3 Featuresand Controls

Before operating your machine, care-
fully read and understand all safety,

controls and operating instructions in
this Manual, the separate Engine
Owner's Manual, and on the decals on

the machine.

Failure to follow these instructionscan

resultin seriouspersonalinjury.

Figure3-1: Controlslocatedon handlebar.

INTRODUCTION

This Sectiondescribesthe location and
function of the controls on your tiller.

Referto thefollowing section "Operation"

for detailedoperating instructions.

Practiceusingthese controls, with the
engine shut off, until you understandthe
operation of the controls and feel confi-

dent with them.

IMPORTANT:Referto the separateengine

manufacturer'sEngineOwner's Manual
for information about the controls on the

engine.

WHEEL GEAR LEVER

This lever(A, Figure3-1) has two posi-
tions: ENGAGEand DISENGAGE.

Inthe ENGAGEposition, the wheels will
start turning when eitherthe Forward

Clutch Control or the ReverseClutch
Control is engaged(the tines will also

start turning when eitherclutch is
engaged).

The DISENGAGEposition placesthe
wheels inthefreewheeling modeto allow
the unitto be moved without the engine

running. Usethe DISENGAGEposition
only whenthe engine is not running. See

"DANGER"statementthat follows.

To shift to ENGAGE,gently (do not force)

movethe leverforward while also rolling

the tiller afew inchesforward or back-
ward. Moving the tiller helpsto align the

shift mechanismwith the transmission
wheel drive gears.

To shift to DISENGAGE(freewheel),

movethe lever rearward, without rolling
the tiller. Thewheels will roll freely
when the lever is properly set in the

DISENGAGEposition.

Never place the Wheel Gear Lever in

DISENGAGE (Freewheel) when the
engine is running.

Having the Wheel Gear Lever in

DISENGAGE and then engaging the
tines/wheels with either the Forward
Clutch Control or the Reverse Clutch

Control could allow the tines to propel
thetiller rapidlyforwardor backward.

Failure to follow this instruction could
result in personal injury or property

damage.

The two interconnected levers (B, Figure

3-1) control the engagementof forward
drive to the wheelsand tines.

To Operatethe ForwardClutchControl:

1. Beforeengagingthe ForwardClutch

Control, put the WheelGearLeverin the
ENGAGEposition (see"WARNING"
below).

2. Pull up and hold one or both of the
levers againstthe handlebar grips to
engagethe wheels and tines.

3. ReleaseBOTHleversto disengage
(stop) the wheels andtines. All forward
motion will stop (the enginewill continue

to run).

Never engagethe wheels andtines with

the Forward Clutch Control or the

Reverse Clutch Control unless the
Wheel GearLeveris in ENGAGE.

Engagingthe ForwardClutch Controlor

the Reverse Clutch Control when the
wheels are not engagedcouldallow the

tines to rapidlypropelthe tiller forward

or backward.
Failure to follow this warning could

result in personal injury or property
damage.

REVERSE CLUTCH CONTROL

The ReverseClutchControl (C, Figure

3-1) controls the engagementof reverse
driveto thewheels and tines. The revers-

ingfeature is usedfor maneuveringthe

tiller only- neverengagethe tines in
the groundwhile goingin the reverse

direction.

• Use extreme caution when reversing
or pulling the machine towards you.

Lookbehindto avoid obstacles.

• Neverattemptto till in reverse.

Failure to follow this warning could
result in personal injury or property
damage.

To Operatethe ReverseClutchControl:

1. Putthe WheelGearLeverin the

ENGAGEposition (seethe "WARNING"
statementon previouspage).

2. Stopall tiller motion by releasingthe

ForwardClutch Control levers.

3. Lift upthe handlebarsuntil thetines

clearthe ground, look behindyou to avoid
anyobstacles,and then pull the Reverse

ClutchControl knob out. Thetines and
wheelswill rotate in a reverse direction.

4. Releasethe ReverseClutch Control

knobto disengage(stop) the wheels and

tines. All reversemotion will stop (the

enginewill continue to run).

Figure3-2: DepthRegulatorLever.

The highest notch (leverall the way
down) raisesthe tines approximately

1-1/2 inches off the ground. This "travel"
position allowsthetiller to be moved

without the tines digging into the ground.

Moving the lever up increasesthe tilling
depth. Thelowest notch allows a tilling
depth of approximately six to eight

inches,depending on soil conditions.

Forbest results,always begintilling at
a very shallowdepthsettingand gradu-
ally increasethe tilling depth. Complete

details onusing the Depth Regulatorare
found in the "Operation" Section of this

manual.

HANDLEBAR HEIGHT ADJUSTMENT
The handlebarheight is adjustableto four

different settings. Setthe handlebar

heightto a comfortable setting, but keep

in mindthat the handlebarswill be lower
when thetines are engagedin the soil.

