STEERING LAWN TRACTOR!
All WHEEL
Your NOMA PERFORMANCE
lawn tractor is equipped with All Wheel
Steering. This patented system delivers the increased maneuverability
that's essential for cutting a lawn fast and more efficiently. By controlling
both the front and rear wheels, All Wheel Steering creates a center of
turn that is closer to the mowing deck. The result is a tight 13.5-inch
mowing radius that allows you to cut around trees. You can also make
sharp turns without backing up, mow difficult to cut areas, and maneuver
for close trimming. With All Wheel Steering, you spend much less time
mowing your lawn and much more time pursuing your leisure time
activities.

SAFE MOWING
Each person that operates power equipment must learn to use correct and safe
mowing procedures. To help you learn,
carefullyreadthe following pages. Most
of the time the operator was not correctly
shown or did not read the instructions on
the unltor intheOwner's/Operator's Manual
before using the unit. Also, some operatots do not have enough experience. The
result is unsafe use, endangering the operator, bystanders and the equipment. Another result can be a poor appearance of
the area mowed.
Read this book. Read the instructions on
the unit. Operate the mower according to
the Safe Mowing Guide. Follow all safety
rules, cautions or warnings in thisbeck and
on the unit. Make sure anyone that uses
the unit reads the instructions and is told
how to safely operate the mower.
gency, how fast you can stop the blade is
important. Learn howto control the mower
at all times.
Many engines are started by hand. When
you use a pull start or rope start, place your
feet apart and away from the blade(s).
Hold the rope handle tight. Never wrap the
rope around you r arm or fingers for a "Better grip". To start the engine, follow the
instructions on the mower, inthis book and
in the engine operating instructions.
For electric start engines, sit in the seat to
start the engine. The battery can be dangerous.
Follow the instructions on the
battery, the acid container, and in this book
when working with the battery. Even small
batteries have enough voltage to cause an
injury. Always be careful.
The mower is designed to be operated by
one person. Never let another person ride
with you on the unit or on any accessories.
A passenger will make the unit harder to
control, block the visibility or distract the
operator and is dangerous to the operator,
the passenger and the equipment. Without
a passenger seat, the passenger can fall
fromthe mower orcontact dangerous parts.
A mower is not a toy for showing off or for
giving rides.
The mower will give you good service and
durability, ifoperated in normal conditions.
If the mower is not correctly serviced or is
used where the terrain is rough or unsuitable, product performance and safety will
be decreased.
Correct clothing is an important part of safe
mowing. Safety glasses will protect the
eyes from objectsdischarged bythe mower.
Safety shoes with steel plates can protect
a foct from injury bytheblade. For prctection from objects discharged from the
mower, wear clothing that will cover the
arms and legs.
Before you start cutting the grass, practice
using the mower in a large open and level
area. Learn the location of the controls on
the mower.
Know the purpose of the
controls and how they work. In an emer-
GUIDE
The blade of power mower rot_es very
fast. It can discharge rocks and other
objects over a long distance which can be
dangerous. The force of the objects can
break windows, cause injuries or even put
an eye out. Most of the time the injury is to
a person, like a child. Keep every person
completely away from the area to be
mowed. Make sure the grass is not discharged toward anyone. Planning your
mowing pattern has a double advantage. It
can decrease the possibility of an injury
and make the clean up after mowing easier.
Check the terrain of the area to be mowed.
Never cut awet lawn. Wet grasscancause
an accident, affect mower performance
and can cause problems with future lawn
growth and appearance.
Wet grass is
slippery and can cause the mower to slip.
Someone can get injured by touching the
blade(s). Wet grass tends to clog the
mower, causing poor discharge. Cut wet
grass will collect on the lawn, retarding the
growth of the grass.
Also, getting the
mower wet will cause parts to rust and
decrease the life of the unit.
When you look over the lawn, remember
obstacles that cannot be removed, like
pipes, stumps or rocks. Keep away from
these obstacles that can cause damage to
the mower or injury to the operator or a
person near the mower. Clear the area of
rocks, toys, wire or other loose objects.
These ffems can damage the mower or can
be discharged by the mower blade.
7
Mow inpattern that will keep you away from
dangerous areas. Checkthe distance you
need to stop and the distance avairable to
turn. Slopes and rough terrain must be
mowed carefully and some areas must not
be mowed at all. With riding mowers, mow
up and down the hill When you must mow
rough terrain or on slopes, never change
directions or change speeds and stop in
these areas only in and emergency.
Before you ride up or down a slope, try to
