excess of 85 dBA at the operator's ear and
can cause hearing loss though extended
periods of exposure.
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
practtces 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
ignition source (such as a furnace, water heater, etc.)
and cause an explosion. Fuel vapor is also toxic to
humans and animals.
4. Never store the unit or fuel container inside where
there is an open flame or pilot light, such as near a
water heater. Allow unit to cool before storing.
SLOPE OPERATION
Slopes are a major factor related to loss-of-controland 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: insufficient tire
grip on the ground, speed too fast, inadequate braking, the
type of machine is unsuitable for its task, lack of awareness
of the ground conditions, incorrect hitching and load
distribution•
. Mow up and down the face of slopes, not across.
• 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. 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.
6. Keep all movement on slopes slow andgradual. Do
not make sudden changes in speed or direction,
which could cause the machine to rollover.
7. Use extra care while operating machines with grass
catchers or other attachments; they can affect the
stability of the unit. Do not use on steeps slopes.
8. Do not try to stabilize the machine by putting your
foot on the ground (ride-on units).
9. Do not mow near drop-offs, ditches, or
embankments. The mower could suddenly turn over if
a wheel is over the edge of a cliff or ditch, or if an
edge caves in.
10. Do not use grass catchers on steep slopes.
11. Do not mow slopes if you cannot back up them.
12. See your authorized dealer/retailer for
recommendations of wheel weights or
counterweights to improve stability.
13. Remove obstacles such as rocks, tree limbs, etc.
14. Use slow speed. Tires may lose traction on slopes
even through the brakes are functioning properly.
15. Do not turn on slopes unless necessary, and then,
turn slowly and gradually uphill, if possible. Never
mow down slopes•
, 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.
Select slow ground speed before driving onto slope.
Use extra caution when operating on slopes with rear-
mounted grass catchers.
Mow up and down the face of slopes, not across. Use
caution when changing directions and DO NOT
START OR STOP ON SLOPE.
CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the unit
and the mowing activity. Never assume that children will
remain where you last saw them.
1. Keep children out of the mowing area and under the
watchful care of another responsible adult.
2. Be alert and turn unit off if children enter the area.
3. Before and during reverse operation, look behind and
down for small children.
4. Never carry children, even with the blade(s) off. They
may fall off and be seriously injured or interfere with
safe unit operation. Children who have been given
rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over
by the machine.
5. i'_ever allow children to operate the unit.
6. Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
EMISSIONS
1. Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth
defects, or other reproductive harm.
2. Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
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 manufacturers recommendations for
weight limit for towed equipment and towing on
slopes. See attaching a trailer under OPERATION.
3. Never allow children or others in or on towed
equipment.
4. On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Do not shift to neutral and coast down hill.
IGNITION SYSTEM
1. This spark ignition system complies with Canadian
ICES-O02.

stopping, driving, and mowing require the
combined use of several controls applied in
specific sequences. To learn what combination
and sequence of controls to use for various
tasks please read the entire section.
_ Ground Speed Levers/
Parking Brake
These levers control the ground speed and parking brake
of the rider. The left lever controls the left rear drive
wheel and the right lever controls the right rear drive
wheel and parking brake.
Pushing the levers out to the side, away from the
operator's lap, locks the parking brake in PARK position
(inset, Figure 1). This is the proper position for starting
the rider. Pulling the levers in across the operator's lap
puts the levers in DRIVE positions.
From DRIVE position, moving a lever forward increases
the FORWARD speed of the associated wheel. Pulling
back on a lever increases the REVERSE speed. The
further a lever is pushed, the faster the drive wheel will
turn.
ReleaseLevers
The engine speed control adjusts engine speed. Always
set the engine speed to FAST for driving and mowing.
Move the engine speed control back to SLOW to

GENERAL OPERATING SAFETY
Before first time operation:
Be sure to read all information in the Safety and
Operation sections before attempting to operate this
rider and mower,
Become familiar with all of the controls and how to stop
the unit.
Drive in an open area without mowing to become
accustomed to driving the unit.
-AWARNING
if you do not understand how a specific control
functions, or have not yet thoroughly read the
CONTROL FUNCTIONS section, do so now.
Do NOT attempt to operate the rider without first
becoming familiar with the location and function
of ALL controls.
9
CHECKS BEFORE STARTING
• Check that the crankcase oil is filled to full mark on
dipstick (see CHECK ENGINE OIL LEVEL in the
Maintenance Section).
Fill the fuel tank with fresh fuel.
FUEL RECOMMENDATIONS
For daily operation: Use only unleaded gasoline with a
pump sticker octane rating of 87 or higher. Gasohol (up
to 10% ethyl alcohol, 90% unleaded gasoline by volume)
is approved as a fuel. Methyl Teriary Butyl Ether (MTBE)
and unleaded gasoline blends (up to a maximum of 15%
MTBE by volume) are approved as a fuel. 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 components and void the
engine warranty. Do not use fuel additives other than
fuel stabilizer.
For storage: CAUTION: Alcohol blended fuels (called
gasohol or using ethanol or methanol) can attract
moisture which leads to separation and formation of
acids during storage. Acidic gas can damage the fuel
system of an engine while in storage.
To avoid engine problems always use fuel stabilizer,
especially before storage of 30 days or longer. Use fresh
fuel next season. See STORAGE instructions for
additional information.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur. To add fuel:
1. Remove the fuel cap (B, Figure 2).
2. Fill the tank. Do not overfill. Leave 2 inches of air
space (5 cm) in the tank for fuel expansion.
3. Install and hand tighten the fuel cap.
, WARNING
Never allow passengers to ride on the unit.
Before leaving the operator's position for any
reason, engage the parking brake, and disengage
the PTO. Never leave the unit unattended (i.e. out
of sight) with the engine running.
To reduce fire hazard, keep the engine, rider and
mower free of grass, leaves and excess grease.
Do not stop or park rider over dry leaves, grass or
combustible materials.

