KM 90 R is rated 4.9 out of 5 by 85.
Rated 5 out of 5 by from Got one 4 years ago... I'm not the best owner, not the worst. I take care of my KM90 by minimum standards. After every winter, this badboy starts no problem in the spring. I have the weed eater and blower attachments. Absolutely love it! Easy to use, gets the job done on my one acre property. Never used Stihl before this but I'm a believer now. Next purchase will be the pruning attachment, AKA 'chainsaw at the end of a big stick'. Can't wait to have a little fun out there >:-)

Rated 5 out of 5 by from Great Machine Great Machine. I have used the tiller attachment in the garden and it is awesome.

Rated 5 out of 5 by from Really great tool all around!!! I bought my KM 90 with a Power Scythe and the combination of those two things can cut through a lot of material, leaving a clean cut. The powerhead is easy to start and lightweight for the power and torque it puts out. I'm excited to try out other attachments!!

Rated 5 out of 5 by from This thing is a beast! Quit buying other junk! Starts fast and easy and has plenty of power! Don't have a bad thing to say about it! I am sold on Stihl products and have now purchased a chainsaw and a leaf blower!!! Will be getting the brush knife kit!!! Love Stihl!!!

Rated 4 out of 5 by from Good overall This product is great if you are a one man show. Obviously can use only one attachment so not great if you like to share the work. I have had for just over a year and it has worked well, biggest issue was the bolt to attach and un-attach got stripped.

Rated 5 out of 5 by from Makes lawncare as EZ as 123 When you got the correct tool it makes the job easy. This is the first Stihl product I have owned and as long as it continues to prove itself, it won't be the last. I bought the blower attachment, straight shaft trimmer, and straight shaft edger. When I got this thing home and snapped in the edger I was sold. The power behind the blade made it so easy to edge that I had to pick up my pace to keep with it. Before I knew it I was in the neighbors' yard. I equally love the rest of the attachments. The KM 90R even gets used with the blower attachment to dry my Crewmax Tundra after washing. With summer temperatures over 100 degrees and high humidity, this tool gets the job done much quicker. Also, it makes lawncare a lot funner and more enjoyable.

Rated 5 out of 5 by from Great Product If you are in the market for a great multi tool this is it. I have several attachments , pole saw, brush cutter, hedge trimmer, and edger. It does it all, and is great on fuel and is really easy to start. Highly recommend

Rated 5 out of 5 by from Nice unit with many available attachments I very much like the km90r. starts quick and easy and has plenty of power. My only gripe is the price of the km90r+Line head trimmer attachment over the fs90r when the only real difference that I can see is the split shaft. With that said I would still recommend the km90r to anyone wanting to frequently change out attachments.