back straight up the slope. Do not ride up
or down a slope that is too steep to back
straight up. See the "Guide" in the back of
this Owner's/Operator's Manual to check
any slopes.
SAFE MOWING
Before you start cutting, make sure the
mowerwas completely assembled according to the Owner's/Operator's Manual. If
the mower was completely assembled at
the store, you must still check the mower
according to the assembly instructions.
Make sure the mower is correctly assembled and that all fasteners are tight.
Make sure the engine has the correct
amount of oil. Check these items often
during the life of the mower.
Your mower has a gasoline engine. Gasoline is a dangerous fuel. Keep gasoline
only in an approved safety gasoline container, Do not keep large amounts of
gasoline. When you add gasoline to the
fualtank, do not smoke. Storetha gasoline
container and the mower in an area that
has good ventilation. Also, keep the gasoline away from any flames like the pilot light
of a furnace or any other source of ignition.
If the mower is to be stored for more than a
few weeks, remove the gasoline from the
fuel tank. When inside an enclosure, do
not add gasoline to the fuel tank. Before
you add gasoline move the mower outside
and add gasoline carefully. Before your
start the angina, remove anygasoline from
the outside of the fuel tank or from the
mower. Warm gasoline will expand. Leave
is running. Do nottouch these parts of the
mower. Stop the engine. Let the engine
and transmission cool before servicing the
mowerRemember, exhaustfumesaredangerous. Never operate the engine inside a
building.
When you get a new mower, it can be a new
experience for the family. Tell each person
how a mower can be dangerous. Remember, a mower is not a toy. A mower is not
to be used by children or anyone not old
enough, strong enough or that does not
have experience.
If the mower is not correctly assembled, not
operated correctly, or not regularly serviced, the mower can be dangerous. The
most important rule to follow is always use
good judgement and common sense. Mow
safely and carefully.
Your mower will easily cut thick grass.
Fingers, feet and other parts can also be
cut by the blade. Injuries occur when the
operator does not think and reaches into
the chute opening.
Always operate the
mower as if the blade is rotating. Do not
service or make an adjustment, except to
the carburetor, while the engine is running.
GUIDE
When you mow, remember that children
are attracted to the mower. Always usa
caution when mowing around obstacles
like trees or shrubs or when moving backward. Only mow in a forward direction if
possible. You r visibility is decreased when
you mow backward. Also, the blades are
made to cut while the unit is moving forward. If you mow backward, the cutting
performance decreases.
Before you leave the mower, stop the engine. Remove the key. Disengage and
lower any attachment.
Set the parking
brake. Never mount or dismount from the
seat while the engine is running. An accident can occur if you touch the brake, shift
lever, throttle, clutch, or mower clutch lever
while the engine is running. Mount and
dismount from the seat on the side opposite the discharge chute.
some space in the fu_tank for the gasoline
to expand. Also, the fuel cap has a vent
hole for fuelvapors. Always usathe correct
fuel cap. Failure to follow safety rules
about gasoline will cause fires and explosions, injury to you and damage to the
equipment and other property.
Use only accessories that are factory approved for your mower. The wrong accessory can decrease the safety of the mower
and can even damage the unit. Read and
follow the instructions included with the
accessory and the mower.
If you add gasoline to an engine that is
running or hot, the result can be an explosion. Before you add gasoline, stop the
engine and let the engine cool for several
seconds. Remove dry grass and other
debris from the mower. Keep the mower
clean to improve the performance, help the
engine and transmission run cooler, extend the like of moving parts, and decrease
the danger of a fire.
Use only original equipment or replacement parts that are factory approved for
service. If you need service, select and
Authorized Service Center for your mower.
If you do the work on the unit, follow the
instructions Jn the Owner's/Operator's
Make sure you are in good condition when
you mow. When you mow for several
hours your reflexes will decrease and your
mind will not be as alert. Take a short break
or an accident can occur. If the temperature is hot, use caution to prevent dehydration. If you are tired, angry or not completely alert, do not operate the mower. If
you use alcohol, medication or drugs, do
not use the mower or any type of power
equipment.
Engine speed is a key to safe mowing and
to a good looking lawn. The maximum
speed of the engine was set at the factory.
Do not change the setting of the engine
governor.
Select the maximum engine and ground
speed that is right for the terrain and the
height of the grass. The blade cuts best
when the engine is operating at maximum
Fires and explosions are not the only dangers when working around a mower. The

