Break-In Operation
Perform the following maintenance after the first five (5) hours
of new operation (see the Maintenance & Adjustments Section in
this manual).
1.
2.
Complete the Pre-Start Checklist above on this page.
Put the wheels in the WHEEL DRIVE position by removing
the click pins, sliding the wheel all the way in and reinstalling
the click pin through the wheel hubs and wheel shaft.
3.
4.
Move the Depth Regulator Lever all the way down to the
“transport” position, so that the tines clear the ground.
1.
2.
Change engine oil.
Check for loose or missing hardware on unit. Tighten or
replace as needed.
Release all of the controls on the tiller and refer the Engine
Operator’s Manual for engine starting and stopping
instructions.
3.
Check transmission gear oil level.
11
To adjust the depth stake, pull back on the depth adjustment
bracket (A) and push up or down (B) until the bracket reaches the
desired position, see Figure 5-1, then release the bracket (C).
To Engage Drive & Tines
1.
For forward motion of the wheels and power to the tines pull
the Forward Clutch Bail up against the handlebar. Release
the bail to stop the forward motion of wheels and tines.
To adjust the side shields (if so equipped), remove the wing nuts.
Move the side shield to the desired position and replace the wing
nuts. Tighten securely. See Figure 5-2.
2.
When tilling, relax and let the wheels pull the machine
while the tines dig. Walk behind and a little to one side of
the tiller. Use one hand, yet keep a light — but secure —
grip on the handlebar while keeping your arm loose.
3.
Let the tiller move at its own pace and do not push down
on the handlebars to try and force the tines to dig deeper
— this takes weight off the wheels and reduces traction.
WARNING! Do not push down on the handlebars
to try to make the tiller till more deeply. This
prevents the wheels from holding the tiller back and
can allow the tines to rapidly propel the tiller
forward, which could result in loss of control,
property damage, or personal injury.
4.
To stop/disengage the drive/tines release the forward
clutch bail.
To move in reverse:
1.
Release the forward Clutch Bail. Then lift the handlebar
until the tines are off the ground.
2.
Pull back on the Reverse Lever, and walk backwards with
the machine
NOTE: In reverse mode, the tines will reverse rotation.
Figure 5-2
3.
If longer distances need to be covered in reverse, shut off
the engine, then place the two wheels in FREEWHEEL.
Adjusting the Handle Height
The handle should be adjusted so that when the tiller is digging
3-4” into the soil, the handle falls to about waste-high. To adjust
the handle, simply loosen the handle adjustment crank, move
the handle to the desired height and retighten the adjustment
crank. See Figure 5-3.
Turning the Tiller
1.
2.
3.
Practice turning the tiller in a level, open area. Be very
careful to keep your feet and legs away from the tines.
To begin a turn, lift the handlebars until the tines are out of the
ground and the engine and tines are balanced over the wheels.
With the tiller balanced, push sideways on the handlebar to
steer in the direction of the turn. After turning, slowly lower
the tines into the soil to resume tilling.
Setting The Depth
Tilling depth is controlled by the depth stake which can be
adjusted to five different settings. Adjust the side shields as you
adjust the depth stake.
WARNING: Be certain the spark plug wire is
disconnected and grounded against the engine
when performing any adjustments.
•
•
When using the tiller for the first time, use the second
adjustment hole from the top (1” of tilling depth).
When breaking up sod and for shallow cultivation, use the
setting which gives 1” of tilling depth (second hole from
the top). Place the side shields in their lowest position.
•
•
For further depth, raise the depth stake and side shields
and also make one or two more passes over the area.
Figure 5-3
When tilling loose soil, the depth stake may be raised to its
highest position (use bottom adjustment hole) to give the
deepest tilling depth. Raise the side shields to the highest
position.
•
To transport tiller, lower the depth stake (use top
adjustment hole).

