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
overfill the PTO gearbox to
avoid oil leakage out of the dipstick standpipe.

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.
