3. Remove the spindle covers.
4. Slip the PTO belt off of the spindle pulley that is
to be serviced.

the deck. See Figure 8.13.

PTO belt
The function of the PTO belt is to transfer the mechani-
cal force from the engine to the blades. The belt faces
alot of different forces.
• The friction of the belt grabbing the different pul-
leys creates heat. This heat softens the belt
which weakens it.
• Every time the electric PTO is engaged, the PTO
belt is subjected to an impact load. When the
electric PTO is engaged, it goes from 0 to 3,600
RPM instantly. This can actual remove sections
of the belt.
NOTE: Engaging the Electric PTO before the
mowing deck is placed into the grass will reduce
the impact load on the belt.
• When a blade impacts an object like a rock or a
tree root, the belt is subjected to an impact load
similar to the impact load of engaging the elec-
tric PTO.
• The belt has rubber in it. As the rubber ages, it
becomes brittle making it weaker.
NOTE: A damaged belt can cause the deck to
vibrate when the deck is engaged. The vibration
can be bad enough to simulate an engine issue.
NOTE: Not all belt damage is visible. Broken
cords inside the belt are not visible to the naked
eye, but can cause vibration issues and greatly
reduce the life of the belt.
CAUTION: Cub Cadet belts are design to fit our
equipment and are not standard lengths. Use of
a non-OEM belt may prevent the mowing deck
from working properly.
To replace the PTO belt:
1. Remove the deck as describe at the begining of
this chapter.
NOTE: Removal of the deck is necessary
because of the belt guides built into the belt cov-
ers.
2. Remove the belt covers.
