OPERATION  
The operation of any tiller can result in foreign objects thrown into the eyes, which can  
result in severe eye damage. Always wear safety glasses or eye shields before starting  
your tiller and while tilling. We recommend a wide vision safety mask for over spectacles  
or standard safety glasses.  
DEPTH STAKE (See Fig. 10)  
The depth stake can be raised or lowered to allow you more  
versatile tilling and cultivating, or to more easily transport  
your tiller.

OUTER SIDE SHIELDS (See Fig. 11)  
Fill fuel tank to bottom of filler neck. Do not overfill.  
The back edges of the outer side shields are slotted so  
that the shields can be raised for deep tilling and lowered  
for shallow tilling to protect small plants from being buried.  
Loosen nut “A” in slot and nut “B”. Move shield to desired  
position (both sides). Retighten nuts.  
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: 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.  
CAUTION: Beforeliftingortransporting,  
allow tiller engine and muffler to cool.  
Disconnect spark plug wire. Drain  
gasoline from fuel tank.  
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.  
Place shift lever indicator in “F” (forward) position for  
transporting.  
Hold the drive control bar against the handle to start  
tiller movement. Tines will not turn.  
Move throttle control to desired speed.  
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  
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.  
AROUND TOWN  
Disconnect spark plug wire.  
Drain fuel tank.  
Transport in upright position to prevent oil leakage.  
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)  
The engine in your unit has been shipped, from the  
factory, already filled with SAE 30 summer weight oil.  
With engine level, clean area around oil filler plug and  
remove plug.  
Engineoilshouldbetopointofoverflowingwhenengine  
is level. For approximate capacity see “PRODUCT  
SPECIFICATIONS” on page 3 of this manual. All oil  
must meet A.P.I. Service Classification SF-SJ.  
For cold weather operation you should change oil for  
easier starting (See oil viscosity chart in the Mainte-  
nance section of this manual).  
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.  
Make sure spark plug wire is properly connected.  
Move shift lever indicator to “N” (neutral) position.  
To change engine oil, see the Maintenance section in  
this manual.

Turn engine switch to “ON” 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 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.  
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.

section of sod or hard ground, apply upward pressure  
on handle or lower the depth stake.  
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.

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.  
CHOKE CONTROL

PLUG  
THROTTLE  
CONTROL  
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).

TILLING HINTS  
CAUTION: Untilyouareaccustomedto

with throttle in slow position (mid-way  
between “FAST” and “IDLE”).  
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.  
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.  
FIG. 15  
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.

MUFFLER  
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.  
Do not operate tiller without muffler. Do not tamper with  
exhaustsystem.Damagedmufflersorsparkarresterscould  
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.  
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.  
SPARK PLUG  
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.  
Replace spark plugs at the beginning of each tilling sea-  
son or after every 50 hours of use, whichever comes first.  
Spark plug type and gap setting is shown in “PRODUCT  
SPECIFICATIONS” on page 3 of this manual.  
TO CHANGE ENGINE OIL (See Figs. 16 and 17)  
Determine temperature range expected before oil change.  
All oil must meet API service classification SF-SJ.  
TRANSMISSION  
Once a season, lubricate the right hand side gear case  
grease fitting with 1 oz. of EP #1 Grease.  
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.  
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  
fi lter and carburetor are covered to keep water out. Water  
in engine will shorten the useful life of your tiller.  
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.  
Clean engine, wheels, finish, etc. of all foreign mat-  
ter.  
Remove oil filler plug. Be careful not to allow dirt to  
enter the engine.  
Refillenginewithoil. SeeCHECKENGINEOILLEVEL”  
in the Operation section of this manual.  
Keep finished surfaces and wheels free of all gasoline,  
oil, etc.

TO REPLACE GROUND DRIVE BELT  
(See Fig. 21)  
(See Fig. 21)  
For proper belt tension, the extension spring should  
have about 5/8 inch stretch when drive control bar is in  
“ENGAGED” position. This tension can be attained as  
follows:  
Remove belt guard (SeeTO REMOVE BELT GUARD”  
in this section of this manual).  
Remove old belt by slipping off engine pulley first then  
remove from transmission pulley.  
Place new belt in groove of transmission pulley and  
into engine pulley. BELT MUST BE IN GROOVE ON  
TOP OF IDLER PULLEY. NOTE POSITION OF BELT  
TO GUIDES.  
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 stretch is obtained  
while the drive control bar is engaged.  
Check belt adjustment as described below.  
Replace belt guard.  
Reposition wheel and replace clevis pin and hairpin

SERVICE AND ADJUSTMENTS  
To maintain the superb tilling performance of this  
TINE REPLACEMENT  
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.  
(See Figs. 22, 23, and 24)  
CAUTION: Tines are sharp. Wear  
gloves or other protection when han-  
dling tines.  
New tines should be assembled as shown in Fig.  
26. Sharpened tine edges will rotate rearward from  
above.  
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.

CARBURETOR  
Thecarburetorhasbeenpresetatthefactoryandadjustment  
should not be necessary. However, engine performance  
can be affected by differences in fuel, temperature, altitude  
or load. If the carburetor does need adjustment, contact  
your nearest authorized service center/department.

WARNING: Never store the tiller with  
gasoline in the tank inside a building  
where fumes may reach an open flame  
orspark. Allowtheenginetocoolbefore  
storing in any enclosure.  
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.  
TILLER  
Cleanentiretiller(SeeCLEANINGintheMaintenance  
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.  
OTHER  
Do not store gasoline from one season to an-  
other.  
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.
