Rated 5 out of 5 by I purchased the Yard Boss to save myself more pain. I was suffered a head & back injury a number of years ago, when I tried to use a regular weed eater it caused me extra pain. While on vacation I found the yard Boss while walking through a store taking a break (stretching my legs). It has been a life saver, not too mention to tiller attachment. Since the wife & I retired and moved to the country I've needed something to help me get a little garden started. The Yard Boss allows me to complete my yard work and gardening without killing myself or causing me extra pain. Thanks STHIL!!! June 26, 2014
Rated 5 out of 5 by Outstanding tool for many applications. This is undoubtedly my favorite tool. The problem is all my neighbors want to borrow it too often. I hope my wife of 40 years never asks me to choose between her and my Yard Boss. June 26, 2014
Rated 5 out of 5 by Yard Boss, best mother's day present yet! Now some of you may be shaking your heads at my title, but let me tell you I love my Yard Boss. It's small enough for me to handle as a female without feeling like I'm being beat up (I'm 5'5"), big enough to get the job done. I work hard and expect my tools to keep up with me and this one does. I've used bigger tillers but felt like the tiller was using me. This one is easy to start, runs like a champ, and makes gardening so much easier. I've used it to help clear up a planting bed gone wild with weeds and to do some regular cultivating in a more managed bed and the results are great. It's small enough to maneuver around existing plantings without damaging them, strong enough to do a small garden without taking all day. One suggestion, spend a few extra dollars and fill this with premium fuel with NO ETHANOL. It really does make a huge difference in these small engines. June 10, 2014
Rated 1 out of 5 by Not a good product I bought this piece of equipment 4 years ago to utilize in small raised beds.....Worked pretty well the 4-6 hours I used the first year....Following summer, would not start....Was advised leaving untreated gas in unit over winter would foul carburetor.....Replaced carburetor and used approximately 4 hours during summer with no further issues.....Left fuel stabilized gas in unit....Following summer, would not start.....Advised leaving stabilized gas in unit was issued and to take unit and run out of fuel for winter storage....Replaced carburetor and used approximately 4 hours with no issues.....Ran unit completely our of fuel (even though I was taught never to run a unit out of fuel because it leans out the engine and is hard on it) and stored for winter.....Unit started this spring for tilling beds.....Used two hours but noticed a small gas leak around the carburetor.....Two weeks later just pulled out to use again for tilling a couple of extra beds and noticed that all of the fuel leaked out of the unit....Put more fuel in, noticed larger leak and gas line not holding pressure and will not start....Cannot see where leak is coming from but all lines are connected from tank to carburetor and lines look good......Unable to till my beds as needed and back to service store again tomorrow......I have maybe 30 hours use on this unit and have determined this is one of the most unreliable pieces of equipment I have ever purchased..... Seems to work pretty well when running but I now hate the thought of ever needing to pull it from out of the shed to use....Never seems to work when needed.....I commented last year to the service store that I bought another name brand weed eater 6 years ago and have used approximately 6 hours per week, 9 months of the year for the past six years.....Always starts, performs well, and merely store in the shed at the end of the summer season without worrying about the gas to include adding any stabilizer or draining the tank or carburetor......I just set it against the wall and come back in the spring, turn on the switch, choke and crank a few times and it starts right up and performs well,,,,Never even replaced a spark plug, just weed eater line......I will try one more service (and most likely a third carburetor replacement)....The next time needed and does not work will find the unit meeting a trip to the dump.....I will just have to chalk this one up to experience and knowing to never buy another Stihl product........

Rated 2 out of 5 by Broke down in only 2 years and 5 months - low quality This tiller started leaking fuel and wouldn't start after only occasional use over 2 years and 5 months. The dealer wouldn't honor the extended four-year warranty, which I should have received because I bought the Stihl oil at the time of purchase.This thing broke only 5 months outside of the two-year warranty. I only have a couple small raised beds, so it hasn't been used very much.The dealer replaced the carb and coil and charged me nearly two hundred dollars. That's well over half the cost of the item when it was new.This really is a low-quality tiller that isn't worth the cost and doesn't deserve the Stihl name.It worked fine for tilling garden beds, but it's not even up to a homeowner level of quality.

Rated 5 out of 5 by Easy to use I purchase this to replace my 5 year old homelite, which I was very glad to replace. I was considering a couple other replacement tillers. I have to say I own a Stihl O42 chain saw and a Sthil FS90 weed-eater, but never considered a Sthil cultivator until I my local dealer sugested it to me. It looked impressive but so did alot of others, but I decided to check the internet for reviews and sales. No sales but the reviews were good. Friends recomended another tiller was the way to go, but my chain saw is over 20 years old and the weed-eater is at least 7 years old with no major problems so I went with the MM 55 c. It is lite, starts easily with a couple of pulls and works the soil nicely. I really like the handle configuration which makes it easy to control, plus it folds up making it nice to carry and hang up in the barn. All n all it is a great tiller / cultivator for flower beds and gardens.The only issue I have is the weight. It digs in fine, but a little more weight would help. Stihl sells a weight kit if it becomes a big problem. May 4, 2014
Rated 1 out of 5 by questiionable design poorly engineeredI bought my stihl in October of 2013, when it was on sale at my local dealer. last week April of 2014 I first set out to use my MM55 in the garden. My garden is very small, 200 sq. ft. but there are some rocks in it. Most of the rocks are small, but every once in a while there is one about 4 inches. Before I finished my second tank of fuel in a brand new tiller the gears in the head broke when they hit a rock. The customer service told me this tiller is not designed to work in soil where there is rock, which would make it useless to me as all my soil has some rocks. What has to be obvious is that the rock did not break the gear, but rather the engine did. The rock merely stoped the tine from turning. It was the torque of the engine that broke the gear. If the gear can not handle the torque of the engine then there should be a shear pin or someother design feature to protect the gears. I will take this to my dealer on monday and see if it is covered under the warranty, but i'm confident it will occur again as the engineering behind the design is flawed. April 14, 2014
