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.
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 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.
