STEP6: Check Gear Oil Levels

Your tiller has two separatetransmis-

sions: one for the Power Unit (Figure 2-

12), the other for the Tine Attachment

(Figure 2-13). Both transmissions were

filled at the factory with SAE#85W-140

weight gear oil (with an A.P.I rating of

GL-4). Check level in both transmis-

sions to verify that they are still correct.

SeeSection 5, Transmission GearOil

Maintenancefor complete information

on how to check and fill the transmis-

sions.

Section2: Assembly

IMPORTANT: Check gear oil level in both

transmissions after the first 2 hours of

new tiller operation, then every 30

operating hours thereafter. SeeSection 5

for instructions.

Figure 2-12: Checking oil level on

Power Unit Transmission.

Figure 2.13: Checking oil level on

Tine Attachment Transmission.

STEP 7: Add Motor 0il to Engine

I. Beforeadding motor oil, park the tiller

on level ground. Levelthe engine by

placing a sturdy block under the tines or

the tines depth regulator bar.

2. Add high-quality, APl-rated motor oil

to engine before starting. Referto the

EngineOwner's Manual provided with

your tiller for detailed information on how

to add motor oil and for motor oil

specifications.

IMPORTANT:

•Change engine oil after first 2 hours of

new operation.

• Check engine oil level every 5 hours of

operation or each use.

STEP 8: Attach Engine Throttle

Lever and Cable

For shipping purposes, the throttle cable,

together with the throttle lever, is wound

around the engine. Carefully unwind the

cable. If the throttle control label is

coveredwith a clear protective coating,

peel it off.

To avoid electric shock from a short

circuit (electric start tillers only), never

allow the throttle cable to touch the

battery. Routecable below the battery,

onthe outsideof the batteryholder.

To attach the throttle lever and cable:

I. Run the throttle cable up the inside

edge of the right handlebarand position

Section2: Assembly

ASSEMBLINGTHE ELECTRICSTARTSYSTEM

The following steps explain how to activate, charge,and install the battery on electric start tillers. For your safety, follow all steps

and observeall accompanying safetymessages. Section 5 contains other generalbattery maintenanceand recharging instructions.

STEP 1: Activating and

Charging the Battery

IMPORTANT: The battery is shipped dry.

It needs battery electrolytic fluid (battery-

grade sulfuric acid). It must then be fully

charged with a battery charger before

use,

Adding electrolytic fluid to the battery and

charging the battery can be dangerous.

Electrolytic fluid contains acid that can

burn or blind you. Battery charging also

produces explosive gases.

To ensurethat the battery is properly

activatedand charged, you should review

these instructions with your battery

technician.

IMPORTANT: It is strongly recom-

mended that you have the battery

activated and charged by a trained profes-

sional (Troy-Bilt Dealer, service station,

farm equipment dealer, etc.), if you are

not experiencedwith these procedures.

Battery electrolytic fluid is

poisonous and burnsseverely.

Electrolytic fluid is a sulfuric acid

solution. Avoid spills or contact with

skin, eyes, clothing.

•To prevent accidents,wear protective

clothes, rubber gloves and shield

eyes with safety goggles when

workingonor nearthe battery.

•Neutralize acid spills with a baking

soda and water solution. Neutralize

electrolyte container with same

solution. Thenrinse with clear water.

•Antidote: External- Flush with water;

Eyes- Flushwith water for 15 minutes

andget immediate medical attention.

• Antidote: Internal- Drink large

quantityof water or milk. Follow with

milk of magnesia, beaten eggs, or

vegetable oil. Call a doctorimmedi-

ately.

Batteryproducesexplosivegases.

• Keep away sparks, flames, and

cigarettes.

• Ventilate area when chargingor using

batteryin an enclosedspace.

•Make sure batteryvent tube is always

open after batteryis filled with acid.

TOACTIVATETHEBATTERY:

Remove metal jewelry before working

near the battery or near the electrical

system. Failure to comply maycause a

short circuit, resulting in electrical

burns, a shock, or battery gas

explosion.

For shipping purposes, the battery and its

hold-down clamp (A, Figure 2-16) were

installed backwards at the factory. When

reinstalling the battery and hold-down

clamp, be sure to facethem in the

opposite direction from which theywere

shipped.

Figure 2.16: Batteryshown installed

backwardsfor shippingpurposes amy.

I. Removethe two I-I12" long screws

and the two I/4" whiz nuts that securethe

front and rear hold-down clamp legs to

the battery bracket (C, Figure 2-16).

Lift off the clamp and removebattery.

Savethe hardware.

2. If installed, remove anddiscard the

short, plastic tubing (B, Figure2-16) that

covers the vent fitting on the negative-

side of the battery.

3. Place the battery on a levelwork

surface,far awayfrom heat or flame

sources like stoves, water heaters,dryers,

and furnaces.

4. Removethe six filler caps (D, Figure

2-17) on top of the battery.

IMPORTANT: Be sure to wearing protec-

tive clothes, rubber gloves, and eye

protection.

5. Fill each cell to the Upper Level line

printed on the battery case (E, Figure2-

17) using battery-grade electrolytic

solution. (This is 1.265 specific gravity

sulfuric acid.) Temperature of battery and

electrolytic fluid is idealwhen between

60°F and 80°F. Donot add water or any

other liquid to the battery during this

initial activation.

Figure 2-17: Illustration shows filler

caps (D) and Upper Level fill line (E).

6. Let battery stand for 30 minutes.

Check electrolytic fluid level in each cell.

Add more fluid, if needed=Do not overfill

battery - this could leadto flooding from

the cells during charging=

Section2: Assembly

TOCHARGETHEBATTERY:

1. Useone of the three charging methods

described below for maximum starting

capacityand longest battery life.

NOTE:Bubbling (gassing freely) elec-

trolyte solution within the battery cells

indicates that the battery is charged.

Thesebubbles emit toxic gasesthat

escapefrom the cells when you remove

the cell caps. Always wear safety goggles

to protect your eyeswhen checking for

bubbles. A flashlight makes the inspec-

tion easier. Inspect all cells.

To Avoid Personal Injury or Property

Damage:

• Batteries produce explosive gases -

always keep sparks and flame away

from battery.

• Ventilate area when chargingor using

the battery.

•During charging, do not leave battery

unattended. Charging time need not

be continuous.

•Follow safety rules and instructions

supplied by battery and charger

manufacturers.

•Do not charge battery at a rate higher

than 12 amperes to avoid generating

excessive heat and gassing which

coulddamagethe battery.

• Our RecommendedMethod:

Chargethe battery at a rate of 14o-2

amperesuntil all cells bubble freely. Do

not exceed24 hours charge time.

•First Alternative Charging Method:

Chargethe battery at a rate of 440-6

amperesuntil all cells bubblefreely. Do

not exceed8 hours chargetime.

•SecondAlternative Charging Method:

Chargethe battery at a rate of

6-to-12 amperesuntil all cells bubble

freely. Do not exceed4 hours charge

time.

2. Turn offthe charging equipment and

disconnect the charger cables from the

battery terminals.

3. Recheckelectrolyte level in each cell.

Top off any low cells with electrolyte

solution up to the "Upper" level line.

4. Securelyreplace all six filler caps. Use

a baking soda and water mixture to rinse

off electrolytic fluid that may have spilled

on the battery.

STEP 2: Connect the Wire

Harness Receptacle

I. Before installing the battery and its

hold-down clamp, insert the plastic wire

harness receptacle (A, Figure 2-18) into

the prongs of the keyswitch (B) located

on the hold-down clamp.

2. Removethe ignition keys from the

keyswitch and store them safelyaway=

Do not insert the key into the keyswitch

until you complete this section and read

Section 3, Controls.

STEP 3: Installing the Battery

1. Carefully place the activatedbattery

back on the battery mounting platform

(C,Figure 2-18). Facethe side of the

battery with the terminals posts and the

fill lines to the rear of the tiller. The

positive terminal (marked +) should be on

the left side of the tiller when standing

behindthe handlebars.

To Avoid Personal Injury or Property

Damage:

•Do not touch positive battery terminal

and any surrounding metal objects

with tools, jewelry or other metal

items. Failure to comply couldcause

a short circuit leading to electrical

burnsor explosionof batterygases.

• Never bring a gas can near the positive

(+) battery terminal. A short circuit

couldoccur leading to an explosionof

the gasoline or the battery gases.

Always fill the engine fuel tank from

the front or side of the engine.

2. Placethe battery hold-down clamp (D,

Figure 2-18) over the battery. Usetwo

screws (H) and whiz nuts (I) to secure the

two legs to the platform (C). Insert the

screws up from the bottom. Tighten the

hardware but do not overtighten. (The

clamp tabs will bend if screwsare over-

tightened.)

Improper battery venting can cause a

battery to explode resulting in severe

personal injury. Be surethe vent tube is

notcrimped, pinched,folded, or blocked

inany way.

3. To install the vent tube (E, Figure 2-

18), slide one end of the tube over the

vent fitting (F)=Uncoil the tube and slide

the other end down into the black vent

tube shield (G).

Neverjump start the battery with a

functioning properly. Always test the

system before using the tiller or PTO

powerunit.

2. Test the ForwardInterlock Safety

System. See TestingForward Interlock

System, this Section.

Keepaway from rotatingtines. Rotating

tineswill cause injury.

3. When practicing, setthe Depth

Regulator Leverto Travelposition=

Otherwise, set the Depth Regulator Lever

to a desired depth.

4. Move Tines/PTOClutch Leverto

ENGAGEposition if you want the tines to

turn. If practicing, leavein DISENGAGE.

IMPORTANT: Do not move Tines/PTO

Clutch Lever to ENGAGE unless

Wheels/Tines/PTO Drive Lever is in

NEUTRAL.Tiller damagemay occur!

