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 20).
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 4). Note: Determine the left and right sides of the machine from the normal operating position.
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.
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 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). g292102 Figure 9 1. MyRide adjustment lever 3. Firmer suspension 2. Softer suspension g027632 Adjusting the Motion-Control Levers Figure 8 Adjusting the MyRide® Suspension System Adjusting the Height You can adjust the motion-control levers higher or lower for maximum comfort (Figure 10).
• Do not mow in reverse unless it is absolutely necessary. Always look down and behind you before moving the machine in reverse. • Use extreme care when approaching blind corners, shrubs, trees, or other objects that may block your view. • Stop the blades whenever you are not mowing. • If the machine strikes an object or starts to vibrate, immediately shut off the engine, remove the key (if equipped), and wait for all moving parts to stop before examining the machine for damage.
• Clean grass and debris from the cutting unit, • • • • • • • • • machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe 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. drives, muffler, and engine to help prevent fires. Start the engine with your feet well away from the blades. Be aware of the mower discharge path and direct the discharge away from others.
Towing Safety Operating the Mower Blade-Control Switch (PTO) • Do not attach towed equipment except at the hitch point. The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. • Do not use the machine as a towing vehicle unless it has a hitch installed. • Do not exceed the weight limits for towed Engaging the Blade-Control Switch (PTO) equipment and towing on slopes. The towed weight must not exceed the weight of the machine and operator.
Operating the Throttle Starting the Engine You can move the throttle control between the FAST and SLOW positions (Figure 17). Note: A warm or hot engine may not require choking. Always use the FAST position when engaging the PTO. 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 Shutting Off the Engine 1. Disengage the blades by moving the blade-control switch to the OFF position. 2. Move the motion-control levers outward to the PARK position. 3. Move the throttle control to between the half and full throttle position. 4. Turn the key to the OFF position and remove the key. The drive wheels turn independently, powered by hydraulic motors on each axle.
Driving Backward 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. The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass.
Using the Side Discharge Adjusting the Height of Cut The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 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. 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).
Machines with 127 cm (50-inch) or 137 cm (54-inch) Mower Decks Adjusting the Anti-Scalp Rollers Whenever you change the height of cut, adjust the height of the anti-scalp rollers. Machines with 107 cm (42-inch) Mower Decks Note: Adjust the anti-scalp rollers so that the rollers do not touch the ground in normal, flat mowing areas. Whenever you change the height of cut, adjust the height of the anti-scalp rollers. 1.
Stopping the Machine Operating Tips 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. Maximizing Air Circulation For best mowing and maximum air circulation, operate the engine at the FAST position.
