How do I use the deck wash system on the TB30R?

After each mowing, drive the tractor to a level spot, disengage the PTO, set the parking brake, and stop the engine. Attach the hose coupler to the water port on the deck surface, turn on the water, then restart the engine, set the throttle to FAST, and engage the PTO for a minimum of two minutes. After washing, keep the cutting deck running for at least two more minutes to allow the underside to thoroughly dry. (Page 24)
