Safe Operating Practices

This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

Training

  • Read the instructions carefully. Be familiar with the controls and the proper use of the equipment.

  • Never allow children or people unfamiliar with these instructions to use the lawnmower. Local regulations can restrict the age of the operator.

  • Never mow while people, especially children, or pets are nearby.

  • Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property.

  • Do not carry passengers.

  • All drivers should seek and obtain professional and practical instruction. Such instruction should emphasize:

    • the need for care and concentration when working with ride-on machines;

    • control of a ride-on machine sliding on a slope will not be regained by the application of the control levers. The main reasons for loss of control are:

      • insufficient wheel grip, especially on wet grass;

      • being driven too fast;

      • inadequate braking;

      • the type of machine is unsuitable for its task;

      • lack of awareness of the effect of ground conditions, especially slopes;

      • incorrect hitching and load distribution.

Preparation

  • While mowing, always wear substantial, slip-resistant footwear and long trousers.

  • Thoroughly inspect the area where the equipment is to be used and remove all objects which may be thrown by the machine.

  • Warning–Fuel is highly flammable.

    • Store fuel in containers specifically designed for this purpose.

    • Refuel outdoors only and do not smoke while refuelling.

    • Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel while the engine is running or when the engine is hot.

    • If fuel is spilled, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors have dissipated.

    • Replace all fuel tanks and container caps securely.

  • Replace faulty silencers.

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

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

Operation

  • Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, do not operate the machine; seek shelter.

  • Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions.

  • Mow only in daylight or in good artificial light.

  • Before attempting to start the engine, disengage all blade attachment clutches and shift into neutral.

  • Do not use on slopes greater than 15 degrees.

  • Remember there is no such thing as a safe slope. Travel on grass slopes requires particular care. To guard against overturning:

    • do not stop or start suddenly when on a slope;

    • use slow speeds on slopes and during tight turns;

    • stay alert for humps and hollows and other hidden hazards;

  • Use care when pulling loads or using heavy equipment.

    • Use only approved drawbar hitch points.

    • Limit loads to those you can safely control.

    • Do not turn sharply. Use care when reversing.

  • Watch out for traffic when crossing or near roadways.

  • Stop the blades rotating before crossing surfaces other than grass.

  • When using any attachments, never direct discharge of material toward bystanders nor allow anyone near the machine while in operation.

  • Never operate the machine with damaged guards or without safety protective devices in place.

  • Do not change the engine governor settings or overspeed the engine. Operating the engine at excessive speed can increase the hazard of personal injury.

  • Before leaving the operator's position:

    • disengage the power takeoff and lower the attachments;

    • change into neutral and set the parking brake;

    • shut off the engine and remove the key.

  • Disengage drive to attachments, shut off the engine, and disconnect the spark plug wire(s) or remove the ignition key

    • before clearing blockages or unclogging chute;

    • before checking, cleaning or working on the lawnmower;

    • after striking a foreign object. Inspect the lawnmower for damage and make repairs before restarting and operating the equipment; if the machine starts to vibrate abnormally (check immediately).

  • Disengage drive to attachments when transporting or not in use.

  • Shut off the engine and disengage drive to attachment

    • before refuelling;

    • before removing the grass catcher;

    • before making height adjustment unless adjustment can be made from the operator's position.

  • Reduce the throttle setting during engine run-out and, if the engine is provided with a shutoff valve, turn the fuel off at the conclusion of mowing.

Maintenance and Storage

  • Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.

  • Never store the equipment with fuel in the tank inside a building where fumes can reach an open flame or spark.

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

  • To reduce the fire hazard, keep the engine, silencer, battery compartment and fuel storage area free of grass, leaves, or excessive grease.

  • Check the grass catcher frequently for wear or deterioration.

  • Replace worn or damaged parts for safety.

  • If you must drain the fuel tank, this should be done outdoors.

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

  • When machine is to be parked, stored or left unattended, lower the cutting means unless a positive mechanical lock is used.

Toro Riding Mower Safety

The following list contains safety information specific to Toro products or other safety information that you must know that is not included in the CEN standard.

  • Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. Do not run engine indoors or in an enclosed area.

  • Keep your hands, feet, hair and loose clothing away from attachment discharge area, underside of mower and any moving parts while engine is running.

  • Do not touch equipment or attachment parts which may be hot from operation. Allow to cool before attempting to maintain, adjust, or service.

  • Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes and clothing. Protect your face, eyes, and clothing when working with a battery.

  • Battery gases can explode. Keep cigarettes, sparks and flames away from battery.

  • Use only genuine Toro replacement parts to ensure that original standards are maintained.

  • Use only Toro-approved attachments. Warranty may be voided if used with unapproved attachments.

