DS52 Mower Deck Lubrication
There are several special lubrication requirements
for the DS52 mower deck in addition to the require-
ments detailed in the Chassis and Deck Lubrica-
tion Points illustration. Lubricate the locations
shown in the Gearbox, Dolly Wheel, and U-Joint
Lubrication photo and check and maintain oil in
the belt drive gearbox.
1. Check the oil level in the belt drive gearbox
ev ery 100 hours (or sooner if a visible oil leak
has developed). With the deck in the normal
oper ating position, remove the level plug in the
side of the gearcase. Add SAE E.P. (Extreme
Pres sure) 80W-90 (API GL-5) gear lube to
maintain the oil level to the plug. If the oil level
is low, check the gear box for any indication of
an oil leak. If an oil leak is noted, the gearbox
will need to be removed and rebuilt.
2. Lubricate the dolly wheel pivot every 25 hours
with general purpose grease.
3. Lubricate both drive shaft u-joints every 25
hours with SAE general purpose lithium or
molybdenum base grease.

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 uid level of the transaxles can be
checked visually by looking at the uid level in
the expansion reservoir. When the transaxles
are cold, the uid level in the expansion
reservoir should be between 1/4 in. and 1/2 in.
(6-13 mm) from the bottom, near the Cold
Level line.

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 lter guard, remove and re-
place 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. Rein-
stall the oil lter guard. Refer to Transaxle Oil
Drain Plug, Filter, and Guard Location illus-
