GENERAL OPERATION

• Read, understand, and follow all instructions in the manual and on
the unit before starting.

• Only allow responsible adults, who are familiar with the instruc­tions, to operate the unit (local regulations can restrict operator
age).

• Clear the area of objects such as rocks, toys, wire, etc., which
could be picked up and thrown by the blade(s).

• Be sure the area is clear of other people before mowing. Stop unit
if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessary. Always look
down and behind before and while travelling in reverse.

• Be aware of the mower discharge direction and do not point it at
anyone. Do not operate the mower without either the entire grass
catcher or the deflector in place.

• Slow down before turning.

• Never leave a running unit unattended. Always disengage the
PTO, set parking brake, stop engine, and remove keys before dis­mounting.

• Turn off the PTO switch to disengage the blades when not mowing.

• Stop engine before removing grass catcher or unclogging chute.

• Mow only in daylight or good artificial light.

• Do not operate the unit while under the influence of alcohol or
drugs.

• Watch for traffic when operating near or crossing roadways.

• Use extra care when loading or unloading the unit into a trailer or
truck.

• Data indicates that operators, age 60 years and above, are
involved in a large percentage of riding mower-related injuries.
These operators should evaluate their ability to operate the riding
mower safely enough to protect themselves and others from injury.

• Keep in mind the operator is responsible for accidents occurring to
other people or property.

• All drivers should seek and obtain professional and practical
instruction.

• Always wear substantial footwear and trousers. Never operate
when barefoot or wearing sandals.

• Before using, always visually check that the blades and blade hard­ware are present, in-tact, and secure. Replace worn or damaged
parts.

• Never operate the machine with defective guards, or without safety
protective devises in place.

• Disengage attachments before: refuelling, removing an attachment,
making adjustments (unless the adjustment can be made from the
operator’s position).

• When the machine is parked, stored, or left unattended, lower the
cutting means unless a positive mechanical lock is used.

• Follow the manufacturer’s recommendation for wheel weights or
counterweights.

SLOPE OPERATION

Slopes are a major factor related to loss-of-control and tip-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 it, do not operate
on it.

Control of a 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 it’s task, lack of awareness of the ground con­ditions, incorrect hitching and load distribution.

Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control
of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment.

This mowing deck is capable of amputating hands and feet and throwing objects.

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

Safety Rules & Information

WARNING

Never operate on slopes greater than 17.6 percent
(10°) which is a rise of 3-1/2 feet (106 cm) vertically in
20 feet (607 cm) horizontally.

When operating on slopes use additional wheel
weights or counterweights. See your dealer to
determine which weights are available and
appropriate for your unit.

Select slow ground speed before driving onto slope.
In addition to front and rear weights, use extra caution
when operating on slopes with rear-mounted grass
catcher.

Mow UP and DOWN the slope, never across the
face, use caution when changing directions and DO
NOT START OR STOP ON SLOPE.

Do

• See your authorized dealer for recommendations of wheel weights
or counterweights to improve stability.

• Mow up and down slopes, not across.

• 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. Tires may lose traction on slopes even through
the brakes are functioning properly. Choose a low gear so that you
will not have to stop or shift 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.

• Always keep unit in gear especially when traveling downhill. When
clutching, release clutch slowly.

Do Not

• Do not start or stop on a slope. If tires lose traction, disengage the
blade(s) and proceed slowly straight down the slope.

• Do not turn on slopes unless necessary, and then, turn slowly and
gradually downhill, if possible.

• 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.

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

• Do not try to stabilize the unit by putting your foot on the ground.

• Do not use grass catchers on steep slopes.

• Do not mow slopes you cannot back up.

• Do not shift to neutral and coast down hill.

Safety Rules

Slope Operation Continued

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. They may fall off and be seriously injured or
interfere with safe unit operation.

• Never allow children to operate the unit.

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

TOWING

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

• 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.

• 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.

TRANSPORTING AND STORAGE

• Always observe safe refueling and fuel handling practices when
refueling the tractor after transportation or storage.

• Always follow the engine manual instructions for storage prepara­tions before storing the tractor for both short and long term periods.

