BATTERY
Your tractor has a battery charging system which is suf fi 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 first 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 manual.)

TRANSAXLE MAINTENANCE
The transmission fan and cooling fins 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-
si ble damage to seals, do not use high pressure water or
steam to clean transmission.
•
Inspect cooling fan to be sure fan blades are intact and
clean.
•
Inspect cooling fins for dirt, grass clippings and other
materials. To prevent damage to seals, do not use
compressed air or high pressure sprayer to clean
cool ing fins.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory and fluid 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.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SG-SL. Select the oil's SAE viscosity grade
according to your expected operating temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, they will result in increased
oil consumption when used above 32°F/0°C. Check your
engine oil level more frequently to avoid possible engine
damage from running low on oil.
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. Tighten oil fill
cap/dipstick securely each time you check the oil level.
