Adding Fuel Fuel Safety • Fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. Recommended Fuel – To prevent a static charge from igniting the fuel, remove the machine from the truck or trailer and refuel it on the ground, away from all vehicles.
Using the Safety-Interlock System WARNING If the 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. 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.
4. 5. Adjusting the MyRide™ Suspension System Sit on the seat, engage the parking brake, move the blade-control switch (PTO) to the OFF position, and move the motion-control levers to NEUTRAL-LOCK position. Start the engine. While the engine is running, center either motion-control lever and move it forward or reverse; the engine should shut off. Repeat for other motion-control lever. Machines with MyRide Only The MyRide™ suspension system adjusts to provide a smooth and comfortable ride.
Adjusting the Motion-Control Levers Adjusting the Height You can adjust the motion-control levers higher or lower for maximum comfort (Figure 11). g335104 g333847 Figure 11 Adjusting the Tilt 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. g195745 Figure 10 g333846 Figure 12 18 3.

and cause a loss of control. Follow directions for counterweights. off and be seriously injured or prevent you from safely operating the machine. Children who have been given rides in the past could appear in the operating area without warning and be run over or backed over by the machine. • If possible, keep the deck lowered to the ground while operating on slopes. Raising the deck while operating on slopes can cause the machine to become unstable.
Operating the Parking Brake Engaging the Blade-Control Switch (PTO) Always engage the parking brake when you stop the machine or leave it unattended. Engaging the Parking Brake Park the machine on a level surface. g008945 Figure 17 Note: Always engage the blades with the throttle in the FAST position (Figure 18). g188778 Figure 15 1. Pull the parking brake up.
Operating the Throttle Operating the Key Switch 1. You can move the throttle control between the FAST and SLOW positions (Figure 20). Turn the key to the START position (Figure 22). Note: When the engine starts, release the key. Always use the FAST position when engaging the PTO. Important: Do not engage the starter motor for more than 5 seconds at a time. If the engine fails to start, wait 10 seconds between attempts. Failure to follow these instructions can burn out the starter motor.
Starting the Engine Shutting Off the Engine 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. 1. Disengage the blades by moving the blade-control switch to the OFF position. 2. Engage the parking brake. 3.
Driving the Machine 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 some time for you to adapt to how it moves. The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance.
Adjusting the Height of Cut The machine is equipped with a foot pedal deck-lift system. You can use the foot pedal to lift the deck briefly to avoid obstacles and to raise the deck. You can adjust the height of cut from 38 to 114 mm (1-1/2 to 4-1/2 inches) in 6 mm (1/4 inch) increments by moving the height-of-cut pin into different hole locations. g008953 Figure 26 1. Push on the deck-lift pedal with your foot to raise the mower deck. 2.
Adjusting the Anti-Scalp Rollers Operating Tips Maximizing Air Circulation Whenever you change the height of cut, adjust the height of the anti-scalp rollers. 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. Always try to have 1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower deck.
Stopping the Machine After Operation If you must stop the forward motion of the machine while mowing, a clump of grass clippings may 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.
Transporting the Machine WARNING Contact with hot surfaces may cause personal injury. 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 you are 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 30). 4. Back the machine up the ramp (Figure 31). g027995 Figure 31 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.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Maintenance Safety • If you leave the key in the switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the switch before you perform any maintenance. • Before you leave the operator’s position, do the following: – Park the machine on a level surface. – Disengage the drives. – Engage the parking brake. – Shut off the engine and remove the key.
Recommended Maintenance Schedule(s) Maintenance Service Interval Before each use or daily Maintenance Procedure • • • • Check the safety-interlock system. Check the engine-oil level. Inspect the blades. Inspect the grass deflector for damage. After each use • Clean grass and debris from the cutting unit, muffler, drives, grass catcher, and engine. Every 25 hours • Clean the air-cleaner foam element (more often in dusty, dirty conditions). • Check tire pressure. • Check the belts for wear or cracks.
