Savethe hardware.

STEP 1: Activating and
Charging the Battery

Battery producesexplosive gases.

IMPORTANT: The battery is shipped dry.
It needs battery electrolytic fluid (batterygrade 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
activated and charged, you should review
these instructions with your battery
technician.
IMPORTANT: It is strongly recommended that you have the battery
activated and charged by a trained professional (Troy-Bilt Dealer, service station,
farm equipment dealer, etc.), if you are
not experienced with these procedures.

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
workingon or near the battery.

• Keep away sparks, flames,
cigarettes.

4. Removethe six filler caps (D, Figure
2-17) on top of the battery.
IMPORTANT: Be sure to wearing protective clothes, rubber gloves, and eye
protection.

Remove metal jewelry before working
near the battery or near the electrical
system. Failure to comply may cause 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 face them in the
opposite direction from which they were
shipped.

5. Fill each cell to the Upper Level line
printed on the battery case (E, Figure217) using battery-grade electrolytic
solution. (This is 1.265 specific gravity
sulfuric acid.) Temperature of battery and
electrolytic fluid is ideal when between
60°F and 80°F. Do not add water or any
other liquid to the battery during this
initial activation.

the cells during charging=

Section2: Assembly
TOCHARGETHE BATTERY:
1. Use one of the three charging methods
described below for maximum starting
capacity and longest battery life.
NOTE:Bubbling (gassing freely) electrolyte solution within the battery cells
indicates that the battery is charged.
These bubbles emit toxic gases that
escape from the cells when you remove
the cell caps. Always wear safety goggles
to protect your eyes when checking for
bubbles. A flashlight makes the inspection 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 charging or 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
coulddamage the battery.

• First Alternative Charging Method:
Chargethe battery at a rate of 440-6
amperes until all cells bubble freely. Do
not exceed 8 hours chargetime.
• SecondAlternative Charging Method:
Chargethe battery at a rate of
6-to-12 amperes until all cells bubble
freely. Do not exceed 4 hours charge
time.
2. Turn offthe charging equipment and
disconnect the charger cables from the
battery terminals.
3. Recheck electrolyte level in each cell.
Top off any low cells with electrolyte
solution up to the "Upper" level line.
4. Securely replace 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
• Our Recommended Method:
Chargethe battery at a rate of 14o-2
amperes until all cells bubble freely. Do
not exceed 24 hours charge time.

1. Carefully place the activated battery
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
behind the 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 could cause
a short circuit leading to electrical
burnsor explosionof batterygases.
• Never bring a gas can near the positive
(+) battery terminal. A short circuit
could occur leading to an explosion of
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. Use two
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 screws are overtightened.)

Improper battery venting can cause a
battery to explode resulting in severe
personal injury. Be sure the vent tube is
not crimped, pinched,folded, or blocked
in any way.

3. To install the vent tube (E, Figure 218), 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

turn. If practicing, leavein DISENGAGE.

• Always return to NEUTRALand let all
motion stop before shifting to
FORWARDor REVERSE.

IMPORTANT: Do not move Tines/PTO

Wheels/Tines/PTO Drive Lever is in
NEUTRAL.Tiller damagemay occur!

The following pagesprovide guidelines
for using your tiller effectively and safely
in various gardening applications. Be
sure to read Tilling Tips & Techniques,in
this Section, before you actually put the
tines into the soil.

5. To move the 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=

This is a traditionalstandard-rotating-0ne
(SRT) tiller with forward rotating tines. It
operates in a completely different manner
than counter-rotating-0ne (CRT)tillers, or
from front-tine tillers.

Section 4: Operation
Making Turns
Turning the tiller is easy andjust requires
practice. First find the balancepoint
betweenthe engine and the tines by lifting
up the handlebars (Figure4-5). Onceyou
find the balancepoint, then let the
powered wheels do the turning as you
push sideways on the handlebars in the
direction of the turn. Practice the turning
maneuver described here in a large open
area. Once comfortable turning the tiller,
you can then take it to the garden area.

Figure 4-3: Moving tiller forward:
squeeze one Forward Interlock Lever
and then move WheelslTineslPTO
Drive Lever down to FORWARD.