5. To movethe tiller forward and engage

the tines, squeezeand hold either Forward

Interlock Lever (Figure 4-3) against the

handlebargrip, then move the

WheelslTineslPTODrive Leverdown to

FORWARDposition=

Figure 4.4: Guide tiller with one hand.

Section4: Operation

Figure 4-3: Moving tiller forward:

squeeze one Forward Interlock Lever

and then move WheelslTineslPTO

Drive Lever down to FORWARD.

6. When the tiller moves forward, relax

and let the wheels power the tiller along

while the tines dig. Walk behind and to

one side of the tiller. Walk on the side

that is not yet tilled (Figure 4-4). Usea

firm grip on the handlebars but keepyour

arm relaxed.

IMPORTANT: Let the tiller move aheadat

its own pace. Do not push it ahead--this

reduces operator control and tilling effi-

ciency. Do not push handlebars down in

an attempt to dig deeper-- this takes

weight off the wheels, reduces traction,

and causes the tines to try to propel the

tiller.

Stopping Forward Motion and Tines

1. To stop forward motion, tap

Wheels/Tines/PTODrive Lever upward

into NEUTRAL=Then releasethe Forward

Interlock Levers. The wheels and tines

will stop and the engine will continue

running.

2. In an emergency,releaseall of the

control levers. This stops forward motion

and shuts-off the engine.

To Help Avoid Personal Injury or

Damageto Equipment:

•Be sure no obstaclesare behind you

before operatingthe tiller in REVERSE.

•Disengage the tines, reduce engine

speed, and move the Wheel Speed

Lever to SLOW position before

operating in REVERSE. Avoid using

FAST wheel speed until you are

familiar withbackingthe tiller.

Moving the Tiller in Reverse

IMPORTANT: Do not till while in

REVERSE.

1. Shift the TineslWheels/PTODrive Lever

(Figure 4-2) into NEUTRALand move the

Wheel SpeedLever to the SLOW position.

2. Move Tines/PTOClutch Lever (Figure

4-2) into DISENGAGEposition.

3. Verify that the areabehind you is clear.

4. Lift up the handlebarsuntil the tines

are off the ground, then shift the

Wheels/TineslPTODrive Lever all the way

up andhold. You do not needto squeeze

the Forward Interlock Leversto use

reverse.

5. The unit immediatelyengages in

reverse. Periodically check behind you

while holding the handlebars up and the

Wheels/Tines/PTOLever in its upper-most

position.

Stopping Reverse Motion

Releasethe Wheels/Tines/PTODrive

Lever- the lever automatically returns to

the NEUTRALposition. This stops the

wheels immediately. (TheForward

Interlock Leverswill not stop REVERSE

motion.)

To Stop the Engine

Move the engineThrottle Lever to the

STOPposition. Then,on electric start

models, turn keyto OFF. Remove the key

for safekeeping.

Making Turns

Turning the tiller is easyandjust requires

practice. First find the balancepoint

betweenthe engine and the tines by lifting

upthe handlebars (Figure4-5). Onceyou

find the balancepoint, then let the

powered wheelsdo the turning as you

push sideways on the handlebars in the

direction of the turn. Practice the turning

maneuverdescribed herein a large open

area. Once comfortable turning the tiller,

you can then take it to the garden area.

I. At the endof a row, move the Wheels/

Tines/PTODrive Lever (Figure 4-2) to

NEUTRALposition and reducethe engine

speed.

2. Move the Tines/PTOClutch Lever

(Figure 4-2) into the DISENGAGE

position.

3. Resume forward operation, and lift

handlebarsuntil tines are off the ground

(Figure 4-5). Find the balancepoint

betweenthe engine and the tines. Then

push the handlebars in the direction of the

turn. Be very careful to keep feet and legs

awayfrom the tines (which should be dis-

engaged). Let the powered wheels do the

hardwork. The inside wheel will pivot in

placewhile the outside wheel drives the

tiller around in the direction of the turn.

Figure 4.5: Turning the tiller.

NOTE: Use REVERSEif necessaryto turn

in a limited space.

Section4: Operation

4. When the turn is complete, shift to

NEUTRALand lower the handlebars.

Move Tines/PTOClutch Lever backto

ENGAGEposition and resume forward

operation.

TransportingThe Tiller Around

YourProperty

When the engine is running, the tiller's

powered wheels makemoving the tiller to

andfrom the garden easy. If the engine is

not running set the Wheel SpeedLever to

FREEWHEELposition to roll the tiller to

another location.

To help avoid personal injury from

revolving tines, always put the

Tines/PTO Clutch Lever in DISENGAGE

positionbefore transporting,loading, or

unloadingtiller.

1. Placethe Tines/PTOClutch Lever in

DISENGAGEposition.

2. MoveDepthRegulatorLeverdown all the

way into the Travelsetting.

3. If using enginepower, move Wheel

SpeedLever to either SLOWor FAST,and

use the Wheels/Tines/PTODrive Leverto

drive the wheels.

4. If the engine is stopped, move Wheel

SpeedLever to FREEWHEEL,and

manually push tiller.

Testing the Forward

Interlock Safety System

The Forward Interlock Safety System is

designed to shut the tiller engine off

immediately if you lose control and

cannot stop moving FORWARDby

shifting the Wheels/Tines/PTODrive Lever

into NEUTRAL. When you releaseboth

Forward Interlock Levers,they send

ground to the ignition system thereby

stopping the engine. Squeezingone or

both levers up againstthe handlebars

enablesthe ignition system; therefore,

you must squeezeat least one lever

whenever the Wheels/Tines/PTODrive

Lever is engagedin FORWARD.

IMPORTANT: The interlock system also

prevents the engine from starting if the

Wheels/Tines/PTODrive Lever is engaged

in FORWARD.

The ForwardInterlock Safety System is

designed for the operator's safety. Do

not disconnector attempt to defeat the

purpose of the system. If the system

malfunctions,immediately contactyour

local authorized dealer or the

TROY-BILT Technical Service Depart-

ment for assistance. Do not use the

tiller or the PTO power unit until the

Forward Interlock Safety System is

functioning properly. Always test the

system before using the tiller or PTO

power unit.

How to Check the Interlock System

The Forward Interlock System has an

electro-mechanical design, and so is

subject to normal wear and possible mal-

function. Checkthe system for proper

operation each time prior to using the

tiller or PTOpower unit.

Figure 4.6: Plug and receptacle of

Forward Interlock Safety System

must be securely connected.

To test the Forward Interlock System:

1. Movetiller outside to level ground.

Removeany obstacles.

2. Checkthat the Forward Interlock wire

harnessplug, at the bottom of the handle-

bars (Figure4-6), is securely connected

to the receptacleon the top, right side of

the transmission.

3. MoveWheel SpeedLever (Figure 4-2)

to SLOW position and move Tines/PTO

Clutch Lever to DISENGAGE.

4. Start engine as described under

Starting and Stopping the Engine,in this

section. Set engine throttle lever to

SLOW,and let enginewarm up.

5. Squeezeand holdjust one of the

Forward Interlock Leversagainst the

handlebargrip while moving the Wheels/

Tines/PTO Drive Lever down to

FORWARD(Figure 4-3). As the tiller

moves forward, releasethe ForwardInter-

lock Lever briefly. The engineshould

start to stall out if the interlock system is

working properly. If it does start to stall,

quickly squeezethe lever up against the

handlebargrip, and then return the

Wheels/Tines/PTO Drive Lever to

NEUTRAL. Repeatthis test to check that

the engine begins to stall out when the

other ForwardInterlock Lever is released.

6. If the enginedoes not begin to shut off

when either Forward Interlock lever is

released,shut the engine off, removethe

key (if electric start), anddo not operate

the tiller or PTOpower unit until the

systemhas beenrepaired and is func-

tioningproperly.

IMPORTANT: To avoid possible damage

to the ForwardInterlock Safety system,

do not use high-pressure sprays nearthe

wire harness receptacleor neutral plunger

assembly.

Loading and Unloading the Tiller

The following provides information on

tiller loading,unloading, and requirements

before loading and unloading the tiller,

Readthe following instructionscarefully

before attempting to load or unloadyour

tiller.

Before Loading or Unloading the

Tiller

•Ramps must be strong enoughto

support the combined weight of the tiller

and handlers. Theyshould provide good

traction to prevent slipping; they should

have side rails to guide the tiller along

the ramps; andthey should have a

locking deviceto secure them to the

vehicle.

• Handlers should wear sturdy footwear

that will helpto preventslipping.

Section4: Operation

•Turn the vehicle's engineoff and apply

its parking brake.

• Position the loading vehicleso that the

ramp angle is as flat as possible (the

less incline to the ramp, the better).

Loading the Tiller

I. Use loading ramps that are strong and

wide enough to safely hold the weight of

the tiller andthe operator combined--

your tiller weighs between280 and 325

Ibs.

2. Move the Tines/PTOClutch Lever

(Figure 4-2) into DISENGAGEposition.

3. Set the Depth Regulator lever (Figure

4-2) to the Travel position.

4. Move Wheel SpeedLever (Figure4-2)

into SLOWposition and reduce the

engine throttle speed.

5. Shift the Wheels/Tines/PTOLever

(Figure 4-2) into FORWARDposition and

follow the tiller up the ramps (Figure 4-7).

Checkthe wheels as you move the tiller

forward. Ensurethat they move up the

center of each ramp.

6. Preventtiller from rolling in vehicle.

LeaveWheel Speed Lever in FASTor

SLOW position, chock wheels with blocks

and tie down the tiller.

Figure 4.7: To go up ramps, use

FORWARD drive.

Unloading the Tiller

IMPORTANT: Neverunload the tiller in

FORWARDdrive. The tiller could tip

forward and exposeyou to the tines

(which should be disengaged as

instructed).

I. Use loading ramps that are strong and

wide enough to safely hold the weight of

the tiller andthe operator combined--

your tiller weighs between280 and 325

Ibs.

