machine immediately and contact an Authorized Service Dealer.
• Before mowing, inspect the machine to ensure that the cutting assemblies are working
properly.
• Keep bystanders, particularly children, and pets away from the machine during
operation. Shut off the machine and attachment(s) if anyone enters the area.
3464-621 A Page 4–1 Operation
Before Operation Safety (continued)
Fuel Safety
• Fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn
you and others and can damage property.
– To prevent a static charge from igniting the fuel, place the container and/or machine
directly on the ground before filling, not in a vehicle or on an object.
– Fill the fuel tank outdoors on level ground, in an open area, and when the engine is
cold. Wipe up any fuel that spills.
– Do not handle fuel when smoking or around an open flame or sparks.
– Do not remove the fuel cap or add fuel to the tank while the engine is running or hot.
– If you spill fuel, do not attempt to start the engine. Avoid creating a source of ignition
until the fuel vapors have dissipated.
– Store fuel in an approved container and keep it out of the reach of children.
• Do not overfill the fuel tank. Replace the fuel cap and tighten it securely.
• In certain conditions during fueling, static electricity can be released, causing a spark that
can ignite fuel vapors.
• Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner.
Always place containers on the ground and away from your vehicle before filling.
• Remove the equipment from the truck or trailer and refuel it while it is on the ground. If
this is not possible, then refuel from a portable container rather than from a fuel-
dispenser nozzle.
• Keep the fuel-dispenser nozzle in contact with the rim of the fuel tank or container
opening at all times until fueling is complete. Do not use a nozzle lock-open device.
• Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious
injury and illness.
– Avoid prolonged breathing of vapors.
– Keep your hands and face away from the nozzle and the fuel-tank opening.
– Keep fuel away from your eyes and skin.
• Clean up any spilled fuel.
• Do not store the machine or fuel container where there is an open flame, spark, or pilot
light, such as on a water heater or on other appliances.
• Do not operate the machine without the entire exhaust system in place and in proper
working condition.

Performing Daily Maintenance
Before starting the machine each day, perform the Each Use/Daily procedures listed in the
Maintenance Schedule.
3464-621A Page 4–3 Operation: Before Operation
Break-In Time
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.
Safety-Interlock System
The safety-interlock system is designed to prevent the engine from starting unless:
• The blade-control switch (PTO) is disengaged.
• The motion-control levers are in the P
ARK position.
The safety-interlock system also is designed to shut off the engine whenever the control
levers are out of the P
ARK position and you rise from the seat.
WARNING
If the 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.
Testing the Safety-Interlock System
Test the safety-interlock system before you use the machine each time. If the safety system
does not operate as described below, have an Authorized Service Dealer repair the safety
system immediately.

