drive to the wheelsandtines.
To Operatethe ForwardClutchControl:
1. Beforeengaging the Forward Clutch
Control, put the WheelGearLeverin the
ENGAGEposition (see"WARNING"
below).
2. Pull up and hold one or both of the
levers against the handlebargrips to
engagethewheels and tines.
3. ReleaseBOTHleversto disengage
(stop) the wheels andtines. All forward
motion will stop (the enginewill continue
to run).
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
the tiller rapidlyforwardor backward.
Failure to follow this instruction could
result in personal injury or property
damage.
Never engagethe wheels and tines 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 rapidly propelthe tiller forward
or backward.
Failure to follow this warning could
result in personal injury or property
damage.
REVERSECLUTCHCONTROL
TheReverseClutch Control (C, Figure
3-1) controls the engagementof reverse
drive to thewheels and tines. The revers-
ingfeature isusedfor maneuveringthe
tiller only- neverengagethetines in
thegroundwhile goingin the reverse
direction.
Use extreme caution when reversing
or pulling the machine towards you.
Lookbehindto avoidobstacles.
Neverattempttotill in reverse.
Failure to follow this warning could
result in personal injury or property
damage.
ToOperatetheReverseClutchControl:
1. Putthe WheelGearLeverin the
ENGAGEposition (seethe "WARNING"
statementon previous page).
2. Stopall tiller motion by releasingthe
Forward ClutchControl levers.
3. Lift up the handlebarsuntil the tines
clearthe ground, look behindyou to avoid
anyobstacles,and then pull the Reverse
ClutchControl knob out. Thetines and
wheelswill rotate in a reversedirection.
4. Releasethe ReverseClutch Control
knob to 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 in the
"travel" position before starting the
engine. This position prevents the
tines from touching the ground until
youare readyto begintilling.
Failure to follow this warning could
result in personal injury or property
damage.
DEPTHREGULATOR
TheDepth Regulator lever(D, Figure3-2)
controls the tilling depth ofthetines. Pull
the leverstraight backand slide it up or
down to engagethe notchedheight set-
tings.
Figure3-2: DepthRegulatorLever,
The highest notch (leverall the way
down) raises thetines approximately
1-1/2 inches off the ground. This "travel"
position allows the tiller to be moved
without the tines digging into the ground.
Moving the lever up increasesthe tilling
depth. Thelowest notch allows a tilling
depthof approximately six to eight
inches,depending on soil conditions.
Forbestresults, alwaysbegintilling at
a veryshallowdepthsettingand gradu-
ally increasethetilling depth. Complete
details on using the Depth Regulatorare
found in the "Operation" Section of this
manual.
HANDLEBAR HEIGHT ADJUSTMENT
The handlebarheight is adjustableto four
different settings. Set the handlebar
heightto a comfortable setting, but keep
in mind that the handlebarswill belower
when the tines are engagedinthe soil.
To AdjusttheHandlebarHeight:

OPERATINGTHETILLER
Thefollowing pagesprovideguidelines to
using your tiller effectively and safely in
various gardening applications. Besure
to read"Tilling Tips & Techniques"in this
Section beforeyou actually putthe tines
into the soil.
This isa traditional "standard rotating
tine" tiller with forward rotating tines. It
operatescompletely differentlyfrom CRT
(Counter RotatingTines) tillers or from
low-cost front tine tillers.
1. Followthe "Pre-StartChecklist" on the
previous page. Besure thatthe Wheel
GearLeveris in the ENGAGEposition.
2. Putthe Depth Regulator Leverin the
"travel" position (leverall the way down)
so that thetines areclear of the ground.
Usethis position when practicing with
your tiller or when moving to or from the
garden. Whenyou are readyto begin
tilling, you must movethe DepthRegula-
tor Leverto the desireddepth setting (see
"Tilling Tips & Techniques").
3. Start the engineand allow itto warm
up. When warm, put EngineThrottle
Control Leverin "FAST"speedsetting.
Keepawayfrom rotatingtines. Rotating
tineswill causeinjury.
4. For forwardmotion of thewheels and
tines:
(a) Pull one or both of the Forward
Clutch Control Levers up and hold
them againstthe handlebars. To
stop forward motion of the wheels
and tines, releasethe levers.
