OPERATION
ADD GASOLINE
• Fill fuel tank to bottom of filler neck. Do not overfill.
Use fresh, clean, regular unleaded gasoline with a
minimum of 87 octane. (Use of leaded gasoline will
increase carbon and lead oxide deposits and reduce
valve life). Do not mix oil with gasoline. Purchase fuel
in quantities that can be used within 30 days to assure
fuel freshness.
CAUTION: Fill to within 1/2 inch of top
of fuel tank to prevent spills and to
allow for fuel expansion. If gasoline
is accidentally spilled, move machine
away from area of spill. Avoid creating
any source of ignition until gasoline
vapors have disappeared.
Wipe off any spilled oil or fuel. Do not
store, spill or use gasoline near an
open flame.
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING.
CAUTION: Alcohol blended fuels (called gaso-
hol or using ethanol or methanol) can attract
moisture which leads to separation and forma-
tion 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 storage 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 Instructions for additional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.
Fig. 13
TO START ENGINE (See Fig. 13)
CAUTION: KEEP TINE CONTROL IN “OFF”
POSITION WHEN STARTING ENGINE.
When starting engine for the first time or if engine has run
out of fuel, it will take extra pulls of the recoil starter to
move fuel from the tank to the engine.
1. Make sure spark plug wire is properly connected.
2. Place the fuel valve to the "ON" position.
3. To start a cold engine, move the choke lever to the
"ON" position.
4. Move the throttle lever away from the "SLOW" position,
about 1/3 of the way toward the "FAST" position.
5. Turn the engine switch to the "ON" position. Pull rope
out slowly until engine reaches start of compression
cycle (rope will pull slightly harder at this point).
6. Pull recoil starter handle quickly. Do not let starter
handle snap back against starter. Repeat if neces-
sary.
NOTE: IF ENGINE FIRES BUT DOES NOT START, MOVE
CHOKE CONTROL TO HALF CHOKE POSITION. PULL RECOIL
STARTER HANDLE UNTIL ENGINE STARTS.
7. If the choke lever has been moved to the "ON" position
to start the engine, gradually move it to the opposite
position as the engine warms up.
NOTE: A WARM ENGINE REQUIRES LESS CHOKING TO
START.
8. Move throttle control to desired running position.
9. Allow engine to warm up for a few minutes before
engaging tines.

CULTIVATING
Cultivating is destroying the weeds between rows to pre-
vent them from robbing nourishment and moisture from the
plants. At the same time, breaking up the upper layer of
soil crust will help retain moisture in the soil. Best digging
depth is 1" to 3" (2.5-7.5 cm). Lower the outer side shields
to protect small plants from being buried.
• Cultivate up and down the rows at a speed which will
allow tines to uproot weeds and leave the ground in
rough condition, promoting no further growth of weeds
and grass (See Fig. 15).
Fig. 15
TILLING HINTS
CAUTION: Until you are accustomed to
handling your tiller, start actual field use
with throttle in slow position (mid-way
between “FAST” and “IDLE”).
• Tilling is digging into, turning over, and breaking up
packed soil before planting. Loose, unpacked soil helps
root growth. Best tilling depth is 4" to 6" (10-15 cm).
A tiller will also clear the soil of unwanted vegetation.
The decomposition of this vegetable matter enriches
the soil. Depending on the climate (rainfall and wind),
it may be advisable to till the soil at the end of the
growing season to further condition the soil.
• You will find tilling much easier if you leave a row
untilled between passes. Then go back between tilled
rows. (See Fig. 14) There are two reasons for doing
this. First, wide turns are much easier to negotiate than
about-faces. Second, the tiller won’t be pulling itself,
and you, toward the row next to it.
• Soil conditions are important for proper tilling. Tines will
not readily penetrate dry, hard soil which may contribute
to excessive bounce and difficult handling of your tiller.
Hard soil should be moistened before tilling; however,
extremely wet soil will “ball-up” or clump during tilling.
Wait until the soil is less wet in order to achieve the
best results. When tilling in the fall, remove vines and
long grass to prevent them from wrapping around the
tine shaft and slowing your tilling operation.
• Do not lean on handle. This takes weight off the wheels
and reduces traction. To get through a really tough
section of sod or hard ground, apply upward pressure
on handle or lower the depth stake.
TINE SHEAR PINS
The tine assemblies on your tiller are secured to the tine
shaft with shear pins (See “TINE REPLACEMENT” in the
Service and Adjustments section of this manual).
If the tiller is unusually overloaded or jammed, the shear
pins are designed to break before internal damage occurs
to the transmission.
• If shear pin(s) break, replace only with those shown in
the Repair Parts section of this manual.