During Operation
During Operation Safety
• The owner/operator can prevent and is responsible for accidents that may cause
personal injury or property damage.
• Use your full attention while operating the machine. Do not engage in any activity that
causes distractions; otherwise, injury or property damage may occur.
• Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.
• Do not operate the machine unless all guards and safety devices, such as the deflectors
and the entire grass catcher, are in place and functioning properly. Replace worn or
deteriorated parts with genuine Toro parts when necessary.
• Operating engine parts, especially the muffler, can become extremely hot. Severe burns
can occur on contact and debris, such as leaves, grass, brush, etc. can catch fire. Keep
the engine area free from debris and excessive oil and grease.
• Operate the engine only in well-ventilated areas. Exhaust gases contain carbon
monoxide, which is lethal if inhaled.
• Operate the machine only in good visibility and appropriate weather conditions. Do not
operate the machine when there is the risk of lightning.
• Start the engine with your feet well away from the blades.
• Keep your hands and feet away from moving parts. Keep clear of the discharge opening.
• Keep away from holes, ruts, bumps, rocks, and other hazards. Use care when
approaching blind corners, shrubs, trees, tall grass or other objects that may hide
obstacles or obscure your view.
• Do not mow with the discharge deflector raised, removed, or altered unless there is a
grass-collection system or mulch kit in place and working properly.
3464-621A Page 4–7 Operation: Before Operation
During Operation Safety (continued)
• Do not mow in reverse unless it is absolutely necessary. Always look down and behind
you before moving the machine in reverse.
• Stop the blades whenever you are not mowing. Slow down the machine, and use caution
when crossing surfaces other than grass or when transporting the machine to and from
the operating area.
• Be aware of the mower discharge path and direct the discharge away from others. Avoid
discharging material against a wall or obstruction because the material may ricochet
back toward you.
• If the machine strikes an object or starts to vibrate, immediately shut off the engine,
remove the key, and wait for all moving parts to stop before examining the machine for
damage. Make all necessary repairs before resuming operation.
• Slow down and use caution when making turns and crossing roads and sidewalks with
the machine. Always yield the right-of-way.
• Never leave a running machine unattended.
• Before you leave the operating position, do the following:
– Park the machine on a level surface.
– Disengage the power takeoff and lower the attachments.
– Engage the parking brake.
– Shut off the engine and remove the key.
– Wait for all moving parts to stop.
• Never carry children on the machine.
• Do not carry children on the machine, even when the blades are not moving. Children
could fall off and be seriously injured or prevent you from safely operating the machine.
Children who have been given rides in the past could appear in the operating area
without warning and be run over or backed over by the machine.
• 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 operating area and under the watchful care of a responsible
adult other than the operator.
• Be alert and shut off the machine if children enter the operating area.
• Before backing up or turning the machine, look down and all around for small children.
• Do not use the machine as a towing vehicle unless it has a hitch installed. Attach towed
equipment to the machine only at the hitch point.
• Use only accessories and attachments approved by The Toro® Company.
Slope Safety
• Slopes are a major factor related to loss of control and rollover accidents, which can
result in severe injury or death. The operator is responsible for safe slope operation.
Operating the machine on any slope requires extra caution. Before using the machine on
a slope, do the following:
– Review and understand the slope instructions in the manual and on the machine.
Operation: During Operation Page 4–8 3464-621 A
During Operation Safety (continued)
– Use an angle indicator to determine the approximate slope angle of the area.
– Never operate on slopes greater than 15°.
– Evaluate the site conditions of the day to determine if the slope is safe for machine
operation. Use common sense and good judgment when performing this evaluation.
Changes in the terrain, such as moisture, can quickly affect the operation of the
machine on a slope.
• Identify hazards at the base of the slope. Do not operate the machine near drop-offs,
ditches, embankments, water, or other hazards. The machine could suddenly roll over if
a wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width
of the machine) between the machine and any hazard. Use a walk-behind machine or a
hand trimmer to mow the grass in these areas.
G229111s
Safe Zone—use the machine

W = Width of the machine
Keep a safe distance (twice the
width of the machine) between the
machine and any hazard.
• Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden
changes in speed or direction; turn slowly and gradually.
• Do not operate a machine under any conditions where traction, steering, or stability is in
question. Be aware that operating the machine on wet grass, across slopes, or downhill
may cause the machine to lose traction. Loss of traction to the drive wheels may result in
sliding and a loss of braking and steering. The machine can slide even if the drive wheels
are stopped.
• Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks, or other hidden
hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.
• Use extra care while operating with accessories or attachments, such as grass-collection
systems. These can change the stability of the machine and cause a loss of control.
Follow directions for counterweights.
• If possible, keep the deck lowered to the ground while operating on slopes. Raising the
deck while operating on slopes can cause the machine to become unstable.

Driving the Machine
CAUTION
Positioning one lever too far in front of the other causes the machine to spin very
rapidly. As a result, you may lose control of the machine, causing personal injury to
you and damage to the machine.
Slow down the machine before making sharp turns.
The drive wheels turn independently, powered by motors on each axle. You can turn 1 side
in reverse while you turn the other forward, causing the machine to spin rather than turn.
This greatly improves the machine maneuverability but may require some time for you to
adapt to how it moves.

