We have a craftsman tiller, a few years older than the one pictured, but it looks similar to the one pictured, and was the heaviest one sold by Sears at the time. It works well, however, our soil is rocky and although we pick the rocks each year, they are still multiplying, and we break a lot of sheer pins. A lot meaning several a day (we have a really big garden though). I would order extras if you have rocky soil.
Since then we purchased an old troy built and loaned the craftsman out to a family that has better soil. The Craftsman still works fine for them, and the troy built works better going through our rows. We use a different pto tiller for the entire garden.
