Changing The Deckbelt - Yard-Man 604 Operator's Manual

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.
Changing the DeckBelt
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).
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.
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 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.
