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 that the release valves are in the 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 the neutral
locked position and set the parking brake. Remove the
key.

Using the Side Discharge

The mower has a hinged grass deflector that disperses
clippings to the side and down toward the turf.
DANGER
Without a grass deflector, discharge cover, or
complete grass catcher assembly mounted in
place, you and others are exposed to blade contact
and thrown debris. Contact with rotating mower
blade(s) and thrown debris will cause injury or
death.
• Never remove the grass deflector from the mower
because the grass deflector routes material down
toward the turf. If the grass deflector is ever
damaged, replace it immediately.
• Never put your hands or feet under the mower.
• Never try to clear the discharge area or mower
blades unless you move the power take off (blade
control switch (PTO) to the off position, rotate
the ignition key to off and remove the key.
• Make sure the grass deflector is in the down
position.
