Safety

This machine meets or exceeds the B71.1–1998

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

The following instructions are from ANSI standard

B71.1—1998.

This product is capable of amputating hands and feet

and throwing objects. Always follow all safety

instructions to avoid serious injury or death.

General Operation

•Read, understand, and follow all instructions in

the operator’s manual and on the machine before

starting.

•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.

•Be aware of the mower discharge direction and

do not point it at anyone. Do not operate the

mower without either the entire grass catcher or

the guard in place.

•Slow down before turning.

•Never leave a running machine unattended.

Always turn off blades, set parking brake, stop

engine, and remove keys before dismounting.

•Turn off blades when not mowing.

•Stop the engine before removing the grass

catcher or unclogging the chute.

•Mow 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 safety goggles or safety glasses

with side shields when operating mower.

•Data indicates that operators, age 60 years and

above, are involved in a large percentage of

riding mower–related injuries. These operators

should evaluate their ability to operate the riding

mower safely enough to protect themselves and

others from serious injury.

Slope Operation

Slopes are a major factor related to loss-of-control

and tip-over accidents, which can result in severe

injury or death. All slopes require extra caution. If

you cannot back up the slope or if you feel uneasy on

it, do not mow it.

Safety

•Mow up and down slopes, not across.

•Remove obstacles such as rocks, tree limbs, etc.

•Watch for holes, ruts or bumps. Uneven terrain

could overturn the machine. Tall grass can hide

obstacles.

•Use slow speed. Choose a low gear so that you

will not have to stop or shift while on the slope.

•Follow Toro’s recommendations for wheel

weight or counterweights to improve stability.

•Use extra care with grass catchers or other

attachments. These can change the stability of

the machine.

•Keep all movement on slopes slow and gradual.

Do not make sudden changes in speed or

direction.

•Avoid starting or stopping on a slope. If tires

lose traction, disengage the blades and proceed

slowly straight down the slope.

•Do not turn on slopes unless necessary, and then,

turn slowly and gradually downhill, if possible.

•Do not mow near drop-offs, ditches, or

embankments. The machine could suddenly turn

over if a wheel goes over the edge of a cliff or

ditch, or if an edge caves in.

•Do not mow on wet grass. Reduced traction

could cause sliding.

•Do not try to stabilize the machine by putting

your foot on the ground.

•Do not use a grass catcher on steep slopes.

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.

•Be alert and turn the machine off if children

enter the area.

•Before and while backing, look behind and down

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.

•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.

Service

•Use extra care when handling gasoline and other

fuels. They are flammable and vapors are

explosive.

A. Use only an approved container.

B. Never remove the gas cap or add fuel when

the engine is running. Allow the engine to

cool before refueling. Do not smoke.

C. Never refuel the machine indoors.

D. Never store the machine or fuel container

inside where there is an open flame, such as

near a water heater or furnace.

•Never run a machine inside a closed area.

•Keep nuts and bolts tight, especially the blade

attachment bolts. Keep equipment in good

condition.

•Never tamper with safety devices. Check their

proper operation regularly.

•Keep the machine free of grass, leaves, or other

debris build-up. Clean up oil or fuel spillage.

Allow the machine to cool before storing.

•Stop and inspect the equipment if you strike an

object. Repair, if necessary, before restarting.

Safety

•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

manufacturer’s 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.

•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 is not included in the ANSI

standard.

POTENTIAL HAZARD

•Engine exhaust contains carbon monoxide,

which is an odorless, deadly poison.

WHAT CAN HAPPEN

•Carbon monoxide can kill you and is also

known to the State of California to cause

birth defects.

HOW TO AVOID THE HAZARD

•Do not run engine indoors or in an enclosed

area.

•Stop the engine, disconnect spark plug wire(s)

and remove key before performing any service,

repairs, maintenance or adjustments.

•Slow down before turning. Sharp turns on any

terrain may cause loss of control.

•Never leave a running machine unattended.

Always turn off blades, set parking brake, stop

engine, and remove the ignition and “Key

Choice” keys before dismounting.

•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.

•Remove obstacles such as rocks, tree limbs, etc.

from the mowing area. Watch for holes, ruts or

bumps, as uneven terrain could overturn the

machine. Tall grass can hide obstacles.

•Battery acid is poisonous and can cause burns.

Avoid contact with skin, eyes and clothing.

Protect your face, eyes and clothing when

working with a battery.

•Battery gases can explode. Keep cigarettes,

sparks and flames away from battery.

•Use only genuine replacement parts to ensure

that original standards are maintained.

•Mow up and down slopes greater than 5°, not

across.

•Mow downhill only on slopes above 10°, never

mow uphill. If a steep slope must be ascended,

back up the hill, and drive forward down the hill,

keeping the machine in gear.

•Do not operate machine on hillsides or slopes

exceeding 15°.

•Avoid turning on slopes. If you must turn, turn

slowly and gradually downhill, if possible.

•Do not use a grass catcher on steep slopes.

Heavy grass bags could cause loss of control or

overturn the machine.

•Use only Toro-approved attachments. Warranty

may be voided if used with unapproved

attachments.
