    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 blades 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 sharp blades throughout the cutting season. Periodically file down nicks on the blades.

    • Replace the blades when necessary with original Toro replacement blades.

    • 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.

    • Clean the underside of the machine deck after each mowing. Refer to Cleaning under the Machine.

    • Keep the engine in good running condition.

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

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

    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 51 mm (2 inch), 64 mm (2-1/2 inch), or 83 mm (3 inch) cutting-height settings. Cut only about a third of the grass blade at a time. Do not cut below the 51 mm (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 blades.

    • 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

    • Clean grass and debris from the machine to help prevent fires. Clean up oil or fuel spills.

    • Allow the engine to cool before storing the machine in any enclosure.

    Servicing the Blades

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the blades and service them, if necessary.
  • Important: You will need a torque wrench to install the blades properly. If you do not have a torque wrench or are uncomfortable performing this procedure, contact an Authorized Service Dealer.

    Examine the blades for sharpness and any wear or damage whenever you run out of fuel; refer to Inspecting the Blades. If the blade edge is dull or nicked, have it sharpened or replace it. If the blades are worn, bent, damaged or cracked, replace them immediately with genuine Toro replacement blades.

    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 blades periodically for wear or damage.

    • Replace worn or damaged blades.

    Note: Maintain sharp blades throughout the cutting season, because sharp blades cut 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.

    Preparing to Service the Cutting Blades

    Tip the machine onto its side, with the air filter up in the air, until the upper handle rests on the ground.

    Warning

    The blades are sharp; contacting a blade could result in serious personal injury.

    • Disconnect the wire from the spark plug.

    • Wear gloves when servicing the blades.

    Inspecting the Blades

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Inspect the blades.
    1. Inspect the cutting edges (Figure 30). If the edges are not sharp or have nicks, remove the blades and have them sharpened or replace them.

      g017223
    2. Inspect the blades themselves, especially the curved area (Figure 30). If you notice any damage, wear, or a slot forming in this area, immediately replace them with new blades.

      Danger

      If you allow a blade to wear, a slot will form between the sail and flat part of the blade. Eventually a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to you or bystanders.

      • Inspect the blades periodically for wear or damage.

      • Never try to straighten a blade that is bent or weld a broken or cracked blade.

      • Check for bent blades; refer to Checking for Bent Blades.

    Checking for Bent Blades

    1. Rotate the blades until they are positioned as shown in Figure 31.

      g016532
    2. Measure from a level surface to the cutting edges at locations A and B, (Figure 31), and record both dimensions.

    3. Rotate the blades so that their opposite ends are at locations A and B.

    4. Repeat the measurements in step 2 and record them.

      Note: If the difference between dimensions A and B obtained in steps 2 and 4 exceeds 1/8 inch, replace the blades; refer to Removing the Blades.

      Warning

      A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders.

      • Always replace a bent or damaged blade with a new blade.

      • Never file or create sharp notches in the edges or surfaces of a blade.

    Removing the Blades

    Replace the blades when they strike a solid object, are out of balance, bent, or worn. Use only genuine Toro replacement blades.

    1. Use a block of wood to hold each blade steady and turn the blade bolt counterclockwise as shown in Figure 32.

      g232790
    2. Remove each blade as shown in Figure 33.

      g016530
    3. Inspect the pins on the blade drivers for wear and damage.

    Installing the Blades

    Warning

    Incorrectly installing the blades could damage the machine or cause an injury to you or bystanders.

    Install the blades according to the instructions.

    1. Install the first blade so that it is horizontal, along with all mounting hardware as shown in Figure 33.

      Note: Tighten the bolt with your fingers.

      Important: Position the curved ends of the blades to point toward the machine housing. Be sure to nest the raised areas on each blade driver with the recesses in the head of its corresponding spindle, and the pins on the other side of each blade driver with the holes in its corresponding blade.

    2. Steady each blade with a board and turn the blade bolt clockwise with a torque wrench as shown in Figure 34; torque each blade bolt to 82 N∙m (60 ft-lb).

      g232801

      Important: A bolt torqued to 82 N∙m (60 ft-lb) is very tight. Put your weight behind the wrench and tighten the bolt securely. This bolt is very difficult to overtighten.

    3. Rotate the installed blade 1/4 turn until it is vertical, and install the other blade in the same manner as the first (refer to step 1).

      Note: The blades should be perpendicular, forming an inverted “T” as shown in Figure 35.

      g016536
    4. Tighten the second blade; refer to step 2.

    5. Rotate the blades by hand a full 360° turn to ensure that they do not touch.
