2. Removethe oil levelcheck plug (M,
Figure2-10) on the left-side of the trans-
mission. (Dueto dried paint onthe plug
threads, it may require some force to
removethe plug thefirst time.) The gear
oil level is correct if oil starts to flow out
of the hole as the plug is removed. If so,
securelyreinstallthe plug.
Figure2-1O:Gearoilleve/checkplug.
3. If oil doesnot flow from the check
hole,addoilas follows:
NOTE:Donot useautomatic transmission
fluid or motor oil in the transmission.
{a) Clean areaaround the fill hole (N,
Figure2-11) and unscrewgearoilfill

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.
FORWARD CLUTCH CONTROL
Thetwo interconnected levers (B, Figure
3-1) control the engagementof forward

To Operatethe ForwardClutchControl:
1. Beforeengaging the Forward Clutch
Control, put the Wheel GearLever in the
ENGAGEposition (see "WARNING"
below).
2. Pullup and hold one or both of the
levers against the handlebargrips to
engagethewheelsand tines.
3. ReleaseBOTHleversto disengage
(stop) the wheels andtines. All forward
motion will stop (the enginewill continue
to run).
Never engagethe wheels and tines with
the Forward Clutch Control or the
Reverse Clutch Control unless the
Wheel Gear Leveris in ENGAGE.
Engagingthe ForwardClutch Controlor
the Reverse Clutch Control when the
wheels are not engagedcouldallow the
tines to rapidly propel the tiller forward
or backward.
Failure to follow this warning could
result in personal injury or property
damage.

anyobstacles,and then pull the Reverse
ClutchControl knob out. Thetinesand
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).
Figure3-2: Depth RegulatorLever,
The highest notch (lever all 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,dependingonsoil conditions.
Forbest results, alwaysbegintilling at
a veryshallowdepthsettingand gradu-
ally increasethe tilling 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 be lower
when the tines are engagedin the soil.

OPERATINGTHE TILLER
Thefollowing pagesprovideguidelines to
using your tiller effectively and safely in
various gardening applications. Besure
to read"Tilling Tips & Techniques"inthis
Section beforeyou actually put the tines
into the soil.
This is a traditional "standard rotating
tine" tiller with forward rotating tines. It
operatescompletely differently from CRT
(Counter Rotating Tines) tillers or from
low-cost front tine tillers.
1. Followthe "Pre-Start Checklist" on the
previous page. Besure that the Wheel
GearLeveris in the ENGAGEposition.
2. Putthe Depth Regulator Leverinthe
"travel" position (lever all 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. When you are readyto begin
tilling, you must movethe DepthRegula-
tor Leverto the desired depth setting (see
"Tilling Tips & Techniques").
3. Startthe engineandallow itto warm
up. When warm, put EngineThrottle
Control Lever in "FAST" speedsetting.
Keepawayfrom rotatingtines. Rotating
tineswill causeinjury.
4. For forwardmotion of the wheels 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.
Page 13

Figure4-2: Useonehandtoguidetiller
whenmovingforward.
(b) Asthe tiller moves forward, 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. SeeFigure 4-2. 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, and causes
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 result in 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) Stop all forward motion before
reversing. Lift the handlebarswith
onehand until 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 tines offgroundand 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 legs awayfrom the
tines.
(b) To makeaturn, reducethe engine
speedandthen lift the handlebars
until theengineand tines are bal-
ancedoverthe wheels (Figure 4-4).
(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.
Stoppingthe Tiller andEngine
1. To stop the wheels and tines, release
the ForwardClutch Control levers or the
ReverseClutch Control knob (whichever
is engaged).
2. To stop the recoil start engine,move
the EngineThrottle Control Lever to
"STOP". On electric start models,turn the
ignition keyswitch to "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
andtell you if any of their equipmentor
lines are buried underground on your
property.