• Always follow the engine manual instructions for proper start-up
procedures when returning the unit to service.

• Never store the unit or fuel container inside where there is an open
flame or pilot light, such as in a water heater. Allow unit to cool
before storing.

EMISSIONS

• Engine exhaust from this product contains chemicals known, in
certain quantities, to cause cancer, birth defects, or other repro­ductive harm.

• Look for the relevant Emissions Durability Period and Air Index
information on the engine emissions label.

WARNING

When transporting this tractor on an open trailer,
make sure unit is facing forward, toward the direction
of travel. If tractor is facing backward, wind lift could
cause damage to the hood.

SERVICE AND MAINTENANCE

• Use extra care in handling gasoline and other fuels. They are flam­mable and vapors are explosive.
a) Use only an approved container.
b) Never remove gas cap or add fuel with the

engine running. Allow engine to cool before refueling. Do not
smoke.

c) Never refuel the unit indoors.

• If fuel is spilled, do not attempt to start the engine but move the
machine away from the area of spillage and avoid creating any
source of ignition until petrol vapors have dissipated.

• Replace all fuel tank caps and fuel container caps securely.

• Never fill containers inside a vehicle or on a truck bed with a plastic
bed liner. Always place containers on the ground away from your
vehicle before filling.

• Remove gas-powered equipment from the truck or trailer and refuel
it on the ground. If this is not possible, then refuel such equipment
on a trailer with a portable container, rather than from a gasoline
dispenser nozzle.

• Keep 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.

• If fuel is spilled on clothing, change clothing immediately.

• Maintain or replace safety and instruction labels as necessary.

• Never run a unit in an enclosed area.

• Keep nuts and bolts, especially blade attachment bolts, tight and
keep equipment in good condition.

• Never tamper with safety devices. Check their proper operation
regularly and make necessary repairs if they are not functioning
properly.

• Keep unit free of grass, leaves, or other debris build-up. Clean up
oil or fuel spillage.

• Stop and inspect the equipment if you strike an object. Repair, if
necessary, before restarting.

• Never make adjustments or repairs with the engine running unless
specified otherwise in the engine manufacturer’s manual.

• Grass catcher components are subject to wear, damage, and dete­rioration, which could expose moving parts or allow objects to be
thrown. Frequently check components and replace with manufac­turer’s recommended parts, when necessary.

• Mower blades are sharp and can cut. Wrap the blade(s) or wear
gloves, and use extra caution when servicing them.

• Check brake operation frequently. Adjust and service as required.

• Use only factory authorized replacement parts when making
repairs.

• Always comply with factory specifications on all settings and
adjustments.

• Only authorized service locations should be utilized for major ser­vice and repair requirements.

• Never attempt to make major repairs on this unit unless you have
been properly trained. Improper service procedures can result in
hazardous operation, equipment damage and voiding of manufac­turer’s warranty.

• On multiple blade mowers, take care as rotating one blade can
cause other blades to rotate.

• Do not change engine governor settings or over-speed the engine.
Operating the engine at excessive speed can increase the hazard
of personal injury.

• Disengage drive attachments, stop the engine, remove the key,
and disconnect the spark plug wire(s) before: clearing attachment
blockages and chutes, performing service work, striking an object,
or if the unit vibrates abnormally. After striking an object, inspect
the machine for damage and make repairs before restarting and
operating the equipment.

• Never place hands near the hydro pump cooling fan when the trac­tor is running. Cooling fan is located on top of the transaxle

Features & Controls
of the Zero Turn Rider

A. Ground Speed Control Levers

These levers control the ground speed of the rider. The
left lever controls the left rear drive wheel and the right
controls the right rear drive wheel.

Moving a lever forward increases the FORWARD speed
of the associated wheel, and pulling back on a lever
increases the REVERSE speed.

Note: The further a lever is moved away from the neutral
position the faster the drive wheel will turn.

B. Top Speed Adjustment Knobs

These knobs independently control the top speed of the
left and right drive wheels, and are used to balance the
maximum forward lever positions. Turn a knob CLOCK­WISE to lower the top speed of a wheel, and COUNTER­CLOCKWISE to increase the top speed of a wheel.

