Features and Controls

WARNING

Before operating your machine, care-

fully read and understand all safety,

controls and operating instructions in

this Manual, the separate Engine

Owner’s Manual, and on the decals on

the machine.

Failure to follow these instructions can

result in serious personal injury.

Figure 3-1: Controls located on handlebar.

The DISENGAGE position places the

INTRODUCTION

wheels in the freewheeling mode to allow

the unit to be moved without the engine

running. Use the DISENGAGE position

only when the engine is not running. See

“DANGER” statement that follows.

The two interconnected levers (B, Figure

3-1) control the engagement of forward

drive to the wheels and tines.

This Section describes the location and

function of the controls on your tiller.

Refer to the following section “Operation”

for detailed operating instructions.

To Operate the Forward Clutch Control:

Practice using these controls, with the

engine shut off, until you understand the

operation of the controls and feel confi-

dent with them.

1. Before engaging the Forward Clutch

Control, put the Wheel Gear Lever in the

ENGAGE position (see “WARNING”

below).

To shift to ENGAGE, gently (do not force)

move the lever forward while also rolling

the tiller a few inches forward or back-

ward. Moving the tiller helps to align the

shift mechanism with the transmission

wheel drive gears.

IMPORTANT: Refer to the separate engine

manufacturer’s Engine Owner’s Manual

for information about the controls on the

engine.

2. Pull up and hold one or both of the

levers against the handlebar grips to

engage the wheels and tines.

To shift to DISENGAGE (freewheel),

move the lever rearward, without rolling

the tiller. The wheels will roll freely

when the lever is properly set in the

DISENGAGE position.

3. Release BOTH levers to disengage

(stop) the wheels and tines. All forward

motion will stop (the engine will continue

to run).

WHEEL GEAR LEVER

This lever (A, Figure 3-1) has two posi-

tions: ENGAGE and DISENGAGE.

In the ENGAGE position, the wheels will

start turning when either the Forward

Clutch Control or the Reverse Clutch

Control is engaged (the tines will also

start turning when either clutch is

engaged).

WARNING

DANGER

Never place the Wheel Gear Lever in

DISENGAGE (Freewheel) when the

engine is running.

Never engage the wheels and tines with

the Forward Clutch Control or the

Reverse Clutch Control unless the

Wheel Gear Lever is in ENGAGE.

Having the Wheel Gear Lever in

DISENGAGE and then engaging the

tines/wheels with either the Forward

Clutch Control or the Reverse Clutch

Control could allow the tines to propel

the tiller rapidly forward or backward.

Engaging the Forward Clutch Control or

the Reverse Clutch Control when the

wheels are not engaged could allow the

tines to rapidly propel the tiller forward

or backward.

Failure to follow this warning could

or pulling the machine towards you.

Look behind to avoid obstacles.

• Never attempt to till in reverse.

Moving the lever up increases the tilling

depth. The lowest notch allows a tilling

depth of approximately six to eight

inches, depending on soil conditions.

IMPORTANT: The control for stopping

the recoil start engine is located on the

engine.

Failure to follow this warning could

result in personal injury or property

damage.

ENGINE THROTTLE CONTROL LEVER

The Engine Throttle Control Lever (located

on engine--see Figure 4-1) is used to reg-

ulate the engine speed. On the recoil start

model only, it is also used to stop the

engine (on the electric start model, the

electric start keyswitch is used to stop the

engine). The throttle settings are shown

below.

For best results, always begin tilling at

a very shallow depth setting and gradu-

ally increase the tilling depth. Complete

details on using the Depth Regulator are

found in the “Operation” Section of this

manual.

To Operate the Reverse Clutch Control:

1. Put the Wheel Gear Lever in the

ENGAGE position (see the “WARNING”

statement on previous page).

2. Stop all tiller motion by releasing the

Forward Clutch Control levers.

HANDLEBAR HEIGHT ADJUSTMENT

The handlebar height is adjustable to four

different settings. Set the handlebar

height to a comfortable setting, but keep

in mind that the handlebars will be lower

when the tines are engaged in the soil.

