1. Carefully read this Operator’s Manual, the separate
Engine Owner/Operator’s Manual, and any ot her
literature you may receive. Be thoroughly familiar
with the controls and the proper use of the tiller and
its engine. Know how to stop the unit and
disengage the controls quickly.

2. Never allow children to operate the tiller. Never
allow adults to operate the tiller without proper
instruction.

3. Keep the area of operation clear of all persons,
particularly children and pets.

4. Keep in mind that the operator or user is
responsible for accidents or hazards occurring to
other people, their property, and themselve s.

Preparation

1. Thoroughly inspect the area where the tiller is to be
used and remove all foreign objects.

2. Be sure all control levers are released before
starting the engine.

3. Do not operate the tiller without wearing adequate
outer garments. Avoid loose garments or jewe lry
that could get caught in moving parts.

4. Do not operate the tiller when barefoot or wearing
sandals, sneakers, or light footwear. Wear
protective footwear that will improve footing on
slippery surfaces.

5. Do not till near underground electric cables,
telephone lines, pipes or hoses. If in doubt, contact
your telephone or utility company.

6. Never make adjustments when engine is running
(unless recommended by the Engine
manufacturer).

WARNING: Handle fuel with care; it is highly flammable

and its vapors are explosive. Take the following precautions:

a. Store fuel in containers specifically de signed

for this purpose.

b. The gas cap shall never be removed or fuel

added while the engine is running. Allow the
engine to cool for several m inutes before
adding fuel.

c. Keep matches, cigarettes, cigars, pipes,

open flames, and sparks away from the fuel
tank and fuel container.

d. Fill fuel tank outdoors with extreme care.

Never fill fuel tank indoors. Use a funnel or
spout to prevent spillage.

e. Replace all fuel tank and container ca ps

securely.

f. 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
dissipated.

Operation

1. Do not put hands or feet near or under rotating
parts.

2. Exercise extreme caution when on or crossing
gravel drives, walks, or roads. Stay alert for hid den
hazards or traffic. Do not carry passengers.

3. After striking a foreign object, stop th e engine,
thoroughly inspect the machine for an y damage,
and repair the damage before rest arting and
operating the machine.

4. Exercise caution to avoid slipping or falling.

5. If the unit should start to vibrate abnormally, stop the

10. Never use the tiller unless proper guards, pla te s , o r
other safety protective devices are in place.

11. Do not run engine in an enclosed area. Engine
exhaust contains carbon monoxide gas, a deadly
poison that is odorless, colorless, and tast eless.

12. Keep children and pets away.

13. Be aware that the tiller may unexpectedly bounce
upward or jump backward if the tines should strike
extremely hard packed soil, frozen ground, or
buried obstacles like large stones, roots, or stumps.
If in doubt about the tilling conditions, always use
the following operating precautions to assist you in
maintaining control of the tiller:

a. Walk behind and to one side of the tiller,

using one hand on the handlebars. Relax

your arm, but use a secure hand grip.
b. Use slower engine speeds.
c. Clear the tilling area of all large stones, roots

and other debris.
d. Avoid using downward pressure on

handlebars. If need be, use slight upward

pressure to keep the tines from digging too

deeply.
e. Before contacting hard packed soil at the e nd

of a row, reduce engine speed and lift

handlebars to raise tines out of the soil.
f. In an emergency, stop tines and wheels by

releasing the Wheel Engagement Handle.

Do not attempt to restrain the tiller.

15. Do not overload the tiller’s capacity by attempting to

1. Check unit for loose or missing hardware. Service as
required.

2. Check motor oil level. Refer to separate Briggs &
Stratton Operator/Owner Manual.

3. Check that all safety guards and covers are in place.

4. Check air cleaner and engine cooling system. Refer
to separate Briggs & Stratton Operator/Owner
Manual.

5. Select a tine direction (Refer to Tine Direction Selector
on page 10).

6. Fill the fuel tank with gasoline as instructed in the
separate Briggs & Stratton Operator/Owner Manual
packed with your tiller. Read instructions carefully.

