Safety Rules
& Information
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.

GENERAL OPERATION

WARNING
Never operate on slopes greater than 30 percent
(16.7°) which is a rise of three feet vertically in 10
feet horizontally.
Select slow ground speed before driving onto slope.
Use extra caution when operating on slopes with rearmounted 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.

• 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.
• 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 serious injury.

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
drive on it

Do
• See your authorized dealer for recommendations of
available weights 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. 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.

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 uphill, 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 catcher on steep slopes.

CONTROL FUNCTIONS
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.

A. Ground Speed Control Levers

B. Seat Adjustment Lever

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.

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

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

C. Ignition Switch
The ignition switch starts and stops the engine, it has
three positions:

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

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.

See the Operating the Zero Turn Rider section for steering instructions.

Features & Controls
SAFETY
INTERLOCK SYSTEM

D. Parking Brake Handle
The parking brake is applied by pulling UP on the parking brake handle until it locks over-center. To release the
parking brake, push the handle DOWN.

This unit is equipped with safety interlock switches and
other safety devices. These safety systems are present
for your safety, do not attempt to bypass safety switches, and never tamper with safety devices. Check their
operation regularly.

E. PTO (Power Take Off) Switch
The PTO switch engages and disengages the mower.
Pull UP on the switch to engage, and push DOWN to
disengage.

Operational SAFETY Checks

F & G. Deck Lift Pedal & Cutting Height
Adjustment Pin

Your unit is equipped with a seat switch safety system.
Check the seat switch operation every fall and spring
with the following tests.

These control the cutting height of the mower deck.
Depress the pedal until it locks into the TRANSPORT
position. Place the adjustment pin in the desired cutting
height and release the lift pedal.

Test 1 — Engine should NOT crank if:
• PTO switch is engaged, OR
• Parking brake is not engaged, OR
• Motion control handles are not in the NEUTRAL
position, OR
• Operator is not on the seat.
Test 2 — Engine SHOULD crank if:

H & I. Throttle / Choke Control
Pulling the round choke control knob (I) out fully chokes
the engine for cold starts. (A warm engine may not
require choking.) Moving the throttle control (H) fully forward is FULL throttle position. Always operate the unit
at FULL throttle when mowing.

• PTO switch is NOT engaged, AND
• Parking brake is engaged, AND
• Motion control handles are locked in the NEUTRAL
position, AND
• Operator is on the seat.
Test 3 — Engine should SHUT OFF if:

J. Headlight Switch
Turn the switch ON to light the front headlight.

K. Hour Meter
Measures the time of the PTO being engaged.

• Operator rises off seat with PTO engaged, OR
• Operator rises off seat with parking brake disengaged.
Test 4 — Blade Brake Check

L. Fuel Shut Off Valve
Turning the handle to the desired position determines
which tank will be supplying fuel. With the handle pointing forward, it will draw fuel from the left-hand tank. With
the handle pointed towards the rear, it will draw fuel from
the right-hand fuel tank. With the handle pointing
towards the right, it will shut off fuel flow to the engine.

Mower blades and mower drive belt should come to a
complete stop within five seconds after electric PTO
switch is turned off (or operator rises off seat). If mower
drive belt does not stop within five seconds, see your
dealer.

NOTE: Once the engine has stopped, PTO switch must
be turned off, parking brake must be engaged, and the
motion control handles must be locked in the NEUTRAL
position after the operator returns to the seat in order to
start the engine.

WARNING
If the unit does not pass a safety test, do not
operate it. See your authorized dealer. Under no
circumstance should you attempt to defeat the
purpose of the safety interlock system.

ZERO TURN
DRIVING PRACTICE

Smooth Travel
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 4.

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 move
the levers farther forward.
To slow down smoothly,
slowly move the levers
toward neutral.

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.

Figure 4. Move Control
Levers Gradually

BASIC DRIVING
Forward Travel Practice

Reverse Travel Practice

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

LOOK DOWN & BEHIND, then gradually move both
ground speed control levers evenly BACK 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 Adjustments 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.

Practice Turning Around a Corner

Practice Turning In Place

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

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

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!

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.
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.

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.

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.
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.

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

WARNING

PTO CLUTCH ADJUSTMENT
Check the PTO clutch adjustment after the initial 50 hour
break-in period and then after every 250 hours of operation. Also perform the following procedure if the clutch is
slipping or will not engage, or if a new clutch has been
installed.

To avoid serious injury, perform adjustments only
with engine stopped, key removed and tractor on
level ground.

Blade Brake Check

1. Remove key from ignition switch and disconnect
spark plug wires to prevent the possibility of accidental starting while the PTO is being adjusted.

Mower blades and mower drive belt should come to a
complete stop within five seconds after electric PTO
switch is turned off.

2. See Figure 25. Note the position of the 3 adjustment
windows (A) in the side of the brake plate and the
nylock adjustment nuts (B).

1. With parking brake engaged, PTO disengaged and
an operator in the seat, start the engine engine.

3. Insert a .016”-.018” (0.40-0.45mm) feeler gauge (C)
through each window, positioning the gauge between
the rotor face and the armature face as shown in
Figure 26.

