SECTION 5: ENGINE MAINTENANCE
WARNING: Use care when servicing
any component in the engine area. If
the engine has recently been operated,
components will be hot and could
cause burns. Allow the engine to cool
before servicing.
WARNING: Before servicing the engine,
place the tractor on a level surface,
stop the engine, engage the parking
brake, and remove the key from the
ignition switch.
CLEANING THE ENGINE
This tractor has a liquid-cooled engine. Air must
freely circulate through the fins of the radiator and
the transmission oil cooler. Keep this area free of
accumulated dirt and debris to prevent engine over-
heating, which could possibly cause extensive
engine damage.
WARNING: Keep the muffler area clean.
Before running the engine, remove all
combustible debris from the muffler area.
CLEANING RADIATOR/RADIATOR SCREEN
To remove the radiator screen, lift the hood and care-
fully lift screen by the center tab. Flush the screen with
water to clean its surface. See Figure 50.
Figure 50
Check the radiator and transmission cooler fins for
any accumulation of debris lodged between cooling
fins. Blow the debris out using compressed air
directed from the fan shroud side of the radiator.
Reinsert the screen, making sure that it is in the
slots of the radiator frame.
CHECKING ENGINE OIL LEVEL
Before each use, the oil level in the engine
crankcase should be checked to see that it is filled
to the correct level. During the "break in" period for
the engine, closely monitor the engine oil level. The
oil level should be checked hourly during the first 5
hours of operation.
• Check the oil level only while the engine is
stopped and the tractor is level. Clean the area
around the oil level dipstick to prevent debris
from entering the crankcase. See Figure 51.
• If recently operated, allow the engine to cool
and the oil to drain back into the oil pan.
• To check the oil level, withdraw the dipstick and
wipe it clean. Reinsert the dipstick all the way
into the tube before withdrawing it for a true
reading.
Figure 51
• Always keep the oil level between the full and
the add marks on the dipstick. See Figure 52.
• Reinsert the dipstick into the dipstick tube and
push firmly into the tube.
