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 commonsense,andthinkthroughwhat youaredoing.If youarenot
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 autho-
rized 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 fol-
lowing pages. Also completely read the Operation section.
Children
Reverse
Tragic accidents can occur with children. Do not allow them any- Do not mow in reverse unless absolutely
where near the area of operation. Children are often attracted
necessary. Always look down and
to the unit and mowing activity. Never assume that children will
behind before and while traveling
remain where you last saw them. If there is a risk that children
in reverse even with the mower
may enter the area where you are mowing, have another respon- blades disengaged.
sible adult watch them.
DO NOT GIVE CHILDREN RIDES ON THIS UNIT! This encour-
ages them to come near the unit in the future while it is running,
andtheycouldbeseriouslyhurt.Theymaythenapproachthe
unit for a ride when you are not expecting it, and you may run
over them.

Operator Safety
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 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 (deflec-
tor) 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 sol-
vent 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.

Operator Safety
WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects
!
that can cause injury and damage! Failure to comply with the following SAFETY instructions could result in
serious injury or death to the operator or other persons. The owner of the machine must understand these
instructions and must allow only persons who understand these instructions to operate machine. Each
person operating the machine must be of sound mind and body and must not be under the influence of any
substance, which might impair vision, dexterity or judgment.
Protection Against Tip-Overs/Roll-Overs
Slopes are a major factor related to loss-of-control and tip-
over/roll-over accidents, which can result in severe injury
or death. All slopes require extra CAUTION. If you cannot
back up the slope or if you feel uneasy on the slope, DO
NOT mow it. Use extra care with grass catchers or other
attachments; these affect the handling and the stability of
the machine.
WARNING
POISONOUS GAS HAZARD. Engine exhaust contains carbon
monoxide, a poisonous gas that could kill you in minutes. You
CANNOT see it, smell it, or taste it. Even if you do not smell
exhaust fumes, you could still be exposed to carbon monox-
ide gas. If you start to feel sick, dizzy, or weak while using this
product, shut it off and get to fresh air RIGHT AWAY. See a
doctor. You may have carbon monoxide poisoning.
•
•
•
Operate this product ONLY outside far away from windows, doors and
vents to reduce the risk of carbon monoxide gas from accumulating and
potentially being drawn towards occupied spaces.
Install battery-operated carbon monoxide alarms or plug-in carbon
monoxide alarms with battery back-up according to the manufacturer’s
instructions. Smoke alarms cannot detect carbon monoxide gas.
DO NOT run this product inside homes, garages, basements, crawlspac-
es, sheds, or other partially-enclosed spaces even if using fans or open-
ing doors and windows for ventilation. Carbon monoxide can quickly
build up in these spaces and can linger for hours, even after this product
has shut off.
1. DO NOT operate machine on slopes exceeding 10
degrees (18% grade).
2. Turn blades OFF when traveling uphill. Use a slow
speed and avoid sudden or sharp turns.
3. DO NOT operate machine back and forth across face of
slopes. Operate up and down. Practice on slopes with
blades off.
4. AVOID starting, stopping or turning on slopes. If
machine stops going uphill or tires lose traction, turn
blades OFF and back slowly straight down the slope.
5. STAY ALERT for holes and other hidden hazards. Tall
grass can hide obstacles. Keep away from ditches,
washouts, culverts, fences and protruding objects.
6. KEEP A SAFE DISTANCE (at least two mower widths)
away from edge of ditches and other drop offs. The
machine could turn over if an edge caves in.
7. Always begin forward motion slowly and with caution.
8. DO NOT begin forward motion while the machine is roll-
ing backwards. A rearward tip-over may result.
9. Use weights or a weighted load carrier in accordance
with instructions supplied with a grass catcher or other
attachments. DO NOT operate machine on slopes
exceeding 10 degrees (18% grade) when equipped with
grass catcher or other attachments.
•
ALWAYS place this product downwind and point the engine exhaust
away from occupied spaces.
Protection for Children
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
machine and the mowing activity. 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. 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 a responsible adult other than the
operator.
2. DO NOT allow children in yard when machine is
operated (even with the blade OFF).
3. DO NOT allow children or others to ride on machine,
attachments or towed equipment (even with the blades
OFF). They may fall and be seriously injured.
4. DO NOT allow pre-teenage children to operate machine.
5. ALLOW only responsible adults & teenagers with mature
judgment under close adult supervision to operate
machine.
6. DO NOT operate blades in reverse unless absolutely
necessary. STOP BLADES. LOOK and SEE behind and
down for children, pets and hazards before and while
backing.
7. USE EXTRA CARE when approaching blind corners,
shrubs, trees, or other objects that may obscure vision.
10. DO NOT put your foot on the ground to try to stabilize
the machine.
11. DO NOT operate machine on wet grass. Reduced trac-
tion could cause sliding.
12. Choose a low enough speed setting so that you will not
have to stop or shift on a slope. Tires may lose traction
on slopes even though the brakes are functioning prop-
erly.
13. DO NOT operate machine under any condition where
traction, steering or stability is doubtful.
14. Always keep the machine in gear when going down
slopes. DO NOT shift to neutral (or actuate hydro roll
release) and coast downhill.
15.Machine stability is tested in accordance with the appli-
cable ANSI B71 standard using an operator weight of
200 lbs. To minimize the risk of a tip-over or roll-over,
operators weighing more than 200 lbs. should further
limit the ground speed and the degree of slope to be
mowed.

