Rated 4 out of 5 by from Small tiller for weeding and defining beds I've owned a MM55C for a few years and it's good for weeding beds, enlarging small beds, cutting curves and getting into tight spaces.Pro:LighweightRemovable tinesEasy to cleanDecent powerStarts easily IF you do the proper post season maintenanceVersatile - can be run with 2,3 or 4 tinesFolds up neatly and fits into most car trunks with easeCon:NEEDS A MUD FLAP! I added one because this unit throws dirt all over your feet at full power without a mud flap.Be SURE to run the fuel tank dry before storage and avoid gas/ethanol mixtures. Even 10% ethanol in gas will cause the carb on this unit to foul. I replaced the carb and it ran like new. Took the old one apart and it was totally green inside even with the use of Stabil ethanol stabilizer.

Rated 4 out of 5 by from Nice Machine We really love this machine overall. My wife has used it more than myself so she should be writing this. We use this Stihl MS 55 for our garden tilling after we've planted. Excellent chewing up the ground making for easy weed pulling. The only issue at all is it is a little bit tiring after about 30 to 40 minutes of work. We use the wheels to help adjust for depth control and they work great. It's also nice when you stop tilling to just let the unit rest on the adjustable wheel stand!

Rated 4 out of 5 by from Nice small machine to get in tight spots. I bought the Yard Boss to compliment my full sized tiller. Both do a good job, sometimes you need a small tool and sometimes you need a bigger tool for a bigger job. I have both now. I'm really pleased so far with the performance of the YB. My only suggestion to Stihl would be a lower price would seal the deal for a solid 5 * rating. Good job though.

Rated 3 out of 5 by from Good and Bad I was tossing around whether to buy a new Kombi-system powerhead or this unit to control my Powersweep attachment. The only reason I considered this unit is the Powersweep unit gets heavy and bulky after using for awhile. I thought the wheel attachment on this would make that task easier. Using the powerbroom or Bristle Brush on a hard surface is fine. As for removing gravel from grass there is no good angle with this unit. You are constantly fighting the unit in an unnatural motion. Trying to get gravel out of grass is much easier with the handheld Kombi-motor. The unit is good and seems to powerful but unfortunately the main reason I bought the unit is a waste for me. I should have bought another Kombi-motor to use with 1of my 8 attachments. Stihl is good quality, unfortunately in my application I have buyers remorse with this unit.
