Cub Cadet ISeries - Manual (Page 29)

DRIVE SYSTEM-HYDROGEAR
23
There are two drive systems available for the I-
series tractor. One system uses two HydroGear trans-
missions. The other system uses an Infinitrak full-toroi-
dal Infinitely Variable Transmission (IVT). This chapter
will cover the HydroGear version of the tractor.
The HydroGear version of this tractor uses two
EZT transmissions. The transmission control linkages
work in unison with the steering linkage to create the
zero-turn feature. The neutral adjustments for the
transmissions and the transmission links are covered
in chapter 6A: Steering - HydroGear.
The Hydro-gear shop manual for the EZT transmis-
sions is form number BLN-52622.
Drive belt
The drive belt is the most common drive system
component that will need attention. To remove/replace
the drive belt:
1. Remove the deck as described in chapter 8:
Cutting Decks and Lift Shaft.
2. Set the parking brake.
3. Unplug the electric PTO harness.
See Figure 5A.1.

4. Unbolt the electric PTO using an impact wrench
and a 5/8” socket. See Figure 5A.2.
NOTE: If the PTO clutch will not slide off of the
crankshaft, thread the bolt half way into the
crankshaft. Make sure the belt keeper is in place
to prevent the clutch from rotating. Start the
engine and turn the PTO on and off several
times to shake it loose.
NOTE: If the PTO will not come off using the
steps above, remove the engine mounting bolts
and slide the engine back. This will give enough
clearance to slide the belt off of the engine pul-
ley.

! CAUTION ! CAUTION
Cub Cadet belts are designed to fit
our equipment and are not standard
lengths. Use of a non-OEM belt may
prevent the de-clutching mechanism from working
properly when the brakes are applied.
