ADJUSTING THE GAUGE WHEELS
The cutting height of the mower deck can be set in
any of six height settings using the deck lift handle of
the tractor. The deck heights range from 1-1/2 inches
to 4 inches. The deck gauge wheel position should be
approximately 1/4 to 1/2 inch above the ground when
the deck is set in the desired height setting.
WARNING: Keep hands and feet away
from the discharge opening of the
cutting deck.
NOTE: The deck wheels are an anti-scalp feature of
the deck and are not designed to support the weight of
the cutting deck.
Using the lift handle, set the deck in the desired
height setting, then check the gauge wheel and if
necessary adjust as follows.
• With the deck set at the desired height, visually
check the distance between the gauge wheels
and the ground. If the gauge wheels are near or
touching the ground, they should be raised. If the
gauge wheels are more than 1/2" above the
ground, they should be lowered.
• Remove the lock nut securing one of the gauge
wheel shoulder screws to the deck. Remove the
gauge wheel and shoulder screw. See Figure 33.

• Insert the shoulder screw in the one of four index
holes that will give the gauge wheel a 1/4 to 1/2
inch clearance with the ground.
• Note the index hole of the just adjusted wheel;
adjust the other gauge wheel into the respective
index hole on the other side of the deck.
DECK MAINTENANCE
Cleaning the Spindle Pulleys

Mower Blade Care
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.
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 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.
The blades may be removed as follows.
• Remove the deck from beneath the tractor, (refer
to Deck Removal on page 28) then gently flip the
deck over to expose its underside.
• Use a 15/16 inch wrench to hold the hex nut on
top of the spindle assembly when loosening the
hex nut securing the blade. A block of wood may
be placed between the deck housing and the cut-
ting edge of the blade to help in breaking loose
the hex nut securing the blade. See Figure 34.

• 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
blade nuts to 70-90 ft. lbs.
• Reinstall the deck (refer to Deck Installation on
page 29).
