CAUTION
If the cutting edge of the blade has previously been sharpened,
or if any metal separation is present, replace the blades with
new ones.
WARNING
A poorly balanced blade will cause excessive vibration, may
cause damage to the rider and/or result in personal injury.
5. Test the blade’s balance using a blade balancer.
Grind metal from the heavy side until it
balances evenly.
Note: When replacing the blade, be sure to
install the blade with the side of the blade
marked ‘‘Bottom’’ (or with a part number
stamped in it) facing the ground when the
mower is in the operating position.

Use a torque wrench to tighten the blade spindle hex flange nut
to between 70 ft-lbs and 90 ft-lbs.
Changing the Deck Belt
WARNING
Be sure to shut the engine OFF, remove the key, disconnect the
spark plug wire(s) and ground against the engine to prevent
unintended starting before removing the belt
WARNING
All belts on your lawn rider are subject to wear and should be
replaced if any signs of wear are present.
Important: The V-belt found on your rider are specially
designed to engage and disengage safely. A substitute
(non-OEM) V-belt can be dangerous by not disengaging
completely. For a proper working machine, use factory
approved belts.
To change or replace the deck belt on your rider, proceed
as follows:
1. Remove the deck. Refer to Cutting Deck
Removal on page 17.
2. Remove the belt covers by removing the hex
washer screws that fasten them to the deck. See

pulley and around the belt guard.
4. Carefully remove the deck belt from around
the two spindle pulleys and the two deck idler
pulleys. See Figure 4-18.
5. To place the new belt, begin by routing the belt
around the two outer spindle pulleys as shown
in Figure 4-18.
6. Route the belt around the two deck idler
pulleys as shown in Figure 4-18.
7. Retighten the left idler pulley hex nut loosened
in step 3.
8. Remount the belt covers removed in Step 2.
9. Re-install the deck, making sure the belt
remains routed around the pulleys as
instructed. See Figure 4-18.
10. Pull the right side of the belt, and place the
narrow V side of the belt into the PTO pulley.
11. While holding the belt and pulley together,
rotate the pulley to the left. Continue holding
and rotating the pulley and belt until the belt is
fully rolled into the PTO pulley.
