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.
IMPORTANT: Use a torque wrench to tighten the blade
spindle hex flange nut to between 70 foot-pounds and
90 foot-po unds.
Fuses
Two fuses are installed in your tractor's wiring harness
to protect the tractor's electrical system from damage
caused by excessive amperage.
If the electrical system does not function, or your
tractor's engine will not crank, first check to be certain
that the fuse has not blown.
One can be found under the hood mounted behind the
top of the dash panel on the support bar.
The other can be found under the seat mounted to the
inside of the tractor frame next to the battery tray.
_, ARNING: Always use a fuse with the
same amperage capacity for replacement.
ChangingtheDeckBelt& PT0Belt
WARNING: Be sure to shut the engine off,
remove ignition key, disconnect the spark
plug wire(s) and ground against the engine to
prevent unintended starting before removing
the belt(s).
All belts on your tractor are subject to wear and should
be replaced if any signs of wear are present.
IMPORTANT:TheV-belts found on your tractor 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 and PTO belt on
your tractor, proceed as follows:
• Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
• Remove the belt guards by removing the self-
tapping screws that fasten them to the deck.
46-inch Decks
• Grasp the rearmost portion of the PTO idler bracket
and pivot it toward the discharge chute to relieve
tension on the PTO belt.
• Remove the PTO belt from around the engine
pulley (or electric PTO clutch) and from around the
PTO idler pulley(s).
• Grasp the deck idler pulley and pivot it toward the
left to relieve tension on the deck belt.
50-inchDecks
• To ease in removing the belt in later steps, loosen,
but do not remove, the bolt which secures the
pivoting idler pulley to the idler bracket.
See Figure 19.
Belt Guard
Figure 19
• Insert a 3/8"-drive ratchet wrench (set to tighten)
into the square hole found in the idler bracket on
the left side of the deck's surface. See Figure 19.
• Grasp the ratchet's handle and pivot it toward the
tractor's right side to relieve tension on the belt.
• With belt tension relieved, carefully remove the
belt from around the left-hand spindle pulley.
WARNING: Avoid the possibility of a
pinching injury. Do not place your fingers on
the idler spring or between the belt and a
pulley while removing the belt.
IMPORTANT:Carefully allow the ratchet to pivot
rearward before removing it from the square hole.
All Models
• Remove the deck belt from around all pulleys,
including the deck idler pulley.
• Route the new belts (deck belt first) as shown in
and Figure 20.
• Remount the belt guards removed earlier.