3. Lift up the handlebars until the tines

clear the ground, look behind you to avoid

any obstacles, and then pull the Reverse

Clutch Control knob out. The tines and

wheels will rotate in a reverse direction.

IMPORTANT: See “Starting and Stopping

the Engine” in the “Operation” Section for

detailed engine starting and stopping

instructions.

FAST - Use for most tilling and

cultivating projects.

4. Release the Reverse Clutch Control

knob to disengage (stop) the wheels and

tines. All reverse motion will stop (the

engine will continue to run).

To Adjust the Handlebar Height:

SLOW - Use when idling engine or

when slower tilling and cultivating

speeds are needed.

WARNING

• Do not attempt to till too deeply too

quickly. Gradually work down to

deeper tilling depths.

STOP - Stops the engine (on

recoil start models only).

STOP

ELECTRIC START KEYSWITCH

(MODEL E666M)

The ignition keyswitch on the electric start

model is used to start and stop the

engine. The keyswitch settings are

described below.

• Place the Depth Regulator Lever in the

“travel” position before starting the

engine. This position prevents the

tines from touching the ground until

you are ready to begin tilling.

Figure 3-3: Handlebar height adjustment.

1. Stop the engine, wait for all parts to

stop moving and then disconnect the

spark plug wire. Remove the ignition key

on electric start models.

Failure to follow this warning could

result in personal injury or property

damage.

Section 4: Operation 13

WARNING

Before tilling, contact your telephone or

utilities company and inquire if

underground equipment or lines are

used in your area. Their representative

will be glad to answer your questions

and tell you if any of their equipment or

lines are buried underground on your

property.

Figure 4-2: Use one hand to guide tiller

when moving forward.

Turning the Tiller Around

Figure 4-3: Raise tines off ground and look

behind when moving in reverse.

(b) As the tiller moves forward, relax

and let the wheels pull the unit along

while the tines dig. Walk behind and

a little to one side of the tiller. Use a

light but secure grip with one hand

on the handlebars, but keep your

arm loose. See Figure 4-2. Let the

tiller move ahead at its own pace

and do not push down on the han-

dlebars to try and force the tiller to

dig deeper – this takes weight off the

wheels, reduces traction, and causes

the tines to try and propel the tiller.

6. To Turn the Tiller Around:

(a) Practice turning the tiller in a level,

open area. Be very careful to keep

your feet and legs away from the

tines.

(b) To make a turn, reduce the engine

speed and then lift the handlebars

until the engine and tines are bal-

anced over the wheels (Figure 4-4).

ways on the handlebar to move the

tiller in the direction of the turn

WARNING

(Figure 4-5). After completing the

turn, slowly lower the tines into the

soil and increase the engine speed.

Figure 4-4: To begin turn, reduce engine

speed and lift handlebars until engine

and tines are balanced over wheels.

Do not push down on the

handlebars to try to make the tiller till

more deeply. This prevents the wheels

from holding the tiller back and can

allow the tines to rapidly propel the

tiller forward, which could result in loss

of control, property damage, or personal

injury.

Stopping the Tiller and Engine

1. To stop the wheels and tines, release

the Forward Clutch Control levers or the

Reverse Clutch Control knob (whichever

is engaged).

2. To stop the recoil start engine, move

the Engine Throttle Control Lever to

“STOP”. On electric start models, turn the

ignition keyswitch to “OFF” to stop the

engine.

5. For reverse motion of the wheels and

tines:

(a) Look behind and exercise caution

when operating in reverse. Do not

till while in reverse.

(b) Stop all forward motion before

reversing. Lift the handlebars with

one hand until the tines are off the

ground and then pull the Reverse

Clutch Control knob out to engage

reverse motion (see Figure 4-3). To

stop reverse motion, let go of the

Reverse Clutch Control knob.

Section 4: Operation

Tilling Tips & Techniques

• If the garden size will not permit

Let the tiller do the work

Avoid tilling soggy, wet soil

lengthwise and then crosswise tilling,

then overlap the first passes by one-

half a tiller width, followed by succes-

sive passes at one-quarter width (see

Figure 4-8).

