Safety Rules and Information
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.
Do not operate this machine unless you have been trained. Reading and
understanding this operator’s manual is a way to train yourself.
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
included to help you get the most out of your equip
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.

Operator Safety
Slope Operation
Operation on slopes can be dangerous. Using the unit on a slope that is
too steep where you do not have adequate wheel traction (and control) can
cause sliding, loss of steering, control, and possible rollover. You should
not operate on a slope greater than a 5.4 foot rise over a 20 foot length (15
degrees).
Always mow across slopes, not up and down (to maintain traction on the
wheels) and avoid sudden turns or rapid speed changes. Reduce speed and
use extreme caution on ALL slopes.
Also, note that the surface condition you are on can greatly impact your
ability to safely operate this machine. Operating on wet or slippery slopes
can cause sliding and loss of steering and control. Do not operate on
slopes that are slippery, wet, or have soft soil conditions.
If you feel unsure about operating the unit on a slope, don’t do it. It’s not
worth the risk.
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 and remove objects that could be thrown by the blade BEFORE you
start mowing.
Do not operate this unit without the entire grass cacher or dischargard
(deflector) in place.
Also, do not allow anyone in the area while the unit is running! meone
does enter the area, shut the unit off immediately until they leave.
Moving Parts
This equipment has many moving parts that can injure you or
someone else. However, if you stay in the operator zone (stay
seated in the seat), and follow the safety rules in this operator’s
manual, 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 unit while it is
running! Keep safety devices (guards, shields, and switches) in
place and working.
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.

Operator Safety
Retaining Walls, Drop-offs, and Water
Retaining walls and drop-offs around steps and water are a common hazard. Give yourself a minimum of two mower widths
of clearance around these hazards and hand-trim with a walk behind mower or string trimmer. Wheels dropping over
retaining walls, edges, ditches, embankments, or into water can cause rollovers, which may result in serious injury, death, or
drowning.
Fuel and Maintenance
Always disengage all drives, shutoff the engine, and remove the
key before doing any cleaning, refueling, or servicing.
Gasoline and its vapors are extremely flammable. Do not smoke
while operating or refueling. Do not add fuel while engine is hot
or running. Allow engine to cool for at least 3 minutes prior to
adding fuel.
Do not add fuel indoors, in an enclosed trailer, garaany
other enclosed area that is not well ventilated. Gasoline spills
should be cleaned up promptly and before operation begins.
Gasoline should be stored only in sealed containers approved
fuel.
Proper maintenance is critical to the safety and performe of
your unit. Keep the unit free of grass, leaves, and excel.
Be sure to perform the maintenance procedures ld in this
manual, especially periodically testing the y system.

Smooth Travel
Zero Turn Driving Practice
The lever controls of
the Zero Turn rider are
responsive.
The lever controls of the Zero Turn rider are responsive, and
learning to gain a smooth and efficient control of the rider’s
forward, reverse, and turning movements will take some
practice.
The BEST method of
handling the ground
speed control levers is in
three steps — as shown
in Figure 9.
Spending some time going through the maneuvers shown
and becoming familiar with how the unit accelerates, travels,
and steers — before you begin mowing —is absolutely
essential to getting the most out of the Zero Turn rider.
FIRST place your hands
onto the levers as shown.
Locate a smooth, flat area of your lawn — one with
plenty of room to maneuver. (Clear the area of objects,
people and animals before you begin.) Operate the unit at
mid-throttle during this practice session (ALWAYS operate
at full throttle when mowing), and turn slowly to prevent tire
slippage and damage to your lawn.
SECOND, to go forward
gradually push the levers
forward with your palms.
THIRD, to speed up
We suggest you begin with the Smooth Travel procedure to
the right, and then advance through the forward, reverse,
and turning maneuvers.
move the levers farther
forward. To slow down
smoothly, slowly move
the levers toward neutral.
You must release the parking brake prior to moving the
ground speed control levers inward.