Figure4-2: Useonehandtoguidetiller
whenmovingforward.
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
andtell you if any oftheir equipmentor
lines are buried underground on your
property.
(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
onthe handlebars,but keepyour
arm loose. SeeFigure4-2. Letthe
tiller move aheadat its own pace
and do not push down on the han-
dlebars to try andforce the tiller to
dig deeper- this takesweight off the
wheels, reducestraction, andcauses
the tines to try and propel the tiller.
Do not push down on the
handlebarsto 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
ofcontrol,propertydamage, or personal
injury.
5. Forreverse motion of thewheels and
tines:
(a) Look behind and exercisecaution
when operating in reverse. Do not
till while in reverse.
(b) Stopall forward motion before
reversing. Lift the handlebarswith
onehanduntil thetines are off the
ground and then pull the Reverse
ClutchControl knobout to engage
reversemotion (seeFigure4-3). To
stop reverse motion, let go of the
ReverseClutch Control knob.
Figure4-3: Raise tinesoffgroundand look
behindwhen movingin reverse,
6. To Turn the Tiller Around:
(a) Practiceturning the tiller in a level,
openarea. Bevery careful to keep
your feet and legsawayfrom the
tines.
(b) To makea turn, reducethe engine
speedand then lift the handlebars
until theengine and tines are bal-
ancedoverthe wheels (Figure4-4).
(c) With the tiller balanced,push side-
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 andEngine
1. To stop the wheels and tines, release
the ForwardClutch Controllevers or the
ReverseClutchControl knob (whichever
is engaged).
2. To stop the recoil start engine,move
the EngineThrottle Control Leverto
"STOP". On electricstart models,turn the
ignition keyswitch to "OFF"to stop the
engine.

TillingTips& Techniques
Letthetiller dothework Avoidtilling soggy,wetsoil If thegardensizewill not permit
While tilling, relaxand letthe wheels
pull the tiller along while the tines do
the digging. Walk on the side that is
not yetfinished (to avoid makingfoot-
prints in the freshly tilled soil) and
lightly, but securelygrip 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
helping to hold thetiller back,the tines
will attempt to propel the tiller- often
causingthe tiller to skip rapidly across
the ground. (Sometimes, slight down-
ward pressure on the handlebarswill
help getthrough a particularly tough
section of sod or unbrokenground, but
in most casesthis 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. Use shallow depth reg-
ulator settings (only an inch or two
deep)for thefirst passesthrough the
gardenarea. With eachsucceeding
pass,adjust the depth regulatorto dig
another inch or two deeper. (Watering
the garden areaafew days prior to
tilling will maketilling easier,as will
letting the newly worked soil set for a
dayor two before makinga final, deep
tilling pass.)
Whencultivating (breakingup the
surfacesoil around plantsto help
destroyweeds),usevery shallow depth
settingsto preventinjuryto plantswhose
roots oftengrow closetothesurface. If
needed,lift up onthe handlebarsslightly
to preventthetinesfrom diggingtoo
deeply. (Cultivatingonaregularbasis
notonlyeliminatesweeds,it alsoloosens
andaeratesthesoilfor bettermoisture
absorptionandfasterplantgrowth.)
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 heavyrainsto allow the soil
to dry beforetilling. Test soil by squeez-
ing it into a ball. If it compressestoo
easily, it is too wet to till.
Avoidmakingfootprints
When possible,walk on the untilledside
of the unit to avoid makingfootprints in
thefreshly tilled soil. Footprintscause
soil compactionthat canhamperroot
)enetrationandcontribute to soil
erosion. Theycanalso "plant" unwanted
weedseeds backinto thefreshly tilled
ground.
Choosingcorrectwheel
andtine speeds
With experience,you will find the "just
right" tilling depth and tilling speedcom-
binationthat is bestfor your garden.
Setthe EngineThrottle Control Leverto
a speedto give the engineadequate
)ower and yet allow it to operateat the
slowest possible speed...atleast until
you haveachievedthe maximum tilling
depth you desire. Fasterengine speeds
may bedesirablewhen making final
)assesthrough the seedbedor when
cultivating. Selection of thecorrect
engine speed, in relation to the tilling
depth, will ensurea sufficient power
levelto do the job without causing the
engine to labor.