2. Move the Tines/PTOClutch Lever

(Figure 4-2) to DISENGAGEposition.

3. Set the Depth Regulator Lever (Figure

4-2) to the Travel position.

4. Move Wheel SpeedLever (Figure 4-2)

to SLOWposition and reduce the engine

throttle speed.

IMPORTANT: Look behind you before

you back down the ramp to ensure that all

is clear. While descending, keepchecking

for obstacles behindyou.

5. Move and hold the Wheels/Tines/PTO

Lever into REVERSEdrive and backdown

the ramps (Figure 4-8). Checkthe wheels

as you move the tiller backward. Ensure

that they move down the center of each

ramp.

Figure 4-8: To go down ramps, use

REVERSE drive.

Changing Speed Belts

Your tiller has two belt-driven speed

ranges - HIGH RANGEand LOW RANGE

- you pick one or the other by deciding

which set of pulley grooves to move the

forward belt into. By moving the belt

from onespeed range into the other, in

combination with the FASTand SLOW

wheel speeds,you obtain a choice of four

different forward wheel speedsand two

different tine speeds.

To help avoid serious personal injury,

stop the engine, remove the ignition

key, disconnect spark plug wire and

move the wire away from the spark

plug, and let engine and muffler cool

downbefore changingbelt speeds.

Changing the belt from LOW range into

HIGH range (or backagain) is a matter of

moving the belt from one set of pulley

grooves to asecond set of pulley grooves.

This change is done quickly and without

tools (Figures4-9 through 4-13).

Pulley

Figure 4.9: Be/t range positions.

When the tiller is moving in REVERSE,the

wheels are powered by a rubber reverse

disc, not by the belt. Therefore, you have

only two reversespeedsSLOW and FAST,

as set with the Wheel SpeedLever.

Table 4-I shows the rangeof wheel and

tine speeds availablewhen using the two

belt speed ranges andthe FASTand

SLOWselectionson the Wheel Speed

Changing Belt From LOW Range

to HIGH Range

1. To avoid personal injury, shut off

engine, let all moving parts come to a

complete stop, then disconnect spark

plug wire from spark plug and move it

awayfrom spark plug before making any

adjustments. Wait for the engineand

muffler to cool down.

2. Move WheelslTines/PTODrive Lever

into NEUTRAL.

Section4: Operation

The HIGH speed belt range position

combined with a FAST wheel speed

setting propels the tiller at the fastest

pace. Reducethe enginethrottlespeed

whenstartingoutto help avoid personal

injury or propertydamage if using this

speedcombination.

3. Kneelon left side of tiller. To create

belt slack, reach over to right side of the

pulleys and push in at the center of the

belt with a finger. At the sametime, use

your left hand to work the belt part-way

onto the lower-front transmission pulley

groove (Figure 4-10).

Figure 4.10: Low range to high range.

Shows moving belt from lower.rear

groove onto lower-front groove.

4. Goto the other side of the tiller to

finish seating the belt onto the pulley

groove.

5. Working from the left side of the tiller,

work the belt as much as possible onto

the top-front engine pulley groove (Figure

4-11).

6. Finish seatingthe belt from the right

side of the tiller.

IMPORTANT: Proper belt tension is

important for good performance. See

Section 5, Drive Belt Maintenance for

information on belt maintenance schedule

and procedures.

NOTE: If extra belt slack is needed to

move the belt, just raise the

Wheels/Tines/PTO Drive Lever up into

REVERSE. This lowers the engine pulley,

and creates more slack.

Figure 4-11: Low range to high

range. Shows moving belt from top-

rear groove onto top.front groove.

7. Checkboth sidesof the high range

pulley grooves to verify that the belt is

properly seated.

Changing Belt From HIGH Range to

LOW Range

1. To avoid personal injury, shut off

engine, let all moving parts come to a

complete stop, then disconnect spark

plug wire from spark plug and move wire

awayfrom spark plug before making any

adjustments. Let engineand muffler cool.

2. Move the Wheels/Tines/PTODrive

Lever into NEUTRAL.

3. Stand on left side of tiller. Useyour

right hand to hold the Wheels/Tines/PTO

Drive Lever up into REVERSEposition.

Useyour left handto move the belt off

top-front engine pulley groove to top-rear

engine pulley groove (Figure 4-12).

Figure 4.12: High range to low

range. Shows moving belt from top-

front groove onto top-rear pulley

groove.

4. Goto right side of tiller and finish

seating the belt.

5. Still holding the lever up in REVERSE

position, andworkingfrom the left side of

the tiller, move the belt from the lower-

front transmission groove to the lower-

rear transmission groove.

6. Goto the right side of the tiller and

finish seating the belt (Figure 4-I 3).

Figure 4.13: High range to low

range. Shows moving belt from

lower-front onto lower-rear groove.

7. Checkthat the belt is fully seatedin the

pulley grooves. Checkthis from both

sides of the tiller.

Choosing Wheel

andTine Speeds

Your tiller has four FORWARDwheel/tine

speed combinations for handling a variety

of tilling tasks and gardeningjobs. Exper-

iment with the tine depth, enginespeed,

and wheel/tine speed and determine the

combination that provides the best

results. Hereare some tips:

1. Advancethe throttle lever so the engine

has sufficient power.

2. When tilling untilled or hard earth, do

not set the Depth Regulatortoo deep. The

tiller will buck andthe enginewill load

down.

3. You will know your settings are ideal

when the tines break-up the soil easily,

the enginedoes not labor, and your

progress is steadyand smooth.

Tilling Tips& Techniques

Let the tiller do the work

•While tilling, relax and let the wheels

pull the tiller along while the tines do

the digging. Walk on the side that is not

yet finished (to avoid making footprints

in the freshly tilled soil) and lightly, but

securely grip the handlebarwithjust

onehand (Figure 4-4).

• Avoid pushing down on the handlebars

in an attempt to force the tiller to dig

deeper. Doing so takes the weight off

the powered wheels, causing them to

lose traction. 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

downward pressure on the handlebars

will help get through a particularly

tough section of sod or unbroken

ground, but in most cases this won't be

necessary.)

Tilling depths

•Avoid trying to dig too deeply too

quickly, especially when busting sod or

tilling soil that hasn't been tilled for

some time. Useshallow depth settings

(only an inch or two deep)for the first

passesthrough the gardenarea.

With each succeeding pass, adjust the

depth regulator to dig another inch or

two deeper. (Watering the gardenarea

afew days prior to tilling will make

tilling easier,as will letting the newly

worked soil set for a day or two before

making a final, deeptilling pass.)

• When cultivating (breakingup the

surfacesoil around plantsto help

destroy weeds), use very shallowdepth

settingsto preventinjury to plantswhose

rootsoften grow closeto the surface. If

needed,lift upon the handlebarsslightly

to preventthe tinesfrom diggingtoo

deeply. Cultivatingon a regularbasisnot

only eliminatesweeds,it also loosensand

aeratesthe soil for battermoisture

absorptionandfasterplant growth.

Avoid tilling wet, soggy soil

Tilling wet soil often results in large, hard

clumps of soil that can interfere with

planting. If time permits, wait aday or

two after heavyrains to allow the soil to

dry before tilling. Test the soil by

squeezingit into a ball. If it compresses

too easily, it is too wet to till.

To help avoid personalinjury, be aware

that the tiller can unexpectedlybounce

up orjump aheadand propelawayfrom

you if the tines strike hard or frozen

ground, or buried obstacles like large

stones, roots or stumps. Always use

the following precautions to help

maintaincontrolof the tiller:

•Walk behind and to the side of the

tiller. Use onehandonthe handlebars,

relaxing your arm but with a secure

handgrip.

•Use shallowdepth regulatorsettings.

Till graduallydeeper.

•Use slower wheel, tine and engine

speeds.

• Clear the tilling area of all large

stones, rootsandotherdebris.

•Do notput downwardpressureon the

handlebars. If needed, apply slight

upwardhandlebarpressureto keep the

tinesfrom diggingtoodeeply.

• Avoid contacting hard soil or sod at

the end of a row -reduceengine speed

and lift handlebarsto raise tines out of

the soil.

• In An Emergency, stop tines and

wheels by moving Wheels/Tines/PTO

Drive Lever to NEUTRAL. If youcannot

roachthe lever or have lostcontrol, Let

Go OfThe HandlebarsandAll Controls. 23

Section4: Operation

TillingTips& Techniques

Avoid making footprints

When possible,walkon the untilled side

of the unit to avoid making footprints in

the freshly tilled soil (Figure 4-4). Foot-

prints causesoil compactionthat can

hamper root penetrationand contribute

to soil erosion. Theycan also "plant"

unwantedweed seedsbackinto the

newlytilled soil.

Suggestedtilling patterns

•When preparing a seedbed,go over

the same path twice in the first row,

then overlap one-half the tiller width

on the rest of the passes (Figure 4-

14). When finished in one direction,

makea second pass at a right angle as

shown in Figure 4-15. Overlapeach

passfor best results (in very hard

ground it may take three or four

passesto thoroughly pulverizethe

soil).

• If the garden sizewill not permit

lengthwise and then crosswise tilling,

then overlap the first passes by one-

half atiller width, followed by succes-

sive passesat one-quarter width

(Figure 4-I 6).

• With planning, you can allow enough

room between rows to cultivate

(Figure 4-17). Leaveroom for the

hood width, plus enough extra room

for future plant growth.

Tilling onslopes

If you must garden on sloping ground,

pleasefollow two very important guide-

lines:

I= Till only on moderateslopes, never

on steep inclines where footing is

difficult (review safety rules in the

"Safety" Section of this Manual).

2. We recommend tilling up and down

slopes rather than terracing. Tilling

vertically on a slope allows maximum

planting areaand also leavesroom

for cultivating.

