REAR WHEEL GEAR DRIVE ONLY: • If you remove the drive pinions, wipe clean with dry cloth. Reassemble dry. Do not lubricate. Do not use oil or grease. NOTE: The pinion gears, on both sides of the mower, are the same, however, they must be installed correctly. If installed incorrectly, the drive system will not work. • There are arrows embossed on both sides of the pinion gear. With the arrow at the top of the pinion, the arrow must point towards the front of the mower. If the arrow points to the rear of the mower, turn the pinion around, then assemble to mower.

LUBRICATION Change the oil after the first two hours of operation and every 25 hours thereafter or at least once a year if the lawn mower is not used for 25 hours in one year. Refer to engine manual. TO CHANGE ENGINE OIL (SEE ENGINE MANUAL) • Be sure lawn mower is on level surface. • Oil will drain more freely when warm. • Catch oil in a suitable container. • For engines without dipstick, remove bottom oil drain plug. • For engines with oil fill cap/dipstick, remove bottom drain plug or remove engine oil cap and turn mower on its side. • After oil has drained completely, replace oil drain plug and tighten securely. • Refill engine with oil. Pour slowly. Do not overfill. • Fill to top of slot inside of filler hole or to "FULL" line on dipstick on models so equipped. Keep oil at proper level.

Clean under the drive cover twice a season. • The gear case is filled with lubricant to the proper level at the factory.
