Are You Ready for a STIHL?

FS 131 R is rated 4.5 out of 5 by 32.
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).

Rated 3 out of 5 by from Lots of Power But Several Issues 6 acres with everything from grass around trees and flowers to thick brush around t posts. Noticed they only put enough gas in to test it. Why not fill it up as a courtesy, or don't test? Doesn't really accomplishing anything. Why not go thru a compete qc, testing all nuts and bolts, etc.? I did it and found several loose. Add brand new line, replacing the old, brittle line (see below). Here is how my 1st use went:1. Tried to use owners manual to understand how to add line. Doesn't tell you. Should be specific to the type of loader you have. Nothing except to bump it to release line. Manual indicates instructions are on bottom of line head??2. Tried to adjust the shoulder strap, but too short to allow me to wear it while weed eating. Have it adjusted as far as possible, but still not long enough. 3. The spacer between the handle and the ring that the strap attaches to, spins freely. Cant hold onto to it (when starting unit or carrying around) because the unit will spin upside down on you. I assume it it there to keep the handle from slipping up toward motor. Also would be a good place to hold it while carrying it around. Now I will try to figure out a way to secure it from spinning. Stihl manual instructs you to get on hands and knees, grab the motor like you are choking something, and trying to pull starter cord. ???4. The line in the head was probably old and broke off inside the head continuously. I ended up carrying a flat head screwdriver in my back pocket so I could stop the unit and get that ridiculously rigid head off. The tabs are not very flexible. Screwdriver does work good. I had to use the weed eater with 1/2 of the line removed. It did better for some reason. I was able to keep that 1/2 line from breaking off inside. My biggest issue (and not Stihl's issue) is that the engine is sooo large (CC size) that you cant feather around flowers and trees. It is very difficult to run at a low speed. If you are doing nothing but rough weeds and brush, it will be more than large enough, but why use a weed eater for that? Just get a mower. If only a little brush, a smaller size unit will work fine. Also, have been reading that 2 strokes have better low end control. I thought I asked the salesman this and was told this unit would do the same thing. One last thing. I am reading a lot about Stihl owners replacing the existing head with competitors speed feed head. Just another example that there is not much difference between Stihl and box store weed eaters. I don't put all blame on Stihl because I should have done my research before buying. I take responsibility for this. Now I own a brush cutter and will go to the store this weekend to look for the competitors with the speed feed head.
