CUTTING HEIGHT ADJUSTMENT
The mower can be set in multiple positions. NOTE: If
multiple settings are used while mowing, it may be
necessary to adjust the gauge wheels for each setting
to prevent scalping.
1. Push, or pull, the tractor implement lift handle to
depress the button on top of the lift handle.
2. Raise or lower the lift handle to obtain the desired
mower deck cutting height.
3. Release the button when the desired mower
position is obtained. Note the numbered position of
the lift lever indicator so that the deck can be
returned to this position.
C. MAINTENANCE
BLADE CARE
WARNING
Before performing any maintenance, place the
PTO switch in the “OFF” position, engage the
brake pedal lock, turn the ignition key to the
“OFF” position and remove the key from the
switch to avoid accidental starting and injury.
When servicing the mower deck, be careful not
to cut yourself on the sharpened blades.
The cutting blades must be kept sharp at all times.
IMPORTANT: Sharpen the cutting edges of the blades
evenly so that the blades remain balanced and the
same angle of sharpness is maintained.
If the cutting edge of a blade has been sharpened to
within 5/8 inch of the wind wing radius (See Figure 55),
it is recommended that new blades be installed. New
blades are available at your authorized dealer.
Figure 55
When removing the blades, use a 1-1/8 inch wrench to
hold the hex head of the spindle bolt when loosening
the hex nut securing the blade. A block of wood may
be placed between the deck housing and the cutting
edge of the blade to assist in removal of the hex nut se-
curing the blade (Refer to Figure 56).
After replacing the blades, apply grease the exposed
threads at the bottom of the spindle bolts to prevent
rust buildup.
When replacing the blades, be sure they are installed
so that the wind wings are pointing upward toward the
top of the deck housing. Tighten the nuts to 90 to 110
ft-lbs. (122 to 149 N·m).

CLEANING THE MOWER DECK
Using The Deck Wash System
WARNING: When using the deck wash
system, never engage the deck from any
position other than the operator’s seat of
the tractor. Do not use an assistant or
engage deck in the presence of any
bystanders.
• Attach the nozzle adapter to a standard garden
hose connected to a water supply.
• Move the tractor to an area within reach of the
hose where the dispersal of wet grass clippings is
not objectionable to you. Disengage the PTO,
engage the parking brake, and stop the engine.
