TILLING AND CULTIVATING
Keepawayfrom rotating tines. Rotating tineswill causeseriouspersonalinjury.
Useyour machinefor busting sod, preparing seedbedsandfor cultivating in gardensand flower beds. It iseasyto op- erate,but it is important thatyou start out slowly and readthis Sectionthoroughly beforeputting it to use. Letthe machine do most of thework. Thetines will pull the machineforward, letting you adjust forward speedby pressing down or lifting
the handlebars.
1. Rollthe machineto the work area.
2. AdJustthetilling depthto the desired
position (see Pre-Start Preparationon the previous page).
3. Start the engine(seeStopping and
Starting the Engineon the previous
page). Standbehind the handlebarand push down on the bar to raise the tines off theground. Squeezethe
Throttle/Tines Lever - the engineshould speedup and thetines start rotating. Re-
leasethe Throttle/TinesLeverto return to idle,the tines should stop rotating or they
may rotate very slowly. Loweringthem backto theground should stop any rota-
tion. NOTE: If tines continueto rotate when
engine is idling, either the idle speedis too high orthe centrifugal clutch is mal-
functioning. If this occurs, contact the Factoryor your localauthorized dealer.
4. Squeezethe Throttle/Tines Leverto
start thetines rotating. Lower the tines to begin tilling. Firmly hold the handlebarto prevent the machinefrom movingfor- wardtoo quickly and to allow enough time for the tinesto dig deeply enough.
AdJustenginespeedto suit the tilling conditions. Rememberthat the rotating tines helpto pull the machineforward. Useslower speedsand a shallow depth setting when learning to use the unit and wheneveryou are tilling on hard,rough or unevenground.
5. Do not try to till too deeply inthe first pass through sod or very hardground. If the machinejumps or bucks, use a shal- lower depth setting andreducethe engine speed. With eachsucceeding pass, till
more deeply.
6. Applydownward pressureon the han- dlebarsfor shallower tilling. Lift the han- dlebarsto dig moredeeply. If the ma- chinestays andtills in one spot, try
swinging the handlebarsfrom sideto side to start it moving forward again.
7. Foreasiertilling, water very hard soil a few days before tilling. Avoidworking the soil when soggy or wet. Wait aday or two afterheavy rain for the ground to dry.
Cultivating
1. Cultivating is shallowtilling that dis-
rupts weedsandaeratesthe uppercrust of soil.
2. Do not till deeperthan 1"-2"to avoid injuring nearby plant roots. Cultivate often, so that weeds do not grow large and causeneedlesstangling in thetines.
3. With carefulplanning,you canspace the seedrows far enoughapart to allow
sufficient room for the machineto culti- vate after the plants havegrown.
AdJustingTine Positions
Dependingupon the tilling project, you havea choice of three tine patterns:
Wide (Standard) Tine Positions- As shippedfrom the factory, the unit is set up for generaltilling andcultivating. This 10"widetine pattern (the maximum tilling
width) usesall four tine sections (A, Figure7). See TineRemovaland In-
stallation in Section 5 for detailed informa- tion on howto set up this tine position.
C
Narrow Tine Positions- Fora narrow, 4-1/2"tilling width, removethe outside
tine sectionon the left- and right-sides
(B,Figure7). SeeTineRemovaland In- stallationin Section5 for detailedinforma-
tion on how to set up this tine position. StonySoil TinePositions- When tilling
deeply in stony soil, stones may become
jammed betweenthe inner tines and the
machinehood. This setupswapsthe two innertines to minimizejamming (c, Figure7). See TineRemovaland/nstalla-
tion in Section 5 for detailed information
on howto set up this tine position.
Tilling Patterns
1. Tomakeseedbeds, go over the same pathtwice in the first row, then overlap
one-half the machinewidth on eachsuc- cessive pass until all rows are tilled twice
(D, Figure 8).
D E
Figure8:RecommendedTillingPattern.
2. Make a second passat a right angle across theoriginal passes. Again, overlapeach pass (E,Figure8). Hard ground maytakethree to four passes
beforethe desired depth is achieved. NOTE:Forsmall gardens,overlap by
one-half (1/2) the machinewidth, fol-
lowedby successivepasses at one-
quarter (1/4) machine width. Thisover-
lapping method assuresthorough tilling.
Making Border Edges
Usethe EdgerAttachmentto makeclean,
sharp edgesnext to walkways, driveways,
paths,plantedareas, patios, etc. SeeIn-
stalling and Using the EdgerAttachment,
in this Section,for detailed information.

