Rated 5 out of 5 by from A work Horse for getting garden cleaned up. My Troybilt is and older model "Horse" that I acquired in 1984. The machine is still going strong and will attempt to till my garden again for the close of the season. My garden plot is a 100' by 100'. I would recommend a Troybilt machine to anyone that wants a tiller.

Rated 5 out of 5 by from A great machine! I bought this tiller two years ago to better till my 1000 sq. ft. garden and to "break" new ground. The machine performs beyond expectations. We have put in a new potato patch, leek and horseradish gardens and have used the tiller to level and prepare areas for lawn and general soil augmentation. I cannot say enough about this machine. It starts everytime with a pull and cleans up very well. i service it before winter and it is ready to go in the spring. Reliable.......

Rated 5 out of 5 by from Best I've ever had!!!!!!! When I saw the price I kinda thought "yikes", but you get what you pay for!!!! The BIGGEST benefit for me, at my Senior age, is the EASE of operation!!! Both forward and back are powered!!! Then there's the Honda engine, which we ALL know will generally out-live its owner!!!!! The first couple years I only ran it in the Spring, and even though it sat up in the meantime, it fired RIGHT up!!!!!! The Counter-Rotation pulls the tines into the dirt so you don't have to press down!!!!! I don't think there's a better tiller ANYWHERE!!!!! And by the way, I live in pure CLAY!!!!! 5 STARS!!!!!!

Rated 4 out of 5 by from My proline I bought this machine about a year ago to replace my old bronco which I thought after 25yrs had locked up. It's still working today for my cousin. Anyhow back to the Proline. This machine digs in fast and works hard. Easy to use but could be made a lot more effective if it had frame weights like my old Bronco had. It needs weight over the tires to help pull it forward. I find myself pushing it as it would dig straight to China Love the machine wish you made frame weights!

Rated 5 out of 5 by from Honda engine big plus This is the second Troy-Bilt tiller, the first having a Brigg&Stratton engine. My second and latest Troy-Bilt comes with a Honda engine. What a difference. Starts one pull every time. Much better engine and easy starts. When the cord is pulled the exhaust valve is opened a bit making it some much easier to start. No comparison. Counter rotating tines (CRT) is the only way to go for tough jobs, cuts through even tall fescue like it's not even there. Try that with a shovel some time and you'll appreciate this tiller. Great for making berms as well. Very well built tiller and comes with a reverse gear as well. Thumbs up all the way, this is the tiller to have for tough jobs.

Rated 5 out of 5 by from Easy to use Bought this in May and have used it several times. Lightweight enough that the grandchildren can use it safely. Starts with one pull, tills the ground as deep as you want it, easy to use, Bought it at Hardware Hank in Thief River Falls, MN and had excellent service from them.
