Never operate the tiller without proper guards, plates,
or other safety protective devices in place.
Keep children and pets away.
Do not overload the machine capacity by attempting
to till too deep at too fast a rate.
Never operate the machine at high speeds on slippery
surfaces. Look behind and use care when backing.
Never allow bystanders near the unit.
Use only attachments and accessories approved by
the manufacturer of the tiller.
Never operate the tiller without good visibility or light.
Be careful when tilling in hard ground. The tines may
catch in the ground and propel the tiller forward. If this
occurs, let go of the handlebars and do not restrain the
machine.

Do not put hands or feet near or under rotating parts.
Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden
hazards or traffic. Do not carry passengers.
After striking a foreign object, stop the engine (motor),
remove the wire from the spark plug, thoroughly inspect
the tiller for any damage, and repair the damage before
restarting and operating the tiller.
Exercise caution to avoid slipping or falling.
If the unit should start to vibrate abnormally, stop the
engine (motor) and check immediately for the cause.
Vibration is generally a warning of trouble.
Stop the engine (motor) when leaving the operating
position.
Take all possible precautions when leaving the machine
unattended. Disengage the tines, shift into neutral, and
stop the engine.
Before cleaning, repairing, or inspecting, shut off the
engine and make certain all moving parts have stopped.
Disconnect the spark plug wire, and keep the wire away
from the plug to prevent accidental starting. Disconnect
the cord on electric motors.
Do not run the engine indoors; exhaust fumes are
dangerous.

STARTER HANDLE UNTIL ENGINE STARTS.

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.

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.

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.

NOTE: IF ENGINE DOES NOT START, SEE TROUBLESHOOTING
POINTS.

CAUTION: 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. 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.

OPERATION
CULTIVATING

TILLING HINTS

Cultivating is destroying the weeds between rows to prevent 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. 16).
• Do not lean on handle, this takes weight off the wheels,
reduces traction, and may cause the tiller to skip over
the ground.
• Always lower the drag stake when using the forward
rotating tine drive.

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. 15) 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.

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
each time you check the oil level.
TO CHANGE ENGINE OIL (See Figs. 17 and 18)
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.

CAUTION: Petroleum solvents, such
as kerosene, are not to be used to
clean cartridge. They may cause deterioration of the cartridge. Do not oil
cartridge. Do not use pressurized air
to clean or dry cartridge.

COOLING SYSTEM (See Fig. 20)

SPARK PLUG

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.

Replace spark plugs at the beginning of each tilling season 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.

TINE REPLACEMENT
(See Figs. 25, 26, and 27)
CAUTION: Tines are sharp. Wear
gloves or other protection when handling tines.

•

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.

NEW TINE

To maintain the superb tilling performance of this machine 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.
For tines that are slightly worn, the bolted tine and
hub assemblies can be switched between sides to
continue tilling in the same tilling mode if tilling in a
different mode is desired then the bolted tine and hub
assemblies should be switched back to their original
side so that the tine edge with the least wear will be
used.

STORAGE
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.

ENGINE OIL
Drain oil (with engine warm) and replace with clean oil. (See
“ENGINE” in the Maintenance section of this manual).

CAUTION: 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.

CYLINDER(S)
•
•

TILLER
•
•
•
•
•

•

Clean entire tiller (See “CLEANING” in the Maintenance
section of this manual).
Inspect and replace belts, if necessary (See belt replacement 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.

•

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
•
•
•
•

ENGINE

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.

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.

•

Empty the fuel tank by starting 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.
• Use fresh fuel next season.
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 empty the gas tank and carburetor if using fuel
stabilizer.
