IMPORTANT:
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 foot-pounds
and 90 foot-pounds.
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. Pull the fuse out and inspect it to determine if it
is good or blown. See Figure 18.
Figure 18
WARNING:
Always use a fuse with the
same amperage capacity for replacement.
Changing the Deck Belt & PTO Belt
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:
The V-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.
• Grasp the rear most 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.
• Remove the deck belt from around all
pulleys, including the deck idler pulley.
• Route the new belts (deck belt first) as shown
in Figure 19 and Figure 20.
• Remount the belt guards removed earlier.