Reverse Travel Practice
Gradually move both ground speed control levers — evenly
FORWARD from neutral. Slow down and repeat.

NOTE: Straight forward travel takes practice. If
necessary, top speed can be balance-adjusted — see
the Speed Balancing Adjustment in the Adjustm
section near the back of this manual.
NOTE: Practice backing up for several minutes before
attempting to do so near objects. The rider turns
sharply in reverse as well as forward, and backing up
straight takes practice.

from neutral simultaneously. Repeat several times.
NOTE: To prevent pivoting directly on the tire tread,
it is best to keep both wheels going at least slightly
forward.

Executing an End-Of-Row Zero
Turn
Your Zero Turn Rider’s unique ability to turn in
place allows you to turn around at the end of a
cutting row rather than having to stop and Y-turn
before starting a new row.
For example, to execute a left end-of row zero
turn:
1. Slow down at the end of the row.
2. Move the RIGHT ground speed contro
lever forward slightly while moving the
LEFT ground speed control lever back to
center and then slightly back from center.
3. Begin mowing forward again.
This technique turns the rider LEFT and slightly
overlaps the row just cut —eliminating the need
to back up and re-cut missed grass.
As you become more familiar and
experienced with operating the Zero Turn
rider, you will learn more maneuvers that
will make your mowing time easier and
more enjoyable.
Remember, the more you practice, the
better your control of the Zero Turn will
be!

Tall Grass Requires Incremental Cutting
For extremely tall grass, set the cutting height at maximum
for the first pass, and then reset it to the desired height and
mow a second or third time.
Mowing Recommendations
Several factors can affect how well your machine cuts grass,
Following proper mowing recommendations can improve
the performance and life of your machine.
Don’t cover the grass surface with a heavy layer of
clippings. Consider using a grass collection system and
arting a compost pil
Height of Grass
Often cutting height is a matter of personal preference.
Typically, you should mow the grass when it is is between
three and five inches high. The proper cutting height
range for a specific lawn will depend upon several f,
including the type of grass, the amount of rainfall, th
prevailing temperature, and the lawn’s overll condtion.
Cut Here On
First Pass
Cut Here
On Second
Pass
Cutting the grass too short causes weak, thin grass plants,
which are easily damaged by dry periods and pests. Cutting
too short is often more damaging than allowing the grass to
be slightly higher.
Letting grass grow a bit longer—especially when it is ho
and dry—reduces heat build-up, preserves needemoisture
and protects the grass from heat damage other
problems. However, allowing grass to grotoo high can
cause thin turf and additional problems.
Figure 16. Incremental Cutting
Cutting off too much at one time shocks the plant’s growth
system and weakens the grass plants. A good rule of
thumb is the 1/3 rule: to cut no more than one
third of the grass height, and never more than 1
inch at a time.
The amount of grass you are able to cut in one pass is
also effected by the type of mowing system you are using
(for example, broadcasting with side discharge decks can
process a much larger volume of grass than mulching
does).

