Pivot the double-idler bracket forward slightly before removing the idler extension spring from the stud and the double-idler bracket itself. Do NOT discard the spring.

Roll the drive belt out from around both the v-idler pulley and the flat idler pulley found on the double- idler bracket.

Carefully unplug the tractor’s wire harness from the connector on the electric PTO clutch.

Note the orientation of the electric PTO clutch. Remove the hex bolt from the center of the electric PTO clutch and gently lower it off of the engine crankshaft.

Be careful not to lose any washers or spacers which may be found on top of the electric PTO clutch.

The engine pulley is located directly above the electric PTO clutch. Lower the engine pulley far enough to be able to remove the upper drive belt from around it..

IMPORTANT: When remounting the electric PTO clutch, make certain that is properly oriented against the anti- rotation bracke prior to securing it to the engine’s crankshaft. Torque the center hex bolt to between 38 foot-pounds and 50 foot-pounds.

Remove the drive belt by feeding it from front to rear, toward the hydrostatic transmission. See Figure 20.

Continue removing the drive belt by gently lifting it off of the transmission pulley and over the cooling fan.

IMPORTANT: The fins on the cooling fan are only slightly flexible. Be careful not to damage the fan when removing the drive belt from around the transmission pulley.

Reroute the new belt around the pulleys and belt keepers, if present, EXACTLY as the old one was routed. Refer to Figure 20.

Hydrostatic Transmission

The hydrostatic transmission is sealed at the factory and is maintenance free. The fluid level cannot be checked nor can the oil be changed. Always keep the area around the transmission cooling fan free of grass and debris at all times.
