6. When aligned, push each pin fully
inward through the lift arms to secure
the arms in the rear hanger bracket slots.
7. Make certain the 'V' belt is in the spindle
pulleys on the deck; then route the belt
rearward beneath the tractor frame,
above the transmission tube(s), to the
PTO pulley on the bottom of the engine.
8. Using the deck lift handle, raise the deck
to the position that provides the most
horizontal run of the belt between the
deck idler pulleys and the PTO pulley on
the bottom of the engine.
9. Make certain the belt is in the spindle
pulleys of the deck, and that the
backside of the belt is against both the
fixed and movable idler pulleys.
10. Sitting behind the tractor, facing forward,
make certain the belt is not twisted; then
reach beneath the tractor to grasp the
belt and pull it toward the PTO pulley.
WARNING! Use caution to avoid
pinching your fingers when
rolling the belt onto the PTO
pulley.
11. Pull the right side of the belt rearward
and place the narrow V side of the belt
into the PTO pulley. See Figure 4-18.
12. While holding the belt and pulley
together, rotate the pulley to the left
(See Figure 4-18). Continue holding and
rotating the pulley and belt until the belt is
fully rolled into the PTO pulley.
NOTE: Before using the tractor double-
check the belt routing to make sure that
the belt has been routed properly.

pulleys.
5. Install the new belt around the spindle
pulleys as shown and reinstall the belt
covers. See Figure 4-22.

Mower Blade Care
WARNING! Before performing
any maintenance, place the PTO
switch in the "OFF" position,
engage the parking brake lever,
turn the ignition key to the "OFF"
position and remove the key from
the switch. Protect your hands by
using heavy gloves when handling
the blades. When servicing the
mower deck, be careful not to cut
yourself on the sharpened blades.
The cutting blades must be kept sharp at all
times. Sharpen the cutting edges of the blades
evenly so that the blades remain balanced and
the same angle of sharpness is maintained.
If the cutting edge of a blade has already been
sharpened many times, or if any metal separation
is present, it is recommended that new blades
be installed. New blades are available at your
authorized dealer.
The blades may be removed as follows.
1. Remove the deck from beneath the tractor,
(refer to "Deck Removal" on page 23)
then gently flip the deck over to expose its
underside.
2. Use a 1-1/8" wrench to hold the hex nut
on top of the spindle assembly when
loosening the bolt securing the blade. A
block of wood may be placed between the
deck housing and the cutting edge of the
blade to help in breaking loose the hex nut
securing the blade. See Figure 4-23.
Figure 4-23
3. When reinstalling the blades, be sure they
are installed so that the wings are pointing
upward toward the top of the deck.
4. Tighten the blade nuts to 70-90 ft. lbs.
5. Reinstall the deck. Refer to "Deck
Installation" on page 23.
Changing the Transmission Drive Belt
Several components must be removed and
special tools used in order to change the tractor's
transmission drive belt. See your Cub Cadet dealer
to have the transmission drive belt replaced.
Tractor Creeping
Creeping is the slight forward or backward
movement of the mower when the throttle
is on and the speed control levers are in the
neutral position. If your mower creeps, see an
authorized service dealer.
