1. Beforeengagingthe ForwardClutch

Control, put the WheelGearLeverin the

ENGAGEposition (see"WARNING"

below).

2. Pull up andhold oneor both of the

levers againstthe handlebar grips to

engagethe wheels and tines.

3. ReleaseBOTHleversto disengage

(stop) the wheelsandtines. All forward

motion will stop (the enginewill continue

to run).

Never place the Wheel Gear Lever in

DISENGAGE (Freewheel) when the

engine isrunning.

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.

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 isusedfor maneuveringthe

tiller only- neverengagethe tines in

the groundwhile goingin the reverse

direction.

• Use extreme caution when reversing

or pulling the machine towards you.

Lookbehindtoavoidobstacles.

• Neverattempttotill 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).

• 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.

DEPTH REGULATOR

The Depth Regulator lever(D, Figure3-2)

controls the tilling depth of the tines. Pull

the leverstraight backand slide it up or

downto engagethe notchedheight set-

tings.

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 theground.

Moving the lever up increasesthe tilling

depth. Thelowest notch allowsa tilling

depth of approximately six to eight

inches,depending on soil conditions.

Forbestresults,always begintilling at

a very shallowdepthsettingand gradu-

ally increasethetilling depth. Complete

details onusing the DepthRegulatorare

found inthe "Operation" Sectionof this

manual.

HANDLEBAR HEIGHT ADJUSTMENT

The handlebarheight is adjustableto four

different settings. Setthe handlebar

heightto a comfortable setting, but keep

in mindthat the handlebarswill belower

when thetines areengagedinthe soil.

ToAdjusttheHandlebarHeight:

OPERATINGTHETILLER

Thefollowing pagesprovideguidelines to

usingyour tiller effectively and safely in

various gardening applications. Besure

to read"Tilling Tips &Techniques" inthis

Section beforeyou 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 tinetillers.

1. Followthe "Pre-Start Checklist" onthe

previous page. Besure thatthe Wheel

GearLeveris inthe ENGAGEposition.

2. Putthe Depth RegulatorLeverin the

"travel" position (leverall the waydown)

so that the tines areclear of the ground.

Usethis position when practicingwith

your tiller or when moving to or from the

garden. Whenyou arereadyto begin

tilling, you must movethe Depth Regula-

tor Leverto the desireddepth setting (see

"Tilling Tips & Techniques").

3. Start theengine andallow itto warm

up. Whenwarm, put EngineThrottle

Control Leverin "FAST"speedsetting.

Keepawayfrom rotatingtines. Rotating

tines will causeinjury.

4. For forward motion of the wheels and

tines:

(a) Pull one or both of the Forward

Clutch Control Levers up andhold

them against the handlebars. To

stop forward motion of the wheels

and tines, releasethe levers.

Figure4-2: Useone handto guide 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 securegrip with one hand

on the handlebars,but keepyour

arm loose. SeeFigure4-2. Letthe

tiller move aheadat its own pace

and do not push down onthe han-

dlebarsto try andforce the tiller to

dig deeper- this takesweight off the

wheels, reducestraction, and causes

the tines to try and propel thetiller.

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 behindandexercisecaution

when operating in reverse. Do not

till while in reverse.

(b) Stop allforward motion before

reversing. Lift the handlebarswith

one hand until the tines are off the

ground andthen pull the Reverse

Clutch Control knob out to engage

reverse motion (seeFigure4-3). To

stop reversemotion, let go ofthe

ReverseClutch Control knob.

Figure4-3: Raise tinesoffgroundand look

behindwhen movingin reverse.

6. To Turn theTiller Around:

(a) Practiceturning the tiller in a level,

open area. Bevery carefulto keep

your feet and legsawayfrom the

tines.

(b) To makea turn, reducethe engine

speedandthen lift the handlebars

until the engine and tines arebal-

ancedoverthe wheels (Figure4-4).

tiller in the direction ofthe turn

(Figure4-5). After completing the

turn, slowly lower thetines into the

soil andincreasethe enginespeed.

