8. Using the deck lift handle, raise the deck to the position that
provides the most horizontal run of the belt between the deck
idler pulleys and the PTO pulley on the bottom of the engine.
9. Make certain the belt is in the spindle pulleys of the deck,
and that the backside of the belt is against both the fixed and
movable idler pulleys.
10. Sitting behind the tractor, facing forward, make certain the
belt is not twisted; then reach beneath the tractor to grasp the
belt and pull it toward the PTO pulley.
WARNING: Use caution to avoid pinching your fingers when
rolling the belt onto the PTO pulley.
11. Pull the right side of the belt rearward and place the nar-
row V side of the belt into the PTO pulley. See Figure 30.
12. While holding the belt and pulley together, rotate the pul-
ley to the left (See Figure 30). Continue holding and rotating
the pulley and belt until the belt is fully rolled into the PTO
pulley.
NOTE: Before using the tractor double-check the belt routing
to make sure that the belt has been routed properly.
REPLACING THE BELT
1. Remove the deck from be-
neath the tractor, (refer to Deck
Removal section).
2. Remove the hex washer
screws securing the belt covers
to the deck. See Figure 33.
3. Remove the two idler pul-
leys by removing the hex screws
and flange lock nuts that se-
cure them to the deck and the
idler arm. See Figure 34. Do not
lose any of the hardware when
removing the hex screw and
flange lock nut.
NOTE: Take note of the position
of the belt guards to ensure they
are properly re-installed.
4. Remove the belt from the
spindle pulleys.
5. Install the new belt around
the spindle pulleys as shown and
reinstall the belt covers. See Fig-
ure 33.
6. Place the belt around the idler pulleys removed in step 3 with
the "V" side facing in. Once in place, reinstall all the hardware
and tighten the flange lock nut to secure the assembly. See Fig-
ure 34.
7. Route the belt as shown in Figure 33 and then reinstall the
deck (refer to Deck Installation section).

MOWER BLADE CARE
WARNING: Before performing any maintenance, place the
PTO switch in the "OFF" position, engage the parking brake le-
ver, turn the ignition key to the "OFF" position and remove the
key from the switch. Protect your hands by using heavy gloves
when handling the blades. 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 sharpened 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:
1. Remove the deck from beneath the tractor, (refer to Deck
Removal, section) then gently flip the deck over to expose its
underside.
2. Use a 15⁄16" wrench to hold
the hex nut on top of the spin-
dle assembly 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. See Fig-
ure 35.
3. When reinstalling the blades, be sure they are installed so
that the wings are pointing upward toward the top of the deck.
4. Tighten the blade nuts to 70-90 ft. lbs.
5. Reinstall the deck (refer to Deck Installation, section).
CHANGING THE TRANSMISSION DRIVE BELT
Several components must be removed and special tools used in
order to change the tractor's transmission drive belt. See your
authorized service dealer to have the transmission drive belt
replaced.
TRACTOR CREEPING
Creeping is the slight forward or backward movement of the
mower when the throttle is on and the speed control levers are
in the neutral position. If your mower creeps, see an authorized
service dealer.
