Rated 1 out of 5 by from Runs and cuts well - when you can get the line to feed Purchased a FS56RC trimmer, pleased with how easy it starts and it seems to have plenty of power. Unfortunately the auto cut feature does not work well, I have tapped on the ground, banged it on the ground, high RPM low RPM, same results. Spent 30 minutes on hold with Stihl tech support, finally gave up and left my number. I have read quite a few reviews, sounds like I am not alone. Looks like the response from Stihl is to tap at high RPM, note that page 35 of the manual instructs one to do it "with the engine running" and page 31 of the manual instructs not to run at high RPM for the first 3 tank fillings. Don't think it's my line winding skill, as I am still on the original new machine load. Guess I get to make the 1 hour drive back to the dealer. Funny, our old weed eater was a bump feed, ran for years without problems. Expected better from Stihl.

Rated 5 out of 5 by from Excellent product I have owned a FSE-60 trimmer with the auto cut head for 5 years, using it weekly all summer long edging 400 ft. of concrete and 200 ft. of trimming, and have never had a problem loading string or advancing line, I do bump it firmly on concrete, asphalt or dirt. I would estimate another 2 years use before replacing the AutoCut C head.

Rated 2 out of 5 by from FS-40C Purchased Stihl Fs-40C bushcutter a few months ago. Very soon the cutter head would not feed the line. I always have to stop the motor and manually feed the line. The bumper/bolt combo came apart. I carried the plastic bumper in my pocket to tighten the bolt after removing it to obtain the line. Yesterday I dropped the bolt and could not fine it. It appears the bolt is a dedicated one, and cannot be obtained locally. I went to the local dealer for a new bolt. He had no idea that there was a bolt on the cutter head, and said that he had none. He checked Stihl online and could not find one. The metal grommets on the cutter head are nearly worn away. I am disappointed that this machine is not of better quality. I think more engineering is need to much improvement it.

Rated 1 out of 5 by from Same complaint everyone else has. Doesn't feed the line even when used correctly This Line head came with my dad's new Stihl FS38, and despite using the correct size of line and installing the line correctly, and having the engine full speed to do the 'bump' of the line head on the ground to feed the line, it only worked about 5 out of 50 times of use. After that, I got tired of tipping the weed cutter upside down and pulling the line out manually. It got to the point where I couldn't even pull the line out manually, I had to take it apart to get any line out. I got fed up with the whole thing and ended up buying a Dura-Cut line head with the Dura-Cut, single line that you just pop right into place. The price I paid for those Dura-Cut lines, I thought they would last longer, but they didn't last any longer than regular line that comes in spools.

Rated 1 out of 5 by from Does not function properly I have a Stihl FS 45, purchased 12/21/09. It worked fine until yesterday. On 2/22/17 I purchased an Autocut C 5-2, yester was the first time I used it. It would not feed the line. I took it apart to check the line, and replaced the line with new line still would not feed. I took the head only to the dealer where I bought it, they checked it over and could fine no problem. I purchased a new autocut because to finish my lawn. I installed it on my trimmer and it would not feed line. I managed to pull out enough line to finish my lawn. This morning I call your tech rep. he told me that you have to run the trimmer at full throttle. advance the string. The instruction sheet that came with the autocut said about have to use full throttle.. I am going to take the trimmer to the dealer and see if they can make it work. If not I will just buy a new trimmer, but not a Stihl.Frank D. ThurlowVista, CA

Rated 1 out of 5 by from Line breaks too easily! Though I consider Stihl products to be the best of their kind,this trimmer head is, by far, the worst I've ever used, and that's saying a lot -- I'm 70 years old and have had lots of trimmers through the years. The line frequently breaks right at the head, requiring the head to be taken apart and the line re-threaded. This happens every few minutes, which means that I spend 30 minutes doing a 10 minute job. I will be replacing the head in the very near future.

Rated 5 out of 5 by from I use the auto cut 25-2 Best head out there. Take time winding the line on the spool use the .095 round line from stihl if you use the professional trimmers. Roll one half and then the other. I never have any problem in grass or weeds with it bumping out. Now if you hit against fences or tree stumps it may cause a problem. But in grass and green weeds, this head on my fs90r and my fs130r will stand up until I run out of string. It isn't real hard to spool either. (I suggest any one having problems to look at the Videos or get the fix cut model. They are real easy such as the duro cut models.) I bought a couple of extra heads to switch out so I don't have to stop. I'd rather have these heads because they are durable and they don't get tangled up like models with both lines are wound up together and become welded or knotted. They occasionally have problems but it usually user error to much string or not taking care to put it on evenly.Great product!!!

Rated 1 out of 5 by from I believe in your product. Your chainsaws are awesome. So based on this I bought a fs38 trimmer from the get go the autofeed head was unreliable. It . The trimmer head is poorly designed. It will not advance line no matter how many times you bump it. I went back to my John deer/ stihl dealer and asked about a better head and was informed that this was the only head made for it. Unacceptable from a company of your stature. The trimmer itself is great.
