the mower with the discharge deflector raised, removed, or altered
unless a grass collection system or mulch
kit is in place and working properly.
-
Park the
machine on a level surface, disengage the blade-control switch, and
move the motion-control levers outward to the
Park position.

Cleaning
Washing the Underside of the Mower
Deck
You can wash the machine with
a mild detergent and water. Do not pressure wash the machine. Avoid
excessive use of water, especially near
the control panel, under the seat, around the engine, hydraulic pumps,
and motors.
Wash the underside of the mower
deck after each use to prevent grass buildup for improved mulch action
and clipping dispersal.

machine on a level surface, disengage the blade-control switch (PTO),
and move the motion-control levers outward
to the Park position.
-
Shut off
the engine, remove the key, and wait for all moving parts to stop
before leaving the operating position.
-
Attach a
hose to the hose coupling 
, then attach the hose coupling
to the end of the mower washout fitting and turn the water on high.
Note: Spread petroleum jelly on the washout fitting O-ring to make the coupling slide on
easier and protect the O-ring.
-
Sit on the
seat, lower the mower to the lowest height-of-cut, and start the engine.
-
Engage the
blade-control switch and let the mower run for 1 to 3 minutes.
-
Disengage
the blade-control switch, shut off the engine, remove the key, and
wait for all moving parts to stop.
-
Turn the
water off and remove the coupling from the washout fitting.
Note: If the mower is not clean after 1 washing, soak it and let it stand
for 30 minutes. Then repeat the process.
-
Run the mower
again for 1 to 3 minutes to remove excess water.
|
Warning |
|
A
broken or missing washout fitting could expose you and others to thrown
objects or blade contact. Contact with a blade or
thrown debris can cause injury or death.
- Replace broken or missing washout
fitting immediately, before using machine again.
- Never put your hands or feet under
the mower or through openings in the machine.