• 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 foot-

prints in the freshly tilled soil) and

lightly, but securely grip the handlebar

with just one hand.

Tilling wet soil often results in large,

hard clumps of soil that can interfere

with planting. If time permits, wait a day

or two after heavy rains to allow the soil

to dry before tilling. Test soil by squeez-

ing it into a ball. If it compresses too

easily, it is too wet to till.

• With planning, you can allow enough

room between rows to cultivate (see

Figure 4-9). Leave room for the hood

width, plus enough extra room for

future plant growth.

• 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

causing the tiller to skip rapidly across

the ground. (Sometimes, slight down-

ward 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

at all.)

Avoid making footprints

When possible, walk on the untilled side

of the unit to avoid making footprints in

the freshly tilled soil. Footprints cause

soil compaction that can hamper root

penetration and contribute to soil

erosion. They can also “plant” unwanted

weed seeds back into the freshly tilled

ground.

Choosing correct wheel

and tine speeds

Figure 4-6

With experience, you will find the “just

right” tilling depth and tilling speed com-

bination that is best for your garden.

Tilling depths

• Avoid trying to dig too deeply too

quickly, especially when busting sod or

when tilling soil that hasn’t been tilled

for some time. Use shallow depth reg-

ulator settings (only an inch or two

deep) for the first passes through the

garden area. With each succeeding

pass, adjust the depth regulator to dig

another inch or two deeper. (Watering

the garden area a few 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, deep

tilling pass.)

Set the Engine Throttle Control Lever to

a speed to give the engine adequate

power and yet allow it to operate at the

slowest possible speed...at least until

you have achieved the maximum tilling

depth you desire. Faster engine speeds

may be desirable when making final

passes through the seedbed or when

cultivating. Selection of the correct

engine speed, in relation to the tilling

depth, will ensure a sufficient power

level to do the job without causing the

engine to labor.

Figure 4-7

• When cultivating (breaking up the

surface soil around plants to help

Suggested tilling patterns

destroy weeds), use very shallow depth

settings to prevent injury to plants whose

roots often grow close to the surface. If

needed, lift up on the handlebars slightly

to prevent the tines from digging too

deeply. (Cultivating on a regular basis

not only eliminates weeds, it also loosens

and aerates the soil for better moisture

absorption and faster plant growth.)

• 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 (see Figure 4-6).

When finished in one direction, make a

second pass at a right angle as shown

in Figure 4-7. Overlap each pass for

best results (in very hard ground it may

take three or four passes to thoroughly

pulverize the soil).

Section 4: Operation 15

Tilling Tips & Techniques

• Terraces should be only 2-to-3 feet

wide. Digging too far into the side of

the slope will expose poor subsoil that

is unproductive for plants.

Clearing the tines

Tilling on slopes

If you must garden on a moderate

slope, please follow two very important

guidelines:

The tines have a self-clearing action

which eliminates most tangling of debris

in the tines. However, occasionally dry

grass, stringy stalks or tough vines may

become tangled. Follow these proce-

dures to help avoid tangling and to clean

the tines, if necessary.

• To create a terrace, start at the top of

the slope and work down. Go back and

forth across the first row as shown in

Figure 4-10.

1. Till only on moderate slopes, never on

steep ground where footing is difficult

(review safety rules in the “Safety”

Section of this Manual).

• Each succeeding lower terrace is

started by walking below the terrace

you’re preparing. For added stability of

the tiller, always keep the uphill wheel

in the soft, newly tilled soil. Do not till

the last 12" or more of the downhill

outside edge of each terrace. This

untilled strip helps prevents the ter-

races from breaking apart and washing

downhill. It also provides a walking

path between rows.

• To reduce tangling, set the depth regu-

lator deep enough 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.

2. We recommend tilling up and down

slopes rather than terracing. Tilling

vertically on a slope allows maximum

planting area and also leaves room for

cultivating.

