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.
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.
Safe Operation Practices

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 foot rise over a 20 foot 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 aect 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
operator-present 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
(deector) in place.
Do not allow anyone in the mowing area while the unit is running! If someone
does enter the area, shut the unit o 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.
10

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 mow-
ing. 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 travel-
ling in reverse.
8. Never direct discharge material toward anyone. Avoid
discharging material against a wall or obstruction. Ma-
terial 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 (deector), or other safety
devices in place.
10. Slow down before turning.
11. Never leave a running unit unattended. Always dis-
engage the PTO, set parking brake, stop engine, and
remove keys before dismounting.
12. Disengage blades (PTO) when not mowing. Shut o
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 articial
light.
14. Do not operate the unit while under the inuence of
alcohol or drugs.
15 Watch for trac when operating near or crossing
roadways.
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
equipment-related 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 adjust-
ment can be made from the operator’s position).
25. When the machine is parked, stored, or left unat-
tended, lower the cutting means unless a positive me-
chanical 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 re hazard, keep the unit free of grass,
leaves, & excess oil. Do not stop or park over dry
leaves, grass, or combustible materials.
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 signi-
es 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 prac-
tices 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 ig-
nition 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 stor-
age 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
there is an open ame or pilot light, such as in a water
heater. Allow unit to cool before storing.

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 o 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) o. They
may fall o 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 vi-
sion.
EMISSIONS
1. Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth de-
fects, or other reproductive harm.
2. Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tip-
over 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: insucient 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 distribu-
tion.
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 down-
hill.
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 aect the sta-
bility 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-os, ditches, or embankments.
The mower could suddenly turn over if a wheel is over
the edge of a cli 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 recommenda-
tions 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 equip-
ment.
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.
12
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.

SERVICE AND MAINTENANCE
Safe Handling of Gasoline
1. Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.
2. Use only approved gasoline containers.
3. Never remove the gas cap or add fuel with the engine
running. Allow the engine to cool before refueling.

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 rec-
ommended 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 lter when the engine is hot as
spilled gasoline may ignite. Do not spread fuel line
clamps further than necessary. Ensure clamps grip
hoses rmly over the lter after installation.
12. Do not use gasoline containing METHANOL, gasohol
containing more than 10% ETHANOL, gasoline addi-
tives, or white gas because engine/fuel system dam-
age could result.
13. If the fuel tank must be drained, it should be drained
outdoors.
14. Replace faulty silencers/muers.
15. Use only factory authorized replacement parts when
making repairs.
16. Always comply with factory specications on all set-
tings 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 un-
less you have been properly trained. Improper service
procedures can result in hazardous operation, equip-
ment 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, re-
move the key, 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, in-
spect the machine for damage and make repairs be-
fore 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: WARN-
ING: Hydraulic uid escaping under pressure may
have sucient force to penetrate skin and cause
serious injury. If foreign uid 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 uid under high pressure.
Use paper or cardboard, and not hands, to search for
leaks. Make sure all hydraulic uid connections are
tight and all hydraulic hoses and lines are in good con-
dition before applying pressure to the system. If leaks
occur, have the unit serviced immediately by your au-
thorized dealer.
24. WARNING: Stored energy device. Improper re-
lease of springs can result in serious personal injury.
Springs should be removed by an authorized techni-
cian.
25. Models equipped with an engine radiator: WARNING:

This opens the catcher so that it may be emptied and
closes it for mowing. To empty the catcher, extend the
grass catcher handle and pull forward on the handle. To
close, push the lever backward until the catcher closes
and locks. Release the grass catcher handle.
Transmission Release Lever
This deactivates the transmission so that the tractor can be
pushed by hand. See Pushing the Tractor By Hand.

Test 1 — Engine should NOT crank if:
• PTO switch is ON, OR
• Brake pedal is NOT fully depressed (parking brake
OFF), OR
• The cruise control lever is NOT in NEUTRAL.
Test 2 — Engine SHOULD crank and start if:
• Operator is sitting in seat, AND.
• PTO switch is OFF, AND
• Brake pedal is fully depressed (parking brake ON),
AND
• The cruise control lever is in NEUTRAL.
Test 3 — Engine should SHUT OFF if:
• Operator rises o seat.
Test 4 — Check Mower Blade Stopping Time
Mower blades and mower drive belt should come to a
complete stop within ve seconds after electric PTO
switch is turned OFF. If mower drive belt does not stop
within ve seconds, see an authorized dealer.
Test 5 — Check Reverse Mow Option RMO
• Engine should shut o if reverse travel is attempted if
the PTO has been switched on and RMO has not been
activated.
• RMO light should illuminate when RMO has been acti-
vated.
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certied oils for best performance. Other high-quality de-
tergent oils are acceptable if classied 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.
* 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.
Safety Interlock System Tests
This unit is equipped with safety interlock switches and
other safety devices. These safety systems are present for
your safety: do not attempt to bypass safety switches, and
never tamper with safety devices.

WARNING
If the unit does not pass a safety test, do not oper-
ate it. See an authorized dealer.
WARNING
Mowing in reverse can be hazardous to bystand-
ers.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.

Check Tire Pressure
Tires should be checked periodically to provide the
optimum traction and to guarantee the best cut (see
Figure 4).
NOTE: These pressures may dier slightly from the
“Maximum Ination” stamped on the side walls of the tires.

Oil Pressure
If the oil pressure is too low, a pressure switch (if equipped)
will either stop the engine or activate a warning device on
the equipment. If this occurs, stop the engine and check
the oil level with the dipstick.
If the oil level is below the ADD mark, add oil until it reaches
the FULL mark. Start the engine and check for proper pres-
sure 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. 1. Pull up tractor hood to access the fuel tank.
2. Clean the fuel cap area of dirt and debris. Remove
the fuel cap (A, Figure 6).
3. Fill the fuel tank (B) with fuel. To allow for expansion
of the fuel, do not ll above the bottom of the fuel tank
neck.
4. Reinstall the fuel cap.

Checking/Adding Oil
Before adding or checking the oil
• Place engine level.
• Clean the oil ll area of any debris.
1. Remove the dipstick (A, Figure 5) and wipe with a
clean cloth.
2. Insert and tighten the dipstick.
3. Remove the dipstick and check the oil level. It should
be at the FULL mark (B) on the dipstick.
4. If low, add oil slowly into the engine oil ll (C). Do not
overll. After adding oil, wait one minute and then
recheck the oil level.
NOTE: Do not add oil at the quick oil drain (if equipped).
5. Replace and tighten the dipstick.
High Altitude
At altitudes over 1,524 meters (5,000 feet), 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 ad-
justment information.
Operation of the engine at altitudes below 762 meters
(2,500 feet) with the high altitude kit is not recommended.
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) or up to
15% MTBE (methyl tertiary butyl ether) is acceptable.
CAUTION: Do not use unapproved gasolines, such as
E85. Do not mix oil in gasoline or modify the engine to run
on alternate fuels. This will damage the engine compo-
nents 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
certied to operate on gasoline. The emissions control sys-
tem for this engine is EM (Engine Modications).
WARNING
Fuel and its vapors are extremely ammable and
explosive.
Fire or explosion can cause severe burns or
death.
When Adding Fuel
• Turn engine o and let engine cool at least 3 minutes
before removing the fuel cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overll fuel tank. To allow for expansion of the
fuel, do not ll above the bottom of the fuel tank neck.
• Keep fuel away from sparks, open ames, pilot lights,
heat, and other ignition sources.
• Check fuel lines, tank, cap, and ttings frequently for
cracks or leaks. Replace if necessary.
• If fuel spills, wait until it evaporates before starting
engine.
