Controls Park Position Become familiar with all the controls before you start the engine and operate the machine. Move the motion-control levers outward from the center to the PARK position when exiting the machine (Figure 21). 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 25). 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.
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.

Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine. Use extra care while operating with accessories or attachments, such as grass-collection systems. These can change the stability of the machine and cause a loss of control.
Operating the Mower Operating the Throttle Blade-Control Switch (PTO) You can move the throttle control between the FAST and SLOW positions (Figure 18). 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 18 g008945 Figure 15 Note: Always engage the blades with the throttle in Operating the Choke the FAST position (Figure 16).
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 17). 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 23).
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 25. 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 25).
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.
Pushing the Machine by Hand After Operation After Operation Safety Important: Always push the machine by hand. Do not tow the machine, because towing may damage it. General Safety This machine has an electric-brake mechanism, and to push the machine, the key must be in the RUN position. The battery needs to be charged and functioning to disengage the electric brake. • Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operator’s position.
Selecting a Trailer WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death (Figure 28). • 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. g295542 • Ensure that the length of the ramp is at least 4 times as long as the height of the trailer or truck bed to the ground.
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 28). 4. Back the machine up the ramp (Figure 29). g027995 Figure 29 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.