IMPORTANT: When tilling on slopes,

be sure the correct oil level is main-

tained in the engine (check every one-

half hour of operation)= The incline of

the slope will causethe oil to slant away

from its normal level and this can starve

engine parts of required lubrication.

Keepthe engineoil level at the full point

at all times!

A. Tilling up anddown 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.

• When tilling vertically, try to makethe

first pass uphill as the tiller digs more

deeply going uphill than it does

downhill. In soft soil or weeds, you

may haveto lift the handlebars slightly

while going uphill. When going

downhill, overlap the first pass by

about one-half the width of the tiller.

HINT: For best results, use the HIGH

belt rangeand SLOW wheel speed lever

position. SeeChanging SpeedBelts in

this section for more information on

changing to high range.

To avoid serious personal injury or

damage to the equipment:

•Do not operate tiller on a slope too

steep for safe operation. Go slowly

on any slope. Make sure you have

goodfooting.

•Wear footwear that increases

stabilityandreducesslippage.

•Do not use FAST wheel speed

positionwhenon slopedground.

•Do not shift the Wheel Speed Lever

when heading up or down a slope. If

lever is accidentally moved to FREE

WHEEL position, the tiller could roll

out of control.

•To preventenginedamage due to oil

starvation (on slopes,the engine is

inclined and oil moves away from

surfaces that need lubrication), be

sure the correct oil level is main-

tained during all uphill/downhill

tilling operations. Checkthe level of

the oil in yourengine after every one-

half hourof operation.

Section4: Operation

TillingTips& Techniques

Clearing the tines

The tines have a self-clearing action

which helps to eliminate most tangling

of debris. However,occasionally dry

grass, stringy stalks or tough vines may

becometangled.

Followtheseprocedures to help avoid

tanglingandto clear the tines, if

necessary.

Figure 4.18

B.Terrace Gardening:

•Whena slope is toosteep or too short

for verticaltilling, it may be necessary

to till across the slope and create

terracedrows. Terracesare rows that

are cut intothe side of a slope,creating

a narrow, but flat areaon whichto

plant.

• On a long slope, you can makeseveral

terraces, one below the other.

• Terracesshould beonly 2-to-3 feet

wide. Digging too far into the side of

the slope will expose poor subsoil that

is unproductive for plants.

• To createa terrace, start at the top of

the slope andwork down, Go backand

forth across the first row as shown in

Figure 4-18,

• Eachsucceeding lower terrace is

started by walking below the terrace

you're preparing. Foradded stability of

the tiller, always keep the uphill wheel

in the soft, newlytilled soil. Do not till

the last 12" or more of the downhill

outside edge of each terrace. This

untilled strip helps prevents the

terraces from breaking apart and

washing downhill. It also provides a

walking path betweenrows.

C. Tilling acrossslopes

withoutterracing

• If vertical or terracinggardening aren't

practical for you, then you can till

laterallyacross a slope, We don't

really recommend this method as it

can create unsure footing and invites

soil erosion.

• Study the terrain to makecertain the

slope is not too steepfor safetilling.

If possible, maketerracedrows or till

vertically.

• Move the belt into LOW belt range and

the Wheel SpeedGearLever to SLOW

position. As in terracegardening, start

at the top of the slope and overlap the

first pass by half the width of the tiller.

Foraddedstability, keep the uphill

wheel in the soft, newly tilled soil. Each

succeeding terraced areais started by

walking belowthe terrace you are

preparing (Figure 4-19).

Beforeclearing the tines by hand, stop

the engine, allow all moving parts to

stop and disconnect the spark plug

wire. Failure to follow this warning

couldresult in personal injury.

• To reduce tangling, setthe Depth

Regulatordeepenough to get

maximum "chopping" action as the

tines chop the material against the

ground. Also, try to till under crop

residues or cover crops while they are

green, moist and tender.

• While power composting, try swaying

the handlebarsfrom side to side (about

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

often clearsthe tinesof debris.

• It may be necessaryto removethe

debris by hand (apocket knife will help

you to cut awaythe material).

Figure 4.19: Make a terrace in just 4

or 5 passes with the tiller.

Section4: Operation

TillingTips& Techniques

POWERCOMPOSTING

Power composting meanstilling under

and burying in the soil all manner of

organic matter such as crop residues,

leaves,grass clippings and cover crops.

This material will decompose during the

non-growing seasonand add important

natural nutrients to the soil.

After tilling under crop residues, add

more organic matter such as leaves,

grass clippings and even kitchen scraps.

When tilled into the soil, this organic

matter will decompose andadd even

more important nutrients to the soil.

After power composting, you maywant

to plant a "green manure" cover crop to

protect the soil during the off-season.

I. As you move forward into a row of

stalks, aim the tiller so that the stalks go

betweenthe left wheel andthe transmis-

sion case (Figure4-19). Do not use the

right wheel becausedamage could occur

to the air cleaner, carburetor or throttle

linkage.

When power composting,do not keep

the Depth Regulator Lever at adeep

setting if the tiller jumps or bucks.

If jumping or bucking occurs, move

the Depth Regulator Lever down to

one of the shallower settings and

then slowly increase the tilling depth

on later passes.

Failure to complycould result in loss

of tiller control, property damage or

personal injury.

Begin by composting crop residues such

as leftover vines, stalks, stems and

roots. Power compost these crop

residuesas soon as they finish bearing.

The sooner this is done, the better, as

tender green matter is easier to till

under. Usethe deepestdepth regulator

setting possible without causing the

engineto labor or the tiller to jump

ahead.

Standing cornstalks of reasonableheight

can be power composted (Figure 4-20).

Pushing over (but not uprooting) corn-

stalks will often makeit easierfor your

tiller to chop up the stalks. Keepthe

tines clear of excessivetangling by "fish-

tailing" or frequently using reverse.

Makeseveral passes,then return a few

days later to finish off any remaining

stubble.

Grow a crop of clover, alfalfa,

buckwheat, peas,beans, rye grass,

grain, or kaleand then till it into the soil

prior to the planting season.

Wide-Row Planting

The wide-rowplanting technique is

spreading seedsanywherefrom 10

inchesto 2 feet wide or more. As a

result, you can grow anywherefrom 3 to

4 times (or more) produce in the same

spacethat is normally set asidefor an

areathat has narrow, single rows.

Wide-row planting automatically shades

the ground which keepsweed growth

down and also holds moisture in the

soil. And of course, harvesting is much

easier - everything is right at hand to be

picked. Preparing wide rows is easy --

after you preparethe seedbedand mark

off the rows with string, hand-broadcast

the seeds as if seeding a lawn (not quite

as much as lawn seed). Coverwith soil

andtamp the areafirmly with a hoe.

Tilling Under Corn

After corn is harvested,the stalks should

be tilled into the soil while still green.

Dry plants aremore difficult to till under,

andthe roots break loose too easily.

IMPORTANT: Do not pull the roots out

by hand or cut the stalks before tilling.

Stalks that are firmly anchored by their

roots are much easier for the tines to

to a complete stop, disconnectsparkplug wire and move wire away from sparkplug. Remove ignition

key, if so equipped.

Failure to followthese instructionscanresult inseriouspersonalinjury or propertydamage.

Tighten Bolts and Nuts

Checkfor loose or missing hardware

every ten (10) operating hours. Failureto

tighten or replacefasteners can cause

poor performance, equipment damageor

oil leakage. Seeyour PartsCatalogfor

complete fastener descriptions.

Most hardware on your tiller is visible.

Pay particular attention to hardware

shown in Figures5-1, 5-2, 5-3 and 5-3A.

I. Checkthe transmission pulley

mounting bolt (Figure 5-I). If the washer

behind the bolt headis loose, the bolt

needs tightening. To do this, first insert a

punch or thick screwdriver into the hole

next to the bolt and wedge the tool

against the side of the motor mount

casting. This immobilizes the pulley while

you tighten the bolt.

2. Checkjam nut on left side of neutral

plungerassembly(Figure5-2). If loose,

immobilize bolt headwith one wrench and

use another wrench to tighten the nut.

3. Checkthe three rear bearingcap

screws under the depth regulator

mounting bracket (A, Figure 5-3). If any

is loose, it can causean oil leakor drive

shaft end play.

4. Checkthe five bolts securing the tiller

housing coverto the left side of the trans-

mission (B in Figure 5-3). Gearoil can

leakfrom a loose housing cover. To

reach the bolts, remove the left side tine

holder. SeeBolo TineMaintenancein this

Section for tine holder removal directions.

5. Check both swing-bolts (C, Figure5-3)

that connect the power unit transmission

to the tine attachment. Both bolts should

be checked every 2-1/2 hours of

operation. If loose,wear can occur on the

locating pin on the power unit, and cause

enlargement of the locating hole in the

tine attachment. Using a torque wrench,

tighten these bolts to 70-to-80 ft.-Ibs.

6. Checkthe Iocknutthat fastens the

shifting linkage to the eccentric shifting

lever (D, Figure5-3). Do not tighten the

Iocknut against the eccentric lever. It

should bevery closeto, but not touching

the lever.

7. Checkthe four bolts and nuts securing

left and right fine holders to the fine shaft

(Figure 5-3A).

Figure 5-1: Check bolt on transmission pulley.

IMPORTANT: Give screws or bolts that

go into the transmission housing a

coating of non-hardening gasket sealant

to prevent gearoil from leaking.

Tiller Lubrication

Proper lubrication of the tiller's mechani-

cal parts is an essential part of good

maintenance. Lubrication should be done

after everyten (10) hours of operation.

Useordinary motor oil (#30 weight or

lighter) where oil is specified. Use a

quality greasewith a metal lubricant

where grease is recommended (regular

grease is acceptable). Do not over

lubricate. If there is a build-up of dirt,

removethe build-up and re-apply oil or

grease.

key, if so equipped.

Fa ure to fo ow these nstructonscan resut n ser ouspersona njuryor propertydamage.

