CUSTOMER RESPONSlBlLrnFS
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.
• Wash battery with solution of four tablespoons of
baking soda to one gallon of water. Be careful not to get
the soda solution into the cells.
• 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 “INSTALL BATTERY” in the
Assembly section of this manual).
V-BELTS
Check V-Belts for deterioration and wear after 100 hours
and replace
if necessary. The mower blade drive and
motion drive belts are not adjustable. Replace belts if they
begin to slip from wear.
TRANSAXLE COOLING
Keep transaxle free from build-up of dirt and chaff which
can restrict cooling.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SG. Select the oil's SAE viscosity grade
according to your expected operating temperature.
SAE VISCOSITY GRADES
°F -20" 0° 30° 32° 40° 60° 80° 100°
‘’c -30'’ 20" -10" 0° 10° 20° 30° 40°
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils (5W30, 10W30, etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32° F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
Change the oil after the first two hours of operation and
every 25 hours thereafter or at least once a year if the
tractor is not used for 25 hours in one year.
Check the crankcase oil level before starting the engine
and after each eight (8) hours of continuous use. Tighten
oil fill cap/dipstick securely each time you check the oil
level.
TO CHANGE ENGINE OIL (See Fig. 18)
Determine temperature range expected before oil change.
All oil must meet API service classification SG.
• Be sure tractor is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• Remove oil fill cap/dipstick. Be careful not to allow dirt
to enter the engine when changing oil.
• Remove drain plug.
• After oil has drained completely, replace oil drain plug
and tighten securely.
• Refill engine with oil through oil fill dipstick tube. Pour
slowly. Do not overfill. For approximate capacity see
“PRODUCT SPECIFICATIONS” on page 3 of this
manual.
• Use gauge on dipstick for checking level. Be sure
dipstick cap is tightened securely for accurate reading.
Keep oil at “FULL” line on dipstick.
CLEAN AIR SCREEN (See Fig. 18)
The air screen must be kept free of dirt and chaff to prevent
engine damage from overheating. Clean with a wire brush
or compressed air to remove dirt and stubborn dried gum
fibers.
CLEAN ENGINE COOLING FINS
(See Fig. 19)
Remove any dust, dirt or oil from engine cooling fins to
prevent engine damage from overheating. Air guide covers
must be removed. Remove side panels and hood (See “TO
REMOVE HOOD AND GRILL ASSEMBLY” in the Service
and Adjustments section of this manual).