I. At the end of a row, move the Wheels/
Figure 4.4: Guide tiller with one hand.

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). Use a
firm grip on the handlebars but keepyour
arm relaxed.
IMPORTANT: Let the tiller move ahead at
its own pace. Do not push it ahead--this
reduces operator control and tilling efficiency. 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
Damage to 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 with backingthe tiller.

while

1. Shift the TineslWheels/PTODrive Lever
(Figure 4-2) into NEUTRALand move the
Wheel Speed Lever to the SLOW position.
2. Move Tines/PTOClutch Lever (Figure
4-2) into DISENGAGEposition.
3. Verify that the area behind you is clear.
4. Lift up the handlebarsuntil the tines
are off the ground, then shift the
Wheels/TineslPTODrive Lever all the way
up and hold. You do not need to squeeze
the Forward Interlock Levers to use
reverse.

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
away from the tines (which should be disengaged). Let the powered wheels do the
hard work. The inside wheel will pivot in
placewhile the outside wheel drives the
tiller around in the direction of the turn.

5. The unit immediately engages 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 Levers will not stop REVERSE
motion.)

Figure 4.5:

NOTE: Use REVERSEif necessaryto turn
in a limited space.

To Stop the Engine
Move the engine Throttle Lever to the
STOPposition. Then, on electric start
models, turn key to OFF. Remove the key
for safekeeping.

TransportingThe Tiller Around
YourProperty
When the engine is running, the tiller's
powered wheels make moving the tiller to
and from the garden easy. If the engine is
not running set the Wheel Speed Lever to
FREEWHEELposition to roll the tiller to
another location.

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 Department 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
To help avoid personal injury from
revolving tines, always put the The Forward Interlock System has an

function. Checkthe system for proper
operation each time prior to using the
tiller or PTOpower unit.
1. Placethe Tines/PTOClutch Lever in
DISENGAGEposition.
2. Move Depth RegulatorLeverdown all the
way into the Travel setting.

4. Start engine as described under
Starting and Stopping the Engine,in this
section. Set engine throttle lever to
SLOW, and let engine warm up.
5. Squeezeand holdjust one of the
Forward Interlock Levers against the
handlebar grip while moving the Wheels/
Tines/PTO Drive Lever down to
FORWARD(Figure 4-3). As the tiller
moves forward, releasethe Forward Interlock Lever briefly. The engine should
start to stall out if the interlock system is
working properly. If it does start to stall,
quickly squeezethe lever up against the
handlebar grip, 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 Forward Interlock Lever is released.
6. If the engine does not begin to shut off
when either Forward Interlock lever is
released, shut the engine off, remove the
key (if electric start), and do not operate
the tiller or PTOpower unit until the
system has been repaired and is functioning properly.

3. If using engine power, move Wheel
Speed Lever to either SLOWor FAST,and
use the Wheels/Tines/PTODrive Leverto
drive the wheels.

IMPORTANT: To avoid possible damage
to the Forward Interlock Safety system,
do not use high-pressure sprays near the
wire harness receptacleor neutral plunger
assembly.

4. If the engine is stopped, move Wheel
Speed Lever to FREEWHEEL,and
manually push tiller.

Loading and Unloading the 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 against the handlebars
enablesthe ignition system; therefore,
you must squeezeat least one lever
whenever the Wheels/Tines/PTODrive
Lever is engaged in FORWARD.
IMPORTANT: The interlock system also
prevents the engine from starting if the
Wheels/Tines/PTODrive Lever is engaged
in FORWARD.
2O

Figure 4.6: Plug and receptacle of
Forward Interlock Safety System
must be securely connected.

To test the Forward Interlock System:
1. Move tiller outside to level ground.
Removeany obstacles.
2. Checkthat the Forward Interlock wire
harness plug, at the bottom of the handlebars (Figure4-6), is securely connected
to the receptacleon the top, right side of
the transmission.
3. Move Wheel Speed Lever (Figure 4-2)
to SLOW position and move Tines/PTO
Clutch Lever to DISENGAGE.

The following provides information on
tiller loading,unloading, and requirements
before loading and unloading the tiller,
Readthe following instructionscarefully
before attempting to load or unload your
tiller.
Before Loading or Unloading the
Tiller
• Ramps must be strong enough to
support the combined weight of the tiller
and handlers. They should provide good
traction to prevent slipping; 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.
• Handlers should wear sturdy footwear
that will help to prevent slipping.

Section 4: Operation
• Turn the vehicle's engine off and apply
its parking brake.

2. Move the Tines/PTOClutch Lever
(Figure 4-2) to DISENGAGEposition.

• Position the loading vehicle so that the
ramp angle is as flat as possible (the
less incline to the ramp, the better).

