C. MAINTENANCE
BLADE CARE
WARNING: Before performing any main-
tenance, place the PTO switch in the
“OFF” position, engage the parking
brake, 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 already been sharp-
ened many times, or if any metal separation is present,
it is recommended that new blades be installed. New
blades are available at your authorized dealer.
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 help in breaking loose the hex nut
securing the blade (Refer to Figure 54).
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.
• Pull back the lock collar of the nozzle adapter and
push the adapter onto one of the deck wash
nozzles at either end of the mower deck. Release
the lock collar to lock the adapter on the nozzle.
See Figure 55.
