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 Height-of-Cut Lever The height-of-cut lever allows you to lower and raise the deck from the seated position. When you raise the lever (toward you), the deck is raised from the ground, and when you lower it (away from you), it lowers to the ground. Adjust the height-of-cut only while the machine is not moving. Refer to Adjusting the Height-of-Cut (page 21). The motion-control levers are speed-sensitive controls of independent-wheel motors.
Operation 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.
Think Safety First of varnish deposits in the fuel system, use fuel stabilizer at all times. Operating Safety Filling the Fuel Tank 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. Note: Ensure that the engine is shut off and the motion controls are in the parked position. Note: You can use the fuel window to verify the presence of gasoline before filling the tank (Figure 8).
Understanding the Safety-Interlock System 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. 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.
Starting the Engine Engaging the Blades 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. Important: Do not engage the blades when parked in tall grass. Belt or clutch damage can occur. Note: Always engage the blades with the throttle in the Fast position.
Driving the Machine 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 17). • Normal mowing • Transporting the machine Driving Forward 1. Move the levers to the center, unlocked position. 2.
Adjusting the Height-of-Cut Positioning the Seat Note: The transport position is the highest height-of-cut position or cutting height 115 mm (4.5 inches) as shown in Figure 18. A B C g027249 Figure 19 Adjusting the Motion-Control Levers Adjusting the Height The motion-control levers can be adjusted higher or lower for maximum operator comfort (Figure 20). Figure 18 A B g027252 Figure 20 Adjusting the Tilt The motion-control levers can be tilted fore or aft for maximum operator comfort. 1.
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 38). 2. Loosen the lower bolt just enough to pivot the control lever fore or aft (Figure 20). Tighten both bolts to secure the control in the new position. 3. Repeat the adjustment for the opposite control lever.
G009660 5. Lift the cover out and away from the deck. 1 6. Lower the grass deflector over the discharge opening. Important: Ensure that the mower has a hinged grass deflector that disperses clippings to the side and down toward the turf, while in side discharge mode. 2 3 Installing the Discharge Cover for Mulching 1. Park the machine on a level surface and disengage the blade-control switch. 4 2.
Note: Do not overtighten the nuts; this could distort the cover and cause blade contact. 9. Lower the grass deflector over the discharge opening Important: Ensure that the mower has a hinged grass deflector that disperses clippings to the side and down toward the turf, while in side-discharge mode. 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.
Loading the Machine 1 Use extreme caution when loading or unloading machines onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Back up ramps and drive forward down ramps (Figure 27). Figure 27 1. Back up ramps 2 2. Drive forward down ramps Important: Do not use narrow individual ramps for each side of the machine. 6 Ensure the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 28).
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.

Electrical System Maintenance 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. g027506 A 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.
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 35). • 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 can be release 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.
Inspecting the Blades 3. Measure from the tip of the blade to the flat surface (Figure 50). Service Interval: Before each use or daily—Check the cutting blades. 1. Inspect the cutting edges (Figure 48). Note: If the edges are not sharp or have nicks, remove and sharpen the blades; refer to Sharpening the Blades (page 40). 1 2.
