found on the following pages. Also completely read the
Operation section.

Children

The safety alert triangle in text signifies important cautions
or warnings which must be followed.

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.

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.

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.

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.

Roll Bar Use (For Models Equipped with a Rigid
Roll Bar)

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 catcher or
discharge guard (deflector) in place.

Also, do not allow anyone in the area while the unit is running!
If someone does enter the area, shut the unit off immediately
until they leave.

Keep the roll bar in position and fasten the seat belt. Do not
jump off if the mower tips (it is safer to be secured by the seat
belt.)

NEVER remove the roll bar.

Roll Bar Use (For Models Equipped with a Folding
Roll Bar)

Keep the roll bar in the raised position and fasten the seat belt.
There is no roll over protection when the roll bar is down! Do
not jump off if the mower tips (it is safer to be secured by the
seat belt with the roll bar raised.)

5

Not for

Reproduction

Lower the roll bar only when necessary (such as to temporarily
clear a low overhanging obstacle) and NEVER remove it. Do
NOT use the seat belt when the roll bar is down. Raise the roll
bar as soon as clearance permits.

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.

Overhead Obstacles

Check for overhead clearances before driving under any objects.
Do not allow the roll bar to contact low overhanging obstacles
such as tree branches and guide wires.

Fuel and Maintenance

Gasoline should be stored only in sealed containers approved
for fuel.

Proper maintenance is critical to the safety and performance of
your unit. Keep the unit free of grass, leaves, and excess oil.
Be sure to perform the maintenance procedures listed in this
manual, especially periodically testing the safety system.

Enclosed Areas

Only operate this unit outdoors and away from unventilated
areas such as inside garages or enclosed trailers. The engine
emits poisonous carbon monoxide gas and prolonged exposure
in an enclosed area can result in serious injury or death.

Training

• Read, understand, and follow all instructions in the manual
and on the unit before starting. If the operator(s) or
mechanic(s) can not read English it is the owner’s
responsibility to explain this material to them.

WARNING

Do not use this machine on slopes greater than 15°.*

Select slow ground speed before driving onto slope. Use extra
caution when operating on slopes with rear-mounted grass
catchers.

Mow across the face of slopes, not up and down, use caution
when changing directions and DO NOT START OR STOP
ON SLOPE.

* This limit was determined per CEN Standard EN 836:1997, Section 5.2.2
and is based on the EN 836 Stability Test procedure described in Section

4.2.4.2. The 15 degree “limit of stability” is equal to 50% of the angle at
which machine lift-off occurred in static tests. Actual dynamic stability may
vary depending on operating conditions.

Do:

• Mow across slopes, not up and down.

• Remove obstacles such as rocks, tree limbs, etc.

• Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.

• Use slow speed. Choose a slow speed so that you will not
have to stop or change speed while on the slope.

• Use extra care with grass catchers or other attachments.
These can change the stability of the unit.

• Keep all movement on the slopes slow and gradual. Do not
make sudden changes in speed or direction.

• See your authorized dealer for recommendations of
available weights to improve stability.

Do NOT:

• Avoid starting, stopping, or turning on a slope. If tires lose
traction (i.e. machine stops forward motion on a slope),
disengage the blade(s) (PTO) and drive slow off the slope.

• Do not turn on slopes unless necessary, and then, turn
slowly and gradually uphill, if possible. Never mow down
slopes.

• Do not mow near drop-offs, ditches, or embankments. The
operator could lose footing or balance or mower could
suddenly turn over if a wheel is over the edge of a cliff or
ditch, or if an edge caves in.

• Do not mow on wet grass. Reduced footing or traction could
cause sliding.

• Do not try to stabilize the unit by putting your foot on the
ground. (ride-on units).

• Do not mow excessively steep slopes.

• Do not use grass catcher on steep slopes.

• Do not mow slopes if you cannot back up them.

Towed Equipment (Ride-On Units)

• Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the hitch
point.

• Follow the manufacturer’s recommendations for weight limit
for towed equipment and towing on slopes. See attaching
a trailer under OPERATION.

• Never allow children or others in or on towed equipment.

• On slopes, the weight of the towed equipment may cause
loss of traction and loss of control.

• Travel slowly and allow extra distance to stop.

• Do not shift to neutral and coast down hill.

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.

• Keep children out of the mowing area and under the
watchful care of another responsible adult.

• Be alert and turn unit off if children enter the area.

• Before and during reverse operation, look behind and down
for small children.

• 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.

• Never allow children to operate the unit.

• Use extra care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.

Features & Controls

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.

We suggest you begin with the Smooth Travel procedure to the
right, and then advance through the forward, reverse, and
turning maneuvers.

