Page 25

•Grasp the ratchet’s handle and pivot it toward the front of the tractor to relieve tension on the belt.

•With belt tension relieved, carefully remove the belt from around the left-hand spindle pulley.

IMPORTANT: Carefully allow the ratchet to pivot rearward before removing it from the square hole.

•Remove the deck belt from around all pulleys, including the deck idler pulley.

•Route the new belts (deck belt first). See Figure 21IMPORTANT:.

•Remount the belt guards removed earlier.

CHANGING THE TRANSMISSION DRIVE BELTS

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.

All belts on your tractor are subject to wear and should be replaced if any signs of wear are present.

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 in this section.

•After disconnecting the battery cables, remove the battery and battery tray from beneath the seat.

NOTE: 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. Proper removal of the 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 your authorized dealer to have the belt changed.

IMPORTANT: Note the routing of the lower drive belt around all the pulleys and the belt keepers (if present) BEFORE performing the following steps.

Upper Drive Belt

Locate the transmission idler pulley on the upper drive belt by looking through the battery tray opening. See Figure 22.

•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.
