CUSTOMER RESPONSIBILITIES TO CLEAN BATTERY AND TERMINALS Corrosion and dirt on the battery and terminals can cause the battery to "leak" power. • Disconnect BLACK battery cable first then RED battery cable and remove battery from tractor. • 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 "REPLACING BATTERY" in the SERVICE AND ADJUSTMENTS section of this manual). V-BELTS Check V-belts for deterioration and wear after 100 hours of operation and replace if necessary. The 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 SF-SJ. Select the oil's SAE viscosity grade according to your expected operating temperature. SAE VISCOSITY GRADES 5W-30 SAE 30 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 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 cap/ dipstick securely each time you check the oil level. TO CHANGE ENGINE OIL (See Fig. 12) Determine temperature range expected before oil change. All oil must meet API service classification SF-SJ. • 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" section of this manual. • 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. AIR SCREEN OIL FILL CAP¦DIPSTSICK OIL DRAIN PLUG FIG. 12 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. CLEAN AIR INTAKE/COOLING AREAS To insure proper cooling, make sure the grass screen, cooling fins, 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 fins and external surfaces as necessary. Make sure the cooling shrouds are reinstalled. NOTE: Operating the engine with a blocked grass screen, dirty or plugged cooling fins, and/or cooling shrouds removed will cause engine damage due to overheating. 16

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.
CUSTOMER RESPONSIBILITIES
V-BELTS
Check V-belts for deterioration and wear after 100 hours of
operation and replace if necessary. The 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 SF-SJ.
Select the oil’s SAE viscosity grade
according to your expected operating temperature.
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 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 cap/
dipstick securely each time you check the oil level.
