Transaxle Oil and Filter Change
Change the transaxle oil after the initial break-in
period of 75-100 hours. Thereafter, change oil ev-
ery 400 hours of operation as follows:
1. Thoroughly clean the exterior of the transaxle
housing before servicing. Remove expansion
reservoir cap to allow venting. Remove the
blower receiver cone by removing the four (4)
1/4-20 x 3/4 hex bolts for access to transaxle oil
drain plugs. Using a 1/4 in. hex wrench, remove
the plug on the lower inside of each transaxle
allowing the oil to drain.
2. Remove the oil lter guard, remove and replace
the oil lter using an oil lter wrench. Tighten
lter by turning lter 3/4 to 1 turn after gasket
contacts the lter base surface. Reinstall the oil
lter guard. (Refer to Transaxle Oil Drain
Plug, Filter, and Guard Location illustration.)

3. Reinstall drain plugs.
4. Remove the oil reservoir hose attached to the
elbow on top of the transaxles. Remove the
elbows to access the oil ll opening.
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
(the o-ring on the elbow will be to the bottom of
the o-ring groove).

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 transaxles sound noisy or have poor steer-
ing response, there may be air trapped in the
transaxles. Follow purge instructions below.
11. If oil needs to be added, refer back to steps
4-10.
12. To purge air from transaxle, raise tractor and
block with tires o the ground. With engine run-
ning, slowly move Forward Speed Control for-
ward and backward 5 to 6 times. Turn o en-
gine and check oil level and add if needed.
Repeat procedure until transaxles operate at
normal noise levels and move smoothly in for-
ward and reverse.
