DECK MAINTENANCE
Cleaning And Blade Care
Use the Deck Wash System as follows:
WARNING: When using the deck wash,
never engage the deck from any position
other than the operator’s seat of the trac-
tor. Do not use an assistant or engage
deck in the presence of 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 the deck wash nozzle at the
left end of the mower deck. Release the lock collar
to lock the adapter on the nozzle. See Figure 66.
Figure 66
• Turn on the water supply.
• From the tractor operator’s seat, start the engine
and engage the PTO. Allow deck to run as
needed. Disengage the PTO and stop the engine.
• Turn off the water supply.
• Pull back the lock collar of the nozzle adapter to
disconnect the adapter from the nozzle.
• Repeat the previous steps to clean the deck
using the nozzle at the other end of the deck.
WARNING: Before performing any main-
tenance, place the PTO switch in the
“OFF” position, engage the parking
brake lever, turn the ignition key to the
“OFF” position and remove the key from
the switch. When servicing the mower
deck, be careful not to cut yourself on
the sharpened blades.
Once a month remove the hex cap screws and belt
covers to remove any accumulation of grass clip-
pings from around the spindle pulleys and V-belt.
Clean more often when mowing tall, dry grass.
The cutting blades must 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 been sharpened to within 5/8 inch of the
wind wing radius (See Figure 67), new blades must
be installed.
Figure 67
When removing the blades, use a 1-1/8 inch wrench
to hold the head of the spindle bolt while 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. See Figure 68.
Figure 68
When reinstalling the blades, be sure they are
installed so that the wind wings are pointing upward
toward the top of the deck. Tighten the nuts to 90 to
110 ft-lbs. (122 to 149 N·m).
After replacing the blades, apply grease to the
exposed threads at the bottom of the spindles to
prevent rust buildup.
