MAINTENANCE
V-BELTS
Check V-belts for deterioration and wear after 100 hours and
replace if necessary. The belts are not adjustable. Re place
belts if they begin to slip from wear.
TRANSAXLE COOLING
Keep transaxle free from build-up of dirt and chaff which
can restrict cooling.

TO CHANGE ENGINE OIL (See Figs. 15 and 16)
Determine temperature range expected before oil change.
All oil must meet API service classifi cation SG-SL.
• Be sure tractor is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• 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.
• Unlock drain valve by pushing inward and turning
coun ter clock wise.
• To open, pull out on the drain valve.
• After oil has drained completely, close and lock the
drain valve by pushing inward and turning clockwise
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.
Be sure dipstick cap is tightened securely for accurate
reading. Keep oil at “FULL” line on dipstick. Tighten cap
onto the tube securely when fi nished.
YEL LOW CAP
• Clean terminals and battery cable ends with wire brush
until bright.
• Coat terminals with grease or petroleum jelly.
• Reinstall battery (See “CONNECT BATTERY” in the
Assembly sec tion of this manual).
CLEAN AIR SCREEN
Air screen must be kept free of dirt and chaff to prevent
engine dam age from overheating. Clean with a wire brush
or com pressed air to re move dirt and stubborn dried gum
fi bers.
ENGINE
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. When
operating in temperatures below 0º F (-18º C) syn thet ic
oil must be used.
* CAUTION:
Air cooled engines run hotter than automo-
tive engines. The use of non-synthetic multi-viscosity oils
(5W30, 10W30 etc.) in temperatures above 40º F (4º C) will
result in higher than normal oil consumption. When using
a multi-viscosity oil, check oil level more frequently.
** CAUTION:
SAE 30 oil, if used below 40º F (4º C), will
result in hard starting and possible engine bore damage
due to inadequate lubrication.
NOTE:
Synthetic oil meeting ILSAC GF-2, API
certifi cation mark and API service symbol (shown
at left) with "SJ/CF ENERGY CONSERVING" or
higher, is an acceptable oil at all temperatures.
Use of synthetic oil does not alter required
oil change intervals.
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.

AIR FILTER (See Fig. 17)
Your engine will not run properly using a dirty air fi lter. Clean
the foam pre-cleaner after every 25 hours of op er a tion or
every season. Service paper cartridge every 100 hours of
operation or every season, whichever occurs fi rst.
Service air cleaner more often under dusty conditions.
• Remove cover.
TO SERVICE PRE-CLEANER
• Wash it in liquid detergent and water.
• Squeeze it dry in a clean cloth.
• Saturate it in engine oil. Wrap it in clean, absorbent
cloth and squeeze to remove excess oil.
• If very dirty or damaged, replace pre-cleaner.