Suggested Tilling Patterns
Tilling Tips & Techniques
•
When preparing a seedbed, go over the same path twice in
the first row, then overlap one-half the tiller width on the
rest of the passes. See Figure 5-5.
Tilling Depth
WARNING! Before tilling, contact your telephone or
utilities company and inquire if underground equipment/
lines are used on your property. Do not till near buried
electric cables, telephone lines, pipes or hoses.
•
This is a CRT (counter-rotating tine) tiller. As the
wheels pull forward, the tines rotate backward. This creates
an “uppercut” tine action which digs deeply, uprooting soil
and weeds. Don’t overload the engine, but dig as deeply as
possible on each pass. On later passes, the wheels may tend
to spin in the soft dirt. Help them along by lifting up slightly
on the handlebar (one hand, palm up, works most easily).
•
•
Avoid the temptation to push down on the handlebars in an
attempt to force the tiller to dig deeper. Doing so takes the
weight off the powered wheels, causing them to lose traction.
Without the wheels to hold the tiller back, the tines will
attempt to propel the tiller backward, towards the operator.
When cultivating (breaking up the surface soil around the
plants to destroy weeds, see Figure 5-4), adjust the tines to
dig only 1” to 2” deep. Using the shallow tilling depth helps
prevent injury to the plants whose roots often grow close to
the surface. If needed, lift up on the handlebars slightly to
prevent the tines from digging too deeply. (Cultivating on a
regular basis not only eliminates weeds, it also loosens and
aerates the soil for better moisture absorption and faster plant
growth.) Watering the garden area a few days prior to tilling
will make tilling easier, as will letting the newly worked soil set
for a day or two before making a final, deep tilling pass.
Figure 5-5
•
When finished in one direction, make a second pass at a
right angle, as shown in Figure 5-6. Overlap each pass for
the best results (in very hard ground, it may take three or
four passes to thoroughly pulverize the soil.)
Figure 5-4
Figure 5-6
Choosing Correct Wheel & Tine Speeds
With experience, you will find the tilling depth and tilling speed
combination that is best for your garden. Set the engine throttle
lever at a speed to give the engine adequate power and yet
allow it to operate at the slowest possible speed until you have
achieved the maximum tilling depth you desire. Faster engine
speeds may be desirable when making final passes through the
seedbed or when cultivating. Selection of the correct engine
speed, in relation to the tilling depth, will ensure a sufficient
power level to do the job without causing the engine to labor.
Section 5 — operation
13
•
If the garden size will not permit lengthwise and then
crosswise tilling, then overlap the first pass by one-half a
tiller width, followed by successive passes at one-quarter
width. See Figure 5-7.
Terrace Gardening

tiller, always keep the uphill wheel in the soft, newly tilled
soil. Do not till the last 12” or more of the downhill outside
edge of each terrace. This untilled strip helps prevent the
terraces from breaking apart and washing downhill. It also
provides a walking path between the rows.
WARNING! Do not operate the tiller on a slope too
steep for safe operation. Till slowly and be sure you
have good footing. Never permit the tiller to
freewheel down slopes. Failure to follow this
warning could result in personal injury.
1.
2.
Till only on moderate slopes, never on steep ground where
the footing is difficult.
Clearing the Tines
•
Tilling up and down slopes is recommended over terracing.
Tilling vertically on a slope allows maximum planting area
and also leaves room for cultivating.
The tines have a self-clearing action which eliminates most
of the tangling of debris. However, occasionally dry grass,
stringy stalks or tough vines may become tangled. Follow
these procedures to help avoid tangling and to clear the
tines, if necessary.
NOTE: When tilling on slopes, be sure the correct oil level
is maintained in the engine (check every one-half hour
of operation). The incline of the slope will cause the oil to
slant away from its normal level and this can starve engine
parts of required lubrication. Keep the motor oil level at the
full point at all times.
•
•
To reduce tangling, set the depth regulator deep enough to
get maximum “chopping” action as the tines chop the material
against the ground. Also, try to till under crop residues or cover
crops while they are green, moist and tender.
Tilling Up and Down a Slope
While tilling, try swaying the handlebars from side to side
(about 6” to 12”). This “fishtailing” action often clears the
tines of debris.
1.
To keep soil erosion to a minimum, be sure to add enough
organic matter to the soil so that it has good moisture-
holding texture and try to avoid leaving footprints or wheel
marks.
WARNING! Before clearing the tines by hand, stop
the engine, allow all moving parts to stop and
disconnect the spark plug wire. Failure to follow this
warning could result in personal injury.
2.
When tilling vertically, try to make the first pass uphill
as the tiller digs more deeply going uphill than it does
downhill. In soft soil or weeds, you may have to lift the
handlebars slightly while going uphill. When going
downhill, overlap the first pass by about one-half the width
of the tiller.
Section 5— operation