IMPORTANT: Do not allow oil or grease

to contact the pulleys, drive belt or

reverse disc. This can cause the belt or

disc to slip on the pulleys.

Lubricate the numbered areas in Figures

5-4 and 5-5, as follows:

1. Oil the wheel shaft betweenthe wheel

hubs and the transmission housing

(A, Figure5-4).

2. Oil all pivoting and connecting points

on the Wheels/Tines/PTODrive Lever and

the Wheel SpeedLever (B, Figure5-4).

3. Greasethe face of the belt adjustment

block (C, Figure 5-4).

4. Oil the DepthRegulator Lever,

including the spring inthe mounting

bracket(D, Figure5-4).

5. Oil the full length of the throttle cable

casing (E, Figure 5-4).

6. Oil threads on HandlebarHeight Adjust-

ment Lever (F, Figure 5-4).

Figure 5.4: Tiller lubrication points

(wheel removed for clarity).

7. Grease left- and right-side engine

mounting bars at the top, the middle, and

bottom (G, Figure 5-4).

8. Greasethe zerkgrease fitting located

on the pivot point at the end of the Wheel

Speed Lever (H, Figure 5-4). If Wheel

Speed Lever has a greasefitting on pivot

assembly, apply 2-to-3 strokes of multi-

purpose grease at beginning and end of

tilling season.

9. Keepthe PTOaccessareawell-greased

(I, Figure 5-5). If the Tines/PTOClutch

Lever becomes hard to move, squirt some

oil into its accesshole, andwork it back

and forth to disperse the oil.

Transmission Gear

Oil Maintenance

Checking for Oil Leaks

At 25-hour operation intervals, checkthe

tiller for oil leaks. Inspect for oil accumu-

lations on the tiller or the floor where it's

stored.

If tilling during very hot weather, the gear

oil may heat up and expand inside the

transmissions. To allow for this oil

expansion, both the power unit transmis-

sion and the Lineattachment transmis-

sions have oil relief vents (Figure 5-6).

Figure 5.6: Oil relief vent locations.

The vents allow small amounts of oil to

seep out.

If a serious leak is discovered, please

contact your authorizeddealeror the

FactoryTechnical Service Departmentfor

service advice.

A small amount of oil seepageor wetness

around a shaft opening or

cover is no causefor

alarm. But a heavy con-

centration of oil is more

serious. You should

tighten all bolts immedi-

ately, and replace any

worn sealsor gaskets.

Figure 5.5: Use grease liberally in PTO access area.

It may be impossible to

determine how much oil

has been lost, so check the

oil levels in the PTOtrans-

mission and the tine

attachment before using

the tiller again. Add any

necessarygear oil.

Serious damage to the

transmission components

can result from operation

when gear oil levels are

low.

Checking Gear Oil Levels

Every30 hours of operation, check the

gearoil level in both the power unit trans-

mission andthe tine attachment transmis-

sion. Operatingthem while low on gear

oil (even briefly) can cause serious

damageto internal components.

Preparation

I. The transmissionsmustbe cool,

since hot gear oil expandsand gives a

false reading.

2. The power unit transmission andthe

Lineattachment transmission must be

connected when checking (or adding)

gearoil.

Checkingthe Power Unit Oil Level

I. Move the tiller to level ground. Move

the Depth Regulatorup so the tines rest

on the ground.

2. Usea 3/8" wrench to removethe oil

level check plug on the left side of the

transmission housing (Figure 5-7).

Section5: Maintenance

_efore inspecting,cleaningor servicingthe machine, shutoff engine, wait for all movingparts to come

to a complete stop, disconnectsparkplug wire and move wire away from sparkplug. Remove ignition

key, if soequipped.

Failure to follow these instructionscan result in seriouspersonalinjuryor propertydamage.

Figure 5-7: Remove oil level check

plug. Gear oil should seep out if

the level is sufficient

3. If the oil level is correct, oil will seep

out of the check hole (allow extra time in

cold weather). If it does, the level is fine

and you should replace thecheck plug. If

no oil seepsout, seeAdding or Changing

GearOil.

Checkingthe Tine

AttachmentOil Level

IMPORTANT: Two different gear oil

checking procedures for the tine attach-

ment transmission are described next.

Use the first procedure if the dipstick in

your tine attachment has only a 'Check

Cold' marking. Usethe second procedure

if the dipstick has both cold and hot

markings at the end. First remove the

dipstick from the tine attachment trans-

mission (Figure 5-8) to see which type

dipstick you have. Then replace the

dipstick with markings on dipstick facing

to rear.

Figure 5-8: Checking gear oil level;

markings on dipstick (tine attach.

ment transmission) must face rear.

For DipsticksWith 'CheckCold"Marking

(Cold means 2 hours has passed since

the tiller was used.)

I. Move the tiller to level ground.

2. Pull the DepthRegulator Lever back,

then push it down all the way (to engage

its top notch).

3. Place asturdy support under the

engineto prevent the tiller from tilting too

far=

4. Now slide three piecesof 2" x 4"

lumber underneaththe drag bar- raising

the drag bar about 4-112"above ground.

This elevation allows an accurate "cold"

gear oil reading.

5. Wait two hours with tiller elevated

(allow more time if temperature is below

40°F).

6. Loosen and remove transmission

dipstick (Fig.5-8). Wipe it clean with a

rag.

7. Hold dipstick so its markings faceto

rear of tiller. Lower it straight down into

the sump hole to touchthe drive shaft

inside (Fig.5-8). Don't force or try to

thread it back in; an incorrect readingwill

result.

8. Remove dipstick and check oil level. It

should be anywherewithin the cross-

hatched areaor even slightly above the

Max marking. If correct, replace dipstick

and remove the boards used as props.

9. If oil level was low, gear oil must be

added before using the tiller. See Adding

or ChangingGearOil next.

For DipsticksWithHot/ColdMarkings

1. Move the tiller to level ground.

2. Pull the DepthRegulator Lever back,

then push it down all the way (to engage

its top notch).

3. Place asturdy support under the

engineto prevent the tiller from tilting too

far=

4. Cold reading (preferred method):

(Two hours has passedsince the tiller

was used.) Place a 2" x 4" board (on

edge)under the drag bar- raising the tiller

anddrag bar about 3-I12" aboveground.

Hotreading: (Tiller was operatedfor

more than 30 minutes within the past

hour.) Do not use the wood prop to

elevatethe tiller.

5. FollowSteps 4, 5 and6 given for the

other dipstick type.

6. Removedipstick and check level. It

should bewithin or above the "Cold"

rangemarking if taking a cold reading. If

taking a hot reading, the level should be

within or slightly abovethe "Hot" range.

7. If the level is incorrect, see Adding or

Changing GearOil.

Adding or Changing Gear Oil

Forpartial fill-ups (just a few ounces or

less), use SAE140, SAE85W-140, or SAE

80W-90 weight gear oil with an API rating

ofGL-4or GL-5. Forfull replacement,

use SAE140 or SAE85W-140 gear oil

with anAPI rating of GL-4only. (At the

factory, SAE85W-140 weight gear oil is

used.)

IMPORTANT: Do not use automatic

transmission fluid or engine oil. They are

too light in weight and will result in trans-

mission damage=

The gear oil does not needto bechanged.

Do so only if you know, or suspect, it is

contaminatedwith dirt, sand or other

foreign particles.

Gearoil is available at authorized dealers

andmost service stations, power

equipmentcenters, or farm/heavy

equipmentoutlets=

Capacities: Power unit transmission

holds approximately 60 ozs.; Tine Attach-

ment transmission holds approximately

12-112"ozs.

AddingGear Oilto the

PTOPowerUnit Transmission

1. Do steps 1 and 2 of Checking the

Power Unit Oil Levelon page 32.

2. Using a 3/4" wrench(or socket),

remove the bolt securing the handlebar

base to the top of the transmission (prop

the handlebarsfirst to prevent them from

falling).

Then, unplug the Forward Interlock wire

harness receptacleat the bottom of the

handlebars. Set the handlebarbase and

bolt aside on a clean surface. The bolt

hole in the top of the transmission is the

gear oil fill hole (A, Figure 5-9).

3. Slowly pour gear oil through aclean

funnel into the transmission. Stop when

gear oil begins to flow from the oil level

check hole on the left side of the trans-

mission (B, Figure 5-7).

4. Reinstall the oil level check plug.

Tighten it securely.

5. Reinstall the handlebars using the

mounting bolt previously removed. Align

the handlebars so they point straight

backwards, not at an angle. Then tighten

the mounting bolt securely.

6. Reconnectthe Forward Interlock wire

harnessto the receptacle. Be certain it's

secure.

7. Test operation of the Forward Interlock

Safety System. SeeSection 4 for a

procedure.

DrainingandFilling the

PTOPowerUnit Transmission

I. Placea shallow pan under the trans-

mission gear oil drain plug (B, Figure

5-9).

2. Removethe oil levelcheck plug (Figure

5-7) with a 3/8" wrench. This vents the

transmission for faster oil draining.

Figure 5-9: Gear oil fill hole (A) and

gear oil drain location (B).

3. Using the 3/8" wrench, removethe

drain plug (B, Figure8-9). The gearoil

will drain quite slowly since it is thick.

After about two quarts havedrained, tilt

the tillerforward so any oil at the rearof

the transmissionwill drain out.

4. Cleanthe drain plug threads, put non-

hardening gasket sealanton the threads,

and reinstall plug.

5. Refill the transmission with the correct

amount of gear oil before operating the

tiller again. When oil seepsfrom the oil

level check hole, the right amount of gear

oil has beenadded. Replaceall plugs.

AddingGear Oil to the Tine

AttachmentTransmission

1. Selectthe right Depth Regulator Lever

setting:

a. If filling anempty transmission, raise

the Depth Regulator Lever so tines

are on the ground.

b. If topping off the gear oil, move Depth

Regulator Lever down to engageits

top notch.