ToAdjustthe HandlebarHeight:

keyedwasher into the slot. Tighten the
height adjustment screw securely.

5. Retightenthe two screws at the ends
of the handlebar.

ENGINECONTROLS

Referto the engine manufacturer'sEngine
Owner's Manual(included in thetiller lit-
erature package)to identify the controls
on your engine. The following two con-
trols areusedwhen stopping or starting
the engine.

IMPORTANT:The control for stopping
the recoil start engineis locatedon the
engine.

ENGINE THROTTLE CONTROLLEVER
TheEngineThrottleControlLever(located

on engine--see Figure 4-1) is usedto reg-
ulatethe engine speed. Onthe recoil start
model only, it is also usedto stop the
engine (on the electric start model,the
electric start keyswitch is usedto stop the
engine). The throttle settings are shown

below.
IMPORTANT:See"Starting and Stopping

the Engine" in the "Operation" Sectionfor
detailedenginestarting andstopping

instructions.

FAST- Usefor most tilling and

cultivating projects.

-l_ SLOW- Usewhen idling engineor
when slower tilling and cultivating

speeds are needed.

• Do not attempt to till too deeply too
quickly. Gradually work down to
deepertilling depths.

• Placethe DepthRegulatorLever inthe
"travel" position before starting the
engine. This position prevents the
tines from touching the ground until
youare readytobegintilling.

Failure to follow this warning could
result in personal injury or property
damage.

To Start the ElectricStart EngineWith
the Recoil StarterRope

If necessary,the electric start engine can
be started with the recoilstarter rope by

following the steps below:

1. If the battery is not "dead" or
damaged,leaveit connectedto the tiller
so it will be rechargedduring engine
operation. Makesure the battery cells are

filled to the UPPERLEVELline with elec-
trolyte.

2. If the battery is "dead" or damaged,
remove it (referto "Battery Removal and

Installation" in Section 5) and have it

tested. Beforestarting engine, coverthe
terminal on the looseend of the positive

(+) cable with the insulatedboot and
secure it in placewith electricaltape to

prevent electrical sparks.

control is engaged).

2. Tostop the engine on the recoil start
model, move the EngineThrottle Control
Leverto the "STOP" position.

3. Tostop theengine on an electricstart
model, move the ignition keyto "OFF".

IMPORTANT:Afterstopping anelectric
start engine, removethe ignition keyfrom

the switch to reduce the possibility of

unauthorizedstarting of the engine.

OPERATINGTHETILLER

Thefollowing pagesprovideguidelines to

usingyour tiller effectively and safely in
various gardening applications. Besure
to read"Tilling Tips &Techniques" in this
Section before you actually put the tines

intothe soil.
This isa traditional "standard rotating

tine" tiller with forward rotating tines. It
operatescompletely differently from CRT

(CounterRotating Tines)tillers or from

low-cost front tine tillers.

1. Followthe "Pre-Start Checklist" on the

previous page. Besure thatthe Wheel
GearLeveris in the ENGAGEposition.

2. Putthe Depth Regulator Leverin the
"travel" position (lever all the way down)
so that the tines areclear of the ground.

Usethis position when practicingwith
your tiller or when movingto orfrom the
garden. When you are readyto begin
tilling, you must movethe Depth Regula-
tor Leverto the desireddepth setting (see
"Tilling Tips & Techniques").

3. Start theengine and allow it to warm

up. When warm, put EngineThrottle
Control Leverin "FAST"speedsetting.

Keepawayfrom rotatingtines. Rotating

tines will causeinjury.

4. For forward motion of the wheelsand
tines:

(a) Pull one or both of the Forward

Clutch Control Levers up and hold
them against the handlebars.To
stop forward motion of the wheels

and tines, releasethe levers.

Figure4-2: Useone handtoguide tiller

whenmovingforward.

(b) Asthe tiller movesforward, relax

and let the wheels pull the unit along
while the tines dig. Walk behind and

a little to oneside of the tiller. Usea
light but secure grip with one hand

on the handlebars,but keepyour
arm loose. SeeFigure4-2. Letthe
tiller move aheadat its own pace
and do not push down on the han-
dlebarsto try andforce the tiller to
dig deeper- this takesweight off the
wheels, reducestraction, and causes
the tines to try and propel the tiller.

Do not push down on the
handlebars to try to make the tiller till
more deeply. This preventsthe wheels
from holding the tiller back and can
allow the tines to rapidly propel the
tiller forward,whichcould resultin loss
of control,propertydamage, or personal

injury.

5. Forreverse motion of the wheelsand
tines:

(a) Look behind andexercisecaution

when operating in reverse. Do not

till while in reverse.

(b) Stop all forward motion before

reversing. Lift the handlebarswith
one hand until the tines areoff the

ground andthen pull the Reverse
Clutch Control knob out to engage
reverse motion (seeFigure 4-3). To
stop reversemotion, let go ofthe

ReverseClutch Control knob.

