Tractor PTO Gearbox Lubrication
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 overll 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 lled. No scheduled
oil change is required. However, changing the oil
af ter the rst 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. Rell the gearbox through the dipstick stand-
pipe using 7 to 8 . 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 relling.
3. Check that the oil level is at the FULL mark on
the dipstick. DO NOT overll.
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 addi-
tional oil is needed, remove the breather vent on
top of ax le and ll until oil is at the level plug.
● Change axle oil every 1000 hours or two (2)
years.
