  • Do not operate the machine unless all guards and safety devices, such as the deflectors and the entire grass catcher, are in place and functioning properly. Replace worn or deteriorated parts when necessary.

Fuel Safety

  • Fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.

    • To prevent a static charge from igniting the fuel, remove the machine from the truck or trailer and refuel it on the ground, away from all vehicles. If this is not possible, place a portable fuel container on the ground, away from all vehicles, and fill it; then refuel the machine from the fuel container rather than from a fuel-dispenser nozzle.

    • Fill the fuel tank outdoors on level ground, in an open area, and when the engine is cold. Wipe up any fuel that spills.

    • Do not handle fuel when smoking or around an open flame or sparks.

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

    • If you spill fuel, do not attempt to start the engine. Avoid creating a source of ignition until the fuel vapors have dissipated.

    • Store fuel in an approved container and keep it out of the reach of children.

  • Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

    • Avoid prolonged breathing of vapors.

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

    • Keep fuel away from your eyes and skin.

  • 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 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.

  • Do not overfill the fuel tank. Replace the fuel cap and tighten it securely.

  • Clean grass and debris from the cutting unit, muffler, drives, grass catcher, and engine compartment to help prevent fires. Clean up oil or fuel spills.

Performing Daily Maintenance

Before starting the machine each day, perform the Each Use/Daily procedures listed in .

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.

Using the Safety-Interlock System

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.

Understanding the Safety-Interlock System

The safety-interlock system is designed to prevent the engine from starting unless:

  • The blade-control switch (PTO) is disengaged.

  • The motion-control levers are in the PARK position.

The safety-interlock system also is designed to shut off the engine whenever the control levers are out of the PARK position and you rise from the seat.

    During Operation Safety

    General Safety

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

    • Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

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

    • Contacting the blade can result in serious personal injury. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. When you turn the key to the OFF position, the engine should shut off and the blade should stop. If not, stop using your machine immediately and contact an Authorized Service Dealer.

    • Operate the machine only in good visibility and appropriate weather conditions. Do not operate the machine when there is the risk of lightning.

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

    • Do not mow with the discharge deflector raised, removed, or altered unless there is a grass-collection system or mulch kit in place and working properly.

    • Do not mow in reverse unless it is absolutely necessary. Always look down and behind you before moving the machine in reverse.

    • Use extreme care when approaching blind corners, shrubs, trees, or other objects that may block your view.

    • Stop the blades whenever you are not mowing.

    • If the machine strikes an object or starts to vibrate, immediately shut off the engine, remove the key (if equipped), and wait for all moving parts to stop before examining the machine for damage. 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.

    • Before you leave the operating position, do the following:

      • Park the machine on a level surface.

      • Disengage the power takeoff and lower the attachments.

      • Engage the parking brake.

      • Shut off the engine and remove the key.

      • Wait for all moving parts to stop.

    • Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is lethal if inhaled.

    • Never leave a running machine unattended.

    • Attach towed equipment to the machine only at the hitch point.

    • Do not operate the machine unless all guards and safety devices, such as the deflectors and the entire grass catcher, are in place and functioning properly. Replace worn or deteriorated parts when necessary.

    • Use only accessories and attachments approved by Toro.

    • This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.

      g229846
    • Clean grass and debris from the cutting unit, drives, muffler, and engine to help prevent fires.

    • Start the engine with your feet well away from the blades.

    • Be aware of the mower discharge path and direct the discharge away from others. Avoid discharging material against a wall or obstruction because the material may ricochet back toward you.

    • Stop the blades, slow down the machine, and use caution when crossing surfaces other than grass or when transporting the machine to and from the operating area.

    • Do not change the engine governor speed or overspeed the engine.

    • Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

    • Keep children out of the operating area and under the watchful care of a responsible adult other than the operator.

    • Be alert and shut off the machine if children enter the operating area.

    • Before backing up or turning the machine, look down and all around for small children.

    • Do not carry children on the machine, even when the blades are not moving. Children could fall off and be seriously injured or prevent you from safely operating the machine. Children who have been given rides in the past could appear in the operating area without warning and be run over or backed over by the machine.

    Slope Safety

    • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. The operator is responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, do the following:

      • Review and understand the slope instructions in the manual and on the machine.

      • Use an angle indicator to determine the approximate slope angle of the area.

      • Never operate on slopes greater than 15°.

      • Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.

    • Identify hazards at the base of the slope. Do not operate the machine near drop-offs, ditches, embankments, water, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard. Use a walk-behind machine or a hand trimmer to mow the grass in these areas.

    • Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.

    • Do not operate a machine under any conditions where traction, steering, or stability is in question. Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. The machine can slide even if the drive wheels are stopped.

    • Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.

    • Use extra care while operating with accessories or attachments, such as grass-collection systems. These can change the stability of the machine and cause a loss of control. Follow directions for counterweights.

    • If possible, keep the deck lowered to the ground while operating on slopes. Raising the deck while operating on slopes can cause the machine to become unstable.

    g229111

    Towing Safety

    • Do not attach towed equipment except at the hitch point.

    • Do not use the machine as a towing vehicle unless it has a hitch installed.

    • Do not exceed the weight limits for towed equipment and towing on slopes. The towed weight must not exceed the weight of the machine and operator.

