    • Keep your hands and feet away from rotating parts. 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 run the PTO with the decks raised above the partial up-stop position.

    • Stop the mower whenever you are not cutting grass.

    • Stop the machine, engage the parking brake, shut off the engine, remove the key, and wait for all moving parts to stop before inspecting the attachment 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.

    • Reduce speed on rough roads and surfaces

    • The mower is heavy. When attached to a tow vehicle, and in the raised position, the weight of the mower affects stability, braking and steering. Exercise caution when transporting between working areas.

    • Never leave a running machine unattended.

    • Before leaving the operating position (including adjusting the height of cut) do the following:

      • Ensure that the PTO is disengaged.

      • Park the machine on a level surface.

      • Engage the parking brake.

      • Lower the mower decks.

      • Shut off the engine and remove the key.

      • Wait for all moving parts to stop before leaving the machine.

    • Use accessories, attachments, and replacement parts approved by The Toro® Company only.

    • For disassembly or repair of all steel PTO driveshaft parts (tubes, bearings, joints, etc.), contact your authorized Toro distributor. Removal of components for repairs and reassembly may damage some parts if not performed with special tools by trained technicians.

    • Do not operate the mower if the PTO or driveshaft guards are missing.

    • Be careful when turning the machine so that the tow vehicle tires do not contact the PTO driveshaft.

    • Secure hydraulic hoses, electrical wiring, ropes, and other items to keep them from contacting the PTO driveshaft guard.

    Slope Safety

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

    • Review and understand the slope instructions in the manual and on the tow vehicle.

    • Evaluate the site conditions to determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.

    • Review the slope instructions listed below for operating the machine on slopes and to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.

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

    • Do not operate a machine under any conditions where traction, steering, or stability are in question.

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

    • 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.

    • Use extreme caution when operating the machine near drop-offs, ditches, embankments, water hazards, or other hazards. 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.

    • Identify hazards at the base of the slope. If there are hazards, mow the slope with a power walk-behind mower.

    • If possible, keep the cutting unit(s) lowered to the ground while operating on slopes. Raising the cutting unit(s) while operating on slopes can cause the machine to become unstable.

    • Use extreme caution with other attachments. These can change the stability of the machine and cause a loss of control. Always keep the machine in gear when going down slopes. Do not coast downhill (applicable only to gear-drive units).

    Servicing the Blades

    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.

    Check the blades daily for sharpness, and for any wear or damage. Sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.

    Danger

    The mower blades are sharp and can injure you.

    Wear heavy leather or cut resistant gloves when servicing with the blades.

    Danger

    A worn or damaged blade can break, and a piece of the blade could be thrown toward you or a bystander, resulting in serious personal injury or death.

    • Inspect the blade periodically for wear or damage.

    • Replace a worn or damaged blade.

    Preparing to Service the Mower Blades

    Note: You need the mower installed to the tow vehicle when servicing the mower blades.

    1. Disengage the PTO, move the machine to a level surface, and engage the parking brake.

    2. Raise and latch the mower decks, shut off the engine, and remove the key (Figure 69).

      g337444

    Checking for Bent Mower Blades

      g337441
    2. Clean the bottom of the mower deck at the area adjacent to the cutting edge at the rear of the blade (Figure 71).

      g255531
    3. Use a combination square to measure the distance between the clean area of the deck and the tip of the cutting edge (Figure 72).

      Record your measurement .

      g255530
    4. Rotate the blade 180° (Figure 72).

    5. Measure the distance between the clean area on the deck and the tip of the cutting edge (Figure 72).

      Record your measurement .

      The difference between measurements that you observed in steps 4 and 6 exceed 3 mm (1/8 inch), the blade is bent, and you must replace the it; refer to Removing the Blades and Installing the Blades

    6. Repeat steps 3 through 5 for the other blades of the mower deck or steps 1 through 6 for the other decks.

    Inspecting the Blades

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the mower blades.
    1. Inspect the cutting edges (Figure 73). If the edges are not sharp or have nicks, remove and sharpen the blades. Refer to Sharpening the Blades.

    2. Inspect the blades, especially the sail area (Figure 73). If you notice any damage, wear, or a slot forming in this area (Figure 73), immediately install a new blade.

      Danger

      If you allow the 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 or death to you or bystanders.

      • Inspect the blade periodically for wear or damage.

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

      • Replace a worn or damaged blade.

      g004653

    Removing the Blades

    Blades must be replaced if a solid object is hit, if the blade is out of balance or is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine Toro replacement blades. Replacement blades made by other manufacturers may result in non-conformance with safety standards.

    Warning

    Contact with a sharp blade can cause serious injury.

    Wear gloves or wrap sharp edges of the blade with a rag.

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

    2. Rotate the blade bolt clockwise to remove the bolt (Figure 74).

      Important: The blade bolts have left-hand threads

      g004480
    3. Remove the anti-scalp plate and blade from the spindle shaft (Figure 74).

    Sharpening the Blades

    Warning

    When sharpening blade, pieces of blade could be thrown and cause serious injury.

    Wear proper eye protection when sharpening blades.

    1. Sharpen the cutting edge at both ends of the blade (Figure 75).

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

      g000276
    2. Check the balance of the blade by putting it on a blade balancer (Figure 76).

      Note: If the blade stays in a horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off the end of the sail area only (Figure 77). Repeat this procedure until the blade is balanced.

      g000277
      g004480

    Installing the Blades

    1. Install the blade onto the spindle shaft (Figure 77).

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

    2. Install the anti-scalp plate and blade bolt (Figure 77).

      Important: The blade bolts have left-hand threads.

    3. Torque the blade bolt to 115 to 150 N∙m (85 to 110 ft-lb).
