    Garden boxes
    Absolutely the right tool for the job. Working great in my fairly large above ground garden boxes. It's lightweight and can easily be lifted into and out of the boxes. Bought the other set of tines for pulverizing the mix of topsoil, peat and composted cow manure. This tiller makes light work in turning over and freshening up the top 4-5 inches, which is really all you need. Very happy with this purchase.

    Replaced 3 tools in my shed
    Have had this about a month now. I bought it to replace a string trimmer mower and 2 another brands tillers. Purchased the trimmer head and a cutting blade at the same time. The videos show tilling in the forward direction on You Tube but that is WRONG. You have to pull the tiller back just like the the other brands tillers so it was not a big deal. The best part for me is being able to replace 3 tools taking up space in one package.

    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.

    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!!!

    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.

    This product preforms great and has great accessories
    I have been researching mini cultivators for a while and this was at the top of the list. I have a medium size garden and this machine allows me to put the most into my garden without having to give up space to get a larger tiller in between the rows. The accessories that are available with this tool are the reason for purchasing it becauset it will save me in time and labor to care for my garden and lawn. Being able to use one machine to do several jobs is a huge benefit. I own several ... read more different Stihl products now and have no issues with any of them.
