See “TO LEVEL MOWER HOUSING” in the Service and Adjustments section of this manual. YOUR MOWER CAME FACTORY EQUIPPED WITH HIGH PERFORMANCE BLADES, WHICH ARE THE BEST BLADES FOR BAGGING AND DISCHARGING.
OPERATION These symbols may appear on your tractor or in literature supplied with the product. Learn and understand their meaning.
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.
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 a wide vision safety mask over spectacles or standard safety glasses. HOW TO USE YOUR TRACTOR • TO SET PARKING BRAKE (See Fig. 6) IMPORTANT:LEAVING THE IGNITION SWITCH IN ANY POSITION OTHER THAN "OFF" WILL CAUSE THE BATTERY TO BE DISCHARGED, (DEAD).
OPERATION • For best cutting performance, grass over 6 inches in height should be mowed twice. Make the first cut relatively high; the second to desired height. "ENGAGED" POSITION ATTACHMENT LIFT LEVER HIGH POSITION TO ADJUST GAUGE WHEELS (See Fig. 7) ATTACHMENT CLUTCH LEVER "DISENGAGED" POSITION Gauge wheels are properly adjusted when they are slightly off the ground when mower is at the desired cutting height in operating position.
OPERATION Transmission Engaged CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season.
OPERATION AUTOMATIC TRANSMISSION WARM UP • Before driving the unit in cold weather, the transmission should be warmed up as follows: • Be sure the tractor is on level ground. • Place the motion control lever in neutral. Release the parking brake and let the clutch/brake slowly return to operating position. • Allow one minute for transmission to warm up. This can be done during the engine warm up period.
OPERATION MULCHING MOWING TIPS IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN AFTER EACH USE. • • • MAX 1/3 The special mulching blade will recut the grass clippings many times and reduce them in size so that as they fall onto the lawn they will disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quickly to provide nutrients for the lawn.

MAINTENANCE TRACTOR MANDREL ASSEMBLY TRAILING EDGE UP BLADE Always observe safety rules when performing any maintenance. CENTER HOLE BRAKE OPERATION If tractor requires more than six (6) feet stopping distance at high speed in highest gear, then brake must be adjusted. (See “TO ADJUST BRAKE” in the Service and Adjustments section of this manual). FLAT WASHER LOCK WASHER STAR TIRES • Maintain proper air pressure in all tires (See “PRODUCT SPECIFICATIONS” section of this manual).
MAINTENANCE 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.
MAINTENANCE CLEAN AIR SCREEN ENGINE OIL FILTER 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. Replace the engine oil filter every season or every other oil change if the tractor is used more than 100 hours in one year.
SERVICE AND ADJUSTMENTS WARNING: TO AVOID SERIOUS INJURY, BEFORE PERFORMING ANY SERVICE OR ADJUSTMENTS • Depress clutch/brake pedal fully and set parking brake. • Place motion control lever in neutral (N) position. • 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.
SERVICE AND ADJUSTMENTS • TO LEVEL MOWER HOUSING Adjust the mower while tractor is parked on level ground or driveway. Make sure tires are properly inflated (See “PRODUCT SPECIFICATIONS” section of this manual). If tires are over or underinflated, you will not properly adjust your mower. • • • SIDE-TO-SIDE ADJUSTMENT (See Figs. 19 and 20) • Raise mower to its highest position. • At the midpoint of both sides of mower, measure height from bottom edge of mower to ground.
SERVICE AND ADJUSTMENTS • TO REPLACE MOWER BLADE DRIVE BELT (See Fig. 23) The mower blade drive belt may be replaced without tools. Park the tractor on level surface. Engage parking brake. BELT REMOVAL • Remove mower from tractor (See “TO REMOVE MOWER” in this section of manual). • Work belt off both mandrel pulleys and idler pulleys. • Pull belt away from mower. BELT INSTALLATION • Work belt around both mandrel pulleys and idler pulleys.

SERVICE AND ADJUSTMENTS • TO START ENGINE WITH A WEAK BATTERY (See Fig. 28) • WARNING: Lead-acid batteries generate explosive gases. Keep sparks, flame and smoking materials away from batteries. Always wear eye protection when around batteries. • If your battery is too weak to start the engine, it should be recharged. (See "BATTERY" in the MAINTENANCE section of this manual).
SERVICE AND ADJUSTMENTS TO REMOVE HOOD AND GRILL ASSEMBLY (See Fig. 31) • • • • TO ADJUST CARBURETOR Your carburetor is not adjustable. If your engine does not operate properly due to suspected carburetor problems, take your tractor to an authorized service center for repair and/or adjustment. High speed stop is factory adjusted. Do not adjust - damage may result. Raise hood. Unsnap headlight wire connector. Stand in front of tractor. Grasp hood at sides, tilt toward engine and lift off of tractor.
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.
