FS-KM Line Head Trimmer is rated 3.5 out of 5 by 46.
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.

Rated 1 out of 5 by from *** DO NOT BUY THIS ATTACHMENT *** I own 4 attachments for the Kombi KM 131R system. I love the system over all however I am sorry to say I hate and regret buying the FS-KM Line Head Trimmer. Like many of the other reviews I too spend more time re-feeding the line than I actually do edging. I have tried all the recommendations set forth in the reviews to no avail. Please save yourself the headache and do not buy this head trimmer. I also own the tree hedger, extension pole and the rotatable chain saw and love them. Just don't buy this product until STIHL offers an improved version. I wish I could return it and get my money back.

Rated 2 out of 5 by from Motor runs great, but feeder head needs work. I own a lawn service and wanted a quality tool, so naturally I purchased a Stihl. I purchased the KM 131 power head, the bed edger, the string trimmer, and the BR700. I expected a quality feeder head like the other components. Within one minute of beginning to use the trimmer for the first time, the line broke at the out feed location. I spent more time taking the head apart multiple times at my first customer, than using the trimmer. Not only is it hard to take apart and restring, it's a pain to do. What I don't understand is why they didn't put a speed loader on a commercial unit knowing time is money to us commercial mowers. I've read the review saying to soak the line. I've never had to soak line for any string trimmer I've purchased. Never had this issue with any other string trimmer.

Rated 5 out of 5 by from FS-KM line head trimmer I purchased this trimmer with the KM 94R power head and the HT-KM pole trimmer. I have had this Kombi combination long enough to know that this trimmer is the best trimmer that I’ve used. I find it is easy to replace string in the field, no tools needed. I have used several different replacement strings without any problems with feed. The 94R has more than enough power for this attachment, although it is heavier than a dedicated trimmer. I have not had an issue with either piece in the eight years that I’ve owned them.

Rated 2 out of 5 by from Initial review after using the km91 head with the line trimmer After about 5min of use both lines broke with the line supplied with the unit when purchased. I didn't see any instrcutions but after looking at the trimmer head was able to dissamble the unit and re-thread the line. Both lines broke again within 5min. RE-streaded the line again. This time I tried to advance the line regularly. The trimmer line will break quickly and force you to fix it if you are cutting along any sort of fence/stone/hard edge and let the trimmer get within a couple of inchs. I found if I stayed farther away from things it was less likely to force me to stop and fix it. I had the lines break maybe 5 times for I was able to run the unit long enough to use up the spool. Reloading was easy enough if you read the bottom of the trimmer head spool as it is labeled with instructions to wind the line.I also have a 660cm chain saw which I love and a 56 hedge trimmer which I start up and just trim things because frankly it is fun to use....the trimmer is not so much fun at this point, I am a little disappointed with it to be honest.

Rated 5 out of 5 by from It just works. After having several trimmers over the years and using others at various points in my life, I can honestly say this one is the best. From batter powered, to gas powered, nothing beats this trimmer. Using ONLY STIHL trimmer line, it has always conquered any job I have given it and even though the winding of the trimmer line can get a bit annoying, its far and away worth it to have it simply dominate anything I can put in front of it.
