Are You Ready for a STIHL?

AutoCut® Line Head is rated 2.4 out of 5 by 106.
Rated 1 out of 5 by from Terrible line advance design. I borrowed my father-in-law's older Stihl trimmer and loved how it worked and it was light enough for me. Went out and bought the FS 38, I have gotten about 1/2 hour of actual trimming in and several hours of messing with the head and watching u tube videos to try and get it to advance properly. My husband and father in law have tried to get the line to work properly as well, with little luck. Since I recently purchased, about ready to return this product and go buy something that I don't have to struggle with the line. My little, inexpensive rechargeable trimmer has been way less trouble and is way more reliable. I can also buy replacement spools for it at a good price that actually advance.

Rated 1 out of 5 by from Don't try to edge with this product Thought I upgraded to a better trimmer but what a mistake. The trimmer line on the FS 40 constantly jams and breaks off short. Don't even try to edge with this line - it goes for about 2 feet and totally breaks off. Trying tapping a full speed does not work. The line constantly gets tangled and stuck together on the spool, forcing me to stop trimming to rewind the line.

Rated 5 out of 5 by from Never Failed Me I bought my Stihl trimmer and it was equipped with the AutoCut Head when I bought it. The system had worked perfectly from day 1 and I’ve yet to find a problem with it. The parts hold up to some punishing cutting on my 3.7 acre lot, routinely take down tall grass and vines(kudzu is horrible stuff!!) The spoils are easy to remove, reload, replace without tools, and it does not take an MIT education to work it either. Pretty simple stuff really... I’ve used the thicker orange line and currently using the thin green premium line which I really like in it!! I do t know what the others are doing with(to) this thing but it’s been trouble free for me!!

Rated 1 out of 5 by from Worst prodcut desiged EVER DO NOT BUY Con- -Autofeed does not work even at Full Speed-Even using Stihl Line breaks off at the head-Line gets wrapped around itself and not feed even when you carefully restring spoolPro-Power head works fineThis is so frustrating that Stihl does not address this product quality issue

Rated 1 out of 5 by from Terrible! Do not buy! I spend more time stopping, taking the Auto-cut head apart and fixing the stuck line than I do trimming. I can hardly go 100 feet without a problem. Not very “Auto” if you ask me! Currently on the Stihl website looking for an alternative to this terrible product.

Rated 2 out of 5 by from Great trimmer. Lousy instruction manuals Stihl makes great products but for the world of me i can't understand why their owners manuals cant show the current product they're selling. In the past I've had the same problems. It's extremely frustrating to have an owners manual showing a 4 year old product that has nothing pertinent to what you actually do have! WAKE UP STIHL!!!!!

Rated 5 out of 5 by from autocut 25-10 trimmer head I have a Stihl fs 85 and have used several of the autocut 25-10 heads. I have never had a problem .I have probably used at least 10 of them and all have worked as they should. I think this is a fine product.
