Changing transaxle hydraulic fluid
NOTE: The Hydro-Gear hydrostatic transaxle used in the Cub Cadet 1000 Series tractors typically lasts for
many years of homeowner use without fluid maintenance. The primary reason to change the fluid
would be contamination.
NOTE: The ambient temperature should be above 60 deg. f. (15.5 deg. C.) to allow the fluid to drain and fill in
a reasonable amount of time.
1. Allow the drive system to cool before starting work on
the tractor.
2. Remove the battery and battery tray by following the
procedures described in Chapter 4: Body Panels.
See Figure 5.61.
3. Locate the drain plug near the bottom of the differen-
tial housing of the transaxle.
4. Clean the area around the drain plug, and place a
drain pan of at least 1 gallon (4 liters) capacity under
the transaxle.
5. Remove the plug using a 1/4” allen wrench, and allow
the fluid to drain.
NOTE: If the transaxle does not have a drain plug:
• The fluid may be siphoned out or the transaxle
may be removed from the tractor and drained
through the fill port.
6. Locate the fill port. It is the socket-head cap plug on
top of the transaxle casting. It is not the black cap on
top of the plastic catch tank.
7. Clean the area around the fill port.
8. Remove the plug using a 1/4” allen wrench.
See Figure 5.62.
NOTE: If the transaxle is draining slowly, this will allow
more air to enter the housing, speeding up the
draining process.
9. After the transaxle has drained completely, reinstall
the drain plug.
! CAUTION ! CAUTION
The battery will be removed in this procedure. Review the Operator’s Manual and Chapter 7:
Electrical System for important safety information about handling batteries before proceeding.