Operation
When and How Often to Mow
The time of day and condition of the grass greatly affect the
results you’ll get when mowing. For the best results, follow
these guidelines:
1. Mow when the grass is between three and five inches
high.
2. Mow with sharp blades. Short clippings of grass one
inch or shorter decompose more quickly than longer
blades. Sharp mower blades cut grass cleanly and
efficiently, preventing frayed edges which harm the
grass.
Where possible, make one or two passes around the
outside of the area discharging the grass INTO the
lawn to keep the cut grass off fences and walks.
3. Mow at time of day when the grass is cool and dry.
Late afternoon or early evening often provide these ideal
mowing conditions.
4. Avoid mowing after rain or even heavy dew, and never
mulch when the grass is wet (moist grass does not
mulch well, and clumps beneath the mower deck).
Mowing Patterns
Always start mowing on a smooth, level area.
The size and type of area to be mowed will determine the
best mowing pattern to use. Obstructions such as trees,
fences and buildings, and conditions such as slopes and
grades must also be considered.
remainder of thowing should be done in the
opposite directon so that the clippings are dispersed
OUT onto the area of lawn previously cut.
1. Cut long straight strips overlapping slightly.
2. Where possible, change patterns occasionally to
eliminate matting, graining or a corrugated appeace.
Mowing Methods
3. For a truly professional cut, mow across the lawn in one
direction, then recut the lawn by mowing perpendicular
to the previous cut.
Prr Broadcast Mowing
oadcasting, or side-discharging, disperses fine clippings
evenly over the entire lawn. Many golf courses use this
method. Your mower has a deep dish deck to allow freer
circulation of clippings so they are broadcast evenly over the
lawn.
Note: Always operate the engine at full throttle
when mowing.
If you hear the engine slowing down, you are mowg
too fast—using a slower ground speed will improe the
cutting efficiency of the blades and preveany common
cutting problems. Use an appropriate groud speed for the
thickness and height of the grass you are cutting (3rd gear
or slower for manual gear models). If you hear the engine
slowing down you are mowing too fast, use a slower ground
speed.
Engine Speed & Ground Speed for Broadcasting
Always operate the engine at full throttle when mowing. If
you hear the engine slowing down, you are mowing too
fast—using a slower ground speed will improve the cutting
efficiency of the blades and prevents many common cutting
problems.
ALWAYS use an appropriate ground speed for the thickness
and height of the grass you are cutting (3rd gear or slower
for manual gear models). If you hear the engine slowing
down you are mowing too fast, use a slower ground speed.
How Much Grass to Cut Off When Broadcasting
Mow when the grass is 3-5 inches long. Do not cut the
grass shorter than 2 to 2-1/2 inches. Do not cut off more
that 1 inch of grass in a single pass

Operation
Proper Mulching
Attaching A Trailer
Mulching consists of a mower deck which cuts and recuts
clippings into tiny particles and which then blows them
down INTO the lawn. These tiny particles decompose rapidly
into by-products your lawn can use. UNDER PROPER
CONDITIONS, your mulching mower will virtually eliminate
noticeable clippings on the lawn surface.
The maximum weight of a towed trailer should be less than
200 lbs (91kg). Secure the trailer with a appropriately sized
clevis pin (A, Figure 18) and clip (B).
Excessive towed loads can cause loss of traction and loss of
control on slopes. Reduce towed weight when operating on
slopes. The surface being driven on greatly impacts traction
and stability. Wet or slippery surfaces can greatly reduce
traction and the ability to stop or turn. Carefully evaluate
the surface conditions before operating the unit and trailer,
and never operate on slopes greater than 10°. See SLOPE
OPERATION and TOWED EQUIPMENT in the safety section
of this manual for additional safety information.
NOTE: When mulching under heavy cutting conditions, a
rumbling sound may be present and is normal.
Mulching Requires EXCELLENT Mowing
Conditions
Mulching mowers cannot function properly if the grass is
wet, or if the grass is simply to high to cut. Even more than
normal mowing, mulching requires that the grass be dry and
the the appropriate amount is cut.
Do not use the mower as a mulching mower during the first
two or three mowings in the spring. The long grass blades,
quick growth, and often wetter conditions are more suitable
for broadcasting (side-discharging) or grass bagging
operation.
A
Engine Speed & Ground Speed for Mulching
Use full engine throttle matched with a slow ground speed
so that clippings will be finely cut. Ground speed while
mulching should be HALF of the speed that would be
used when broadcasting (side discharging) under similar
conditions. Since mulching requires more horsepowe
than broadcasting, using a slower ground speed is
important for proper mulching operation.
B
How Much Grass to Mulch
The best mulching action typically results from cutting only
the top 1/2 inch to 3/4 inch of grass blade. This provides
short clippings which decompose properly (much mor
quickly than longer clippings). The ideal cutting height w
vary with climate, time of year, and quality of youawn. We
recommend that you experiment with botcutting height
and ground speed until you achieve the bcut. Start with
a high cutting height and using progressively lower settings
until you find a cutting height that is matched to your
mowing conditions and preferences.

