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

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.
