Using the Drive Wheel Release Valves

WARNING
Hands may become entangled in the rotating drive
components below the engine deck, which could
result in serious injury.
Stop the engine, remove the key, and allow all
moving parts to stop before accessing the drive
wheel release valves.
WARNING
The engine and hydraulic drive units can become
very hot. Touching a hot engine or hydraulic drive
units can cause severe burns.
Allow the engine and hydraulic drive units to cool
completely before accessing the drive wheel release
valves.
The drive wheel release valves are located in the back of
each hydraulic drive unit, under the seat.
Note: Make sure the release valves are in fully
horizontal position when operating the
machine or severe damage to the hydraulic
system can occur.
1. Disengage the PTO (blade control switch) and turn
the ignition key to off. Move the levers to neutral
locked position and apply the parking brake.