3. Set the Depth Regulator Lever (Figure
4-2) to the Travel position.

Loading the Tiller
I. Use loading ramps that are strong and
wide enough to safely hold the weight of
the tiller and the operator combined-your tiller weighs between 280 and 325
Ibs.
2. Move the Tines/PTO Clutch Lever
(Figure 4-2) into DISENGAGEposition.
3. Set the Depth Regulator lever (Figure
4-2) to the Travel position.
4. Move Wheel Speed Lever (Figure4-2)
into SLOWposition and reduce the
engine throttle speed.

4. Move Wheel Speed Lever (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 behind you.
5. Move and hold the Wheels/Tines/PTO
Lever into REVERSEdrive and back down
the ramps (Figure 4-8). Checkthe wheels
as you move the tiller backward. Ensure
that they move down the center of each
ramp.

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. Prevent tiller from rolling in vehicle.
LeaveWheel Speed Lever in FASTor
SLOW position, chock wheels with blocks
and tie down the tiller.

Unloading the Tiller
IMPORTANT: Neverunload the tiller in
FORWARDdrive. The tiller could tip
forward and expose you 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 and the operator combined-your tiller weighs between 280 and 325
Ibs.

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 reverse speeds SLOW and FAST,
as set with the Wheel Speed Lever.
Table 4-I shows the range of wheel and
tine speeds availablewhen using the two
belt speed ranges and the FASTand
SLOWselections on the Wheel Speed
Lever.

Figure 4-8: To go down ramps, use
REVERSE drive.

Changing Speed Belts

Figure 4.7: To go up ramps, use
FORWARD drive.

This change is done quickly and without
tools (Figures 4-9 through 4-13).

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 one speed range into the other, in
combination with the FASTand SLOW
wheel speeds,you obtain a choice of four
different forward wheel speeds and 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.

Section 4: Operation
4. Go to right side of tiller and finish
seating the belt.
The HIGH speed belt range position
combined with a FAST wheel speed
setting propels the tiller at the fastest
pace. Reducethe engine throttle speed
when starting out to help avoid personal
injury or propertydamage if using this
speed combination.

5. Still holding the lever up in REVERSE
position, and workingfrom the left side of
the tiller, move the belt from the lowerfront transmission groove to the lowerrear transmission groove.
6. Go to the right side of the tiller and
finish seating the belt (Figure 4-I 3).

3. Kneel on 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 same time, use
your left hand to work the belt part-way
onto the lower-front transmission pulley
groove (Figure 4-10).

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).

Your tiller has four FORWARDwheel/tine
speed combinations for handling a variety
of tilling tasks and gardeningjobs. Experiment with the tine depth, engine speed,
and wheel/tine speed and determine the
combination that provides the best
results. Hereare some tips:

2. When tilling untilled or hard earth, do
not set the Depth Regulator too deep. The
tiller will buck and the engine will load
down.

IMPORTANT: Proper belt tension is
important for good performance. See
Section 5, Drive Belt Maintenance for
information on belt maintenance schedule

3. You will know your settings are ideal
when the tines break-up the soil easily,
the engine does not labor, and your
progress is steadyand smooth.

1. Advance the throttle lever so the engine
has sufficient power.

6. Finish seating the belt from the right
side of the tiller.

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.

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 handlebar with just
one hand (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
causing the 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. Use shallow depth settings
(only an inch or two deep) for the first
passesthrough 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.)
• When cultivating (breakingup the
surfacesoil around plants to help
destroy weeds), use very shallow depth
settingsto prevent injury to plants whose
roots often grow close to the surface. If
needed,lift up on the handlebarsslightly
to preventthe tines from digging too
deeply. Cultivatingon a regular basis not
only eliminatesweeds,it also loosensand
aeratesthe soil for batter moisture
absorption and fasterplant 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 a day or
two after heavy rains to allow the soil to
dry before tilling. Test the soil by
squeezing it into a ball. If it compresses
too easily, it is too wet to till.

• Coveringseedswith less need
to hold up the handlebars.
• Cultivating(tiller travelsfaster,
rides higheron the soil; allows
engineRPM to be reduced;
handlebarsdon't haveto be
raised).
• Keepinglarge areastilled and
cultivatedin the summer.
• Tilling organicmatter under.
• Moving tiller quickly.
• Cultivatingbetweenraised
bedsusing the optional
hillerlfurrower.

