MAINTENANCE 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 MAINTENANCE 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 possible damage to seals, do not use high pressure water or steam to clean transmission. • 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 compressed air or high pressure sprayer to clean cooling fins. TRANSAXLE PUMP FLUID The transaxle was sealed at the factory and fluid maintenance is not required for the life of the transaxle. Should the transaxle ever leak or require servicing, contact your nearest authorized service center/department. ENGINE LOWER DASH COVER FASTENER SLOTS TABS Fig. 15 • Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine when changing oil. • Install the drain tube onto the valve. • Open drain valve by using a 10mm wrench turning counterclockwise. OIL DRAIN VALVE TO OPEN 02794 TO CLOSE DRAIN TUBE LUBRICATION Only use high quality detergent oil rated with API service classification SG-SL. Select the oil's SAE viscosity grade according to your expected operating temperature. SAE VISCOSITY GRADES Fig. 16 • After oil has drained completely, close the drain valve turning clockwise. Use the 10mm wrench to apply a small amount of torque to keep it closed. Do not over tighten. • Remove the drain tube and store in a safe place. 5W-30 SAE 30 • Refill engine with oil through oil fill dipstick tube. Pour slowly. Do not overfill.

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. • Use gauge on oil fill cap/dipstick for checking level. Insert dipstick into the tube and rest the oil fill cap on the tube. Do not thread the cap onto the tube when taking reading. Keep oil at "FULL" line on dipstick. Tighten cap onto the tube securely when finished. 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 SCREEN 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. 15 & 16) 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 Determine temperature range expected before oil change. All oil must meet API service classification SG-SL. Your engine will not run properly using a dirty air filter. Service air cleaner more often under dusty conditions. • Be sure tractor is on level surface. ENGINE COOLING SYSTEM • Oil will drain more freely when warm. To ensure proper cooling, make sure the grass screen, • Catch oil in a suitable container. cooling fins, and other external surfaces of the engine are LEFT LOWER DASH COVER REMOVAL kept clean at all times. • Raise hood.

Clean the cooling fins and external surfaces CAUTION: Remove lower dash cover carefully to ensure as necessary. Ensure the cooling shrouds are reinstalled. cover tabs are not broken. NOTE: Operating the engine with a blocked grass screen, • Slide lower dash cover up to release cover tabs from tapered slots in lower dash and remove. 16 dirty or plugged cooling fins, and/or cooling shrouds removed will cause engine damage due to overheating.
