Motion Control Levers and Parking Brake Position Controls Become familiar with all of the controls in and before you start the engine and operate the machine. The motion control levers are speed sensitive controls of independent wheel motors. Moving a lever forward or backward turns the wheel on the same side forward or in reverse; wheel speed is proportional to the amount the lever is moved. Move the control levers outward from the center to the park position and exit the machine ().
Height-of-Cut Lever Operation The height of cut lever allows the operator to lower and raise the deck from the seated position. When the lever is moved up, toward the operator the deck is raised from the ground and when moved down, away from the operator it is lowered toward the ground. Only adjust the height of cut while machine is not moving (). Note: Determine the left and right sides of the machine from the normal operating position.
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. • Always place gasoline containers on the ground away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.
The safety interlock system also is designed to stop the engine whenever the control levers are out of the park position and you rise from the seat. 4 2 Before Starting 1 3 Recommended Fuel • For best results, use only clean, fresh, unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). • Oxygenated fuel with up to 10% ethanol or 15% MTBE by volume is acceptable. • Do Not use ethanol blends of gasoline (such as E15 or E85) with more than 10% ethanol by volume.

1. While sitting on the seat, with the control levers in park position, and move the blade control switch to On. Try starting the engine; the engine should not crank. 2. While sitting on the seat, move the blade control switch to Off. Move either motion control lever to the center, unlocked position. Try starting the engine; the engine should not crank. Repeat with the other motion control lever. 3.
The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Placing the throttle control in the Fast position can be best for performance. For most applications, operating in the full throttle position is desirable. To change speeds: 1. Move the motion control levers to neutral and outward to the park position; disengage the blade control switch.
2. To go backward, look behind you and down as you slowly pull the motion control levers rearward (Figure 20). 3 1 2 G014476 Figure 21 G008953 1.

Grass Deflector The machine is now able to be pushed by hand. 3 The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 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. Contact with rotating mower blade(s) and thrown debris will cause injury or death.
Operating Tips 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. 3 1 1 Using the Smart SpeedTM Control System G018012 4 2 Figure 26 1. Flange nut (5/16 inch) 3. Carriage bolt (5/16 x 3/4 inch) 2.
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.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Change the engine oil.

Drive System Maintenance 2. Rotate the shaft forward to release the brake. Checking the Tire Pressure Service Interval: Every 25 hours—Check tire pressure. Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut. Check the pressure at the valve stem (). Check the tires when they are cold to get the most accurate pressure reading. Refer to the maximum pressure suggested by the tire manufacturer on the sidewall of the caster wheel tires.
Mower Maintenance Checking for Bent Blades Note: The machine must be on a level surface for the following procedure. Servicing the Cutting Blades 1. Raise the mower deck to the highest height-of-cut position; also considered the 'transport' position. Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. 2.
3. Measure from the tip of the blade to the flat surface here. 1 1 G014973 3 2 G014973 3 Figure 48 2 1. Opposing blade edge, in position for measuring Figure 46 2. Level surface 3. Second measured distance between blade and surface (B) 1. Blade, in position for measuring 2. Level surface 3. Measured distance between blade and surface (A) WARNING A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. 4.
Leveling the Mower Deck Check to ensure the mower deck is level any time you install the mower or when you see an uneven cut on your lawn. The mower deck must be checked for bent blades prior to leveling; any bent blades must be removed and replaced. Refer to the Checking for Bent Blades procedure before continuing. The mower deck must be leveled side-to-side first then the front to rear slope can be adjusted. Requirements: • The machine must be on a level surface. • All four tire must be properly inflated.
2. Move the motion control levers outward to the park position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 6. Move to the left side of the machine. Loosen, but do not remove, the rear locking nut on the hanger bracket (). 7. Loosen the side locking nut on the hanger bracket just enough to allow the eccentric plate to be adjusted (). Use a 3/8 inch drive extension on a socket wrench to manipulate the eccentric plate.
7. To raise the front of the mower, tighten the adjustment nut. To lower the front of the mower, loosen the adjustment nut. 8. After adjustment, check the front-to-rear slope again. Continue adjusting the nut until the front blade tip is 1/16-5/16 inch (1.6-7.9 mm) lower than the rear blade tip (). 9. When the front-to-rear blade slope is correct check the side-to-side level of the mower again; refer to Leveling the Mower from Side-to-Side. 2 2 3 Removing the Mower 1 1.
6. Attach the front support rod to the mower deck with the clevis pin and hairpin cotter (). WARNING The spring is under tension when installed and can cause personal injury. 7. Install the mower belt onto the engine pulley; refer to Replacing the Mower Belt. Be careful when removing the belt.
