Park Position Height-of-Cut Lever Move the motion-control levers outward from the center to the PARK position when exiting the machine (Figure 17). 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 Pre-Start Note: Determine the left and right sides of the Fill fuel tank on level ground. See Fuel Recommendations in the Specifications section for additional gasoline information. machine from the normal operating position. Do Not add oil to gasoline. Before Operation Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.
Fuel Safety DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors. A fire or explosion from gasoline can burn you and others and cause property damage. • Always place gasoline containers on the ground away from your vehicle before filling.
Adding Fuel Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel to expand. Recommended Fuel • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use.
Using the Safety-Interlock System motion-control levers to the center, unlocked position, engage the blade-control switch, and rise slightly from the seat; the engine should shut off. WARNING Positioning the Seat If the safety-interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury. The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 8).
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 9). The operator must use their full attention when operating the machine. Do Not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

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 19). Suggested uses: Trim Parking X Heavy, wet grass X Training X Trimming grass X Tow Bagging X Mulching X Towing attachments X Mow Normal mowing X Moving the machine X g008953 Figure 19 Trim This is the lowest speed.
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. 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 21. Height of cut is controlled by the lever located to the right of the operating position (Figure 21).
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.