INSTALLINGANDUSING THEEDGERATTACHMENT
Contact with rotating tines or other
moving parts can cause serious per-
sonalinjury.
Before installing or removing attach-
ments,or adjustingor servicingthe ma- chine, stop the engine, let all moving parts come to a complete stop, discon-
nect the spark plug wire and move the wire away from the sparkplug.
Tocreate borders or edgesnearwalks, driveways,flower beds,etc., you must
remove the four tine sectionsand install the EdgerAttachment (thisattachment
was supplied with the unit - see Section 3).
Installing the EdgerAttachment
1. Gathertogether the following parts:
Border/EdgerTine (A,Figure 10); Long Bushing (B); Border/EdgerWheel (C); and Short Bushing (D).
2. Prop the machinecarefully onto the front of the tubular carrying handle. The
work surfaceshould befirm andflat. NOTE:Typically,the Border/EdgerTine is
mounted on the right side of the unit for right-handed people,and on the left-side
of the unit for left-handedpeople.
3. Flipopen and remove thetwo ring lock pins (E, Figures9 and 10) oneachtine
shaft.
Figure9: Ringlockpin andtines.
Keepleft and right-side tines separateand markedfor easierreinstallation.
IMPORTANT:Thering lockpin is under spring tension - usecarewhen removing or replacingthe ring lock pin.
4. It is important for propertilling perfor- mancethat thetine sections be later rein-
stalled in their original positions. There-
fore, markthe positionof eachtine section
(Left-Outer,Left-Inner,etc.)beforere- moving them. Referto Figure7 for tine
position information.
5. Install the short bushing (D, Figure10) onto the tine shaft. Thenplacethe Border/Edgerwheel (C) onto the same
shaft - the wheel hub should facetoward
the tiller. Insert the ring lock pin through the rounded side of the tine shaft and
snapthe ring down over the shaft (see "DETAIL",Figure10).
6. Slidethe long bushing (B, Figure 10) onto the opposite side shaft. Theninstall
the Border/Edgertine (A) and secure it
with the ring lock pin.

ArrangingTines
for Narrow Tilling
1. Prop the machineforward so it rests
on the front of thetubular carrying handle. Thework surface should beflat
and firm.
2. Flipopen the ring (A, Figure12) on the left sidering lockpin and removethe ring lock pin.
IMPORTANT:The ring lockpin (A,Figure
12) is under spring tension - usecare when removing or replacingthe ring lock pin.
Figure13:Narrowtillingtineconfiguration.
Arranging Tines for Stony Soil
1. Prop the machineforward so it rests
on the front of the tubular carrying handle. Thework surface should beflat andfirm.
2. Removethe ring lock pin (A, Figure12) from both sides of the unit. Removeboth
outer tine sections. Besure to markeach section asa left or right side tine and
whether it is aninner or outer section.
3. Removethe innertine sections and swap their positions (the inner right-side
section goesonto the left sideof the ma- chine, and the inner left-side goes onto
the right side of the machine).
Do not tamper with the engine governor screwwhich isfactory-setfor the proper enginespeed. Overspeedingthe engine beyond the factory high speed setting can be dangerous and will void the engine warranty. Authorized service
shallbe soughtif a problem exists.
If the engineis equippedwith aspark arrester,clean it everyyear.
Clean,check or adjust the following
items according to the instructions in the EngineOwner's Manual:fuel tank, fuel filter, clutch shoes, idlespeed,valve
clearanceand fuel tubes.
TINE REMOVAL AND INSTALLATION
Thetines wearwith use and should be re- placedif tilling takes longer than usual or
if the soil does not mix thoroughly. In ad- dition to the standard 10"tilling width tine pattern,the tines canbe arranged in a
narrow, 41/2" tilling width pattern for smaller areas,and a special pattern for stony soil conditions.
Figure 12: Standardwide tinepattern and ring lockpin location.
3. Removethe outer tine section (do not remove inner tine section) andmark it as
to which side it is from (left or right) and
whether it'san outer or inner tine section.
4. Slide oneof the long bushings(B, Figure13), provided with the unit, onto
the shaft. Insertthe ring lockpin through the rounded side of the tine shaft and
snapthe ring down over the shaft (see DETAIL- RingLock Pin,Figure10, in
Section 4).
5. Repeatthis procedure on the opposite side.
Figure 14: Stonysoiltine pattern.
4. Reinstallthetwo outer tine sections onto the sides from which they were re-
moved (Figure 14).
5. Insert the ring lock pins through the rounded side of the tine shafts and snap the rings down over the shafts(see DETAIL- RingLock Pin,Figure10, in

old tine sections and replacethem with newtine sections. Referto Figure12 and thetine position shown in the Parts List for tine positioning details. Insert the ring
lock pinsthrough the rounded side of the tine shafts and snap the ring over the shaft (seeDETAIL- RingLock Pin,Figure 10, in Section4).
STORAGE
Never storeyourequipmentwhenthere isfuel inthefuel tank.
Never place yourequipment near any sourceof sparks or open flame (such as from a hot water heater, a space heateror clothesdryer).
Failure to comply can result in serious personalinjury or propertydamage.
IMPORTANT:It is important to prevent
gum depositsfrom forming in essential
fuel systemparts such ascarburetor,fuel filter, fuel hose, or tank during storage.
Also, experienceindicatesthat alcohol- blendedfuels (calledgasoholor using
ethanolor methanol)can attractmoisture which leadsto separationand formation
of acids during storage. Acidic gascan damagethe fuel system of anenginewhile in storage.
Off-SeasonStorageProcedure
Protect the engineand perform recom- mendedenginemaintenanceby fol- lowing the engine storage instructions
found in the separateEngineOwner's
Manual. NOTE:Besure to protectthe fuel lines,
carburetor and fuel tank from gum de- posits by removing the fuel or by
treating the fuel with a stabilizer. See
EngineOwner'sManualfor more infor- mation.
Removetines. Cleanall soil anddebris
from dust coversand tine shaft. Lubri-
catetine shaft with light oil. Replace
tines.