Slope Operation

  • Do not mow slopes greater than 15 degrees.

  • Do not mow near drop-offs, ditches, steep banks or water. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning.

  • Do not mow slopes when grass is wet. Slippery conditions reduce traction and could cause sliding and loss of control.

  • Do not make sudden turns or rapid speed changes.

  • Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water.

  • Reduce speed and use extreme caution on slopes.

  • Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.

  • Watch for ditches, holes, rocks, dips, and rises that change the operating angle, as rough terrain could overturn the machine.

  • Avoid sudden starts when mowing uphill because the mower may tip backwards.

  • Be aware that loss of traction may occur going downhill. Weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking and steering.

  • Always avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly off the slope.

  • Follow the manufacturer's recommendations for wheel weights or counterweights to improve stability.

  • Use extreme care with grass catchers or other attachments. These can change the stability of the machine and cause loss of control.

Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Adding Fuel

The engine runs on clean, fresh diesel fuel with a minimum octane rating of 40. Purchase fuel in quantities that you can use within 30 days to ensure fuel freshness.

Use summer grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter grade diesel fuel (No. 1-D or No. 1-D/2-D blend) below -7°C (20°F). Use of winter grade diesel fuel at lower temperatures provides lower flash point and pour point characteristics, therefore easing startability and lessening chances of chemical separation of the fuel due to lower temperatures (wax appearance, which may plug filters).

Use of summer grade diesel fuel above -7°C (20°F) contributes toward longer life of the pump components.

Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage the engine.

Warning

Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

  • Avoid prolonged breathing of vapors.

  • Keep face away from nozzle and fuel tank or conditioner opening.

  • Keep fuel away from eyes and skin.

Danger

In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.

  • Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold. Wipe up any fuel that spills.

  • Never fill the fuel tank inside an enclosed trailer.

  • Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows fuel to expand. Overfilling may result in fuel leakage or damage to the engine or emission system (if equipped).

  • Never smoke when handling fuel, and stay away from an open flame or where fuel fumes may be ignited by a spark.

  • Store fuel in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of fuel.

  • Always place fuel containers on the ground away from your vehicle before filling.

  • Do not fill fuel containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

  • When practical, remove fuel-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

  • If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a fuel-dispenser nozzle.

  • If a fuel-dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Biodiesel Ready

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur.

Observe the following precautions:

  • The biodiesel portion of the fuel meet specification ASTM D6751 or EN14214.

  • The blended fuel composition should meet ASTM D975 or EN590.

  • Painted surfaces may be damaged by biodiesel blends.

  • Use B5 (biodiesel contend of 5%) or lesser blend in cold weather.

  • Monitor seals, hoses, gaskets in contact with fuel as they may degrade over time.

  • Fuel filter plugging may be expected for a time after converting to biodiesel blends.

  • Contact your distributor if you wish for more information on biodiesel.

Filling the Fuel Tank

Note: Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the gasoline to expand.

  1. Shut the engine off and set the parking brake.

  2. Clean around each fuel-tank cap and remove the cap. Fill the fuel tank to the bottom of the filler neck. This space in the tank allows the fuel to expand. Do not fill the fuel tank completely full.

  3. Install the fuel-tank cap securely. Wipe up any fuel that may have spilled.

  4. If possible, fill the fuel tank after each use. This minimizes possible buildup of condensation inside the fuel tank.

Checking the Engine-Oil Level

Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level.

Switching the Fuel Tanks

Important: Do not run the machine out of fuel. This may cause engine damage and require the fuel system to be checked.

The fuel-selector valve is located behind the left side of the seat.

The unit has 2 fuel tanks. One tank is on the left side and the other on the right side. Each tank connects to the fuel-selector valve. From there a common fuel line leads to the engine (Figure 6).

To use the left side fuel tank rotate the fuel-selector valve to the left-hand location. To use the right side fuel tank rotate the fuel-selector valve to the right-hand location (Figure 6)

Close the fuel-selector valve before transporting or storing machine.

    1. Disengage the power takeoff (PTO) and turn the ignition key to off. Move the levers to NEUTRAL-LOCK position, apply the parking brake, and remove the key.

    2. Rotate the bypass valves counterclockwise 1 turn. This allows hydraulic fluid to bypass the pump enabling the wheels to turn (Figure 24).

      Important: Do not rotate the bypass valves more than 1 turn. This prevents valves from coming out of the body and causing fluid to run out.

    3. Disengage parking brake before pushing the machine.

    Changing to Machine Operation

    Rotate the bypass valves clockwise 1 turn to operate the machine (Figure 24).

    Note: Do not over tighten the by-pass valves.

    The machine will not drive unless bypass valves are turned in.

