Safe Operation Practices for Cultivator
WARNING: Look for this symbol to point out important safety precautions.
It means: “Attention! Become Alert! Your Safety Is Involved.”
WARNING: To prevent acciden-
tal starting when setting–up,
transporting, adjusting or mak-
ing repairs, always disconnect spark
plug wire and put wire where it cannot
contact the spark plug .
IMPORTANT: Safety standards require opera-
tor presence controls to minimize the risk of in-
jury. Your cultivator is equipped with such
controls. Do not attempt to defeat the function
of the operator presence control under any cir-
cumstances.
Before Use
S Read the owner’s manual carefully. Be
thoroughly familiar with the controls and
the proper use of the cultivator. Know how
to stop the cultivator and disengage the
controls quickly.
S Do not operate the cultivator without wear-
ing adequate outer garments. Wear foot-
wear that will improve footing on slippery
surfaces.
S Keep the area of operation clear of all per-
sons, particularly small children and pets.
S Thoroughly inspect the area where the cul-
tivator is to be used and remove all foreign
objects.
S Keep in mind that the operator or user is
responsible for accidents or hazards occur-
ring to other people, their property, and
themselves.
S Disengage all clutches and shift into neu-
tral before starting the engine (motor).
Fuel Safety
S Handle fuel with care; it is highly flam-
mable.
S Use an approved container.
S Check fuel supply before each use, allow-
ing space for expansion as the heat of the
engine and/or sun can cause fuel to ex-
pand.
S Fill fuel tank outdoors with extreme care.
Do not smoke while refueling. Never fill fuel
tank indoors. Replace fuel tank cap se-
curely and wipe up spilled fuel.
S If fuel is spilled, do not attempt to start the
engine but move the machine away from
the area of spillage and avoid creating any
source of ignition until fuel vapors have dis-
sipated.
S Never remove the fuel tank cap or add fuel
to a running or hot engine.
S Never store fuel or cultivator with fuel in the
tank inside a building where fumes may
reach an open flame.
Operating Safety
S Never allow children or young teenagers to
operate the cultivator. Keep them away
while it is operating. Never allow adults to
operate the cultivator without proper in-
struction.
S Do not operate this machine if you are tak-
ing drugs or other medication which can
cause drowsiness or affect your ability to
operate this machine.
S Do not use this machine if you are mentally
or physically unable to operate this ma-
chine safely.
S Always wear safety glasses or eye shields
during operation or while performing an
adjustment or repair to protect your eyes
from foreign objects that may be thrown
from the cultivator.
S Do not put hands or feet near or under ro-
tating parts.
S Exercise extreme caution when operating
on or crossing gravel drives, walks, or
roads. Stay alert for hidden hazards or
traffic.
S Exercise caution to avoid slipping or falling.

(such as wheel weights, counterweights,
and the like.
S Never operate the cultivator at high trans-
port speeds on hard or slippery surfaces.
Look behind and use care when backing.
S Never allow bystanders near the cultivator.
S Keep children and pets away while
operating.
S Never operate the cultivator without good
visibility or light.
S Be careful when tilling in hard ground. The
tines may catch in the ground and propel
the tiller forward. If this occurs, let go of the
handlebars and do not restrain the ma-
chine.
S Use extreme care when reversing or pull-
ing the machine towards you.
S Do not change the engine governor set-
tings or overspeed the engine.
S Start the engine or switch on the motor
carefully according to instructions and with
feet well away from the tines.
S Never pick up or carry a machine while the
engine is running.
S Do not run the engine indoors. The ex-
haust fumes are dangerous, containing
CARBON MONOXIDE, an ODORLESS
and DEADLY GAS.
S Take all possible precautions when leaving
the cultivator unattended. Stop the engine,
and if equipped, remove the key.
S Do not overload the cultivator capacity by
attempting to till too deep at too fast a rate.
Safe Storage
S Always refer to the owner’s manual instruc-
tions for important details if the cultivator is
to be stored for an extended period.
S Never store the cultivator with fuel in the
fuel tank inside a building where ignition
sources are present such as water and
space heaters, clothes dryers, and the like.
Allow the engine to cool before storing in
any enclosure.
S If the fuel tank has to be drained, do this
outdoors.
S Keep the cultivator in safe working condi-
tion. Check all fasteners at frequent inter-
vals for proper tightness.
Repair / Adjustments Safety
S After striking a foreign object, stop the en-
gine. Remove the wire from the spark plug,
and keep the wire away from the plug to
prevent accidental starting. Thoroughly in-
spect the cultivator for any damage, and
repair the damage before restarting and
operating it.
S If cultivator should start to vibrate abnor-
mally, stop engine and check immediately
for the cause. Vibration is generally a warn-
ing of trouble.
S Stop the engine whenever you leave the
operating position. Also, disconnect the
spark plug wire before unclogging the tines
and when making any repairs, adjust-
ments, or inspections.
S When cleaning, repairing, or inspecting,
shut off the engine and make certain all
moving parts have stopped.
S Never attempt to make any adjustments
while the engine is running except when
specifically recommended by the manufac-
turer.