2. Remove dipstick from fine attachment

(Figure 5-8).

3. Slowly add gear oil in the dipstick hole.

Add I/2-ounce at a time to avoid overfill-

ing. It takesabout 12-I12 ounces.

4. Takedipstick readings frequently. Stop

when oil reaches"Cold" range marking on

dipstick. Replacedipstick securely.

Drainingand Filling the Tine

AttachmentTransmission

I. The fine attachment transmission is

not equippedwith an oil drain plug. To

drainjust a small amount of gear oil,

removethe dipstick and tilt the attach-

ment forward (first uncoupling it from the

Power Unit).

2. For complete drainage, remove the left-

side fine assembly (refer to Bolo Tine

Drive Belt Maintenance

MeasuringandAdjusting

DriveBeltTension

On a new tiller (or if a new belt is

installed), the belt tension will probably

needto be adjusted after thefirst two (2)

hours of operation. Thereafter, check belt

tension everyten (10) operating hours.

Maintaining the right tension is important

to good tiller performance and long belt

life. If too loose, the belt will slip on the

pulleys, and be unableto deliver full

power to the wheels and tines. A loose

belt will also wear prematurely.

While checking belt tension,also inspect

the belt for cuts, cracks, deterioration,

etc. Don't continue using a belt that isn't

in good shape. You're sacrificing tiller

performance by doing so.

Tips on keeping the drive belt in top

condition include:

• Alwaysput the Wheels/Tines/PTODrive

Lever in NEUTRALwhen the tilleris not in

use,

• Keeptensionadjusted correctly.

• Don't "speed shift" when moving the

Wheels/Tines/PTODriveLever between

FORWARDand REVERSE.

Howto Measure Belt Tension

1. Before taking a measurement, besure

the linkages and pivot points on the

Wheels/Tines/PTODriveLever are clean

and lubricated. If there is any binding,

you won't get true measurements. Also,

you'll needthe belt adjustment tool you

receivedwith your new tiller (Figure

5-11).

2. Move the Wheels/Tines/PTODrive

Leverfully down to the FORWARD

position. The clutch roller at the bottom

of the lever should be positioned under-

neaththe belt adjustment block (Figure

5-12). Don't let the clutch roller move

during the next few steps. If it moves,

you'll get a false belt tension reading.

3. The belt tension is correct if the front

of the clutch roller is 1/4"-to-5/16" away

from the faceof the upright bracket that

holds theadjustment block in place

(Figure 5-12). To measurethis distance:

a_ Without moving the clutch roller, try

inserting the 1/4"-thick, slotted end

of the belt adjustment tool in

betweenthe roller and the upright

bracket. (The flat edgeof the tool

must be facing the roller.) Referto

Figure 5-13.

b. If only the slotted portion of the tool

will fit, the belt tension is correct.

c. If the slotted part of the tool will not

fit in, the belt is too loose.

d. If the full thickness(5/16") of the

tool easilyfits in, the belt is too

tight.

Figure 5-11: Use this belt adjust*

ment tool to measure and adjust

drive belt tension.

Figure 5-12: Shift into FORWARD

and measure distance between

roller and upright bracket using the

belt adjustment tool.

4. If the belt tension is correct, move the

Wheels/Fines/PTODrive Lever back to

NEUTRAL.

Figure 5-13: Insert slotted end of

belt adjustment tool between roller

and bracket, with the flat side of the

slotted end facing the roller.

How to AdjustBelt Tension

1. As described in thefollowing steps,

drive belt tensionis adjusted by moving

the adjustment block up or down.

Moving it down will tighten the belt;

moving it up loosens the belt.

HINT: The distance the block moves

approximately equals the distance the

roller moves.

In most cases,the clutch roller will not

have beenvery far out of position, so the

adjustment block will only needto be

moved slightly (up or down)=

2. Move the Wheels/Tines/PTODrive

Lever to NEUTRALposition. The clutch

roller will come to rest anywhereon the

faceof the belt adjustment block,

depending upon drive belt length and

current belt tension adjustment.

Section5: Maintenance

_efore inspecting,cleaning or servicingthe machine, shutoff engine, wait for all movingpartsto come I

to a complete stop, disconnectspark plug wire and move wire away from spark plug. Remove ignition

key, if so equipped.

Fa ureto fo ow these nstructonscan resut n ser ous persona njuryor propertydamage.

3. Insert the belt adjustment tool through

the hole in the side of the adjustment

block, spacing the ends of the tool equally

on both sides (Figure 5-14). Rotate the

tool so the slotted end faces down.

Figure 5-14: With WheelslTineslPTO

Drive Lever in NEUTRAL, insert tool

through hole in adjustment block.

4. Placethe Wheels/Tines/PTODrive

Lever in FORWARDposition. The arms of

the clutch control yoke will be resting on

the belt adjustment tool andthe clutch

roller should be engagedslightly beneath

the adjustment block (Figure 5-15).

Figure 5-15: With Drive Lever in

FORWARD position, clutch roller

should be engaged slightly beneath

the adjustment block.

5. Useone hand to hold the drive lever in

FORWARDwhile using a 9/16" wrench to

loosen (don't remove) the bolt at the back

of the belt adjustment block (Figure 5-16).

The adjustment block should be free to

move either up or down.

Figure 5.16: Hold Drive Lever while

loosening bolt. Push lever down to

tighten belt; pull up to loosen belt.

6. Push the drive lever down if the belt

needstightening. Pull the lever up if the

belt needsto be loosened. Hold the drive

lever in place and tighten the bolt in the

adjustment block firmly.

7. Let go of the drive lever and remove

the belt adjustment tool from the hole in

the adjustment block.

8. Check the tensionon the belt by

following the previous instructions "How

to MeasureBelt Tension."

NOTE: If the adjustment block is all the

way down and the measurement between

the clutch roller andthe bracket is less

than 1/4",thena new drive belt is needed.

Replacing the Drive Belt

Removingthe Belt

1. Move Wheels/Tines/PTODrive Leverto

Range position shown).

Reverse Disc Inspection

Thereverse disc is made of steelwith a

special, long-lasting rubber compound

bonded to the disc rim. Since this is a

wearingpart, it should be inspectedafter

every 30 operating hours.

1. Measurethe widthof the outside edge

of the disc as shown in Figure 5-22.

Replacethe disc before the rubber edge

wearsto a thicknessof 1/8"or less.

Failure to do so could causethe steel

underneath the rubber to damagethe

transmission pulley.

7. Movethe bottom half of the belt into

the HIGH Rangegroove of the lower

pulley (groove closest to engine-- Figure

5-21). If extra shackis needed,hold up

Wheels/Tines/PTODrive Lever while

moving the belt. Verifythe belt is seated

properly on the pulleys.

8. Tomove the belt to the LOW Range

position, see Changing Belt Speedsin

Section 4.

3. Push belt forward thendown until it is

looped over the lower pulley (Figure

5-18). Do not yet seat it in either of the

lower pulley's grooves.

HINT: A blunt object, like a ruler, can

help you push the belt downward if

needed.

4. Move the top half of the belt up and

over the rubber reversedisc, but do not

seat it in either of the grooves in the top

pulley.

5. Placethe Wheels/Tines/PTODrive

Lever in NEUTRAL.

6. Move thetop half of the belt into the

HIGH Rangegroove (groove closest to

the engine) on the top pulley (Figure

5-21).

9. After installing the belt, check and

adjust for correct belt tension as

explained previously.

Reverse Drive

System Maintenance

Theseinstructions explain how to inspect,

replace or adjust thevarious reversedrive

components,

But first, here's how the reversedrive

system works:When you raise the

Wheels/Tines/PTODrive Lever up in

REVERSEposition, this lowers the rub-

berized reversedisc (it's attached to the

engine drive pulley) until this rotating disc

contacts thetransmission drive pulley=

The friction betweenthe rotating reverse

disc andthe transmissionpulley causes

the transmissiondrive shaft to be

powered in a counterclockwise direction

(asviewed from the operator's position

behind handlebars)=The drive shaft then

turns the wheels and tine shafts in a

reversedirection.

Figure 5.22: Measure the edge of

the reverse disc for wear.

2. Look for big cracks or missing chunks

of rubber from the disc. If so damaged,

the disc should be replaced immediately.

IMPORTANT: Extend the life of the

reverse disc by always pausing in

NEUTRAL before shifting between

FORWARD and REVERSE. Also - the

reverse disc is not suited for continuous

or sustained reverse operation. Use

reverse sparingly.

Section5: Maintenance

_efore inspecting, cleaning or servicingthe machine, shutoff engine, wait for all movingpartsto come I

to a complete stop, disconnectspark plug wire and move wire away from spark plug. Remove ignition I

Replacing the Reverse Disc

Followthese steps to replace the reverse

disc. (If your tiller has a Bumper Attach-

ment mounted, it must be removedfirst.)

Removingthe ReverseDisc

1. MoveWheelsfrines/PTO Drive Lever in

NEUTRALposition.

2. Wedge a 5/16"-thick board betweentop

of engine pulley (avoidcontacting reverse

disc) and cast iron housing next to it.

This immobilizes pulley.

3. Usea 9/16"wrench to loosen the

mounting bolt shown in Figure5-23.

Rememberto immobilize the pulley with

the wood wedge while loosening the bolt.

If necessary,pry the disc from the pulley

with the tip of a screwdriver. Backthe

bolt out as far as possible. Then angle

the disc a little to remove it. Bring the

bolt and Iockwasher along with the disc.

andengine mount move down to press

on the reverseadjustment bolt (Figure 5-

24). This action compresses the reverse

spring and plunger assembly, requiring

you to hold the lever up in REVERSE.

Whenyou releasethe lever,the spring

automatically pushes the lever back into

NEUTRALposition.

The spring and plunger assembly is

designedto preventthe reversedisc from

making contact with the transmission

pulley until you shift into REVERSE.

