Why buy a fleet of outdoor power equipment when one system will do? The STIHL YARD BOSS® is a gardening multi-task tool system that’s transforming lawns and redefining lawn care. Featuring a universal power train, this yard care system accepts a wide range of attachments. Now you can complete a variety of lawn and garden tasks with only one machine to operate and maintain. Cultivate, edge, aerate, dethatch, clean up and more. To help you identify model features, look for these corresponding symbols: C = Comfort feature and E = Easy2Start™.

Powered by a STIHL HomeScaper Series™ engine, the STIHL YARD BOSS® has the power to handle tough jobs. Behind all the power, this multi-task tool also features a curved, ergonomic handle design, adding comfort to whatever task your tool is performing. The handles also fold down, making the STIHL YARD BOSS® exceptionally easy to store and transport.

    Easy to start and use.
    The Easy2Start system is great! I purchased the optional wheels and find that the placement of the wheels help me control the depth of cultivation. Without the wheels touching the ground at all I do have trouble controlling the speed, as you squeeze the throttle with your right hand and I am unable to squeeze partially and still maintain enough grip to control the machine. I also wish it wasn't so loud! My husband tells me that is normal and I am too sensitive to noise, haha

    My wife loves it
    This is a great cultivator. We've only used it as a cultivator and it is so easy to use that my wife won't let me use it. She loves it and I do too. We have 5 above ground vegetable garden boxes and she's able to lift it in and out without any problems. It starts very easily even after sitting out the winter in our shed through the Minnesota winters with fuel in the tank. I run only non-oxy fuel in it and would never use oxyginated fuel in any 2-stroke.

    Exceeds Expectations
    I use my MM 55 only as a cultivator/tiller. It is VERY handy to go between rows. Starts easily even after not running for weeks. Very portable. Perfect for getting in to tight places or working up a small area. Glad I bought it.

    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.

    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.

    Well crafted and durable
    Very well crafted tool. I love the light weight and maneuver ability. A little pricey but would be fine if it had the option of accessories as a base price. I had to order the heavier tines for what I wanted. Stihl was timely with getting the out of stock product to me. My dad trusted stihl and I do too.