12
MAINTENANCE
GENERAL RECOMMENDATIONS
The warranty on this tiller does not cover items that have
been subjected to operator abuse or negligence. To receive
full value from the warranty, the operator must maintain
tiller as instructed in this manual.
Some adjustments will need to be made periodically to
properly maintain your tiller.
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 tines and belts for wear.
A new spark plug and clean air filter assure proper air-
fuel mixture and help your engine run better and last
longer.
BEFORE EACH USE
• Check engine oil level.
• Check tine operation.
• Check for loose fasteners.
LUBRICATION
Keep unit well lubricated (See “LUBRICATION CHART”).

TO CHANGE ENGINE OIL (See Figs. 16 and 17)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
• Be sure tiller is on level surface.
• Oil will drain more freely when warm.
• Use a funnel to prevent oil spill on tiller, and catch oil
in a suitable container.
• Remove drain plug. For easier removal of plug use
7/16 12 Pt. socket with extension.)
• Tip tiller forward to drain oil.
• After oil has drained completely, replace oil drain plug
and tighten securely.
• Remove oil filler plug. Be careful not to allow dirt to
enter the engine.
• Refill engine with oil. See “CHECK ENGINE OIL LEVEL”
in the Operation section of this manual.
ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service
classification SG-SL. Select the oil’s SAE viscosity grade
according to your expected temperature.
NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
40°F (4°C). Check your engine oil level more frequently to
avoid possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at
least once a year if the tiller is not used for 25 hours in
one year.
Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil filler plug securely

MAINTENANCE
Fig. 19
MUFFLER
Do not operate tiller without muffler. Do not tamper with
exhaust system. Damaged mufflers or spark arresters
could create a fire hazard. Inspect periodically and replace
if necessary. If your engine is equipped with a spark arrester
screen assembly, remove every 50 hours for cleaning and
inspection. Replace if damaged.
COOLING SYSTEM (See Fig. 19)
Your engine is air cooled. For proper engine performance
and long life keep your engine clean.
• Clean air screen frequently using a stiff-bristled brush.
• Remove blower housing and clean as necessary.
• Keep cylinder fins free of dirt and chaff.

SPARK PLUG
Replace spark plugs at the beginning of each tilling sea-
son or after every 25 hours of use, whichever comes first.
Spark plug type and gap setting are shown in “PRODUCT
SPECIFICATIONS” on page 3 of this manual.
TRANSMISSION
Your transmission is sealed and will not require lubrication
unless serviced.
CLEANING
Do not clean your tiller when the engine and transmission
are hot. We do not recommend using pressurized water
(garden hose, etc.) to clean your unit unless the gasket
area around the transmission and the engine muffler, air
filter and carburetor are covered to keep water out. Water
in engine will shorten the useful life of your tiller.
• Clean engine, wheels, finish, etc. of all foreign matter.
• Keep finished surfaces and wheels free of all gasoline,
oil, etc.
• Protect painted surfaces with automotive type wax.

