• Route the new belt around the three spindle pulleys.
• Pull the deck idler pulley toward the left side of the
deck and position it against the backside of the belt
as shown in Figure 27.
• Install the PTO belt and belt guards removed earlier.
• Reinstall the deck on the tractor using the removal
instructions followed in the reverse order.
Changing The Transmission 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.
Usage of a substitute (non-OEM) V-belt can create an
extremely dangerous situation by not disengaging
completely. For your safety and for a properly working
machine, use ONLY the factory approved belts.
NOTE: Replacement of the drive belt is complex. It is
strongly recommended that the procedure be performed
by a qualified mechanic with the proper tools (e.g. tractor
lift, impact tools) at your nearest Cub Cadet dealer. Read
through the following procedure prior to attempting it to
determine if you feel you could successfully complete it.
To replace the transmission drive belt proceed as follows:
• Remove the cutting deck as instructed earlier in this
section.
• Disconnect the NEGATIVE (Black) cable from the
battery and position away from the terminal.
IMPORTANT: Note the routing of the drive belt both on
the tractor and in Figure 28 BEFORE performing the
following steps.
• Locate the fixed v-idler pulley found on the left
underside of the frame. See Figure 28.
• Grasp the belt on each side of the pulley and
carefully move it toward the left frame rail, then
downward to disengage the belt fixed idler pulley.
See Figure 28.
• 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 28.
• 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.