Loading & Unloading the Tiller
WARNING! Loading and unloading the tiller into a
vehicle is potentially hazardous and doing so is not
recommended unless absolutely necessary, as this
could result in personal injury or property damage.
However, if you must load or unload the tiller, follow the
guidelines given next.
•
Before loading or unloading the tiller, stop the engine, wait
for all parts to stop moving, disconnect the spark plug wire
and let the engine and muffler cool.
•
•
The tiller is too heavy and bulky to be safely lifted by one
person. Two or more people should share the load.
Use sturdy ramps and manually — with the engine shut
off — roll the tiller into and out of the vehicle. Two or more
people are needed to do this.
•
The ramps must be strong enough to support the
combined weight of the tiller and any handlers. The ramps
should provide good traction to prevent slipping; they
should also have side rails to guide the tiller along the
ramps; and they should have a locking device to secure
them to the vehicle.
•
•
The handlers should wear sturdy footwear that will help to
prevent slipping.
Position the loading vehicle so that the ramp angle is as flat
as possible (the less incline to the ramp, the better). Turn
the vehicle’s engine off and apply the parking brake.
•
•
When going up the ramps, stand in the normal operating
position and push the tiller ahead of you. Have a person at
each side to turn the wheels.
When going down the ramps, walk backward with the tiller
following you. Keep alert for any obstacles behind you.
Position a person at each wheel to control the speed of the
tiller. Never go down the ramps tiller-first, as the tiller could
tip forward.
•
•
Place wooden blocks on the downhill side of the wheels
if you need to stop the tiller from rolling down the ramp.
Also, use the blocks to temporarily keep the tiller in place
on the ramps (if necessary), and to chock the wheels in
place after the tiller is in the vehicle.
After loading the tiller, prevent it from rolling by engaging
the wheels in the WHEEL DRIVE position. Chock the wheels
with blocks and securely tie the tiller down.

With the tiller on level ground, pull the Depth Regulator
Lever all the way up.
WARNING! Before inspecting, cleaning or servicing
the machine, shut off the engine, wait for all moving
parts to come to a complete stop, disconnect the
spark plug wire and move the wire away from the
spark plug. Failure to follow these instructions can
result in serious personal injury or property damage.
Remove the oil fill plug from the transmission housing and
look inside the oil fill hole to locate the main drive shaft
situated below the hole. See Figure 6-1.
Maintenance
Engine
Refer to the Engine Operator’s Manual for all engine maintenance.
Tire Pressure
Check the air pressure in both tires. The air pressure should
be between 15-20 PSI. Keep both tires equally inflated to help
prevent machine from pulling to one side.
Hardware
Check for loose or missing hardware after every 10 operating hours
and tighten or replace — as needed — before reusing the tiller
Be sure to check the screws underneath the tiller hood that
secure the transmission cover and the Depth Regulator Lever to
the transmission.
Transmission Gear Oil
Check the transmission gear oil after every 30 hours of operation
or whenever you notice any oil leak. Operating the tiller when
the transmission is low on oil can result in severe damage.
Figure 6-1
4.
5.
The gear oil level is correct if the gear oil is approximately
halfway up the side of the main drive shaft.
To Check the Transmission Gear Oil Level:
If the gear oil level is low, add gear oil as described next. If
the gear oil level is okay, securely replace the oil fill plug.
1.
Check the gear oil level when the transmission is cool. Gear
oil will expand in warm operating temperatures and this
expansion will provide an incorrect oil level reading.
16
6.
If adding only a few ounces of gear oil, use API rated GL-4
or GL-5 gear oil having a viscosity of SAE 140, SAE 85W-140
or SAE 80W-90. If refilling an empty transmission, use only
GL-4 gear oil having a viscosity of SAE 85W-140 or SAE 140.
Off-Season Storage
When the tiller won’t be used for an extended period, prepare it
for storage as follows:
1.
2.
Clean the tiller and engine.
7.
While checking frequently to avoid overfilling, slowly add
gear oil into the oil fill hole until it reaches the halfway
point on the drive shaft.
Do routine tiller lubrication and check for loose parts and
hardware.
8.
Securely replace the oil fill plug.
3.
4.
Change the engine oil and filter following the instructions
provided in the engine manual packed with this manual.
Lubrication
WARNING! Never store the tiller with fuel in the
tank indoors or in poorly ventilated enclosures, where
fuel fumes may reach an open flame, spark or pilot
light as on a furnace, water heater, clothes dryer, etc.
After every 10 operating hours, oil or grease the lubrication
points shown in Figure 6-2 and described below.
If storing the tiller for 30 days or more:
a. To prevent gum deposits from forming inside
the engine’s carburetor and causing possible
malfunction of the engine, the fuel system must be
either completely emptied, or the gasoline must be
treated with a stabilizer to prevent deterioration.
Depth Regulator Lever
Handlebar Hardware
WARNING! Fuel left in the fuel tank deteriorates
and will cause serious starting problems.
b. Using a fuel stabilizer such as STA-BIL® for storage
between 30 and 90 days:
•
•
Read the product manufacturer’s instructions
and recommendations.
Wheel Shaft
Tine Shaft
Add to clean, fresh gasoline the correct
amount of stabilizer for the capacity
(approximately 3 gallons) of the fuel system.
•
Fill the fuel tank with treated fuel and run the
engine for 2-3 minutes to get stabilized fuel
into the carburetor.
Figure 6-2
Use clean lubricating oil (#30 weight motor oil is suitable)
and clean general purpose grease (grease containing a metal
lubricant is preferred, if available).
c. Emptying the fuel system for storage of more than
90 days:
•
Remove the wheels, clean the wheel shaft and apply a thin
coating of grease.
•
•
•
Prior to putting the tiller in storage, monitor
fuel consumption with the goal of running
the fuel tank empty.
•
•
Grease the back, front and sides of the depth regulator lever.
Remove the tines and clean the tine shaft. Use a file or
sandpaper to gently remove any rust, burrs or rough spots
(especially around the holes in the shaft). Apply grease to
the ends of the shaft before installing the tines.
Run the engine until it begins to stall. Use the
choke to keep the engine running until all fuel
in the carburetor has been exhausted.
Referring to the engine manual, drain the fuel
from the carburetor bowl.
•
Oil the threads on the handlebar height adjustment screws
and the handlebar attaching screws.
4.
5.
Store the tiller in a clean, dry area.
Never store the tiller with fuel in the fuel tank in an
enclosed area where gas fumes could reach an open flame
or spark, or where ignition sources are present (space
heaters, hot water heaters, furnaces, etc.).