TillingTips& Techniques
Letthetiller dothework Avoidtillingsoggy,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 making foot-
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 takes the weight off
the powered wheels, causing them to
losetraction. Without the wheels
helping to hold the tiller 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 deeply too
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 the first passesthrough the
gardenarea. With eachsucceeding
pass,adjustthe 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 makingafinal, deep
tilling pass.)
• Whencultivating (breakingup the
surfacesoil around plantsto help
destroyweeds),useveryshallowdepth
settingsto preventinjury to plantswhose
roots oftengrow closetothesurface. If
needed,liftuponthe handlebarsslightly
to preventthe tinesfrom diggingtoo
deeply. (Cultivatingona regularbasis
notonlyeliminatesweeds,it alsoloosens
andaeratesthesoilfor bettermoisture
absorptionandfaster plantgrowth.)
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
)enetrationand contribute to soil
erosion. Theycan also "plant" unwanted
weedseedsbackinto the freshly tilled
ground.
Choosingcorrectwheel
andtinespeeds
With experience,you will find the "just
right" tilling depth and tilling speed com-
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...at least until
you haveachievedthe maximum tilling
depth you desire. Fasterengine speeds
may bedesirable when making final
)assesthrough the seedbedorwhen
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 of the passes(see Figure4-6).
Whenfinished in onedirection, makea
second pass ata right angleas shown
in Figure 4-7. Overlapeachpassfor
best results (in very hard ground it may
takethree or four passesto thoroughly
pulverizethe soil).
lengthwiseandthen crosswisetilling,
then overlap the first passesby one-
halfatiller 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, plus enough extra room for
future plantgrowth.

TillingTips& Techniques
Clearingthetines
Thetineshavea self-clearing action
which eliminates most tangling of debris
in the tines. However,occasionally dry
grass, stringy stalks or tough vines may
becometangled. Follow these proce-
duresto help avoid tangling and to clean
thetines, if necessary.
•To reduce tangling, set the depth regu-
lator deepenoughto get maximum
"chopping" action asthe tines chop the
materialagainst the 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(apocket knife will
help youto cut away the material).
Beforeclearingthe tines by hand, 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
resultinpersonalinjury.
Tillingon slopes
If you must garden on a moderate
slope, pleasefollow two very important
guidelines:
1.Till only on moderate slopes, never on
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
plantingareaandalso leavesroom for
cultivating.
IMPORTANT:When tilling onslopes, be
surethe correct oil level is maintainedin
the engine (checkeveryone-half hour of
operation). The incline of the slope will
causethe oil to slant awayfrom its
normal level and this canstarveengine
parts of required lubrication. Keepthe
engine oil level at thefull point atall
times!
A. Tilling upanddown slopes:
• 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:
• Whenaslope 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 side of
the slope will exposepoor subsoil that
is unproductive for plants.
•To createaterrace, start at the top of
the slope and work down. Goback and
forth acrossthe first row as shown in
Figure4-10.
• Eachsucceedinglower terrace is
startedby walking below the terrace
you're preparing. Foraddedstability of
the tiller, always keepthe uphill wheel
in the soft, newly tilled soil. Do not till
the last 12" or more of the downhill
outside edgeof eachterrace. This
untilled strip helps preventsthe ter-
racesfrom breakingapartandwashing
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 can till later-
ally across a slope. We don't really
recommendthis method as it can
createunsurefooting and invites soil
erosion.
•As in terrace gardening,startat the top
of the slopeandoverlapthefirst pass
by half thewidth of the tiller. For added
stability of thetiller, always keepthe
uphill wheelin the soft, newly tilled soil.
Page 16

