Changing transaxle hydraulic fluid

NOTE: The Hydro-Gear hydrostatic transaxle
used in the Cub Cadet 1000 Series tractors typi-
cally 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.
CAUTION: The battery will be removed in this
procedure. Review the Operator's Manual and
the Electrical chapter of this manual for impor-
tant safety information about handling batteries
before proceeding.
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.
Figure 5.61
3. Locate the drain plug near the bottom of the dif-
ferential 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 it or the transaxle
may be removed from the tractor and drained
through the fill port.
