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.
TO TRANSPORT
CAUTION: Beforeliftingortransporting,
allow tiller engine and muffler to cool.
Disconnect spark plug wire. Drain
gasoline from fuel tank.
CAUTION: Fill to within 1/2 inch of top
offueltanktopreventspillsandtoallow
for fuel expansion. If gasoline is ac-
cidentally spilled, move machine away
from area of spill. Avoid creating any
sourceofignitionuntilgasolinevapors
have disappeared.
Wipe off any spilled oil or fuel. Do not
store, spill or use gasoline near an
open flame.
AROUND THEYARD
•
Release the depth stake pin. Move the depth stake
down to the top hole for transporting the tiller. Place
depth stake pin in hole of depth stake to lock in posi-
tion. This prevents tines from scuffing the ground.

STARTING.
•
•
•
Disconnect spark plug wire.
Drain fuel tank.
Transport in upright position to prevent oil leakage.
CAUTION: Alcohol blended fuels (called
gasohol or using ethanol or methanol) can at-
tract 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. SeeStorageInstructionsforadditional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.
BEFORE STARTING ENGINE
IMPORTANT: BE VERY CAREFUL NOT TO ALLOW DIRT
TO ENTER THE ENGINE WHEN CHECKING OR ADDING
OIL OR FUEL. USE CLEAN OIL AND FUEL AND STORE IN
APPROVED, CLEAN, COVERED CONTAINERS. USE CLEAN
FILL FUNNELS.
CHECK ENGINE OIL LEVEL (See Fig. 12)

Tilling is digging into, turning over, and breaking up
packedsoilbeforeplanting.Loose,unpackedsoilhelps
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.
Soilconditionsareimportantforpropertilling.Tineswill
notreadilypenetratedry,hardsoilwhichmaycontribute
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-
tilled 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.

Make sure spark plug wire is properly connected.
Move shift lever indicator to “N” (neutral) position.
Place throttle control in “FAST” position.
Turn fuel shut-off valve 1/4 turn to open position.
Move choke control to 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 compression cycle (rope will
pull slightly harder at this point).
•
•
Pull recoil starter handle quickly. Do not let starter
handle snap back against starter.
If engine fires 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 (3000 feet) or in cold
temperatures (below 32°F), the carburetor fuel mixture
may need to be adjusted for best engine performance.

OPERATION
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).
ADJUST WHEELS FOR CULTIVATING
(See Figs. 16 and 17)
•
Place blocks under right hand side of tiller and remove
hairpin clip and clevis pin from right hand wheel.
•
Move wheel outward approximately 1 inch (2.5 cm)
until hole in inner wheel hub lines up with inner hole
in axle.
If the tiller is unusually overloaded or jammed, the shear
pins are designed to break before internal damage occurs
to the transmission.
•
•
Replace clevis pin and hairpin clip on inside of wheel
and remove blocks.
Repeat preceding steps on left hand side.
•
If shear pin(s) break, replace only with those shown in
the Repair Parts section of this manual.
CULTIVATING
NOTE: In extremely rough conditions and while cultivat-
ing, the wheels should be moved outward on the axle for
increased stability.
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.
OUTER VIEW OF TIRE
•
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).

SERVICE AND ADJUSTMENTS
•
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 (9 cm), they should be replaced
or straightened as necessary.
New tines should be assembled as shown in Fig.
28. Sharpened tine edges will rotate rearward from
above.
TINE REPLACEMENT
(See Figs. 24, 25 and 26)
CAUTION: Tines are sharp. Wear
gloves or other protection when han-
dling 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.

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 damage may occur.
Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable alternative in mini-
mizing 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 stabilizer container.
Run engine at least 10 minutes after adding stabilizer to
allow the stabilizer to reach the carburetor. Do not drain
the gas tank and carburetor if using fuel stabilizer.
