TILLING
The speed and depth of tilling is regulated by the position
of the depth stake and wheel height.
The depth stake should always be below the wheels for
digging. It serves as a brake to slow the tiller’s forward
motion to enable the tines to penetrate the ground. Also,
the more the depth stake is lowered into the ground the
deeper the tines will dig.
DEPTH STAKE (See Fig. 6)
Adjust depth stake by removing the hairpin clip and clevis
pin. Change depth stake to desired position. Replace the
clevis pin and hairpin clip.
• For normal tilling, set depth stake at the second or third
hole from the top.

FILL FUNNELS.
FILL ENGINE WITH OIL (See Fig. 7)
• With engine level, remove engine oil filler plug.
• Fill engine with oil to point of overflowing. For approx
imate capacity see “PRODUCT SPECIFICATIONS” on
page 3 of this manual.
• Tilt tiller back on its wheels and then re-level.
• With engine level, refill to point of overflowing if nec
essary. Replace oil filler plug.
• For cold weather operation you should change oil for
easier starting (See “OIL VISCOSITY CHART” in the
Maintenance section of this manual).
• To change engine oil, see the Maintenance section of
this manual.
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

BREAKING IN YOUR TILLER
Break-in your belt(s), pulleys and tine control before you
actually begin tilling.
• Start engine, tip tines off ground by pressing handles
down and engage tine control to start tine rotation.
Allow tines to rotate for five minutes.
• Check tine operation and adjust if necessary. See “TINE
OPERATION CHECK” in the Service and Adjustments
section of this manual.
Soil conditions are important for propertilling.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.
You will find tilling much easier if you leave a row un
filled between passes. Then go back between tilled
rows. (See Fig. 9) 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.
Set depth stake and wheel height for shallow tilling
when working extremely hard soil or sod. Then work
across the first cuts at normal depth.
TILLING HINTS
CAUTION: Until you are accustomed
to handling your tiller, start actual field
A
To help tiller move forward, lift up the handles slightly (thus
lifting depth stake out of ground). To slow down the tiller,
press down on handles.
If you are straining or tiller is shaking, the wheels and depth
stake are not set properly in the soil being tilled.The proper
setting of the wheels and depth stake is through trial and
error and depends upon the soil condition. (The harder or
wetter the ground, the slower the engine and tine speed
needed. Under these poor conditions, at fast speed the
tiller will run and jump over the ground).
A properly adjusted tiller will dig with little effort from the
operator.
• Tilling is digging into, turning over, and breaking up
packed soil before planting. Loose, unpacked soil helps
root growth. Best tilling depth is 4"-6". A tiller will also

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.
use with throttle in slow position.
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 T'-3".
• You will probably not need to use the depth stake. Begin
by tipping the depth stake forward until it is held by the
stake spring.
• 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. 10).

full value from the warranty, 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.

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
32°F (0°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. 11 and 12)

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.
WARNING: Never store the tiller with
gasoline in the tank inside a building
A
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
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.
FUEL SYSTEM
IMPORTANT: IT IS IMPORTANTTO PREVENTGUM DEPOSITS
FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH
ASTHE CARBURETOR, FUEL FILTER. FUEL HOSE, OR TANK
DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT
ALCOHOL BLENDED FUELS (CALLED GASOHOL OR USING
ETHANOLOR METHANOL) CAN ATTRACT MOISTUREWHiCH
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.