Suggestedtilling patterns
When preparinga seedbed,go overthe
same pathtwice in thefirst row, then
overlapone-half the tiller width on the
rest ofthe passes(see Figure4-6).
Whenfinished in onedirection, makea
second pass ata right angleas shown
in Figure4-7. Overlapeachpassfor
best results (in very hard ground it may
takethree or four passesto thoroughly
pulverizethe soil).
lengthwiseand then crosswisetilling,
then overlapthe first passesby one-
halfa tiller width, followed bysucces-
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, plusenough extra room for
future plantgrowth.

TillingTips& Techniques
Clearingthetines
Thetines havea self-clearingaction
which eliminatesmost tangling of debris
in the tines. However,occasionally dry
grass, stringy stalks or tough vines may
becometangled. Follow these proce-
duresto help avoidtangling and to clean
thetines, 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 residues or cover
crops while they are green, moist and
tender.
While powercomposting, try swaying
the handlebarsfrom sideto side (about
6"to 12"). This "fishtailing" action
often clears thetines of debris.
If tangling occurs, lift the tines out of
the soil and run the tiller in reversefor
a few feet. This reversing action
should unwind a good deal of debris.
If reversing thetiller doesn't clear the
debris, it may be necessaryto remove
the debris byhand (a pocket knife will
help youto cut away the material).
Beforeclearingthe tines byhand, stop
the engine, allow all moving parts to
stop and disconnect the spark plug
wire. Removethe ignitionkeyon elec-
tric startmodels.
Failure to follow this warning could
resultin personalinjury.
Tillingon slopes
If you must garden on a moderate
slope, pleasefollow two very important
guidelines:
1.Till only on moderate slopes, neveron
steepground wherefooting is difficult
(review safety rules in the "Safety"
Sectionof this Manual).
2.We recommendtilling up and down
slopes ratherthan terracing. Tilling
vertically on a slope allows maximum
plantingarea andalso leavesroom for
cultivating.
IMPORTANT:Whentilling on slopes, be
surethe correct oil levelis maintainedin
the engine (checkevery one-half hour of
operation). The inclineof the slopewill
causethe oil to slant awayfrom its
normal leveland this canstarveengine
parts of required lubrication. Keepthe
engine oil levelat thefull point atall
times!
A. Tilling upanddownslopes:
To keepsoil erosion to a minimum, be
sure to add enough organic matter to
the soil so that it has good moisture-
holding texture andtry to avoid leaving
footprints or wheel marks.
Whentilling vertically,try to makethe
first pass uphill asthe tiller digs more
deeplygoing uphill than it does down-
hill. In soft 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.Terrace Gardening:
Whena slope is too steepor too short
for verticaltilling, it may be necessary
to till across theslope and createter-
racedrows. Terracesare rows that are
cut into the side of a slope, creating a
narrow, but flat areaon which to plant.
Ona long slope, you can makeseveral
terraces, onebelow the other.
Terracesshould be only 2-to-3 feet
wide. Digging too far into the sideof
the slope will exposepoor subsoil that
is unproductive for plants.
To createa terrace, startat the top of
the slope and work down. Goback and
forth acrossthe first row as shownin
Figure4-10.
Eachsucceedinglower terrace is
startedby walking 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 of the downhill
outside edgeof eachterrace. This
untilled strip helps preventsthe ter-
racesfrom breakingapartand washing
downhill. It also provides a walking
path betweenrows.
ol ',
Figure4-10
C. Tilling acrossslopeswithout
usingterraces:
If vertical or terracing gardeningaren't
practicalfor you, then you cantill later-
ally across a slope. We don't really
recommendthis method asit can
createunsurefooting and invites soil
erosion.
As in terrace gardening,startat thetop
of theslopeand overlapthefirst pass
by halfthewidth of the tiller. Foradded
stability of thetiller, always keepthe
uphill wheelin the soft, newly tilled soil.
POWERCOMPOSTING
Powercomposting simply meanstilling
under and burying in the soil all manner
of organic matter such ascrop residues,
leaves,grass clippings and cover crops.
This materialwill decomposeduring the
non-growing season and add 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, move the
Depth Regulator Lever down to 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 begin iswith crop
residues such as leftovervines, stalks,
stems and roots. Powercompost these
crop residues as soonasthey 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.