IMPORTANT: When tilling on slopes, be

sure the correct oil level is maintained in

the engine (check every one-half hour of

operation). The incline of the slope will

cause the oil to slant away from its

normal level and this can starve engine

parts of required lubrication. Keep the

engine oil level at the full point at all

times!

• While power composting, try swaying

the handlebars from side to side (about

6" to 12"). This “fishtailing” action

often clears the tines of debris.

• If tangling occurs, lift the tines out of

the soil and run the tiller in reverse for

a few feet. This reversing action

UPHILL

should unwind a good deal of debris.

A. Tilling up and down slopes:

• If reversing the tiller doesn’t clear the

debris, it may be necessary to remove

the debris by hand (a pocket knife will

help you to cut away the material).

• To keep soil erosion to a minimum, be

sure to add enough organic matter to

the soil so that it has good moisture-

holding texture and try to avoid leaving

footprints or wheel marks.

12" UNTILLED

REPEAT

DOWNHILL

• When tilling vertically, try to make the

first pass uphill as the tiller digs more

deeply going uphill than it does down-

hill. In soft soil or weeds, you may

have to lift the handlebars slightly while

going uphill. When going downhill,

overlap the first pass by about one-half

the width of the tiller.

Figure 4-10

WARNING

Before clearing the tines by hand, stop

the engine, allow all moving parts to

stop and disconnect the spark plug

wire. Remove the ignition key on elec-

tric start models.

C. Tilling across slopes without

using terraces:

• If vertical or terracing gardening aren’t

practical for you, then you can till later-

ally across a slope. We don’t really

recommend this method as it can

create unsure footing and invites soil

erosion.

Failure to follow this warning could

result in personal injury.

B. Terrace Gardening:

• When a slope is too steep or too short

for vertical tilling, it may be necessary

to till across the slope and create ter-

raced rows. Terraces are rows that are

cut into the side of a slope, creating a

narrow, but flat area on which to plant.

• As in terrace gardening, start at the top

of the slope and overlap the first pass

by half the width of the tiller. For added

stability of the tiller, always keep the

uphill wheel in the soft, newly tilled soil.

• On a long slope, you can make several

terraces, one below the other.

Section 4: Operation

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 and add even

more important nutrients to the soil.

• Ramps must be strong enough to

support the combined weight of the tiller

and any handlers. The ramps should

provide good traction to prevent slip-

ping; they should have side rails to

guide the tiller along the ramps; and

they should have a locking device to

secure them to the vehicle.

POWER COMPOSTING

Power composting simply means tilling

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 season and add important

natural nutrients to the soil.

After power composting, you may want to

plant a “green manure” cover crop to

protect the soil during the off-season. You • The handlers should wear sturdy

simply grow a crop of clover, alfalfa,

buckwheat, peas, beans, rye grass, grain,

or kale and then till it into the soil prior to

the planting season.

footwear that will help to prevent

slipping.

WARNING

When power composting, do not keep

the Depth Regulator Lever at a deep

setting if the tiller jumps or bucks.

• Position the loading vehicle so that the

ramp angle is as flat as possible (the

less incline to the ramp, the better).

Turn the vehicle’s engine off and apply

its parking brake.

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.

LOADING AND UNLOADING

THE TILLER

• When going up ramps, stand in the

normal operating position and push the

tiller ahead of you. Have a person at

each side to turn the wheels.

WARNING

Loading and unloading the tiller into a

vehicle is potentially hazardous and we

don’t recommend doing so unless abso-

lutely necessary, as this could result in

personal injury or property damage.

Failure to follow this warning could

result in personal injury.

• When going down ramps, walk back-

ward with the tiller following you. Keep

alert for any obstacles behind you.

Position a person at each wheel to

control the speed of the tiller. Never go

down ramps tiller-first, as the tiller could

tip forward.

The first place to begin is with crop

residues such as leftover vines, stalks,

stems and roots. Power compost these

crop residues as soon as they finish

bearing. The sooner this is done, the

better, as tender green matter is easier to

till under. Use the deepest depth regula-

tor setting possible without causing the

engine to labor or the tiller to jump ahead.

