Before Operation

Before Operation Safety

General Safety

  • Never allow children or untrained people to operate or service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.

  • Become familiar with the safe operation of the equipment, operator controls, and safety signs.

  • Know how to stop the machine and shut off the engine quickly.

  • Check that operator-presence controls, safety switches, and shields are attached and functioning properly. Do not operate the machine unless they are functioning properly.

  • Before mowing, always inspect the machine to ensure that the blades, blade bolts, and cutting assemblies are in good working condition. Replace worn or damaged blades and bolts in sets to preserve balance.

  • Inspect the area where you will use the machine and remove all objects that the machine could throw.

  • Evaluate the terrain to determine the appropriate equipment and any attachments or accessories required to operate the machine properly and safely.

Fuel Safety

  • To avoid personal injury or property damage, use extreme care in handling fuel. Fuel vapors are flammable and explosive.

  • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

  • Use only an approved fuel container.

  • Do not remove the fuel cap or add fuel to the fuel tank while the engine is running or while hot.

  • Do not refuel the machine indoors.

  • Do not store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or on other appliances.

  • Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle before filling.

  • Remove the equipment from the truck or trailer and refuel it while it is on the ground. If this is not possible, then refuel from a portable container rather than a fuel-dispenser nozzle.

  • Do not operate the machine without the entire exhaust system in place and in proper working condition.

  • 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.

  • If you spill fuel on your clothing, change your clothing immediately. Wipe up any fuel that spills.

  • Never overfill the fuel tank. Replace the fuel cap and tighten it securely.

  • Store fuel in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of fuel.

  • Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows fuel to expand.

    • Avoid prolonged breathing of vapors.

    • Keep your face away from the nozzle and fuel tank opening.

    • Avoid contact with skin; wash off spills with soap and water.

Recommended Fuel

  • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

  • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.

  • Do not use gasoline containing methanol.

  • Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.

  • Do not add oil to gasoline.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

  • Keeps fuel fresh during storage of 90 days or less (drain the fuel tank when storing the machine for more than 90 days)

  • Cleans the engine while it runs

  • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting

    Important: Do not use fuel additives containing methanol or ethanol.

    Add the correct amount of fuel stabilizer/conditioner to the fuel.

    Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Filling the Fuel Tank

  1. Park the machine on a level surface.

  2. Engage the parking brake.

  3. Shut off the engine and remove the key.

  4. Clean around the fuel-tank cap.

  5. Fill the fuel tank to the bottom of the filler neck (Figure 9).

    Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel to expand.

    g027243

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.

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.

    During Operation

    During Operation Safety

    General Safety

    • The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.

    • Wear appropriate clothing, including eye protection; slip-resistant, substantial footwear; and hearing protection. Tie back long hair and do not wear jewelry.

    • Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.

    • Never carry passengers on the machine and keep bystanders and pets away from the machine during operation.

    • Operate the machine only in good visibility to avoid holes or hidden hazards.

    • Avoid mowing on wet grass. Reduced traction could cause the machine to slide.

    • Ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position before you start the engine.

    • Keep your hands and feet away from the cutting units. Keep clear of the discharge opening at all times.

    • Look behind and down before backing up to be sure of a clear path.

    • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

    • Do not mow near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge gives way.

    • Stop the blades whenever you are not mowing.

    • Stop the machine and inspect the blades after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.

    • Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

    • Disengage the drive to the cutting unit and shut off the engine before adjusting the height of cut (unless you can adjust it from the operating position).

    • Never run an engine in an area where exhaust gases are enclosed.

    • Never leave a running machine unattended.

    • Before leaving the operating position (including to empty the catchers or to unclog the chute), do the following:

      • Park the machine on a level surface.

      • Disengage the power take-off and lower the attachments.

      • Engage the parking brake.

      • Shut off the engine and remove the key.

    • 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

    • Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.

    • Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope requires extra caution.

    • Operate the machine at a lower speed when you are on a slope.

    • If you feel uneasy operating the machine on a slope, do not do it.

    • Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

    • Choose a low ground speed so you will not have to stop or shift while on a slope.

    • A rollover can occur before the tires lose traction.

    • Avoid operating the machine on wet grass. Tires may lose traction; regardless if the brakes are available and functioning.

    • Avoid starting, stopping, or turning the machine on a slope.

    • Keep all movement on slopes slow and gradual. Do not suddenly change the speed or direction of the machine.

    • Do not operate the machine near drop-offs, ditches, embankments, or bodies of water. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard (2 machine widths).

    2. Move the throttle lever to the FAST position.

    3. Turn the ignition key to the OFF position and remove the key.

    Using the Motion-Control Levers

    g004532

    Driving the Machine

    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.

    The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance. Always operate in the full throttle position when mowing.

    Warning

    The machine can spin very rapidly. You may lose control of the machine and cause personal injury or damage to the machine.

    • Use caution when making turns.

    • Slow the machine down before making sharp turns.

    Warning

    Children or bystanders may be injured if they move or attempt to operate the mower while it is unattended.

    Always remove the ignition key and move the motion-control levers outward to the PARK position when leaving the machine unattended, even if just for a few minutes.

    Adjusting the Height of Cut

    Note: The transport position is the highest height-of-cut position at 115 mm (4-1/2 inches) as shown in Figure 25.

    g028025

    Adjusting the Anti-Scalp Rollers

    Whenever you change the height of cut, adjust the height of the anti-scalp rollers.

    Note: Adjust the anti-scalp rollers so that the rollers do not touch the ground in normal, flat mowing areas.

    1. Disengage the blade-control switch (PTO), move the motion-control levers to the PARK position, and engage the parking brake.

    2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

    3. Adjust the anti-scalp rollers as shown in Figure 26 to match the closest height-of-cut position.

      g010233

    Using the Side Discharge

    The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.

    Danger

    Without a grass deflector, discharge cover, or a 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.

    • Never put your hands or feet under the mower.

    • Never try to clear the discharge area or mower blades unless you move the blade-control switch (PTO) to the OFF position, rotate the ignition key to the OFF position, and remove the key.

    • Make sure that the grass deflector is in the down position.

    Operating Tips

    Using the 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 in uncut grass. Always try to have 1 side of the mower free from uncut grass, which allows air to be drawn into the mower.

    Cutting a Lawn for the First Time

    Cut grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than 15 cm (6 inches) tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.

    Cutting a Third of the Grass Blade

    It is best to cut only about a third 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.

    Alternating the Mowing Direction

    Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization.

    Mowing at Correct Intervals

    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.

    Using a Slower Cutting Speed

    To improve cut quality, use a slower ground speed in certain conditions.

    Avoiding Cutting Too Low

    When mowing uneven turf, raise the cutting height to avoid scalping the turf.

    Stopping the Machine

    If you must stop the forward motion of the machine while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or you can disengage the mower deck while moving forward.

    Keeping the Underside of the Mower Clean

    Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.

    Maintaining the Blade(s)

    Maintain a sharp blade throughout the cutting season because a sharp blade cuts 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. Check the mower blades after each use 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.

    After Operation

    After Operation Safety

    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.
