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
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.

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.
C. Ignition Switch
A & B. Forward Speed Control Lever /
Reverse Speed Control Levers
The ignition switch starts and stops the engine, it has
three positions:
These levers control the ground speed of the mower.
OFF
Stops the engine and shuts off the
electrical system.
The center lever (A) control the forward ground speed of
both drive wheels.
RUN
Allows the engine to run and powers the
electrical system.
The left lever controls the steering and reverse ground
speed of the left drive wheel and the right lever controls
the steering and reverse ground speed of the right drive
wheel.

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.

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.

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.

sulfuric acid solution which can cause serious
personal injury or property damage.
(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.
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.
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.
To avoid engine damage, do not disconnect
battery while engine is running. Be sure terminal
connections are tight before starting.

Lawn Care
& 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.

specific lawn will depend
upon several factors,
including the type of grass,
the amount of rainfall, the
prevailing temperature, and
the lawn’s overall condition.
Cutting 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).

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

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.
