Figure 14
Front to Rear Levelling
• Place the deck in the highest position.
• Wearing a pair of heavy work gloves to prevent
injury, rotate the cutting blade so that it is pointed
front to back and parallel to the rider. Depress and
lock the deck engagement pedal.
• Completely loosen, but do not remove, the top hex
nut out of the three hex nuts that hold the hex bolt
and the ferrule on the deck hanger link assembly.
See Figure 14 .
IMPORTANT: Do not try to loosen/ tighten bottom nut.
• Thread the middle nut as far down as possible.
• Keeping an equal number of threads above each of
the nuts, thread the upper nut down until the front
tip of the blade is 1/4” to 3/8” lower than the rear tip
of the blade. Note that threading this nut down will
raise the front of the deck.
• Thread the middle nut up against the base of the
ferrule. See Figure 14 .
• Tighten the upper nut against the top of the ferrule
to lock adjustment.
Side to Side Levelling
• Place the deck in the highest position.
• Wearing heavy work gloves to prevent injury, rotate
the cutting blade so that it is pointed side to side
and perpendicular to the rider. Depress and lock
the deck engagement pedal.
• Loosen the middle hex nut.
• Thread the top hex nut up or down in order to set
both tips of the blade at an equal height from the
ground. Remember to thread the nut down to raise
the deck, and thread up to lower the deck.
• Once the deck is level, thread the middle hex nut to
tighten against the ferrule. Make sure the cut is
even and the lift lever moves to all cutting heights.
SECTION 7: SERVICING YOUR RIDER MOWER
Belt Replacement
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.
Deck Belt
• Engage the parking brake and turn the ignition off.
Pivot the seat frame up and remove the
grasscatcher. 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 9/16” wrench, loosen the hex nut on the
idler pulley. See Figure 15.
• 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 will have to work from the top left side of
the mower. Remove the cover.
