I'm kicking around the idea of getting a larger, used self propelled grinder I've kind of narrowed it down to a carlton 7015, 8018 or possibly a rayco RG90 4X4. I'm currently using a tow behind which is working. For the most part, I work in larger lawns and lots. Maybe once a year have to deal with gates,(have an alpine magnum from great scott for that). I anyone has one they are thinking of gettin rid of or replacing one, I may be interested in it. Let me know your thoughts on some of these bigger machines as well, thanks
