Before Operation

Before Operation Safety

General Safety

  • Do not 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.

  • Always shut off the machine, remove the ignition key (if equipped), wait for all moving parts to stop, and allow the machine to cool before adjusting, servicing, cleaning, or storing it.

  • Know how to stop the machine and shut off the engine quickly.

  • Check that operator-presence controls, safety switches, and safety protective devices are attached and functioning properly. Do not operate the machine unless they are functioning properly.

  • Inspect the area where you will use the machine, and remove all objects that could interfere with the operation of the machine or that the machine could throw.

  • Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job.

  • Before using, always visually inspect to see that the blades, blade bolts and mower deck are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.

Fuel Safety

  • Use extreme care in handling fuel. It is flammable and its vapors are 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 tank while the engine is running or hot.

  • Do not add or drain fuel in an enclosed space.

  • 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 other appliance.

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

  • 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 the vehicle before filling.

  • Remove equipment from the truck or trailer and refuel it on the ground. If this is not possible, refuel such equipment with a portable container rather than from a fuel-dispenser nozzle.

  • Keep the nozzle in contact with the rim of the fuel tank or container operating at all times until fueling is complete.

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 longer when used as directed by the fuel-stabilizer manufacturer

  • 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 to the bottom of the filler neck.

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

Performing Daily Maintenance

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

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; substantial, slip-resistant footwear; and hearing protection. Tie back long hair and do not wear loose clothing or loose jewelry.

  • 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.

  • Before you start the engine, ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position.

  • Keep bystanders out of the operating area. Stop the machine if anyone enters the area.

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

  • Wet grass or leaves can cause serious injury if you slip and contact the blade. Avoid mowing in wet conditions.

  • Keep your hands and feet away from the cutting unit.

  • Look behind and down before backing up to be sure of a clear path.

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

  • Disengage the drive to the cutting unit and shut off the engine before adjusting the height of cut.

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

  • Do not leave a running machine unattended.

  • Before leaving the operating position (including to empty the catchers or to unclog the cutting units), do the following:

    • Park the machine on level ground.

    • Disengage the cutting unit and lower the attachments.

    • Engage the parking brake.

    • Shut off the machine and remove the ignition key (if equipped).

    • Wait for all moving parts to stop.

    • Shut off the machine and disengage the drive to the cutting unit in the following situations:

      • Before fueling

      • Before clearing blockages

      • Before checking, cleaning, or maintaining the cutting unit

      • After striking a foreign object or if an abnormal vibration occurs. Inspect the cutting unit for damage and make repairs before starting and operating the machine

      • Before leaving the operating position

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

    • Be sure of your footing while using this machine, especially when backing up. Walk; do not run.

    • Never operate with the discharge deflector raised, removed or altered, unless you are using a grass catcher.

    • Never carry passengers on the machine.

    • Do not direct the discharge material toward anyone. Avoid discharging material against a wall or obstruction; material may ricochet toward you. Stop the blade(s) when crossing gravel surfaces.

    • Start the engine carefully according to instructions and with your feet well away from the blade(s) and not in front of the discharge chute.

    • Use extreme caution when reversing or pulling the machine toward you.

    • Stop the blade if you must transport the machine to and from the mowing area and when crossing surfaces other than grass.

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. Before using the machine on a slope, do the following:

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

    • 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.

  • Operate across slopes, never up and down. Avoid operation on excessively steep or wet slopes. Poor footing could cause a slip-and-fall accident.

  • 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 between the machine and any hazard. Use a handheld tool to operate 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.

  • If you lose control of the machine, step away from the direction of travel of the machine.

  • Always keep the machine in gear when going down slopes. Do not coast downhill (applicable only to gear-drive units).

    Adjusting the Axle Height

    Adjust the axle position to the selected height-of-cut setting. Refer to the Height-of-Cut Chart.

    1. Park the machine on a level surface, disengage the PTO, and engage 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. Loosen, but do not remove, the 2 axle-pivot bolts and 2 axle-adjustment bolts (Figure 16).

      g001455
    4. Place a jack under the rear center of the engine frame. Raise the rear end of the engine frame up enough to remove the front 2 axle-adjustment bolts (Figure 16).

      Note: Use jack stands to support the machine.

    5. Raise or lower the engine frame with the jack so that you can install the front 2 axle-adjustment bolts in the desired hole location (Figure 16).

      Note: Use a tapered punch to help align the holes.

    6. Tighten all 4 bolts and lower the machine.

    7. Adjust the control rods and brake linkages as required; refer to Adjusting the Control Rods and Adjusting the Parking Brake.

      Important: You must adjust the control rods and brake linkage when you change the axle positions for proper traction and brake function.

    Adjusting the Caster Position

    1. Using the Height-of-Cut Chart, adjust the caster spacers to match with the axle hole selected (Figure 17).

      g001456
    2. Remove the latch pin, slide the caster from the support, and change the spacers (Figure 17).

    3. Install the caster in the support and insert the latch pin (Figure 17).

    Adjusting the Control Rods

    1. With the wheel drive fully engaged, check the gap between the upper control bar and the fixed bar. The gap needs to be approximately 25 to 32 mm (1 to 1-1/4 inches) as shown in Figure 18.

      Note: The upper control bar and the fixed bar must be parallel in the engaged, relaxed, and brake positions.

      g018809
    2. Check the operation. If adjustment is required, remove the hairpin cotter securing the rod to the upper control bar. Thread the rod in or out of the control rod fitting for proper position and install the control rod into the upper control bar with the hairpin cotter.

    3. After adjusting the control rods, check the parking brake adjustment; refer to Brake Maintenance.

    Mower Deck Maintenance

    Blade Safety

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

    • Inspect the blades periodically for excessive wear or damage.

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

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

    Servicing the Cutting Blades

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

    Before Inspecting or Servicing the Blades

    1. Park the machine on a level surface, disengage the 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 48).

    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 48).

      g006530

    Checking for Bent Blades

    1. Rotate the blades until the ends face forward and backward (Figure 49).

      g001481
    2. Measure from a level surface to the cutting edge, position A, of the blades (Figure 50).

      Note: Note this dimension.

      g001563
    3. Rotate the opposite ends of the blades forward.

    4. Measure from a level surface to the cutting edge of the blades at the same position as in step 1.

      Note: The difference between the dimensions obtained in steps 1 and 2 must not exceed 3 mm (1/8 inch). If this dimension exceeds 3 mm (1/8 inch), the blade is bent and must be replaced; refer to Removing the Blades and Installing the Blades.

    Removing the Blades

    Replace the blades if you hit a solid object or if the blades are out of balance or 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.

    1. Hold the blade bolt with a wrench.

    2. Remove the nut, blade bolt, curved washer, blade, spacers, and thin washer from the spindle (Figure 51).

      g001454

    Sharpening the Blades

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 52).

      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 53).

      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 52).

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

    Installing the Blades

    1. Install the curved washer and then the blade onto the bolt. Select the proper number of spacer(s) for the height of cut, and slide the bolt into the spindle (Figure 51).

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

    2. Install the remaining spacer(s) and secure them with a thin washer and a nut (Figure 51).

    3. Torque the blade bolt to 101 to 108 N∙m (75 to 80 ft-lb).

    Adjusting the Blade Brake

    1. Park the machine on a level surface, disengage the PTO, and engage the parking brake.

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