond or outskirts just, hit them and keep going. My previous line trimmer needed a blade to take care of the tough stuff, NOT THIS ONE with .105 line!! It is a litter heaver than my last line trimmer But, a small price to pay for quality and power.

Rated 5 out of 5 by from Not for simple everyday weed eating... This power packed head unit is a beast. WAAAAAY more than what is needed for around the house weed eating. If thats all you need, do not get this. Get one of their smaller models. This beast is heavy, and not designed to run wide open throttle with no/light loads like a typical 2 stroke. This has valves like a 4 stroke, and must have a load to maintain WOT, or you will throw out the valve adjustment and possibly damage the valves/piston. I have the flower bed edger attachment for this and you def need the power of this unit for that. I am thinking of getting a pole saw attachment and the tiller attachment, which i'm sure will also make me happy that i bought this unit. This thing is easy to start, never stalls, hair trigger throttle (which makes it virtually impossible to run half speed for weed eating), large gas tank (needed), and gobs of torque (this is why its valved, to provide low end torque).