    • Never allow children or others near the towed equipment.

    • On slopes, the weight of the towed equipment may cause loss of traction, increased risk of rollover, and loss of control. Reduce the towed weight and slow down.

    • The stopping distance may increase with the weight of a towed load. Travel slowly and allow extra distance to stop.

    • Make wide turns to keep the attachment clear of the machine.

    Operating the Mower Blade-Control Switch (PTO)

    The blade-control switch (PTO) starts and stops the mower blades and any powered attachments.

    Engaging the Blade-Control Switch (PTO)

    g008945

    Note: Always engage the blades with the throttle in the FAST position (Figure 15).

    g295538

    Disengaging the Blade-Control Switch (PTO)

    g009174

    Operating the Throttle

    You can move the throttle control between the FAST and SLOW positions (Figure 17).

    g187517

    Operating the Choke

    Use the choke to start a cold engine.

    1. Pull up the choke knob to engage the choke before using the key switch (Figure 18).

      Note: Ensure that you fully engage the choke. You may need to hold the knob up when you use the key switch.

    2. Push down the choke to disengage the choke after the engine has started (Figure 18).

      g008959

    Starting the Engine

    Note: A warm or hot engine may not require choking.

    Important: Do not engage the starter for more than 5 seconds at a time. Engaging the starter motor for more than 5 seconds can damage the starter motor. If the engine fails to start, wait 10 seconds before operating the engine starter again.

    g295541

    Shutting Off the Engine

    1. Disengage the blades by moving the blade-control switch to the OFF position.

    2. Move the motion-control levers outward to the PARK position.

    3. Move the throttle control to between the half and full throttle position.

    4. Turn the key to the OFF position and remove the key.

    Caution

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

    Always remove the key and engage the parking brake when leaving the machine unattended.

    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 some time 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.

    Driving Forward

    Note: Always use caution when turning.

    1. Move the levers to the center, unlocked position.

    2. To go forward, slowly push the motion-control levers forward (Figure 21).

      g008952

    Driving Backward

    Note: Always use caution when backing up and turning.

    1. Move the levers to the center, unlocked position.

    2. To go backward, slowly pull the motion-control levers rearward (Figure 22).

      g008953

    Using the Smart Speed

    The Smart Speed TM Control-System lever, located below the operating position (Figure 22), gives the operator a choice to drive the machine at 3 ground speed ranges—trim, tow, and mow.

    g298907

    To change speeds, do the following:

    1. Move the motion-control levers to neutral and outward to the PARK position.

    2. Disengage the blade-control switch.

    3. Adjust the lever to the desired position.

    The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass.

    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 deck 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 deck.

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

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

    Adjusting the Height of Cut

    The machine is equipped with a foot pedal deck-lift system. You can use the foot pedal to lift the deck briefly to avoid obstacles and to raise the deck.

    You can adjust the height of cut from 38 to 114 mm (1-1/2 to 4-1/2 inches) in 13 mm (1/2 inch) increments by moving the height-of-cut pin into different hole locations.

    1. Push on the deck-lift pedal with your foot to raise the mower deck.

    2. To adjust, remove the pin from the height-of-cut bracket (Figure 24).

    Operating Tips

    Maximizing Air Circulation

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

    Cutting a Lawn for the First Time

    Cut grass slightly longer than normal to ensure that the cutting height of the mower deck 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.

    Mowing at Slower Speeds

    In certain conditions, mowing at a slower ground speed can improve cut quality.

    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 Deck Clean

    Clean clippings and dirt from the underside of the mower deck after each use. If grass and dirt build up inside the mower deck, 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. Refer to Servicing the Cutting Blades.

    5. Measure from the tip of the blade to the flat surface (Figure 54).

      Note: The variance should be no more than 3 mm (1/8 inch).

      g014973
      1. If the difference between A and B is greater than 3 mm (1/8 inch), replace the blade with a new blade; refer to Removing the Blades and Installing the Blades.

        Note: If a bent blade is replaced with a new blade, and the dimension obtained continues to exceed 3 mm (1/8 inch), the blade spindle could be bent. Contact an Authorized Service Dealer for service.

      2. If the variance is within constraints, move to the next blade.

    6. Repeat this procedure on each blade.

    Removing the Blades

    Replace the blades if they hit a solid object, or if the blade is out of balance or bent.

    1. Hold the blade end using a rag or thickly padded glove.

    2. Remove the blade bolt, curved washer, and blade from the spindle shaft (Figure 55).

      g027833

    Sharpening the Blades

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 56).

      Note: Maintain the original angle.

      Note: The blade retains its balance if the same amount of material is removed from both cutting edges.

      g000552
    2. Check the balance of the blade by putting it on a blade balancer (Figure 57).

      Note: If the blade stays in a horizontal position, the blade is balanced and can be used.

      Note: If the blade is not balanced, file some metal off the end of the sail area only (Figure 56).

      g000553
    3. Repeat this procedure until the blade is balanced.

    Installing the Blades

    1. Install the blade onto the spindle shaft (Figure 55).

      Important: The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting.

    2. Install the curved washer (cupped side toward the blade) and the blade bolt (Figure 55).

    3. Torque the blade bolt to 81 to 108 N∙m (60 to 80 ft-lb).

    Leveling the Mower Deck
