Operation
Page 41
3465-582 A
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 fueldispenser 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.

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.
· 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.
Operation: During Operation
Page 47
3465-582 A
During Operation Safety (continued)
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.
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.
Towing Safety
· Do not attach towed equipment except at the hitch point. · Do not use the
machine as a towing vehicle unless it has a hitch installed. · Do not exceed
the maximum gross towing weight. · Never allow children or others near the
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. · The
stopping distance may increase with the weight of a towed load. Travel slowly
and
allow extra distance to stop. · Make wide turns to keep the attachment clear
of the machine.

G454155
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.
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.
3465-582A
Page 416
Operation: During Operation
Operating Tips (continued)
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.
After Operation
After Operation Safety
· Park the machine on a level surface, disengage the drives, engage the
parking brake, shut off the engine, remove the key, and wait for all moving
parts to stop before leaving the operator’s position.
· Wait for the machine to cool before servicing, adjusting, fueling, cleaning,
or storing it. · Clean grass, leaves, excessive grease and oil, and other
debris from the mower deck,