However, if you must load or unload the

tiller, follow the guidelines given next.

• Before loading or unloading, stop the

engine, wait for all parts to stop moving,

disconnect the spark plug wire and let

the engine and muffler cool. Remove

the ignition key on electric start models.

• Use wooden blocks to place on the

downhill side of the wheels if you need

to stop the tiller from rolling down the

ramp. Also, use the blocks to temporar-

ily keep the tiller in place on the ramps

(if necessary), and to chock the wheels

in place after the tiller is in the vehicle.

Standing cornstalks of reasonable height

can be power composted. Pushing over

(but not uprooting) cornstalks will often

make it easier for your tiller to chop up

the stalks. Keep the tines clear of exces-

sive tangling by “fishtailing” or frequently

using reverse. Make several passes, then

return a few days later to finish off any

remaining stubble.

• The tiller is too heavy (over 170 lbs.,

depending on model) and bulky to lift

safely by one person. Two or more

people should share the load.

• When the tiller is in the vehicle, prevent

it from rolling by engaging the wheels in

the wheel drive position (put Wheel Gear

Lever in ENGAGE). Chock the wheels

with blocks and securely tie the tiller

down.

• Use sturdy ramps and manually (engine

shut off) roll the tiller into and out of the

vehicle. Two or more people are needed

to do this.

remove the drain plug. The oil will start

flowing out of the drain hole (it may flow

slowly, especially in cold temperatures).

Check the transmission gear oil level after

every 30 hours of operation or whenever

you notice any oil leak. Operating the

tiller when the transmission is low on oil

can result in severe damage.

Before each use, check your tiller for

signs of an oil leak – usually a dirty, oily

accumulation either on the unit or on the

floor where it has been parked.

CARBURETOR/GOVERNOR

CONTROL ADJUSTMENTS

AIR CLEANER SERVICE

The engine air cleaner filters dirt and dust

out of the air before it enters the carbure-

tor. Operating the engine with a dirty,

clogged air filter can cause poor perfor-

mance and damage to the engine. Never

operate the engine without the air cleaner

installed. Inspect and service the air

cleaner more often if operating in very

dusty or dirty conditions.

WARNING

Operators shall not tamper with the

engine governor settings on the

machine; the governor controls the

maximum safe operating speed to

protect the engine and all moving parts

from damage caused by overspeed.

Authorized service shall be sought if a

problem exists.

Figure 5-3: Remove drain plug to drain

transmission gear oil (also remove oil fill

plug and oil level check plug).

ENGINE OIL SERVICE

Service the air cleaner as instructed in the

separate Engine Owner’s Manual.

Check the engine oil level before starting

the engine each day and check it after

each 5 hours of continuous operation.

Running the engine when it is low on oil

will quickly ruin the engine.

The carburetor was adjusted at the

factory for best operating speed. Refer to

the separate Engine Owner’s Manual for

any adjustment information or see your

authorized engine service dealer.

SPARK PLUG SERVICE

Inspect and clean or replace the spark

plug after every 100 operating hours or

annually. Clean the plug and set the gap

as described in the separate Engine

Owner’s Manual.

It is recommended that you change the

motor oil after every 10 hours of opera-

tion and even sooner when operating in

extremely dirty or dusty conditions. Refer

to the separate Engine Owner’s Manual

for detailed service instructions.

The governor controls the maximum safe

operating speed and protects the engine

and all moving parts from damage caused

by overspeeding. Do not tamper with the

engine governor settings. Seek autho-

rized service if a problem exists.

In some areas, local law requires using

resistor spark plugs to suppress ignition

signals. If the engine was originally

equipped with a resistor spark plug, use

the same type for replacement.

A. To Check the Engine Oil Level:

1. Move the tiller to a level area and shut

off the engine.

wheels roll freely when the Wheel Gear

Lever is in ENGAGE, the wheel gear cable

needs to be adjusted as described below.

2. Do routine tiller lubrication and check

for loose parts and hardware.

