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 5). Control Panel Park Position Move the motion-control levers outward from the center to the PARK position when exiting the machine (Figure 18). 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 22). 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 Motion-Control Levers 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). Adjusting the Height You can adjust the motion-control levers higher or lower for maximum comfort (Figure 10). g027252 Figure 10 Adjusting the Tilt g027249 Figure 9 You can adjust the motion-control levers forward or rearward for your comfort. 14 1.
During Operation – Shut off the engine and remove the key. – Wait for all moving parts to stop. • Operate the engine only in well-ventilated areas. During Operation Safety Exhaust gases contain carbon monoxide, which is lethal if inhaled. General Safety • Never leave a running machine unattended. • Attach towed equipment to the machine only at • The owner/operator can prevent and is responsible • • • • • • • • • • • • for accidents that may cause personal injury or property damage.
• Keep children out of the operating area and under • Remove or mark obstacles such as ditches, holes, the watchful care of a responsible adult other than the operator. 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. Follow directions for counterweights.
Disengaging the Blade-Control Switch (PTO) • The stopping distance may increase with the weight of a towed load. Travel slowly and allow extra distance to stop. • Make wide turns to keep the attachment clear of the machine. Operating the Mower Blade-Control Switch (PTO) g009174 The blade-control switch (PTO) starts and stops the mower blades and any powered attachments.
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 17). 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 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 20).
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 22. 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 22).
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.
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 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 25). 4. Back the machine up the ramp (Figure 26). g027995 Figure 26 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.
