SECTION 7: SERVICING YOUR RIDER MOWER
BeltReplacement
There are two drive belts and one deck belt in your rider
mower; follow the description below to identify the belts.
1. The lower drive belt goes from the variable speed
pulley to the transmission pulley.
2. The upper drive belt goes from the variable speed
pulley to the upper sheave of engine pulley.
3. The deck belt goes from the deck pulley to the
lower sheave in engine pulley.
Periodically check to see if these belts are too loose
or damaged through wear and tear. If so, replace
with new belt.
DeckBelt
Engage the parking brake and turn the ignition off.
Pivot the hood assembly up and remove the grass
catcher. Remove the spark plug wire.
Put the deck at the lowest cutting height by
adjusting the cutting height adjustment lever to the
lowest position.
Using a 1/2" socket wrench, remove two self-
tapping screws, lock washer and hex nut that hold
the deck belt cover to the deck. See Figure 15. For
this, you wilt have to work from the top left side of
the mower. Remove the belt cover.