HOW TO
OPERATE THE CULTIVATOR
1. Start the engine. See “How To Start The
Engine”.
2. Tilt the unit back on the depth stake or
depth rod until the tines are off the
ground. Squeeze the throttle control all
the way up against the hand grip. The
engine is governor controlled and must
be run at full throttle while tilling.
3. Hold the handle firmly and slowly tilt the
unit forward to begin the tilling action.
4. As the tines begin to make contact with
the ground, hold back on the handles so
that the tines will dig into the soil and not
ride forward over the ground.
5. Avoid tilling soil that is too dry as it will
pulverize and produce a dust that will not
hold water. Also, tilling soil that is too wet
will be hard on the machine and produce
unsatisfactory clods.
6. Lowering the depth stake will slow the
cultivator and make it till deeper. Raising
the depth bar will allow it to move faster
and till more shallow. See “How To Set
The Depth Stake or Depth Rod”.
WARNING: Keep away from the
rotating tines. Rotating tines
can cause injury.

BEFORE STARTING THE ENGINE
How To Prepare The Engine
WARNING: Always use a safety
fuel container. Do not smoke
when adding the fuel mixture to
the engine. When inside an enclosure,
do not fill the fuel tank. Before you add
the fuel mixture, stop the engine. Let the
engine cool for several minutes.
How To Mix The Fuel Mixture
The two cycle engine, used on this cultivator,
requires a mixture of gasoline and oil for lu-
brication of the bearings and other moving
parts. The correct fuel mixture ratio is 24:1
(5.3 oz. oil per one gallon of gas – see the
Fuel Mixture Chart). Gasoline and oil must
be pre–mixed in a clean gasoline container.
Always use fresh, clean, unleaded gasoline.
Mix gasoline and oil as follows:
1. Pour one (1) U.S. quart of fresh, clean,
unleaded automotive gasoline into a one
gallon size gasoline container.
2. Add 5.3 ounces of clean, high quality,
two–cycle oil to the gasoline container.
IMPORTANT: Do not use outboard mo-
tor oil or multi–viscosity oils,such as
10W–30 or 10W–40.
3. Install the fuel cap onto the gasoline con-
tainer. Vigorously shake the gasoline
container to mix the oil with the gasoline.
4. Add an additional three (3) U.S. quarts of
gasoline to the gallon container. Again
shake the gasoline container.
5. This completes the gasoline mixing pro-
cedure. The gasoline can now be added
to the fuel tank.

