CHANGING THE TRANSMISSION DRIVE BELT(S)
All belts on your tractor are subject to wear and should be replaced if any signs of cracking, shredding or
rotting 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(s) on your tractor, proceed as follows:
NOTE:
It's recommended that both drive belts be replaced at the same time.
• 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 orde_