Figure4-3: Raise tinesoffgroundand look
behindwhen movingin reverse.

6. To Turn the Tiller Around:
(a) Practiceturning the tiller in a level,

open area. Bevery careful to keep
your feet and legsawayfrom the

tines.

(b) To makea turn, reducethe engine

speedandthen lift the handlebars
until the engine and tines are bal-
ancedoverthe wheels (Figure4-4).

(c) With the tiller balanced,pushside-

ways on the handlebarto move the
tiller in the direction ofthe turn

(Figure4-5). After completing the
turn, slowly lower the tines into the
soil and increasethe enginespeed.

StoppingtheTiller and Engine

1. To stop the wheelsandtines, release

the Forward ClutchControl levers or the

ReverseClutch Control knob whichever
isengaged).

2. To stop the recoil start engine, move
the EngineThrottle Control Leverto
"STOP". Onelectric start models,turn the

ignition keyswitchto "OFF"to stop the

engine.

Beforetilling, contactyour telephoneor
utilities company and inquire if
underground equipment or lines are
used in your area. Their representative
will be glad to answer your questions
and tell you if any oftheir equipmentor

lines are buried underground on your

property.

Turningthe Tiller Around

TillingTips& Techniques

Letthetiller dothe work

• While tilling, relaxand let the wheels
pull the tiller along while thetines do

the digging. Walk on the sidethat is

notyet finished (to avoid making foot-
prints inthe freshly tilled soil) and

lightly, butsecurely gripthe handlebar

with just one hand.

• Avoid pushing down on the handlebars
in an attempt to force the tiller to dig

deeper. Doing so takesthe weight off
the poweredwheels,causing them to

losetraction. Without the wheels
helpingto hold the tiller back,the tines

will attempt to propel the tiller - often
causing the tiller to skip rapidly across

the ground. (Sometimes, slight down-
ward pressureon the handlebarswill

helpget through a particularly tough

section of sod or unbrokenground, but

in mostcases this won't be necessary

at all.)

Tilling depths

• Avoid trying to dig too deeplytoo

quickly, especiallywhen busting sod or
when tilling soil that hasn't beentilled
for some time. Useshallow depth reg-

ulator settings (only an inch or two

deep) for the first passesthrough the
garden area. With eachsucceeding

pass,adjust the depth regulatorto dig

another inch or two deeper. (Watering
the garden areaa few days prior to
tilling will maketilling easier,as will

letting the newlyworked soil set for a

day or two beforemaking a final, deep
tilling pass.)

• When cultivating (breaking up the

surfacesoil around plantsto help
destroyweeds),usevery shallow depth
settingsto preventinjury to plantswhose

rootsoftengrow closetothesurface. If
needed,lift uponthe handlebarsslightly

to preventthetinesfrom diggingtoo
deeply. (Cultivatingona regularbasis

notonlyeliminatesweeds,it also loosens

andaeratesthesoil for bettermoisture
absorptionandfaster plantgrowth.)

Avoidtillingsoggy,wetsoil

Tilling wet soil often results in large,

hardclumps of soil that can interfere
with planting. Iftime permits, wait a day
or two after heavyrainsto allow the soil
to dry before tilling. Test soil by squeez-

ing it into a ball. If it compresses too
easily, it is too wet to till.

Avoid making footprints

When possible,walk on the untilledside
of the unit to avoid makingfootprints in
thefreshly tilled soil. Footprintscause
soil compaction that canhamperroot

penetrationandcontribute to soil
erosion. They can also"plant" unwanted
weedseedsback intothe freshly tilled
ground.

Choosing correctwheel

and tine speeds

With experience,you will find the "just

right" tilling depth andtilling speed com-

binationthat is best for your garden.
Setthe EngineThrottle Control Lever to

a speed to give the engineadequate

powerand yet allow it to operate at the
slowest possiblespeed...atleast until
you haveachievedthe maximum tilling
depth you desire. Fasterengine speeds

may bedesirablewhen making final

passesthrough the seedbedor when
cultivating. Selectionof the correct
engine speed, in relationto the tilling
depth, will ensurea sufficient power

levelto do the job without causingthe
engine to labor.

Suggestedtilling patterns

• When preparinga seedbed,go overthe

same path twice in thefirst row, then
overlapone-half thetiller width on the
rest ofthe passes(see Figure4-6).
Whenfinished in onedirection, make a
second pass ata right angle asshown
in Figure4-7. Overlapeach passfor
best results (in very hardground it may
takethree or four passesto thoroughly
pulverizethe soil).

• Ifthe gardensizewill not permit
lengthwiseand then crosswisetilling,

then overlapthe first passesby one-

halfa tiller width, followed by succes-

sive passesat one-quarter width (see

Figure4-8).

• With planning,you canallow enough
room between rows to cultivate (see
Figure4-9). Leaveroom for the hood

width, plus enough extra room for
future plantgrowth.