Remove the idler bracket extension spring, as pointed out in
Figure 7-3. It is recommended to use a pair of needle-nosed
pliers, and grab the spring by the end that hooks over the
frame. Simply grab it and pull it away from the frame, then
up wards and carefully relieve the tension of the spring.
Belt Replacement
If the drive or reverse belts need to be replaced, it is best to replace
both belts at the same time. Use only a factory-authorized belt as an
“over- the-counter” belt may not perform satisfactorily. The procedure
requires average mechanical ability and commonly available tools.
To replace the drive and reverse belts, follow these steps:
1.
Make sure the tiller is on a flat surface, with the engine
turned off and the spark plug wire unplugged and
grounded to prevent unintended firing of the engine.

NOTE: The tine assembly moves in a counter-rotating
motion with the sharp edges of the tines positioned to
enter the soil first when counter-rotating. Note this position
of the tines for reinstallation of the new tine assemblies.
3.
To remove a tine assembly, simply remove the cotter pin
securing the clevis pin as seen in Figure 7-6. Remove the
clevis pin and slide the assembly to the outside of the unit
and off of the tine shaft.

9.
Reinstall the transmission drive pulley with the new belts.
Cotter Pin
Reassemble the tiller in the reverse order in which it was
disassembled.
NOTE: When reinstalling the belt cover, be sure to engage the
bail and hold it so that the drive belt is tight before attempting
to reinstall the belt cover. This will enable the belt to fall under
the belt keeping mechanism built into the belt cover. Failure
to do so could damage the belt and/or belt cover.
Figure 7-6
4.
5.
Before reinstalling the tine assembly, inspect the tine
shaft for rust, rough spots or burrs. Lightly file or sand, as
needed. Apply a thin coat of grease to the shaft.
Tines
The tines will wear with use and should be inspected at the
beginning of each tilling season and after every 30 operating
hours. The tines can be replaced. Refer to the Illustrated Parts List
manual for part numbers and ordering instructions.
Install each tine assembly so that the cutting (sharp) edge
of the tines will enter the soil first when the tiller moves
forward. Keep in mind that these tines are counter rotating,
so secure the tine assembly to the tine shaft using the
clevis pin and internal cotter pin.
Tine Inspection
With use, the tines will become shorter, narrower and pointed.
Badly worn tines will result in a loss of tilling depth, and reduced
effectiveness when chopping up and turning under organic
matter.
Change Transmission Gear Oil
NOTE: The transmission gear oil does not need to be changed
unless it has been contaminated with dirt, sand or metal
particles.
See an authorized service dealer to have the transmission gear oil
changed. Refer to the phone numbers on page 2 of this manual
to locate the nearest service dealer.