speed. Also, the grass catcher willf unction
better when the engine is operating at
maximum speed. On slopes, decrease the
ground speed and use care making sure
mower feels safe to operate.
If the weather conditions are bad, do not
mow. If weather conditions become bad,
stop cutting and finish later. It is dangerous
to cut grass in the rain. Always find protection in an electrical storm. If the weather
conditions are extra dry, protect your eyes
with safety glasses from the dust and from
the objects discharged by the mower. Also,
a dust or a pollen mask can help.
Your mower is equipped with a number of
safety devices which are important to the
safety of the operator and bystanders and
must never be changed or removed from
the mower.
If a safety device is lost,
damaged or no longer functions, repair or
replace the device before you operate the
mower.
It is best to mow during the day. If you must
mow at night, make sure there is enough
light for safe operation.
Your mower will require regular maintenance and service.
The maintenance
schedule depends on the hours of use.
Also, mowing conditions can change the
schedule. Check the Owner's/Operator's
Manual for more information. Correct maintenance will help the mower function safely.
Vibration can be a warning of a problem,
Keep all nuts, bolts and screws tight.
The blade is the most dangerous part of the
mower. Frequently check the blade and
the blade mounting fasteners. Keep the
fasteners tight. If the blade hits a solid
object, stop the engine. Remove the wire
from the spark plug. Check for a blade that
is bent, cracked or for other damages.
Before you start the engine, replace the
damaged blade. For safety, replace the
blade every two years.
A sharp blade decreases the work load on
the engine and more evenly cuts grass.
Frequently sharpen the blade for a better
looking cut. Use the left side of the mower
deck to trim near an object.
A grass catcher is a good a accessory for
your mower. For best performance and
safety, make sure the grass catcher is
approved for use with your mower. Follow
the assembly and operation instructions
included with the grass catcher.
Some grass catchers require a special
blade for best performance. Before you
attach, check, or empty the grass catcher,
always stopthe engine. Beforeeach useof
the grass catcher, check for cracks, wear or
deterioration.
Before you use the grass
catcher, replace a damaged part with a
replacement part approved by the factory.
Do not service the mower
(except for the carburetor
adjustment) while the engine is running.
Before il_,l
you service the un t, even I_
with the engine stopped, Itl
always disconnect the wire
from the spark plug to prevent the engine from starting.
If you hit a large object during operation,
stop the engine. Remove the wire from the
sparkplug. Carefully inspect the mower for
damage. Before you start the engine again,
make the necessary repairs. If you feel
new or excessive vibration, immediately
stop the engine and check for the problem.
For you to have a good green lawn, follow
the mowing procedures below. Do not cut
the grass too short. If you cut the grass to
short you can cause the grass to become
yellow or make the lawn look brown. Use
a lower height of cut in cool months when
the grass is thicker. Raise the height of cut
in hot dry periods, if you cut the grass with
GUIDE
a blade that is not sharp or at a slow engine
speed you can damage the grass. Move
the throttle control to the FAST position
when mowing and using the grass catcher.
Also, use a slower ground speed when
using the grass catcher.
Ifyou change the direction or pattern of cut
slightly every time you mow will make the
grass grow stronger and thicker. Do not
add oil or gasoline to the mower while on
the lawn. Spilled oil or gasoline can kill the
grass. In high or thick grass, do not try to
cut all the grass the first time. Raise the
height of cut on the first cutting and lower
the heightfor the next cutting Anotherway
is to cut only part of the width of the mower
and decrease your ground speed (not the
engine) to move more slowly so that the
mower can discharge the grass as it moves
forward.
Understand the controls and how they
work. Learn the ground speed(s) of your
mower. Check the stopping distance required at different travel speeds. Check
the turning radius of the mower. The
controls on your riding mower are different
from an automobile. The throttle is operated by hand and holds the engine speed
constant until it is changed. The location of
the shift lever and the shift pattern is different from that of an automobile. Also, the
brake and clutch systems are different.
Remember the procedures to follow in an
emergency.
Remember, turning off the
ignition switch will stop the blade and the
drive mechanism.
If the traction of the
wheels is lost or does not feel safe, disengage all systems and stop the engine.
Dismount from the mower. Pushthe unif to
a safe place before you begin mowing
again.
Your unit has an electrical system that
includes an seat switch in the seat. The
seat switch detects if the operator is sitting
on the seat. The engine will stop if the
operator leaves the seat when the blade
engagement control is engaged. This seat
switch is a safety device only. It must not
regularly be used to stop the engine or the
blade. There are other control systems on
the mower for this purpose. Always keep
the seat switch and other safety devices
and controls in place and operating for your
protection.
Remember, your mower is a tool that can
be dangerous if it is not correctly used.
Follow the instructions in this Owner's/
Operator's Manual. Safe and careful use
of the mower willgive you ma _,_,safe hours
of problem
free use.

