• 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.

• Remove the hex bolt from the center of the
electric PTO clutch and gently lower the
electric PTO clutch off of the engine
crankshaft. 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.
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.
• Reroute the new belt around the pulleys and
belt keepers 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 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

• Remove the drive pedal return spring.
• Using two 9/16" wrenches, remove the pin
from the speed control assembly. See Figure
19.