WARNING: Gasoline is highly flammable and

its vapors are explosive. Follow gasoline safety
rules found on Page 3 in this manual, an d in the
separate Briggs & Stratton Operator/Owner
Manual. Failure to follow gasoline safety
instructions can result in serious personal injury
and property damage.

• Grasp the starter handle and pull the rope out slowly

Operating the Tiller

WARNING: Before tilling new ground,

contact your telephone and utilities company to
inquire if underground lines are on the property.

The following pages provide guidelines to using your tiller
effectively and safely in various gardening applications.
Be sure to read Tilling Tips & Techniques in this Section
before you actually put the tines into the soil.

1. Follow the Pre-Start Checklist on page 11. Be sure that
the wheel shift lever is in the NEUTRAL position.

2. Start the engine and allow it to warm up for a few
minutes. Move the throttle control into the FAST
speed setting.

IMPORTANT:

the FAST (rabbit) position.

3. For forward or reverse motion o f the wheels and no
power to the tines:

NOTE: If you encounter difficulty repositioning the

wheel shift lever from FORWARD or REVERSE into
NEUTRAL or vice-versa, gently rock the tiller (slightly
push-and-pull the handlebar forward and backward) prior
to moving the wheel shift lever. Doing so will help fully
disengage the transmission’s internal drive clut ch.

Always operate the tiller with the throttle in

a. Place the tine engagement lever in the OFF

position.

b. Place the wheel shift lever in either the

FORWARD position or REVERSE position.

c. Close the wheel engagement handle against

the handlebar to cause the wheels to drive. To
stop the wheels, release the wheel
engagement handle.

WARNING: Do not push down on the

handlebar to try to make the tiller till more
deeply. Doing so prevents the wheels from
holding the tiller back and can allow the tines (in
CRT mode) to rapidly propel the tiller backward
toward the operator, which could result in loss of
control, property damage, or personal injury.

• As the tiller moves forward, relax and let the wheels
pull the unit along while the tines dig.

• Walk behind, and a little to one side of the tiller.

• Use a light but secure grip with one hand on the
handlebars, but keep your arm loose.

• Let the tiller move ahead at its own pace. Do not push
down on the handlebar in an attempt to force the tiller
to dig deeper. If necessary, stop the tiller, turn off the
engine and reposition the depth regulator lever to
adjust tilling depth before restarting and operating the
tiller.

5. To turn the tiller around:

a. Practice turning in a level, open area with the

tines not engaged.

b. To start a turn, carefully raise the handlebar

until the engine and tines are balanced over t he
wheels.

c. With the tiller balanced, push sideways on the

handlebar to move the tiller in the direction of
the turn. After completing the turn, slowly lower
the tines into the soil.

Stopping the Tiller and Engine

1. To stop the wheels and tines, r elease /open the wheel

engagement handle.

2. To stop the engine, move the engine throttle lever to

STOP. Refer to Figure 1.

TILLING TIPS & TECHNIQUES

Tilling Depths

WARNING: Before

tilling, contact your
telephone or utilities
company and inquire if
underground equipment or
lines are used on your
property. Do not till near
buried electric cables,
telephone lines, pipes or
hoses

.

• When cultivating (breaking up surface soil around plants to destroy weeds), adjust the tines to dig only 1" to 2" deep. Using shallow tilling
depths helps prevent injury to plants whose roots often grow close to the surface. If needed, lift up on the handlebar 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.

Choosing Correct Tine Depth & Rotation

• Operate the tiller in CRT mode when tilling virgin ground, sod or hard soil.

• Operate the tiller in FRT mode when cultivating or tilling soft ground or previously tilled soil.

IMPORTANT:

When operating the tiller in FRT mode, always lower the depth regulator lever (for a shallower tilling depth).

