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 discon
nect tube assembly for easy access to grease t
tings.
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.
