Check Transaxle Fluid Level
● The transaxle oil lubrication is SAE 20W-50
(API Service Class SL or higher) engine oil.
● Inspect both transaxle cases and hoses
after
every 25 hours
of operation for visible leaks.
● The fluid level of the transaxles can be
checked visually by looking at the fluid level in
the expansion reservoir. When the transaxles
are cold, the fluid level in the expansion reser-
voir should be between 1/4 in. and 1/2 in. (0.64
cm and 1.27 cm).

Transaxle Oil and Filter Change
Change the transaxle oil after the initial
break-in
period of 75-100 hours
. Thereafter,
change oil
every 400 hours
of operation as follows:
1. Thoroughly clean the exterior of the transaxle
housing before servicing. Remove expansion
reservoir cap to allow venting. 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 filter guard, remove and re-
place the oil filter using an oil filter wrench.
Tighten filter by turning filter 3/4 to 1 turn after
gasket contacts the filter base surface. Rein-
stall the oil filter guard. Refer to

4. Remove the oil reservoir hose attached to the
elbow on top of the transaxles. Remove the
elbow to access the oil fill 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 open-
ing.
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).