Whenthe lever is in NEUTRAL,the switch

body on the bottom of the engine mount

tab should be resting squarely on top of

the reverse adjustment bolt (Figure 5-24).

The reverse adjustment bolt can be

adjusted up or down to correct a number

of reversedrive operating problems, as

explainednext.

Figure 5-24: Spring and plunger

assembly.

ment bolt should be adjusted upward (see

instructions thatfollow). Moving adjust-

ment bolt upward will also solve problem

of a tiller that goes into REVERSEon its

own.

Figure 5.25: Checking Reverse

Disc in NEUTRAL.

3. Useyour left hand to hold

Wheels/Tines/PTODrive Lever up in

REVERSE,while briefly pulling out engine

start rope. The reverse disc should turn

lower pulley (see Figure 5-26). If not, or

it requires a lot of pressureto hold lever

up in REVERSE,then reverseadjustment

bolt must be adjusted downward. When

correctly adjusted, the Wheels/Tines/PTO

Drive Lever should pop out of reverse

when the lever is released,but not require

exceptional effort to hold it up in reverse

position.

2. On left side of tiller, put a 1/2" wrench

on the plunger retaining bolt and another

1/2"wrenchon thejam nut next to it

(Figure 5-27). While holding the bolt

steady,loosen thejam nut (counterclock-

wise) until it touchesthe bolt head.

Figure 5.27: Hold bolt steady while

loosening or tightening jam nut.

7. Placea chalk or pencil mark on the top

edge of the plunger retaining bolt. Now,

whilewatchingthe mark, loosen the bolt

3/4-turn (Figure 5-29). Do not exceeda

3/4 turn (this woulddisengagethe bolt

from the locking groove in the side of the

plunger).

Figure 5-28: Loosen jam nut before

turning reverse adjustment bolt.

Bolo Tine Maintenance

Checking Tines for Wear

Inspectthe tinesfor wearor damage after

every 30 operating hours. The rate of

weardepends upon hours of use and soil

conditions. With use, the tinesget

shorter, narrower and more pointed

(Figure 5-30). If badly worn,theylose the

ability to till deeply.

3. Turn the bolt in until it tightens against

the plunger inside the spring, The bolt

must be tight to preventplunger from

turning -but becareful not to overtighten

and break the bolt.

4. Placea 7/8" wrench on the head of the

reverseadjustment bolt and a9/16"

wrench on thejam nut below it (Figure 5-

28), Hold the bolt steady while loosening

thejam nut three or four turns.

5. Move the Wheels/Tines/PTODrive

Leverto NEUTRAL. The switch body on

the bottom of the engine mount tab

(Figure 5-24) should be resting squarely

on top of the reverseadjustment bolt, and

the reverse disc should beat least 3/16"

awayfrom the transmission drive pulley.

If the reverse disc is any closer than this,

raise the reverseadjustment bolt (turn it

counterclockwise).

6. Check that reverse disc is at least 3/16"

awayfrom transmission drive pulley,

Then hold reverseadjustment bolt steady

with onewrench while tighteningjam nut

Failure to follow these instructionscan result in seriouspersonalinjuryor propertydamage.

Tine Shaft Maintenance

After every 10 operating hours, remove

the left- and right-side Bolo Tine holders

and clear away dirt and debris that have

accumulated on the Oneshaft or inside

the Oneholders. Pleasefollow this main-

tenancerecommendation, as debris can

cause prematurewear to the Oneshaft

and its oil seals. Referto the previous

tine holder removal instructions. After

cleaning away any debris and removing

old greasefrom the tine shaft, apply fresh

grease to the tine shaft.

Tire and Wheel Maintenance

Checktire air pressure every 30 operating

hours. The recommended pressurefor

tilling is 104o-20 psi (pounds per square

inch). Both tires should be inflated

equally. (Unequal pressurecan causethe

tiller to pull to one side.)

Removing the Wheels

Eachwheel is secured by a roll (spirol)

pin that passesthrough the wheel hub

and the wheel shaft. Drive the roll pin out

to removea wheel.

1. Prop the transmission up with a sturdy

block to raise the wheel you want to

remove off the ground.

2. Move the Wheel SpeedLever to either

SLOWor FASTposition to prevent the

wheels from turning.

3. Use a5/16" drift pin (or a blunt point

16-penny nail) to drive the roll pin free.

Wear safety goggles when driving the

roll pin into or from the wheel hub to

protectyour eyesfrom the possibilityof

flying metal particles.

Engine Oil Maintenance

Checkthe engine oil level before starting

the engineeach day and after each 5

hours of continuous operation. Running

the enginewhen it is low on oil will

quickly ruin the engine.

It is recommended that you changethe oil

everyten (I0) operating hours and even

sooner when operating in extremelydirty

or dusty conditions. Referto the separate

EngineOwner's Manual for detailed

service instructions.

Air Cleaner Maintenance

The engine is equipped with a dual

element air cleanerthat filters the air

twice before it enters the carburetor to

mix with the fuel.

The engineair cleaner filters dirt and dust

out of the air before it entersthe carbure-

tor. Operating the enginewith a dirty,

clogged air filter can cause poor perfor-

manceand damage to the engine. Never

operate the engine without the air cleaner

installed. Inspectand servicethe air

cleaner more often if operating in very

dusty or dirty conditions.

It is critical that the filters be kept clean

and properly installed at all times. See

the location of the air cleanerassembly on

your engine by referring to Figure5-39 or

Figure 5-40.

Referto the engine manufacturer's litera-

ture supplied with your tiller for complete

air cleaner service and maintenance infor-

mation.

Throttle Cable Maintenance

The throttle lever settings arefactory-

adjusted, so unnecessaryadjustments

should not bemade. However,if the

enginedoes not start or stop, or respond

immediately to various throttle lever

settings, then adjustments may be

necessary. Pleaserefer to the engine

manufacturer literature supplied with your

tiller for specific adjustment instructions.

Ignition System Maintenance

Your engine is equippedwith electronic

ignition. It does not havea condenser or

points, so there is no need to perform any

regular tune-up maintenance on this

system other than adjusting or replacing

the spark plug.

Spark Plug Maintenance

The spark plug must be in good condition

for proper engineoperation. Remove and

inspect the plug every 50 operating hours

or annually, whichever occurs first.

The correct electrodegap is .030". Check

the gap with a feelergauge. Do not use a

spark plug if the porcelain is cracked, the

electrodesare pitted or burned, or if other

visible damage is present.

NOTE: Do not wire brush or sandblast the

spark plug to clean it - loose particles

can enter the engine, causing damage!

To replacethe plug, first tighten it

securely by hand, then use a spark plug

wrench to tighten the plug an extra 114

turn.

Battery Care and Maintenance

Battery Care in Service

I. Everymonth or every ten (10)

operating hours, whichever comes first,

checkthe level of electrolyte solution in

the battery cells:

a. If battery case has UPPERand

LOWERlevel lines on it, solution

should be maintained at the UPPER

level line.

b. If the battery does not havelevel

lines on case, maintain solution

levelat lowest part of the filler well

within eachcell.

NOTE: Use only distilled or demineralized

water to refill eachbattery cell.

c. After filling, replace battery caps

securely,then wash off any spilled

solution with baking soda and water

mixture.

d. Run engineoutdoors for about 20

minutes (at 3/4 throttle) to help

recharge. For safety, do not leave

the tiller unattendedwhile the

engine is running.

Battery Care in Storage

Your engine has a recharging circuit that

will properly maintain the battery's state

of charge during the normal tilling

season. However,prior to storing your

tiller awayduring the off-season, we

recommend the battery be fully charged.

At the end of the storage period, the

battery should be recharged again=

• While the battery is being charged,

do not leave it unattended. Charging

time does nothave to be continuous.

•Carefullyfollow all charging instruc-

tions and safety rules provided by the

manufacturer of the charging

equipment.

• Never attempt to "jump start" the

battery with an automobile battery or

its charging system. This could result

in serious personal injury or property

damage from causes such as a battery

explosion,or acidor electrical burns.

1. Remove battery from tiller (see Battery

Removal instructions) and placeon a

stable, level surface.

2. Cleanbattery if needed. If battery is

very cold, let it warm up to 60-to-80OF.

3. Removefiller caps. Keepthem off

whenfilling andcharging.

4. Carefully check electrolyte level. If low,

add distilled or demineralizedwater (do

not add batteryacid) to bring the

solution level in eachcell up to correct

height. Avoid overfilling.

5. Charge battery (with caps removed)

until all cells are gassingfreely. (To

check for gassing, wear protective

goggles and inspect each cell with flash-

light for bubbling of electrolyte solution.)

Useone of the following methods to

charge battery:

a. RecommendedMethod: charge the

battery at a rate of 1-to-2 amperes

until cells aregassing freely. Do not

exceed24 hours charging time.

b. First Alternative Method: charge battery

at 4-to-6 amperes until cells gas freely.

Do not exceed8 hours charging time=

C_ SecondAlternative Method: charge the

battery at a rate of 6-to-12 amperes

until cells gas freely. Do not exceed4

hours charging time.

Do not charge the battery at a rate

higherthan 12 amperes. A chargerate

greater than this generates excessive

heat andgassing, and will permanently

damagethe battery.

6. When battery is fully charged,turn

charging equipment off and disconnect

the cables. Check electrolyte level in all

cells. Add distilled or demineralizedwater

if necessaryto adjust level to the correct

height. Then reconnectthe charger

cables to the battery and chargethe

battery for one more hour.

Section5: Maintenance

_efore inspecting,cleaning or servicingthe machine, shutoff engine, wait for all movingpartsto come

to a complete stop, disconnectsparkplug wire and move wire away from sparkplug. Remove ignition

key, if so equipped.

Failure to follow these instructionscanresult inseriouspersonalinjury or propertydamage.

7. Replacethe filler caps andwash off

any spilled electrolyte with a baking soda

and water solution.