    Operating with the Overheat Sensor

    This machine has a sensor that turns OFF the mower deck when the engine overheats. When the engine overheats, the audible alarm and light alarm turns ON along with the mower deck turning OFF.

    If the mower deck turns OFF automatically because of overheating, drive the machine to a safe area and to a truck or trailer.

    If the machine overheats, ensure that the area around the engine and radiator is clear of any debris. Turn the engine off and allow it to cool down before you engage the mower deck. If the engine continues to overheat, take your machine to an Authorized Service Dealer.

    Transporting the Machine

    Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary lighting and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets or bystanders avoid injury.

    To transport the machine:

    • Lock the brake and block the wheels.

    • Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes.

    • Secure a trailer to the towing vehicle with safety chains.

      Warning

      Driving on the street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury.

      Do not drive machine on a public street or roadway.

    Loading the Machine

    Use extreme caution when loading or the unloading machine onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Back the machine up the ramp and drive it forward down the ramp (Figure 25).

    g028043

    Important: Do not use narrow individual ramps for each side of the machine.

    Ensure that the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 26). On flat ground, this requires a ramp to be at least 4 times as long as the height of the trailer or truck bed to the ground. A steeper angle may cause mower components to get caught as the machine moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control. If you are loading the machine on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This minimizes the ramp angle.

    Warning

    Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death.

    • Use extreme caution when operating a machine on a ramp.

    • Ensure that the ROPS is in the up position and use the seat belt when loading or unloading the machine. Ensure that the ROPS clears the top of an enclosed trailer.

    • Use only a full-width ramp; do not use individual ramps for each side of the machine.

    • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.

    • Ensure that the length of ramp is at least 4 times as long as the height of the trailer or truck bed to the ground. This ensures that ramp angle does not exceed 15 degrees on flat ground.

    • Back up ramps and drive forward down ramps.

    • Avoid sudden acceleration or deceleration while driving the machine on a ramp as this could cause a loss of control or a tip-over situation.

    g027996

    5. Return the stand to its REST position (Figure 27).

    Operating Tips

    Using the Fast Throttle Setting

    For best mowing and maximum air circulation, operate the engine at the FAST throttle position. Air is required to thoroughly cut grass clippings, so do not set the height of cut so low as to totally surround the mower in uncut grass. Always try to have 1 side of the mower free from uncut grass, which allows air to be drawn into the mower.

    Cutting a Lawn for the First Time

    Cut the grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. However, the cutting height you have used in the past is generally the best to use. When cutting grass longer than 15.24 cm (6 inches) tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.

    Cutting 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.

    Alternating the Mowing Direction

    Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.

    Mowing at Correct Intervals

    Normally, mow every 4 days. However, grass grows at different rates at different times. To maintain the same cutting height, which is a good practice, 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.

    Adjusting the Cutting Speed

    To improve cut quality, use a slower ground speed in certain conditions.

    Avoiding Cutting Too Low

    If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure that uneven turf is not cut too short.

    Cutting Long Grass

    If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting.

    Stopping

    If you must stop the forward motion of the machine 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.

    Keeping the Underside of the Mower Clean

    Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.

    Maintaining 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 cutter blades daily 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 immediately with a genuine Toro replacement blade.

      g001905

    Servicing the Cutting 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 cutter blades daily 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 immediately with a genuine Toro replacement blade. For convenient sharpening and replacement, you may want to keep extra blades on hand.

    Danger

    A worn or damaged blade can break, and a piece of the blade could be thrown into the operator's or bystander's area, resulting in serious personal injury or death.

    • Inspect the blade periodically for wear or damage.

    • Replace a worn or damaged blade.

    1. Disengage the PTO, move the motion-control levers to the NEUTRAL-LOCK position, and set 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. Rotate the blades until the ends face forward and backward (Figure 79). Measure from a level surface to the cutting edge, position A, of the blades (Figure 79). Note this dimension.

      g003177
    4. Rotate the opposite ends of the blades forward.

    5. Measure from a level surface to the cutting edge of the blades at the same position as in step 3 above. The difference between the dimensions obtained in steps 3 and 4 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.

      Warning

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

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

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

    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. Remove the blade bolt, spring disk and blade from the spindle shaft (Figure 82).

    Sharpening the Blades

    Warning

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

    Wear proper eye protection when sharpening blade.

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 80). 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 81). 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 82). Repeat this procedure until the blade is balanced.

      g000277

    Installing the Blades

    1. Install the blade onto the spindle shaft (Figure 82).

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

    2. Install the curved washer and blade bolt. The curved washer cone must be installed toward the bolt head (Figure 82). Torque the blade bolt to 115 to 150 N∙m (85 to 110 ft-lb).
