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 transmis-
sion housing before servicing. Remove expan-
sion tank cap to allow venting. Using a 1/4 in.
hex wrench, remove the plug on the lower in-
side 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. Fill the transaxles with 20W-50 (API Service
Class SL or higher) oil through the reservoir. Fill
up to the opening.
5. Fill both reservoirs to a maximum oil level of
1/4 in. (6.35 mm) with 20W-50 (API Service
Class SL or higher) oil.
6. Start and drive the unit for 1 - 2 minutes.
7. If the transaxles sound noisy or have poor steer-
ing response, there may be air trapped in the
transaxles. Follow purge instructions below.
8. If oil needs to be added refer back to steps 4-7.
9. 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 operates at normal noise
levels and move smoothly in forward and re-
verse.
