Mowing with Sharp Blades
A sharp blade cuts cleanly and without tearing or
shredding the grass blades like a dull blade. Tearing
and shredding causes the grass to turn brown at
the edges, which impairs growth and increases
susceptibility to diseases. Ensure that the blade is in
good condition and that there is a full sail.
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 (Figure 69).

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 the Air Conditioner
Performance
•
To limit solar heating, park the machine in a
shaded area or leave the doors open in direct sun.
•
Ensure that the air-conditioning-condenser fins
are clean.
•
Operate the air-conditioner blower at the
mid-speed setting.
•
Verify that a continuous seal exists between
the roof and the headliner. Correct the seal as
required.

2. Foam deck pad
•
Measure the air temperature at the front center
vent in the headliner.
Note:
The air temperature typically stabilizes at
less than or equal to 10°C (50°F).
•
Refer to the Service Manual for additional
information.
