FS-KM Line Head Trimmer is rated 3.4 out of 5 by 52.
Rated 1 out of 5 by from Read review's. It's junk. Hate to admit it, I should have listened to others review's about how bad it is. Junk as far as I'm concerned. Lots of vibration when not wide open throttle. Sounds like its feeding line when it's not full throttle. The vibration is very horrible. Constantly breaking line and having to take head apart, because line breaks clear off. Horrible design for putting on trimmer line or fixing broken trimmer line. You have to use 2 pieces of trimmer line, instead of taking 1 length and just wrapping it around. You have to bend them both to get them to stay in start holes which sucks. Don't even get close to a side walk or curb. Trimmer line will break off. Again, because you have to be full throttle to avoid a lot of vibration. In the beginning I spent more time fixing trimmer line then trimming grass. Now I I have to use it very carefully and hope for the best. Won't let my employees touch it anymore. Took it off the trailer. Can't see paying them to fix trimmer line all day, and I almost thru it across a couple clients yards trying to get my money's worth out of it. Probably just put a brush cutter on it and use the head for other attachments I bought. First stihl product I have purchased and matched it with KM 94R which I do like and it's very light. Other attachments work well. Not very happy about how their attachment system connects and disconnects, but well see over time. I've used many other Stihl products over the years that other people owned, and was happy with them. I'm not saying all Stihl products are bad, just stay clear of this attachment, and Save your money and time unless you enjoy a challenge. Not me. Wish I could get my money back. Not sure if I will buy anymore Stihl products because of 1 bad design, or because I didn't take others review's seriously which is partly my fault. Best use for this product, might just be using it as a golf club to hit beer cans with.

Rated 5 out of 5 by from The string is your problem not the trimmers.... For the 1star reviewers about string problems.Get good string, load your string better, and don't slam your gears on the ground. Stop and pull out the string manually.Best string attachment.

Rated 5 out of 5 by from Does the job well. I cant really complain about this thing. Its probably one of the most reliable line trimmers I have ever used. I don't have problems with the line breaking unless I do something stupid. I can move at a brisk walking pace and not have to worry about an even cut.Love it.

Rated 5 out of 5 by from String trimmer issues I’ve had my 131 for about a year now and love it, I have 3 attachments and plans for at least a 4th. I started with the string trimmer and like all stihl products I own it works very well. That being said operator error, and cheap string can cause headaches. If you wind your string too tight or put too much on a spool you will have problems. But if you have a little common sense, properly mixed fuel and quality consumable materials to go with your quality equipment there is no reason you can enjoy years of hassle free use.

Rated 2 out of 5 by from The string continually binds in the spool and breaks The string continuously binds in the spool requiring a disassembly of the head to rethread. We have tried several different wnd techniques to no avail. We are using Stihl line.

Rated 1 out of 5 by from Cutting line very difficult to advance The cutting line is very difficult, bordering on impossible, to advance on this head trimmer that goes with the Kombi System. I try to advance the line as the instructions state, by tapping the head on the ground while the engine is at full power and it takes multiple time for the line to advance, no matter how much line is already out there. I have only had this unit about a month, and so far I have had to take the head off and pull the line out manually on numerous occasions. . NOT GOOD. I am going to put new line in and see if that helps, but so far, I am very unhappy with the performance of this trimmer.

Rated 5 out of 5 by from Enjoying it So I upgraded from an FS 40c to a KM 91 unit. I of course got the FS KM head. I broke off one side of the string like several people have stated. I had no problems re working the spool to keep the job going. I will admit it was user error with me. Not the trimmer head. Haven’t had a single problem since. I like this attachment a lot.

Rated 1 out of 5 by from Awful trimmer Since we got a bigger yard, I wanted to upgrade from battery-powered serviceable edger to something more powerful and convenient, and based on what I read and heard, this system was the answer. Pleasantly surprised by the power of the KM 111 and was excited to start edging. However, I should've paid more attention to the reviews. I immediately had issues... within the first three minutes of operation I realized it was a bad decision to purchase this. I spent more time stopping and popping the string housing open to feed the lines through. Once I realized I couldn't run it very long before the string wore out all the way to the end, I had to stop OFTEN and see how much length I had, then bump it for added length because it was just chewing through my trimmer string - not in minutes, but in seconds. What should've taken no time to complete ended up taking a lot of time. Very frustrating.
