Operating Tips

Selecting the Proper Height-of-Cut
Setting
Remove approximately 25 mm (1 inch) or no more
than a third of the grass blade when mowing. In
exceptionally lush and dense grass, you may need to
raise the height-of-cut to the next setting
Figure 74
Mowing When Grass Is Dry
Mow either in the late morning to avoid the dew, which
causes grass clumping, or in late afternoon to avoid
the damage that direct sunlight can do to sensitive,
freshly-mowed grass.
Mowing at the Proper Intervals
Under most normal conditions, you will need to mow
approximately every 4 to 5 days. But, grass grows
at different rates at different times. So, to maintain
the same height of cut (which is a good practice), you
will need to cut more frequently in the early spring; as
the grass growth rate slows in mid summer, cut only
every 8 to 10 days. If you are unable to mow for an
extended period due to weather conditions or other
reasons, mow first with a high height of cut; then mow
again 2 to 3 days later with a lower height setting.
Adjusting the Mower-Deck Pitch
Mower-deck pitch is the difference in height-of-cut
from the front of the blade plane to the back of the
blade plane. Use a blade pitch of 7.6 mm (0.3 inch).
A pitch larger than 7.6 mm (0.3 inch) results in less
power required, larger clippings, and a poorer quality
of cut. A pitch less than 7.6 mm (0.3 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 screen is clean.
•
Ensure that the air-conditioning-condenser fins
are clean.
•
Operate the air-conditioner blower at the
mid-speed setting.
•
Ensure that there is a continuous seal between the
roof and the headliner and correct it as needed.
(Figure 74).
•
Measure the air temperature at the front, center
vent in the headliner. This should typically stabilize
at less than or equal to 10° C (50° F).
•
Refer to the Service Manual for additional
information.
