FS-KM Line Head Trimmer is rated 3.5 out of 5 by 55.
Rated 5 out of 5 by from Stop writing reviews about line! I’ve run stihl for years and had no problems with them, I’m a lawn care professional that uses them everyday. I wanted to come check out the reviews to only see people giving one star because of the string. Use different string or don’t put the string to close to the surface or fences. Overall very nice attachment

Rated 5 out of 5 by from Same quality as the stand alone units I have owned a lawn business for 24 years. This piece of gear is every bit as good as the heads on the stihl stand alone line trimmers. I own 3 of these. The problems listed are common problems for inexperienced and experienced users.The vibration noted in one of the ratings is caused by having two different length strings wound in the spool. You MUST have two exact length of strings wound on opposite sides of the head or you will get a heavy vibration.Constant string breakage: string may be wound too tight causing it to overlap in the spool and not allowing the feed Loosely wind the string like you would when you roll up a garden hose.String not feeding when you tap it on the ground: this most likely is caused because grass clippings get inside the head underneath the spring this prevents the head from fully moving upward when tapped not allowing it to rotate to the next slot everytime you open the head to add string blow out the area around the string with your mouth. If wet you may need to scrape out with a flat head screw driver.

Rated 1 out of 5 by from Constant cord breakage/feed feature does not work Heard good things about Stihl, so bought top of line Kombi system. Edger is great, motor head reliable, BUT THE STRAIGHT TRIMMER HEAD SUCKS! Can't trim for more than 5 minutes before string breaks, tapping head for "auto feed" does nothing, so I have to stop and pull trimmer attatchment off, pull trimmer head off, pop out spool, pull out more string, put everything back together, and try again, only to have string break within another 3-5 minutes of trimming! COME ON, PEOPLE - this is NOT impressing anyone. Would like Stihl folks to send me a trimmer head that works...considering how much this attatchment cost. My local dealership has not been helpful- but this is a manufacturing flaw, so not dealer's problem...they only sell what Stihl provides them. HELP, HELP, HELP!!!

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.
