    Warning

    Operating the machine to recycle lawn clippings without the plug in place allows objects to be thrown toward you or bystanders. Also, contact with the blades could occur. Thrown objects or blade contact can cause serious injury or death.

    Ensure that the rear-discharge plug is in place before you recycle the clippings. Never engage the blades without either the rear-discharge plug or the grass bag installed on the machine.

    Bagging the Clippings

    Use the grass bag when you want to collect grass and leaf clippings from the lawn.

    Warning

    A worn grass bag could allow small stones and other similar debris to be thrown toward you or bystanders, resulting in serious personal injury or death.

    Check the grass bag frequently. If it is damaged, install a new Toro replacement bag.

    Warning

    The blades are sharp; contacting the blades can result in serious personal injury.

    Operating Tips

    General Tips

    • Review the safety instructions and read this manual carefully before operating the machine.

    • Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw.

    • Keep everyone, especially children and pets, away from the area of operation.

    • Avoid striking trees, walls, curbs, or other solid objects. Never deliberately mow over any object.

    • If the machine strikes an object or starts to vibrate, immediately shut off the engine, disconnect the wire from the spark plug, and examine the machine for damage.

    • Maintain a sharp blade throughout the cutting season. Periodically file down nicks on the blade.

    • Replace the blade when necessary with an original Toro replacement blade.

    • Mow only dry grass or leaves. Wet grass and leaves tend to clump on the yard and can cause the machine to plug or the engine to stall.

      Warning

      Wet grass or leaves can cause serious injury if you slip and contact the blade.

      Mow only in dry conditions.

    • Clean under the machine after each mowing; refer to Cleaning under the Machine.

    • Keep the engine in good running condition.

    • Clean the air filter frequently. Mulching stirs up more clippings and dust which clogs the air filter and reduces engine performance.

    • Set the engine speed to the fastest position for the best cutting results.

      Warning

      Operating a machine with its engine running at a speed greater than the factory setting can cause the machine to throw a part of the blade or engine toward you or bystanders, resulting in serious personal injury or death.

      • Do not change the engine speed setting.

      • If you suspect the engine speed is faster than normal, contact an Authorized Service Dealer.

    Cutting Grass

    • Grass grows at different rates at different times of the year. In the summer heat, it is best to cut grass at the 64 mm (2-1/2 inch), 76 mm (3 inch), or 89 mm (3-1/2 inch) cutting-height settings. Cut only about a third of the grass blade at a time. Do not cut below the 64 mm (2-1/2 inch) setting unless the grass is sparse or it is late fall when grass growth begins to slow down.

    • When cutting grass over 15 cm (6 inches) tall, first mow at the highest cutting-height setting and walk slower; then mow again at a lower setting for the best lawn appearance. If the grass is too long and the leaves clump on top of the lawn, the machine may plug and cause the engine to stall.

    • Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization.

    If the finished lawn appearance is unsatisfactory, try 1 or more of the following:

    • Sharpen the blade.

    • Walk at a slower pace while mowing.

    • Raise the cutting height on your machine.

    • Cut the grass more frequently.

    • Overlap cutting swaths instead of cutting a full swath with each pass.

    Cutting Leaves

    • After cutting the lawn, ensure that half of the lawn shows through the cut leaf cover. You may need to make more than a single pass over the leaves.

    • For light leaf coverage, set all the wheels at the same cutting-height setting.

    • Slow down your mowing speed if the machine does not cut the leaves finely enough.

    After Operation

    After Operation Safety

    General Safety

    • Always shut off the machine, wait for all moving parts to stop, and allow the machine to cool before adjusting, servicing, cleaning, or storing it.

    Servicing the Spark Plug

    Maintenance Service IntervalMaintenance Procedure
    Every 100 hours
  • Inspect, clean, and adjust the spark plug gap; replace the spark plug if necessary.
    		•

    Use an NGK BPR5ES spark plug or equivalent.

    1. Shut off the engine and wait for all moving parts to stop.

    2. Disconnect the wire from the spark plug.

    3. Clean around the spark plug.

    4. Remove the spark plug from the cylinder head.

      Important: Replace a cracked, fouled, or dirty spark plug. Do not clean the electrodes because grit entering the cylinder can damage the engine.

    5. Set the gap on the plug to 0.76 mm (0.030 inch); refer to Figure 27.

      Figure 27

      1. Center-electrode insulator
      2. Side electrode
      3. Air gap (not to scale)

    6. Carefully install the spark plug by hand (to avoid cross threading) until it is hand tight.

    7. Tighten the spark plug to 23 N∙m (2.3 kgf-m, 17 ft-lb).

      Important: A loose spark plug can become very hot and can damage the engine; overtightening a spark plug may damage the threads in the cylinder head.