in this manual and on the machine, engine and attach-
ments. Know the controls and the proper use of the
machine before starting.
8. DO NOT start gas powered equipment in enclosed
vehicles or trailers.
2. Only mature, responsible persons shall operate the
machine and only after proper instruction.
3. Data indicates that operators age 60 and above, are
involved in a large percentage of mower-related injuries.
These operators should evaluate their ability to operate
the mower safely enough to protect themselves and oth-
ers from serious injury.
4. Handle fuel with extra care. Fuels are flammable and
vapors are explosive. Use only an approved fuel con-
tainer. DO NOT remove fuel cap or add fuel with engine
running. Add fuel outdoors only with engine stopped and
cool. Clean spilled fuel from machine. DO NOT smoke.
5. Practice operation of machine with BLADES OFF to
learn controls and develop skills.
9. Keep the 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
10. If fuel is spilled on clothing, change clothing immedi-
ately.
11. Never overfill a fuel tank. Replace fuel cap and tighten
securely.
Operation
1. Mount and dismount machine from left side. Keep clear
of discharge opening at all times.
2. Start engine from operator’s seat, if possible. Make sure

stantial footwear.
11. Know how to STOP blades and engine quickly in prepa-
ration for emergencies.
12. Use extra care when loading or unloading the machine
into a trailer or truck.
13. Check grass catcher components frequently for signs of
wear or deterioration and replace as needed to prevent
injury from thrown objects going through weak or worn
spots.
13. Exercise CAUTION when pulling loads. Limit loads to
those you can safely control and attach loads to hitch
plate as specified with attachment instructions.
14. On slopes, the weight of the towed equipment may
cause loss of traction and loss of control. When towing,
travel slowly and allow extra distance to stop.
15. DO NOT operate engine in enclosed areas. Engine
exhaust gases contain carbon monoxide, a deadly poi-
son.
16. DO NOT discharge material against a wall or obstruc-
tion. Material may ricochet back towards the operator.
17. Only use accessories approved by the manufacturer.
See manufacturer’s instructions for proper operation and
installation of accessories.
Safe Handling of Gasoline
To avoid personal injury or property damage, use extreme
care in handling gasoline. Gasoline is extremely flammable
and the vapors are explosive.
1. Extinguish all cigarettes, cigars, pipes and other sources
of ignition.
2. Use only an approved fuel container.

Operation
Fuel Recommendations
A
Fuel must meet these requirements:
•
•
Clean, fresh, unleaded gasoline.
A minimum of 87 octane/87 AKI (91 RON). High altitude
use, see below.
•
Gasoline with up to 10% ethanol (gasohol) is accept-
able.
NOTICE: 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. This will damage the engine compo-
nents and void the engine warranty.
B
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. Refer to “Storage”. All fuel is not the
same. If starting or performance problems occur, change fuel
providers or change brands. This engine is certified to oper-
ate on gasoline. The emissions control system for this engine
is EM (Engine Modifications)

How To Adjust The Operator Seat
With the engine stopped:
1. Raise the operator seat.
2. Loosen the two adjusting knobs (A, Figure 3) and move
the seat to the desired position. After adjustment, tighten
the knobs securely.
High Altitude
At altitudes over 5,000 feet (1524 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 per-
formance, increased fuel consumption, and increased emis-
sions. See a Briggs & Stratton Authorized Dealer for high
altitude adjustment information.
3. Lower the operator seat.
Operation of the engine at altitudes below 2,500 feet (762
meters) with the high altitude adjustment is not recommend-
ed.

4. Start the engine and allow it to run until the engine runs
out of fuel. This allows the carburetor and fuel system to
remain clean during storage.
5. Remove and store the battery. Refer to “How To Store
The Battery”.
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 con-
centrate 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.
If gasoline in the engine has not been treated with a fuel sta-
bilizer, 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 main-
tain freshness.

