During Operation During Operation Safety General Safety • The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage. • Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur. • Do not operate the machine while ill, tired, or under the influence of alcohol or drugs. • Contacting the blade can result in serious personal injury.
• Operate the engine only in well-ventilated areas. • • • • • safely operating the machine. Children who have been given rides in the past could appear in the operating area without warning and be run over or backed over by the machine. Exhaust gases contain carbon monoxide, which is lethal if inhaled. Never leave a running machine unattended. Attach towed equipment to the machine only at the hitch point.
Entering the Operator’s Position operating on slopes can cause the machine to become unstable. Use the mower deck as a step to get into the operator’s position (Figure 23). g229111 Figure 22 1. Safe Zone—use the machine here on slopes less than 15° or flat areas. 2. Danger Zone—use a walk-behind mower and/or a hand trimmer on slopes greater than 15° and near drop-offs or water. 4. W = Width of the machine g029797 Figure 23 5.
Disengaging the Blade-Control Switch (PTO) Disengaging the Parking Brake To disengage the parking brake, pull the lever out of the detent slot and toward you, then push it down (Figure 25). g009174 Figure 28 g188777 Figure 25 1. Push the parking brake out of the detent slot and toward you. Operating the Throttle 2. Push the parking brake down. You can move the throttle control between the FAST and SLOW positions (Figure 29). Always use the FAST position when engaging the PTO.
Operating the Choke Operating the Key Switch 1. Use the choke to start a cold engine. 1. Pull up the choke knob to engage the choke before using the key switch (Figure 30). 2. Push down the choke knob to disengage the choke after the engine has started (Figure 30). Turn the key to the START position (Figure 31). Note: When the engine starts, release the key. Important: Do not engage the starter motor for more than 5 seconds at a time. If the engine fails to start, wait 10 seconds between attempts.
Starting the Engine Shutting Off the Engine 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. 1. Disengage the blades by moving the blade-control switch to the OFF position. 2. Engage the parking brake. 3.
Driving the Machine 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. The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance.
Adjusting the Height of Cut The machine is equipped with a foot pedal deck-lift system. You can use the foot pedal to lift the deck briefly to avoid obstacles and to raise the deck. You can adjust the height of cut from 38 to 114 mm (1-1/2 to 4-1/2 inches) in 6 mm (1/4 inch) increments by moving the height-of-cut pin into different hole locations. g008953 Figure 35 1. Push on the deck-lift pedal with your foot to raise the mower deck. 2.
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.
Transporting the Machine WARNING Contact with hot surfaces may cause personal injury. 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 39). 4. Back the machine up the ramp (Figure 40). g027995 Figure 40 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.
