Park Position Height-of-Cut Lever 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. 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.
Operation • Note: Determine the left and right sides of the machine from the normal operating position. Before Operation • Before Operation Safety • General Safety • Never allow children or untrained people to • • • • • • • operate or service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics. Become familiar with the safe operation of the equipment, operator controls, and safety signs.
Using Stabilizer/Conditioner Use a fuel stabilizer/conditioner in the machine to provide the following benefits: • Keeps fuel fresh during storage of 90 days or less (drain the fuel tank when storing the machine for more than 90 days) • Cleans the engine while it runs • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting Important: Do not use fuel additives containing methanol or ethanol. Add the correct amount of fuel stabilizer/conditioner to the fuel.
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 g027632 Figure 8 Test the safety-interlock system before you use the machine each time.
During Operation • Before leaving the operating position (including to empty the catchers or to unclog the chute), do the following: During Operation Safety – Stop the machine on level ground. General Safety – Disengage the power take-off and lower the attachments. • The owner/operator can prevent and is responsible – Engage the parking brake. • • • • • • • • • • • • • • • • for accidents that may cause personal injury or property damage.
• 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. 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. • Avoid starting, stopping, or turning the machine on slopes.
Operating the Mower Operating the Throttle Blade-Control Switch (PTO) You can move the throttle control between FAST and SLOW positions (Figure 15). 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) g187517 Figure 15 g008945 Figure 12 Note: Always engage the blades with the throttle in Operating the Choke the FAST position (Figure 13).
Starting the Engine CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. 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.
Driving the Machine Driving Backward 1. 2. 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. Move the levers to the center, unlocked position. To go backward, slowly pull the motion-control levers rearward (Figure 20).
Using the Side Discharge The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass. Suggested uses: Trim Parking X Heavy, wet grass X Training X Trimming grass X Tow The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.
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 115 mm (4-1/2 inches) as shown in Figure 22. For Machine with 107 cm (42-inch) Mower Decks Only Height of cut is controlled by the lever located to the right of the operating position (Figure 22). Whenever you change the height of cut, adjust the height of the anti-scalp rollers.
Adjusting the Anti-Scalp Rollers Operating Tips Using the Fast Throttle Setting For Machine with 127 cm (50-inch) Mower Decks Only 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.
After Operation 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 Keeping the Underside of the Mower Deck Clean General Safety • Clean grass and debris from the cutting units, Clean clippings and dirt from the underside of the mower deck after each use. If grass and dirt build up inside the mower deck, cutting quality will eventually become unsatisfactory.
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 26). 4. Back the machine up the ramp (Figure 27). g027995 Figure 27 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.
