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 6). 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 5). 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 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 9). 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 11 g027249 Figure 9 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 12 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 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) g008945 g296056 Figure 14 Figure 17 Note: Always engage the blades with the throttle in the FAST position (Figure 15).
Starting the Engine Shutting Off the Engine 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. Note: It may be necessary to hold the lever against the stop, in the choke position, while trying to start the engine (Figure 19). 1.
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 some time for you to adapt to how it moves. Note: Always use caution when backing up and turning. 1. Move the levers to the center, unlocked position. 2.
Using the Smart SpeedTM Control System Trim The Smart Speed TM Control-System lever, located below the operating position (Figure 23), gives the operator a choice to drive the machine at 3 ground speed ranges—trim, tow, and mow. • Parking This is the lowest speed. The suggested uses for this speed are as follows: • Heavy, wet grass mowing conditions • Training • Trimming grass Tow This is the medium speed.
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).
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. After Operation Safety General Safety • Shut off the engine, remove the key, and wait Keeping the Underside of the Mower Deck Clean for all moving parts to stop before leaving the operator’s position.
Pushing the Machine by Hand 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. 1. Park the machine on a level surface, disengage the blade-control switch, and move the motion-control levers outward to the PARK position. 2. Shut off the engine and wait for all moving parts to stop before leaving the operating position. 3.
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 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 27). 4. Back the machine up the ramp (Figure 28). g027995 Figure 28 1. Back the machine up the ramp. 2. Drive the machine forward down the ramp. 5.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