StoppingtheTiller and Engine

1. To stopthe wheels andtines, release

the Forward ClutchControl levers or the

ReverseClutchControl knob whichever

isengaged).

2. To stopthe recoil start engine, move

the EngineThrottle Control Leverto

"STOP". Onelectric start models,turn the

ignition keyswitchto "OFF"to stop the

engine.

Beforetilling, contactyourtelephoneor

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.

TillingTips& Techniques

Letthetiller dothe work

• While tilling, relaxandlet 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 grip the handlebar

with just one hand.

• Avoid pushing down on the handlebars

in an attempt to force the tiller to dig

deeper. Doingso 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 mostcasesthis won't be necessary

at all.)

Tilling depths

• Avoid trying to digtoo 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 newly worked soil set for a

day or two beforemaking afinal, deep

tilling pass.)

• Whencultivating (breakingup the

surfacesoil around plantsto help

destroyweeds),usevery shallowdepth

settingsto preventinjuryto plantswhose

rootsoftengrow closetothesurface. If

needed,lift up onthe handlebarsslightly

to preventthetinesfrom diggingtoo

deeply. (Cultivatingona regularbasis

notonlyeliminatesweeds,it alsoloosens

andaeratesthesoil for bettermoisture

absorptionandfasterplantgrowth.)

Avoidtilling soggy,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 allowthe soil

to dry beforetilling. Testsoil by squeez-

ing it into a ball. If it compressestoo

easily, it is too wet to till.

Avoid making footprints

When possible,walk onthe untilledside

of the unit to avoid makingfootprints in

thefreshly tilled soil. Footprintscause

soil compaction that canhamperroot

penetrationandcontribute to soil

erosion. They canalso"plant" unwanted

weedseedsback intothe freshly tilled

ground.

Choosing correct wheel

and tine speeds

With experience,you will find the "just

right" tilling depth andtilling speedcom-

binationthat is bestfor your garden.

Setthe EngineThrottle ControlLeverto

a speedto give the engineadequate

powerand yet allow it to operateatthe

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 thetilling

depth, will ensurea sufficient power

levelto do the job without causingthe

engine to labor.

Suggestedtilling patterns

• When preparinga seedbed,go overthe

same pathtwice in thefirst row, then

overlapone-half thetiller width on the

rest ofthe passes(see Figure4-6).

Whenfinished in one direction, makea

second pass ata right angle asshown

in Figure4-7. Overlapeachpassfor

best results (invery hard ground it may

takethree or four passesto thoroughly

pulverizethe soil).

• Ifthe garden sizewill not permit

lengthwiseand then crosswisetilling,

then overlapthe first passesby one-

halfa tiller width, followed bysucces-

sive passesat one-quarterwidth (see

Figure4-8).

• With planning,you canallow enough

room between rows to cultivate (see

Figure4-9). Leaveroom for the hood

width, plusenoughextraroom for

future plantgrowth.

TillingTips& Techniques

Clearingthetines

Thetines havea self-clearingaction

which eliminates most tangling of debris

in the tines. However,occasionally dry

grass, stringy stalksor tough vines may

becometangled. Followthese proce-

duresto help avoidtangling and to clean

the tines, if necessary.

• To reducetangling, set the depth regu-

lator deepenoughto get maximum

"chopping" action asthe tines chop the

materialagainstthe ground. Also, try

to till under crop residuesor cover

crops while theyare green, moist and

tender.

• While power composting, try swaying

the handlebarsfrom sideto side (about

6"to 12"). This"fishtailing" action

often clearsthe tines of debris.

• Iftangling occurs, lift the tines out of

the soil and runthe tiller in reversefor

a few feet. This reversingaction

should unwind agood deal of debris.

• If reversingthe tiller doesn't clearthe

debris, it may benecessaryto remove

the debris by hand (a pocketknife will

helpyou to cut awaythe material).

Beforeclearingthetines byhand, stop

the engine, allow all moving parts to

stop and disconnect the spark plug

wire. Removethe ignition keyon elec-

tric start models.

