Today, at a store, I saw this mower parked on a trailer. This thing had one axle, with dual wheels (probably about 36" tall) on each side. It was orange, and resembled a giant old Gravely walk behind tractor, but it had a suspension seat attached to it, that just sort of hung off the back. It had a large deck that was hydraulically driven, and was titled with some sort of name thart gave the connotation that it was designed for hills. It looked like a monster of a mower, and had a larger motor on it, that was perhaps around a 50 hp, or so. Any ideas?
