Changing theTransmission D riveBelt
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 drive belt on your tractor,
proceed as follows:
• Remove the cutting deck as instructed earlier in this
section.
• After disconnecting the battery cables, remove the
battery and battery tray from beneath the seat.
IMPORTANT: When removing the battery, disconnect
the NEGATIVE (Black) wire from it's terminal first,
followed by the POSITIVE (Red) wire. Re-install in
reverse order.

drive belt by looking through the battery tray

pulley toward the rear of the tractor to release

• Remove the belt from around the transmission idler
pulley.
• Remove the upper drive belt from around the
transmission pulley and the variable-speed pulley.
NOTE:
Slowly rotate the pulley counterclockwise to
roll the belt off of it.

the battery tray opening.
