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 to engage the electric brake (Figure 22). Always position the motion-control levers into the PARK position when you stop the machine or leave it unattended.
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 and 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 MyRide® Suspension System 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 You can adjust the MyRide® suspension system for a smooth and comfortable ride. The slots for adjusting the suspension have detent positions for reference, ranging from a soft to a firm ride (Figure 11). g027632 Figure 9 Machines with MyRide 1.
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 owner/operator can prevent and is responsible • • • g333847 Figure 12 • 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.
• Before backing up or turning the machine, look – Shut off the engine and remove the key. down and all around for small children. – Wait for all moving parts to stop. • Do not carry children on the machine, even when • Operate the engine only in well-ventilated areas. the blades are not moving. Children could fall off and be seriously injured or prevent you from safely operating the machine.
Operating the Mower Blade-Control Switch (PTO) • 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. Follow directions for counterweights. 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 Throttle Starting the Engine You can move the throttle control between the FAST and SLOW positions (Figure 19). 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 (Figure 18). 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. 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.
Driving Backward To change speeds, do the following: Note: Always use caution when backing up and 1. Move the motion-control levers to neutral and outward to the PARK position. turning. 1. Move the levers to the center, unlocked position. 2. Disengage the blade-control switch. 2. To go backward, slowly pull the motion-control levers rearward (Figure 24). 3. Adjust the lever to the desired position. The following are only recommendations for use.
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 26. 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 26).
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 29). 4. Back the machine up the ramp (Figure 30). g027995 Figure 30 1.