Failure to follow this warning could

resultin personalinjury.

Tillingonslopes

If you must garden on a moderate

slope, pleasefollow two very important

guidelines:

1.Till only on moderate slopes, neveron

steep ground where footing isdifficult

(reviewsafety rules in the "Safety"

Section of this Manual).

2. We recommendtilling upand down

slopes ratherthanterracing. Tilling

vertically ona slope allows maximum

plantingarea andalso leavesroom for

cultivating.

IMPORTANT:Whentilling on slopes, be

sure thecorrect oil levelis maintained in

the engine (checkevery one-half hourof

operation). The inclineof the slope will

causethe oil to slant awayfrom its

normal levelandthis canstarveengine

parts of required lubrication. Keepthe

engine oil levelatthe full point atall

times!

A. Tilling up anddownslopes:

• To keepsoil erosionto a minimum, be

sureto add enough organic matterto

the soil so that it hasgood moisture-

holding texture andtry to avoid leaving

footprints or wheelmarks.

• Whentilling vertically, try to makethe

first pass uphill asthe tiller digs more

deeplygoing uphillthan it does down-

hill. Insoft soil or weeds,you may

haveto lift the handlebarsslightly while

going uphill. Whengoing downhill,

overlapthe first pass by about one-half

the width of the tiller.

B. TerraceGardening:

• Whena slope is too steepor too short

for vertical tilling, it may be necessary

to till across theslope and createter-

racedrows. Terracesare rowsthat are

cut into the side of aslope,creating a

narrow, but flat areaon which to plant.

• Ona long slope, you can makeseveral

terraces, one below the other.

Terracesshould be only 2-to-3 feet

wide. Digging too far intothe side of

the slope will expose poor subsoil that

is unproductivefor plants.

To createaterrace,start atthe top of

the slope and work down. Goback and

forth acrossthe first row asshown in

Figure4-10.

Eachsucceedinglower terrace is

started bywalking belowthe terrace

you're preparing. Foraddedstability of

the tiller, always keepthe uphill wheel

in the soft, newly tilled soil. Donot till

the last 12"or more ofthe downhill

outside edgeof eachterrace. This

untilled strip helps preventstheter-

racesfrom breakingapartand washing

downhill. It also providesa walking

path betweenrows.

, ll::e

o3mmr,

O_l_' REPEAT

Figure4-10

C. Tilling acrossslopeswithout

usingterraces:

• Ifvertical or terracinggardening aren't

practicalfor you, then you cantill later-

ally across a slope. We don't really

recommendthis methodas it can

create unsurefooting and invites soil

erosion.

As in terracegardening,start at thetop

ofthe slopeand overlapthefirst pass

by halfthe width of the tiller. Foradded

stability of thetiller, always keepthe

uphill wheel inthe soft, newlytilled soil.

POWERCOMPOSTING

Powercomposting simply meanstilling

under and burying in the soil all manner

of organic mattersuch ascrop residues,

leaves,grass clippings and cover crops.

This materialwill decomposeduring the

non-growing season andadd important

naturalnutrients to the soil.

When power composting, do not keep

the Depth Regulator Lever at a deep

settingifthetiller jumpsor bucks.

If jumping or buckingoccurs, movethe

Depth Regulator Lever downto one of

the shallower settings and then slowly

increase the tilling depth on later

passes.

Failure to follow this warning could

resultin personalinjury.

Thefirst placeto beginis with crop

residuessuch as leftovervines, stalks,

stems and roots. Powercompost these

crop residues assoon asthey finish

bearing. Thesooner this isdone,the

better,astender green matter is easierto

till under. Usethe deepestdepth regula-

tor setting possiblewithout causing the

engine to labor or the tiller to jump ahead.

Standingcornstalks of reasonableheight

can be power composted. Pushing over

(but not uprooting) cornstalks will often

makeit easierfor your tiller to chop up

the stalks. Keepthe tines clear of exces-

sive tangling by "fishtailing" or frequently

using reverse. Makeseveral passes,then

return afew days laterto finish off any

remainingstubble.

