• Only allow responsible adults, who are familiar with the instructions, to operate the machine.

• Clear the area of objects such as rocks, toys, wire, etc, which could be picked up and thrown by the blade.

• Be sure the area isclear of otherpeople before mowing. Stop machine if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessary. Always leek down and behind before and while backing.

,, 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 guard in place.

° Slow down before turning.

• Never leave a running machine unattended. Nways turn off blades, set parking brake, stop engine, and remove keys before dismounting.

• Turn off blades when not mowing.

° Stop engine before removing grass catcher or unclogging

chute.

• Mow only in daylight or good artificial light. ° Do not operate the machine while under the influence of

aicoho! or drugs.

° Watch for traffic when operating near or crossing roadways.

• Use extra care when loading or unloading the machine into a trai_eror truck.

U, SLOPE OPERATION

Slopes are a major factor related to toss-of=controland tipover accidents, which can result in severe injury or death. AHslopes require extra caution. Ifyou cann otbackup theslope orifyou feel

uneasy on it, do not mow it. DO:

• Mow up and down slopes, not across.

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

° Watch for holes, ruts, or bumps. Uneven terrain could

overturn the machine. Tall grass can hide obstacles.

• Use slow speed. Cheese alow gear so that you wilf not have to stop or shift while on the slope.

• Follow the manufacturer's recommendations for wheel weights or counterweights to improve stability.

= Use extra care with grass catchers or other attachments.

These can change the stability of the machine.

• Keep all movement on the slopes slow and gradual Do not

make sudden changes in speed or direction.

° Avoid starting or stopping on a slope. If tires lose traction,

disengage the blades and proceed slowly straightdewn the slope.

DO NOT:

• Do not turn on slopes unless necessary, and then, turn slowly

and gradually downhill, if possible.

. Do notmow near drop-offs, ditches, or embankments. The

mower could suddenly turn over if a wheel is over the edge

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

• Do not mow on wet grass. Reduced traction could cause sliding.

• Do not try to stabilize the machine by putting your foot on the ground.

• Do not use grass catcher on steep slopes.

ill. CHILDREN Tragic accidents can occur if the operator is not afert to the

presence ofchildren. Children are often attracted tothe machine and the mowing activity. Neverassume that children will remain where you last saw them.

• Keep children out of the mowing area and underthe watchful care of another responsible adult.

• Be alert and tum machine offifchildren enter the area.

• Before and when backing, look behind and down for small children.

= Never carry children. They may fall off and be seriously

injured or interfere with safe machine operation.

• Never allow children to operate the machine.

• Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

HOW TO SET UP YOUR TRACTOR

PREPARE BATTERY (See Fig. 3)

CAUTION: Wear eye and face shield. Wash hands or clothing immediately ff

_ accidentallyincontactwithbatteryacid.

Your tractor has a battery charging system which is suffi- cient for normal use. However; periodic charging of the battery with an automotive charger will extend its life.

See instructions packed with vent caps in parts bag.

o Fill battery with acid. Fitl each cell until it reaches the

bottom of the vent wells. Do not overfill.

Allow battery to stand and settle for at least thirty minutes. After standing, check the level of acid. If

below the vent wells, add more acid until the correct level is reached.

While battery is standing (after adding acid) and later, while battery is being charged, continue with assembly of tractor.

ItV'iPORTANT: TO MAXiMiZE THE LIFE OF YOUR BATTERY, IT IS NECESSARY THAT THE BATTERY BE

CHARGED BEFORE USE. FAILURE TO CHARGE

BATTERY CAN RESULT tN A SHORTENED BATTERY

LIFE. o Charge battery at a rate of 6 amperes for 1 hour. Use

a 12 volt battery charger. Observe all safety precau- tions required for battery charging.

* Check the acid level after the battery is charged. If the

acid has fallen below the correct level, add distilled or iron free water,

o Install the vent caps to cover the vent wells. Wash the

top of the battery with water to remove any acid, then wipe dry.