    8. Connect the wire to the spark plug.

    Adjusting the Self-Propel Drive

    If the machine is new, does not self-propel, or it tends to creep forward, adjust the drive cable.

    1. Move the machine outside and onto a paved surface near a solid wall to safely prevent the machine from moving forward while the engine is running.

    2. Position the machine with the front tires against the wall.

      Note: Ensure that the area is well ventilated and clear of debris that could be thrown by the machine.

    3. Shift the transmission to third gear.

    4. Start the engine; refer to Starting the Engine.

    5. Pull the self-propel-drive bar to the handle.

      Note: The wheels should start to turn as the self-propel-drive bar just touches the handle.

    6. Shut off the engine.

    7. If you must adjust the machine, do the following:

      • If the wheels do not spin when you engage the self-propel-drive bar, the traction belt is too loose. Rotate the wheel-drive-control knob (Figure 28) clockwise 1 turn and repeat steps 4 through 6.

        g024465

        Figure 28

        1. Wheel-drive-control knob

      • If the wheels spin before you fully engage the self-propel-drive bar, the traction belt is too tight. Rotate the wheel-drive-control knob (Figure 28) counterclockwise 1 turn and repeat steps 4 through 6.

    8. For a new traction belt, rotate the drive-cable-adjustment knob clockwise 1 additional turn to allow for the normal stretching of the belt during the break-in period.

      Note: You can skip this step if you are adjusting a used belt.

    Maintaining the Blade

    Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades.

    1. Shut off the engine and wait for all moving parts to stop.

    2. Disconnect the wire from the spark plug.

    3. Close the fuel valve by moving the fuel-valve lever to the left.

    4. Drain the fuel from the fuel tank.

    5. Tip the machine onto its right side (air cleaner up) as shown in Figure 29.

    Inspecting the Blade

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Inspect the mower blades for wear or damage.
    		•

    Carefully examine the blade for sharpness and wear, especially where the flat and the curved parts meet (Figure 30A). Because sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the machine. If you notice a slot or wear (Figure 30B and Figure 30C), replace the blade; refer to Removing the Blade.

    g002278

    2. Flat part of the blade
    3. Wear
    4. Slot formed

    Note: For the best performance, install a new blade before the mowing season begins. During the year, file down any small nicks to maintain the cutting edge.

    Danger

    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.

    • Inspect the blade periodically for wear or damage.

    • Replace a worn or damaged blade.

    Inspecting the Accelerator

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Inspect the accelerator for wear or damage.
    		•

    Carefully examine the accelerator for excessive wear (Figure 31). Because sand and abrasive material can wear away the metal (especially in the area shown as item 2 in Figure 31), check the accelerator before using the machine. If you notice that a tab on the accelerator has been worn down to a sharp edge or there is a crack, replace the accelerator.

    g027496

    4. Crack formed

    Warning

    A worn or damaged accelerator can break, and a piece of the accelerator could be thrown at you or bystanders, resulting in serious personal injury or death.

    • Inspect the accelerator periodically for wear or damage.

    • Replace a worn or damaged accelerator.

    Removing the Blade

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

    2. Remove the blade bolt, the lock washer, the accelerator, and the blade (Figure 30).

    Sharpening the Blade

    Maintenance Service IntervalMaintenance Procedure
    Every 50 hours
  • Sharpen or replace the blade.Maintain it more frequently if the edge dulls quickly in rough or in sandy conditions.
    		•

    File the top side of the blade to maintain its original cutting angle (Figure 32A) and inner cutting edge radius (Figure 32B). The blade will remain balanced if you remove the same amount of material from both cutting edges.

    g002279

    Figure 32

    1. Sharpen the blade at this angle only.
    2. Maintain the original radius here.

    Balancing the Blade

    1. Check the balance of the blade by placing the center hole of the blade over a nail or screwdriver shank clamped horizontally in a vise (Figure 33).

      g002280

      Figure 33

      Note: You can also check the balance using a commercially manufactured blade balancer.

    2. If either end of the blade rotates downward, file that end (not the cutting edge or the end near the cutting edge) until neither end of the blade drops.

    Installing the Blade

    1. Install a sharp, balanced Toro blade, the accelerator, the lock washer, and the blade bolt. The sail of the blade must point toward the top of the mower housing for proper installation.

      Note: Torque the blade bolt to 82 N∙m (60 ft-lb).

      Warning

      Operating the machine without the accelerator in place can cause the blade to flex, bend, or break, resulting in serious injury or death to you or to bystanders.

      Do not operate the machine without the accelerator in place.

    2. Return the machine to the operating position.

    Cleaning under the Belt Cover

    Maintenance Service IntervalMaintenance Procedure
