Safety Rules & Information

OPERATION

• Never run an engine in an enclosed area.

• Mow only in the daylight or with good artificial light,

keeping away from holes and hidden hazards.

• Never operate with guards not securely in place. Be

sure all interlocks are attached, adjusted properly

and functioning properly.

• Be sure all drives are in neutral and parking brake is

engaged before starting engine. Only start engine

from the operator’s position. Use seat belts if provid-

ed.

• Be sure of your footing while using pedestrian con-

trolled equipment, especially when backing up. Walk,

don't run.

• Do not mow in reverse unless absolutely necessary.

Always look down and behind before and while trav-

eling 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 deflec-

tor in place.

• Never operate with the discharge deflector raised,

removed or altered, unless using a grass catcher.

• Do not change the engine governor setting or over-

speed the engine.

• Stop on level ground, lower implements, disengage

drives, engage parking brake, shut off engine before

leaving the operator’s position for any reason includ-

ing emptying the grass catchers or unclogging the

chute.

• Stop equipment and inspect blades after striking

objects or abnormal vibration occurs. Make neces-

sary repairs before resuming operations.

• Keep hands and feet away from the cutting units.

• Never carry passengers and keep pets and

bystanders away.

• Do not operate the unit while under the influence of

alcohol or drugs.

• Slow down and use caution when making turns and

when changing directions on slopes.

• Never raise deck with the blades running.

• Never leave a running unit unattended. Always disen-

gage the PTO, set parking brake, stop engine, and

remove keys before dismounting. Keep hands and

feet away from the cutting units.

• Turn off the PTO switch to disengage the blades

when not mowing.

• Slow down and use caution when making turns and

crossing roads and sidewalks. Stop blades if not

mowing.

• Use care when loading or unloading the machine

into a trailer or truck.

• Use care when approaching blind corners, shrubs,

trees or other objects that may obscure vision.

SLOPE OPERATION

WARNING

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.

Never operate on slopes greater than 20°

(36.4 percent) which is a rise of 7-1/4 feet (220 cm)

vertically in 20 feet (607 cm) horizontally.

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 ACROSS the slope, never up and down the

face, use caution when changing directions and DO

NOT START OR STOP ON SLOPE.

Do Not

• Mow across the face of slopes; never up and down.

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

• Watch for holes, ruts, or bumps. Uneven terrain

could overturn the unit. Tall grass can hide obsta-

cles.

• 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 embank-

ments. The operator could lose footing or balance or

mower could suddenly turn over if a wheel is over

the edge of a cliff or ditch, or if an edge caves in.

• Do not mow on wet grass. Reduced footing or trac-

tion could cause sliding.

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

the ground.

• Do not mow excessively steep slopes.

• 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.

• Keep all movement on the slopes slow and gradual.

Do not make sudden changes in speed or direction.

• See your authorized dealer for recommendations of

available weights to improve stability.

• Do not use grass catcher on steep slopes.

Features & Controls

D. Parking Brake Handle

SAFETY INTERLOCK

SYSTEM

The parking brake is applied by pushing DOWN on the

parking brake handle until it stops. To release the park-

ing brake, pull UP on the handle until it locks over cen-

ter.

This unit is equipped with safety interlock switches.

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

Test 1 — Engine should NOT crank if:

F. Operator Presence Handles

• PTO switch is engaged, OR

These handles are a major factor in the safety interlock

system of the mower. Both handles are tied together so

depressing one handle depresses both. The operator

must depress the handles in order to disengage the

parking brake and engage the PTO switch.

• Parking brake is not engaged, OR

• Motion control handle is not in the NEUTRAL posi-

tion

Test 2 — Engine SHOULD crank if:

G & H. Throttle / Choke Control

• PTO switch is NOT engaged, AND

• Parking brake is engaged, AND

Pulling the round choke control knob (H) out fully chokes

the engine for cold starts. (A warm engine may not

require choking.) Moving the throttle control (G) fully

towards the right is FULL throttle position. Always oper-

ate the unit at FULL throttle when mowing.

