Move the motion-control levers outward from the center to the PARK position when exiting the machine (Figure 20). Always position the motion-control levers into the PARK position when you stop the machine or leave it unattended. Control Panel MyRide™ Adjustment Lever For Machines with the MyRide™ Suspension System Use the MyRide™ adjustment lever to adjust the seat suspension (Figure 4).
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 24). Note: Determine the left and right sides of the machine from the normal operating position.
Pre-Start Fuel Safety Fill fuel tank on level ground. See Fuel Recommendations in the Specifications section for additional gasoline information. Use extreme care when handling fuel. Do Not add oil to gasoline. In certain conditions gasoline is extremely flammable and vapors are explosive. DANGER Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand.
flame or any enclosed area where open pilot lights or heat appliances are present. DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors. A fire or explosion from gasoline can burn you and others and cause property damage. Adding Fuel • Always place gasoline containers on the ground away from your vehicle before filling.
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.
Adjusting the MyRide™ Suspension System Positioning the Seat The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 9 or Figure 10). Machines with MyRide Only The MyRide™ suspension system adjusts to provide a smooth and comfortable ride. Position the suspension system where you are most comfortable. The slots for the suspension adjustment have detent positions for reference.
Adjusting the Motion-Control Levers During Operation During Operation Safety Adjusting the Height General Safety You can adjust the motion-control levers higher or lower for maximum comfort (Figure 12). The operator must use their full attention when operating the machine. Do Not engage in any activity that causes distractions; otherwise, injury or property damage may occur. WARNING Operating engine parts, especially the muffler, become extremely hot.
• Be sure all drives are in neutral and parking brake • • • • is engaged before starting engine. Start the engine carefully according to instructions with feet well away from the blades. Never operate the mower with damaged guards, shields, or covers. Always have safety shields, guards, switches and other devices in place and in proper working condition. Keep clear of the discharge opening at all times.
Towing Safety distance (twice the width of the machine) between the machine and any hazard. Use a walk behind machine or a hand trimmer to mow the grass in these areas. • Do not attach towed equipment except at the hitch point. • Do not use the machine as a towing vehicle unless it has a hitch installed. • Do not exceed the weight limits for towed equipment and towing on slopes. The towed weight must not exceed the weight of the machine and operator.
Operating the Mower Operating the Throttle Blade-Control Switch (PTO) You can move the throttle control between the FAST and SLOW positions (Figure 17). 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 17 g008945 Figure 14 Note: Always engage the blades with the throttle in Operating the Choke the FAST position (Figure 15).
Starting the Engine Shutting Off the Engine Note: A warm or hot engine may not require choking. 1. Disengage the blades by moving the blade-control switch to the OFF position (Figure 16). 2. Move the motion-control levers outward to the PARK position. 3. Move the throttle lever to the SLOW position and let the engine idle for 1 minute. 4. Turn the key to the OFF position and remove the key. Important: Do not engage the starter for more than 5 seconds at a time.
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 22).
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 24. 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 24).
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 WARNING Driving on the street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury. After Operation Safety General Safety • Park machine on level ground, disengage drives, • • Do not drive machine on a public street or roadway. set parking brake, stop engine, remove key or disconnect spark plug wire.
WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death. • Use extreme caution when operating a machine on a ramp. • Use only a full-width ramp; do not use individual ramps for each side of the machine. • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck. • Ensure the length of ramp is at least four times (4X) as long as the height of the trailer or truck bed to the ground.
