Smart Speed™ Control System Lever Operation The Smart Speed™ Control-System lever, located below the operating position, gives the operator a choice to drive the machine at 3 speed ranges— trim, tow, and mow (Figure 5). Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.
Think Safety First CAUTION This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Operating Safety Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets, or bystanders avoid injury. Wear hearing protection when operating this machine. DANGER The use of protective equipment for eyes, ears, hands, feet, and head is recommended.
Understanding the Safety-Interlock System 12. While the engine is running, move the motion-control levers to the center, unlocked position, engage the blade-control switch, and rise slightly from the seat. WARNING Note: The engine should stop. If safety-interlock switches are disconnected or damaged, the machine could operate unexpectedly causing personal injury. Starting the Engine Important: Do not engage the starter for more than 10 seconds at a time.
Operating the Blades Stopping the Engine 1. Disengage the blades by moving the blade-control switch to Off (Figure 12). The blade-control switch, represented by a power take-off (PTO) symbol, engages and disengages power to the mower blades. This switch controls power to any attachments that draw power from the engine, including the mower deck and cutting blades. 2. Move the throttle lever to between the half and full throttle position. 3. Turn the ignition key to Off and remove the key.
Driving Using the Smart SpeedTM Control System Driving the machine benefits from an understanding of what zero-turn-radius mower means. The drive wheels turn independently, powered by hydraulic motors on each axle; hence one side can turn in reverse while the other turns forward causing the machine to spin rather than turn. This vastly improves the machine maneuverability but may require some adjustment if the operator is unfamiliar.
• Bagging Driving Backward • Mulching Note: Always use caution when backing up and turning. Mow 1. Move the levers to the center, unlocked position. This is the fastest speed. The suggested uses for this speed are as follows: 2. To go backward, look behind you and down, as you slowly pull the motion-control levers rearward (Figure 16). • Normal mowing • Transporting the machine Driving Forward Note: Always use caution when backing up and turning. 1.

Electrical System Maintenance WARNING CALIFORNIA Proposition 65 Warning Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. A B Charging the Battery Removing the Battery WARNING C Battery terminals or metal tools could short against metal machine components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.
Charging the Battery WARNING Service Interval: Before storage—Charge the battery and disconnect battery cables. Incorrect battery-cable routing could damage the machine and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. 1. Remove the battery from the chassis; refer to Removing the Battery (page 29). • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable. 2.
Servicing the Fuses Drive System Maintenance The electrical system is protected by fuses. It requires no maintenance; however, if a fuse blows, check the component/circuit for a malfunction or short. Fuse type: Checking the Tire Pressure • Main—F1-30 amp, blade-type Service Interval: Every 25 hours—Check tire pressure. • Charge Circuit—F2-25 amp, blade-type Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut.
Releasing the Electric Brake Mower Maintenance The electric brake releases by manually rotating the link arms forward. Once the electric brake is energized the brake will reset. Servicing the Cutting Blades Maintain sharp blades throughout the cutting season, because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth, and increases the chance of disease.

Blade A. If the difference between A and B is greater than 3mm (1/8 inch), replace the blade with a new blade; refer to Removing the Blades (page 34) and Installing the Blades (page 34). Sharpening the Blades 1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 46).
Important: The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting. 5. Measure between the outside cutting edges and the flat surface (Figure 48). If both measurements are not within 5 mm (3/16 inch), an adjustment is required; continue with this procedure. 2. Install the curved washer (cupped side toward the blade) and the blade bolt (Figure 45). 6. Move to the left side of the machine. 3. Torque the blade bolt to 47 to 88 N-m (35 to 65 ft-lb). 7.
Note: Check and adjust the side-to-side blade level if you have not checked the setting; refer to Leveling from Side to Side (page 35). 9. After adjustment, check the front-to-rear slope again, continue adjusting the nut until the front blade tip is 1.6 to 7.9 mm (1/16 to 5/16 inch) lower than the rear blade tip (Figure 50). 4. Carefully rotate the blades so they are facing front to rear (Figure 50). 2 10.
Replacing the Grass Deflector Service Interval: Before each use or daily—Inspect the grass deflector for damage. WARNING 2 An uncovered discharge opening could allow the lawn mower to throw objects in the operator's or bystander's direction and result in serious injury. Also, contact with the blade could occur. 2 3 Never operate the machine without the grass deflector, the discharge cover, or the grass-collection system in place. 1 G005077 Inspect the grass deflector for damage before each use.
