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 25). 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 4 Adjusting the Height G010233 The motion-control levers can be adjusted higher or lower for maximum operator comfort. 3 1 1. Remove the 2 bolts holding the control lever to the control-arm shaft (Figure 23). 2 2. Move the control lever to the next set of holes. Figure 21 1. Anti-scalp roller 3. Flange nut 2. Bolt 4. Hole spacing 3. Secure the lever with the 2 bolts (Figure 23).
Pushing the Machine by Hand Operating the Machine Important: Always push the machine by hand. Do not tow the machine, because damage may occur. Move the bypass levers rearward through the key hole and down to lock them in place as shown in Figure 24. This machine has an electric-brake mechanism, and to push the machine, the ignition key needs to be in the Run position. The battery needs to be charged and functioning for the electric brake to be disengage. Note: Ensure this is done for each lever.
Cutting Long Grass Operating Tips If the grass is 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. Check the air cleaner for dirty, loose or damaged parts. Check the engine-oil level. Check the cutting blades. Inspect the grass deflector for damage After each use • Clean the mower housing. Every 25 hours • Grease all the lubrication points.
Premaintenance Procedures Lubrication Raising the Seat Service Interval: Every 25 hours—Grease all the lubrication points. Make sure that the motion-control levers are locked in the park position. Lift the seat forward. Grease Type: No. 2 general purpose, lithium-base grease 1. Park the machine on a level surface, and disengage the blade-control switch. 2.
Engine Maintenance 1 2 3 Servicing the Air Cleaner Service Interval: Before each use or daily—Check the air cleaner for dirty, loose or damaged parts. Every 50 hours—Service the paper element (more often under extremely dusty, dirty conditions). Every 100 hours—Replace the paper element (more often under extremely dusty, dirty conditions). g023919 4 This engine is equipped with a replaceable, high density paper air-cleaner element. Check the air cleaner daily or before starting the engine.
Changing the Engine Oil and the Engine-oil Filter 5. Insert the dipstick into the tube. 1 Service Interval: Every 100 hours—Change the engine oil and the engine-oil filter. Fill with oil as specified in the “Viscosity Grades” table (Figure 28). Change the engine oil and the engine-oil filter while the engine is still warm. The oil will flow more freely and carry away more impurities. Make sure that the engine is level when filling, checking, or changing the oil.
Servicing the Spark Plug 10. Locate the oil filter on the right side of the engine, and remove the old filter and wipe off the filter adapter with a clean cloth (Figure 31). Service Interval: Every 200 hours—Check spark plug(s) condition and gap. Every 500 hours—Replace the spark plug(s). The spark plug is RFI compliant. Equivalent alternate brand plugs can also be used. Type: Champion XC12YC (or equivalent) 1 Air Gap: 0.76 mm (0.03 inch) Removing the Spark Plug 1.
Checking the Spark Plug Fuel System Maintenance Important: Do not clean the spark plug(s). Always replace the spark plug(s) when it has: a black coating, worn electrodes, an oily film, or cracks. DANGER If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty. In certain conditions, gasoline is extremely flammable and highly explosive.
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 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. 1.
