Safety back toward the operator. Stop the blade(s) when crossing gravel surfaces. This machine meets or exceeds the B71.1-2003 specifications of the American National Standards Institute, in effect at the time of production. However, improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER-"personal safety instruction.
• Choose a low ground speed so you will not have to stop while operating on a slope. • Do not mow slopes when grass is wet. Slippery conditions reduce traction and could cause sliding and loss of control. • Always keep the drive wheels engaged when going down slopes. • Reduce speed and use extreme caution on slopes. • Do not make sudden turns or rapid speed changes. • Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.

Motion Control Levers and Park Position Controls Become familiar with all of the controls in Figure 4 and Figure 5 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 (Figure 16).
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 20). 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. • The motion control levers are in the park position. Overfilling may result in fuel leakage or damage to the engine or emission system. 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. 1. Clean around the fuel tank cap and remove the cap. Note: You can use the fuel window to verify the presence of gasoline before filling the tank (Figure 9). Before Starting 2.
Checking the Engine Oil Level Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Oil Level in the Engine Maintenance section. Starting the Engine 1. Sit down on the seat and move the motion controls outward to the park position. 2. Disengage the blades by moving the blade control switch to Off (Figure 11) Figure 12 1.

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 Before each use or daily Maintenance Procedure • • • • • • • Check the safety interlock system.
