switches, and guards are attached and working
properly. Do not operate the machine unless they
are functioning properly.
• Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operator’s position. Allow the machine to cool
before servicing, adjusting, fueling, cleaning, or
storing it.
• Before mowing, inspect the machine to ensure
that the cutting assemblies are working properly.
• Evaluate the terrain to determine the appropriate
equipment and any attachments or accessories
required to operate the machine properly and
safely.
• Wear appropriate clothing, including eye
protection; long pants; substantial, slip-resistant
footwear; and hearing protection. Tie back long
hair and do not wear loose clothing or loose
jewelry.
• Do not carry passengers on the machine.
• Keep bystanders and pets away from the machine
during operation. Shut off the machine and
attachment(s) if anyone enters the area.
• Do not operate the machine unless all guards and
safety devices, such as the deectors and the
entire grass catcher, are in place and functioning
properly. Replace worn or deteriorated parts when
necessary.
Fuel Safety
• Fuel is extremely ammable and highly explosive.
A re or explosion from fuel can burn you and
others and can damage property.
– To prevent a static charge from igniting the
fuel, remove the machine from the truck or
trailer and refuel it on the ground, away from
all vehicles. If this is not possible, place a
portable fuel container on the ground, away
from all vehicles, and ll it; then refuel the
machine from the fuel container rather than
from a fuel-dispenser nozzle.
– 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 ame 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.
• 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.
• Do not store the machine or fuel container where
there is an open ame, 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.
• 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.
• If you spill fuel on your clothing, change your
clothing immediately.
• Do not overll the fuel tank. Replace the fuel cap
and tighten it securely.
• Clean grass and debris from the cutting unit,
mufer, drives, grass catcher, and engine
compartment to help prevent res. Clean up oil or
fuel spills.

During Operation
During Operation Safety
General 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 inuence of alcohol or drugs.
• Contacting the blade can result in serious personal
injury. Shut off the engine, remove the key, and
wait for all moving parts to stop before leaving the
operating position. When you turn the key to the
OFF position, the engine should shut off and the
blade should stop. If not, stop using your machine
immediately and contact an Authorized Service
Dealer.
• Operate the machine only in good visibility and
appropriate weather conditions. Do not operate
the machine when there is the risk of lightning.
• Keep your hands and feet away from the cutting
units. Keep clear of the discharge opening.
• Do not mow in reverse unless it is absolutely
necessary. Always look down and behind you
before moving the machine in reverse.
• Use extreme care when approaching blind
corners, shrubs, trees, or other objects that may
block your view.
• Stop the blades whenever you are not mowing.
• If the machine strikes an object or starts to vibrate,
immediately shut off the engine, remove the key
(if equipped), 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.
• 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.
• Operate the engine only in well-ventilated areas.
Exhaust gases contain carbon monoxide, which
is lethal if inhaled.
• Never leave a running machine unattended.
• Attach towed equipment to the machine only at
the hitch point.
• Do not operate the machine unless all guards
and safety devices, such as the deectors, are in
place and functioning properly. Replace worn or
deteriorated parts when necessary.
• Use only accessories and attachments approved
by Toro.
• This machine produces sound levels in excess
of 85 dBA at the operator’s ear and can cause
hearing loss through extended periods of
exposure.
g229846
Figure 12
1. Wear hearing protection.
• Clean grass and debris from the cutting unit,
drives, mufer, and engine to help prevent res.
• Start the engine with your feet well away from the
blades.
18
• 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.
• Stop the blades, slow down the machine, and use
caution when crossing surfaces other than grass
or when transporting the machine to and from the
operating area.
• Do not change the engine governor speed or
overspeed the engine.
• 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 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.
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.
– 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.
• 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.

Rollover Protection System
(ROPS) Safety
• The ROPS is an integral safety device. Do not
remove any of the ROPS components from the
machine.
• Ensure that the seat belt is attached and that you
can release it quickly in an emergency.
• Keep the roll bar in the fully raised and locked
position and always wear your seat belt whenever
the roll bar is up.
• Check carefully for overhead objects before you
drive under them, and do not contact them.
• Replace damaged ROPS components. Do not
repair or alter them.
• There is no rollover protection when the roll bar
is down.
• Wheels dropping over edges, over steep banks, or
into water can cause a rollover, which may result
in serious injury or death.
• Do not wear the seat belt when the roll bar is down.
• Lower the roll bar only when absolutely necessary;
raise it as soon as clearance permits.
• In the event of a rollover, take the machine to an
Authorized Service Dealer to inspect the ROPS.
• Use only Toro approved accessories and
attachments for the ROPS.

Driving the Machine
The drive wheels turn independently, powered by
hydraulic 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.
The throttle control regulates the engine speed as
measured in rpm (revolutions per minute). Place
the throttle control in the FAST position for best
performance. Always operate in the full throttle
position when mowing.
WARNING
The machine can spin very rapidly. You
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.
Driving Forward
Note: The engine shuts off when you move the
traction-control with the parking brake engaged.
To stop the machine, pull the motion-control levers
to the NEUTRAL position.
1. Disengage the parking brake.
2. Move the motion-control levers to the center,
unlocked position.

Using the Side Discharge
The mower has a hinged grass deector that
disperses clippings to the side and down toward the
turf.
DANGER
Without a grass deector, discharge cover, or
a 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 deector from the
mower deck because the grass deector
routes material down toward the turf. If the
grass deector is ever damaged, replace it
immediately.
• Never put your hands or feet under the
mower deck.
• Never try to clear the discharge area
or mower blades unless you move the
blade-control switch (PTO) to the OFF
position, rotate the key switch to the OFF
position, and remove the key from the key
switch.
• Make sure that the grass deector is in the
down position.
Adjusting the Height of Cut
Using the Transport Lock
The transport lock has 2 positions, and is used with
the deck-lift pedal. There is a LOCK position and

Operating Tips
Maximizing Air Circulation
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
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.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure that
the cutting height of the mower deck 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 15 cm (6 inches) tall,
you may want to cut the lawn twice to ensure an
acceptable quality of cut.
Cutting 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.
Alternating the Mowing Direction
Alternate the mowing direction to keep the grass
standing straight. This also helps disperse clippings,
which enhances decomposition and fertilization.
Mowing at Correct Intervals
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, rst mow at a
high cutting height, then mow again 2 days later at a
lower height setting.
Mowing at Slower Speeds
In certain conditions, mowing at a slower ground
speed can improve cut quality.
Avoiding Cutting Too Low
When mowing uneven turf, raise the cutting height
to avoid scalping the turf.
Stopping the Machine
If you must stop the forward motion of the machine
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.
Keeping the Underside of the
Mower Deck Clean
Clean clippings and dirt from the underside of the
mower deck after each use. If grass and dirt build up
inside the mower deck, cutting quality will eventually
become unsatisfactory.
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. Refer to
Servicing
the Cutting Blades (page 52)
.

or truck has all the necessary brakes, lighting, and
marking as required by law. Please carefully read all
the safety instructions. Knowing this information could
help you or bystanders avoid injury. Refer to your
local ordinances for trailer and tie-down requirements.
WARNING
Driving on the street or roadway without
turn signals, lights, reective markings, or a
slow-moving-vehicle emblem is dangerous
and can lead to accidents, causing personal
injury.
Do not drive the machine on a public street
or roadway.
Selecting a Trailer
WARNING

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 claried 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 signicant 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 signicant 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.
