TINE OPERATION (See Fig. 5)  
AROUND THEYARD  
Squeeze tine control to handle.  
Tip depth stake forward until it is held by the stake  
spring.  
TILLING  
Push tiller handles down, raising tines off the ground.  
Push or pull tiller to desired location.  
The speed and depth of tilling is regulated by the position  
of the depth stake and wheel height.  
AROUND TOWN  
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.  
Disconnect spark plug wire.  
Drain fuel tank.  
Transport in upright position to prevent oil leakage.

OPERATION  
BEFORE STARTING ENGINE  
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.  
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.  
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-  
imatecapacityseePRODUCTSPECIFICATIONSon  
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.  
TO START ENGINE (See Fig. 8)  
CAUTION: Keep drive control bar in  
“DISENGAGED” position when start-  
ing 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.  
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 en-  
gine 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. Repeat if neces-  
sary.  
If engine fires but does not start, move choke control  
to half choke position. Pull recoil 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.  
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(below32°F),thecarburetorfuelmixturemay  
need to be adjusted for best engine performance. See “TO  
ADJUST CARBURETOR” in the Service and Adjustments  
section of this manual.  
NOTE: If engine does not start, see troubleshooting  
points.  
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.  
IMPORTANT: WHEN OPERATING IN TEMPERATURES  
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE

OPERATION  
You will find tilling much easier if you leave a row un-  
SPARK  
PLUG  
tilled 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.  
THROTTLE  
CONTROL  
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.

FIG. 9  
CULTIVATING  
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 up-  
per layer of soil crust will help retain moisture in the soil.  
Best digging depth is 1" to 3" (2.5-7.5 cm).  
TILLING HINTS  
CAUTION: Untilyouareaccustomedto  
handlingyourtiller,startactualelduse  
with throttle in slow position (mid-way  
between “FAST” and “IDLE”).  
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.  
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).  
• 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).  
A properly adjusted tiller will dig with little effort from the  
operator.  
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.

Service aircleanercartridgeeverytwenty-fivehours, more  
often if engine is used in very dusty conditions.  
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.  
Loosen air cleaner screws, one on each side of  
cover.  
Remove air cleaner cover.  
Carefully remove air cleaner cartridge. Be careful. Do  
not allow dirt or debris to fall into carburetor.  
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.  
Clean by tapping gently on a flat surface.  
If very dirty or damaged, replace cartridge.  
Clean and replace cover. Tighten screws securely.  
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.  
CAUTION: Petroleumsolvents,suchas  
kerosene, are not to be used to clean  
cartridge.Theymaycausedeterioration  
of the cartridge. Do not oil cartridge.  
Do not use pressurized air to clean or  
dry cartridge.  
TO CHANGE ENGINE OIL (See Figs. 11 and 12)

preset at the factory and adjustment should not be nec-  
essary. However, minor adjustments may be required to  
compensate for differences in fuel, temperature, altitude or  
load. If the carburetor does need adjustment, see engine  
manual.

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.  
TILLER  
Pull starter handle slowly several times to distribute  
oil.  
Replace with new spark plug.  
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.  
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.  
Touch up all rusted or chipped paint surfaces; sand  
lightly before painting.

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.
