    Amazing yard tool
    I bought the MM 55 over five years ago after renting a mantis for two weekends. I have only changed the spark plug and cleaned the filter a couple times and finally had to take it in for service ... but only because of the ethanol eating away at some of the carburetor parts. My yard has that tough Texas black clay, and Boss grinds right through it. A few of my neighbors have enjoyed my purchase also. I am so pleased with this product, that when it came time to fix my Craftsman trimmer, I just ... read more headed to the Stihl dealer and have not regretted it.

    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 ... read more causing me extra pain. Thanks STHIL!!!

    Glad I bought it.
    I bought the MM 55 Stihl Yard Boss several years ago. It works very well as a cultivator and as an edger for the lawn. It works reasonably well as a tiller in areas where my large rear-tine tiller won't reach, although it takes some work to get it into hard, compacted soil. The only problem I have is that the transmission assembly tends to twist some in relation to the head. I have tried tightening it, but to no avail. This is not a serious problem, but it is an annoyance.

    Just my size
    This works great for my garden and not so huge like my husband's rototiller. My husband however likes to use it too. I just wish that the attachments weren't so expensive.

    As a "broom", this is a great product.
    I purchased the Yard Boss primarily for its broom feature. Having the cultivator blades is an added bonus, but my reason for the purchase was the broom feature. I have a large paving stone patio that was overgrown with moss in the cracks since I was unable to do any maintenance for a year due to an injury. The Yard Boss with the easy start feature works great. My left arm is still less that 100% but I have no trouble starting the Boss. The bristle brush attachment worked very well cleaning up my ... read more patio. So a decided to clear the garage. Once again, the Boss did the job with excellent results. I have yet to try the cultivator, but I bought the Boss expressly for the broom feature.

    A very suprising Tool!
    My wife talked me into buying this tool and I must admit I was very skeptical at first. The local dealer suggested the wheel attachment. So we made the purchase. I'm so very glad my wife talked me into this and thanks to my local dealer for the Wheel kit. I found the yard Boss to be very easy to start and use with plenty of power.As with my other STILH tools this one is a keeper. If you have small jobs maintaining your yard, the Yard Boss is a very versatile tool for all ready established yards. ... read more I now own almost all of the attachments and am very pleased. I would highly reccomd this for maintaing your yard. Makes maintaing my yard fun and easy.
