Operating Safety
Congratulations on purchasing a superior-quality piece of lawn and garden equipment. Our products are designed and manufactured to meet or
exceed all industry standards for safety.
Power equipment is only as safe as the operator. If it is misused, or not
properly maintained, it can be dangerous! Remember, you are responsible for your safety and that of those around you.
Use common sense, and think through what you are doing. If you are not
sure that the task you are about to perform can be safely done with the
equipment you have chosen, ask a professional: contact your local authorized dealer.
Read the Manual
The operator’s manual contains important safety information you need to be
aware of BEFORE you operate your unit as well as DURING operation.
Safe operating techniques, an explanation of the product’s features and
controls, and maintenance information is included to help you get the
most out of your equipment investment.
Be sure to completely read the Safety Rules and Information found on
the following pages. Also completely read the Operation section.
Children
Tragic accidents can occur with children. Do not allow them
anywhere near the area of operation. Children are often attracted to the unit and mowing activity. Never assume that
children will remain where you last saw them. If there is a
risk that children may enter the area where you are mowing, have another responsible adult watch them.
DO NOT GIVE CHILDREN RIDES ON THIS UNIT! This
encourages them to come near the unit in the future while it
is running, and they could be seriously hurt. They may then
approach the unit for a ride when you are not expecting it,
and you may run over them.
Reverse
Do not mow in reverse unless absolutely necessary. Always look
down and behind before and
while traveling in reverse
even with the mower
blades disengaged.

3.5 ft
(1,5 m)
20.0 ft (6,0 m)
Slope Operation
You could be seriously injured or even killed if you use this unit on too
steep an incline. Using the unit on a slope that is too steep or where you
don’t have adequate traction can cause you to lose control or roll over.
A good rule of thumb is to not operate on any slope you cannot back up
(in 2-wheel drive mode). You should not operate on inclines with a slope
greater than a 3.5 ft (1,5 m) rise over a 20.0 ft (6,0 m) length. Always
drive up and down slopes: never cross the face.
Also note that the surface you are driving on can greatly impact stability
and control. Wet grass or icy pavement can seriously affect your ability
to control the unit.
If you feel unsure about operating the unit on an incline, don’t do it. It’s
not worth the risk.
Moving Parts
This equipment has many moving parts that can injure you or someone else. However, if you are seated in the seat properly, and follow all the rules in this book, the
unit is safe to operate.
The mower deck has spinning mower blades that can amputate hands and feet.
Do not allow anyone near the equipment while it is running!
To help you, the operator, use this equipment safely, it is equipped with an operatorpresent safety system. Do NOT attempt to alter or bypass the system. See your
dealer immediately if the system does not pass all the safety interlock system
tests found in this manual.
Thrown Objects
This unit has spinning mower blades. These blades can pick up and throw debris
that could seriously injure a bystander. Be sure to clean up the area to be
mowed BEFORE you start mowing.
Do not operate this unit without the entire grass catcher or discharge guard (deflector) in place.
Also, do not allow anyone in the area while the unit is running! If someone does
enter the area, shut the unit off immediately until they leave.
Fuel and Maintenance
Gasoline is extremely flammable. Its vapors are also extremely flammable and
can travel to distant ignition sources. Gasoline must only be used as a fuel, not
as a solvent or cleaner. It should never be stored any place where its vapors
can build up or travel to an ignition source like a pilot light. Fuel belongs in an
approved, plastic, sealed gas can, or in the tractor fuel tank with the cap securely closed. Spilled fuel needs to be cleaned up immediately.
Proper maintenance is critical to the safety and performance of your unit. Be
sure to perform the maintenance procedures listed in this manual, especially periodically testing the safety system.

