Maintenance Instructions
LUBRICATION
Mower Deck Spindle Lubrication
Lubricate each deck spindle grease fitting
every 25
hours.
Use SAE general purpose lithium or molyb-
denum base grease for grease fittings.
DRD52 or DSD60 Mower Deck Lubrication
Lubricate the U-Joint in the drive shaft
every 8 hours
with SAE general purpose lithium or molybdenum
base grease.
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
every 100 hours
of operation for visible leaks.
•
The fluid levels for each transaxle can be checked
visually by looking at the fluid levels in each expansion
reservoir. When the transaxles are cold, the fluid
level in the expansion reservoirs should be between
1/4 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 pe-
riod
of
75-100 hours.
Thereafter, change oil
every
400 hours
of operation as follows:
1. Thoroughly clean the exterior of the transmission
housing before servicing. Remove expansion
tank 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 replace
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. Reinstall the oil
filter guard. (Refer to
Transaxle Oil Drain Plug,
Filter, and Guard Location
illustration.)

3. Reinstall drain plug.
4. Remove the oil reservoir hose attached to the
elbow on top of the transaxle. 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 opening.
6.
Before reinstalling the elbows, screw the locking
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).
