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 lawn mower. 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. Tie back long hair. Do not wear jewelry.

  • Thoroughly inspect the area where you will use the equipment and remove all objects which the machine may throw at you.

  • Warning–Fuel is highly flammable.

    • Store fuel in containers specifically designed for this purpose.

    • Refuel the machine 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 you spill fuel, 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 the 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 the transmission into neutral.

  • Do not use on slopes greater than 15 degrees.

  • Remember that 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 the machine.

  • 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.

  • Keep all nuts, bolts and screws tight to be sure that 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 the machine 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, do it outdoors.

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

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 the engine indoors or in an enclosed area.

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

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

  • 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 maintain the original standards.

  • Use only Toro-approved attachments. You may void the warranty if you use 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 a 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 backward.

  • 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 a loss of control.

Operation

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

Adding 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 a fuel stabilizer is used.

  • Do not add oil to gasoline.

Danger

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

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

  • Never fill the fuel tank inside an enclosed trailer.

  • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

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

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

  • Do not operate without entire exhaust system in place and in proper working condition.

Danger

In certain conditions during fueling, static electricity can be released, causing a spark that can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.

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

  • Do not fill gasoline 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 gas-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 gasoline-dispenser nozzle.

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

Warning

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

  • Avoid prolonged breathing of vapors.

  • Keep your face away from nozzle, gas tank, and conditioner bottle opening.

  • Avoid contact with skin; wash off spills with soap and water.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

  • Keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.

  • 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 gasoline stabilizer/conditioner to the gasoline.

    Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. 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 level ground.

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

  3. Clean around the fuel-tank cap.

  4. Fill the fuel tank to the bottom of the filler neck (Figure 7).

    Note: Ensure that there is empty space in the tank to allow the gasoline to expand

    Note: Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck.

    g027726

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.

Breaking in a New Machine

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.

    Adjusting the Flow-Baffle-Cam Locks

    This procedure is applicable only to machines with flow-baffle locks. Certain models have nuts and bolts in place of the flow-baffle locks and can be adjusted the same.

    You can adjust the mower-discharge flow for different types of mowing conditions. Position the cam locks and baffle to achieve the best quality of cut.

    1. Disengage the blade-control switch (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. To adjust the cam locks, swing the lever up to loosen the cam lock (Figure 30).

    4. Adjust the baffle and cam locks in the slots to the desired discharge flow.

    5. Swing the lever back over to tighten the baffle and cam locks (Figure 30).

    6. If the cam locks do not lock the baffle into place or it is too tight, loosen the lever and then rotate the cam lock. Adjust the cam lock until you achieve the desired locking pressure.

      g027727

    Positioning the Flow Baffle

    The following figures are only recommendations for use. Adjustments vary by grass type, moisture content, and height of grass.

    Note: If the engine power draws down and the mower ground speed is the same, open up the baffle.

    Position A

    This is the full rear position. Use this position for the following.

    • Short, light grass mowing conditions.

    • Dry conditions.

    • Smaller grass clippings.

    • Propelling grass clippings farther away from the mower.

      g005832

    Position B

    Use this position when bagging. Always align it with the blower opening.

    g005833

    Position C

    This is the full open position. Use this position for the following:

    • Tall, dense grass mowing conditions.

    • Wet conditions.

    • Lowering the engine power consumption.

    • Increased ground speed in heavy conditions.

      g005834

    Note: This position is similar to the benefits of the Toro SFS mower.

    Positioning the Seat

    The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable.

    To adjust the seat, move the lever sideways to unlock seat (Figure 34).

    g019768

    Using the Drive-Wheel Release Valves

    Warning

    Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury.

    Shut off the engine, remove the key, and wait for all moving parts to stop before accessing the drive-wheel release valves.

    Warning

    The engine and hydraulic drive units can become very hot. Touching a hot engine or hydraulic drive units can cause severe burns.

    Wait for the engine and hydraulic drive units to cool completely before accessing the drive-wheel release valves.

    The drive-wheel release valves are located in the back of each hydraulic drive unit, under the seat.

    Note: Make sure that the release valves are in the fully horizontal position when operating the machine or severe damage to the hydraulic system can occur.

    1. Disengage the blade-control switch (PTO) and turn the ignition key to off. Move the levers to the NEUTRAL-LOCK position and apply the parking brake. Remove the key.

    2. Rotate the release-valve levers vertically to push the machine (Figure 36).

      Note: This allows hydraulic oil to bypass the pump, enabling the wheels to turn.

    3. Disengage the parking brake before pushing the machine.

      g008957
    4. Rotate the release-valve levers horizontally to run the machine (Figure 36).

    Using the Side Discharge

    The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.

    Danger

    Without a grass deflector, discharge cover, or a complete grass-catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris cause injury or death.

    • Never remove the grass deflector from the mower 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 you move the blade-control switch (PTO) to the OFF position, rotate the ignition key to the OFF position, and remove the key.

    • Make sure that the grass deflector is in the down position.

    Transporting the Machine

    Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, 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.

    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 the machine on a public street or roadway.

    To transport the machine:

    1. If you are using a trailer, connect it to the towing vehicle and connect the safety chains.

    2. If applicable, connect the trailer brakes.

    3. Load the machine onto the trailer or truck.

    4. Shut off the engine, remove the key, set the brake, and close the fuel valve.

    5. Use the metal tie-down loops on the machine to securely fasten the it to the trailer or truck with straps, chains, cable, or ropes (Figure 37).

      g009028

    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 ramps and drive it forward down the ramps (Figure 38).

