Engine Controls Ignition Switch Become familiar with all controls in Figure 4 and Figure 5 before you start the engine and operate the machine.
Motion-Control Levers and Park Position Operation The motion-control levers are speed-sensitive controls of independent-wheel motors. Moving a lever forward or backward turns the wheel on the same side forward or in reverse; wheel speed is proportional to the amount the lever is moved. Move the control levers outward from the center to the PARK position when exiting the machine (Figure 13). Always position the motion-control levers into the PARK position when you stop the machine or leave it unattended.
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 operator’s ear and can cause hearing loss through extended periods of exposure. Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury. Wear hearing protection when operating this machine. DANGER Operating the machine on wet grass or steep slopes can cause sliding and loss of control.
Testing the Safety-Interlock System Starting the Engine Important: Do not engage the starter for more than 5 seconds at a time. Engaging the starter motor for more than 5 seconds can damage the starter motor. If the engine fails to start, wait 10 seconds before operating the engine starter again. Test the safety-interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately.
Driving the Machine Note: Always engage the blades with the throttle in the FAST position. 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 1 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 you are unfamiliar.
Driving Forward Driving Backward Note: Always use caution when backing up and turning. Note: Always use caution when backing up and turning. 1. Move the levers to the center, unlocked position. 1. Move the levers to the center, unlocked position. 2. To go forward, slowly push the motion-control levers forward (Figure 14). 2. To go backward, look behind you and down, as you slowly pull the motion-control levers rearward (Figure 15).
To change speeds, do the following: WARNING 1. Move the motion-control levers to the NEUTRAL position and outward to the PARK position. Children or bystanders may be injured if they move or attempt to operate the mower while it is unattended. 2. Disengage the blade-control switch. 3. Adjust the lever to the desired position. Always remove the ignition key and move the motion-control levers outward to the PARK position when leaving the machine unattended, even if just for a few minutes.
Positioning the Seat 2. Loosen the lower bolt just enough to pivot the control lever forward or rearward (Figure 19). Move the seat forward or backward as shown in Figure 18. A 3. Tighten both bolts to secure the control lever in the new position. B 4. Repeat the adjustment for the other control lever. Pushing the Machine by Hand Important: Always push the machine by hand. Do not tow the machine, because damage may occur.
6. When finished, ensure that the key has been returned to the STOP position to avoid draining the battery charge. 4. Remove the hinge pin securing the cover to the deck (Figure 21). Note: If the machine fails to move, the electric brake may still be engaged. If necessary, the electric brake can be released manually; refer to Releasing the Electric Brake (page 36). 5. Lift the cover out and away from the deck. 6. Lower the grass deflector over the discharge opening.
Converting to Side Discharge For Models with 107 cm (42-inch) Mower Decks The mower deck and mower blades shipped with this machine were designed for optimum mulching and side-discharge performance. 1 Removing the Discharge Cover for the Side Discharge 2 3 1. Park the machine on a level surface and disengage the blade-control switch. G005667 Figure 23 2.
Transporting the Machine Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.
Important: Do not use narrow individual ramps for each side of the machine. 1 Ensure the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 27). On flat ground, this requires a ramp to be at least 4 times as long as the height of the trailer or truck bed to the ground. A steeper angle may cause mower components to get caught as the unit moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control.
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 position.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 5 hours • Change the engine oil and filter. Before each use or daily • • • • • • Check the safety-interlock system. Clean and check the air-cleaner foam element. Check the engine-oil level. Check the air intake and cooling areas, and clean as necessary. Check the cutting blades.
Premaintenance Procedures Lubrication Raising the Seat Service Interval: Every 25 hours—Grease all lubrication points. Make sure that the motion-control levers are locked in the PARK position, and lift the seat forward. Grease Type: No. 2 general purpose, lithium grease Greasing the Bearings 1.

D Type: Champion® RC12YC, Autolite® 3924, or NGK® BCPR6ES Air Gap: 0.76 mm (0.
Checking the Spark Plug Cleaning the Blower Housing 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. To ensure proper cooling, make sure the grass screen, cooling fins, and other external surfaces of the engine are kept clean at all times. Note: 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.
Fuel System Maintenance DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you, others, and can damage property. g027506 A • Perform any fuel-related maintenance when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills. • Never smoke when draining gasoline, and stay away from an open flame or where a spark may ignite the gasoline fumes.
Electrical System Maintenance WARNING Incorrect battery-cable routing could damage the machine and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. 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. • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable.
Charging the Battery Servicing the Fuses Service Interval: Before storage—Charge the battery and disconnect battery cables. 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. 1. Remove the battery from the chassis; refer to Removing the Battery (page 34). Fuse type: 2. Charge the battery for a minimum of 1 hour at 6 to 10 amps.
Releasing the Electric Brake Drive System Maintenance The electric brake releases by manually rotating the link arms forward. Once the electric brake is energized, the brake will reset. Checking the Tire Pressure 1. Turn the ignition key to the OFF position or disconnect the battery. Service Interval: Every 25 hours—Check tire pressure. 2. Locate the shaft on the electric brake where the brake-link arms are connected (Figure 46). Maintain the air pressure in the front and rear tires as specified.
Mower Maintenance 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. Figure 47 Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary.
