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 order.

Upper Drive Belt

Locate the transmission idler pulley on the upper drive belt by looking through the battery tray opening. See Figure 17.

Grasp the bracket and pivot the transmission idler pulley toward the rear of the tractor to release tension on the upper drive belt.

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.

Remove the upper drive belt by pulling it up through the battery tray opening.

Reroute the new upper drive belt as shown in Figure 17.
