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.

Adding Fuel

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 until the fuel gauge reads at the full mark (Figure 8).

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

    g197123

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 NEUTRAL-LOCK position.

  • The parking brake is engaged.

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

    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; long pants; 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:

      • Stop the machine on level ground.

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

      • Engage the parking brake.

      • Shut off the engine and remove the key.

      • Wait for all moving parts to stop.

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

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

    • 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

    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 degrees.

      • 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.

    • A 2-post ROPS (Rollover Protection System) is available for the machine as an accessory. A ROPS is recommended if you will be mowing next to drop-offs, near water, or on steep banks, which could result in a rollover. Contact an Authorized Service Dealer for more details.

    g229111

    Towing Safety

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

    • Follow the attachment manufacturer's recommendation for weight limits for towed equipment and towing on slopes. The towed weight must not exceed the weight of the machine, operator, and ballast. Use counterweights or wheel weights as described in the attachment, or in the towing machine Operator’s Manual.

    • 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 increases 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 Parking Brake

    Always engage the parking brake when you stop the machine or leave it unattended.

    Using the Motion-Control Levers

    c:\data\documentum\checkout\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.

    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 or lock the deck in the highest height of cut or transport position. You can use the height-of-cut lever with the foot pedal to lock the deck in a specific cutting height.

    Using the Foot Pedal Deck-Lift System

    • Press the deck-lift pedal down to raise the deck; continue to press the pedal until the deck locks in the transport position (Figure 25).

    • Push on the deck-lift pedal with your foot and pull the transport lock handle rearward to disengage the transport lock (Figure 25).

    g024409

    Adjusting the Height of Cut

    You can adjust the height of cut from 38 to 114 mm (1-1/2 to 4-1/2 inches) in 6 mm (1/4 inch) increments by moving the height-of-cut pin into different hole locations.

    1. Push on the deck-lift pedal with your foot and raise the mower deck to the transport-lock position (also the 114 mm (4-1/2 inch) cutting height position) as shown in Figure 26.

    2. To adjust, remove the pin from the height-of-cut bracket (Figure 26).

    3. Select a hole in the height-of-cut system corresponding to the desired height of cut and insert the pin (Figure 26).

    4. Push on the deck-lift pedal with your foot and pull the handle rearward to disengage the transport lock (Figure 25).

    5. Lower the deck slowly until the lever makes contact with the pin.

      g188850

    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. Park the machine on a level surface, disengage the blade-control switch and engage the parking brake; refer to Engaging 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 27.

      g029955

    Converting to Side Discharge

    The mower deck and mower blades shipped with the machine were designed for optimum mulching and side-discharge performance.

    Install the fasteners into the same holes in the deck from where they were originally removed. This ensures that no holes are left open when operating the mower deck.

    Warning

    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 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.

    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 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.

    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.

    Do not drive the machine on a public street or roadway.

    Selecting a Trailer

    Warning

    Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death (Figure 37).

    • Use only a full-width ramp; do not use individual ramps for each side of the machine.

    • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.

    • Ensure that the length of the ramp is at least 4 times as long as the height of the trailer or truck bed to the ground. This ensures that the ramp angle does not exceed 15 degrees on flat ground.

    g027996

    Loading the Machine

    Warning

    Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death.

    Mower Maintenance

    Servicing the Cutting Blades

    To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, keep extra blades on hand.

    Blade Safety

    A worn or damaged blade can break, and a piece of the blade could be thrown toward you or bystanders, resulting in serious personal injury or death. Trying to repair a damaged blade may result in discontinued safety certification of the product.

    • Inspect the blades periodically for wear or damage.

    • Use care when checking the blades. Wrap the blades or wear gloves, and use caution when servicing the blades. Only replace or sharpen the blades; never straighten or weld them.

    • On multi-bladed machines, take care as rotating 1 blade can cause other blades to rotate.

    Before Inspecting or Servicing the Blades

    1. Park the machine on a level surface, disengage the blade-control switch (PTO), and engage the parking brake.

    2. Shut off the engine, remove the key, and disconnect the spark-plug wires from the spark plugs.

    Inspecting the Blades

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Inspect the blades.
    1. Inspect the cutting edges (Figure 60).

    2. If the edges are not sharp or have nicks, remove and sharpen the blade; refer to Sharpening the Blades.

    3. Inspect the blades, especially in the curved area.

    4. If you notice any cracks, wear, or a slot forming in this area, immediately install a new blade (Figure 60).

      g006530

    Checking for Bent Blades

    Note: The machine must be on a level surface for the following procedure.

    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 into a position that allows you to measure the distance between the cutting edge and the level surface the machine is on (Figure 61).

      g014972
    3. Measure from the tip of the blade to the flat surface (Figure 62).

      g014973
    4. Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position (Figure 63).

      g014974
    5. Measure from the tip of the blade to the flat surface (Figure 64).

      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 65).

      g010341

    Sharpening the Blades

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 66).

      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 67).

      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 66).

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

    Installing the Blades

    1. Install the blade onto the spindle shaft (Figure 65).

      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 65).

    3. Torque the blade bolt to 135 to 150 N∙m (100 to 110 ft-lb).
