Safety • Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove key before dismounting. 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.
• Be aware that loss of traction may occur going downhill. • • • • • • On slopes, the weight of the towed equipment may cause Weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking and steering. Always avoid sudden starting or stopping on a slope. If tires lose traction, stop the machine, disengage the blades and proceed slowly off the slope. Use extreme care with grass catchers or other attachments.
and replace with manufacturers' recommended parts, when necessary. • Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them. • Check for proper brake operation frequently. Adjust and service as required. • Maintain or replace safety and instruction decals as necessary. • Use only genuine Toro replacement parts to ensure that original standards are maintained.

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 22). 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.
2. Slowly add regular, unleaded gasoline until the fuel reaches the base of the filler neck (Figure 11). 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 2 Before Starting 3 Recommended Fuel 4 • 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.
Starting the Engine 1. Sit down on the seat and move the motion controls outward to the park position. 2.

Positioning the Seat Adjusting the Motion Control Levers The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable. Adjusting the Height The motion control levers can be adjusted higher or lower for maximum operator comfort. Models 74625, 74626, and 74631 1. Raise the seat and loosen the adjustment bolts just enough that seat can move (Figure 25). 1. Remove the 2 bolts holding the control lever to the control arm shaft (Figure 27).
3. Locate the bypass levers on the frame on both sides of the engine. 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. • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.
Mowing Direction Alternate mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization. Mow at Correct Intervals Normally, mow every four days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently.
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 After each use • Clean the mower deck housing.

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 (Figure 45). 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 Servicing the Cutting Blades 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. Figure 47 Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary.
3. Measure from the tip of the blade to the flat surface here. 1 1 G014973 3 2 G014973 3 Figure 51 2 1. Opposing blade edge, in position for measuring Figure 49 2. Level surface 3.
