Hi, I'm interested in a European technology that is fairly new to the U.S.: stone buriers. They are a type of tiller that buries stones, roots, and even existing turf under six inches of tilled soil, leaving the area ready for seeding. Most can be adapted to seed as they work, too. Has anyone here tried such a machine? How well did it work? Thanks for any experiences/advice. I don't want to invest in this tool until I have a better idea of how well it works.
