MAINTENANCE
TRANSAXLE COOLING
The fan and cooling fi ns of transmission should be kept
clean to assure proper cooling.
Do not attempt to clean fan or transmission while engine
is running or while the transmission is hot. To prevent pos-
sible damage to seals, no not use high pressure water or
steam to clean transaxle.
• Inspect cooling fan to be sure fan blades are intact and
clean.
• Inspect cooling fi ns for dirt, grass clippings and other
ma te ri als. To prevent damage to seals, do not use
compressed air or high pressure sprayer to clean cool-
ing fi ns.
V-BELTS
Check V-belts for deterioration and wear after 100 hours
of operation and replace if necessary. The belts are not
ad just able. Re place belts if they begin to slip from wear.

BATTERY
Your tractor has a battery charging system which is suf cient
for normal use. However, periodic charging of the battery
with an automotive charger will extend its life.
• Keep battery and terminals clean.
• Keep battery bolts tight.
• Keep small vent holes open.
• Recharge at 6-10 amperes for 1 hour.
NOTE: The original equipment battery on your tractor is
maintenance free. Do not attempt to open or remove caps
or covers. Adding or checking level of electrolyte is not
necessary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to “leak” power.
• Remove terminal guard.
Disconnect BLACK battery cable fi rst then RED bat-
tery cable and remove battery from tractor.
• Rinse the battery with plain water and dry.
• Clean terminals and battery cable ends with wire brush
until bright.
• Coat terminals with grease or petroleum jelly.
• Reinstall battery (See “REPLACING BATTERY” in
the SERVICE AND ADJUSTMENTS section of this
man u al).
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory and fl uid main te -
nance is not required for the life of the transaxle. Should
the transaxle ever leak or require servicing, contact your
near est au tho rized ser vice center/department.

LUBRICATION
Only use high quality detergent oil rated with API service
classifi cation SG-SL. Select the oil’s SAE viscosity grade
according to your expected operating temperature.
Change the oil after every 50 hours of operation or at least
once a year if the tractor is not used for 50 hours in one
year.
Check the crankcase oil level before starting the engine
and after each eight (8) hours of operation.