CULTIVATING TIPS
S Tilling is digging in, turning over and
breaking up packed soil before planting.
Loose unpacked soil helps root growth.
Best tilling depth is 4 to 6 inches. A tiller
will also clear the soil of unwanted vege-
tation. The decomposition of this vegeta-
tion 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.
S Avoid tilling soil that is too dry as it will
pulverize and produce a dust that will not
hold water. Also, tilling soil that is too wet
will produce unsatisfactory clods.
S Better growth will be obtained if an area
is tilled properly and used soon after till-
ing to preserve the moisture content.
S The depth stake (on the back of the culti-
vator) serves a dual purpose. It helps
regulate the depth of the cut and also
acts as a brake to help the operator con-
trol the speed of the cultivator.
S Lowering the depth stake will slow the
cultivator and make it till deeper. Raising
the depth stake will allow it to move fast-
er and till more shallow.
S If the cultivator stops forward motion and
tries to dig deeper than necessary, move
the handles from side to side to start for-
ward motion.
S Cultivating is loosening or digging
around growing plants which allows the
plants to flourish.
S When using the cultivator to remove
weeds, it is best to cultivate no deeper
than 1–1/2 inches. Cultivating deeper will
only pull to the surface ungerminated
weed seeds. Raising the depth stake will
allow it to move faster and till more shal-
low.
S When cultivating around plants or close
areas, you may want to remove the out-
side tines. See “Tine Replacement” in
the Service/Adjustments section.
S For better control when cultivation
around delicate plants, turn over the
stake and support the cultivator with the
wheels.
WARNING: Read the Owner’s
manual. Know location and
functions of all controls. Keep
all safety devices and shields in place.
Never allow children or uninstructed
adults to operate cultivator. Shut off en-
gine before unclogging tines or making
repairs. Keep bystanders away from ma-
chine. Keep away from rotating parts
and tines. They can cause injury.
HINTS FOR DEPTH STAKE OR
WHEEL ADJUSTMENT
Light cultivation with moderate
growth
(1 to 2 inches depth)
Adjust the wheels upward to their highest or
next to their highest position. Make sure the
handles are at a comfortable height for oper-
ating the cultivator.
Seed bed preparation
(4 to 6 inches depth)
Use the depth stake. Adjust the depth stake
downward for deeper cultivation.
Heavy soil (4 inch depth or greater)
Remove the depth stake and work the tines
down with a back and forth motion to at least
a depth of 4 inches. Slowly pull the cultivator
backward allowing the soil to feed forward
over the tines.

LUBRICATION
Every 25 hours and/or at the beginning of
each season, make sure the gear box is
filled with lubricant (see Figure 12). Tubes of
gear lubricant are available from most auto-
motive supply stores. Use portable tool
grease such as Lubriplate 630AA (Product
No. 06787, 1–3/4 oz. tube) or Lubriplate
GR–132 (Product No. 15892, 10 oz. tube).
After cleaning and before storage, apply oil
to the tine shaft (see Figure 12).
WARNING: Allow the transmis-
sion to cool before filling with
grease.
1. Remove both left side tines. See “How
To Replace The Tines” in the Service
and Adjustments section.
2. Remove the air vent screw (see
Figure 12).
3. Mount a grease gun onto the grease fit-
ting. Fill the transmission until the
grease begins to come out of the air vent
screw hole.
4. Reinstall the air vent screw.
5. Check the condition of the felt washer
(see Figure 12). Replace the felt wash-
er if it is damaged (see the Repair Parts
section in this manual).
6. Clean and lubricate the tine shaft with a
few drops of oil.
7. Reinstall the left side tines.
8. Remove the right side tines. Check the
felt washer for damage. Clean and oil
the tine shaft. Reinstall the right side
tines.

HOW TO CLEAN THE TINES
Always remove dirt and debris from the culti-
vator after each use. Remove any string,
wire or vegetation that may become lodged
in the mechanism and stop the tines from
rotating.
1. Release the throttle control and move
the on–off switch to the OFF position.
Disconnect the spark plug wire from the
spark plug.
2. While wearing gloves, remove the hair-
pins and clevis pins that secure the tine
assemblies to the shaft (see Figure 13).
Remove the tines from the shaft.
3. Remove any lodged debris from the
shaft and tines. Clean and lubricate the
tine shaft with a few drops of oil.
4. Reassemble the tines on the shaft and
secure with a clevis pin and hairpin.
5. Connect the spark plug wire to the spark
plug.

SPARK PLUG
Check the spark plug every 25 hours. Re-
place the spark plug if the electrodes are
pitted or burned or if the porcelain is
cracked.
1. Make sure the spark plug is clean.
Clean the spark plug by carefully scrap-
ing the electrodes (do not sand blast or
use a wire brush).
2. Check the spark plug gap with a feeler
gauge. See “Product Specifications” for
the correct spark plug gap and replace-
ment spark plug.
3. Before installing the spark plug, coat
the threads lightly with oil for easy re-
moval. Tighten the spark plug to a torque
of 15 foot–pounds.