• This tiller can be operated in CRT (counter-rotating tine) mode. 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 when operating in CRT mode, 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 (or simply switch to operating in FRT mode).

• Avoid the temptation to push down on the handlebar 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. (Sometimes, slight downward pressure on the handlebar will help get
through a particularly tough section of sod or unbroken ground, but in most cases this won’t
be necessary.)

With experience, you will find the “just right” tilling depth and tine rotation combination
that is best for your garden under specific conditions.

Let the Tiller Do the Work Avoid Making Footprints

While tilling, relax and let the wheels pull the
tiller along while the tines do the digging.
Walk on the side that is not yet finished (to
avoid making footprints in the freshly tilled
soil) and lightly, but securely grip the han­dlebar with just one hand.

Always operate
the tiller with the throttle in the FAST (rab­bit) position.

Whenever possible, walk on the untilled
side of the unit to avoid making footprints in
your freshly tilled or cultivated soil. Foot­prints cause soil compaction that can ham­per root penetration and contribute to soil
erosion. They can also “plant” unwanted
weed seeds back into the freshly tilled
ground.

Preparing Seedbeds

• 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 Seedbed 1). When fin­ished in one direction, make a second pass at a right angle (Seedbed 2). Overlap
each pass for best results (in very hard ground, it may take three or four passes to
thoroughly pulverize the soil.)

• If the garden size will not permit lengthwise and then crosswise tilling, then over­lap the first passes by one-half a tiller
width, followed by successive passes
at one-quarter width (see Seedbed

3).

Seedbed 3

Avoid Tilling Soggy, Wet Soil

Tilling wet soil often results in large, hard
clumps of soil that can interfere with plant­ing. If time permits, wait a day or two after
heavy rains to allow the soil to dry before
tilling. Test soil by squeezing it into a ball. If
it compresses too easily, it is too wet to till.

Seedbed 1 Seedbed 2

Cultivating

With planning, you can
allow enough room
between rows to cultivate.
Leave room for the hood
width, plus enough extra
room for future plant
growth.

Tilling On Slopes

TILLING TIPS & TECHNIQUES (CON’T)

Read the following recommendations before tilling on slopes:

If you must garden on a moderate slope, please follow two very important guidelines:

1. Till only on moderate slopes, never on steep ground where footing is difficult (review safe­ty rules in Section 1: Safety of this manual).

2. We recommend tilling up and down slopes rather than terracing. Tilling vertically on a
slope allows maximum planting area and also leaves room for cultivating.

IMPORTANT: 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 gravitate

WARNING: Do not

operate tiller on a slope too
steep for safe operation. Till
slowly and be sure you have
good footing. Never permit
tiller to freewheel down
slopes. Failure to follow this
warning could result in
personal injury.

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!

Tilling Up and Down Slopes (Vertical Tilling)

• 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.

• 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.

Clearing the Tines

The tines have a self-clearing action which eliminates most tangling of debris in the
tines. However, occasionally dry grass, stringy stalks or tough vines may become tan­gled. Follow these procedures to help avoid tangling and to clean the tines, if neces­sary.

• 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.

• While tilling, try swaying the handlebars from side to side (about 6" to 12"). This
“fishtailing” action often clears the tines of debris.

• If tangling occurs, lift the tines out of the soil and run the tiller in reverse for a few
feet. This reversing action should unwind a good deal of debris.

• It may be necessary to remove the debris by hand (a
pocket knife will help you to cut away the material).

WARNING: Before clearing the

tines by hand, stop the engine, allow all
moving parts to stop. Failure to follow
this warning could result in personal
injury.

Loading and Unloading the Tiller

WARNING: Loading and

unloading the tiller into a vehicle is
potentially hazardous. Doing so is
NOT recommend 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, stop the engine,
wait for all parts to stop moving and allow the
engine and muffler cool.

• The tiller is too heavy and bulky to lift safely
by one person. Two or more people should
share the load.

• Use sturdy ramps and manually (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 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 its parking brake.

