DS52 or DS62 Mower Deck Lubrication
There are several special lubrication requirements
for the DS52 or DS62 mower deck in addition to the
require ments detailed in the Chassis and Deck
Lubrica tion Points illustration. Lubricate the loca-
tions shown in the Gearbox, Dol ly 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 8
hours with SAE general purpose lithium or
molybdenum base grease.

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 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 plugs.
4. Remove the oil reservoir hose attached to the
elbow on top of the transaxles and remove the
elbows to access the oil fill openings.
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 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).
