• Pivot the double-idler bracket to relieve as much
spring tension as possible, then unhook the idler
extension spring from the screw and the idler
bracket itself. Do not misplace the spring.
• Slide the drive belt out and off of the pulleys 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. NOTE: Be careful not to lose any
washers or spacers used for installation 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.
• Remove the drive belt by feeding it from front to
rear, toward the hydrostatic transmission. See
Figure 29.
• 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.
• Install the new belt routing it EXACTLY as the old
one was routed. Refer to Figure 29.
• Install all tractor components by reversing the
previous instructions and following in the reverse
order.
IMPORTANT:
When remounting the electric PTO clutch,
make certain that it is properly oriented against the anti-
rotation bracket prior to securing it to the engine’s
crankshaft. Torque the center hex bolt to between 38
foot-pounds and 50 foot-pounds.
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.