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
settingifthe tiller 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
resultinpersonalinjury.
Thefirst placeto begin is with crop
residues such as leftovervines, stalks,
stems and roots. Powercompost these
crop residues as soon astheyfinish
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) 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. Make severalpasses,then
return afew days laterto finish off any
remainingstubble.
After tilling under crop residues,add
more organic matter such as leaves,
grass clippings and even kitchen scraps.
Whentilled into the soil, this organic
matter will decomposeand add even
more important nutrients to the soil.
After power composting, 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 recommenddoing so unlessabso-
lutely necessary,as this could result in
personalinjuryor propertydamage.
However, if you mustload or unloadthe
tiller, follow the guidelines given next.
• Beforeloadingor 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 keyonelectric 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 the tiller into and out 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 the vehicle'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 person at eachwheelto
control the speedof the tiller. Nevergo
down ramps tiller-first, asthe tiller 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 chock the wheels
in placeafter thetiller is in the vehicle.
• Whenthe tiller is in the vehicle, prevent
it from rolling byengagingthewheels in
thewheel drive position (put Wheel Gear
Leverin ENGAGE).Chockthe wheels
with blocks and securely tie the tiller
down.

Figure5-1: Lubricationpoints.
Proper lubrication of the tiller isanessen-
tial part of your maintenanceprogram.
After every 10 operating hours, oil or
greasethe lubrication points shown in
Figure5-1 asdescribed below.
Usea good quality lubricating oil (#30
weight engine oil is suitable) and a good
quality generalpurpose grease(grease
that has a metal lubricant is preferred, if
available).
• Removewheels, cleanwheel shaft (A,
Figure5-1) andapply thin coating of
greaseto shaft.
• Greaseback,front and sides of depth
regulator lever (B, Figure5-1).
• Removetines, cleantine shafts (C,
Figure5-1) and inspect for rust, rough
spots or burrs (especiallyaround
holes). Fileor sandsmooth and coat
endsof shaft with grease.
• Oilthe threads on the handlebarheight
adjustment screw (D, Figure5-1).
• Oilthe threads on the handlebarattach-
ing screws (E, Figure5-1).
CHECKHARDWARE
At leastevery 10 operating hours, check
the unit for looseor missing hardware
(screws, bolts, nuts, hairpin cotters, etc.).
Looseor missing hardware can leadto
equipmentfailure, poor performance or
oil leaks.
Besure to checkthe three end cap
mounting screws located at the rear of the
transmission (Figure5-2). Lift the tine
flap to servicethosescrews.
Figure5-2
CHECKTIREPRESSURE
Checkthe air pressure in both tires.
Deflateor inflate both tires evenlyto 15-
to-20 PSI (pounds per squareinch). Be
surethat both tires havethe same air
pressure or the unit will tend to pull to
oneside.

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. J
Remove the key from the keyswitch on units soequipped. J
Failure to follow these instructionscan result in serious personal injury or propertydamage.
CHECKFOROILLEAKS
Beforeeach use, 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 leak can
result in severetransmission damage.
If a cover is leaking,try tightening any
loosescrewsor bolts. If the 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 the factory for
service or advice.
IMPORTANT:Neveroperate thetiller 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. Checkthegearoil levelwhen the trans-
mission is cool. Gearoil will expand in
warm operating temperaturesand this
expansionwill provide an incorrect oil
levelreading.
2. To check the gear oil level (and to add
oil, if necessary),referto "STEP5: Check
GearOil Level in Transmission" in Section
2 of this manual.
B. To Drainand Refill theTransmission:
Thetransmission gear oil doesnot need
to be changedunlessit hasbeencontami-
natedwith dirt, sandor metal particles.
1. Prop up the left sideof the unit so that
it will be securelysupportedwhen the left
sidewheel is removed. Removethe left
sidewheel by removing the wheelmount-
ing hardware.
2. Unscrewthe plasticgearoilfill 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, especially in 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 securelyreinstallthe drain plug.
7. Using a clean funnel, 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 makesure the gear oil reachesthe rear
(tine) endof thetransmission. Stop
adding gear oil when it begins to flow
from the oil level check hole on the side of
the transmission.
8. Securelyreinstall the oil levelcheck
plug.
9. Securelyreinstall the gearoil fill plug
on top of thetransmission.
18. Reinstallthe wheel and remove the
prop.

