•Reassemble by following the above steps in reverse order.

Slide the belt off of the variable-speed pulley as you lift the pulley up and out through the battery tray opening.

NOTE: Jacking the rear of the tractor up off the ground and securing it with jackstands at this point in the procedure will ease the following steps, but is not necessary.

Remove the rear idler pulley from the double- idler bracket while unrouting the belt from around both the rear and the front idler pulley. Refer to Figure 16.

Carefully unplug the tractor’s wire harness from the connector on the electric PTO clutch. See Figure 17.

Figure 17

Remove the hex bolt from the center of the electric PTO clutch and gently lower the electric PTO clutch off of the engine crankshaft. Be careful not to lose the flat washer found on top of the electric PTO clutch. See Figure 17.

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. Be careful not to lose the 1/4-inch square key which acts as a guide for the pulley on the engine crankshaft.

IMPORTANT: When remounting the electric PTO clutch, torque the center hex bolt to between 38 foot-pounds and 50 foot-pounds.

Remove the drive belt by feeding it from both ends toward the front idler pulley on the double-idler bracket. See Figure 16.

Reassemble by following the above steps in reverse order.

IMPORTANT: When remounting the electric PTO clutch, make certain that the stud found to the right of the engine crankshaft slides up through the hole found in the top of the electric PTO clutch.

Reroute the new belt around the pulleys and belt keepers EXACTLY as the old one was routed. Refer to Figure 16.

The AutoDrivepedal is properly adjusted when the hole found in the double-idler bracket has approximately 1-3/8" of travel with ten pounds of pressure applied to the AutoDrivepedal. See Figure 18.
