Controls Motion-Control Levers Become familiar with all the controls before you start the engine and operate the machine. Use the motion-control levers to drive the machine forward, reverse, and turn either direction (Figure 4). Control Panel Park Position Move the motion-control levers outward from the center to the PARK position when exiting the machine to engage the electric brake (Figure 19).
Height-of-Cut Lever Operation Use the height-of-cut lever to lower and raise the deck from the seated position. Moving the lever up (toward you) raises the deck from the ground and moving the lever down (away from you) lowers the deck toward the ground. Adjust the height-of-cut only while the machine is not moving (Figure 23). Note: Determine the left and right sides of the machine from the normal operating position.
Fuel Safety compartment to help prevent fires. Clean up oil or fuel spills. • Fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. Adding Fuel – To prevent a static charge from igniting the fuel, place the container and/or machine directly on the ground before filling, not in a vehicle or on an object. Recommended Fuel – Fill the fuel tank outdoors on level ground, in an open area, and when the engine is cold.
Understanding the Safety-Interlock System The safety-interlock system is designed to prevent the engine from starting unless: • The blade-control switch (PTO) is disengaged. • The motion-control levers are in the PARK position. The safety-interlock system also is designed to shut off the engine whenever the control levers are out of the PARK position and you rise from the seat. Testing the Safety-Interlock System Test the safety-interlock system before you use the machine each time.
Positioning the Seat Adjusting the Tilt The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 8). You can adjust the motion-control levers forward or rearward for your comfort. 1. Loosen the upper bolt holding the control lever to the control-arm shaft. 2. Loosen the lower bolt just enough to pivot the control lever forward or rearward. g333846 Figure 10 g027249 Figure 8 3.
• Operate the machine only in good visibility and appropriate weather conditions. Do not operate the machine when there is the risk of lightning. • Keep your hands and feet away from the cutting units. Keep clear of the discharge opening. • Do not mow with the discharge deflector g229846 Figure 11 raised, removed, or altered unless there is a grass-collection system or mulch kit in place and working properly. 1. Wear hearing protection.
– Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope. • Identify hazards at the base of the slope. Do not operate the machine near drop-offs, ditches, embankments, water, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses.
Operating the Mower Operating the Throttle Blade-Control Switch (PTO) You can move the throttle control between the FAST and SLOW positions (Figure 16). The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. Always use the FAST position when engaging the PTO. Engaging the Blade-Control Switch (PTO) g295539 Figure 16 g008945 Figure 13 Note: Always engage the blades with the throttle in Operating the Choke the FAST position (Figure 14).
Starting the Engine CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. Note: A warm or hot engine may not require choking. 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.
Driving the Machine Driving Backward The drive wheels turn independently, powered by hydraulic motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require sometime for you to adapt to how it moves. 1. Move the levers to the center, unlocked position. 2. To go backward, slowly pull the motion-control levers rearward (Figure 21).
2. Disengage the blade-control switch. 3. Adjust the lever to the desired position. Using the Side Discharge The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass.
Adjusting the Height of Cut Adjusting the Anti-Scalp Rollers Note: The transport position is the highest height-of-cut position or cutting height at 114 mm (4-1/2 inches) as shown in Figure 23. Whenever you change the height of cut, adjust the height of the anti-scalp rollers. You can adjust the height of cut from 38 to 114 mm (1-1/2 to 4-1/2 inches) in 13 mm (1/2 inch) increments. The height of cut is controlled by the lever located to the right of the operating position (Figure 23).
Operating Tips drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or you can disengage the mower deck while moving forward. Using the Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the FAST position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower deck in uncut grass.
After Operation 5. After Operation Safety Turn the ignition key on and disengage the parking brake by moving 1 motion-control lever out of the PARK position. Note: Do not start the machine. General Safety • Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operator’s position. Allow the machine to cool before servicing, adjusting, fueling, cleaning, or storing it.
Transporting the Machine Use a heavy-duty trailer or truck to transport the machine. Use a full-width ramp. Ensure that the trailer or truck has all the necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you or bystanders avoid injury. Refer to your local ordinances for trailer and tie-down requirements.
1. If using a trailer, connect it to the towing vehicle and connect the safety chains. 2. If applicable, connect the trailer brakes and lights. 3. Lower the ramp, ensuring that the angle between the ramp and the ground does not exceed 15 degrees (Figure 26). 4. Back the machine up the ramp (Figure 27). g027995 Figure 27 1. Back the machine up the ramp. 2. Drive the machine forward down the ramp. 5. Shut off the engine, remove the key, and engage the parking brake. 6.