• Motion control handle is in the NEUTRAL position

Test 3 — Engine should SHUT OFF if:

• Operator releases the operator presence handles

with PTO engaged, OR

I. Neutral Return Pedal

• Operator releases the operator presence handles

with parking brake disengaged.

The neutral return pedal provides a hands-free return to

neutral. This is used in conjunction with the Reverse

Speed Control Levers (B) to properly stop the machine.

Test 4 — Blade Brake Check

Mower blades and mower drive belt should come to a

complete stop within seven seconds after electric PTO

switch is turned off (or operator releases the operator

presence handles). If mower drive belt does not stop

within seven seconds, see your dealer.

See the Operating the Dual Drive Walk-Behind Mower

section for steering instructions.

J. Fuel Shut Off Valve (not shown)

The fuel shut off valve is located under the fuel tank.

Turning the handle until it is VERTICAL will allow fuel to

be supplied to the engine. Turning the handle until it is

HORIZONTAL shuts off the fuel supply to the engine.

NOTE: Once the engine has stopped, PTO switch must

be turned off, parking brake must be engaged, and the

motion control handle must be returned to the NEU-

TRAL position 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.

STORAGE

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.

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.

Handle gasoline carefully. It is highly flammable

and careless use could result in serious fire

damage to your person or property.

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.

Drain fuel into an approved container outdoors

away from open flame or sparks.

10. Drain fuel system completely or add a gasoline stabi-

lizer 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

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.

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.

STARTING AFTER LONG TERM

STORAGE

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

period of time, perform the following steps.

CHECKING / ADDING FUEL

To add fuel:

WARNING

Gasoline is highly flammable and must be

handled with care. Never fill the tank when the

engine is still hot from recent operation. Do not

allow open flame, smoking or matches in the area.

Avoid over-filling and wipe up any spills.

1. Remove the fuel cap (see A, Figure 2).

2. Fill the tank to the bottom of the filler neck. This will

allow for fuel expansion.

NOTE: Do not overfill. Refer to your engine manual for

specific fuel recommendations.

Do not remove fuel filter when engine is hot, as

spilled gasoline may ignite. DO NOT spread hose

clamps further than necessary. Ensure clamps

grip hoses firmly over filter after installation.

3. Install and hand tighten the fuel cap.

4. Repeat same process for opposite tank.

FUEL FILTER

The fuel filter (D, Figure 2) is located in the fuel line

between fuel shut off valve and carburetor, near the fuel

pump. If filter is dirty or clogged, replace as follows:

Do not use gasoline containing METHANOL,

gasohol containing more than 10% ethanol,

gasoline additives, premium gasoline, or white

gas because engine/fuel system damage

could result.

1. Shut off the fuel tank selection valve.

2. Disconnect the negative battery cable.

3. Place a container below the filter to catch spilled fuel.

4. Using a pliers, open and slide hose clamps from fuel

filter.

5. Remove hoses from filter.

6. Install new filter in proper flow direction in fuel line.

7. Secure with hose clamps.

8. Reconnect the negative battery cable when finished.

adjusted.

7. Adjust the two front hanger shafts as needed until

the tip of the blade is 2” from the floor and the meas-

urements taken from the top of the deck to the floor

are within 1/16" of each other.

Figure 19. Mowing Height Measurement

8. Once the level of the deck has been adjusted, there

should be no slack in the front hanger shafts. If one

shaft moves, a shim (P/N 20928) is required.

Troubleshooting, Adjustment & Service

Shimming the Hanger Shafts

Once it has been determined that a shim (P/N 20928) is

required, you first must determine which rear hanger

shaft requires the shim.

The shim (A, Figure 20) must be placed in between the

spacer (B, Figure 20) and the retaining collar (C, Figure

20) on the OPPOSITE side from which the front shaft

has movement or slack (see Figure 21).

Once the shim has been assembled in the proper loca-

tion, repeat Step 2 - 8 in the DECK LEVELING

ADJUSTMENT section. This adjustment may need to

be repeated more than once until the proper number of

shims has been installed to obtain the proper cutting

height, equal measurements from side to side and no

TRANSMISSION MAINTENANCE

AND SERVICE

The hydrostatic transmissions are sealed units that

require no maintenance other than the following.

