Not sure if Dixon still makes them, but the cone / clutch drive is ingenious. So simple, no hydraulics. They offered them on the smaller units / lower HP but they surely were reliable and a time saver. Funny thing is hydro drives rob horsepower big time. Not the situation with the cone / clutch. Though one neg is not being as friendly on slopes, where as a hydro is more controlling.

Also, most ZTR ride rough so consider the wheel / diam. package, seat.
