Safety Rules & Information

SLOPE OPERATION

CHILDREN

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

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 chil-

back up the slope or if you feel uneasy on it, do not drive dren will remain where you last saw them.

on it.

• Keep children out of the mowing area and under the

watchful care of another responsible adult.

WARNING

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

Never operate on slopes greater than 30 percent

(16.7°) which is a rise of three feet vertically in 10

feet horizontally. In the forward direction, this

machine will climb a slope too steep to mow

safely.

• Before and during reverse operation, look behind and

down for small children.

• Never carry children. They may fall off and be seri-

ously injured or interfere with safe unit operation.

• Never allow children to operate the unit.

• Select slow ground speed before driving onto slope.

In addition to front and rear weights, use extra cau-

tion when operating on slopes with rear-mounted

grass catcher.

• Use extra care when approaching blind corners,

shrubs, trees, or other objects that may obscure

vision.

• Watch for any changes in the terrain such as ditches,

holes, rocks, dips and rises, which change the oper-

ating angle of the machine.

TRANSPORTING AND STORAGE

• Always observe safe refueling and fuel handling

practices when refueling the unit after transportation

or storage.

• Carefully follow the “Do’s” and “Dont’s” listed below.

• Always follow the engine manual instructions for

storage preparations before storing the unit for both

short and long term periods.

• See your authorized dealer for recommendations of

available weights to improve stability.

• Always follow the engine manual instructions for

proper start-up procedures when returning the unit to

service.

• 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.

• 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.

• Use slow speed. Choose a slow speed so that you

will not have to stop or change speed while on the

slope.

• Use extra care with grass catchers or other attach-

ments. These can change the stability of the unit.

SERVICE AND MAINTENANCE

• Use extra care when handling gasoline and other

fuels. They are flammable and vapors are explosive.

• Keep all movement on the slopes slow and gradual.

Do not make sudden changes in speed or direction.

a) Use only an approved container.

Do Not

b) Never remove fuel cap or add fuel with the engine

running. Allow engine to cool before refueling. Do

not smoke.

• 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.

c) Never refuel the unit indoors.

• Never run a unit in an enclosed area.

• Do not mow near drop-offs, ditches, or embank-

ments. The mower could suddenly turn over if a

wheel is over the edge of a cliff or ditch, or if an edge

caves in.

• 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.

• Do not mow on wet grass. Reduced traction could

cause sliding.

Features & Controls

of the Zero Turn Rider

Please take a moment and familiarize yourself with

the name, location, and function of the following.

This will enable you to understand the safety and oper-

ating instructions provided in this manual.

Figure 1. CONTROL FUNCTIONS

The information below briefly describes the function of the individual controls. Starting, stopping, driving, and mow-

ing 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

C. Ignition Switch

These levers control the ground speed of the rider. The

left lever controls the left rear drive wheel and the right

lever controls the right rear drive wheel.

The ignition switch starts and stops the engine, it has

three positions:

OFF

Stops the engine and shuts off the

electrical system.

Moving a lever forward increases the FORWARD speed

of the associated wheel, and pulling back on a lever

increases the REVERSE speed.

RUN

Allows the engine to run and powers the

electrical system.

Note: The further a lever is moved away from the neutral

position the faster the drive wheel will turn.

START Cranks the engine for starting.

NOTE: Never leave the ignition switch in the RUN posi-

tion with the engine stopped–this drains the battery.

See the Operating the Zero Turn Rider section, page 8,

for steering instructions.

D. Parking Brake Handle

B. Seat Adjustment Lever

The parking brake is applied by pulling UP on the park-

ing brake handle until it locks over-center. To release the

parking brake, push the handle DOWN.

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.

Features & Controls

E. PTO (Power Take Off) Switch

SAFETY

INTERLOCK SYSTEM

The PTO switch engages and disengages the mower.

Pull UP on the switch to engage the mower, and push

DOWN to disengage the mower.

