We purchase a Great Dane Super Surfer earlier this year and the dealership had an Eastman commercial mower there. This thing looked like a tank with wheels. The one that was there was a push one, but they also have a self-propelled model. The deck seamed really solid, ball bearing wheels and a nice 6hp Kawasaki motor. This is the only place that I have seen them (and maybe with good reason). I did a search on LS and found a couple of mentions, but not much. Is anybody using them?
