Maintenance Instructions

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.

Checking Gearbox Oil Level

Check the gearbox oil level every 25 hours, and if
necessary, add oil [SAE E.P. (Extreme Pressure)
80W-90 (API GL-5) gear lube] to maintain oil level to
the FULL mark on the dipstick.
IMPORTANT: DO NOT overfill the PTO gearbox to
avoid oil leakage out of the dipstick standpipe.
If the oil level is low, check the gearbox for any indi-
cation of an oil leak. If an oil leak is noted, the gear-
box will need to be removed and rebuilt.

Changing Gearbox Oil

The tractor PTO gearbox is oil filled. No scheduled
oil change is required. However, changing the oil
af ter the first 100 hour break-in period will extend
gearbox life and is recommended.
1. Remove the drain plug in the bottom of the
gearcase, drain the oil, and reinstall the plug.
2. Refill the gearbox through the dipstick stand-
pipe using 7 to 8 fl. oz. (21 to 24 cl) of SAE E.P.
(Extreme Pressure) 80W-90 (API GL-5) gear
lube. Re move plug in top of gearcase to vent
air when refilling.
3. Check that the oil level is at the FULL mark on
the dipstick. DO NOT overfill.
