I bought my Westinghouse 18" Tiller today and came home to use it. It was so easy to put together that one doesn't need the directions. It works fantastic and would recommend to anyone with home projects or that are big gardeners.
I just got it yesterday and assembled it easily. I checked it out on a small area and it seems to work just fine and the blades tilled my lawn faster than I thought. Westinghouse is a solid brand so I think it'll perform just fine.
This tiller worked really well in my flower and shrub garden. You have to really hold the handles tight and steady because of the 6 blades tilling the earth. If you till over a lot of weeds or grass, you do have to stop and clean the blades to continue for better results.
