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. Remove 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.