HOW TO REMOVE AND INSTALL THE TINES
References to the right or left side of the cul-
tivator are from the viewpoint of the opera-
tor’s position behind the unit.
All four tines are different and cannot be in-
terchanged. The tines must be correctly
installed or the cultivator will not function
properly.
To till around plants or in small areas, the
outside tines can be removed to reduce the
tilling width to approximately 7 inches.
WARNING: The tines are self
sharpening and will become
quite sharp from use. Handle
carefully.
The tines will all wear evenly. If the tines are
being replaced because of wear, we recom-
mend that all four tines be replaced at the
same time. To replace the tines, do the fol-
lowing:
Tine Removal
1. Put the on–off switch in the OFF posi-
tion.
2. Disconnect the spark plug wire from the
spark plug.
3. While wearing gloves, remove the hair-
pins and clevis pins that secure the tine
assemblies to the shaft (see Figure 15).
Remove the tines from one side of the
unit.

Tine Installation
1. Clean and lubricate the tine shaft with a
few drops of oil.
2. Place the inside tine on the tine shaft
and reinstall the clevis pin and hairpin.
3. When the tines are properly installed, the
letter R will be visible on the outside of
the right tine (see Figure 16). The letter
L will be visible on the outside of the left
tine.
Figure 16
R
4. Mount the outside tine on the tine shaft
and fasten with the clevis pin and hair-
pin (see Figure 15).
5. The cutting tips on the outside tines all
bend in toward the inside tine. When as-
sembled correctly, the letter R on the
right side, or L on the left side, will be
visible from the outside of the unit.
6. Repeat the above steps on the opposite
side of the unit.
NOTE: Make sure the tines are installed
on the correct side of the unit.

STORAGE
WARNING: Never store the cul
-
tivator indoors with fuel in the
fuel tank. Never store in an en-
closed, poorly ventilated area where
fumes could reach an open flame, a
spark or a pilot light as on a furnace, wa
-
ter heater or clothes dryer.
WARNING: Do not remove gas
-
oline while inside a building,
near a fire, or while you smoke.
Gasoline fumes can cause an explosion
or a fire.
When the cultivator is put in storage for thirty
days or more, follow the steps below to
make sure the cultivator is in good condition
the following season.
Cultivator
S Completely clean the cultivator.
S Remove the tines. Clean and apply oil to
the tine shafts. Mount the tines onto the
tine shafts. See “How To Remove And
Install The Tines” in the Service And Ad-
justments section.
S Loosen the knobs that secure the upper
handle to the lower handle. Carefully fold
the upper handle. Make sure the throttle
cable is not bent. Tighten the knobs.
S The cross piece of the upper handle (be-
tween the lower handles) can now be
used as a carry handle. To store the cul-
tivator up off the floor and out of the way,
the cross piece can also be hooked over
a wall hook.
S Put the cultivator in a building that has
good ventilation.
S Cover the cultivator with a suitable pro-
tective cover that does not retain mois-
ture. Do not use plastic.
IMPORTANT: Never cover the cultivator
while the engine and exhaust areas are
still warm.
NOTE: A yearly checkup or tune–up by a
Authorized Service Center is a good way
to make sure that your cultivator will pro-
vide maximum performance for the next
season.
Engine
IMPORTANT: It is important to prevent
gum deposits from forming in fuel system
parts such as the carburetor, fuel filter,
fuel hose, and tank during storage. Also,
using alcohol–blended fuels (called gaso-
hol, 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 en-
gine while in storage.
To prevent engine damage when the cultiva-
tor is in storage for 30 days or more, follow
the steps below:
S Let the engine run until it is out of gaso-
line.
S Slowly pull the starter handle until you
feel resistance due to compression in
the cylinder, then stop.
S Slowly release the starter rope. This
position will close both the intake and the
exhaust ports and help prevent corrosion
of the piston and cylinder.
