Rated 5 out of 5 by from Works well for cutting brush I bought this along with a bunch of other attachments for my new kombi system. I am using it with the km 111 power head. I have not experienced any vibration issues as mentioned by other reviewers. I think that is a blade installation alignment issue they are having. Anyway, I've been using this with my 111 and it has plenty of smooth power. When you get the shoulder strap adjusted correctly it swings effortlessly and cuts through the pricker-filled brush I have been clearing. I used to own a professional dedicated brush cutter by another brand. I accidentally ran it over with my diesel tractor. I didn't think this unit could match that dedicated unit but I was wrong. It's a great product and I am very pleased with it. My shed is starting to look like a Stihl showroom. But Stihl has earned it through Excellent and reliable products and service. A solid purchase.

Rated 5 out of 5 by from After re-centering blade to eliminate bad wobble vibration it's great I have several attachments for the kombi-system. I found myself with a brush problem and decided to give this fs-km (4-blade) attachment a try. I thought it was a little bit pricey, especially when you buy an actual brush cutting blade, but it was well worth it after resolving my horrendous vibration/wobble when I first started it up.My attachment came from ACE Hardware Dealer pre-assembled with a separate zip lock baggie containing the manual, a wrench, screwdriver, and eye protection glasses. When I got it home I read through the manual like a good boy and discovered that the brush cutter blade is actually NOT what comes on this baby. The 4-blade cutter is for grasses and twiggy weeds. The actual brush cutter, the one that gets through the nasty brush, is actually called a brush knife and it costs and extra $34.00! Ugh. You'll know it when you see it, it's a wicked looking three blade affair that a giant ninja might throw at an enemy. Though I bought the actual brush knife, I decided to test out the 4 edge blade that comes stock with the FS-KM. When I first started the trimmer, I had this awful vibration as soon as I gave it a little gas. I mean it was awful. Something was wrong. It turns out that the blade was installed off-center. Once I loosened up the main nut using the included tools, it was a piece of cake to recenter the blade properly and retighten. Now, after starting up the machine, the operation was smooth as silk - NO Vibration - well, other than what you normally feel while using the thing for an hour!With the unit running properly, I headed straight for some monkey grass and some sizable weeds. The grass blade that came with it performed beautifully and made short work of these plants the give my string trimmer fits. Nice addition. Just for grins I did hit a few 3/8-1/2 in stalky young saplings and Yaupon and it did okay with good higher rpm and firm sweep to the left. I ran a full tank of fuel cutting and clearing with the FS-KM and the stock 4-edge blade. It worked much better than I imagined. I cannot understand why I didn't get one of these suckers years ago. 1/2 the time to clear vs string trimmer. I will say, that you want to be sure to make this the last thing you plan to do for the day because your arms will be useless noodles afterward if your experience is the same as mine. I need both hands to avoid spilling my drink!The blades are reversible when they get dull, and you can sharpen them too.Can't wait to try the actual brush knife now! ;)

Rated 4 out of 5 by from Good Piece of equipment for short duration jobs. I have 5 acres which requires spot clearing throughout the year. The power of the cutting attachment depends on the head you use it with.There is a huge vibration when using it...even from just starting it so you will need some gloves which help relieve the vibration. The vibration makes it so you have to keep reinserting the attachment into the drive head.This is good for exactly what it was made for...a quick change piece of yard equipment that is needed for small area beautification.

Rated 5 out of 5 by from Exceeded expectations I bought this attachment with a 130R to cut Manzanita, and small new growth oak, fir, and cedar trees. It tackled everything with no problem, even cutting material over 1 1/2" in diameter. It's new so I don't know how long it will hold up, but so far, so good.

Rated 5 out of 5 by from This product is the best thing that was ever made. Purchased this product when I purchased the KM 130 R Kombi System .Also purchased the HT-Km pole pruner, the FS-KM Line head trimmer, The HL-KM 135 degree Adjustable Hedge trimmer .And the PP 600 telescoping pole. I will give them all a rating of excellent.They work great. The are easy to attach and make short work on everything.

Rated 5 out of 5 by from A Great Attachment Originally bought KM 55 powerhead with straight shaft trimmer 20 years ago. When I needed a blade attachment last year, I returned to Reynolds in Fishers, Indiana. The salesman who helped me with original purchase still had record of my purchase and recommended this blade. Works awesome on tall weeds and brush. Can't say enough about the professionalism of independent Stihl dealers. Go to big box stores for insulation and drywall. For quality tools to last, Stihl dealer is the only way to go!

Rated 5 out of 5 by from Another great product from Sihl Great addition to my KombiSystem. I have a KM55 powerhead and it has plenty of power to do the job. Although this combo is a tad bit tiresome after use. Overall I've accomplished what I needed to do.