C. Seat Adjustment Lever

The seat can be adjusted forward and back. Move the
lever to the LEFT, position the seat as desired, and
release the lever to lock the seat in position.

D. Ignition Switch

The ignition switch starts and stops the engine, it has
three positions:

OFF Stops the engine and shuts off the

electrical system.

RUN Allows the engine to run and powers the

electrical system.

START Cranks the engine for starting.

NOTE: Never leave the ignition switch in the RUN posi­tion with the engine stopped–this drains the battery.

CONTROL FUNCTIONS

Please take a moment and familiarize yourself with the name, location, and function of these controls so that

you will better understand the safety and operating instructions provided in this manual.
The information below briefly describes the function of individual controls. Starting, 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 see the OPERATION section.

PUSHING THE RIDER BY HAND

1. Disengage the PTO, engage the parking brake, turn
the ignition OFF, and remove the key.

2. Disengage the transmissions by moving both release
levers from engaged position(A, Figure 6) to released
position (B). The release levers are located in the
back of the unit between the rear weights (see Figure

4). BOTH release levers must be pulled fully rear-

ward and down to push the rider by hand.

NOTE: To drive the rider BOTH release levers must be moved
completely forward to engage the transmissions.

DO NOT TOW RIDER

Towing the unit will cause transmission damage.
Do not use another vehicle to push or pull this unit.

STOPPING THE RIDER

1. Returning the ground speed control levers (A, Figure 3)
to the middle positions will stop rider movement. For

emergency stopping depress the clutch/brake
pedal (see F, Figures 4-5).

2. Disengage the PTO by pushing down on the PTO
switch (See G, Figures 4-5).

3. Set engine throttle control (H, Figures 4-5) to mid­throttle position and turn the ignition key to OFF.

Operating the Zero Turn Rider

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.

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

RESPONSIVE

.

The BEST method of
handling the ground
speed control levers is in
three steps — as shown
in Figure 7.

FIRST place the palms of
your hands onto the
levers as shown.

SECOND, to go forward
gradually push the levers
toward the console with
your palms.

THIRD, to speed up
move the levers farther
forward. To slow down
smoothly, loosen your
grip on the console and
allow the levers to return
toward neutral.

Figure 8. Forward Travel

Figure 9. Reverse Travel

Figure 7. Move Control

Levers Gradually.

Forward 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 Top
Speed Adjustment Knobs in the Adjustments section
near the back of this manual.

Reverse Travel Practice

LOOK DOWN & BEHIND, then gradually move both
ground speed control levers evenly BACK from neutral.
Slow down and repeat.

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.

WARNING

Make certain the area of operation, and especially
the direction of travel is clear of objects, people
and animals.

Always look DOWN AND BEHIND before backing!

Operating the Zero Turn Rider

Figure 11. Turning in Place

Figure 10. Turning Around a Corner

Practice Turning Around a Corner

While traveling forward allow one handle to gradually
return back toward neutral. Repeat several times.

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

Practice Turning In Place

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.

ADVANCED DRIVING

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 right end-of row
Zero Turn:

1. 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.

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 Zero Turn will be!

Operating the Zero Turn Rider

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.

STORAGE

Temporary Storage (30 Days Or Less)

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.

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

• 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 Normal
Care 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 Simplicity 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.

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 Simplicity
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.

Leveling The Mower

If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Tire pressure should be as follows:

• Front: 20 psi (138 kPa) • Rear: 10 psi (69 kPa)

Side to Side Leveling - All Models

1. With the mower installed, place the rider on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.

2. Check for bent blades and replace if necessary.

3. Place the mower in high-cut position. Arrange the
mower blades so that they are pointing from side-to­side (Figure 31).

4. See Figure 32. Measure the distance between the
outside tips of each blade and the ground. If there is
more than 1/8" (3mm) difference between the mea­surements on each side, proceed to step 5. If the dif­ference is 1/8" (3mm) or less, proceed to Front TO
Back Leveling.

5. See Figure 32. Loosen the outside nut (A) and tap­tite screw (C), then turn the eccentric nut (B) to raise
or lower the left side of the deck. When the mower
deck is level, hold the eccentric nut while tightening
the outside nut. Tighten the taptite screw (C).

