IMPORTANT:

 Note the routing of the lower drive belt 

around both the pulleys and the belt keepers BEFORE 
performing the following steps. 

•

Unthread the shift lever knob and unfasten the 
plastic tray from the fender by removing the four 
screws which secure it.

•

Locate the variable-speed pulley through the 
battery tray opening. See Figure 16.

•

Remove the variable-speed pulley by loosening the 
hex bolt that secures it to the transmission. Use a 
second wrench to hold the hex nut on the bottom 
side of the pulley.

•

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

•

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

•

Remove the hex bolt from the center of the electric 
PTO clutch and gently lower it off of 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 and through the shifter tray hole in the front 
of the fender.

•

Reassemble by following the above steps in 
reverse order. 

•

Reroute the new 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 17.

•

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 17.

•

Remove the drive pedal return spring.
