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)

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
imate capacity see “PRODUCT SPECIFICATIONS” on
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.
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.
CAUTION: Fill to within 1/2 inch of top

• 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.

OPERATION
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.
See "TO ADJUST CARBURETOR" in the Service and
Adjustments section of this manual.
NOTE: If engine does not start, see troubleshooting
points.
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 Adjustments
section of this manual.
Soil conditions are important for proper tilling. Tines will
not readily penetrate dry, hard soil which may contribute
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. 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.
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.
TILLING HINTS
CAUTION: Until you are accustomed
A
To help tiller move forward, lift up th_e handles slightly (thus
lifting depth stake out of ground), lo slow down the tiller,
press down on handles.
If you are straining ortiller 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).
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
clearthe 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.
to handling your tiller, start actual field
use with throttle in slow position.
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
rifinth if! 1 "-.f?"
• 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 condition, promoting no further growth of weeds
and grass (See Fig. 10).

GENERAL RECOMMENDATIONS
The warranty on this tiller does not cover items that have
been subjected to operator abuse or negligence. To receive
full value from the warranty, the operator must maintain tiller
as instructed in this manual.
Some adjustments will need to be made periodically to
properly maintain your tiller.
At least once a season, check to see if you should make
any of the adjustments described in the Service and Ad
justments section of this manual.
• Once a year you should replace the spark plug, clean
or replace air filter, and check tines and belts for wear.
A new spark plug and clean air filter assure proper
air-fuel mixture and help your engine run better and
last longer.
