Safe Operation Practices
Operating 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.
en
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.

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 foot rise over a 20 foot length. Always drive up and down slopes:
never cross the face.
3.5 ft
(1,5 m)
20.0 ft (6,0 m)
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.
Do not allow anyone in the mowing 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. Fuel 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 and be
sure to periodically test the safety system.

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 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 lose 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 if 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.
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.
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.

heater or other appliance.
6. Never fill containers inside a vehicle or on a truck bed
with a plastic bed liner. Always place containers on the
ground away from your vehicle before filling.
7. Remove gas-powered equipment from the truck or
trailer and refuel it on the ground. If this is not possible,
then refuel such equipment on a trailer with a portable
container, rather than from a gasoline dispenser nozzle.
8. Keep 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.
9. If fuel is spilled on clothing, change clothing immediately.
10. Never over-fill the fuel tank. Replace gas cap and tighten
securely.
11. Use extra care in handling gasoline and other fuels.
They are flammable and vapors are explosive.
12. If fuel is spilled, do not attempt to start the engine but
move the machine away from the area of spillage and
avoid creating any source of ignition until fuel vapors
have dissipated.
13. Replace all fuel tank caps and fuel container caps
securely.
Service & Maintenance
1. Never run the unit in an enclosed area where carbon
monoxide fumes may collect.
2. Keep nuts and bolts, especially blade attachment bolts,
tight and keep equipment in good condition.
3. Never tamper with safety devices. Check their proper

are not functioning properly.
4. Keep unit free of grass, leaves, or other debris build-up.
Clean up oil or fuel spillage and remove any fuel-soaked
debris. Allow machine to cool before storage.
5. If you strike an object, stop and inspect the machine.
Repair, if necessary, before restarting.
6. Never make adjustments or repairs with the engine
running.
7. Check grass catcher components and the discharge
guard frequently and replace with manufacturer’s
recommended parts, when necessary.
8. Mower blades are sharp. Wrap the blade or wear gloves,
and use extra caution when servicing them.
9. Check brake operation frequently. Adjust and service as
required.
10. Maintain or replace safety and instructions labels, as
necessary.
11. Do not remove the fuel filter when the engine is hot
as spilled gasoline may ignite. Do not spread fuel line
clamps further than necessary. Ensure clamps grip
hoses firmly over the filter after installation.
12. Do not use gasoline containing METHANOL, gasohol
containing more than 10% ETHANOL, gasoline
additives, or white gas because engine/fuel system
damage could result.
13. If the fuel tank must be drained, it should be drained
outdoors.
14. Replace faulty silencers/mufflers.
15. Use only factory authorized replacement parts when
making repairs.
16. Always comply with factory specifications on all settings
and adjustments.
17. Only authorized service locations should be utilized for
major service and repair requirements.
18. Never attempt to make major repairs on this unit
unless you have been properly trained. Improper
service procedures can result in hazardous operation,
equipment damage and voiding of manufacturer’s
warranty.
19. On multiple blade mowers, take care as rotating one
blade can cause other blades to rotate.
20. Do not change engine governor settings or over-speed
the engine. Operating the engine at excessive speed
can increase the hazard of personal injury.
21. Disengage drive attachments, stop the engine, remove
the starter insert, and disconnect the spark plug wire(s)
before: clearing attachment blockages and chutes,
performing service work, striking an object, or if the unit
vibrates abnormally. After striking an object, inspect the
machine for damage and make repairs before restarting
and operating the equipment.
22. Never place hands near the moving parts, such as a
hydro pump cooling fan, when the tractor is running.
(Hydro pump cooling fans are typically located on top of
the transaxle).
23. Units with hydraulic pumps, hoses, or motors:
WARNING: Hydraulic fluid escaping under pressure
may have sufficient force to penetrate skin and cause
serious injury. If foreign fluid is injected into the skin
it must be surgically removed within a few hours by a
doctor familiar with this form of injury or gangrene may
result. Keep body and hands away from pin holes or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, and not hands, to search for
leaks. Make sure all hydraulic fluid connections are tight
and all hydraulic hoses and lines are in good condition
before applying pressure to the system. If leaks occur,
have the unit serviced immediately by your authorized
dealer.
24. WARNING: Improper release of springs can result in
serious personal injury. Springs should be removed
by an authorized technician.
25. Models equipped with an engine radiator:
WARNING: To prevent serious bodily injury from hot
coolant or steam blow-out, never attempt to remove the
radiator cap while the engine is running. Stop the engine
and wait until it is cool. Even then, use extreme care

