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.

FIG. 7

ADD GASOLINE

• Fill fuel tank to bottom of fi ller neck. Do not overfi ll.
Use fresh, clean, regular un lead ed 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 quan ti ties 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 ac­ ci den tal ly 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 fl ame.

PLUG

CAUTION: Alcohol blended fuels (called
gas o hol or using ethanol or methanol) can at­tract moisture which leads to sep a ra tion and
for ma 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 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
sea son. See Storage In struc tions for additional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.

TO START ENGINE (See Fig. 8)

CAUTION: Keep drive control bar in
“DISENGAGED” position when start­ ing en gine.

When starting engine for the fi rst 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.

• Make sure spark plug wire is prop er ly connected.

• Move shift lever indicator to “N” (neutral) position.

• Place throttle control in “FAST” position.

• Move choke control to full “CHOKE” position. Grasp
recoil starter handle with one hand and grasp tiller
handle with other hand. Pull rope out slowly until en­gine reaches start of com pres sion cycle (rope will pull
slightly harder at this point).

• Pull recoil starter handle quickly. Do not let starter
handle snap back against starter. Repeat if neces­sary.

• If engine fi res but does not start, move choke control
to half choke position. Pull recoil starter handle until
engine starts.

• When engine starts, slowly move choke control to
“RUN” position as engine warms up.

NOTE: A warm engine requires less choking to start.

• Move throttle control to desired running position.

• Allow engine to warm up for a few minutes before
engaging tines.

NOTE: If at a high altitude (above 3000 feet) or in cold
temperatures (below 32°F), the carburetor fuel mix ture may
need to be adjusted for best engine per for mance. See “TO
ADJUST CARBURETOR” in the Service and Ad just ments
section of this manual.

NOTE: If en gine does not start, see trou ble shoot ing
points.

IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE

BREAKING IN YOUR TILLER

Break-in your belts, 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 fi ve minutes.

• Check tine operation and adjust if necessar y. See “TINE
OPERATION CHECK” in the Service and Ad just ments
sec tion of this manual.

TILLING HINTS

CAUTION: Until you are accustomed to
handling your tiller, start ac tu al fi eld use
with throttle in slow po si tion (mid-way
be tween “FAST” and “IDLE”).

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 con di tion. (The harder or
wetter the ground, the slower the engine and tine speed
needed. Under these poor con di tions, 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" to 6" (10-15 cm).
A tiller will also clear the soil of unwanted vege ta tion.
The decomposition of this vegetable mat ter en rich es
the soil. Depending on the climate (rain fall and wind),
it may be advisable to till the soil at the end of the
growing season to further condition the soil.

• Soil conditions are important for proper tilling. Tines will
not readily penetrate dry, hard soil which may con trib ute
to excessive bounce and diffi cult handling of your tiller.
Hard soil should be mois tened 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 fi nd tilling much easier if you leave a row un­tilled 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. Sec ond, 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 fi rst cuts at normal depth.

FIG. 9

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).

• 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 con di tion, promoting no fur ther growth of weeds
and grass (See Fig. 10).

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 tractor is not used for 25 hours in one
year.

Check the crankcase oil level before starting the engine
and after each fi ve (5) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil fi ller plug securely
each time you check the oil level.

TO CHANGE ENGINE OIL (See Figs. 11 and 12)

Determine temperature range expected before oil change.
All oil must meet API service classifi cation SF-SJ.

• Be sure tiller is on level surface.

• Oil will drain more freely when warm.

• Catch oil in a suitable container.

• Remove drain plug.

• Tip tiller forward to drain oil.

• After oil has drained completely, replace oil drain plug
and tighten securely.

• Remove oil fi ller plug. Be careful not to allow dirt to

checking tine operation.

FINAL CHECK “OFF” POSITION

• With tine control “OFF” (up), push down on handle to
raise tines off the ground.

• Slowly pull recoil starter handle while observing tines.
Tines should not rotate.

• If tines rotate, place loop of idler spring in a lower link
of chain and retest.

FINAL CHECK “ON” POSITION

• With tine control “ON” (held down to handle) push down
on handle to raise tines off the ground.

• Slowly pull recoil starter handle while observing tines.
Tines should rotate forward.

• If tines do not rotate, place loop of idler spring in a
higher link of chain and retest.

NOTE: If “ON” position check required adjustment, re check

TO ADJUST CARBURETOR

The carburetor has a high speed fi xed jet and has been
preset at the factory and ad just ment should not be nec­ es sary. How ev er, minor ad just ments may be required to
compensate for dif fer ences in fuel, temperature, altitude or
load. If the carburetor does need adjustment, see engine
manual.

IMPORTANT: NEVER TAMPER WITH THE EN GINE
GOVERNOR, WHICH IS FACTORY SET FOR PROPER ENGINE
SPEED. OVER SPEED ING THE ENGINE ABOVE THE FACTORY
HIGH SPEED SET TING CAN BE DANGEROUS. IF YOU THINK
THE ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING,
CON TACT YOUR NEAREST AUTHORIZED SERVICE CENTER/
DEPARTMENT, WHICH HAS THE PROPER EQUIP MENT AND
EX PE RI ENCE TO MAKE ANY NEC ES SARY ADJUSTMENTS.

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 build ing
where fumes may reach an open fl ame
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 nec es sary (See belt re­ place ment in struc tions in the Service and Ad just ments
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, break age
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 man ual).

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 pro tec tive cover that
does not retain moisture. Do not use plastic. Plastic
cannot breathe which allows con den sa tion 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.

• Drain the fuel tank.

• Start the engine and let it run until the fuel lines and
car bu re tor 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.