To help avoid personalinjury, be aware
that the tiller can unexpectedlybounce
up orjump ahead and propelaway from
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
maintain controlof the tiller:
• Walk behind and to the side of the
tiller. Use one handon the handlebars,
relaxing your arm but with a secure
handgrip.
• Use shallow depth regulator settings.
Till gradually deeper.
• Use slower wheel, tine and engine
speeds.
• Clear the tilling area of all large
stones, rootsand otherdebris.
• Do not put downwardpressureon the
handlebars. If needed, apply slight
upward handlebar pressureto keep the
tines from 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 you cannot
roachthe lever or have lost control, Let
Go OfThe Handlebarsand All Controls. 23

Section4: Operation

Tilling Tips & 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). Footprints cause soil compaction that can
hamper root penetrationand contribute
to soil erosion. They can also "plant"
unwantedweed seeds back into the
newly tilled soil.

IMPORTANT: When tilling on slopes,
be sure the correct oil level is maintained in the engine (check every onehalf 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.
Keepthe engine oil level at the full point
at all times!
A. Tilling up and down slopes:

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 414). When finished in one direction,
make a second pass at a right angle as
shown in Figure 4-15. Overlapeach
pass for best results (in very hard
ground it may take three or four
passesto thoroughly pulverize the
soil).
• If the garden size will not permit
lengthwise and then crosswise tilling,
then overlap the first passes by onehalf a tiller width, followed by successive 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 on slopes
If you must garden on sloping ground,
pleasefollow two very important guidelines:
I= Till only on moderate slopes, 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 area and also leaves room
for cultivating.

• To keepsoil erosion to a minimum, be
sure to add enough organic matter to
the soil so that it has good moistureholding texture and try to avoid leaving
footprints or wheel marks.

• When tilling vertically, try to make the
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 range and SLOW wheel speed lever
position. See Changing Speed Belts 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
good footing.
• Wear footwear that increases

Figure 4.14

stability and reducesslippage.
• Do not use FAST wheel speed
positionwhen on slopedground.

Figure 4.15

• 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 preventengine damage 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 maintained during all uphill/downhill
tilling operations. Check the level of
the oil in yourengine after every onehalf hourof operation.

Figure4-16

Section4: Operation

Tilling Tips & 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
become tangled.
Follow theseprocedures to help avoid
tanglingand to clear the tines, if
necessary.

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
could result in personal injury.

Figure 4.18

B. Terrace Gardening:
• Whena slope is too steep 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 area on whichto
plant.
• On a long slope, you can make several
terraces, one below the other.
• Terracesshould 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.
• 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 4-18,
• 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, newly tilled soil. Do not till
the last 12" or more of the downhill

C. Tilling across slopes
withoutterracing
• If vertical or terracinggardening aren't
practical for you, then you can till
laterally across a slope, We don't
really recommend this method as it
can create unsure footing and invites
soil erosion.
• Study the terrain to make certain the
slope is not too steep for safe tilling.
If possible, make terracedrows or till
vertically.
• Move the belt into LOW belt range and
the Wheel Speed Gear Lever 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.
Foradded stability, keep the uphill
wheel in the soft, newly tilled soil. Each
succeeding terraced area is started by
walking belowthe terrace you are
preparing (Figure 4-19).

• To reduce tangling, set the Depth
Regulator 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.
• While power composting, try swaying
the handlebarsfrom side to side (about
6" to 12"). This "fishtailing" action
often clears the tines of debris.
• It may be necessaryto remove the
debris by hand (a pocket knife will help
you to cut away the material).

outside edge of each terrace. This
untilled strip helps prevents the
terraces from breaking apart and
washing downhill. It also provides a
walking path between rows.
Figure 4.19: Make a terrace in just 4
or 5 passes with the tiller.

Section 4: Operation

Tilling Tips & Techniques
POWERCOMPOSTING
Power composting 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.

When power composting,do not keep
the Depth Regulator Lever at a deep
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
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 regulator
setting possible without causing the
engine to labor or the tiller to jump
ahead.
Standing cornstalks of reasonableheight
can be power composted (Figure 4-20).
Pushing over (but not uprooting) cornstalks will often make it easierfor your
tiller to chop up the stalks. Keepthe
tines clear of excessivetangling by "fishtailing" or frequently using reverse.
Make several passes, then return a few
days later to finish off any remaining
stubble.

