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.

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 fi ll
cap/dipstick securely each time you check the oil level.
TO CHANGE ENGINE OIL (See Fig. 21-23)
Determine temperature range expected before oil change.
All oil must meet API service classifi cation SG-SL.
•
Ensure tractor is on level surface.
•
Oil will drain more freely when warm.
•
Catch oil in a suitable container.
LOWER DASH COVER REMOVAL
•
Raise hood.
•
Remove fastener from lower dash cover.
CAUTION: Remove lower dash cover carefully to ensure
cover tabs are not broken.
•
Slide lower dash cover up to release cover tabs from
tapered slots in lower dash and remove.
LOWER DASH COVER
TABS
•
Remove oil fi ll cap/dipstick. Be careful not to allow dirt
to enter the engine when changing oil.
•
Remove yellow cap from end of drain valve and install
the drain tube onto the fi tting.

•
After oil has drained completely, close and lock the

until the pin is in the locked position as shown.
•
Remove the drain tube and replace the cap onto to the
bottom fi tting of the drain valve.
•
Refi ll engine with oil through oil fi ll dipstick tube. Pour
slowly. Do not overfi ll. For approximate capacity see
"PRODUCT SPECIFICATIONS" section of this man u al.
•
Use gauge on oil fi ll cap/dipstick for checking level.
Ensure dipstick cap is tightened securely for accurate
reading. Keep oil at "FULL" line on dipstick. Tighten
cap onto the tube securely when fi nished.
ENGINE OIL FILTER
Replace the engine oil fi lter every season or every other
oil change if the tractor is used more than 100 hours in
one year.
NOTE: If needed, remove lower dash covers using steps
from "Lower dash cover removal" section of this manual.
AIR FILTER
Your engine will not run properly using a dirty air fi lter. Ser-
vice air cleaner more often under dusty conditions.
CLEAN AIR SCREEN
The air screen is over the air intake blower located on top
of engine. The air screen must be kept free of dirt and
chaff to prevent engine dam age from overheating. Clean
with a wire brush or compressed air to re move dirt and
stubborn dried gum fi bers.
ENGINE COOLING SYSTEM
To ensure proper cooling, make sure the grass screen,
cooling fi ns, and other external surfaces of the engine are
kept clean at all times.
Every 100 hours of operation (more often under extremely
dusty, dirty conditions), remove the blower housing and other
cooling shrouds. Clean the cooling fi ns and external surfaces
as necessary. Ensure the cooling shrouds are reinstalled.
SLOTS
NOTE: Operating the engine with a blocked grass screen,
dirty or plugged cooling fi ns, and/or cooling shrouds re moved
will cause engine damage due to overheating.
SPARK PLUGS
Replace spark plugs at the beginning of each mowing
season or after every 100 hours of operation, whichever
occurs fi rst. Spark plug type and gap setting are shown in
"PROD UCT SPECIFICATIONS" section of this manual.
