PTO belt
The function of the PTO belt is to transfer the mechanical force from the engine to the blades. The PTO belt
encounters many different forces:
• The friction of the belt grabbing the different pulleys creates heat. This heat softens the belt which weak-
ens 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 electric 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. This 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.
To replace the PTO belt:
1. Remove the deck as described at the beginning of
this chapter.
NOTE: Removal of the deck is necessary because of the
belt guides built into the belt covers.
2. Remove the belt covers.
3. Slide the belt off of the pulleys.
NOTE: Some decks have belt guides on the idler pulleys.
Loosen the nut and bolt that secure the idler pulley
enough so that the PTO can slip out from in
between the guide and the pulley.
See Figure 8.15.
! CAUTION ! 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 or stopping properly.