You must release the parking brake prior to moving the control
levers inward.

Smooth Travel

The lever controls of the Zero Turn rider are responsive.

The BEST method of handling the ground speed control levers
is in three steps — as shown in Figure 6.

Stopping the Rider

1. Returning the ground speed control levers to the middle
position will stop rider movement. Pivot the levers outward
and lock them in NEUTRAL.

2. Disengage the PTO by pushing down on the PTO switch.

3. Engage the parking brake by pulling the handle up until it
locks into position.

4. Move the throttle control to mid-throttle position and turn
the ignition key to OFF. Remove the key.

Zero-Turn Driving Practice

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.

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.

SECOND, to go forward gradually push the levers forward with

your palms.

THIRD, to speed up move the levers farther forward. To slow
down smoothly, slowly move the levers toward neutral.

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.

To turn in place, “Zero Turn,” gradually move one ground speed
control lever forward from neutral and one lever back from
neutral simultaneously. Repeat several times.

NOTE: Changing the amount each lever is pulled—forward or
back, changes the “pivot point” you turn on.

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 control 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.

Height of Grass

Often cutting height is a matter of personal preference. Typically,
you should mow the grass when it is between three and five
inches high. The proper cutting height range for a specific lawn
will depend upon several factors, including the type of grass,
the amount of rainfall, the prevailing temperature, and the lawn’s
overall condition.

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 hot and
dry—reduces heat build-up, preserves needed moisture and
protects the grass from heat damage and other problems.
However, allowing grass to grow too high can cause thin turf
and additional problems.

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.

12

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!

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.

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).

Tall grass requires incremental cutting. For extremely tall
grass, set the cutting height at maximum for the first pass (A,
Figure 13), and then reset it to the desired height and mow a
second (B) or third time.

Don’t cover the grass surface with a heavy layer of clippings.
Consider using a grass collection system and starting a compost
pile.

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:

• Mow when the grass is between three and five inches high.

• 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.

• Mow at time of day when the grass is cool and dry. Late
afternoon or early evening often provide these ideal mowing
conditions.

• 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.

• Cut long straight strips overlapping slightly.

• Where possible, change patterns occasionally to eliminate
matting, graining or a corrugated appearance.

• For a truly professional cut, mow across the lawn in one
direction, then re-cut the lawn by mowing perpendicular to
the previous cut.

NOTE: 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. 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.

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.

15

The remainder of the mowing should be done in the opposite
direction so that the clippings are dispersed OUT onto the area
of lawn previously cut.

Mowing Methods

Broadcast Mowing

Broadcasting, 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.

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.

Mulching

19

Not for

Reproduction

Mulching consists of a mower deck which cuts and re-cuts
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.

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
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.

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 horsepower than broadcasting, using
a slower ground speed is vitally important for proper mulching
operation.

How Much Grass to Mulch:

The best mulching action typically results from cutting only the
top ½ inch to 3/4 inch of grass blade. This provides short
clippings which decompose properly (much more quickly than
longer clippings). The ideal cutting height will vary with climate,
time of year, and quality of your lawn. We recommend that you
experiment with both the cutting height and ground speed until
you achieve the best cut. 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.

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.

Rear Suspension Adjustment

The shock assembly can be adjusted in two ways to allow the
operator to customize the ride according to operator’s weight
and/or operating conditions. You have the option of adjusting
the spring pre-load and/or the upper mounting position.

Items to consider before adjusting the suspension.

• Less spring pre-load should be used with light weight
operators, which will provide a softer, more cushioned ride.

• More spring pre-load or upper mounting position #2 should
be used with heavy weight operators, or when a rear-mount
grass bagger system is installed, which will provide a stiffer,
more rigid ride.

Loosen the jam nuts and adjust the placement bolt (B) in or out
to properly adjust the lever end spacing.

To Adjust the Handle Height

Remove the mounting hardware and reposition the handle either
up or down from its original position. You will need to readjust
the handle alignment as described above.

To Adjust the Spring Pre-Load:

1. Park machine on a flat, level surface. Disengage the PTO,
stop the engine and engage the parking brake.

2. Raise the rear of the machine and secure with jackstands.
Chock the front wheels to prevent the machine from rolling.

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.

WARNING

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.

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.

Here is a checklist of things to do when storing your unit
temporarily or in between uses:

5. Reinstall the rear drive tires. Torque the lug bolts to 85-95
ft/lbs. (115-129 Nm). Remove the jackstands from under
the machine.

NOTE: Spanner wrench is located under the seat on the
right-hand side of the machine.

