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 Parking Brake • The stopping distance may increase with the weight of a towed load. Travel slowly and allow extra distance to stop. To disengage the parking brake, pull the lever out of the detent slot and toward you, then push it down (Figure 24). • Make wide turns to keep the attachment clear of the machine. Entering the Operator’s Position Use the mower deck as a step to get into the operator’s position (Figure 22). g188777 Figure 24 1.
Disengaging the Blade-Control Switch (PTO) g009174 Figure 27 Operating the Throttle g295540 Figure 29 You can move the throttle control between the FAST and SLOW positions (Figure 28). 1. ON position 2. OFF position Always use the FAST position when engaging the PTO. Operating the Key Switch 1. Turn the key to the START position (Figure 30). Note: When the engine starts, release the key. Important: Do not engage the starter motor for more than 5 seconds at a time.
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 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.
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. 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.
2. 3. Alternating the Mowing Direction Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization. Adjust the anti-scalp rollers as shown in Figure 36. Mowing at Correct Intervals Grass grows at different rates at different times of the year.
After Operation After Operation Safety General Safety • Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operator’s position. Allow the machine to cool before servicing, adjusting, fueling, cleaning, or storing it. • Clean grass and debris from the cutting unit, g298692 muffler, drives, grass catcher, and engine compartment to help prevent fires. Clean up oil or fuel spills. Figure 37 1.
