Ignition Switch Product Overview The ignition switch has three positions, Off, Run and Start. The key moves from the Start position to the Run position when you release it. Turn the key to the Off position to shut off the engine; however, always remove the key from the ignition switch when leaving the machine to prevent someone from accidentally starting the engine (Figure 5). Throttle/Choke Control The throttle and choke is combined into one control lever.
Fuel Window Operation The fuel window located on the left hand side of the machine can be used to verify the presence of gasoline in the tank (Figure 7). Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel G014521 • 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).
Filling the Fuel Tank DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Note: Ensure that the engine is shut off and the motion-controls are in the parked position. Note: You can use the fuel window to verify the presence of gasoline before filling the tank (Figure 8). Important: Do not overfill fuel tank.
Think Safety First CAUTION This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Operating Safety Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets or bystanders avoid injury. Wear hearing protection when operating this machine.
4. Move either motion-control lever to the center, unlocked position. A B C D 5. Try starting the engine; the engine should not crank. 6. Repeat with the other motion-control lever. 7. While sitting on the seat, move the blade-control switch to Off, and lock the motion-control levers in the park position. 8. Start the engine. 9. While the engine is running, engage the blade-control switch, and rise slightly from the seat. Note: The engine should stop. 10.
Operating the Blades Driving the Machine The blade-control switch, represented by a power take-off (PTO) symbol, engages and disengages power to the mower blades. This switch controls power to any attachments that draw power from the engine, including the mower deck and cutting blades. Driving the machine benefits from an understanding of what zero-turn-radius mower means.
Using the Smart SpeedTM Control System • Bagging • Mulching TM The Smart Speed Control-System lever, located below the operating position (Figure 15), gives the operator a choice to drive the machine at 3 ground speed ranges—trim, tow, and mow. Mow This is the fastest speed. The suggested uses for this speed are as follows: • Normal mowing • Transporting the machine Driving Forward 1. Move the levers to the center, unlocked position. 2.
Driving Backward Adjusting the Height-of-Cut Note: Always use caution when backing up and turning. Note: The transport position is the highest height-of-cut position or cutting height (115 mm (4.5 inches)) as shown in Figure 18. 1. Move the levers to the center, unlocked position. 2. To go backward, look behind you and down, as you slowly pull the motion-control levers rearward (Figure 17). G008953 Figure 17 To go straight, apply equal pressure to both motion-control levers (Figure 17).
Adjusting the Motion-Control Levers • Upper hole—use this position with the mower deck in the 63mm (2-1/2 inch) and below height-of-cut positions (Figure 19). • Lower hole—use this position with the mower Adjusting the Height deck in the 76mm (3 inch) and above height-of-cut positions (Figure 19). The motion-control levers can be adjusted higher or lower for maximum operator comfort (Figure 21). 4 A B 3 2 g019929 1 5 Figure 19 1. Anti-scalp roller 4.
Grass Deflector 5. Move the motion-control levers inward to the neutral position and turn the ignition key to the run position. Do not start the machine. The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. The machine is now able to be pushed by hand. 3 DANGER Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris.
WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death. • Use extreme caution when operating a machine on a ramp. • Use only a full-width ramp; do not use individual ramps for each side of the machine. Figure 23 • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.
Operating Tips 1 Fast Throttle Setting 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 by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.
Long Grass If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. When Stopping If the machine's forward motion must be stopped while mowing, a clump of grass clippings may drop onto your lawn.
