Operation
 

Before Operation

Before Operation 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.
  • Inspect the area where you will use the machine and remove all objects that could be thrown or could interfere with the operation of the machine.
  • Evaluate the terrain to determine the appropriate equipment and any attachments or accessories required to operate the machine properly and safely.
  • Do not carry passengers on the machine.
  • Become familiar with the safe operation of the equipment, operator controls, and safety signs.
  • Check that operator-presence controls, safety switches, and guards are attached and working properly. Do not operate the machine unless they are functioning properly.
  • 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.
  • Do not operate the machine unless all guards and safety devices, such as the deflectors and the entire grass catcher, are in place and functioning properly. Replace worn or deteriorated parts when necessary.
  • Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operators position. Wait for the machine to cool before servicing, adjusting, fueling, cleaning, or storing it.
    Warning
    Contacting the blade can result in serious personal injury.
    When you shut off the engine, the blade(s) should stop. If not, stop using your machine immediately and contact an Authorized Service Dealer.
     
  • Before mowing, inspect the machine to ensure that the cutting assemblies are working properly.
  • Keep bystanders, particularly children, and pets away from the machine during operation. Shut off the machine and attachment(s) if anyone enters the area.
Fuel Safety
  • Fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.
    • To prevent a static charge from igniting the fuel, place the container and/or machine directly on the ground before filling, not in a vehicle or on an object.
    • Fill the fuel tank outdoors on level ground, in an open area, and when the engine is cold. Wipe up any fuel that spills.
    • Do not handle fuel when smoking or around an open flame or sparks.
    • Do not remove the fuel cap or add fuel to the tank while the engine is running or hot.
    • If you spill fuel, do not attempt to start the engine. Avoid creating a source of ignition until the fuel vapors have dissipated.
    • Store fuel in an approved container and keep it out of the reach of children.
  • Do not overfill the fuel tank. Replace the fuel cap and tighten it securely.
  • In certain conditions during fueling, static electricity can be released, causing a spark that can ignite fuel vapors.
  • Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground and 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 from a fuel-dispenser nozzle.
  • 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.
  • Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.
    • Avoid prolonged breathing of vapors.
    • Keep your hands and face away from the nozzle and the fuel-tank opening.
    • Keep fuel away from your eyes and skin.
  • Clean up any spilled fuel.
  • 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 operate the machine without the entire exhaust system in place and in proper working condition.

Performing Daily Maintenance
Before starting the machine each day, perform the Each Use/Daily procedures listed in the Maintenance Schedule.
Break-In Time
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.
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 Park position.
The safety-interlock system also is designed to shut off the engine whenever the control levers are out of the Park position and you rise from the seat.
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.
 
Testing the Safety-Interlock System
Test the safety-interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately.
  1. Sit on the seat, move the motion-control levers to the Park position, and move the blade-control switch to the On position. Try starting the engine; the engine should not crank.

During Operation

During Operation Safety
  • The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.
  • 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.
  • Do not operate the machine unless all guards and safety devices, such as the deflectors and the entire grass catcher, are in place and functioning properly. Replace worn or deteriorated parts with genuine Toro parts when necessary.
  • Operating engine parts, especially the muffler, can become extremely hot. Severe burns can occur on contact and debris, such as leaves, grass, brush, etc. can catch fire. Keep the engine area free from debris and excessive oil and grease.
  • Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is lethal if inhaled.
  • Operate the machine only in good visibility and appropriate weather conditions. Do not operate the machine when there is the risk of lightning.
  • Start the engine with your feet well away from the blades.
  • Keep your hands and feet away from moving parts. Keep clear of the discharge opening.
  • Keep away from holes, ruts, bumps, rocks, and other hazards. Use care when approaching blind corners, shrubs, trees, tall grass or other objects that may hide obstacles or obscure your view.
  • Do not mow with the discharge deflector raised, removed, or altered unless there is a grass-collection system or mulch kit in place and working properly.
  • Do not mow in reverse unless it is absolutely necessary. Always look down and behind you before moving the machine in reverse.
  • Stop the blades whenever you are not mowing. Slow down the machine, and use caution when crossing surfaces other than grass or when transporting the machine to and from the operating area.
  • Be aware of the mower discharge path and direct the discharge away from others. Avoid discharging material against a wall or obstruction because the material may ricochet back toward you.
  • If the machine strikes an object or starts to vibrate, immediately shut off the engine, remove the key, and wait for all moving parts to stop before examining the machine for damage. 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.
  • Never leave a running machine unattended.
  • Before you leave the operating position, do the following:
    • Park the machine on a level surface.
    • Disengage the power takeoff and lower the attachments.
    • Engage the parking brake.
    • Shut off the engine and remove the key.
    • Wait for all moving parts to stop.
  • Never carry children on the machine.
  • Do not carry children on the machine, even when the blades are not moving. Children could fall off and be seriously injured or prevent you from safely operating the machine. Children who have been given rides in the past could appear in the operating area without warning and be run over or backed over by the machine.
  • Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.
  • Keep children out of the operating area and under the watchful care of a responsible adult other than the operator.
  • Be alert and shut off the machine if children enter the operating area.
  • Before backing up or turning the machine, look down and all around for small children.
  • Do not use the machine as a towing vehicle unless it has a hitch installed. Attach towed equipment to the machine only at the hitch point.
  • Use only accessories and attachments approved by The Toro® Company.
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°.
    • 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.

