The STIHL Easy2Start™ system provides a fast and almost effortless start with a gentle pull of the cord, making managing your landscape a breeze. When finished, the STIHL MM 56 C-E YARD BOSS® folds easily for compact storage and transport.

MM 56 C-E STIHL YARD BOSS® is rated 4.6 out of 5 by 25.
Rated 5 out of 5 by from Tough, versatile, reliable, easy to use By far the best little cultivator I’ve ever used. Does a number of tasks and never feels under powered. Makes tilling for gardening and landscaping a cinch. Lightweight and slim construction so it fits in to tight places easily also folds up so storage space isn’t much of an issue. Zero regrets. Love it.

Rated 5 out of 5 by from The Yard Boss is a wonderful peice of equipment. This is my second Yard Boss, and this one is just as wonderful as the mm55. Easy to start and plenty of power. I would recommend this mm56 to any one who loves gardening in a small garden.

Rated 5 out of 5 by from This machine is amazing I bought one of these after my homeowner version from a big box store failed. I can't believe the difference. It fired up right away and tore through everything I threw at it with ease. I tilled up several flower beds, some with hard compacted rocky soil. With my old machine I would feel beat up after just 30 minutes of use. With the Stihl I could go all day, very easy to use.

Rated 4 out of 5 by from Versatility We bought the Yard Boss and added the thatcher attachment. Living in the Pacific Northwest we fight thatch and moss continually. Great tool for getting moss and dead thatch material removed so our turf can thrive. Lightweight unit easy to do small areas as needed.

Rated 5 out of 5 by from Easy to Start & Use, Makes Yard Work Easier & Less Stressful I bought this product in APR 2017, and also picked up the 'Dethatcher' to go with it.I typically use this product 3-4 times per year with the dethatcher to help aerate the yard, break up leaves, needles, moss, weeds, and various vine species that grow on the ground.It truly is an Outstanding product. It works better than I could have hoped for. Regrettably, I have not used any other attachment than the detatcher, but I am confident, if I did, that the Yard Boss would do the job justice!

Rated 5 out of 5 by from Tiller Did a 10x20 garden with ease . There were no rocks and soils been tilled for years but didn’t have a garden for two years and yard boss tilled it up easily . Easy storage . The only thing they charge extra for the wheel kit and doesn’t look like it would work to good without it so just include it.