2. Have an assistant observe the mower drive belt
through the open end of the left-hand arbor cover.
Engage the PTO and wait several seconds.
Disengage the PTO and check the amount of time it
takes for the mower drive belt to stop.

4. Alternately tighten the adjustment nuts (B, Figure 25)
until the rotor face and armature face just contacts
the gauge.

3. If the mower drive belt does not stop within five seconds, perform the PTO Clutch Adjustment. If the belt
still does not stop within 5 seconds, see your dealer.

5. Check the windows for an equal amount of tension
when the gauge is inserted and removed, and make
any necessary adjustments by tightening or loosening the adjustment nuts.

NOTE: The actual air gap between the rotor and armature may vary even after performing the adjustment procedure. This is due to dimensional variations on component parts, and is an acceptable condition.
6. Check the mower blade stopping time. The mower
blades and mower drive belt should come to a complete stop within five seconds after the electric PTO
switch is turned off.

Troubleshooting, Adjustment & Service
NEUTRAL ADJUSTMENT
If the tractor “creeps” while the ground speed control
levers are locked in NEUTRAL, than it may be necessary to adjust the control linkage.

NOTE: Perform this adjustment on a hard, level surface
such as a concrete floor.
1. Disengage the PTO, engage the parking brake and
turn off the engine.
2. There are three (3) nuts on the linkage rod. The first
two are to be used together to turn the rod and the
third (towards the rear of the machine) is used to
lock the rod in place. Loosen the third jam nut (B,
Figure 27) and turn the adjustment linkage (A, Figure
27) to adjust. If the machine creeps forward, turn the
linkage CLOCKWISE (while standing at the rear of
the machine, facing forward), if the machine creeps
backward, turn the linkage COUNTER-CLOCKWISE.

B
A

3. Lock the jam nut (B) when neutral is achieved.

NOTE: This adjustment should not be performed while
the machine is running. It may take several attempts to
achieved neutral, depending upon how much the
machine creeps.

NEUTRAL SPRING RETURN
ADJUSTMENT

This adjustment will tailor the “feel” of the control levers
to the operator.
Each of the springs (A, Figure 28) has three adjustment
holes (B, Figure 28). The closer the spring is located to
the neutral return arm’s pivot (D, Figure 28), the less
spring force will be felt by the operator while driving and
will return to neutral slower.

The farther the spring is located from the neutral return
arm’s pivot (D, Figure 28), the more spring force will be
felt by the operator while driving and will return to neutral faster.

1. Park the machine on a flat, level floor and engage
the parking brake. Rear tires must be inflated to 15
psi; front tires to 20 psi.
2. With the deck height adjustment pin in the 4" position, adjust the 5/8” hex nuts on either side of the
front spring rod pivot (see Figure 30) until the rear
lower edge of the cutter deck directly behind the
chain is 3-5/8" from the floor. The front lower edge of
the cutter deck directly in front of the eyebolt should
be 3-1/2" from the floor (4-1/2” for ACP deck). If not,
adjust the front deck hanger eyebolt to correct the
cutting height. Perform this step to both rods.
3. With the deck height adjustments complete and cutting height still set at 4", adjust the deck lift spring to
a compressed length of 14-1/4" (measure spring
only). Adjust the length of the deck lift spring by
tightening or loosening the (2) 5/8” hex nuts that are
closest to the spacer at the front end of the spring
(see Figure 30). After adjustment is made, tighten
these two nuts together. Perform this step to both
springs.

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.

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.
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.

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.

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.

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:

Types of Grass, Climate and Conditions
How and When to Water, Fertilize & Aerate
How High to Mow the Grass
When and How Often to Mow
What Mowing Patterns to Use
Proper Mowing Methods
How to Solve Common Mowing Problems

TYPES OF GRASS, CLIMATE AND
CONDITIONS
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, buffalo
grass, 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

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

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.

TP 600-7000-01-UV-FD

HOW TO WATER 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.

HOW HIGH TO
MOW THE GRASS

Cut less than

1/3

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.

Optimal
cutting point
at less than
1/3 from top
of grass blade

Cutting down to this
area contributes to
thatch problems

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.

1/3

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.

Proper Cutting Height

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.

LC-2

Lawn Care & Mowing Information
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:
l Mow when the grass is between three and five inches
high.
l 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.
l Mow at time of day when the grass is cool and dry.
Late afternoon or early evening often provide these
ideal mowing conditions.
l 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
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.

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.
l Cut long straight strips overlapping slightly.
l Where possible, change patterns occasionally to
eliminate matting, graining or a corrugated appearance.
l For a truly professional cut, mow across the lawn in
one direction, then recut the lawn by mowing perpendicular to the previous cut.

Note: Always operate the engine at full throttle when
mowing.

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.

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.

LC-3

Lawn Care & Mowing Information
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.

slowing down you are mowing too fast, use a slower
ground speed.

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

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.

that is matched to your mowing conditions and preferCONDITIONS
ences.
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.

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:

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 purchase 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.

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 inexpensive 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.
