NOTE: An air/impact wrench is needed to remove the
electric PTO and properly replace the drive belt.
All belts on your tractor are subject to wear and should
be replaced if any signs of wear are present.
IMPORTANT: The V-belts found on your tractor are
specially designed to engage and disengage safely. A
substitute (non-OEM) V-belt can be dangerous by not
disengaging completely. For a proper working machine,
use factory approved belts.
To change or replace the drive belt on your tractor,
proceed as follows:
• Remove the cutting deck as instructed earlier in this
• After disconnecting the battery cables, remove the
battery and battery tray from beneath the seat.
IMPORTANT: When removing the battery, disconnect
the NEGATIVE (Black) wire from it’s terminal first,
followed by the POSITIVE (Red) wire. Re-install in
IMPORTANT: Note the routing of the lower drive belt
around all the pulleys and the belt keepers (if present)
BEFORE performing the following steps.
• Locate the fixed v-idler pulley found on the left
underside of the frame. See Figure 20.
• Grasp the belt on both sides of the pulley and
gently move it toward the left frame rail allowing it to
unseat itself from the fixed v-idler. See Figure 20.
• Pivot the double-idler bracket forward slightly
before removing the idler extension spring from the
stud and the double-idler bracket itself. Do NOT
discard the spring.
• Roll the drive belt out from around both the v-idler
pulley and the flat idler pulley found on the doubleidler
• 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
• Be careful not to lose any washers or spacers which may be found on top of the electric PTO
The following most likley will not work as the pulley is rusted to the shaft
and will not move. Forget pullers they won't fit.
(• 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.)
• What worked for me and took about an hour was to remove 4 engine bolts and 4 muffler bolts
this alows the engine to slide towards the back of the mower giving you room to place the drive
belt around the pulley. Oh 1 more thing you're replacing the belt - Cut off the old one.
IMPORTANT: When remounting the electric PTO clutch,
make certain that is properly oriented against the antirotation
bracke prior to securing it to the engine’s
crankshaft. Torque the center hex bolt to between 38
foot-pounds and 50 foot-pounds.
• Remove the drive belt by feeding it from front to
rear, toward the hydrostatic transmission. See
• Continue removing the drive belt by gently lifting it
off of the transmission pulley and over the cooling
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
• Reroute the new belt around the pulleys and belt
keepers, if present, EXACTLY as the old one was
