WARNING!: Stop the tractor engine, disengage
all PTO controls, engage the parking brake, and
wait for all movement to stop before adjusting the
deck wheels.
The cutting blades must be kept sharp at all times. Inspect and
sharpen, or replace, the cutting blades as follows:
IMPORTANT: Sharpen the cutting edges of the blades evenly so
that the blades remain balanced and the same angle of sharpness
is maintained.
• Remove the mower deck from the tractor as described earlier
in this manual. Carefully tip the deck upward to access the
bottom of the mower deck.
• To remove the blades, use a 1-1/8 inch wrench to hold the
hex head of the spindle bolt, while using a second 1-1/8 inch
wrench to loosen the hex flange nut securing the blade.
NOTE: 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 flange lock nut securing the blade.
• Inspect each blade. The cutting blades should be kept sharp
at all times.
• 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 sharpened
many times, or if any metal separation is present, it is
recommended that a new blade be installed. New blades are
available at your authorized dealer.
• When replacing the blades, be sure they are installed so that
the wind wings are pointing upward toward the top of the deck
housing. Secure the hex head of the spindle bolt and tighten
the hex flange nuts to 90 to 110 ft-lbs. (122 to 149 N·m).
• After replacing the blades, apply grease the exposed threads
at the bottom of the spindle bolts to prevent rust buildup.

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
engage the deck if bystanders are in the area.
• Attach the nozzle adapter (16) 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 the deck wash nozzle at the left end of the
mower deck. Release the lock collar to lock the adapter on
the nozzle. Refer to Figure 23.