STEERING FEATURE
Because both front and rear wheels turn, an all-wheel steering lawn tractor is very maneuverable.
If the lawn tractor
becomes wedged against a wall, fence or other obstruction,
do the following:
HINTS
For best mowing results, engine should be run at fast throttleand
ground speed controlled by shift control lever position. Forward
speed of the lawn tractor must be controlled in accordance with
thetype and quantityof grass being mowed. The more grassthat
must be cut, the slower the speed forward should be. When
cutting light grass, the forward speed can be increased. By
observing the cutting action of your mower, you can determine
how fast you can travel.
1.
Move transmission control lever to No. 1 position.
2. Turn steering wheel slightly away from obstruction. NOTE:
If you turn sharply (7° or more), rear wheels will turn in opposite
direction of front wheels (turning into obstruction you are trying
to turn away from).
3.
You can reverse
tractor
to back out of dead ends.
CAUTION: Before backing up, stop mower blades. Be sure
tractor
is completely
stopped
before
shifting
into reverse. Before backing up, carefully check the
area behind the lawn tractor for children, pets, and other
obstructions.
Your mower may tend to leave unmowed strips when long and
tender grass is being mowed. Tender grass has a high internal
moisture content and is easily depressed by the lawn tractor
wheels, and may not always spring back in time to be cut. To
overcome this condition, we advise mowing the lawn in a
counterclockwise
direction, overlapping previous cut, which
allows the lifting action of the rotating blades to lift the grass into
the cutting path.
The rear wheels are driven by a transaxle, similar to an
automobile differential. This makes short turns possible and
prevents marring of the lawn. It is possible to spin the drive
wheels of the lawn tractor under adverse conditions. When one
wheel slips, shift your weight over this wheel to obtain more
pulling power. Your lawn traclor is very maneuverable and can
be reversed to back out of dead ends. CAUTION: Disengage
mower blades before backing up. Carefully check area
behind tractor for children or pets before backing up.

MAINTENANCE
BLADE RIEPLACEMEHT (FIG. 8-MAINIr)
BLADE
The cutting blades should be sharp and well-balanced to run
smoothly. Blades should have correct amount of "lift" for
proper cutting and discharge of clippings. Lift is created by upturned bent tip edges of blade ends. As cutting edges of
blades wear, the bent tip edges also wear, decreasing blade
lift, resulting in decreased cutting ability. It is recommended
blades be replaced when upturned ends show signs of wear.

IMPORTANT: Stop engine and Inspect blades at once if
you strike any solid unyielding object. Check to make
sure blade mounting screws are tight. To remove blades:

When replacing blades, be sure all parts are reassembled in
proper order (see Repair Parts section/manual) or severe
vibration will occur. Bent tip edges of blades must be up
toward top of mower deck or blades will not cut. NOTE: Make
sure blade mounting screws are tightened securely. We
recommend using a 10 inch wrench or atorque wrench, ff a

slide idler pulley out away from engine pulley.
Located beneath the main frame are two v-belts. One v-belt
(lawn tractor drive belt) transmits power to the transaxla, which
in turn transmits power to the rear wheels. The other v-belt
transmits power to the mower blades.
4. Ratighten idler pulley mounting screw. NOTE: Belt
retainer should point toward position where running board
meets main frame (FIG. 2-ADJ).
Located on the mower deck is a clutch that disengages power
to the blades and a deck leveling adjustment.
5. Release brake-clutch pedal and recheck pedal for proper
position. Readjust if necessary.
Before any adjustments are made, it is necessary that you understand the function of the brake, clutch, and the brake-clutch
pedal. The pedal disengages the clutch when partially depressed and applies the brake when fully depressed.
Adjustment of the lawn tractor drive belt and brake must be
synchronized
so brake does not grab before clutch
disengages. An incorrect adjustment causes brakes to grab or
hold while power is being transmitted to the rear wheels. Lawn
tractor will try to move with brake applied; this will cause difficulty when shifting from one speed range or direction to another.
6. Check lawn tractor brake adjustment as outlined in
paragraph Lawn Tractor Brake Adjustment.
To replace drive belt, you must remove mower deck.
Removal of deck isn't necessary for other adjustments, but if
several adjustments are needed, it will be more convenient ff
deck is removed.
At no time during the adjustment or repairs _
can the lawn tractor be lifted more than 20
Inches from level position without taking the
following precautions:
1. Remove gasoline from tank and run engine until carburetor is dry.
2. Remove battery. (see BA'rrERY REMOVAL
