Interesting...When you spot spin you would have to be careful not to pull one lever back too much or you would reverse that wheel. I really think the rio switch is unworkable for ZTR mowers as a practical matter. Some of the rio switches on tractor style mowers had to be held in the whole time when reversing, but Cub Cadet has a new way. Turn the key to the center position, press the rio switch, and the pto will stay in while reversing until the key or PTO is either turned off or the key to another position.

I think I will get a commercial for my next mower due to the blade tip speed, better utilization of HP, and ability to cut heavier grass more cleanly. Might even be a diesel, since my present mowers seem to burn more gas than my F-150.
