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 overll 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. Rell 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 relling.
3. Check that the oil level is at the FULL mark on
the dipstick. DO NOT overll.
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 ll until oil is at the level plug.
• Change axle oil every 1000 hours or two (2)
years.
Hydrostatic Transmission Fluid
Checking Hydrostatic Transmission Fluid Level
The hydrostatic transmissions are sealed units
and do not need to be opened to check the uid
level. Hydrostatic uid level should be checked ev-
ery 25 hours of machine operation. It is preferable
to check the uid when the uid is cold. Check
uid levels as follows:
IMPORTANT: Removing or breaking the seal on
the hydrostatic reservoir cap within the rst
1000 hours will VOID THE TRANSMISSION WAR-
RANTY.
1. Park the mower on a level surface. Stop the
engine and wipe dirt and contaminants from
around the base of the reservoir to better see
the COLD mark.
2. The level of the oil can be seen through the side
of the opaque reservoir (DO NOT REMOVE
RESERVOIR CAP); using a light next to the
reservoir will help make the level more visible.
