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.
Gear Axle Lubrication
● The gear axle oil lubrication is SAE E.P.
80W-90 (API GL-5) gear lube.
● Check the axle oil level
after every 100 hours
of operation by removing the oil level plug. If
additional oil is needed, remove the breather
vent on top of ax le and fill until oil is at the level
plug.
● Change axle oil every
1000 hours or two (2)
years.
Grease Fitting and Oil Point Lubrication
Lubricate the grease fittings and oil points
after
every 25 hours
of operation. Lubricate
more
often
when operating in
dusty or dirty condi-
tions.
Use SAE general purpose lithium or molyb-
denum base grease for grease fittings and light
machine oil (SAE 10) to lubricate oil points. Lubri-
cate the locations shown in the
Chassis and Deck
Lubrication Points
illustration on page 63.
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 fittings.
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 Installa-
tion on page 22
