GEARBOX MAINTENANCE
Check Gearbox Oil Level
1. Remove fill plug (A, Figure 49) on gearbox.
2. Once plug is removed, oil should seep out of fill
plug hole. If no oil drains out, fill with SAE 80-90
weight gear oil until oil starts to seep from hole,
then replace fill plug.
Changing Gearbox Oil
NOTE: The gearbox lubricant should be changed
after the first 100 hrs. or 30 days of operation, then
after 500 hours or 12 months.
1. Remove the mower deck drive belt (see MOWER
DRIVE BELT REMOVAL & REPLACEMENT for
instructions).
2. Rotate the the mower deck drive pulley on the
gearbox so the drain plug is aligned with the
opening between the pulley spokes.
3. Place a container under the gearbox drain hole
and remove the drain plug (B).
4. Replace drain plug and fill with SAE 80-90 weight
gear oil until oil starts to seep from hole, then
replace fill plug.
5. Using a parts solvent, thoroughly clean any
excess oil from the pulley faces and groove.
6. Reinstall the mower deck drive belt (see MOWER
DRIVE BELT REMOVAL & REPLACEMENT for
instructions).
DECK SHUT DOWN MODULE
This unit is equipped with a deck shut down module
that will automatically shut down the mower deck if the
engine looses oil pressure or begins to overheat.
What to do if the deck shuts down during
operation:
• Immediately check your dash panel to see if the
oil pressure indicator lamp (A, Figure 50) is lit or
the water temperature gauge (B) is reading a high
temperature.
If the oil pressure indicator lamp is lit:
• Shut the unit off immediately and see your dealer.
If the water temperature guage reads a high
temperature:
• Move the ground speed control levers to the
neutral position, disengage the PTO switch,
engage the parking brake and reduce to half
throttle speed. Leave the engine running so the
radiator fan will continue to run and coolant will
continue to circulate.
• Check the engine coolant level. See Check Engine
Coolant Level. Add coolant if necessary.
• Check to see if the radiator screen is dirty or
plugged. See Clean Radiator & Screen. Clean
radiator screen if necessary.
• If these procedures do not cause the engine to
begin to cool down, shut the unit off and see your
dealer.
After the Problem has been resolved
• The PTO switch must be disengaged before it can
be re-engaged.
