Safety

To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER-"personal safety instruction." Failure

to comply with the instruction may result in personal injury or death.

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 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 60 years 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.

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 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 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.

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.

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 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 to 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 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 the key and disconnect the spark plug wire(s) before 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.

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

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

Ignition Switch

The ignition switch has three positions, Off, Run and Start. The key will turn to Start and move back to Run upon release. Turning the key to the Off position will stop the engine; however, always remove the key when leaving the machine to prevent someone from accidentally starting the engine (Figure 5).

Controls

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

Throttle/Choke Control

The throttle and choke is combined into one control lever. The throttle controls the engine speed and it has a continuous variable setting from Slow to Fast. Engage the choke by moving the lever past the Fast setting until it stops (Figure 5).

Blade Control Switch (Power Take-Off)

The blade control switch, represented by a power take-off (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; wheel speed is proportional to the amount the lever is moved. Move the control levers outward from the center to the park position and exit the machine (Figure 16). Always position the motion control levers into the park position when you stop the machine or leave it unattended.

Smart Speed™ Control System Lever

The Smart Speed™ Control System lever, located below the operating position, gives the operator a choice to drive the machine at two speed ranges, high and low (Figure 6).

Height-of-Cut Lever

The height of cut lever allows the operator to lower and raise the deck from the seated position. When the lever is moved up, toward the operator the deck is raised from the ground and when moved down, away from the operator it is lowered toward the ground. Only adjust the height of cut while machine is not moving (Figure 4).

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

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 15 degrees.

•Reduce 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.

Fuel Safety

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 fuel reaches the base 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 opening.

•Keep gas away from eyes and skin.

Understanding the Safety Interlock

System

WARNING

If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury.

•Do not tamper with the interlock switches.

•Check the operation of the interlock switches daily and replace any damaged switches before operating the machine.

The safety interlock system is designed to prevent the engine from starting unless:

•The blades are disengaged.

•The motion control levers are in the park position.

The safety interlock system also is designed to stop the engine whenever the control levers are out of the park position and you rise from the seat.

Before Starting

Recommended 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.

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.

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.