This unit is equipped with safety interlock switches and

other safety devices. These safety systems are present

for your well being, do not attempt to bypass safety

switches, and never tamper with safety devices. Check

their operation regularly.

F & G. Deck Lift Pedal & Cutting Height

Adjustment Pin

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.

Operational SAFETY Checks

Your unit is equipped with a seat switch safety system.

Check the seat switch operation every fall and spring

with the following tests.

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 for-

ward is FULL throttle position. Always operate the unit

at FULL throttle when mowing.

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

J. Hour Meter

Measures the time of the PTO being engaged.

• Operator is not on the seat.

Test 2 — Engine SHOULD crank if:

K. Voltmeter

Measures the battery voltage.

• PTO switch is NOT engaged, AND

• Parking brake is engaged, AND

L. Water Temperature Gauge (IS4000Z/D31 only)

Measures the engine coolant temperature.

• Motion control handles are locked in the NEUTRAL

position, AND

M. Indicator Lights & Warning Buzzer

• Operator is on the seat.

The indicator lights will illuminate and buzzer will sound

when the ignition switch is in the “ON” position before

cranking the engine. After the engine is running, the

indicator lights will illuminate and the buzzer will sound

when there is either low oil pressure or high coolant

temperature.

Test 3 — Engine should SHUT OFF if:

• Operator rises off seat with PTO engaged, OR

• Operator rises off seat with parking brake disen-

gaged, OR

• Operator moves the control levers out of the neutral

position with the parking brake engaged.

N. Fuel Tank Selection/Shut Off Valve

Test 4 — Blade Brake Check

Turning the handle to the desired position determines

which tank will be supplying fuel. With the handle point-

ing towards the left, it will draw fuel from the left-hand

tank. With the handle pointed towards the right, it will

draw fuel from the right-hand fuel tank. With the handle

pointing towards the operator, it will shut off fuel flow to

the engine.

Mower blades and mower drive belt should come to a

complete stop within seven seconds after electric PTO

switch is turned off (or operator rises off seat). If mower

drive belt does not stop within seven 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.

O. Left Tank Selection Valve

Turning the handle to the desired position determines

which section of the left-hand tank will be supplying fuel.

With the handle pointing towards the right, it will draw

fuel from the primary section of the fuel tank. With the

handle pointing towards the left, it will draw from the

reserve section of the tank. With the handle pointing

towards the operator, it will shut off fuel flow to the tank

selection shut off valve.

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.

Operating the Zero Turn Rider

Smooth Travel

ZERO TURN

The lever controls of the

Zero Turn rider are

RESPONSIVE .

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.

The BEST method of

handling the ground

speed control levers is in

three steps — as shown

in Figure 3.

Spending some time going through the maneuvers

shown and becoming familiar with how the unit acceler-

ates, 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.

We suggest you begin with the Smooth Travel procedure

to the right, and then advance through the forward,

reverse, and turning maneuvers.

THIRD, to speed up move

the levers farther forward.

To slow down smoothly,

slowly move the levers

toward neutral.

You must release the parking brake prior to moving the

control levers inward.

Figure 3. 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 neces-

sary, 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.

Operating the Zero Turn Rider

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 RIGHT ground speed control

lever forward slightly while moving the

LEFT ground speed control lever back to

center and then slightly back from center.

3. Begin mowing forward again.

This technique turns the rider LEFT and

slightly overlaps the row just cut —eliminating

the need to back up and re-cut missed grass.

As you become more familiar and experi-

enced with operating the Zero Turn rider, you

Operating the Zero Turn Rider

11. Drain fuel system completely or add a gasoline stabiliz-

er 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 trav-

el to distant sources of ignition and ignite, causing risk

of explosion and fire.

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.

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.

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 unau-

thorized 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.

WARNING

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

chock the wheels.

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.

• Clean all grass and dirt from the mower.

• If temperature is expected to drop below 35 degrees,

refer to Long Term Storage, Item 2.

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:

Handle gasoline carefully. It is highly flammable

and careless use could result in serious fire

damage to your person or property.