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. Protect the 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 by removing 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. Neverstore the tiller with fuel in the
fuel tank in an enclosed areawheregas
fumes could reachan openflame or
spark,or where ignition sources are
present (spaceheaters, hot water heaters,
furnaces, etc.).
BOLOTINES
Thetineswill wear with useand should
be inspectedat the beginning of each
tilling seasonandafterevery30 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. Tine Inspection:
With use, the tines will become shorter,
narrowerand pointed (Figure 5-5). Badly
worn tines will result in a loss of tilling
depthandreducedeffectivenesswhen
chopping up and turning under organic
matter. UseFigure 5-5 as a guide to
when the tines should be replaced.
ModerateWear

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 so that its cutting edge will
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 ensurethatthe 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,use a rubber
mallet to tap the tine assembly outward).
3. Beforereinstalling thetine assembly,
inspect the tine shaft for rust, rough
spots or burrs and file or sand as needed.
Apply a thin coat of greaseto the shaft.
4. Install eachtine assembly so that 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.

CHECKINGAND ADJUSTING
TENSION ON CLUTCH BELTS
Maintaining correct belt tension is impor-
tant to good tilling performanceand long
belt life. A loose belt will slip on the
engine and transmission pulleysand
causethe tines and wheels to slow down
- or stop - eventhough the engine is
running at full speed. A loose belt will
also result in premature beltwear.
While checking belt tension, also check
for cracks, cuts or frayed edges.A belt in
poor condition should be replaced.

BATTERYMAINTENANCE
Use extreme caution when working on
or near batteries. To help preventper-
sonalinjuryor propertydamage:.
• Batteries generate explosive gases.
Keepsparksand flames away fromthe
batteryat all times. Ventilate the area
when chargingorusingthe battery in
an enclosedarea.
BatteryCare in Service
The battery is sealedand is maintenance-
free. Acid levels cannot be checked.
• Always keepthe battery cablesandter
minals cleanandfree of corrosive
build-up.
• After cleaning the batteryandterminals,
apply a light coat of petroleum jelly or
greaseto both terminals
• Always keepthe rubber boot positioned
overthe positive terminal to prevent
shorting.
Charging
If the tractor hasnot beenput into usefor
an extended period of time, chargethe
batterywith an automotive-type 12-volt
chargerfor a minimum of one hourat six
amps.
JumpStarting
IMPORTANT:Neverjump your tiller's
dead battery with the batteryof a running
vehicle.
1. Connectend of onejumper cableto the
positive terminal of thegood battery, then
the otherendto the positiveterminal of
the dead battery.
2. Connectthe other jumper cableto the
negativeterminal of thegood battery,
then to the frame of the unit with the dead
battery.
Failureto use this procedure could cause
sparking, and the gas in either battery
could explode.
Cleaning
Cleanthe battery by removing it from the
tractor and washing with a baking soda
and water solution. If necessary, scrape
the battery terminals with a wire brush to
remove deposits. Coat terminals and
exposed wiring with grease or petroleum
jelly to prevent corrosion.
BatteryFailures
Some common causes for battery failure
are:
• incorrect initial activation
• undercharging
• overcharging
• corroded connections
• freezing
IMPORTANT:Thesefailures are NOT
covered by your tractor's warranty.
BatteryRemovalandInstallation
When removing and installing the battery,
disconnect and connectthe cablesin this
order to avoid sparking:
1. To removethe battery, first disconnect
the negative(-) cablefrom the grounding
screw on the back of the battery bracket
post. Bendthe cableawayfrom any metal
parts.
2. Disconnectthe negative (-) cablefrom
the negative(-) battery post.
3. Disconnectthe positive (+) cable from
the positive (+) battery post and bendit
awayfrom anymetal parts. Coverthe
cableterminal with its rubber boot.
4. Removethe battery clamp.
