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.
WHEELS (See Fig. 6)

ADD GASOLINE
• Fill fuel tank to bottom of filler neck. Do not overfill.
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 flame.
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE
GAS O LINE TO HELP INSURE GOOD COLD WEATHER
START ING.
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 TINE CONTROL IN “OFF”
PO SI TION WHEN STARTING ENGINE.
When starting engine for the first time or if engine has run
out of fuel, it will take ex tra pulls of the recoil starter to
move fuel from the tank to the engine.
1. Make sure spark plug wire is prop er ly connected.
2. Place the fuel valve to the "ON" position.
3. To start a cold engine, move the choke lever to the
"ON" position.
4. Move the throttle lever away from the "SLOW" position,
about 1/3 of the way toward the "FAST" position.
5. Turn the engine switch to the "ON" position. Pull rope
out slowly until engine reaches start of com pres sion
cy cle (rope will pull slightly harder at this point).
6. Pull recoil starter handle quickly. Do not let starter
handle snap back against starter. Repeat if necessary.
NOTE: IF ENGINE FIRES BUT DOES NOT START, MOVE
CHOKE CONTROL TO HALF CHOKE POSITION. PULL
RECOIL STARTER HANDLE UNTIL ENGINE STARTS.
7. If the choke lever has been moved to the "ON" position
to start the engine, gradually move it to the opposite
position as the engine warms up.
NOTE: A WARM ENGINE REQUIRES LESS
CHOK ING TO START.
8. Move throttle control to desired running position.
9. Allow engine to warm up for a few min utes before
engaging tines.

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 Ad just ments
sec tion of this manual.
TILLING HINTS
CAUTION: Until you are accustomed
to handling your tiller, start ac tu al field
use with throttle in slow position.
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"-6". A tiller will also
clear the soil of unwanted vege ta tion. The de com po si tion
of this vegetable mat ter en rich es the soil. De pend ing
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 difficult 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 find 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 first 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"-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 con di tion, promoting no fur ther growth of weeds
and grass (See Fig. 10).
