Rated 5 out of 5 by Weeds fear it and owner's will Love it. This is Fantastic. The Best I have ever had. I affectionately call this weed eater Vicious because of how it takes out almost all the weeds. You can move it left right, forward or backwards and it cuts a large SWAT of weeds. I find that if I rev it up just a little as I'm cutting the weeds it does a better job and I save on wearing out the grass cutting rline. July 15, 2015
Rated 5 out of 5 by Just what I needed I have used my Yard Boss for only about 4-8 hours a year for the past 4 years. It is very powerful considering how light it is. It is very convenient for to use - Always starts - Always performs.It has saved me a ton of work - And made my wife very happy with the loose dirt in her flower beds June 18, 2015
Rated 5 out of 5 by 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 different Stihl products now and have no issues with any of them. June 7, 2015
Rated 5 out of 5 by Outstanding tiller Very happy with this tiller compared to other models. Has lots of power and will tear through grass with ease when putting in new flower beds. We tilled good soil into pure clay and we've been extremely happy with the results. June 6, 2015
Rated 5 out of 5 by 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. June 5, 2015
Rated 5 out of 5 by Great tiller for small garden I have a raised bed garden plot. This has great power and tills like a charm. the wheel attachment makes it super easy to handle. Easy to move from bed to bed. Narrow enough to get into small spots but large enough to till a nice swath. June 3, 2015
Rated 1 out of 5 by It's collecting dust in the garage. I basically sold it to myself. I worked in a Stihl dealership. I bought this thing in 2006 and it's hardly had 1/2 hour of use since I bought it. It will not start. The dealer want's a fortune just to LOOK at it. I wish they would simply come and get it and refund my purchase price. I am sorry I bought it. June 3, 2015
Rated 5 out of 5 by 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. June 1, 2015