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.
After power composting, you may want
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
between the left wheel and the transmission case (Figure4-19). Do not use the
right wheel becausedamage could occur
to the air cleaner, carburetor or throttle
linkage.

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-row planting technique is
spreading seeds anywhere from 10
inches to 2 feet wide or more. As a
result, you can grow anywhere from 3 to
4 times (or more) produce in the same
space that is normally set asidefor an
area that has narrow, single rows.
Wide-row planting automatically shades
the ground which keeps weed 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 prepare the seedbedand mark
off the rows with string, hand-broadcast
the seeds as if seeding a lawn (not quite
as much as lawn seed). Cover with soil
and tamp the area firmly with a hoe.
Tilling Under Corn
After corn is harvested, the stalks should
be tilled into the soil while still green.
Dry plants are more difficult to till under,
and the 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
chop, cut, and work under.

Figure 4.20: Tilling under corn
stalks.

2. Eachnew pass should overlap the
previous pass by one-half the width of
the tiller.
3. Till as deeply as possible. Pull the
Depth Regulator all the way UP and
engagethe lowest notch for deep tilling.
Use either LOW or HIGHbelt range and
SLOWwheel speedgear position.
Let the tilled-in stalks decompose for a
week or so. Then till in the remaining
residue as deep as possible.

4. Checkthe five bolts securing the tiller
housing cover to the left side of the transmission (B in Figure 5-3). Gear oil can
leakfrom a loose housing cover. To
reach the bolts, remove the left side tine
holder. See Bolo TineMaintenancein this
Section for tine holder removal directions.

Most hardware on your tiller is visible.
Pay particular attention to hardware

behind the bolt head is 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
plunger assembly(Figure5-2). If loose,
immobilize bolt head with one wrench and
use another wrench to tighten the nut.
3. Checkthe three rear bearing cap
screws under the depth regulator

Tiller Lubrication
Proper lubrication of the tiller's mechanical parts is an essential part of good
maintenance. Lubrication should be done
after every ten (10) hours of operation.
Use ordinary 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,
remove the build-up and re-apply oil or

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 between the 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 Speed Lever (B, Figure5-4).
3. Greasethe face of the belt adjustment
block (C, Figure 5-4).
4. Oil the Depth Regulator Lever,
including the spring in the mounting
bracket(D, Figure5-4).
5. Oil the full length of the throttle cable
casing (E, Figure 5-4).
6. Oil threads on HandlebarHeight Adjustment Lever (F, Figure 5-4).

7. Grease left- and right-side engine
mounting bars at the top, the middle, and
bottom (G, Figure 5-4).
8. Greasethe zerk grease 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 multipurpose grease at beginning and end of
tilling season.

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 transmission and the Line attachment transmissions have oil relief vents (Figure 5-6).

9. Keepthe PTOaccess area well-greased
(I, Figure 5-5). If the Tines/PTOClutch
Lever becomes hard to move, squirt some
oil into its access hole, and work it back
and forth to disperse the oil.

Oil Maintenance

The vents allow small amounts of oil to
seep out.

Checking for Oil Leaks
At 25-hour operation intervals, checkthe
tiller for oil leaks. Inspect for oil accumulations on the tiller or the floor where it's
stored.
A small amount of oil seepageor wetness
around a shaft opening or
cover is no cause for
alarm. But a heavy concentration of oil is more
serious. You should
tighten all bolts immediately, and replace any
worn seals or gaskets.

Figure 5.4: Tiller lubrication points
(wheel removed for clarity).

It may be impossible to
determine how much oil
has been lost, so check the
oil levels in the PTOtransmission and the tine
attachment before using
the tiller again. Add any
necessary gear oil.
Serious damage to the
transmission components
can result from operation
when gear oil levels are
low.

If a serious leak is discovered, please
contact your authorized dealer or the
Factory Technical Service Department for
service advice.
Checking Gear Oil Levels
Every 30 hours of operation, check the
gear oil level in both the power unit transmission and the tine attachment transmission. Operatingthem while low on gear
oil (even briefly) can cause serious
damageto internal components.
Preparation
I. The transmissionsmustbe cool,
since hot gear oil expands and gives a
false reading.
2. The power unit transmission and the
Lineattachment transmission must be
connected when checking (or adding)
gear oil.
Checkingthe Power Unit Oil Level
I. Move the tiller to level ground. Move
the Depth Regulator up so the tines rest
on the ground.