1. Drain crankcase oil while engine is hot and refill with a

grade of oil that will be required when unit is used

again.

Drain fuel outdoors into an approved container

and away from open flame or sparks.

2. Use an Antifreeze tester to check the cooling system’s

level of protection. Read the instructions on the

Antifreeze container for the appropriate ratio of water to

Antifreeze for your geographical area.

STARTING AFTER

LONG TERM STORAGE

Before starting the unit after it has been stored for a long

period of time, perform the following steps.

3. Prepare the mower deck for storage as follows:

a. Remove mower deck from the unit.

b. Clean underside of mower deck.

1. Remove any blocks from under the unit.

2. Install the battery if it was removed.

3. Unplug the exhaust outlet and air cleaner.

c. Coat all bare metal surfaces with paint or light coat of

oil to prevent rusting.

4. Clean external surfaces and engine.

4. Fill the fuel tank with fresh gasoline. See engine manu-

al for recommendations.

5. Prepare engine for storage. See engine owner’s

manual.

5. See engine owner’s manual and follow all instructions

for preparing engine after storage.

6. Clean any dirt or grass from cylinder head cooling fins,

engine housing and air cleaner element.

6. Check crankcase oil level and add proper oil if neces-

sary. If any condensation has developed during stor-

age, drain crankcase oil and refill.

7. Cover air cleaner and exhaust outlet tightly with plastic

or other waterproof material to keep out moisture, dirt

and insects.

7. Check coolant level, refer to “Check Antifreeze Level” on

page 16.

8. Completely grease and oil unit as outlined in the

Regular Maintenance section.

8. Check Hydraulic oil level, refer to “Check Hydraulic Oil

Level” section on page 15.

9. Clean up unit and apply paint or rust preventative to any

areas where paint is chipped or damaged.

9. Inflate tires to proper pressure.

10. 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. 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

SUSPENSION HEIGHT ADJUSTMENT

If the rider tilts either side-to-side or front-to-rear, this

adjustment will level the frame with the ground.

Although this adjustment may not be necessary, it may

be required if additional weight (ie. a grass catcher) is

added to the frame or a drive tire is replaced.

NOTE: Perform this adjustment on a hard, level surface

such as a concrete floor. Making this adjustment will

affect the mower cutting height. For fine cutting height

adjustment, see Mower Deck Leveling Adjustment.

To level the frame, first measure the frame height:

Figure 29. Front Frame Measurement

1. The measurement to the top side of the front frame

rails, just behind the springs and shocks should be

20-5/8” (52,4cm) for each side (see arrow in Figure

29).

2. The measurement to the top of the rear frame rails,

at the widest point on the frame behind the drive

tires should be 21-3/8” (54,3cm) for each side (see

arrow in Figure 30).

3. Loosen the jam nuts and adjust the square-head

allen screw located above each spring.

4. After adjusting all four (4) springs, recheck the meas-

urements and adjust if necessary.

PTO CLUTCH ADJUSTMENT

WARNING

To avoid serious injury, perform adjustments only

with engine stopped, key removed and tractor on

level ground.

Check the PTO clutch adjustment after the initial 50 hour

break-in period and then after every 250 hours of opera-

tion. Also perform the following procedure if the clutch is

slipping or will not engage, or if a new clutch has been

installed.

Blade Brake Check

1. Remove key from ignition switch and disconnect

spark plug wires to prevent the possibility of acciden-

tal starting while the PTO is being adjusted.

Mower blades and mower drive belt should come to a

complete stop within five (5) seconds after electric PTO

switch is turned off.

2. See Figure 35. 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.

2. Look down through the gap between the left side of

the floor and frame rail and observe the PTO drive

belt. 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.

3. Insert a .016” - .018” (0,40mm - 0,45mm) feeler

gauge (C) through each window, positioning the

gauge between the rotor face and the armature face

as shown in Figure 36.

4. Alternately tighten the adjustment nuts (B, Figure 35)

until the rotor face and armature face just contacts

the gauge.