8. Store the battery in a cool, dry

location. Avoid freezing temperatures.

Batteries lose voltagewhen in storage,

more so in hot weatherthan in cold.

Ideal storagetemperature is 50OF.

Battery Removal and Replacement

1. Disconnect the negative (-) cable from

the grounding screw on the right side of

the battery bracket (A, Figure 5-42) and

bend the cable awayfrom all metal parts.

2. Disconnect negative cablefrom

negative (-) battery post (B, Figure 5-42),

and remove cable.

3. Disconnect positive (+) cablefrom

positive battery post (C, Figure 5-42) and

bend it safely awayfrom metal parts.

Covercable terminal with rubber boot.

4. Removethe battery holddown clamp

and remove the battery.

5. Reversethe previous steps to replace

the battery. The batterypostsmustface

the rear of the tiller. (The positive post

must be on the left side as you face

forward from the handlebars.)

6. Insert the vent tube (on positive side of

battery) into the vent tube shield. Be sure

it is not crimped, pinched or folded along

its length.

When removingthe battery, always dis-

connect the negative (-) cable first

followed by the positive (+) cable. Re-

verse this procedure when reinstalling

the battery.

Storing Your Tiller

When yourtiller won't be used during the

off-season, prepareit for storagewith the

following steps:

1. Cleanthe tiller and engine.

2. Do routine tiller lubrication andcheck

for loose hardware.

Figure 5.42

3. Protect the engine from deterioration

or damage by referring to the engine

storage instructions in your engine

manual literature.

4.When engine is still warm, drain oil

from enginecrankcase. Refillwith flesh

motor oil.

5. Protect internal cylinder against rust by

removing spark plug and pouring one

ounce of clean engine oil into spark plug

hole. Then slowly pull out recoil start

rope 2 or 3 times to distribute oil inter-

nally. Replacespark plug, but do not

reconnect plug wire. Pull rope until resis-

tance is felt -- let rope rewind.

6. Chargebattery (electric start option).

Store battery in cool, dry location.

7. Move Wheels/Tines/PTODrive Lever to

NEUTRALposition. Keeptiller in a clean,

dry area.

8. Neverstore tiller with fuel in fuel tank

in an enclosedareawhere gas fumes

could reach anopen flame or spark, or

where ignition sources are present (space

heaters, hot water heaters,furnaces, etc.).

Inspecting Forward Interlock

WiringSystem

Checkthe Forwardinterlock wiring

system everyten (10) operating hours,

for tight connections and to seethat the

insulation on the wires is unbroken (to

prevent the system from shorting out).

1. Check insulatedwire harnessfrom

lower ends of handlebars to wire harness

connector on top, right side of transmis-

sion cover. Besure connector is secure.

2. Check insulatedtubingfrom connector

to cast iron motor mount/belt shroud.

3. Check the wire leadingfrom the tubing

over to the switch assembly mounted on

top of the tab on the cast iron motor

mount-belt shroud. Also check the

secondwire that leads to the throttle

cable mounting bracket on the right side,

forward portion of the engine.

Testing the Forward

Interlock Wiring System

The wiringcircuit for the Forward

Interlock SafetySystem is designed to

ground out the engine's ignition system.

There are three switches in the circuit

which, when open, let the engine run.

Oneswitch is on the neutral plunger tab

of the cast iron motor mount. This switch

is openwhenever the Wheels/Tines/PTO

Drive Lever is in NEUTRALor REVERSE

positions. The other two switches are

locatedinside the handlebars,directly

abovethe two Forward Interlock Levers.

The switches are wired so when squeezed

(open) the enginewill run. There is a

fourth switch located in the wiring

harnessconnector on the top, right side

of the transmission cover. It warns you if

the connection is not mated by not letting

the engine run while the Wheels/Tines/PTO

Drive Lever is in FORWARD.

1. A broken or disconnectedwire could

let the engine run without you having to

press one of the Forward Interlock Levers.

2. A barewire touching tilleror engine

metal could ground out the engine's

ignition.

3. A switch that has failed allows the

engineto run. Or it may preventthe

enginefrom running.

Referto the Troubleshootingsection if

your Forward Interlock SafetySystem is

not operating correctly. 43

• Key for bronze worm gear on tine attach-

ment main drive shaft may be missing or

broken.

5 Tines Turn, But Wheels Won't:

• Check operation of Wheel Speed Lever

(Problem 2).

• Hi-Pro key inside wheel clutch may be

missing, broken, if so, clutch will not turn

wheel shaft.

• FASTand SLOW speed wheel gears may

be worn. if only one gear is worn, there will

only be one wheel speed.

• Worm gear that drives pinion shaft and

pinion gears may beworn.

• FASTand SLOW speed pinion gears may

be worn. if only one gear is worn, there will

only be one wheel speed.

• Drive "dogs" on sides of wheel clutch may

be worn or broken, if only one side of clutch

is affected, there will only be one wheel

speed.

6Wheels And Tines Turn OnTop Of

Ground, But Stop Or Hesitate In Soil:

• Drive belt may be loose (Sect. 5).

• Mounting bolt for transmission drive pulley

may be loose (Figure 5-1).

7 Tiller Jumps While Tilling:

AppendixB: Attachments& Accessories

Troy-Bilt®PTO Chipper/Shredder

The Troy-Bilt_ PTOChipper/Shredder

provides aconvenient, easy meansof

cleaning up unsightly brush piles and

other organic matter on your property,

with the addedbonus of providing an

unending supply of useful wood chips,

mulch and compost for your landscaping

and gardening needs.

The unit connects quickly to your tiller

and goes wherever your tiller can go. The

swivel wheel on the backof the unit

rotates for extra maneuverability. When

you've finished your chores, the

Chipper/Shredderstands by itself on its

own built-in stand.

The PTOChipper/Shreddercan chip

limbs, stalks and vines up to 3" in

diameter, andcan shred the same

materials up to 1/2" in diameter. The unit

also handles all manner of organic

material including lumber, leaves,grass,

weeds, brush, paper and sod.

Troy-Bilt®PTO Log Splitter

The Troy-Bilt_ PTOLog Splitter provides

you with a convenient and easy meansof

splitting about a half a cord of wood per

hour when working alone. When

connected to the PTOPower Unit, the

tiller's engineruns the splitter's hydraulic

pump, providing you with 13 tons of

steady, unhurried andpredictable splitting

force.

As anadded benefit, the power-driven

mobility provided by the PTOPower Unit

allows you to move the splitter to and

from your wood pile, over to a neighbor's

place,or alongthe woodpile to a fresh

supply of logs.

Featuresinclude a 15 second splitting

cycle; can handlelog sizes up to 26" long;

a two-stage hydraulic pump that automat-

ically shifts into low gearto provide four-

times greater pressurewhen needed;

slim-cut wedge design for splitting green,

stringy wood; and an auto-control valve

for automatic return stroke.

Dozer/Snow Blade Attachment

In the winter, moves up to one foot of

light snow (or 6"-to-8" of heavysnow); at

other times use it to move or spread

sand, gravel, loose dirt, grain, sawdust,

etc. Attacheseasilyto the front of the

Wrap-Around Bumper Guard. Set the

blade to severalangles. Weighs41-1bs.;

measures 15"x 32".

HilleriFurrower Attachment

The most popular attachment becauseit

does so many-jobs. Mounts to the rearof

the depth regulator bracket. Furrower

blade easily makes plant rows, trenches,

ditches to 8" deep. When hiller wings are

attached to furrower blade, attachment

makes hilled rows and raised bed

gardens. Convertsfrom a furrower to a

hiller and back again, in seconds, without

tools.

Row Marker Attachment

Do you like very straight, even,neat rows

in your garden? If so, the Row Marker is

a must attachment. Hooks quickly to the

HillerlFurrower attachment- eliminates

the needfor string, stakes, measuring

tape, etc. You'll like the straight rows it

helps you make if you lay out furrows, dig

compost trenches, or make raised beds.

The Row Marker extends from 28"-to-

49_", letting you vary the width between

rows to suit the crop you're planting.

Tire Chains

Chains provide extratraction when snow-

plowing, or underwet or slick conditions.

Tow Hitch Attachment

Converts your tiller to a tractor-type

hauling machine. Connects quickly to the

rear of the tiller Power Unit. This is a

standard-type tow hitch so it can tow

many kinds of equipment.

V-Sweep Cultivator

The V-SweepCultivator is a specialized

tool designed for between-row crop culti-

vation. Instead of stirring the soil, it

slices through just below the surface to

eliminate practically any weeds in its path.

The Sweepmounts easilyto the optional

Tow Hitch Attachment at the rear of the

PTOPower Unit. The blade is made of

high carbon, heat treated steeland

measures 2"wide (overall wing span is

20"),

The unique way the Sweepworks,

skimming along.just underneath the soil's

surface without turning the soil over,

makes this the idealtool for use in dry,

dusty conditions where it is important to

keep soil disturbance to a minimum.

And, becauseof its 20" wide cutting path,

it does an effective cultivation job at a fast

speed.

The Sweep's natural shallow cultivation

helps to prevent weed seedsfrom being

brought to the soil's surface. This

shallow cultivation feature also means

there's less chanceof damaging the roots

of your vegetables. For deeperor more

shallow cultivating, the bladedepth can

be changedwith asimple adjustment_

Wheel Weights

Help increasetraction by putting extra

weight directly on the wheels. They

reduce bucking and-jumping when deep-

tilling in heavysoil. They're shipped

empty- fill them with material like

concrete, sand, gravel,etc. They bolt

directly to the tiller wheels.

Wrap-Around Bumper Guard

Orderthis Bumper Guard by itself or

receiveit as one of the components if you

order the combination Dozer/Snow Blade

attachment. Protectsthe engine from

damage by wrapping around and protect-

ing many of the enginecomponents. 1"

diameter, high-strength steel tubing.
