Changing the Transmission Drive Belt
All belts on your tractor are subject to wear and should
be replaced if any signs of damage are observed.
NOTE: It is recommended that both drive belts be
replaced at the same time.
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.
After disconnecting the battery cables, remove the
battery and battery tray from beneath the seat.
IMPORTANT:
When removing the battery, disconnect

by the positive (red) wire. Re-install in reverse order.

drive belt by looking through the battery tray
opening. See Figure 16.
