Remove the hex bolt from the center of the engine 
pulley 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 engine 
pulley.
IMPORTANT:
 When remounting the engine pulley (or 
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. 
Route the replacement belt around the pulleys, belt 
keepers and keeper pins EXACTLY as the old one 
was routed. Refer to Figure 16.
The drive pedal 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 drive pedal. See Figure 17.

Adjust the drive pedal after replacing the drive belts on 
your tractor, if necessary, as follows:
Locate the speed control assembly on the 
underside of the steering support bracket. See 
Figure 18.
Remove both hairpin clips from the pin which is 
fastened to the speed control assembly (be careful 
not to lose the small flat washers found on the pin). 
See Figure 18.
Remove the drive pedal return spring.
Figure 18
Using two 9/16" wrenches, remove the pin from the 
speed control assembly. See Figure 18.
Thread the idler adjustment rod inward or outward to 
lengthen or shorten the travel of the double-idler 
bracket until proper adjustment is achieved.
Reassemble by following the above steps in 
reverse order. 
Tires
WARNING: 
Never exceed the maximum
inflation pressure shown on the sidewall of the
tire.
The recommended operating tire pressure is 
approximately 10 psi for the rear tires and 
approximately 14 psi for the front tires. Refer to the tire 
sidewall for exact tire manufacturer’s recommended or 
maximum psi. Do not overinflate. Uneven tire pressure 
could cause the cutting deck to mow unevenly.