, Check battery case for leakage to make sure that no

damage has occurred in handling.

o Dispose of excess battery acid. Neutralize acid for

disposal by adding it to four inches of water in a five

gallon ptastic container. Stir with a wooden or plastic

paddle while adding baking soda until the addition of

more soda causes no more foaming.

Follow instructions on how to installbattery_

Oo not smoke. Fumes from charged battery acid are explosive.

ADD GASOL|NE

• Fi!f fuel tank. Use fresh, clean, regular unleaded gasoline. (Use of leaded gasoline wilt increase carbon

and lead oxide deposits and reduce valve life).

IMPORTANT: WHENOPERAT]NG1NTEMPERATURES BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE

GASOLINE TO HELP iNSURE GOOD COLD WEATHER STARTING.

WARNING: Experience indicates that alcohot blended

fuels (called gasoho_ or using ethanot or methanol) can

attract moisture which leads toseparation and formation of acids during storage. Acidic gas can damage the fuel

system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before stor-

age of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are

empty. Use fresh fuel next season. See Storage Instruc- tions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur,

CAUTION: Fill to bottom of gas tank filler neck. Do not overfill. Wipe off any spilled oil or fuel Do not store, spill or

use g_ine near an open flame.

TO START ENGINE (See Fig. 8)

When starting engine for the firsL time or if engine has run

out of fuel, itwitt take extra cranking time to move fuel from the tank to the engine.

- Depress clutch/brake pedal and set parking brake. * Place gearshift lever in "NEUTRAL" position,

Move attachment clutch to "DISENGAGED" position. Pull choke control out to "CHOKE" position for cold

engine start. For warm engine start do not use choke control.

* Move throttle control to midway between "FAST" and

"SLOW" positions.

Insert key into ignition and turn key clockwise to"START"

position and release key as soon as engine starts. Do

not run starter continuously for more than fifteen sec- onds per minute, if engine does not start after several attempts, move throttle control to "FAST" position, wait

a few minutes and try again. When engine starts, slowly push choke control in.

. Move throttle control to "FAST" position.

Atlow engine to warm up for a few minutes before engaging drive or attachments.

NOTE: tf at a high altitude (above 3000 feet) or in cold temperatures (below 32 ° F), the carburetor fuel mixture may need to be adjusted for best engine performance. See "TO ADJUST CARBURETOR" in the Service and Adjust-

ments section of this manual.

GENERAL RECOMMENDATIONS

The warranty on this tractor does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must main-

tain tractor as instructed in this manual. Some adjustments wilt need to be made periodically to

properly maintain your tractor. All adjustments in the Service and Adjustments section of

this manual should be checked at least once each season.

Once a year you should replace the spark plug, clean or replace air filter, and check blades and belts for wear. A new spark plug and clean air filter assure proper air-fuel mixture and helpyour engine run better and last longer.

BEFORE EACH USE

Check engine oil level.

, Check brake operation.

Check tire pressure.

o Check for loose fasteners.

IMPORTANT: DO NOT OIL OR GREASE THE PIVOT POINTS WHICH HAVE SPECIAL NYLON BEARINGS. VISCOUS LUBRI-

CANTS WILL ATTRACT DUST AND DIRT THAT WiLL SHORTEN THE LIFE OF THE SELF-LUBRICATING BEARINGS, IF YOU FEEL THEY MUST BE LUBRICATED, USE ONLY A DRY, POW-

TO ADJUST THROTTLE CONTROL CABLE

(See Fig. 28)

The throttle control has been preset at the factory and

adjustment should not be necessary. Check adjustment as

described below before loosening cable, if adjustment is

necessary, proceed as follows:

o With engine not running, move throttle control lever to

"FAST" position.

o Check that throttle lever is against high speed stop. If

itis not, loosen clamp screw and pull throttle cable until lever is against stop. Tighten clamp screw securely.

