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 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 the operator. 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, stop engine, and remove key before dismounting.

  • Turn off blades when not mowing. Stop 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 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.

  • Always wear eye protection when operating the mower.

  • Data indicates that operators, age 60years and above, are involved in a large percentage of riding mower-related injuries. Operators should evaluate their ability to operate the riding mower safely enough to protect themselves and others from serious injury.

  • 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.

Close section

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 15degrees.

  • 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 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. Do not shift to neutral and coast downhill.

  • 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 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, stop the machine, disengage the blades and proceed slowly off 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.

Close section

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, even with the blades off. They may fall off and be seriously injured or interfere with safe machine operation.

  • 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 or block your view of a child.

Close section

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 pulling machine 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.

  • 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 fuel container.

  • Never remove the gas 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 gas-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 fuel is spilled on clothing, change clothing immediately.

  • Never overfill the fuel tank. Replace gas cap and tighten 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 reduce the protection provided by a safety device. Check their proper operation regularly.

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

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

  • 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 with 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.

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 which 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 a gasoline 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.

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 spillage 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 gas stabilizer/conditioner to the gas.

    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.

Close section

Filling the Fuel Tank

Note: Ensure that the engine is shut off and the motion controls are in the parked position.

Note: You can use the fuel window to verify the presence of gasoline before filling the tank (Figure 7).

Important: Do not overfill 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.

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.

Close section

Think Safety First

Operating Safety

Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets, or bystanders avoid injury.

Danger

Mowing on wet grass or steep slopes can cause sliding and loss of control.

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

A loss of traction is a loss of steering control.

To avoid loss of control and possibility of rollover:

  • Do not mow near drop-offs or near water.

  • Do not mow slopes greater than 15degrees.

  • Reduce the speed and use extreme caution on slopes.

  • When mowing slopes, gradually work from lower to higher areas on the incline.

  • Avoid sudden turns or rapid speed changes.

  • Turn up, into an incline when changing directions on slopes. Turning down the slope reduces traction.

  • Attachments change the handling characteristics of the machine. Use extra caution when using attachments with the machine.

Driving the Machine

This machine has the characteristics of both a garden tractor and a zero-turn machine. Like a garden tractor, the machine has a foot pedal that controls the forward and reverse motion along with the speed, and it has a steering wheel that controls the direction and the turning radius. Like a zero-turn machine, the rear drive wheels operate independently of each other, enabling you to make sharp turns and to turn in different directions quickly. These characteristics vastly improve the maneuverability of the machine, but they may also require you to practice driving if you are unfamiliar with this type of machine.

Warning

The machine can spin very rapidly. The operator may lose control of the machine and cause personal injury or damage to the machine.

  • Use caution when making turns.

  • Slow the machine down before making sharp turns.

The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Placing the throttle control in the Fast position can be best for performance. For most applications, operating in the full-throttle position is desirable.

Driving Forward or Backward

  1. Move the throttle to the fast position.

  2. Place your foot onto the traction-control pedal and slowly press the top of the pedal to go forward, or press on the bottom of the pedal to move backward (Figure 13).

    Note: The farther you move the pedal in either direction, the faster the machine will move in that direction.

    g027750
  3. To slow down, release the pressure on the traction-control pedal.

Close section
Close section

Stopping the Machine

To stop the machine, release the traction-control pedal, disengage the blade-control switch, ensure the throttle is in the fast positions, set the parking brake and turn the ignition key to off.

Note: Remember to remove the key from the ignition switch.

Warning

Children or bystanders may be injured if they move or attempt to operate the mower while it is unattended.

Always remove the ignition key and set the parking brake when leaving the machine unattended, even if just for a few minutes.

Close section

Mowing in Reverse

The machine has an interlock feature that prevents the mower deck from mowing while the machine is traveling in reverse. If you shift into reverse with the PTO engaged, the PTO will stop. If you need to mow while in reverse gear, you can temporarily deactivate this interlock.

Note: Do not mow while backing up unless it is absolutely necessary.

Danger

A child or bystander could be backed over by a riding mower with blades engaged and cause serious personal injury or death.

  • Do not mow in reverse unless absolutely necessary.

  • Always look backward and down before backing up.

  • Use the KeyChoice switch only if you are certain no children or other bystanders will appear in the mowing area.

  • Always remove both the ignition and KeyChoice keys and put them in a safe place out of the reach of children or unauthorized users when leaving the unit unattended.

If you are certain that you can safely mow or operate an attachment in reverse, complete the following procedure:

  1. Insert the KeyChoice key into the KeyChoice switch (Figure 6).

  2. Engage the PTO.

  3. Turn the KeyChoice key clockwise until it stops and release it.

    Note: A red light illuminates on the console to serve as a reminder that the interlock has been deactivated.

  4. Perform the mowing.

  5. When finished mowing, remove the KeyChoice key (Figure 6).

    Note: Once you deactivate the interlock, it stays in this mode—with your mower blade or PTO powered attachment operating whenever you back up—and the console light stays on until you either disengage the PTO or turn off the engine.

Grass Deflector

The mower has a hinged grass deflector that 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 others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will 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 discharge area or mower blades unless you move the blade-control switch to Off and rotate the ignition key to Off. Also remove the key and pull the wire off the spark plug(s).

Close section

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 machine on a public street or roadway.

To transport the machine:

  1. If 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. Stop 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 19).

    Note: Avoid the steering components when tying down the machine at the front caster wheels.

    g027708
Close section

Loading the Machine

Use extreme caution when loading or unloading machines onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Back up ramps and drive forward down ramps (Figure 20).

g028294

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 21). On flat ground, this requires a ramp to be at least four times (4X) 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 unit moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control. If loading 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 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 four times (4X) 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 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.

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 by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.

Close section

Cutting a Lawn for the First Time

Cut 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 one to use. When cutting grass longer than six inches tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.

Close section

Cutting 1/3 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.

Close section

Mowing Direction

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

Close section

Mowing at Correct Intervals

Normally, mow every 4 days. But, remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, and 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.

Close section

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.

Close section

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.

Close section

Stopping

If you must stop the machine's forward motion 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 you can disengage the mower deck while moving forward.

Close section

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.

Close section

Maintaining the Blade(s)

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 immediately with a genuine Toro replacement blade.

    The mower deck must be checked for bent blades prior to leveling; any bent blades must be removed and replaced. Refer to the Checking for Bent Bladesbefore continuing.

    The mower deck must be leveled side-to-side first then the front to rear slope can be adjusted.

    Requirements:

    Leveling from Side to Side

    1. Park the machine on a level surface and disengage the blade-control switch.

    2. Ensure the parking brake is engaged, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

    3. Set the height-of-cut lever to middle position.

    4. Carefully rotate the blade(s) so that they are all side to side (Figure 53).

      g005278
    5. Measure between the outside cutting edges and the flat surface (Figure 53). If both measurements are not within 5mm (3/16inch), an adjustment is required; continue with this procedure.

    6. Move to the left side of the machine.

    7. Loosen the side locking nut.

    8. Raise or lower the left side of the mower deck by rotating the rear nut. (Figure 54).

      Note: Rotate the rear nut clockwise to raise the mower deck; rotate the rear nut counter-clockwise to lower the mower deck.

      g027588
    9. Check the side-to-side adjustments again. Repeat this procedure until the measurements are correct.

    10. Continue leveling the deck by checking the front-to-rear blade slope; refer to Adjusting the Front-to-Rear Blade Slope.
