Safety

This machine meets or exceeds the B71.1-2003 specifications of the American National Standards

Institute, in effect at the time of production. However, improper use or maintenance by the

operator or owner can result in injury. 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 from ANSI standard B7I.I-2003. All the language within this ANSI standard applies to this machine; however, due to the application of the standard across ma W different types of products

some statements can seem general or misleading. In these instances, _[bro has refined the statement to convey

the meaning of the standard while better matching the product this Operator's Mazual pertains. Safety

information in addition to the instructions found in the ANSI standard below can be found in _fbro 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.

• iMlow 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 necessar> Always look down and behind before and while

backing up.

• Be aware of the mower discharge direction and do

not point it at awone. 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 malting turns. Look behind and to the side before changing

directions.

• Never leave a running machine unattended. Always turn off blades, set parldng 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 tiding mower safely enough to protect themselves and others from serious injur>

• Always follow the recommendations for aW application o f 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 traenon 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 shp 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 oft- the slope.

• Use extreme care with grass catchers or other attachments. These can change the stability of the

machine and cause loss of control.

• 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

A hitch kit is available for this machine and can be

obtained by contacting an Authorized Toro Dealer. Do not tow without first installing this manufacturer

approved hitch. The following guidelines apply when towing with the approved hitch kit installed.

• Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point.

• Follow the manufacturer's recommendation for weight limits for towed equipment and towing on

slopes.

• Never allow children or others in or on towed equipment.

• On slopes, the weight of the towed equipment may cause loss of traction and 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 injur 5 death

or drowning.

• Use a walk behind mower and/or a hand trimmer

near drop-oft_, 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 activit> 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 oft-if children enter the area.

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

• Travel slowly and allow extra distance to stop.

Controls

Become familiar with all of the controls in Figure 4, Figure 5, and Figure 6 before you start the engine and operate the machine.

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 i7). Always position the motion control levers

into the park position when you stop the machine or leave it unattended.

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

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.

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.

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

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.

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.

Filling the Fuel Tank

• 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

Use UNLEADED Regular Gasoline suitable for

automotive use (87 pump octane minimum). Leaded

regular gasoline may be used if unleaded regular is not

available. Important: Never use methanol, gasoline

containing methanol, or gasohol containing more than 10 percent ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

Using Stabilizer/Conditioner

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

Make sure the engine is shut off and the motion controls are in the park position. Tank maximum capacity is 2.9 gallons.

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 or damage to

the engine or emission system.

1. (;lean around the fuel tank cap and remove the cap.

Note: You can use the fuel window to veri_

the presence of gasoline before filling the tank

(Figure 10).

Slowly add regular, unleaded gasoline until the fuel reaches the base of the filler neck (Figure i0).

• Keeps gasoline fresh during storage of 30 days or less. For longer storage it is recommended that the

fuel tank be drained.

• (;leans 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.

Gasoline/Alcohol blends

Gasohol (up to 10 percent ethyl alcohol, 90 percent unleaded gasoline by volume) is approved for fuel use by the engine manufacturer. Other gasoline/alcohol

blends, such as E85, are not approved.

Driving

Driving the machine benefits from an understanding of what zero turn radius mower means. The drive wheels

turn independentl B powered by hydraulic motors on each axle; hence one side can turn in reverse while

the other turns forward causing the machine to spin rather than turn. This vastly improves the machine maneuverability but may require some adjustment if

the operator is unfamiliar.

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.

Using the Smart Speed TM Control

System

The Smart Speed TM Control System lever, located below the operating position (Figure 18), gives the operator a choice to drive the machine at two ground speed ranges, high and low.

Pushing the Machine by Hand

Important: Always push the machine by hand.

Never tow the machine because damage may

occur.

This machine has an electric brake mechanism and to push the machine the ignition key needs to be in the

Run position. The battery needs to be charged and

functioning for the electric brake to be disengage.

To Push the Machine

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

2. Move the motion control levers outward to park position, stop the engine, and wait for all moving parts to stop before leaving the operating position.

3. Raise the seat to locate the bypass levers behind the batter}; on the frame.

Move the bypass levers forwards and then out to lock them in place as shown in Figure 25 to disengage the wheel motors. Repeat this for each

lever.

. Lower the scat and move the motion control levers

inward to the neutral position and turn the ignition key to the run position. Do not start the machine.

The machine is now able to be pushed by hand.

charge.

If the machine fails to move the electric brake may still be engaged. If necessary the electric

brake can be released manually. Refer to the Releasing the Electric Brake (page 36) procedure in

Drive Maintenance.

To Operate the Machine

Move the bypass levers inward and push them back in the horizontal slot (Figure 25) to engage the wheel

motors.

Grass Deflector

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

Cut 1/3 of the Grass Blade

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).

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 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.

Using the Smart Speed TM Control

System

It is best to cut only about i/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 mowing direction to keep the grass standing straight. This also helps disperse clippings which

enhances decomposition and fertilization.

Mow at Correct Intervals

Normall3; mow every fi)ur days. But remember, grass grows at different rates at different times. So

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 two 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.

The Smart Speed TM Control System lever, located below the operating position, gives the operator a

choice to drive the machine at two speed ranges, high

and low. An operator can benefit from the lower speed

setting when maneuvering the machine in tight spaces

or operating around delicate landscapes. The low

setting can also be used to operate the machine at a high throttle setting and blade speed while still being

able to reduce ground speed to increase quality of cut.

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.

When Stopping

If the machine's forward motion must be stopped 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, cutting quality will eventually become unsatisfactor}.

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 aW wear or damage. File

down aW nicks and sharpen the blades as necessar> If

a blade is damaged or worn, replace it immediately with

a genuine _l-bro replacement blade.

Maintenance

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