To Adjust the Upper Mounting Position:

1. Park machine on a flat, level surface. Disengage the PTO,
stop the engine and engage the parking brake.

2. Raise the rear of the machine and secure with jackstands.
The jackstands must under the bumper. Chock the front
wheels to prevent the machine from rolling.

3. Position the jack under the cross member that ties the
suspension arms together and slowly raise the rear
suspension to relieve the pressure on the upper shock
mounting bolts.

NOTE: This will require small adjustments to the jack’s position.
The shock should move freely on the mounting bolt when the
pressure is relieved.

4. Remove the upper shock mounting hardware and pivot the
shock to the position #2 (see Figure 24). Adjust the jack to
align the shock mounts to the shocks.

• Keep the unit in an area away from where children may
come into contact with it. If there’s any chance of
unauthorized use, remove the spark plug (s) and put in a
safe place. Be sure the spark plug opening is protected
from foreign objects with a suitable cover.

• If the unit can’t be stored on a reasonable level surface,
chock the wheels.

• Clean all grass and dirt from the mower.

Long Term Storage (Longer Than 30 Days)

Before you store your unit for the off-season, read the
Maintenance and Storage instructions in the Safety Rules
section, then perform the following steps:

1. Drain crankcase oil while engine is hot and refill with a grade
of oil that will be required when unit is used again.

2. Prepare the mower deck for storage as follows:
a.) Remove mower deck from the unit.

b.) Clean underside of mower deck.

c.) Coat all bare metal surfaces with paint or light coat of
oil to prevent rusting.

3. Clean external surfaces and engine.

4. Prepare engine for storage. See engine owner’s manual.

5. Clean any dirt or grass from cylinder head cooling fins,
engine housing and air cleaner element.

6. Cover air cleaner and exhaust outlet tightly with plastic or
other waterproof material to keep out moisture, dirt and
insects.

7. Completely grease and oil unit as outlined in the
section.

8. Clean up unit and apply paint or rust preventative to any
areas where paint is chipped or damaged.

9. Be sure the battery is filled to the proper level with water
and is fully charged. Battery life will be increased if it is
removed, put in a cool, dry place and fully charged about
once a month. If battery is left in unit, disconnect the
negative cable.

10. Drain fuel system completely or add a gasoline stabilizer
to the fuel system. If you have chosen to use a fuel stabilizer
and have not drained the fuel system, follow all safety
instructions and storage precautions in this manual to
prevent the possibility of fire from the ignition of gasoline
fumes. Remember, gasoline fumes can travel to distant
sources of ignition and ignite, causing risk of explosion and
fire.

Lubrication

NOTE: Gasoline, if permitted to stand unused for extended
periods (30 days or more), may develop gummy deposits
which can adversely affect the engine carburetor and cause
engine malfunction. To avoid this condition, add a gasoline
stabilizer to the fuel tank and run the engine a few minutes,
or drain all fuel from the unit before placing it in storage.

Starting After Long Term Storage

Before starting the unit after it has been stored for a long period
of time, perform the following steps.

1. Remove any blocks from under the unit.

2. Install the battery if it was removed.

3. Unplug the exhaust outlet and air cleaner.

4. Fill the fuel tank with fresh gasoline. See engine manual for
recommendations.

5. See engine owner’s manual and follow all instructions for
preparing engine after storage.

6. Check crankcase oil level and add proper oil if necessary.
If any condensation has developed during storage, drain
crankcase oil and refill.

7. Inflate tires to proper pressure. Check fluid levels.

8. Start the engine and let it run slowly. DO NOT run at high
speed immediately after starting. Be sure to run engine only
outdoors or in well ventilated area.

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 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 gasoline 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 engine.

manufacturer's application for certification. The warranty
period begins on the date the engine is originally purchased.

1

Two years or for the time period listed in the respective engine or

product warranty statement, whichever is greater.

The warranty on emissions-related parts is as follows:

• 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

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 not be liable to warrant failures of
warranted parts caused by the use of a non exempted
add on or modified part.

3. Consequential Coverage
Coverage shall extend to the failure of any engine
components caused by the failure of any warranted
emissions parts.

4. Claims and Coverage Exclusions
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.

Air Index. Briggs & Stratton makes this information available to
the consumer on our emissions labels. The engine emissions
label will indicate certification information.

The Emissions Durability Period describes the number of
hours of actual running time for which the engine is certified to
be emissions compliant, assuming proper maintenance in
accordance with the Operating & Maintenance Instructions. The
following categories are used:

Moderate:

Engine is 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.

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.

For engines less than 225 cc displacement:

Category C = 125 hours, Category B = 250 hours, Category A
= 500 hours

For engines of 225 cc or more displacement:

Category C = 250 hours, Category B = 500 hours, Category A
= 1000 hours
