    Awesome Product
    I purchased the KM 90 R about 4 years ago and it is still running strong. This is a very reliable piece of equipment with minimal maintenance that needs to be done for it. I bought this to replace a Home Depot product that did not hold up. This gets a good deal of usage and I have a large selection of add-ons for it. Best lawn equipment purchase decision I have made in a long time.

    Great power head
    This 91 power head is work horse. No matter what attachment I’ve run it powers through, trimmer, edger, tiller, pole saw. 1 small slight problem, it needed a slight adjustment to stay running. The factory setting on the carb was quite lean for emission reasons I’m sure. It would start, but like to die unless you feathered the throttle a bit till it was warm. I made a small 1/8 th inch turn on the L needle and haven’t had an issue since. I’ve used it almost everyday since I’ve bought it 3 weeks ago.

    Great purchase
    Love this tool. Great power and versatility. Buying ALL the separate attachments certainly adds up a bit too much though.

    This product has met our expectations very well
    After learning about this product we decided to try one for ourselves. It has met all of our expectations as far as the work that it saves us. All the work that it can do we used to do by hand. Thank you for a great product.

    Great product
    I purchased the yard boss for clean up in the garden and it performed excellent. The easy start is just that , very easy. Now I am looking forward to purchasing some of or all the other attachments. This is a great product, just what you would expect from Stihl !

    MUST HAVE
    I was debating whether I would use this extension with my Kombi saw and hedge trimmer. This is a must have attachment. Cost is minimal and I've already used it a few times.. Its one of those things that when you need it you really need it and there's no other real options. Well worth the money and attaches very easy and quickly. Highly recommend.

    Kombi Must Have Attachment
    I purchased this item to help with pruning tree limbs. However, I used it to trim grass as well. If you prefer not to stand in tall grass or a ditch, use this extension to reach out and touch it. . . . works great! I love this attachment for the Kombi setup....

    Unbelievable
    I own a line trimmer head wich works nice for around the house but this thing is awesome around my pond & treeline. Cuts way more than advertised. Limbs the size of your thumb& heavy brush no problem.Good product easy to maintain.

    totally awesome - too much fun.
    have a KM 91 R with 3 point cutter tool... destroys black/salmon berry, and 1/4" dia easy up to 1/2" harder wood with muscle. I think if I had one of the more circular saw type blades I could cut the 1/2" and up saplings ++super easy++. IMHO... you want a good shoulder harness. The bruchcutter can work hard. wear safety glasses, it spits, which means it works.

    Great addition to my KombiSystem set of Tools
    Great deal to purchase as a whole new attachment, it comes with the 4 tooth grass blade, grass guard and a cover to protect the blade. I now have the FS-KM Line Head Trimmer, FS-KM Brushcutter with circular saw Scratcher Tooth Blade and this FS-KM Brushcutter with 4 Tooth Grass Blade. With a quick change I can now use the right tool to cut grass/weeds/sm bushes that grow near the canal behind my house. The only reason I rated it a 4 was that I needed to sharpen the blade after my first use as ... read more it was pushing some of the grass and not cutting it

    good but heavy
    It works really good but it is so heavy after using it for more than 30 mins. Great for reaching those hard to reach areas without getting on a latter.

    Great for getting under heavy growth and cutting the stems.
    I use this alternately with a KM94R and an FS90, when clearing Heavy woody invasives such as Barberry, Multiflora Rose, etc......and I've used it to cut stems over 3/4" in diameter, and given a few seconds it will chew through most anything. The only reservations I have, is that it isn't great cutting through heavy infestations of Stitl Grass, where it drags down as if you were stirring cement with a broom. For areas inhabited with this heavy grass, I use the Three Pronged Brush Blade or ... read more even the Circular Chisel Tooth Saw Blade. The key to succesfuly using any of these Brush Cutters is acheiving a good balance, btw harness and brush cutter so you are able to cut hours at a time w/o fatiguing.

    Lightweight and flexible
    Used this type for years before I retired. With the adjustable cutters I can trim even the tallest of my shrubs, top them off, with many shrubs on my property its very light and well balance in weight you can handle them for hours.

    Excellent product yet again from Stihl
    Bought it the other day been testing on my mothers flower beds due to her bad RA, and have the curve tines needless to say it is ripping right through hard packed Alabama soil like butter. The ext. is heavy wear the strap protect your back. I use greentouch advanced trimmer racks but not recommended to leave on any trimmer rack if you have bump roads like my location just swap over to the pole saw or some other light ext. when carrying on the racks. I use the KM110 head to power these.

    Exceeds my expectations
    My garden is too small for a normal tiller configuration, so I tried this product. It dug into the packed soil with relative ease, ripping through roots from nearby trees with no problem. There is plenty of power. It's pretty well balanced. And it starts with ease. A very dependable unit. I will be buying the chain saw accessory next.

    GREAT PRODUCT A LITTLE AKWARD
    I previously had a competitors tiller attachment which I loved. I love my Kombi Stuff so was actually excited when I had a reason to purchase another attachment after the competitors quit working. With that being said. I do not like the angle of the tiller I am 5'5" and its just hard to get an angle for good torque and even tilling. My other system had a slight bend in the shaft at the head which made it much easier. All in all another great Stihl product just will take a few backaches to get used to it.