    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 39). 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 a 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 the machine up the ramps and drive it forward down the 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.

    g027996

    Using the Z Stand

    The Z Stand raises the front end of the machine to allow you to clean the mower and remove the blades.

    Warning

    The machine could fall onto someone and cause serious injury or death.

    • Use extreme caution when operating the machine on the Z Stand.

    • Use only for cleaning the mower and removing the blades.

    • Do not keep the machine on the Z Stand for extended periods of time.

    • Always turn the engine off, set the parking brake, and remove the key before performing any maintenance to the mower.

    Driving up onto the Z Stand

    Important: Use the Z Stand on a level surface.

    1. Raise the mower to the transport position.

    2. Remove the bracket pin (Figure 40).

      g010172
    3. Raise the latch.

    4. Slowly drive backward off the stand.

    5. Return the stand to its rest position (Figure 40).

    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 that 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, the cutting quality eventually becomes unsatisfactory.

    Maintaining the Blade

    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.

    Mower Deck Maintenance

    Leveling the Mower Deck

    Setting Up the Machine

    Note: Ensure that the mower deck is level before matching the height of cut (HOC).

    1. Position the mower on a flat surface.

    2. Disengage the blade-control switch (PTO), move the motion-control levers to the NEUTRAL-LOCK position, and set the parking brake.

    3. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

    4. Check the pressure of the drive tires.

      Note: Proper inflation pressure for the tires is 90 kPa (13 psi).

    5. Position the mower deck to the 76 mm (3 inch) height-of-cut position.

    Leveling the Deck

    1. Position the mower on a flat surface.

    2. Shut off the engine, wait for all moving parts to stop, remove the key, and engage the parking brake.

    3. Check the tire pressure in the drive tires.

      Note: Proper inflation pressure for the tires is 90 kPa (13 psi).

    4. Position the transport lock in the latching position.

    5. Push the deck-lift pedal all the way forward so that the deck latches at the 14 cm (5-1/2 inches) transport position (Figure 93).

      g027343
    6. Insert the height adjustment pin into the 7.6 cm (3 inches) cutting height location.

    7. Release the transport lock and allow the deck to lower to the cutting height.

    8. Raise the discharge chute.

    9. On both sides of the deck, measure from the level surface to the front tip of the blade (Postion A) as shown in Figure 94.

      Note: The measurement should read 7.6 mm (3 inches)

      g009196
    10. Fine-tune the adjustment nut on the front deck-lift assembly by turning it (Figure 95).

      Note: To increase the height, turn the adjustment nut clockwise; to decrease the height, turn the nut counterclockwise.

      g027344

      Note: To increase the height, turn the adjustment nut clockwise; to decrease the height, turn the nut counterclockwise.

      Note: If the front deck links do not have enough adjustment to achieve accurate cut height, you can utilize the single-point adjustment to gain more adjustment.

      g010251
    12. To adjust the single-point system, loosen the 2 bolts at the bottom of the height-of-cut plate (Figure 97).

      g027345
    13. If the deck is too low, tighten the single-point adjustment bolt by rotating it clockwise. If the deck is too high, loosen the single point adjustment bolt by rotating it counterclockwise (Figure 98).

      Note: Loosen or tighten the single-point adjustment bolt enough to move the height-of-cut plate mounting bolts at least 1/3 the length of the available travel in their slots. This will gain some up and down adjustment on each of the 4 deck links.

    14. Tighten the 2 bolts at the bottom of the height-of-cut plate (Figure 98).

      Note: In most conditions, the back blade tip should be adjusted 6.4 mm (1/4 inch) higher than the front.

      g017036
    15. Torque the 2 bolts to 37 to 45 N∙m (27 to 33 ft-lb).

    16. On both sides of the deck, measure from the level surface to the back tip of the blade (position B) as shown in Figure 94.

      Note: The measurement should read 8.3 cm (3-1/4 inches)

    17. Fine-tune the screw adjuster by turning it to get 8.3 mm (3-1/4 inches) height (Figure 96).

      Note: To increase the height, turn the adjustment nut clockwise; to decrease, turn counterclockwise.

    18. Measure until all 4 sides are the correct height.

    4. Measure from a level surface to the cutting edge, position A, of the blades (Figure 100).

      g000975
    5. Rotate the opposite ends of the blades forward.

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

      Note: The difference between the dimensions obtained in steps 4 and 6 must not exceed 3 mm (1/8 inch).

      Note: If this dimension exceeds 3 mm (1/8 inch), the blade is bent and must be replaced.

      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.

      • Do not file or create sharp notches in the edges or surfaces of the blade.

    Removing the Blades

    Replace a blade if it hits an object, if the blade is out of balance, or if the blade 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 nonconformance with safety standards.

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

    2. Remove the blade bolt, curved washer, and blade from the spindle shaft (Figure 101).

      g004536

    Sharpening the Blades

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 102).

      Note: Maintain the original angle.

      Note: The blade retains balance if you remove the same amount of material from both cutting edges.

      g000276
    2. Check the balance of the blade by putting it on a blade balancer (Figure 103).

      Note: If the blade stays in a horizontal position, the blade is balanced and ready to use.

      g000277
    3. If the blade is not balanced, file some metal off the end of the sail area only (Figure 101).

    4. Repeat this procedure until the blade is balanced.

    Installing the Blades

    1. Install the blade onto the spindle shaft (Figure 104).

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

    2. Install the spring disk and blade bolt (Figure 104).

      Note: Install the spring-disk cone toward the bolt head.

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

      g004536

    Removing the Mower Deck

    Before servicing or removing the mower deck, lock out the spring-loaded deck arms.

    Warning