BATTERY SERVICE

Checking Battery Voltage

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.

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 dealer.

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 attach­ing or removing the clamp connections.

4. Carefully attach the clamps to the battery in proper
polarity (usually red to [+] positive and black to [-]
negative).

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.

WARNING

Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.

WARNING

Do not attempt to charge a frozen battery. Allow
the battery to warm to 60° F (15.5° C) before
placing on charger.

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.

JUMP STARTING WITH AUXILIARY
(BOOSTER) BATTERY

Jump starting is not recommended. However, if it must
be done, follow these directions. Both booster and dis­charged batteries should be treated carefully when using
jumper cables. Follow the steps below EXACTLY, being
careful not to cause sparks. Refer to Figure 42 .

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.

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.

8. Start the engine of the vehicle 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 seldom starts the engine unless some mechani­cal adjustment is made.

10. 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.

12. Discard the damp cloths that were placed over the
battery vent caps.

Troubleshooting, Adjustment & Service

29

WARNING

Any procedure other than the preceding could
result in:

(1) personal injury caused by electrolyte

squirting out the battery vents,

(2) personal injury or property damage due to

battery explosion,

(3) damage to the charging system of the

booster vehicle or of the immobilized
vehicle.

Do not attempt to jump start a vehicle having a
frozen battery because the battery may rupture or
explode. If a frozen battery is suspected, examine
all fill vents on the battery. If ice can be seen or if
the electrolyte fluid cannot be seen, do not
attempt to start with jumper cables as long as the
battery remains frozen.

WARNING

For your personal safety, use extreme care when
jump starting. Never expose battery to open flame
or electric spark – battery action generates
hydrogen gas which is flammable and explosive.
Do not allow battery acid to contact skin, eyes,
fabrics, or painted surfaces. Batteries contain a
sulfuric acid solution which can cause serious
personal injury or property damage.

When removing or installing battery cables, dis­connect the negative cable FIRST and reconnect
it LAST. If not done in this order, the positive ter­minal can be shorted to the frame by a tool.

To avoid engine damage, do not disconnect bat­tery while engine is running. Be sure terminal
connections are tight before starting.

A variety of grasses are commonly grown in household
lawns, but two main groups known as cool-season
grasses (varieties of bluegrass, ryegrass, and fescue),
and warm-season grasses (typically bermuda, buffalo­grass, and zoysia varieties) are the most common.

The cool-season grasses are better suited to cooler cli­mates, and do not endure hot and dry weather as well as
warm-season grasses, but conversely, the warm-season
grasses do not grow as well in cooler climates. Most resi­dential lawns are typically seeded with a mixture of these
grasses. (A local nursery or lawn center may help you to
identify what kind of grass your lawn contains from a
sample.)

Knowing your climate and conditions is also important to
proper lawn care. Drier climates or conditions will require
additional watering, while wetter climates may require
more frequent mowing.

HOW AND WHEN TO WATER,
FERTILIZE & AERATE

Every lawn’s watering needs are unique and are depen­dent upon the type of grass and soil, the amount of local
rainfall, and other conditions. Most lawns are watered
too often, but with too little water. However too much
water can allow development of diseases with your lawn.

It is best to water the lawn only when necessary, and
then to water it slowly, evenly, and deeply—imitating
a slow, soaking rain.

WHEN TO WATER YOUR LAWN

When the lawn begins to wilt, the grass’s color dulls, or
footprints stay compressed for more than a few seconds,
the lawn is beginning to dry out, and needs additional
moisture. The best time to water is early morning to allow
the water to soak deeply into the lawn and reduce the
amount that evaporates in the hot afternoon sun.

HOW TO WATER YOUR LAWN

The best method of watering a lawn is to imitate a slow,
soaking rain, applying about 1 inch of water. A method
of verifying the amount that you have watered, is to place
several empty tin cans (low shallow cans work best) in
various spots around the lawn, and check the depth of
water in the can during the watering process.

