I’ve seen a lot of TMG products at online auctions and at first was not sure. I bought this tiller and the 4” chipper. It can handle small rocks and doesn’t shear the pin often. My tractor is 33HP and can still handle it. The only reason I why it doesn’t get 5 stars is because of storage and depth adjustments. Depth is manually adjusted with nuts a bolts, I would have preferred a quick built-in system. Also the one metal leg for storing is not ideal, it easily tips and rolls. Storing on a skid with forks doesn’t work the best so I’m going to build a custom wooden box for it for handling.