DANGER
Without the grass deflector, discharge cover, or complete grass catcher assembly
mounted in place, you and bystanders are exposed to blade contact and thrown
debris. Contact with rotating mower blade(s) and thrown debris will cause injury or
death.
• Do not remove the grass deflector from the machine, because the grass deflector
routes material down toward the turf. If the grass deflector is ever damaged,
replace it immediately.
• Never try to clear the discharge area or mower blades unless the power takeoff
(PTO) is off. Rotate the key to the O
FF position and remove the key.

flat mowing areas.
G454259
Operating Tips
Maximize Air Circulation
For best mowing and maximum air circulation, operate the engine at the FAST position. Air
circulation is required to thoroughly cut grass clippings, so do not set the height-of-cut so low
as to totally surround the mower deck in uncut grass. Always try to have 1 side of the mower
deck free from uncut grass, which allows air to be drawn into the mower deck.
3464-621A Page 4–15 Operation: During Operation
Operating Tips (continued)
Avoid Cutting Too Low
When mowing uneven ground, raise the cutting height to slightly higher than normal to avoid
scalping the turf. However, the cutting height used in the past is generally the best one 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 a third 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.
Alternate the Mowing Direction
Alternate the mowing direction to keep the grass standing straight. This also helps disperse
clippings, which enhances decomposition and fertilization.
Mowing Frequency
Grass grows at different rates at different times of the year. To maintain the same cutting
height, 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.
Mow at Slower Ground Speeds
In certain conditions, mowing at a slower ground speed can improve cut quality.
Avoid Grass Clumps
If you must stop driving forward 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
disengage the mower deck while moving forward.
Keep the Underside of the Mower Deck Clean
Clean clippings and dirt from the underside of the mower deck after each use. Grass and dirt
build-up will eventually decrease the cutting quality.
Maintain the Blades
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.

California Proposition 65 Warning Information
What is this warning?
You may see a product for sale that has a warning label like the following:
WARNING: Cancer and Reproductive Harm—www.p65Warnings.ca.gov.
What is Prop 65?
Prop 65 applies to any company operating in California, selling products in California, or manufacturing products that may
be sold in or brought into California. It mandates that the Governor of California maintain and publish a list of chemicals
known to cause cancer, birth defects, and/or other reproductive harm. The list, which is updated annually, includes
hundreds of chemicals found in many everyday items. The purpose of Prop 65 is to inform the public about exposure to
these chemicals.
Prop 65 does not ban the sale of products containing these chemicals but instead requires warnings on any product,
product packaging, or literature with the product. Moreover, a Prop 65 warning does not mean that a product is in violation
of any product safety standards or requirements. In fact, the California government has clarified that a Prop 65 warning “is
not the same as a regulatory decision that a product is ‘safe’ or ‘unsafe.’” Many of these chemicals have been used in
everyday products for years without documented harm. For more information, go to https://oag.ca.gov/prop65/faqs-view-all.
A Prop 65 warning means that a company has either (1) evaluated the exposure and has concluded that it exceeds the “no
significant risk level”; or (2) has chosen to provide a warning based on its understanding about the presence of a listed
chemical without attempting to evaluate the exposure.
Does this law apply everywhere?
Prop 65 warnings are required under California law only. These warnings are seen throughout California in a wide range of
settings, including but not limited to restaurants, grocery stores, hotels, schools, and hospitals, and on a wide variety of
products. Additionally, some online and mail order retailers provide Prop 65 warnings on their websites or in catalogs.
How do the California warnings compare to federal limits?
Prop 65 standards are often more stringent than federal and international standards. There are various substances that
require a Prop 65 warning at levels that are far lower than federal action limits. For example, the Prop 65 standard for
warnings for lead is 0.5 μg/day, which is well below the federal and international standards.
Why don’t all similar products carry the warning?
• Products sold in California require Prop 65 labelling while similar products sold elsewhere do not.
• A company involved in a Prop 65 lawsuit reaching a settlement may be required to use Prop 65 warnings for its
products, but other companies making similar products may have no such requirement.
• The enforcement of Prop 65 is inconsistent.
• Companies may elect not to provide warnings because they conclude that they are not required to do so under Prop 65;
a lack of warnings for a product does not mean that the product is free of listed chemicals at similar levels.
Why does Toro include this warning?
Toro has chosen to provide consumers with as much information as possible so that they can make informed decisions
about the products they buy and use. Toro provides warnings in certain cases based on its knowledge of the presence of
one or more listed chemicals without evaluating the level of exposure, as not all the listed chemicals provide exposure limit
requirements. While the exposure from Toro products may be negligible or well within the “no significant risk” range, out of
an abundance of caution, Toro has elected to provide the Prop 65 warnings. Moreover, if Toro does not provide these
warnings, it could be sued by the State of California or by private parties seeking to enforce Prop 65 and subject to
substantial penalties.