3. Protect the engine and perform recom-

mended engine maintenance by following

the engine storage instructions found in

the separate Engine Owner’s Manual.

NOTE: Be sure to protect the fuel lines,

carburetor and fuel tank from gum

deposits by removing fuel or by treating

fuel with a fuel stabilizer (follow engine

manufacturer’s recommendations).

1. With the engine shut off and the spark

plug wire disconnected, put the Wheel

Gear Lever in ENGAGE.

Replace

Figure 5-5: Checking tines for wear.

2. Loosen the top adjustment nut (A,

Figure 5-4) on the wheel gear cable

bracket that is located on the left side rear

of the transmission.

B. Removing a Single Tine:

1. Remove the two screws and nuts that

attach a single tine to the tine holder

(Figure 5-6). If needed, use penetrating

oil to help free the nuts.

3. Push the wheel gear cable (B) down

and roll the tiller slightly forward or back-

ward until the eccentric lever (C) engages

(locks) the wheels. Hold the cable in that

position and tighten the top (A) and

bottom (D) adjustment nuts.

4. On electric start units, follow “Battery

Storage” instructions in this Section.

2. When installing a single tine, be sure

to position it so that its cutting edge will

enter the soil first as the tiller moves

forward.

5. Store unit in a clean, dry area.

6. Never store the tiller with fuel in the

fuel tank in an enclosed area where gas

fumes could reach an open flame or

spark, or where ignition sources are

present (space heaters, hot water heaters,

furnaces, etc.).

C. Removing a Tine Assembly:

4. Move the Wheel Gear Lever to

ENGAGE and DISENGAGE several times

to check the adjustment. The wheels

should not roll when the lever is in

ENGAGE, but they should roll when the

lever is in DISENGAGE. Readjust the

cable as required.

1. If removing both tine assemblies, mark

them “left” and “right” before removal.

Doing so will help ensure that the assem-

blies are reinstalled on the correct sides

of the tiller.

BOLO TINES

2. Remove the screw and locknut that

secure the tine assembly to the tine shaft

(Photo 5-7). Pull the tine assembly off

the shaft (if necessary, use a rubber

mallet to tap the tine assembly outward).

The tines will wear with use and should

be inspected at the beginning of each

tilling season and after every 30 operating

hours. Tines can be replaced individually

or as a complete set. Never inspect or

service the tines unless the engine is

stopped, the spark plug wire is discon-

nected, and the ignition key is removed

on electric start models.

3. Before reinstalling the tine assembly,

inspect the tine shaft for rust, rough

spots or burrs and file or sand as needed.

Apply a thin coat of grease to the shaft.

4. Install each tine assembly so that the

cutting edge of the tines will enter the

soil first when the tiller moves forward.

Secure the tine assembly to the tine shaft

using the screw and locknut previously

removed. Tighten securely.

A. Tine Inspection:

With use, the tines will become shorter,

narrower and pointed (Figure 5-5). Badly

worn tines will result in a loss of tilling

depth and reduced effectiveness when

chopping up and turning under organic

matter. Use Figure 5-5 as a guide to

when the tines should be replaced.

CHECKING AND ADJUSTING

TENSION ON CLUTCH BELTS

A loose belt will also result in premature

belt wear.

Maintaining correct belt tension is impor-

tant to good tilling performance and long

belt life. A loose belt will slip on the

engine and transmission pulleys and

cause the tines and wheels to slow down

– or stop – even though the engine is

running at full speed. A loose belt will

also result in premature belt wear.

• Check belt tension after the first two

hours of break-in operation and after

every 10 operating hours.

• At the end of each tilling season, check

the belt for cracks, cuts or frayed edges.

A belt in poor condition should be

replaced.

Checking and Adjusting

Forward Clutch Belt Tension

It is important to maintain correct tension

on the forward clutch belt. A loose belt

will cause the tines and wheels to slow

down – or stop completely – even though

the engine is running at full speed.

While checking belt tension, also check

for cracks, cuts or frayed edges. A belt in
