2. Clean the area around the individual gearbox
cover plates to prevent contaminants from en-
tering the gearcase.
3. Remove the screws securing the cover plates
on the blade drive gearboxes.
4. Check the level of lubricant in the gearboxes. If
the lubricant is low, add SAE E.P. (Extreme
Pressure) 80W-90 (API GL-5) gear lube until
the oil level is up to (submerges) the horizontal
shaft in the gearbox (shaft parallel to cover
plate).
NOTE:
In case the gearboxes are completely
drained of oil, approximately 5 fl. oz. (15 cl) of oil
per gearbox is required to refill the gear drive
assembly.
NOTE:
Since the gearboxes are connected as
a unit by connector tubes, it is necessary to add
oil slowly. Allow a few minutes after adding oil
for the oil to flow throughout the assembly and
the oil level to stabilize before reassembly.
IMPORTANT:
DO NOT
overfill the deck gear-
boxes. The gearbox assembly is not vented,
and overfilling with oil will cause excessive pres-
sure and result in oil leaks.
5. Check condition of the cover gasket and replace
if worn or damaged. Reinstall gearbox cover
plates; torque screws to 24 lb

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 25
hours
with SAE general purpose lithium or
molybdenum base grease.
