Rated 1 out of 5 by from bought and the first time I tried to run it it wouldn't start well so without even using it I had to take it back to find out why it won't run I paid a lot of money to get a good quality weed Wacker and could have paid a lot less and maybe it would have run very disappointed

Rated 5 out of 5 by from All Around an Excellent Product An "All-Around" Excellent piece of Machinery. The very best of Quality, not to mention Very Durable and Dependable, and backed by a great Warranty. The STIHL FS 131R has plenty of power to cut through some of the toughest weeds, actually not a noticeable difference in power when compared to a FS 250R, but the FS 131R is lighter, weighing close 2 lbs. less than the FS 250R. The Power difference is virtually unnoticeable to me, so I chose the FS 131R considering it has nearly as much power as the FS 250R but weighs considerably less. Also the FS 131R is over $150 cheaper than the FS 250R so it's an unbeatable price compared to other weed eaters. So to sum it up, The STIHL FS 131R is an Amazing Product, it's very, very Dependable and Excellent Quality. It has unbelievably Excellent Power and for the Price compared to other Models and other brands, it's simply an Excellent Value!

Rated 5 out of 5 by from Excellent Trimmer I came from a FS55 with the bicycle handlebars. The FS131 R has much more power and sounds smazing with the 4 MIX engine. I find that the loop handle is significantly more maneuverable than the handlebars. I trim alot of fence and a pond and this is perfect for holding at different angles to get all along the banks and along the fence. The engine starts on the first pull without having to choke it. I am very satisfied with this purchase.

Rated 5 out of 5 by from Unreal Power! First, the negatives, the shaft could be about 6" longer and the throttle is a bit touchy which takes some getting used to. I think that will get better with more time on the machine as i've only handled four yards with it thus far since new. The good-great. This thing has unbelievable power and goes through anything quick, fast and in a hurry. It does burn some gas but I suspect that's what you'll get with any trimmer of this power and torque. I needed a trimmer that could do it all and it is a bit overkill for light trimming but i'm happy to live with that for what it can do to thicker brush just with the factory string loaded on the factory 25-2 cutting head. Bought some .105" to replace the factory line with and probably will do even better with thicker stuff!

Rated 5 out of 5 by from More power than I ever thought I would need I got this model because they didn't have the 111R in stock. I didn't think I would need the power of the 131R. But for $30 more it was worth getting more power just in case I ever need it. I have used it for yard trimming, tall grass trimming, and brush cutting. I have the normal gard and the large gard and I love the large gard. I also have the saw blade for it I haven't used that yet but plan to soon. It starts up fast and runs so smoothly. The four stroke sounds deep and is easier on the ears than other two strokes I have used. The tap to feed string head works really well and is very easy to load. I enjoy using this trimmer unlike every other trimmer I have owned. Stihl has always been recommended to me each time I have bought a new trimmer but I never wanted to spend the money. I am so happy I did this time.

Rated 5 out of 5 by from LOTS OF POWER Hands down this is the best trimmer I have ever used in my life. I recommend this FS 131R as the best trimmer so don't wait go buy one.
Date published: 2017-08-11
Rated 5 out of 5 by from Powerful, reliable and a great value Purchased the FS 131 R to replace my old well used FS110. Was pleasantly surprised with the responsive nearly 2 Hp motor. Using a hedge trimmer attachment it will make quick time in clearing blackberry patches. Love the choke mechanism, makes for easy starts. Prefer this model over handlebar versions...seems like I have more control and the weight is fine. I'm 55 and believe with proper care this will be the last trimmer I'll ever need. Looking forward to using this beast. Extended run time is a plus.