• When going up ramps, stand in the normal
operating position and push the tiller ahead of
you. Have a person at each side to turn the
wheels.

14

• When going down 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 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 placing the wheel shift lever in the FOR­WARD position. Chock the wheels with blocks
and securely tie the tiller down.

SECTION 5: MAINTENANCE AND ADJUSTMENTS

WARNING: Before performing any

maintenance, or repairs, turn the engine off and
allow it to cool, move the tiller to a level surface,
place the wheel shift lever in the FORWARD
position and chock the tiller’s wheels.

Spark Plugs

The spark plug should be cleaned and the gap reset once
a season. Refer to the Briggs & Stratton Operator/Owner
Manual for correct plug type and gap specifications.

Cleaning the Tiller

Any fuel or oil spilled on the machine sh ould be wiped off
promptly. Do NOT allow mud and debris to accumulate
around the cooling fins of the engine or on any other pa rt
of the machine, especially around the bottom frame
cover, under the belt cover, around the belts, pulleys,
shifter linkage and other moving parts.

• Remove the belt cover at least once a season and
clean any debris away from belts and pulleys

• Clean around the bottom frame cover and the
underside of the tine shield and with a garden hose
after each use.

IMPORTANT:

the handle panel) at least once a season with light oil.
Remove the belt cover at least once a season and clean
any debris away from belts and pulleys before lubricating
pivot points on pulley brackets with a light oil.

Axles (Wheel & Tine)

Remove each wheel and tine holder from its axle at least
once a season and before extended storage. Clean each
axle and lubricate with an all-purpose grease before
reinstalling each wheel and tine holder.

Transmission

Checking for Oil Leaks

Before each use, check your tiller for signs of an oil leak—
usually a dirty, oily accumulation either on the unit or on
the floor where it has been parked.

A little seepage around a cover or oil seal is usually not a
cause for alarm. If a small puddle forms below the tiller
within hours, however, then service is required.

15

Ignoring a leak can result in severe transmission damage.
If a cover leaks, try tightening any loose screws or bolts. If

the fasteners are tight, a new gasket or oil seal may be
required. If the leak is from around a shaft and oil seal, t he
oil seal probably needs to be replaced. See a n authorized
service dealer.

Changing Oil

Oil level should be visually checked if evidence of a leak
is present. Oil should be added in such cases, but
changing the transmission oil as part of general
maintenance is unnecessary

Checking Oil Level

Check the oil level after every 30 hours of operation and
whenever there is any oil leakage.

IMPORTANT:

low on oil.

1. Position the tiller on a level surface.

2. Remove the fill plug found on the front of the
transmission. See Figure 2.

Never operate the tiller if the transmission is

Checking Hardware

Check the unit for loose or missing hardware after every
10 operating hours. Loose or missing hardware can lead
to equipment failure, poor performance, or oil lea ks.

Be sure to check the three mounting screws located on
each of two end caps found at the rear of the transmission
(See Figure 3). Lift the tine flap to service those screws.

Handle Height

The handle mount bracket can be adjusted downward (for
shorter operators) or upward (for taller ope rators) using
the handle height adjuster .

• Unthread the handle crank and remove the carriag e
bolt which secures handle mount bracket to the tiller
frame. See Figure 4.

• Pivot the handlebar upward or downward to align the
handle mount bracket’s rear holes (either upper or
lower) with the holes in the tiller frame.

• Re-insert the carriage bolt through the holes from
right to left and secure it with the hand le crank.

Tines

The tines will wear with use and should be inspected at
the beginning of each tilling season and after every 30
operating hours.

WARNING: Position the tiller on flat, level

surface, chock the wheels, shut the engine off
and allow it to cool before inspecting or
removing the tines.

NOTE: The tine shield end-covers (left side and right

side) must be removed in order to take off eithe r a single
tine holder or individual tines. The end-covers are
secured to the tine shield housing with three hex nuts
each.

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 ch opping up and
turning under organic matter.