Jump Starting With Auxiliary (Booster) Battery
Battery Service
Jump starting is not recommended. However, if it must be
done, follow these directions. Both booster and dis-charged
batteries should be treated carefully when using jumper
cables. Follow the steps below EXACTLY, being careful not
to cause sparks. Refer to Figure 45.
Checking Battery Voltage
WARNING
Keep open flames and sparks away from the battery;
the gasses coming from it are highly explosive.
Ventilate the battery well during charging.
1. Both batteries must be of the same voltage.
2. Position the vehicle with the booster battery adjacent to
the vehicle with the discharged battery so that booster
cables can be connected easily to the batteries in both
vehicles. Make certain vehicles do not touch each other.
3. Wear safety glasses and shield eyes and face from
batteries at all times. Be sure vent caps are tight. Place
damp cloth over vent caps on both batteries.
A voltmeter can be used to determine condition of battery.
When engine is off, the voltmeter shows battery voltage,
which should be 12 volts. When engine is running, the
voltmeter shows voltage of charging circuit which normally
is 13 to 14 volts.
4. Connect positive (+) cable to positive post of discharged
battery (wired to starter or solenoid).
5. Connect the other end of same cable to same post
marked positive (+) on booster battery.
6. Connect the second cable negative (-) to other post of
booster battery.
7. Make final connection on engine block of stalled vehicle
away from battery. Do not lean over batteries.
Start the engine ovehicle with the booster battery.
Wait a few minutes, then attempt to start the engine of
the vehicle with the discharged battery.
9. If the vehicle does not start after cranking for thirty
seconds, STOP PROCEDURE. More than thirty seconds
eldom starts the engine unless some mechanical
ustment is made.
0. After starting, allow the engine to return to idle speed.
Remove the cable connection at the engine or frame.
Then remove the other end of the same cable from the
booster battery.
11. Remove the other cable by disconnecting at the
discharged battery first and then disconnect the opposite
end from the booster battery.
A dead battery or one too weak to start the engine may not
mean the battery needs to be replaced. For example, it may
mean that the alternator is not charging the battery properly.
If there is any doubt about the cause of the problem, see
your dealer. If you need to replace the battery, follow the
steps under Cleaning the Battery & Cables in the Regular
Maintenance Section.
Charging a Completely Discharged Battery
1. Be aware of all the safety precautions you should
observe during the charging operation. If you are
unfamiliar with the use of a battery charger and
hydrometer, have the battery serviced by your d
2. Add distilled water sufficient to cover the plate (fill to the
proper level near the end of the charge). If the battery
is extremely cold, allow it to warm before adding water
because the water level will rise as it warms. Also, an
extremely cold battery will not accept a normal charge
until it becomes warm.
3. Always unplug or turn the charger off before attachi
or removing the clamp connections.
4. Carefully attach the clamps to the batn proper
polarity (usually red to [+] positive and black to [-]
negative).
12. Discard the damp cloths that were placed over the
battery vent caps.
5. While charging, periodically measure the temperature of
the electrolyte. If the temperature exceeds 125° F (51.6°
C), or if violent gassing or spewing of electrolyte occurs,
the charging rate must be reduced or temporarily halted
to prevent battery damage.
6. Charge the battery until fully charged (until the specific
gravity of the electrolyte is 1.250 or higher and the
electrolyte temperature is at least 60° F). The best
method of making certain a battery is fully charged, but
not over charged, is to measure the specific gravity of
a cell once per hour. The battery is fully charged when
the cells are gassing freely at low charging rate and less
than 0.003 change in specific gravity occurs over a three
hour period.

