After Operating
To ensure optimum performance, clean the underside of the
mower housing after each use. If residue builds up in the
mower housing, cutting performance decreases.
Also, remove any debris which may have collected between
the deck-lift cylinders and the foam-deck pads

Mower Deck Pitch
A blade pitch of 8 to 11 mm (5/16 to 7/16 inch) is
recommended. A pitch larger than 8 to 11 mm (5/16 to 7/16
inch) results in less power required, larger clippings, and a
poorer quality of cut. A pitch less than 8 to 11 mm (5/16 to
7/16 inch) results in more power required, smaller clippings
and a better quality of cut.
Maximizing Air Conditioner
Performance
•
To limit solar heating, park the machine in a shaded area
or leave the doors open in direct sun.
•
Check to make sure the air conditioning condenser fins
are clean.
•
Operate the air conditioner blower at the mid speed
setting.
•
Verify continuous seal between the roof and the headliner;
correct as required.
•
Measure the air temperature at the front center vent in
the headliner (Typically stabilize at less than or equal to
50 degrees F.)
•
Refer to the Service Manual for additional information.
(Figure
31).

After Operation Safety
General Safety
•
Clean grass and debris from the cutting units, drives,
mufflers, and engine to help prevent fires. Clean up oil
or fuel spills.
•
Shut off the fuel while storing or transporting the
machine.
•
Disengage the drive to the attachment whenever you are
transporting or not using the machine.
•
Allow the engine to cool before storing the machine in
any enclosure.
•
Never store the machine or fuel container where there is
an open flame, spark, or pilot light, such as on a water
heater or on other appliances.
Pushing or Towing the
Machine
In an emergency, the machine can be moved forward by
actuating the bypass valve in the variable-displacement
hydraulic pump and pushing or towing the machine.
Important: Do not push or tow the machine faster than 3
to 4.8 km/h (2 to 3 mph), because internal-transmission
damage may occur. The bypass valves must be open
whenever the machine is pushed or towed.
1. Raise the seat and locate the bypass valves, which are
located below the front of the fuel tank

2. Rotate each valve 3 turns counter-clockwise to open
and allow oil to bypass internally.
