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.

The following instructions are adapted from ANSI standard B71.1-2012. All the language within this ANSI standard applies to this machine; however, due to the application of the standard across many different types of products some statements can seem general or misleading. In these instances, Toro has refined the statement to convey the meaning of the standard while better matching the product this Operator's Manual pertains. Safety information in addition to the instructions found in the ANSI standard below can be found in Toro Riding Mower Safety at the end of this section.

General Operation

  • Read, understand, and follow all instructions in the Operator's Manual and on the machine before starting.

  • Do not place your hands or feet near rotating parts or under the machine. Keep clear of the discharge opening at all times.

  • Allow only responsible adults who are familiar with the instructions to operate the machine.

  • Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade.

  • Be sure the area is clear of other people before mowing. Stop the machine if anyone enters the area.

  • Never carry passengers.

  • Do not mow in reverse unless absolutely necessary. Always look down and behind before and while backing up.

  • Be aware of the mower discharge direction and do not point it at anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back toward you. Stop the blade(s) when crossing gravel surfaces.

  • Do not operate the machine without deflector, discharge cover, or entire grass collection system in place and working.

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

  • Never leave a running machine unattended. Always turn off blades, set parking brake, shut off engine, and remove the key before dismounting the machine.

  • Turn off the blades when not mowing. Shut off the engine, wait for all parts to come to a complete stop, and remove the key before cleaning the machine, removing the grass catcher, or unclogging the discharge chute.

  • Operate the machine only in daylight or good artificial light.

  • Do not operate the machine while tired or under the influence of alcohol or drugs.

  • Watch for traffic when operating near or crossing roadways.

  • Use extra care when loading or unloading the machine into a trailer or truck.

  • Wear appropriate clothing including eye protection and substantial, slip-resistant shoes. Tie back long hair. Do not wear jewelry.

  • Always follow the recommendations for any application of counterweights.

  • 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.

Slope Operation

Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

  • Do not mow slopes greater than 15 degrees.

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

  • Choose a low ground speed so that you will not have to stop while operating on a slope.

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

  • Always keep the drive wheels engaged when going down slopes.

  • Reduce speed and use extreme caution on slopes.

  • Do not make sudden turns or rapid speed changes.

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

  • 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 the tires lose traction, stop the machine, disengage the blades, and proceed slowly down the slope.

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

  • Do not try to stabilize the machine by putting your foot on the ground.

  • 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.

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

Children

Tragic accidents can occur if the operator is not alert to the presence of children. 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 mowing area and under the watchful care of another responsible adult, not the operator.

  • Be alert and turn the machine off if children enter the area.

  • Before and while backing or changing direction, look behind, down, and side-to-side for small children.

  • Never carry children on the machine, even with the blades off. Children may fall off and be seriously injured or interfere with the safe operation of machine.

  • Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the mower.

  • Never allow children to operate the machine.

  • Use extra care when approaching blind corners, shrubs, trees, the end of a fence, or other objects that may obscure vision.

Towing Safety

  • Do not attach towed equipment except at the hitch point.

  • Follow the attachment manufacturer's recommendation for weight limits for towed equipment and towing on slopes. Towed weight must not exceed the weight of the machine, operator, and ballast. Use counterweights or wheel weights as described in the attachment, or in the towing machine’s Operator’s Manual.

  • Never allow children or others in or on 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 increases with the weight of the towed load. Travel slowly and allow extra distance to stop.

  • Make wide turns to keep the attachment clear of the machine.

Service

Safe Handling of Gasoline

To avoid personal injury or property damage, use extra care when handling gasoline and other fuels. They are flammable and the vapors are explosive.

  • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

  • Use only an approved container.

  • Never remove the fuel cap or add fuel when the engine is running. Allow the engine to cool before refueling.

  • Never refuel the machine indoors.

  • Never store the machine or fuel container inside where there is an open flame, such as near a water heater or furnace.

  • Never fill containers inside a vehicle or on a truck or trailer with a plastic liner. Always place containers on the ground away from your vehicle before filling.

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

  • Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until the fueling is complete. Do not use a nozzle lock-open device.

  • If you spill fuel on clothing, change your clothing immediately.

  • Never overfill the fuel tank. Replace the fuel cap and tighten it securely.

General Service

  • Never operate a machine inside a closed area. Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you.

  • Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good condition.

  • Never interfere with the intended function of a safety device or to reduce the protection provided by a safety device. Check their proper operation regularly.

  • Keep the machine free of grass, leaves, or other debris buildup. Clean up oil or fuel spills and fuel-soaked debris. Allow the machine to cool before storing it.

  • Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting the machine.

  • Never make any adjustments or repairs with the engine running.

  • Grass catcher components are subject to wear, damage, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace them with the manufacturers' recommended parts, when necessary.

  • Mower blades are sharp and can cut. Wrap the blade(s) or wear thickly-padded gloves and use extra caution when servicing them.

  • Check for proper brake operation frequently. Adjust and service as required.

  • Maintain or replace safety and instruction decals as necessary.

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

Toro Riding Mower Safety

The following list contains safety information specific to Toro products or other safety information that you must know that may not be included in the ANSI standards.

  • Stop the engine, move the motion-control levers to NEUTRAL and outward to the PARK position, disengage the blade-control switch, remove key before and disconnect spark plug wire(s) performing any service, repairs, maintenance or adjustments.

  • Keep 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.

Product Overview

g028411

Become familiar with all the controls in Figure 4 and Figure 5 before you start the engine and operate the machine.

g032603

Ignition Switch

The ignition switch has 3 positions: OFF, RUN, and START. The key turns to START and moves back to RUN upon release. Turning the key to the OFF position stops the engine; however, always remove the key when leaving the machine to prevent someone from accidentally starting the engine (Figure 5).

