•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).
TO CHANGE ENGINE OIL (See Figs. 11 and 12)
Determine temperature range expected before oil change. All oil must meet API service classification
•Be sure tractor is on level surface.
•Oil will drain more freely when warm.
•Catch oil in a suitable container.

TRANSAXLE COOLING
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- sible damage to seals, do not use high pressure water or steam to clean transaxle.
•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 com- pressed air or high pressure sprayer to clean cooling fins.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory and fluid mainte- nance is not required for the life of the transaxle. Should the transaxle ever leak or require servicing, contact your nearest authorized service center/department.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
FIG. 11 |
|
NOTE: Although |
|
improve starting in cold weather, these |
|
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 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 | 17 |
cap/dipstick securely each time you check the oil level. |

•Unlock drain valve by pushing inward and turning counterclockwise.
•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 fitting of the drain valve.
•Refill engine with oil through oil fill dipstick tube. Pour slowly. Do not overfill. For approximate capacity see “PRODUCT SPECIFICATIONS” section of this man- ual.
•Use gauge on oil fill cap/dipstick for checking level. Be sure dipstick cap is tightened securely for accurate reading. Keep oil at “FULL” line on dipstick.
CLEAN AIR SCREEN
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. See engine manual.
ENGINE COOLING FINS (See Fig. 13)
Remove any dust, dirt or oil from engine cooling fins to prevent engine damage from overheating.
•Remove screws from blower housing and lift housing and dipstick tube assembly off engine.
•Cover oil fill opening to prevent entry of dirt.
•Use compressed air or stiff bristle brush to thoroughly clean engine cooling fins.
•To reassemble, reverse above procedure.
