PTO = What JT said
Re margegeneverra's comment: A common problem with the RZT's is that water can get in the transmission (especially the left one for some reason) through a vent hole or something on the top of each transmission. Once this happens, it's toast in short order. This occurs most frequently with people who wash their machine, or leave it outside in the elements. And because the transmissions are sealed units, they basically have to be replaced once they've failed.

Kinda make one wonder why they highlight their "deck wash" feature, where you hook up a garden hose to the thing.... Gotta love smart design!