Standing cornstalks of reasonableheight
can be power composted. Pushing over
(but not uprooting) cornstalkswill often
makeit easierfor your tiller to chop up
the stalks. Keepthe tines clear of exces-
sive tangling by "fishtailing" or frequently
using reverse. Make severalpasses,then
return afew dayslaterto finish off any
remainingstubble.
After tilling under crop residues,add
more organic matter such as leaves,
grass clippings and evenkitchen scraps.
Whentilled into the soil, this organic
matter will decomposeand add even
more important nutrients to the soil.
After powercomposting, you may want to
plant a "green manure" cover crop to
protect the soil during the off-season.You
simply grow a crop of clover, alfalfa,
buckwheat,peas, beans,ryegrass, grain,
or kaleand then till it into the soil prior to
the planting season.
LOADINGANDUNLOADING
THETILLER
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 mustload or unloadthe
tiller, follow theguidelines given next.
Beforeloading or unloading, stop the
engine,wait for all parts to stop moving,
disconnect the spark plug wire and let
the engine and muffler cool. Remove
the ignition keyon electric start models.
Thetiller istoo heavy(over 170 Ibs.,
depending on model) and bulky to lift
safelyby 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 peopleareneeded
to do this.
Ramps must bestrong enoughto
support the combined weight of the tiller
and anyhandlers. Theramps should
provide good traction to preventslip-
ping; they should haveside rails to
guide the tiller along the ramps;and
they should havea locking deviceto
securethem to the vehicle.
Thehandlersshould wear sturdy
footwear that will helpto prevent
slipping.
Position the loading vehicle sothat the
ramp angle isas flat as possible (the
less incline to the ramp, the better).
Turn thevehicle's engineoff and apply
its parking brake.
Whengoing up ramps, stand in the
normal operating position and push the
tiller ahead ofyou. Havea personat
eachsideto turn the wheels.
Whengoing down ramps,walk back-
ward with thetiller following you. Keep
alertfor any obstacles behindyou.
Position a personat eachwheelto
control the speedof thetiller. Nevergo
down ramps tiller-first, asthetiller could
tip forward.
Usewooden blocks to placeon the
downhill sideof the wheels if you need
to stop thetiller from rolling down the
ramp. Also, usethe blocksto temporar-
ily keepthetiller in placeon the ramps
(if necessary),and to chockthe wheels
in placeafter thetiller is in the vehicle.
Whenthe tiller is in the vehicle, prevent
it from rolling byengaging thewheels in
thewheel drive position (put WheelGear
Leverin ENGAGE).Chockthe wheels
with blocks and securelytie the tiller
down.
Maintenance
Before inspecting, cleaning or
servicingthe 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 ignition key on electric
startmodels.
Failure to follow these instructionscan
resultin seriouspersonalinjuryor prop-
ertydamage.

Failure to follow these instructionscan result in serious personal injury or propertydamage.
CHECKFOROILLEAKS
Beforeeachuse, checkyour tiller for
signs of an oil leak- usuallya dirty, oily
accumulation either on the unit or on the
floor where it has beenparked.
A little seepagearound a cover or oil seal
is usually not a causefor alarm. However,
if the 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 fastenersare
tight, a new gasketor oil seal may be
required. If the leakisfrom around a
shaft and oil seal,the oil seal probably
needsto be replaced. Seeyourautho-
rizeddealeror contact thefactory for
service or advice.
IMPORTANT:Neveroperatethetiller if
the transmission is low on oil. Checkthe
oil levelafter every30 hours of operation
and wheneverthere is any oil leakage.
TRANSMISSIONGEAROILSERVICE
Checkthe transmission gear oil levelafter
every30 hours of operation or whenever
you notice anyoil leak. Operatingthe
tiller when the transmission is low on oil
can result in severedamage.
A. To CheckTransmissionGearOil
Level:
1. Checkthegear oil levelwhen thetrans-
mission is cool. Gearoil will expandin
warm operating temperaturesandthis
expansionwill provide an incorrect oil
levelreading.
2. To checkthe gear oil level(and to add
oil, if necessary),referto "STEP5: Check
GearOil Levelin Transmission" in Section
2 of this manual.
B. To Drainand Refill theTransmission:
Thetransmission gear oil doesnot need
to be changedunless it hasbeencontami-
natedwith dirt, sandor metal particles.