12-Volt Power Outlet
The 12-volt accessory plug is located in the left side pod.
It can be used to power small electronic devices. The
accessory must be rated at 9 amps or less.
NOTICE: Operating a 12-volt accessory, especially with
the engine at idle, may cause battery discharge. When
not using the accessory plug it must be covered with
the rubber plug to prevent moisture from causing a short
circuit. Entrance of water into plug can cause a short
circuit.
Parking Brake
Use the parking brake control to engage or disengage the
parking brake when the tractor is stopped (Features and
Controls).
Engage the Parking Brake - To engage the parking
brake, fully depress the brake pedal, pull UP on the
parking brake control, and release the brake pedal.
Disengage the Parking Brake - To disengage the
parking brake, fully depress the brake pedal, press DOWN
on the parking brake control, and release the brake pedal.
Automatic Controlled Traction
What is Automatic Controlled Traction?
Automatic Controlled Traction (ACT) is an exclusive feature
of our transmissions that provides improved traction. ACT
applies a preset amount of torque to both rear wheels even
if one starts slipping (a transmission without ACT will lose
traction completely if one rear wheel starts slipping). This
preset torque is just enough to provide additional traction,
and still allow the wheels to turn at dierent speeds in a
tight turn without damaging the lawn.
What to Expect from Your ACT Tractor
For the most part, while using your tractor you will not notice
ACT working, and you will simply become accustomed to
increased traction an ACT transmission provides.
Under certain circumstances the ACT system limit can
be exceeded, and one of the rear wheels may slip (for
instance if trying to turn up a hill while accelerating). This
is normal. If you start to lose traction, do not speed up.
Instead, slow to a stop, straighten the steering wheel,
and slowly accelerate. Stopping the tractor allows the
transmission to regain more traction.

Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certied oils for best performance. Other high-quality detergent oils are acceptable if classied for service SF, SG,
SH, SJ or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
WARNING
Mowing in reverse can be hazardous to bystanders.
Tragic accidents can occur if the operator is not alert to the
presence of children. Never activate the RMO if children
are present. Children are often attracted to the unit and the
mowing activity.
en
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W-30 may cause increased oil
consumption. Check oil level more frequently.

Figure 5
2. Stop the engine and remove starter insert.
3. Clean the oil ll area of any debris and remove.
4. Remove the dipstick and wipe with a clean cloth (see
Figure 6).
5. Fully insert the dipstick.
6. Remove the dipstick and check the oil level. It should be
at the FULL mark on the dipstick.
7. If FULL, insert the dipstick and tighten securely.
If LOW, add oil slowly into the engine oil ll tube (see Oil
Recommendations). After adding oil,
wait one minute, then check the oil level.
Oil Pressure
If the oil level is below the ADD mark, add oil until it reaches
the FULL mark. Start the engine and check for proper
pressure before continuing to operate.
If the oil level is between the ADD and FULL marks, do not
start the engine. Contact an authorized dealer to have the
oil pressure problem corrected.
Figure 6
Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High alti-
tude use, see below.
• Gasoline with up to 10% ethanol (gasohol) is accept-
able.
CAUTION: Do not use unapproved gasolines, such as E15
and E85. Do not mix oil in gasoline or modify the engine to
run on alternate fuels. Use of unapproved fuels will damage
the engine components and void the engine warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See the Storage section. All fuel is
not the same. If starting or performance problems occur,
change fuel providers or change brands. This engine is cer-
tied to operate on gasoline. The emissions control system
for this engine is EM (Engine Modications).

High Altitude
At altitudes over 5,000 feet (1,524 meters), a minimum 85
octane/85 AKI (89 RON) gasoline is acceptable. To remain
emissions compliant, high altitude adjustment is required.
Operation without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. See an authorized dealer for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762
meters) with the high altitude adjustment is not recommended.

Storage
WARNING
enclosed, poorly ventilated structure. Fuel
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® Advanced Formula Fuel Treatment
& Stabilizer, available wherever Briggs & Stratton genuine
service parts are sold.
For engines equipped with a FRESH START® fuel cap,
use Briggs & Stratton FRESH START® available in 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 before storage.
Engine Oil
While the engine is still warm, change the engine oil.
Before starting the unit after it has been stored:
• Check all uid 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.

Power Ratings
The gross power rating for individual gasoline engine models is labeled in accordance with SAE (Society of Automotive
Engineers) code J1940 Small Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995.
Torque values are derived at 2600 RPM for those engines with “rpm” called out on the label and 3060 RPM for all others;
horsepower values are derived at 3600 RPM. The gross power curves can be viewed at www.BRIGGSandSTRATTON.
COM. Net power values are taken with exhaust and air cleaner installed whereas gross power values are collected
without these attachments. Actual gross engine power will be higher than net engine power and is aected by, among
other things, ambient operating conditions and engine-to-engine variability. Given the wide array of products on which
engines are placed, the gasoline engine may not develop the rated gross power when used in a given piece of power
equipment. This dierence is due to a variety of factors including, but not limited to, the variety of engine components
(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 engine.

ABOUT YOUR WARRANTY
We welcome warranty repair and apologize to you for being inconvenienced. Warranty service is available only through Simplicity Authorized Service Dealers.
Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. This warranty only covers defects in materials
or workmanship. It does not cover damage caused by improper use or abuse, improper maintenance or repair, normal wear and tear, or stale or unapproved
fuel.
Improper Use and Abuse - The proper, intended use of this product is described in the Operator’s Manual. Using the product in a way not described in the
Operator’s Manual or using the product after it has been damaged will void your warranty. Warranty is not allowed if the serial number on the product has been
removed or the product has been altered or modied in any way, or if the product has evidence of abuse such as impact damage, or water/chemical corrosion
damage.