3. If the mower drive belt does not stop within five (5)

seconds, perform the PTO Clutch Adjustment. If the

belt still does not stop within five (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 loosen-

ing the adjustment nuts.

NOTE: The actual air gap between the rotor and arma-

ture may vary even after performing the adjustment pro-

cedure. This is due to dimensional variations on compo-

nent parts, and is an acceptable condition.

6. Check the mower blade stopping time. The mower

blades and mower drive belt should come to a com-

plete stop within five (5) seconds after the electric

PTO switch is turned off.

6. Charge the battery until fully charged (until the spe-

cific 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.

BATTERY SERVICE

WARNING

Keep open flames and sparks away from the

battery; the gasses coming from it are highly

explosive. Ventilate the battery well during

charging.

Checking Battery Voltage

JUMP STARTING WITH AUXILIARY

(BOOSTER) BATTERY

A voltmeter can be used to determine condition of bat-

tery. When engine is off, the voltmeter shows battery

voltage, which should be 12 volts. When engine is run-

ning, the voltmeter shows voltage of charging circuit

which normally is 13 to 14 volts.

Jump starting is not recommended. However, if it must

be done, follow these directions. Both booster and dis-

charged batteries should be treated carefully when using

jumper cables. Follow the steps below EXACTLY, being

careful not to cause sparks. Refer to Figure 44.

A dead battery or one too weak to start the engine may

not mean the battery needs to be replaced. For exam-

ple, 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.

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 batter-

ies 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.

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.

4. Connect positive (+) cable to positive post of dis-

charged battery (wired to starter or solenoid).

5. Connect the other end of same cable to same post

marked positive (+) on booster battery.

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.

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 bat-

tery. Wait a few minutes, then attempt to start the

engine of the vehicle with the discharged battery.

3. Always unplug or turn the charger off before attach-

ing or removing the clamp connections.

9. If the vehicle does not start after cranking for thirty

seconds, STOP PROCEDURE. More than thirty sec-

onds seldom starts the engine unless some mechan-

ical adjustment is made.

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 tempera-

ture 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.

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 dis-

charged battery first and then disconnect the oppo-

site end from the booster battery.

12. Discard the damp cloths that were placed over the

battery vent caps.

When removing or installing battery cables, dis-

connect the negative cable FIRST and reconnect

it LAST. If not done in this order, the positive ter-

minal can be shorted to the frame by a tool.

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

& Mowing Information

• 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

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:

• 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 cli-

mates, 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 resi-

dential 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.)

HOW TO WATER YOUR LAWN

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.

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 AND WHEN TO WATER,

FERTILIZE & AERATE

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 over-

fertilizing 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.

Every lawn’s watering needs are unique and are depen-

dent 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

AERATING 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.

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.

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).

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 appear-

ance.

l For a truly professional cut, mow across the lawn in

one direction, then recut the lawn by mowing perpen-

dicular to the previous cut.

Note: Always operate the engine at full throttle when

mowing.

If you hear the engine slowing down, you are mowing too

fast—using a slower ground speed will improve the cut-

ting 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.

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.

Lawn Care & Mowing Information

MOWING METHODS

Proper Broadcast Mowing

Broadcasting, or side-discharging, disperses fine clip-

pings 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 cut-

ting efficiency of the blades and prevents many common

cutting problems.

slowing down you are mowing too fast, use a slower

ground speed.

HOW MUCH GRASS TO CUT OFF WHEN BROADCASTING

ALWAYS use an appropriate ground speed for the thick-

ness 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.

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 prefer-

ences.

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 horse-

power than broadcasting, using a slower ground speed is

vitally important for proper mulching operation.

Lawn Care & Mowing Information

• Reduce the evaporation of water from your lawn.

• Provide a cushioning layer to reduce lawn wear.

• Moderate soil temperature.

TIPS On Dealing With Clippings

Clippings are beneficial to your lawn. A common mis-

conception 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:

• 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 effi-

cient 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.
