Changing the Transmission Drive Belt

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 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 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 16.

• 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.