GENERAL OPERATION
1. Read, understand, and follow all instructions in the
manual and on the unit before starting.
2. Do not put hands or feet near rotating parts or under
the machine. Keep clear of the discharge opening at all
times.
3. Only allow responsible adults, who are familiar with the
instructions, to operate the unit (local regulations can
restrict operator age).
4. Clear the area of objects such as rocks, toys, wire, etc.,
which could be picked up and thrown by the blade(s).
5. Be sure the area is clear of other people before mowing. Stop the unit if anyone enters the area.
6. Never carry passengers.
7. Do not mow in reverse unless absolutely necessary. Always look down and behind before and while travelling
in reverse.
8. Never direct discharge material toward anyone. Avoid
discharging material against a wall or obstruction. Material may ricochet back toward the operator. Stop the
blade(s) when crossing gravel surfaces.
9. Do not operate the machine without the entire grass
catcher, discharge guard (deflector), or other safety devices in place.
10. Slow down before turning.
11. Never leave a running unit unattended. Always disengage the PTO, set parking brake, stop engine, and remove keys before dismounting.
12. Disengage blades (PTO) when not mowing. Shut off
engine and wait for all parts to come to a complete stop
before cleaning the machine, removing the grass
catcher, or unclogging the discharge guard.
13. Operate the machine only in daylight or good artificial
light.
14. Do not operate the unit while under the influence of alcohol or drugs.
15 Watch for traffic when operating near or crossing road-
ways.
16. Use extra care when loading or unloading the unit into a
trailer or truck.
17. Always wear eye protection when operating this unit.
18. Data indicates that operators, age 60 years and above,
are involved in a large percentage of power equipmentrelated injuries. These operators should evaluate their
ability to operate the equipment safely enough to protect themselves and others from injury.
19. Follow the manufacturer’s recommendations for wheel
weights or counterweights.
20. Keep in mind the operator is responsible for accidents
occurring to other people or property.
21. All drivers should seek and obtain professional and
practical instruction.
22. Always wear substantial footwear and trousers. Never
operate when barefoot or wearing sandals.
23. Before using, always visually check that the blades and
blade hardware are present, intact, and secure. Replace worn or damaged parts.
24. Disengage attachments before: refueling, removing an
attachment, making adjustments (unless the adjustment
can be made from the operator’s position).
25. When the machine is parked, stored, or left unattended,
lower the cutting means unless a positive mechanical
lock is used.
26. Before leaving the operator’s position for any reason,
engage the parking brake (if equipped), disengage the
PTO, stop the engine, and remove the key.
27. To reduce fire hazard, keep the unit free of grass,
leaves, & excess oil. Do not stop or park over dry
leaves, grass, or combustible materials.
28. It is a violation of California Public Resource Code Section 4442 to use or operate the engine on or near any
forest-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark arrester meeting any applicable local or state laws. Other
states or federal areas may have similar laws.
Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit,
severe personal injury or death to you, or bystanders, or damage to property or equipment. This mowing deck
is capable of amputating hands and feet and throwing objects. The triangle in text signifies important cautions or warnings which must be followed.
TRANSPORTING AND STORAGE
1. When transporting the unit on an open trailer, make
sure it is facing forward, in the direction of travel. If the
unit is facing backwards, wind lift could damage the unit.
2. Always observe safe refueling and fuel handling practices when refueling the unit after transportation or storage.
3. Never store the unit (with fuel) in an enclosed poorly
ventilated structure. Fuel vapors can travel to an ignition source (such as a furnace, water heater, etc.) and
cause an explosion. Fuel vapor is also toxic to humans
and animals.
4. Always follow the engine manual instructions for storage preparations before storing the unit for both short
and long term periods.
5. Always follow the engine manual instructions for proper
start-up procedures when returning the unit to service.
6. Never store the unit or fuel container inside where

CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the unit
and the mowing activity. Never assume that children will remain where you last saw them.
1. Keep children out of the mowing area and under the
watchful care of another responsible adult.
2. Be alert and turn unit off if children enter the area.
3. Before and during reverse operation, look behind and
down for small children.
4. Never carry children, even with the blade(s) off. They
may fall off and be seriously injured or interfere with
safe unit operation. Children who have been given
rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over by
the machine.
5. Never allow children to operate the unit.
6. Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure vision.
EMISSIONS
1. Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth defects, or other reproductive harm.
2. Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
IGNITION SYSTEM
1. This spark ignition system complies with Canadian
ICES-002.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not operate
on it.
Control of a walk-behind or ride-on machine sliding on a
slope will not be regained by the application of the brake.
The main reasons for loss of control are: insufficient tire grip
on the ground, speed too fast, inadequate braking, the type
of machine is unsuitable for its task, lack of awareness of the
ground conditions, incorrect hitching and load distribution.
1. Mow up and down slopes, not across.
2. Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.
3. Choose a slow speed so that you will not have to stop
or change speeds while on the slope.
4. Do not mow on wet grass. Tires may loose traction.
5. Always keep unit in gear especially when traveling
down slopes. Do not shift to neutral and coast downhill.
6. Avoid starting, stopping, or turning on a slope. If tires
lose traction, disengage the blade(s) and proceed
slowly straight down the slope.
7. Keep all movement on slopes slow and gradual. Do not
make sudden changes in speed or direction, which
could cause the machine to rollover.
8. Use extra care while operating machines with grass
catchers or other attachments; they can affect the stability of the unit. Do not use on steep slopes.
9. Do not try to stabilize the machine by putting your foot
on the ground (ride-on units).
10. Do not mow near drop-offs, ditches, or embankments.
The mower could suddenly turn over if a wheel is over
the edge of a cliff or ditch, or if an edge caves in.
11. Do not use grass catchers on steep slopes.
12. Do not mow slopes you cannot back up them.
13. See your authorized dealer/retailer for recommendations of wheel weights or counterweights to improve
stability.
14. Remove obstacles such as rocks, tree limbs, etc.
15. Use slow speed. Tires may lose traction on slopes even
through the brakes are functioning properly.
16. Do not turn on slopes unless necessary, and then, turn
slowly and gradually downhill, if possible.
TOWED EQUIPMENT (RIDE-ON UNITS)
1. Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.
2. Follow the manufacturer’s recommendations for weight
limit for towed equipment and towing on slopes.
3. Never allow children or others in or on towed equipment.
4. On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Do not shift to neutral and coast down hill.
WARNING
Never operate on slopes greater than 17.6 percent
(10°) which is a rise of 3-1/2 feet (106 cm) vertically in
20 feet (607 cm) horizontally.
When operating on slopes use additional wheel weights
or counterweights. See your dealer/retailer to
determine which weights are available and appropriate
for your unit.
Select slow ground speed before driving onto slope. In
addition to front weights, use extra caution when
operating on slopes with rear-mounted grass catchers.
Mow UP and DOWN the slope, never across the face,
use caution when changing directions and DO NOT
START OR STOP ON SLOPE.

