ChangingTheTransmissionDriveBelt
NOTE: 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 your drive belt replaced.
HydrostaticTransmission
Keep the area around the transmission cooling fan free
of grass and debris at all times. The hydrostatic
transmission is sealed at the factory and is
maintenance free. The fluid level cannot be checked
and on most models, cannot be changed.
IMPORTANT:Several tractor components and parts
(pedals, seat, fender, fuel tank, etc.) must be removed
in order to refill the transmission after draining it.
If your tractor is equipped with a transmission drain plug
(see Figure 21 ), exposed to extreme conditions (hilly
terrain, towing, etc.) and you choose to change the
hydrostatic fluid, do so after the tractor's initial 50 hours
of operation and once a season thereafter.
Drain Plug
NOTE: View shown from beneath tractor,
Figure 21
After draining the oil, refill the transmission with 76 oz.
(to the top of the fill hole found on the transmission's
surface) with any SAE 20W50 motor oil.

,_ WARNING: Be sure to shut the engine off
and remove the ignition key, to prevent
unintended starting.
WARNING: Avoid the possibility of a
pinching injury. Do not place your fingers on
the idler spring or between the belt and a
pulley while removing the 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 deck belt on your tractor,
proceed as follows:
• Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
• Remove the belt guards by removing the self-
tapping screws that fasten them to the deck.

electric PTO clutch.
• Remove the cutting deck as instructed earlier in this
section.