ENGINE
Maintenance, repair, or replacement of the emission control
devices and systems, which are being done at the custom-
ers expense, may be performed by any non-road engine
repair establishment or individual. Warranty repairs must
be performed by an authorized engine manufacturer's
service outlet.
IMPORTANT: NEVER TAMPER WITH THE ENGINE
GOVERNOR, WHICH IS FACTORY SET FOR PROPER ENGINE
SPEED. OVERSPEEDING THE ENGINE ABOVE THE FACTORY
HIGH SPEED SETTING CAN BE DANGEROUS. IF YOU THINK
THE ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING,
CONTACT YOUR NEAREST AUTHORIZED SERVICE CENTER/
DEPARTMENT, WHICH HAS THE PROPER EQUIPMENT AND
EXPERIENCE TO MAKE ANY NECESSARY ADJUSTMENTS.
TIRE CARE
CAUTION: When mounting tires, un-
less beads are seated, overinflation
can cause an explosion.
• Maintain 20 pounds of tire pressure. If tire pressures
are not equal, tiller will pull to one side.
• Keep tires free of gasoline or oil which can damage
rubber.
TO REMOVE WHEEL (See Fig. 21)
• Place blocks under transmission to keep tiller from
tipping.
• Remove hairpin clip and clevis pin from wheel.
• Remove wheel and tire.

GROUND DRIVE BELT ADJUSTMENT (See
Fig. 24)
For proper belt tension, the extension spring should have
about 5/8 inch (16 mm) stretch when drive control bar is
in “ENGAGED” position. This tension can be attained as
follows:
• Loosen cable clip screw securing the drive control
cable.
• Slide cable forward for less tension and rearward for
more tension until about 5/8 inch (16 mm) stretch is
obtained while the drive control bar is engaged.
• Tighten cable clip screw securely.

• To maintain the superb tilling performance of this ma-
chine the tines should be checked for sharpness, wear,
and bending, particularly the tines which are next to
the transmission. If the gap between the tines exceeds
3-1/2 inches they should be replaced or straightened
as necessary.
• New tines should be assembled as shown in Fig.

A badly worn tine causes your tiller to work harder and dig
more shallow. Most important, worn tines cannot chop and
shred organic matter as effectively nor bury it as deeply as
good tines. A tine this worn needs to be replaced.

STORAGE
ENGINE OIL
Drain oil (with engine warm) and replace with clean oil. (See
“ENGINE” in the Maintenance section of this manual).
CYLINDER(S)
• Remove spark plug.
• Pour 1 ounce (29 ml) of oil through spark plug hole into
cylinder.
• Pull starter handle slowly several times to distribute
oil.
• Replace with new spark plug.
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 unit indoors and cover it to give
protection from dust and dirt.
• Cover your unit with a suitable protective cover that
does not retain moisture. Do not use plastic. Plastic
cannot breathe which allows condensation to form and
will cause your unit to rust.
IMPORTANT: NEVER COVER TILLER WHILE ENGINE AND
EXHAUST AREAS ARE STILL WARM.
Immediately prepare your tiller for storage at the end of the
season or if the unit will not be used for 30 days or more.
WARNING: Never store the tiller with
gasoline in the tank inside a building
where fumes may reach an open flame
or spark. Allow the engine to cool before
storing in any enclosure.
TILLER
• Clean entire tiller (See “CLEANING” in the Maintenance
section of this manual).
• Inspect and replace belts, if necessary (See belt re-
placement instructions in the Service and Adjustments
section of this manual).
• Lubricate as shown in the Maintenance section of this
manual.
• Be sure that all nuts, bolts and screws are securely
fastened. Inspect moving parts for damage, breakage
and wear. Replace if necessary.
• Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
ENGINE
FUEL SYSTEM
IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS
FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH
AS THE CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK
DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT
ALCOHOL BLENDED 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 engine or carburetor cleaner products in the
fuel tank or permanent.
NOTE: Fuel stablizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during
storage. Add stabilizer to gasoline in fuel tank or storage
container. Always follow the mix ratio found on stablizer
container. Run engine at least 10 minutes after adding
stablizer to allow the stabilizer to reach the carburetor.
Do not drain the gas tank and carburetor if using fuel
stabilizer.
