Operating Tips
Mowing When the Grass Is Dry
Mow either in the late morning to avoid the dew, which
causes grass clumping, or late afternoon to avoid
the damage that direct sunlight can cause on the
sensitive, freshly mowed grass.
Selecting the Proper Height-of-Cut
Setting
Remove approximately 25 mm (1 inch) or no
more than 1/3 of the grass blade when cutting. In
exceptionally lush and dense grass, you may need to
raise your height-of-cut setting.
Mowing at Correct Intervals
Grass grows at different rates at different times of
the year. To maintain the same cutting height, mow
more often in early spring. As the grass growth rate
slows in mid summer, mow less frequently. If you
cannot mow for an extended period, first mow at a
high cutting height, then mow again 2 days later at a
lower height setting.
Transporting
Use the transport latches when transporting over long
distances, rough terrain, or when trailering.
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
51).

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.

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 and transporting the
machine, if applicable.
•
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
(Figure
52).
