OPERATION KNOW YOUR TRACTOR READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR TRACTOR Compare the illustrations with your tractor to familiarize yourself with the locations of various controls and adjustments. Save this manual for future reference. P H D E B G F C J A K L M Fig. 3 Our tractors conform to the applicable safety standards of the American National Standards Institute.
OPERATION The operation of any tractor can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your tractor or performing any adjustments or repairs. We recommend standard safety glasses or a wide vision safety mask worn over spectacles. GROUND DRIVE • To stop ground drive, depress brake pedal into full “BRAKE” position. HOW TO USE YOUR TRACTOR TO SET PARKING BRAKE (See Fig.
OPERATION TO MOVE FORWARD AND BACKWARD (See Fig. 7) • Put attachment lift lever in desired cutting height slot. The cutting height range is approximately 1" to 4". The heights are measured from the ground to the blade tip with the engine not running. These heights are approximate and may vary depending upon soil conditions, height of grass and types of grass being mowed. • The average lawn should be cut to approximately 2-1/2" during the cool season and to over 3" during hot months.
OPERATION TO OPERATE MOWER Your tractor is equipped with an operator presence sensing switch. Any attempt by the operator to leave the seat with the engine running and the attachment clutch engaged will shut off the engine. You must remain fully and centrally positioned in the seat to prevent the engine from hesitating or cutting off when operating your equipment on rough, rolling terrain or hills. 1. Select desired height of cut with attachment lift lever. 2.
OPERATION TO START ENGINE (See Fig. 3) SERVICE REMINDER/HOUR METER When starting the engine for the first time or if the engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine. • Be sure freewheel control is in the transmission engaged position. • Sit on seat in operating position, depress brake pedal and set parking brake. • Move attachment clutch to “DISENGAGED” position. • Move throttle control to choke position.
OPERATION MOWING TIPS PURGE TRANSMISSION • CAUTION: Never engage or disengage freewheel lever while the engine is running. • • To ensure proper operation and performance, it is recommended that the transmission be purged before operating tractor for the first time. This procedure will remove any trapped air inside the transmission which may have developed during shipping of your tractor.

MAINTENANCE BLADE CARE TRACTOR For best results mower blades must be sharp. Replace worn, bent or damaged blades. Always observe safety rules when performing any maintenance. BRAKE OPERATION CAUTION: Use only a replacement blade approved by the manufacturer of your tractor. Using a blade not approved by the manufacturer of your tractor is hazardous, could damage your tractor and void your warranty.
MAINTENANCE NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, they 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.
MAINTENANCE CLEAN AIR SCREEN DECK WASHOUT PORT (See Fig. 17) 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. Your tractor’s deck is equipped with a washout port on its surface as part of its deck wash system. It should be utilized after each use. 1. Drive the tractor to a level, clear spot on your lawn, near enough to a water spigot for your garden hose to reach.
SERVICE AND ADJUSTMENTS WARNING: TO AVOID SERIOUS INJURY, BEFORE PERFORMING ANY SERVICE OR ADJUSTMENTS: • Depress brake pedal fully and set parking brake. • Place attachment clutch in “DISENGAGED” position. • Turn ignition key to “STOP” and remove key. • Make sure the blades and all moving parts have completely stopped. • Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug. TO REMOVE MOWER (See Fig.
SERVICE AND ADJUSTMENTS • • • ATTACH MOWER SIDE SUSPENSION ARMS (A) TO CHASSIS - Position hole in arm over pin (B) on outside of tractor chassis and secure with retainer spring. Repeat on opposite side of tractor. Insert end of link (E) into hole in front mower bracket and secure with washer and retainer spring (J). E A J F H B • Fig.
SERVICE AND ADJUSTMENTS TO LEVEL MOWER • Make sure tires are properly inflated to the PSI shown on tires. If tires are over or under inflated, it may affect the appearance of your lawn and lead you to think the mower is not adjusted properly. • If adjustment is necessary, see step in Visual Adjustment instructions above. Recheck measurements, adjust if necessary until both sides are equal. FRONT-TO-BACK ADJUSTMENT (See Figs. 26 & 27) IMPORTANT: Deck must be level side-to-side.
SERVICE AND ADJUSTMENTS TO REPLACE MOWER BLADE DRIVE BELT (See Fig. 28) BELT INSTALLATION • Install new belt from tractor rear to front, over the steering plate (F) and above clutch brake pedal shaft (G). • Pull belt toward front of tractor and roll belt onto engine pulley (E). • Pull belt toward rear of tractor. Carefully work belt down around transmission cooling fan and onto the input pulley (D). Be sure belt is inside the belt keeper. • Install belt on centerspan idler (C).
SERVICE AND ADJUSTMENTS FRONT WHEEL TOE-IN/CAMBER • Connect the other end of the BLACK cable (D) to good chassis ground, away from fuel tank and battery. Your new tractor front wheel toe-in and camber is set at the factory and is normal. The front wheel toe-in and camber are not adjustable. If damage has occurred to affect the factory set front wheel toe-in or camber, contact a qualified service center.
SERVICE AND ADJUSTMENTS TO REPLACE HEADLIGHT BULB • • • • ENGINE Raise hood. Pull bulb holder out of the hole in the backside of the grill. Replace bulb in holder and push bulb holder securely back into the hole in the backside of the grill. Close hood.

STORAGE Immediately prepare your tractor for storage at the end of the season or if the tractor will not be used for 30 days or more. ENGINE FUEL SYSTEM IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT ALCOHOL BLENDED FUELS (CALLED GASOHOL OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS TO SEPARATION AND FORMATION OF ACIDS DURING STORAGE.
