The thing is a beast and is a commercial quality build. It is a simple build that eliminates alot of things that could go wrong. Admittedly the only other grinder I have owned/operated is a vermeer SC252. And it was a much more expensive machine that saw alot of wrench time. The woodland mills grinder will outwork that 252 but only in its own environment. I wouldnt consider it a money maker unless you cherry pick your jobs. The customer may not like ruts in their yard, may not have ample parking, may not have the needed accessability, may not like the relatively shallow depth, may have trees so large that a sweep would work better, may have really humpy lumpy ground and may find someone showing up with this contraption on a tractor a little odd. Im just being a little realalistic. It is the perfect tool for my intended purpose. Admittedly i have used it to earn a few dollars from neighbors that grew tired of mowing around ten year old stumps, but their landscape is about the same as mine.