• Keep the grass screen and transmission cooling fins

clear or grass, leaves and debris.

• Keep oil level in the reservoirs (A, Figure 30) at the

“FULL” line (B, Figure 30). Extra oil in the reservoir

will not benefit the machine.

• If it is necessary to add oil to the reservoirs, use SAE

straight 20 or 30 weight motor oil. DO NOT use a

multi-grade oils. Make sure the area around the oil

reservoirs is free from dust, dirt and debris before

opening the reservoirs.

Figure 30. Oil Reservoirs

A. Oil Reservoirs

B. “FULL” Line

• Make sure the oil reservoirs caps are tight.

• Keep water, dirt and debris from entering the oil

reservoirs. A small amount of a contaminant could

damage the transmissions.

Changing Oil & Filters

Make sure transmissions and imme-

diate surrounding areas are free from

dirt and debris before changing the

oil and filters. Cleanliness while per-

forming this operation is extremely

important.

1. Park the machine on a smooth, level surface such as

a concrete floor. Disengage the PTO, engage the

parking brake, turn off the engine, and remove the

ignition key.

Figure 31. Transmission Oil Filter Location

(left-hand side shown)

2. Place a drain pan under each transmission and

remove the filters to drain the oil. See Figure 31.

3. Once oil has drained from transmissions, replace

with new filters (P/N 21068-1), placing a light film on

the seal of the filter before installing. Hand-tighten

filter only.

4. Fill oil reservoirs 3/4 full with SAE straight 20 or 30

weight motor oil.

To Bleed Air From Transmissions

3. Run engine for 15 minutes. Watch the oil level in the

reservoirs. Add oil to the “FULL” line (B, Figure 30)

as necessary.

1. Locate the machine in a secure area, away from

bystanders and preferably facing a wall. Raise the

drive tires off the ground and secure with jackstands.

4. Watch oil levels for the next few days and add oil to

the reservoirs as necessary.

2. Start the engine and adjust throttle control to FULL

(highest setting). See the STARTING THE ENGINE

section for proper starting instructions.

WARNING

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.

To avoid serious injury, perform adjustments only

with engine stopped, key removed and machine

on level ground.

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 belts should come to a

complete stop within seven seconds after electric PTO

switch is turned off.

2. See Figure 32. Note the position of the 3 adjustment

windows (A) in the side of the brake plate and the

nylock adjustment nuts (B).

1. Remove deck guard(s) for checking blade brake stop

time ONLY. NEVER OPERATE the machine without

guard(s) in place.

3. Insert a .012”-.018” (0,30-0,45mm) feeler gauge (C)

through each window, positioning the gauge between

the rotor face and the armature face as shown in

Figure 33.

1. With parking brake engaged and PTO disengage,

start the engine engine.

2. Observe the mower 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.

4. Alternately tighten the adjustment nuts (B, Figure 32)

until the rotor face and armature face just contacts

the gauge.

3. If the mower drive belt does not stop within seven

seconds, perform the PTO Clutch Adjustment. If the

belt still does not stop within seven 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 seven seconds after the electric

PTO switch is turned off.

Jump Starting With Auxiliary (Booster)

Battery

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.

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 34.

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.

Checking Battery Voltage

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.

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.

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.

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.

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 batter-

ies.

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.

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.

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.

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.

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.

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

ing or removing the clamp connections.

4. Carefully attach the clamps to the battery in proper

polarity (usually red to [+] positive and black to [-]

negative).

11. Remove the other cable by disconnecting at the dis-

charged battery first and then disconnect the oppo-

site end from the booster battery.

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.

12. Discard the damp cloths that were placed over the

battery vent caps.

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 spe-

cific gravity occurs over a three hour period.

• 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.

Cutting the grass too short

causes weak, thin grass

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).

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

Always start mowing on a smooth, level area.

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.

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.

deck which cuts and recuts clip-

pings into tiny particles and

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.
