avoid serious injury or death.
This product is designed for cutting and recycling grass or,
when equipped with a grass bagger, for catching cut grass.
Any use for purposes other than these could prove
dangerous to user and bystanders.
Safe Operating Practices
The following instructions are from ANSI standard
B71.4—1999.
Training
• Read the Operator’s Manual and other training material.
If the operator(s) or mechanic(s) can not read English it
is the owner’s responsibility to explain this material to
them.
• Become familiar with the safe operation of the
equipment, operator controls, and safety signs.
• All operators and mechanics should be trained. The
owner is responsible for training the users.
• Never let children or untrained people operate or
service the equipment. Local regulations may restrict
the age of the operator.
• The owner/user can prevent and is responsible for
accidents or injuries occurring to himself or herself,
other people or property.
Danger signals an extreme hazard that will cause serious
injury or death if you do not follow the recommended
precautions.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
This manual uses two other words to highlight information.
Important calls attention to special mechanical
information and Note: emphasizes general information
worthy of special attention.
Preparation
• Evaluate the terrain to determine what accessories and
attachments are needed to properly and safely perform
the job. Only use accessories and attachments approved
by the manufacturer.
• Wear appropriate clothing including hard hat, safety
glasses and hearing protection. Long hair, loose
clothing or jewelry may get tangled in moving parts.
• Inspect the area where the equipment is to be used and
remove all objects such as rocks, toys and wire which
can be thrown by the machine.
3
• Use extra care when handling gasoline and other fuels.
They are flammable and vapors are explosive.
• Use only an approved container
• Never remove gas cap or add fuel with engine
running. Allow engine to cool before refueling.
Do not smoke.
• Never refuel or drain the machine indoors.
• Check that operator’s presence controls, safety switches
and shields are attached and functioning properly. Do
not operate unless they are functioning properly.
• Use care when approaching blind corners, shrubs, trees,
or other objects that may obscure vision.
Slope Operation
• Do not mow slopes greater than 15 degrees.
• Do not mow near drop–offs, ditches, steep banks or
water. Wheels dropping over edges can cause rollovers,
which may result in serious injury, death or drowning.
• Do not mow slopes when grass is wet. Slippery
conditions reduce traction and could cause sliding and
loss of control.
Operation
• Never run an engine in an enclosed area.
• Only operate in good light, keeping away from holes
and hidden hazards.
• Be sure all drives are in neutral and parking brake is
engaged before starting engine. Start the engine only
from the operator’s position.
• Never raise deck with the blades running.
• Never operate without the PTO shield, or other guards
securely in place. Be sure all interlocks are functioning
properly.
• Never operate with the discharge deflector raised,
removed or altered, unless using a grass catcher.
• Do not change the engine governor setting or overspeed
the engine.
• Stop on level ground, lower implements, disengage
drives, engage parking brake, shut off engine before
leaving the operator’s position for any reason including
emptying the catchers or unclogging the chute.
• Stop equipment and inspect blades after striking objects
or if an abnormal vibration occurs. Make necessary
repairs before resuming operations.
• Keep hands and feet away from the cutting units.
• Never carry passengers and keep pets and bystanders
away.
• Be alert, slow down and use caution when making
turns. Look behind and to the side before changing
directions.
• Slow down and use caution when crossing roads and
sidewalks. Stop blades if not mowing.
• Be aware of the mower discharge direction and do not
point it at anyone.
• Do not operate the mower under the influence of
alcohol or drugs.
• Use extreme care when loading or unloading the
machine into a trailer or truck.
• Do not make sudden turns or rapid speed changes.
• Use a walk behind mower and/or a hand trimmer near
drop–offs, ditches, steep banks or water.
• Reduce speed and use extreme caution on slopes.
• Remove or mark obstacles such as rocks, tree limbs,
etc. from the mowing area. Tall grass can hide
obstacles.
• Watch for ditches, holes, rocks, dips, and rises that
change the operating angle, as rough terrain could
overturn the machine.
• 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 slip and cause loss of braking and
steering.
• Always avoid sudden starting or stopping on a slope. If
tires lose traction, disengage the blades and proceed
slowly off the slope.
• Follow the manufacturer’s recommendations for wheel
weights or counterweights to improve stability.
• Use extreme care with grass catchers or other
attachments. These can change the stability of the
machine and cause loss of control.
Using the Rollover Protection System
(ROPS)
• Keep the roll bar in the raised and locked position and
use the seat belt when operating the machine.
• Be certain that the seat belt can be released quickly in
the event of an emergency.
• Be aware there is no rollover protection when the roll
bar is down.
• Check the area to be mowed and never fold the ROPS
in areas where there are slopes, drop offs or water.
4
• Lower the rollbar only when absolutely necessary. Do
not wear the seat belt with the roll bar folded down.
• Check carefully for overhead clearances (i.e. branches,
doorways, electrical wires) before driving under any
objects and do not contact them.
Maintenance and storage
• Disengage drives, lower implement, set parking brake,
stop engine and remove key or disconnect spark plug
wire. Wait for all movement to stop before adjusting,
cleaning or repairing.
• Clean grass and debris from cutting units, drives,
mufflers, and engine to help prevent fires. Clean up oil
or fuel spillage.
• Let engine cool before storing and do not store near
flame.
• Shut off fuel while storing or transporting. Do not store
fuel near flames or drain indoors.
• Park machine on level ground. Never allow untrained
personnel to service machine.
• Use jack stands to support components when required.
• Carefully release pressure from components with stored
energy.
• Disconnect battery or remove spark plug wire before
making any repairs. Disconnect the negative terminal
first and the positive last. Reconnect positive first and
negative last.
• Use care when checking blades. Wrap the blade(s) or
wear gloves, and use caution when servicing them.
Only replace blades. Never straighten or weld them.
• Keep hands and feet away from moving parts. If
possible, do not make adjustments with the engine
running.
• Charge batteries in an open well ventilated area, away
from spark and flames. Unplug charger before
connecting or disconnecting from battery. Wear
protective clothing and use insulated tools.
• Keep all parts in good working condition and all
hardware tightened. Replace all worn or damaged
decals.
• Use only Toro-approved attachments. Warranty may be
voided if used with unapproved attachments.

Gasoline and Oil
Recommended Gasoline
Use UNLEADED Regular Gasoline suitable for automotive
use (85 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% ethanol
because the fuel system could be damaged. Do not mix oil
with gasoline.
Danger
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 level is 1/4 to
1/2 inch (6 to 13 mm) below the bottom 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.
• 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.
• 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.
• Do not operate without entire exhaust system in
place and in proper working condition.
Warning
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.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
• Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
• Cleans the engine while it runs
• Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting
Important Do not use fuel additives containing
methanol or ethanol.
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.
Filling the Fuel Tank
1. Shut the engine off and set the parking brake.
2. Clean around each fuel tank cap and remove the cap.
Add unleaded regular gasoline to both fuel tanks, until
the level is 1/4 to 1/2 inch (6 to 13 mm) below the
bottom of the filler neck. This space in the tank allows
gasoline to expand. Do not fill the fuel tanks completely
full.
3. Install fuel tank caps securely. Wipe up any gasoline
that may have spilled.
Checking the Engine Oil Level
Before you start the engine and use the machine, check the
oil level in the engine crankcase; refer to Checking the
Engine Oil Level, page 29.