DRiViNG PRACTICE -
BA SIC DRi VING
WARNING: Never operate on slopes greater than 17.6%
(10°). See SLOPE OPERATION in the safety section.
Zero turn riders operate differently from other four-
wheeled vehicles. The drive wheels are also your
steering wheels. If you cannot drive the unit on a hill, you
will not be able to steer the unit on it. Operating zero
turn units on slopes requires extra caution.
The lever controls of the zero turn rider are very
responsive, and learning to gain a smooth and efficient
control of the dder's forward, reverse, and turning
movements will take some practice.
Spend some time going through the following maneuvers
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.
Avoid turf damage! To avoid turf damage, keep both
drive wheels moving while executing turns. Pivoting on
one wheel, or dragging a wheel through a turn will
damage your lawn.
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.
Smooth Travel
The lever controls of the
zero turn rider are
highly responsive.
The BEST method of
handling the ground
speed control levers is in
three steps -- as shown
in Figure 4.
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 back toward
neutral.
Figure 4. Move Control
Levers Gradually
Forward Travel Practice
Gradually move both ground speed control levers evenly
FORWARD from neutral. Slow down and repeat.
Reverse Travel Practice
LOOK DOWN & BEHIND, then gradually move both
ground speed control levers evenly BACK from neutral.
Slow down and repeat.
WARNING
Do not mow in reverse unless absolutely
| necessary. Always look down and behind before
and while traveling in reverse.
Forward Travel
Sit ',,
....i ',,,
,,,L ,,
Figure 5.
Forward Travel
NOTE: Practice backing up for several minutes before
attempting to do so near objects. The rider turns as
sharply in reverse as when going forward, and backing
up straight takes practice,
Reverse Travel
Figure 6.
12
Reverse Travel
Practice Turning Around a Corner
While traveling forward allow one handle to gradually
return back toward neutral. Practice several times before
mowing.
NOTE: To prevent damaging your lawn by pivoting
directly on the tire tread, it is best to keep both wheels
going at least slightly forward.
Practice Turning In Place
To "zero turn" means to turn in place. To turn in place,
gradually move one ground speed control lever forward
from neutral and one lever back from neutral
simultaneously. Repeat several times.
Executing Turns
/ i
Figure 7. Right Turn
ADVANCED DRiViNG
Executing an End-Of-Row Zero
Turn
Your zero turn rider's untque ability to turn in
place allows you to turn around at the end of
a cutting row rather than having to stop and
make a Y-turn before starting a new row.
Turning In Place
Figure 8. Turning in Place
For example, to execute a right end-of row
zero turn:
,
Slow down at the end of the row.
2.
Move the LEFT ground speed control
lever forward slightly while moving the
RIGHT ground speed control lever back to
center and then slightly back from center.
Be sure to keep both wheels moving.
3. Begin mowing forward again.
This technique turns the rider RIGHT 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 rider will be!

STORAGE
Before Storage
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:
Turn the mower blades OFF, set the ground speed
control levers to START / PARK, & remove the key
from the ignition switch.
Check all fluid levels. Check all maintenance items.
Battery life will be increased if it is removed, put in a
cool, dry place and fully charged about once a
month. If the battery is left in the unit, disconnect the
negative cable.
It is important to prevent gum deposits from forming in
the essential fuel system parts such as the carburetor,
fuel filter, fuel line, and fuel tank during storage. Also,
alcohol blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to the
separation and formation of acids during storage. Acidic
gas can damage the fuel system of an engine while in
storage.
To avoid engine problems use fuel stabilizer, especially
before storage of 30 days or longer.
WARNING
Never store the unit (with fuel) in an enclosed,
poorly ventilated structure. Fuel vapors can
travel to an ignition source (such as a furnace,
water heater, etc.) and cause an explosion.
Fuel vapor is also toxic to humans and animals.
After Storage
Before starting the unit after it has been stored:
= Check all fluid levels. Check all maintenance items.
• Fill with FRESH fuel.
After starting, allow the engine to warm before
operating.

,WARNING
To avoid serious injury, perform maintenance on
the rider or mower only when the engine is
stopped and the ground speed levers are set to
PARK.
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 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. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-
engine variability, Given both the wide array of products on which engines are placed and the variety of environmental issues
applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power
equipment (actual "on-site" or net horsepower). This difference is due to a variety of factors including, but not limited to,
accessories (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.