WARNING
Wear heavy leather gloves when handling or working
around cutting blades. Blades are extremely sharp and can
cause severe injury.
Figure 37: Mower deck leveling (side-to-side)
Side-To-Side Leveling
Before making deck leveling adjustments, check the tire
pressure. Refer to “How To Check Tire Pressure”. If tires
are properly inflated and mowing is still uneven, adjust side-
to-side deck leveling.
1. Place the unit on a smooth level surface.
2. Turn the engine off and remove the key. Remove the
spark plug wire from the spark plug and secure the wire
away from the plug.
3. Raise the mower deck to the highest cutting position.
4. Place a piece of angle iron, pipe, or similar object under
the rear center of the deck.
Front-to-Rear Leveling
NOTE: Perform side-to-side leveling first.
1. With the unit on a smooth, level surface, rotate the blade
until the blade tips are at the front and rear of the deck.
2. Measure the distance from the blade tips to the floor
(Figure 38). The distance should be the same, or the
rear 1/8” to 1/4” lower than the front. If the rear blade tip
is higher than the front, or is more than 1/4” lower than
the front, proceed with adjustment.
5. Lower the mower deck until the rear of the deck is sup-
ported by the object placed under it in the previous step.
(The rear hanger rods (A, Figure 38) should be loose.)
6. Wearing heavy leather gloves, rotate the blade until the
blade tips are positioned at the right and left sides of the
mower deck. Measure the distance from the blade tips
to the floor. If the measurement is within 1/8” from side-
to-side, the deck is considered level. If difference from
side-to-side is greater than 1/8”, continue with adjust-
ment.
3. If adjustment is needed, turn the lock nut (B, Figure 38)
on both left and right hanger rods (A) the same number
of rotations to raise or lower the rear of the deck.
4. Measure the blade tips again.
5. Repeat Steps 2 through 4 until proper leveling is
obtained.

Briggs & Stratton Emissions Control Warranty Provisions
The following are specific provisions relative to your Emissions Control Warranty Coverage. It is in addition to the B&S engine warranty for non-regulated engines found in the
Operator’s Manual.
1. Warranted Emissions Parts
The warranty on emissions-related parts is as follows:
Coverage under this warranty extends only to the parts listed below (the emissions
control systems parts) to the extent these parts were present on the B&S engine
and/or B&S supplied fuel system.
Any warranted part that is not scheduled for replacement as required
maintenance in the owner’s manual supplied, is warranted for the warranty
period stated above. If any such part fails during the period of warranty
coverage, the part will be repaired or replaced by B&S at no charge to the
owner. Any such part repaired or replaced under the warranty will be warranted
for the remaining warranty period.
Any warranted part that is scheduled only for regular inspection in the owner’s
manual supplied, is warranted for the warranty period stated above. Any such
part repaired or replaced under warranty will be warranted for the remaining
warranty period.
Any warranted part that is scheduled for replacement as required maintenance
in the owner’s manual supplied, is warranted for the period of time prior to the
first scheduled replacement point for that part. If the part fails prior to the first
scheduled replacement, the part will be repaired or replaced by B&S at no
charge to the owner. Any such part repaired or replaced under warranty will be
warranted for the remainder of the period prior to the first scheduled
replacement point for the part.
Add on or modified parts that are not exempted by the Air Resources Board
may not be used. The use of any non exempted add on or modified parts by the
owner will be grounds for disallowing a warranty claim. The manufacturer will

4. Claims and Coverage Exclusions
Vacuum, temperature, position, time sensitive valves and switches
Connectors and assemblies
2. Length of Coverage
Warranty claims shall be filed according to the provisions of the B&S engine
warranty policy. Warranty coverage does not apply to failures of emissions parts
that are not original equipment B&S parts or to parts that fail due to abuse, neglect,
or improper maintenance as set forth in the B&S engine warranty policy. B&S is not
liable for warranty coverage of failures of emissions parts caused by the use of
add-on or modified parts.
For a period of two years from date of original purchase*, B&S warrants to the
original purchaser and each subsequent purchaser that the engine is designed, built,
and equipped so as to conform with all applicable regulations adopted by the Air
Resources Board; that it is free from defects in material and workmanship that could
cause the failure of a warranted part; and that it is identical in all material respects to
the engine described in the manufacturer’s application for certification. The warranty
period begins on the date the engine is originally purchased.
*
Two years or for the time period listed in the respective engine or product
warranty statement, whichever is greater.
Look For Relevant Emissions Durability Period and Air Index Information
On Your Small Off-Road Engine Emissions Label
Engines that are certified to meet the California Air Resources Board (CARB) small
off-road 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.
Briggs & Stratton engines are certified to meet the United States Environmental
Protection Agency (USEPA) Phase 2 or Phase 3 emissions standards. 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.
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:
For engines less than 225 cc displacement.
Category C = 125 hours, Category B = 250 hours, Category A = 500 hours
Moderate:
For engines of 225 cc or more displacement.
Category C = 250 hours, Category B = 500 hours, Category A = 1000 hours
Engine is certified to be emissions compliant 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.
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.

* Power Ratings: 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; horse-
power 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 affected by, among other things, ambi-
ent operating conditions and engine-to-engine variability. Given the wide array of products on which engines are placed, the
gas engine may not develop the rated gross power when used in a given piece of power equipment. This difference 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 Series engine.
