Rated 5 out of 5 by Great piece of equipment I have been wanting one of these along with a power broom for the past couple of years, After breaking down and finally buying one it is everything I expected. The Km90 with the power broom cut the job by 3/4 s of the time. Going to add a few more attachment expect nothing but the best. The edger and fs-km line head trimmer for sure. April 18, 2014
Rated 5 out of 5 by Very easy to start This unit is very easy to start and has several attachments that provide the owner with great utility. February 27, 2014
Rated 4 out of 5 by KM 90 Mulitasking I have owned my KM90 for 6 years now, and it has performed many different task. From string trimming to trim saw, edging, and articulation hedge trimmer it has always been a dependable go to machine. February 25, 2014
Rated 4 out of 5 by Room for improvement The overall performance of the KR 90 Kombimotor has been fine but the plastic coupler that secures the accessories to the motor is weak and wears out quickly causing the string trimmer ,etc to spin on the shaft. Replacing the coupler with one made of steel would greatly improve performance at a minimal cost. December 25, 2013
Rated 5 out of 5 by ALL you'll ever need !!! All you should ever need in taking care of your yard. So easy to change our the attachments allowing you to multi-task. Wish I had this years earlier. October 30, 2013
Rated 5 out of 5 by KM90R More power than you'll need. Bought the KM90R with blower, straight shaft trimmer, edger, adjustable hedge trimmer, and 3 foot shaft extension for my large corner lot. My concern was will it power larger attachments like a cultivator. After using it for 2 years, I see no need for a larger unit - it never bogs down. Don't know why people buy the larger engines. I love the the sound of 4 stroke and it's quiet. Buy the HP Ultra engine oil with purchase to double your warranty. Just 1 bottle in a gallon of gas and there's no oil changes to worry about. All the Stihl reviews on engines or attachments are believable (for the most part). Read them; learn from them and ask dealer good questions. Remember, nothing is perfect, but this product and the service/dealers are every bit worth what I paid for - a lifetime product. Caution: Make sure attachment is FULLY inserted into shaft, not partially. Make a magic marker line on shaft as a reminder. Keep this coupling lubed, and follow all maintenance/lube instructions as you would for your brand new Caddy. October 2, 2013
Rated 5 out of 5 by Great product all around! Great macine with excelent power and fuel economy. I would recomend the Kombi system to anyone looking for a quality versitle product September 18, 2013
Rated 5 out of 5 by Nice machine Bought for the flexabikty. Love the pole saw attachment. Was clearing brush on a private trophy trout stream and a young guide grabbed my powerhead and fell into the water submerging my unit. Cranked it right up and ran the rest of the day !! Love my Stihl. Can't wait to get more attachments September 16, 2013
