Smart Speed™ Control System Lever Operation The Smart Speed™ Control-System lever, located below the operating position, gives you a choice to drive the machine at 3 speed ranges— trim, tow, and mow (Figure 5). Before Operation Fuel-Presence Window Before Operation Safety You can use the fuel window, located on the left side of the machine, to verify the presence of fuel in the tank (Figure 7). General Safety • Never allow children or untrained people to operate or service the machine.
Using Stabilizer/Conditioner • Keep the fuel-dispenser nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device. Use a fuel stabilizer/conditioner in the machine to provide the following benefits: • If you spill fuel on your clothing, change your clothing • Keeps fuel fresh during storage of 90 days or less (drain immediately. Wipe up any fuel that spills.
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 Engine-Oil Level (page 13). Breaking in a New Machine New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance.
Positioning the Seat Using the Safety-Interlock System A B WARNING If the safety-interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine.
Adjusting the Motion-Control Levers During Operation During Operation Safety Adjusting the Height General Safety You can adjust the motion-control levers higher or lower for maximum comfort (Figure 12). A • The owner/operator can prevent and is responsible for B • • • • • g027252 g027252 Figure 12 • Adjusting the Tilt • You can adjust the motion-control levers forward or rearward for your comfort. • 1. Loosen the upper bolt holding the control lever to the control-arm shaft. • 2.
Disengaging the Blade-Control Switch (PTO) – Wait for all moving parts to stop. • Do not operate the machine when there is the risk of lightning. 1 • Do not use the machine as a towing vehicle. • Do not change the governor speed or overspeed the engine. • Use accessories and attachments approved by Toro only. Slope Safety • Slow down the machine and use extra care on hillsides. Travel up and down on hillsides. Turf conditions can affect the stability of the machine.
Operating the Ignition Switch Starting and Shutting Off the Engine 1. Turn the ignition key to the START position (Figure 16). Note: When the engine starts, release the key. Starting the Engine Important: Do not engage the starter for more than 5 seconds at a time. If the engine fails to start, wait 15 seconds between attempts. Failure to follow these instructions can burn out the starter motor. Important: Do not engage the starter for more than 5 seconds at a time.
Driving the Machine Shutting Off the Engine 1. Disengage the blades by moving the blade-control switch to the OFF position (Figure 14). The drive wheels turn independently, powered by hydraulic motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require sometime for you to adapt to how it moves. 2. Move the throttle lever to the FAST position. 3.
Driving Backward 3. Adjust the lever to the desired position. 1. Move the levers to the center, unlocked position. The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass. 2. To go backward, slowly pull the motion-control levers rearward (Figure 20). Suggested uses: Trim Parking X Heavy, wet grass X Training X Tow Bagging X Mulching X Mow Normal mowing X Transport X Trim This is the lowest speed.
Stopping the Machine Adjusting the Anti-Scalp Rollers To stop the machine, move the motion-control levers to NEUTRAL and outward to the PARK position, disengage the blade-control switch, ensure that the throttle is in the FAST position, and turn the ignition key to OFF. Remove the key from the ignition switch. For Machines with 107 cm (42-inch) Mower Decks Whenever you change the height of cut, adjust the height of the anti-scalp rollers.
Using the Side Discharge Mowing at Correct Intervals The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Grass grows at different rates at different times of the year. To maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height, then mow again 2 days later at a lower height setting.
After Operation Note: Do not start the machine. Note: You can now push the machine by hand. After Operation Safety 3 General Safety • Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills. • Shut off the fuel before storing or transporting the machine. • Disengage the drive to the attachment whenever you are transporting or not using the machine. • Use full-width ramps for loading the machine into a trailer or truck.
Transporting the Machine Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.
Loading the Machine 1 Use extreme caution when loading or unloading machines onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Back up the ramp and drive forward down the ramp (Figure 26). g027995 Figure 26 1. Back the machine up the ramp. 2 2. Drive the machine forward down the ramp. Important: Do not use narrow individual ramps for each side of the machine.

Always replace the spark plug(s) when it has: a black coating, worn electrodes, an oily film, or cracks. Note: If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty. Set the gap to 0.76 mm (0.030 inch).
Fuel System Maintenance DANGER In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you, others, and can damage property. • Perform any fuel-related maintenance when the engine is cold. Do this outdoors in an open area. Wipe up any fuel that spills. • Never smoke when draining fuel, and stay away from an open flame or where a spark may ignite the fuel fumes.
Electrical System Maintenance Electrical System Safety g027590 g027590 • Disconnect the battery before repairing the machine. Disconnect the negative terminal first and the positive last. Connect the positive terminal first and the negative last. • Charge the battery in an open, well-ventilated area, away from sparks and flames. Unplug the charger before connecting or disconnecting the battery. Wear protective clothing and use insulated tools.
3. When the battery is fully charged, unplug the charger from the electrical outlet, then disconnect the charger leads from the battery posts (Figure 42). WARNING Incorrect battery-cable routing could damage the machine and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable.
Servicing the Fuses Drive System Maintenance The electrical system is protected by fuses. It requires no maintenance; however, if a fuse blows, check the component/circuit for a malfunction or short. Fuse type: Checking the Tire Pressure • Main—F1 (30 A, blade-type) Service Interval: Every 25 hours—Check tire pressure. • Charge Circuit—F2 (25 A, blade-type) Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut.
Releasing the Electric Brake Mower Maintenance You can manually release the electric brake by rotating the link arms forward. Once the electric brake is energized, the brake resets. Servicing the Cutting Blades 1. Turn the ignition key to the OFF position or disconnect the battery. To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, keep extra blades on hand. 2.
Checking for Bent Blades Note: The machine must be on a level surface for the following procedure. 3 1. Raise the mower deck to the highest height-of-cut position. 2. While wearing thickly padded gloves, or other adequate hand protection, slowly rotate the blade to be measure into a position that allows effective measurement of the distance between the cutting edge and the level surface the machine is on (Figure 47). 2 1 G009681 g009681 Figure 49 1. Blade (side previously measured) 2.
Removing the Blades Note: The blade retains its balance if the same amount of material is removed from both cutting edges. The blades must be replaced if a solid object is hit, if the blade is out of balance, or if the blade is bent. For best performance and continued safety conformance of the machine, use genuine Toro replacement blades. Replacement blades made by other manufacturers may result in non-conformance with safety standards. g000552 Figure 53 1.
