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. • Always place gasoline containers on the ground away from your vehicle before filling.
3. Install the fuel-tank cap securely, and tighten until it clicks. Checking the Engine-oil Level Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-oil Level (page 24). Breaking In a New Machine New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine.
Understanding the Safety-interlock System WARNING If safety-interlock switches are disconnected or damaged, the machine could operate unexpectedly causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily, and replace any damaged switches before operating the machine. The safety-interlock system is designed to prevent the engine from starting unless: • The blades are disengaged. • The motion-control levers are in the park position.

After the engine starts, push down on the Choke control (Figure 13).
Driving Testing the Safety-interlock 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. Test the safety-interlock system before you use the machine each time.
Driving Forward Using the Smart Speed™ Control System 1. Move the levers to the center, unlocked position. The Smart Speed™ Control-System lever, located below the operating position (Figure 17), gives the operator a choice to drive the machine at 2 ground speed ranges—high and low. 2. To go forward, slowly push the motion-control levers forward (Figure 16). 1 G014475 Figure 17 1. Smart-speed lever To change speeds: G008952 Figure 18 1.
Driving Backward Adjusting the Height-of-Cut 1. Move the levers to the center, unlocked position. Height-of-cut is controlled by the lever located to the right of the operating position (Figure 20). 2. To go backward, look behind you and down, as you slowly pull the motion-control levers rearward (Figure 19). 1. Pull up and inward on the lever to move it to the desired cutting position. 2. Once at the desired cutting position, slowly lower the lever until it engages the position.
Adjusting the Motion-control Levers • Upper hole—use this position with the mower deck in the 63 mm (2-1/2 inches) and below the height-of-cut positions (Figure 21). • Lower hole—use this position with the mower Adjusting the Height deck in the 76 mm (3 inches) and above the height-of-cut positions (Figure 21). The motion-control levers can be adjusted higher or lower for maximum operator comfort. 4 1. Remove the 2 bolts holding the control lever to the control-arm shaft (Figure 23). 2.
Pushing the Machine 1. Park the machine on a level surface, and disengage the blade-control switch. 2. Move the motion-control levers outward to the park position, stop the engine, and wait for all moving parts to stop before leaving the operating position. 3. Locate the bypass levers on the frame on both sides of the engine. 4. Move the bypass levers forward through the key hole and down to lock them in place (Figure 24). Note: Ensure this is done for each lever. 5.
Cutting Long Grass Operating Tips If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. Using the Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the Fast throttle position.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Before each use or daily Maintenance Procedure • • • • • Check the safety-interlock system.

Fuel System Maintenance 2 1 DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. G008794 Figure 33 • Perform any fuel related maintenance when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills. Installing the Spark Plug 1. Install the spark plug.
Electrical System Maintenance 4. Squeeze the ends of the hose clamps together and slide them away from the filter (Figure 34). 5. Remove the filter from the fuel lines. 6. Install a new filter with the flow direction arrow coming from the fuel tank and pointing to the engine. WARNING 7. Move the hose clamps close to the filter (Figure 34) to secure it in place.
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 28). • 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. To release the brake: 1.
