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:
NOTE: It is recommended that both drive belts be
replaced at the same time.
• Remove the upper drive belt from around the
transmission pulley and the variable-speed pulley.
NOTE: Slowly rotate the pulley counter-clockwise to roll
the belt off it.
• Remove the upper drive belt by pulling it up through
the battery tray opening.
• Re-route the new upper drive belt as shown in
Figure 13.
Lower Drive Belt
• Remove the cutting deck as instructed earlier.
• 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 firsL
followed by the POSITIVE (red) wire. Re-install in
reverse order.
Upper Drive Belt
• Locate the transmission idler pulley on the upper
drive belt by looking through the battery tray
opening. See Figure 13.
• Grasp the bracket and pivot the transmission idler
pulley toward the rear of the tractor to release
tension on the upper drive belt.
• Remove belt from around the transmission idler
pulley.
NOTE: Proper removal of the lower drive belt requires
the removal of several tractor components. Read
through the following procedure prior to attempting it to
determine if you feel you could successfully complete it.
If you don't, see an authorized Service Dealer to have
the belt changed.
IMPORTANT: Note the routing of the lower drive belt
around both the pulleys and the belt keepers BEFORE
performing the following steps.
• Locate the variable-speed pulley through the
battery tray opening. See Figure 13.
• Remove the variable-speed pulley by loosening the
hex bolt that secures it to the transmission. Use a
second wrench to hold the hex nut on the bottom
side of the pulley.