HOW TO FERTILIZE YOUR LAWN

Fertilizing with a slow-release fertilizer provides missing
nutrients which help create slow, even growth. While
opinions vary on the need for fertilizing, when and how
much to fertilize will be more a factor of the condition of
the lawn and soil than any routine. Remember that over­fertilizing can cause harm, and that most fertilizing
should be applied in the spring so that it will release into
the lawn through the summer. For more information,
check with a local nursery or lawn care specialist, and
read and follow the fertilizer manufacturer’s instructions.

AERATING YOUR LAWN

Consider aerating your lawn in spring. Using an aerator
to remove cores of soil from the lawn increases the
speed of clipping decomposition and encourages deeper
root growth by opening up the soil and permitting greater
movement of water, fertilizer and air.

GENERAL INFORMATION

Proper mowing is an important part of maintaining your
lawn in the best possible condition. A healthy and well
maintained lawn is better able to resist drought, weeds,
and other stresses. But too much maintenance is as
detrimental to your lawn as neglect. Proper care for your
lawn involves more than just “cutting the grass.” To have
a healthy lawn, you need to know:

HOW HIGH TO
MOW THE 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 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.

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).

NOTE: We cover some specific mowing instructions for
mulching and broadcasting later in this Lawn Care section.

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.

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

Lawn Care & Mowing Information

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.

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).

WHAT MOWING PATTERNS TO USE

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 recut the lawn by mowing perpen-

dicular to the previous cut.

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.

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.

MOWING METHODS

Proper 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.

Part No. 1686609
(Contains 8 shredders)

Proper Mulching

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 by­products 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 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 BROADCASTING

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 1/2 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.

LEAF SHREDDING (USE WITH OPTIONAL MULCHER KIT)

Simplicity’s patented Shredder Blades virtually eliminate
raking leaves. Up to 512 cutting edges pulverize leaves
into tiny particles, which quickly and naturally decom­pose into food for your lawn. The Shredder Blades must
be removed when you mulch grass clippings.

TIPS On Dealing With Clippings

Clippings are beneficial to your lawn. A common mis­conception about clippings is that they automatically
lead to thatch—this is untrue. Short clippings produced
by broadcasting and clippings produced by mulching
methods actually contribute to a healthy lawn
because they:

✘ Reduce the evaporation of water from your lawn.
✘ Provide a cushioning layer to reduce lawn wear.
✘ Moderate soil temperature.
✘ Clippings act as a safe, non-polluting and inexpen-

sive fertilizer that nourishes your lawn. Fresh cut
grass blades are 85% water, and are a rich source
of nitrogen which is essential to lush growth. And
one garbage bag of clippings contains about 1/4 lb.
of usable organic nitrogen.

COMPOSTING

The best way to recycle excess clippings and leave your
lawn looking immaculate is to collect them with an effi­cient collection system and deposit them in a compost
pile. A compost pile is a collection of grass, leaves, and
other organic wastes which—when properly tended—
decompose into an odorless, topsoil material. This
material, in turn, acts as an inexpensive fertilizer for your
lawn and garden.

How to start a healthy compost pile:

1 Build a bin using bricks, fencing, cement blocks, etc. or pur-

chase a prefabricated bin from a garden store. The bin
should also have venting on each side and from the bottom
to the top.

2 Fill the bin with alternating layers of yard waste. Follow this

recipe:
First layer: 3-4 inches of chopped brush or other coarse

material.
Second layer: 6-8 inches of mixed leaves, grass clippings,

sawdust, etc. Materials should be "sponge damp."
Third layer: 1 inch of soil to add micro-organisms that help

break down organic matter.

Fourth layer: 1-2 inches of manure to provide the nitrogen
needed by micro-organisms.

Keep adding layers until the bin is almost full. Top off with
a 4-6 inch layer of straw and scoop out a "basin" to catch
rain water.

3 Four or five days later the pile will reach temperatures of

140-160 degrees. At this time you'll notice it settling, a
good sign your compost is working properly.

4 After 5-6 weeks, fork materials into a new pile, turning the

outside of the old heap into the center of the new one. Add
water if necessary. The compost should be ready to use
within three to four months when dark brown, crumbly, and
earthy-smelling.
