2. Check the oil level in the belt drive gearbox ev-
ery 100 hours (or sooner if a visible oil leak has
developed). With the deck in the normal oper-
ating position, remove the level plug in the side
of the gearcase. Add SAE E.P. (Extreme Pres-
sure) 90W oil to maintain the oil level to the
plug. If the oil level is low, check the gearbox for
any indication of an oil leak. If an oil leak is not-
ed, the gearbox will need to be removed and re-
built.
3. Lubricate the dolly wheel pivot every 25 hours
with general purpose grease.
4. Lubricate the U-Joint in the drive shaft every
8 hours with SAE general purpose lithium or
molybdenum base grease.
Gearbox, Dolly Wheel, and U-Joint Lubrication
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)
90W 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.
Dipstick Location, Tractor PTO Gearbox
Changing Gearbox Oil
The tractor PTO gearbox is oil filled and vented. No
scheduled oil change is required. However, chang-
ing the oil after 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) 90W 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 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.