Storage
WARNING
Temporary Storage (30 Days Or Less)
Never store the unit, with gasoline in engine or
fuel tank, in a heated shelter or in enclosed, poorly
ventilated enclosures. Gasoline fumes may reach an
open flame, spark or pilot light (such as a furnace,
water heater, clothes dryer, etc.) and cause an
explosion.
Remember, the fuel tank will still contain some gasoline, so
never store the unit indoors or in any other area where fuel
vapor could travel to any ignition source. Fuel vapor is also
toxic if inhaled, so never store the unit in any structure used
for human or animal habitation.
Handle gasoline carefully. It is highly flammable and
careless use could result in serious fire damage to
your person or property.
Drain fuel into an approved container outdoors away
from open flame or sparks.

WARNING
While normal care and regular maintenance will extend
the life of your equipment, prolonged or constant use may
eventually require that service be performed to allow it to
continue operating properly.
To avoid serious injury, perform maintenance on the
tractor or mower only when the engine is stopped and
the parking brake engaged.
Always remove the ignition key, disconnect the spark
plug wire and fasten it away from the plug before
beginning the maintenance, to prevent accidental
starting of the engine.
The troubleshooting guide below lists the most common
problems, their causes and remedies.
See the information on the following pages for instructions
on how to perform most of these minor adjustments
and service repairs yourself. If you prefer, all of these
procedures can be performed for you by your local
authorized dealer.

wer 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; horsepower values are
derived at 3600 RPM. The gross power curves can be viewed at
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, ambient 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.

California, U.S. EPA, and Briggs & Stratton Corporation Emissions Control Warranty Statement
Your Warranty Rights And Obligations
The California Air Resources Board, U.S. EPA, and Briggs & Stratton (B&S) are pleased
Owner’s Warranty Responsibilities:
to explain the emissions control system warranty on your Model Year 2012--2013
engine/equipment. In California, new small off-road engines and large spark ignited

belts, connectors, sensors, and other emissions-related assemblies.
As the engine/equipment owner, you are responsible for the performance of the
required maintenance listed in your owner’s manual. B&S recommends that you
retain all receipts covering maintenance on your engine/equipment, but B&S cannot
deny warranty solely for the lack of receipts or your failure to ensure the performance
of all scheduled maintenance.
As the engine/equipment owner, you should however be aware that B&S may deny
you warranty coverage if your engine/equipment or a part has failed due to abuse,
neglect, improper maintenance, or unapproved modifications.
You are responsible for presenting your engine/equipment to a B&S distribution
center, servicing dealer, or other equivalent entity, as applicable, as soon as a
problem exists. The warranty repairs should be completed in a reasonable amount of
time, not to exceed 30 days. If you have any questions regarding your warranty
rights and responsibilities, you should contact B&S at (414) 259-5262.
Where a warrantable condition exists, B&S will repair your engine/equipment at no cost

any related emissions components of the equipment, are warranted for two years*. If any
emissions-related part on your B&S engine/equipment is defective, the part will be
repaired or replaced by B&S.
*
Two years or for the time period listed in the respective engine or product warranty
statement, whichever is greater.
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 epaired or replaced by B&S at no charge to the

warranty period.
Any waranted 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
schedued 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
arranted for the remainder of the period prior to the first scheduled
placement point for the part.
b. Air Induction System

Purge and vent line
c. Ignition System
Spark plug(s)
Magneto ignition system
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
not be liable to warrant failures of warranted parts caused by the use of a non
exempted add on or modified part.
d. Catalyst System
Catalytic converter
Exhaust manifold
Air injection system or pulse valve
3. Consequential Coverage
e. Miscellaneous Items Used in Above Systems
Vacuum, temperature, position, time sensitive valves and hes
Connectors and assemblies
Coverage shall extend to the failure of any engine components caused by the
failure of any warranted emissions parts.
2. Length of Coverage
4. Claims and Coverage Exclusions
For a period of two years from date of original purchase, Barrants 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.
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.
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
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.
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.
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.