After tilling under crop residues,add

more organic matter such as leaves,

grass clippings and evenkitchenscraps.

Whentilled intothe soil, this organic

matter will decomposeandaddeven

more important nutrients to the soil.

After power composting, you may want to

less incline to the ramp, the better).

LOADINGANDUNLOADING Turnthe vehicle'sengineoff andapply

THETILLER its parking brake.

Loading and unloading the tiller into a

vehicle is potentially hazardousand we

don't recommenddoingso unlessabso-

lutely necessary,as this could result in

personalinjuryor propertydamage.

However, if you mustloador unloadthe

tiller, followthe guidelinesgivennext.

• Beforeloading or unloading,stop the

engine,wait for all partsto stop moving,

disconnectthe spark plug wire and let

the engine and muffler cool. Remove

the ignition keyon electric start models.

• Thetiller is too heavy(over 170 Ibs.,

dependingon model) and bulky to lift

safely by one person.Two or more

peopleshould sharethe load.

• Usesturdy ramps and manually(engine

shut off) roll thetiller into andout of the

vehicle. Two or more people areneeded

• Rampsmust bestrong enoughto

support the combined weight ofthe tiller

and any handlers.The ramps should

provide good traction to prevent slip-

ping; they should haveside rails to

guidethe tiller along the ramps;and

they should havea locking deviceto

securethem to the vehicle.

• Whengoing up ramps,stand in the

normal operating position andpush the

tiller aheadof you. Havea personat

eachsideto turn the wheels.

• Whengoing down ramps, walk back-

ward with thetiller following you. Keep

alertfor any obstaclesbehindyou.

Position a personat eachwheel to

control the speedof thetiller. Nevergo

down ramps tiller-first, as thetiller could

tip forward.

• Usewooden blocksto placeon the

downhill side of the wheels if you need

to stopthe tiller from rolling down the

ramp. Also, usethe blocksto temporar-

ily keepthetiller in placeon the ramps

(if necessary),and to chock the wheels

in placeafter thetiller is in the vehicle.

• Whenthetiller is in the vehicle, prevent

it from rolling byengagingthe wheels in

the wheel drive position (put Wheel Gear

Leverin ENGAGE).Chockthe wheels

with blocks andsecurelytie thetiller

to dothis. down.

CHECKHARDWARE

At least every 10 operating hours,check

the unit for loose or missing hardware

(screws, bolts, nuts, hairpin cotters, etc.).

Looseor missing hardwarecan leadto

equipment failure, poor performanceor

oil leaks.

Besureto checkthethree end cap

mounting screws locatedat the rear of the

transmission (Figure5-2). Lift the tine

flap to servicethose screws.

CHECKTIRE PRESSURE

Checkthe air pressurein bothtires.

Deflateor inflate bothtires evenlyto 15-

to-20 PSI (pounds persquareinch). Be

sure that bothtires havethe sameair

pressureor the unit will tendto pull to

one side.

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to

come to a complete stop, disconnect spark plug wire and move wire away from spark plug.

Remove the keyfrom the keyswitch on unitsso equipped.

Failure to follow these instructionscan result in serious personal injury or property damage.

CHECKFOROILLEAKS

Beforeeachuse, checkyour tiller for

signs of anoil leak- usually a dirty, oily

accumulation either on the unit or onthe

floor where it has beenparked.

A littleseepagearound a cover or oil seal

is usually not a causefor alarm. However,

ifthe oil drips overnight then immediate

attention is neededas ignoring a leakcan

result in severetransmission damage.

If a cover is leaking,try tightening any

loosescrews or bolts. Ifthe fasteners are

tight, anewgasket or oil seal may be

required. If the leak isfrom around a

shaft and oil seal,the oil seal probably

needsto be replaced. Seeyour autho-

rizeddealeror contactthe factoryfor

service or advice.

IMPORTANT:Neveroperatethe tiller if

the transmission is low on oil. Checkthe

oil levelafter every30 hours of operation

and wheneverthere is anyoil leakage.
