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 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). 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.
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 10). • The owner/operator can prevent and is responsible • • • • g027252 Figure 10 • • 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 leaving the operating position (including quickly affect the operation of the machine on a slope. to empty the catchers or to unclog the chute), do the following: • Identify hazards at the base of the slope. Do – Stop the machine on level ground. 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 Blade-Control Switch (PTO) The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. Engaging the Blade-Control Switch (PTO) g229111 Figure 12 1. Safe Zone—use the machine here on slopes less than 15 degrees or flat areas. 2. Danger Zone—use a walk-behind mower and/or a hand trimmer on slopes greater than 15 degrees and near drop-offs or water. 3. Water 4. W=width of the machine g008945 Figure 13 5.
Operating the Throttle Starting the Engine You can move the throttle control between FAST and SLOW positions (Figure 16). 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. Always use the FAST position when engaging the PTO.
4. Driving the Machine Turn the key to the OFF position and remove the key. 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. CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
2. The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass. To go backward, slowly pull the motion-control levers rearward (Figure 20). Suggested uses: Trim Parking X Heavy, wet grass X Training X Tow Bagging X Mulching X Mow Normal mowing X Transport X Trim This is the lowest speed.
Tow Adjusting the Height of Cut This is the medium speed. The suggested uses for this speed are as follows: 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. • Bagging • Mulching Height of cut is controlled by the lever located to the right of the operating position (Figure 22). Mow This is the fastest speed.
Adjusting the Anti-Scalp Rollers Operating Tips Using the Fast Throttle Setting For Machine with 107 cm (42-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 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.
