Motion Control Levers and Park Position Controls Become familiar with all of the controls in Figure 4, Figure 5, and Figure 6 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.
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 (Figure 21). 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 blades are disengaged. Filling the Fuel Tank • The motion control levers are in the park position. Make sure the engine is shut off and the motion controls are in the park position. Tank maximum capacity is 2.9 gallons. 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. Important: Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck.

Cut 1/3 of the Grass Blade 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. It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.
shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.
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. Before each use or daily • • • • • • Check the safety interlock system. Check the engine oil level. Clean the air intake screen. Check the cutting blades. Inspect the grass deflector for damage Clean the mower housing.