Storage
WARNING
Never store the unit (with fuel) in an enclosed,
poorly ventilated structure. Fuel vapors can travel to
an ignition source (such as a furnace, water
heater, etc.) and cause an explosion. Fuel
vapor is also toxic to humans and animals.
When Storing Fuel Or Equipment With Fuel In Tank
• Store away from furnaces, stoves, water heaters or
other appliances that have pilot lights or other ignition
sources because they can ignite fuel vapors.
Equipment
Disengage the PTO, set the parking brake, and remove
the key.
Battery life will be increased if it is removed. Put in a cool,
dry place and fully charged about once a month. If the
battery is left in the unit, disconnect the negative cable.
Fuel System
Fuel can become stale when stored over 30 days. Stale
fuel causes acid and gum deposits to form in the fuel system or on essential carburetor parts. To keep fuel fresh,
use Briggs & Stratton FRESH START® fuel stabilizer,
available as a liquid additive or a drip concentrate cartridge.
There is no need to drain gasoline from the engine if a
fuel stabilizer is added according to instructions. Run the
engine for 2 minutes to circulate the stabilizer throughout
the fuel system. The engine and fuel can then be stored
up to 24 months.
If gasoline in the engine has not been treated with a fuel
stabilizer, it must be drained into an approved container.
Run the engine until it stops from lack of fuel. The use of a
fuel stabilizer in the storage container is recommended to
maintain freshness.
www.simplicitymfg.com
Engine Oil
While the engine is still warm, change the engine oil. See
Engine Manual.
Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance items.
• Perform all recommended checks and procedures
found in this manual.
• Allow the engine to warm up for several minutes before use.

LOOK FOR RELEVANT EMISSIONS DURABILITY PERIOD AND AIR INDEX INFORMATION ON YOUR ENGINE
EMISSIONS LABEL
Engines that are certified to meet the California Air Resources Board (CARB)
Emissions Standard must display information regarding the Emissions Durability
Period and the Air Index. Briggs & Stratton makes this information available to
the consumer on our emissions labels. The engine emissions label will indicate
certification information.
The Emissions Durability Period describes the number of hours of actual
running time for which the engine is certified to be emissions compliant, assuming
proper maintenance in accordance with the Operating & Maintenance Instructions.
The following categories are used:
Moderate:
Engine is cer
for 125 hours of actual engine running time.
Intermediate:
Engine is certified to be emissions compliant
for 250 hours of actual engine running time.
Extended:
Engine is certified to be emissions compliant
for 500 hours of actual engine running time.
tified to be emissions compliant
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year.
Therefore, the Emissions Durability Period of an engine with an intermediate
rating would equate to 10 to 12 years.
Briggs & Stratton engines are certified to meet the United States Environmental
Protection Agency (USEPA) Phase 2 emissions standards. For Phase 2 certified
engines, the Emissions Compliance Period referred to on the Emissions
Compliance label indicates the number of operating hours for which the engine
has been shown to meet Federal emissions requirements.
For engines less than 225 cc displacement:
Category C = 125 hours
Category B = 250 hours
Category A = 500 hours
For engines of 225 cc or more displacement:
Category C = 250 hours
Category B = 500 hours
Category A = 1000 hours

*The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are
derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating
conditions and engine-to-engine variability. Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power
when used in a given piece of power equipment (actual "on-site" or net horsepower). This difference is due to a variety of
factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to
manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.