Throttle Control

The throttle controls the engine speed and it has a continuous variable setting from the SLOW to FAST position ().

Choke Control

Pull up the choke control until it stops to choke the engine (). Push down the choke control for normal engine operation.

Blade-Control Switch (Power Takeoff)

The blade-control switch, represented by a power-takeoff (PTO) symbol, engages and disengages power to the mower blades (Figure 5).

Motion-Control Levers and Park Position

The motion-control levers are speed-sensitive controls of independent wheel motors. Moving a lever forward or backward turns the wheel on the same side forward or in reverse; the wheel speed is proportional to the amount you move the lever. Move the motion-control levers outward from the center to the PARK position when exiting the machine (Figure 14). Always position the motion-control levers into the PARK position when you stop the machine or leave it unattended.

Smart Speed

The Smart Speed™ Control-System lever, located below the operating position, gives you a choice to drive the machine at 3 speed ranges— trim, tow, and mow (Figure 17).

Fuel-Presence Window

You can use the fuel window, located on the left side of the machine, to verify the presence of gasoline in the tank (Figure 6).

g014521

Height-of-Cut Lever

Use the height-of-cut lever to lower and raise the deck from the seated position. Moving the lever up (toward you) raises the deck from the ground and moving the lever down (away from you) lowers the deck toward the ground. Adjust the height-of-cut only while the machine is not moving (Figure 18).

Hour Meter (Model 74723 Only)

The hour meter records the number of hours when you are in the seat and the ignition switch is in the ON position (Figure 7).

g027869

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 face away from nozzle and gas tank or 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

Note: Ensure that the engine is shut off and the motion-control levers are in the PARKED position.

Note: You can use the fuel window to verify the presence of gasoline before filling the tank (Figure 8).

Important: Do not overfill the fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the fuel to expand. Overfilling may result in fuel leakage, damage to the engine, or damage to the emissions system.

g027243

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.

Think Safety First

Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury.

Danger

Operating the machine on wet grass or steep slopes can cause sliding and loss of control.

  • Do not operate on slopes greater than 15 degrees.

  • Reduce speed and use extreme caution on slopes.

  • Do not operate the machine near water.

Danger

Wheels dropping over edges can cause rollovers, which may result in serious injury, death, or drowning.

Do not operate the machine near drop-offs.

g000513

Caution

This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.

    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.

    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. Tie down the machine near the front caster wheels and the rear bumper (Figure 23).

      g027708

    Loading the Machine

    Use extreme caution when loading or unloading the 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 24).

    g027995

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

    Ensure the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 25). 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 will minimize 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.

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

    • Back the machine up ramps and drive it 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.

    Operating Tips

    Fast Throttle Setting

    For best mowing and maximum air circulation, operate the engine at the FAST position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to 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.

    Using the Smart Speed

    The Smart Speed™ Control System lever, located below the operating position, gives you a choice to drive the machine at 3 speed ranges—high, tow, and low. You can benefit from the lower speed setting when maneuvering the machine in tight spaces or operating around delicate landscapes. You can also use the low setting to operate the machine at a high-throttle setting and blade speed while still being able to reduce ground speed to increase the quality of cut.

    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 used in the past is generally the best 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 1/3 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.

    Mowing Direction

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

    Mow 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.

    Avoid 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.

    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.

    When 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.

    Keep 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.

    Blade Maintenance

    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.

    Maintenance

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

    Mower Maintenance

    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 the grass turns it brown at the edges, which slows growth and increases the chance of disease.

    Check the cutting 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, keep extra blades on hand.

    Warning

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

    • Inspect the blade periodically for wear or damage.

    • Replace a worn or damaged blade.

      g006530

    Checking for Bent Blades

    Note: Park the machine on a level surface for the following procedure.

    1. Raise the mower deck to the highest height-of-cut position.

    2. While wearing thickly padded gloves, or other adequate hand protection, slowly rotate the blade to be measured into a position that allows you to effectively measure the distance between the cutting edge and the level surface that the machine is on (Figure 45).

      g014972
    3. Measure from the tip of the blade to the flat surface (Figure 46).

      g014973
    4. Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position (Figure 47).

      g014974
    5. Measure from the tip of the blade to the flat surface (Figure 48).

      Note: The variance should be no more than 3 mm (1/8 inch).

      g014973
      1. If the difference between A and B is greater than 3 mm (1/8 inch), replace the blade with a new blade; refer to Removing the Blades and Installing the Blades.

        Note: If you replace a bent blade with a new blade and the dimension obtained continues to exceed 3 mm (1/8 inch), the blade spindle could be bent. Contact an Authorized Toro Dealer for service.

      2. If the variance is within constraints, move to the next blade.

    6. Repeat steps 1 through 6 for each blade.

    Removing the Blades

    Replace a blade if it hits a solid object, if the blade is out of balance, or if the blade is bent. For best 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 end using a rag or thickly padded glove.

    2. Remove the blade bolt, curved washer, and blade from the spindle shaft (Figure 49).

      g000551

    Sharpening the Blades

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 50).

      Note: Maintain the original angle.

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

      g000552
    2. Check the balance of the blade by putting it on a blade balancer (Figure 51).

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

      Note: If the blade is not balanced, file some metal off only the end of the sail area (Figure 50).

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

    Installing the Blades

    1. Install the blade onto the spindle shaft (Figure 49).

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

    2. Install the curved washer (cupped side toward the blade) and the blade bolt (Figure 49).

    3. Torque the blade bolt to 47 to 88 N·m (35 to 65 ft-lb).