    3.  Water
    4.  W = Width of the machine
    5.  Keep a safe distance (twice the width of the machine) between the machine and any hazard.
  • 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.
Towing Safety
  • Do not attach towed equipment except at the hitch point.
  • Do not use the machine as a towing vehicle unless it has a hitch installed.
  • Do not exceed the maximum gross towing weight.
  • 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 may increase 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.
Starting the Engine
  1. Start the engine as shown.
    Note: A warm or hot engine may not require choking.
    Important
    Do not engage the starter for more than 5 seconds at a time, otherwise you can damage the starter motor. If the engine fails to start, wait 15 seconds before operating the engine starter again.

    G451067
  1. Disengage the blades by moving the blade-control switch to the Off position.
  2. Move the motion-control levers outward to the Park position.
  3. Move the throttle control to the Slow position and let the engine idle for 1 minute.
  4. Turn the key to the Off position and remove the key.
    Caution
    Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
    Always remove the key and engage the parking brake when leaving the machine unattended.
     
Driving the Machine
Caution
Positioning one lever too far in front of the other causes the machine to spin very rapidly. As a result, you may lose control of the machine, causing personal injury to you and damage to the machine.
Slow down the machine before making sharp turns.
 
The drive wheels turn independently, powered by 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.
  1. Move the motion-control levers down to the center, unlocked position.

Operating the Mower Blade-Control Switch (PTO)
Danger
The rotating blades under the mower deck are dangerous. Blade contact will cause serious injury or death.
Do not put your hands or feet under the mower or mower deck when the blades are engaged.
 
Danger
An uncovered discharge opening allows objects to be thrown toward you or bystanders. Also, contact with the blade could occur. Thrown objects or blade contact will cause serious injury or death.
Do not operate the mower with the discharge deflector raised, removed, or altered unless a grass collection system or mulch kit is in place and working properly.
 
  1. Move the throttle control to the Fast position.
  2. Engage the blade-control switch.
    Graphic
    G450387
  3. Mow as desired.
  4. Disengage the blade-control switch.
    Graphic
    G450388
Side Discharge
The hinged grass deflector disperses clippings to the side and down toward the turf.
Danger
Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and bystanders are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death.
  • Do not remove the grass deflector from the machine, 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.
  • Never try to clear the discharge area or mower blades unless the power takeoff (PTO) is off. Rotate the key to the Off position and remove the key.

For best mowing and maximum air circulation, operate the engine at the Fast position. Air circulation 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.
Avoid Cutting Too Low
When mowing uneven ground, raise the cutting height to slightly higher than normal to avoid scalping the turf. 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.
Cut 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.
Alternate the Mowing Direction
Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.
Mowing Frequency
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.
Mow at Slower Ground Speeds
In certain conditions, mowing at a slower ground speed can improve cut quality.
Avoid Grass Clumps
If you must stop driving forward 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 disengage the mower deck while moving forward.
Keep the Underside of the Mower Deck Clean
Clean clippings and dirt from the underside of the mower deck after each use. Grass and dirt build-up will eventually decrease the cutting quality.
Maintain the Blades
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.
