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.

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. 10

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. 10 and 11)

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

Your engine will not run properly using a dirty air ﬁlter. Service air cleaner more often under dusty conditions. See Engine Manual.

ENGINE OIL FILTER

Replace the engine oil ﬁlter every season or every other oil change if the tractor is used more than 100 hours in one year.

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.