1. Prop up the left sideof the unit sothat
it will be securelysupported when the left
sidewheel is removed. Removethe left
sidewheel by removing the wheelmount-
ing hardware.
2. Unscrewthe plasticgear oil fill plug
from the top of the transmission.
3. Placea clean pan belowthetransmis-
sion drain plug (seeFigure5-3) and
remove the drain plug. Theoil will start
flowing out of thedrain hole (it may flow
slowly, especiallyin cold temperatures).
4. Removethe transmission gear oil level
check plug that is locatedafew inches
abovethe left side wheelshaft.
5. Whenthe oil stops flowing, tilt the
transmission forward to drain oil from the
rear of the transmission.
6. After draining the oil, cleanthe threads
of the drain plug, applya non-hardening
removablegasket sealantto the threads,
and securelyreinstall the drain plug.
7. Using a cleanfunnel, slowly add SAE
140 or SAE85W-140 weight gearoil
(with an API rating of GL-4 only)to the
transmission. Thetransmission holds
approximately 3-1/4 pints (52-54
ounces). Tilt thetiller slightly backwards
to makesurethe gear oil reachesthe rear
(tine) endof thetransmission. Stop
adding gear oil when it beginsto flow
from the oil levelcheck hole on the side of
the transmission.
8. Securelyreinstallthe oil levelcheck
plug.
9. Securelyreinstallthe gearoil fill plug
on top of thetransmission.
18. Reinstallthe wheeland remove the
prop.
Sefore 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.

OFF SEASON STORAGE
Whenthe tiller won't be usedfor
extendedperiods,prepare it for storage
asfollows:
1. Cleanthe tiller and engine.
2. Doroutine tiller lubrication and check
for loose parts and hardware.
3. Protectthe engineand perform recom-
mendedengine maintenancebyfollowing
the engine storage instructions found in
the separateEngineOwner's Manual.
NOTE:Besure to protect the fuel lines,
carburetor and fuel tank from gum
deposits byremoving fuel or bytreating
fuel with a fuel stabilizer(follow engine
manufacturer's recommendations).
4. On electric start units, follow "Battery
Storage" instructions in this Section.
5. Store unit in a clean, dry area.
6. Neverstorethe tiller with fuel in the
fuel tank in an enclosed areawheregas
fumes could reachan openflame or
spark,or where ignition sourcesare
present (spaceheaters,hot water heaters,
furnaces, etc.).
BOLOTINES
Thetines will wear with useand should
be inspectedat the beginning of each
tilling seasonand after every 30 operating
hours. Tines can be replacedindividually
or as a completeset. Neverinspect or
servicethe tines unless the engineis
stopped,the spark plug wire is discon-
nected,and the ignition keyis removed
on electric start models.
A. TineInspection:
With use, the tines will become shorter,
narrowerand pointed (Figure5-5). Badly
worn tines will result in a loss of tilling
depthand reducedeffectivenesswhen
chopping up and turning under organic
matter. UseFigure5-5 as a guide to
when the tines should be replaced.
ModerateWear
Replace
Figure5-5: Checkingtinesforwear.
B. Removinga SingleTine:
1. Removethe two screws and nuts that
attacha singletine to the tine holder
(Figure 5-6). If needed,use penetrating
oil to helpfree the nuts.
2. Wheninstalling a single tine, be sure
to position it sothat its cutting edgewill
enterthe soil first as the tiller moves
forward.
C. Removinga Tine Assembly:
1. If removing both tine assemblies,mark
them "left" and "right" before removal.
Doing so will help ensurethat the assem-
blies are reinstalled on the correct sides
of the tiller.
2. Removethe screwand Iocknut that
secure thetine assembly to the tine shaft
(Photo 5-7). Pull thetine assembly off
the shaft (if necessary,usea rubber
mallet to tap the tine assembly outward).
3. Beforereinstalling thetine assembly,
inspect thetine shaftfor rust, rough
spots or burrs and file or sandas needed.
Apply a thin coat of greaseto the shaft.
4. Installeachtine assembly sothat the
cutting edge of the tines will enter the
soil first whenthe tiller moves forward.
Securethetine assembly to the tine shaft
using the screw and Iocknut previously
removed. Tighten securely.