TO ADJUST CARBURETOR (See Fig. 29)

The carburetor has been present at the factory and adjust-

ment should not be necessary. However, minor adjustment may be required to compensate for differences in fuel,

temperature, altitude or load. If the carburetor does not

need adjustment, proceed as follows: in general, turning the adjusting needles in (clockwise)

decreases the supply of fuel to the engine giving a leaner

fuel/air mixture. Turning the adjusting needles out (coun- terclockwise) increases the supply of fuel to the engine

giving a richer fuet/air mixture. IMPORTANT: DAMAGE TO THE NEEDLES AND THE

SEATS tN CARBURETOR MAY RESULT IF SCREW IS TURNED IN TOO TIGHT.

PRELIMINARY SETTING -

• Be sure you have a clean air filter, and the throttle control cable and choke are adjusted properly (see

above).

With engine off turn idle fuel adjusting needle in (clock-

wise) closing it finger tight and then turn out

(counterclockwise) 1-1/4 turns.

* Turn main fuel adjusting needle in (clockwise) closing

finger tight and then turn out (counterclockwise) 1 turn.

FINAL SETTING -

* Start engine and allow to warm for five minutes. Make

final adjustments with engine running and shift/motion control lever in "NEUTRAL" position.

With throttle control lever in "FAST" position, turn main fuel adjusting needle in (clockwise) until engine begins to die then turn out (counterclockwise) until engine runs rough. Turn needle to a point midway between

those two positions.

Idle speed setting- With throttle control lever in"SLOW" position, engine should idle at 1400 RPM. If engine

idles too stow or fast, turn idle speed adjusting screw in

or out until correct idle is attained.

- Idle fue! needle setting - With throttle control lever in "SLOW" position, turn idle fuel adjusting needle in (clockwise) until engine begins to die and then turn out (counterclockwise) until engine runs rough. Turn needle

to a point midway between those two positions,

* Recheck idle speed. Readjust if necessary. ACCELERATION TEST -

- Move throttle control lever from "SLOW" to "FAST" position. If engine hesitates or dies, turn idle mixture

screw out (counterclockwise) 1/8 turn. Repeat test and continue to adjust, if necessary, until engine acceler- ates smoothly.

High speed stop is factory adjusted. Do not adjust-damage may result.

IMPORTANT: NEVER TAMPER WITH THE ENGINE GOVERNOR, WHICH IS FACTORY SET FOR PROPER ENGINE SPEED. QVERSPEEDING THE ENGINE ABOVE

THE FACTORY HIGH SPEED SETTING CAN BE

DANGEROUS. IFYOUTHINKTHE ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING, CONTACT YOUR

NEAREST AUTHORIZED SERVICE CENTER, WHICH HAS PROPER EQUIPMENT AND EXPERIENCE TO MAKE ANY

FUELS (CALLED GASOHOL OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS

TO SEPARATION AND FORMATION OF ACIDS DURING

STORAGE. ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM OF AN ENGINE WHILE IN STORAGE.

* Drain the fuel tank.

, Start the engine and let it run until the fuel lines and

carburetor are empty,

, Never use engirte or carburetor cleaner products in the

fuel tank or permanent damage may occur.

, Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during stor-

age. Add stabilizer to gasoline in fuel tank or storage container, Always follow the mix ratio found on stabilizer

container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carbu rotor. Do

not drain the gas tank and carburetor if using fuel stabilizer.

ENGINE OiL

Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Customer Responsibilities

section of this manual),

CYLINDERS

• Remove spark plug(s).

• Pour one ounce of oil through spark plug hole(s) into

cylinder(s).

• Turn ignition key to"START" position for a few seconds to distribute oil.

= Replace with new spark plug(s).

OTHER

Do not store gasoline from one season to another.

• Replace your gasoline can if your can starts to rust.

Rust and/or dirt in your gasoline will cause problems.

• If possible, store your tractor indoors and cover it to

give protection from dust and dirt.

• Cover your tractor with a suitable protective cover that

does not retain moisture. Do not use plastic. Plastic

cannot breathe which allows condensation to form and witl cause your tractor to rust.

IMPORTANT: NEVER COVER TRACTOR WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM,
