Reinstall Transaxle Elbows
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. If oil needs to be added refer back to steps 5-10.
12. 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.
Mower Deck Spindle Lubrication
For belt driven decks, lubricate each deck spindle
grease fitting
every 25 hours.
Use SAE general
purpose lithium or molybdenum base grease for
grease fittings.
Transaxle Lubrication
•
The transaxle oil lubrication is SAE 20W-50 (API
Service Class SL or higher) engine oil.
•
Inspect both transaxle cases and hoses
after ev-
ery 25 hours
of operation for visible leaks.
•
The fluid level of each transaxle 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 reservoir should be between
1/4 in. and 1/2 in. (0.64 cm and 1.27 cm).

CLEANING
CAUTION
If a pressure washer is used on the ex-
posed working parts, avoid water on the
electrical parts and the engine cooling sys-
tem.
Engine Air Cooling System
To prevent engine overheating and possible engine
damage, clean grass clippings, chaff and dirt from
the rotating engine air intake screen
every 8 hours
of operation. In certain mowing conditions (dry
grass, leaves, tree “cotton”, etc.) it may be neces-
sary to check and clean this area several times each
day to prevent engine overheating. Also, visually
check inside cylinder head shroud and between cyl-
inder head fins for material packed in this area which
would prevent cooling airflow; remove shroud and
clean as required.
