Maintenance Instructions LUBRICATION
Mower Deck Spindle Lubrication
Lubricate each deck spindle grease tting every 25
hours. Use SAE general purpose lithium or molyb
denum base grease for grease ttings.
DR52, DS60 or DR64 Mower Deck Lubrication
Lubricate the UJoint in the PTO drive shaft every 25
hours with SAE general purpose lithium or molyb
denum base grease.
Check Transaxle Fluid Level
● The transaxle oil lubrication is SAE 20W50 (API
Service Class SL or higher) engine oil.
● Inspect both transaxle cases 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 expan
sion reservoir. When the transaxles are cold, the
uid level in the expansion reservoir should be
between 1/4 and 1/2 in. (0.64 cm and 1.27 cm).

Grease Fitting and Oil Point Lubrication
Lubricate the grease ttings and oil points after ev-
ery 25 hours of operation. Lubricate more often
when operating in dusty or dirty conditions. Use
SAE general purpose lithium or molybdenum base
grease for grease ttings and light machine oil
(SAE 10) to lubricate oil points. Lubricate the
locations shown in the Chassis and Deck
Lubrication Points illustration.
NOTE: PTO universal joints (on the deck and trac
tor) require routine lubrication after every 25
hours of running time. Remove tractor PTO quick
disconnect tube assembly for easy access to
grease ttings.
NOTE: The best way to lubricate the PTO tube half
of the universal joint assembly is to remove it from
the tractor. See instructions for removing and install
ing PTO quick coupler, refer to Deck Installation in
Mower Deck Installation on Tractor in the Assem
bly Instructions.
NOTE: The ball bearings on the PTO drive shaft are
sealed and do not require periodic maintenance.
