MAINTENANCE

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 bat- tery 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 Adjustment section of this manual).

V-BELTS

CheckV-belts for deterioration and wear after 100 hours 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

							SAE 30
			5W-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

FIG. 11

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 Figs. 11 and 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 yellow cap from end of drain valve and install the drain tube onto the ﬁtting.

•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.

AIR FILTER (See Fig. 13)

Your engine will not run properly using a dirty air ﬁlter. Replace pre-cleaner after every 25 hours of operation or every season. Service paper cartridge every 100 hours of operation or every season, whichever occurs ﬁrst.

Service air cleaner more often under dusty conditions.

•Pull up on air ﬁlter cover handle and rotate towards engine.

•Remove cover.

•Carefully remove air ﬁlter cartridge and pre-cleaner from base.

•Clean base carefully to prevent debris from falling into carburetor.

NOTE: If very dirty or damaged, replace cartridge.

•Place new pre-cleaner and cartridge ﬁrmly in base.

•Align tabs on cover with slots in blower housing and replace cover.

•Hook handle on cover and push down on handle to close.

IMPORTANT: Petroleum solvents, such as kerosene, are not to be used to clean the cartridge. They may cause deterioration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean cartridge.
