3. Reinstall drain plugs.
4. Remove the oil reservoir hose attached to the
elbow on top of the transaxles and remove the
elbows to access the oil ll openings.
5. Fill the transaxles with 20W-50 (API Service
Class SL or higher) oil through the opening
where the elbows were. Fill up to the opening.
6. Before reinstalling the elbows, screw the lock-
ing nut on the elbows down until they are snug

7. Reinstall the elbows. When the elbow begins to
be snug, position the elbow as it was when re-
moved and tighten the locknut. Reinstall reser-
voir hoses to elbows.
8. Fill reservoir to 1/4-1/2 in. (6-13 mm) with
20W-50 (API Service Class SL or higher) oil.
9. Start and drive the unit for 1 - 2 minutes.
10. If the transaxle sounds noisy or has poor steer-
ing response, there may be air trapped in the
transaxle. Follow purge instructions below.
11. To purge air from transaxle, raise unit and block
with tires off the ground. With engine running,
slowly move Forward Speed Control forward
and backward 5 to 6 times. Turn off engine and
check oil level and add if needed. Repeat pro-
cedure until transaxle operate at normal noise
levels and move smoothly in forward and re-
verse.
Grease Fitting and Oil Point Lubrication
Lubricate the grease ttings and oil points after ev ery
25 hours of operation. Lubricate more often when
operating in dusty or dirty conditions. Use SAE
general purpose lithium or molybdenum base grease
for grease ttings and light machine oil (SAE 10) to
lubricate oil points. Lubricate the locations shown
in the Chassis and Deck Lubrication Points
illustration.
NOTE: PTO universal joints (on the deck and trac-
tor) require routine lubrication after every 8 hours
of running time.
NOTE: The best way to lubricate the PTO tube half
of the universal joint assembly is to remove it from
the tractor. See instructions for removing and install-
ing PTO quick coupler, refer to Deck Installation in
Mower Deck Installation on Tractor in the Assem-
bly Instructions.