Failure to follow these instructionscan result in serious personalinjuryor propertydamage.
For Dipsticks With 'CheckCold"Marking
(Cold means 2 hours has passed since
the tiller was used.)
I. Move the tiller to level ground.
2. Pull the Depth Regulator Lever back,
then push it down all the way (to engage
its top notch).

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 seeps out, seeAdding or Changing
Gear Oil.
Checkingthe Tine
AttachmentOil Level
IMPORTANT: Two different gear oil
checking procedures for the tine attachment transmission are described next.
Use the first procedure if the dipstick in
your tine attachment has only a 'Check
Cold' marking. Use the second procedure
if the dipstick has both cold and hot
markings at the end. First remove the
dipstick from the tine attachment transmission (Figure 5-8) to see which type
dipstick you have. Then replace the
dipstick with markings on dipstick facing
to rear.

3. Place a sturdy support under the
engine to prevent the tiller from tilting too
far=
4. Now slide three pieces of 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 face to
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 reading will
result.
8. Remove dipstick and check oil level. It
should be anywhere within the crosshatched area or 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 ChangingGear Oil next.
For Dipsticks WithHot/ColdMarkings
1. Move the tiller to level ground.
2. Pull the Depth Regulator Lever back,
then push it down all the way (to engage
its top notch).
3. Place a sturdy support under the
engine to prevent the tiller from tilting too
far=

Figure 5-8: Checking gear oil level;
markings on dipstick (tine attach.
ment transmission) must face rear.

4. Cold reading (preferred method):
(Two hours has passed since the tiller
was used.) Place a 2" x 4" board (on
edge) under the drag bar- raising the tiller
and drag bar about 3-I12" aboveground.
Hot reading: (Tiller was operatedfor
more than 30 minutes within the past
hour.) Do not use the wood prop to
elevatethe tiller.
5. Follow Steps 4, 5 and 6 given for the
other dipstick type.
6. Removedipstick and check level. It
should be within or above the "Cold"
range marking 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 Gear Oil.
Adding or Changing Gear Oil
Forpartial fill-ups (just a few ounces or
less), use SAE 140, SAE 85W-140, or SAE
80W-90 weight gear oil with an API rating
ofGL-4or GL-5. Forfull replacement,
use SAE 140 or SAE85W-140 gear oil
with an API rating of GL-4 only. (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 transmission damage=
The gear oil does not need to be changed.
Do so only if you know, or suspect, it is
contaminated with dirt, sand or other
foreign particles.
Gearoil is available at authorized dealers
and most service stations, power
equipment centers, or farm/heavy
equipment outlets=
Capacities: Power unit transmission
holds approximately 60 ozs.; Tine Attachment transmission holds approximately
12-112"ozs.

Drive Belt Maintenance
Measuringand Adjusting
DriveBelt Tension
On a new tiller (or if a new belt is
installed), the belt tension will probably
need to be adjusted after thefirst two (2)
hours of operation. Thereafter, check belt
tension every ten (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 unable to 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.

3. The belt tension is correct if the front
of the clutch roller is 1/4"-to-5/16" away
from the face of the upright bracket that
holds theadjustment block in place
(Figure 5-12). To measure this distance:

4. If the belt tension is correct, move the
Wheels/Fines/PTODrive Lever back to
NEUTRAL.

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 edge of the tool
must be facing the roller.) Refer to
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 easily fits in, the belt is too
tight.

Tips on keeping the drive belt in top
condition include:

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.

• Always put the Wheels/Tines/PTODrive
Lever in NEUTRALwhen the tiller is not in
use,

How to Adjust Belt Tension

• Keep tensionadjusted correctly.
• Don't "speed shift" when moving the
Wheels/Tines/PTODrive Lever between
FORWARDand REVERSE.
How to Measure Belt Tension

Figure 5-11: Use this belt adjust*
ment tool to measure and adjust
drive belt 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.

1. Before taking a measurement, be sure
the linkages and pivot points on the
Wheels/Tines/PTODrive Lever are clean

and lubricated. If there is any binding,
you won't get true measurements. Also,
you'll need the belt adjustment tool you
receivedwith your new tiller (Figure
5-11).

In most cases, the clutch roller will not
have been very far out of position, so the
adjustment block will only need to be
moved slightly (up or down)=

2. Move the Wheels/Tines/PTODrive
Leverfully down to the FORWARD
position. The clutch roller at the bottom
of the lever should be positioned underneaththe 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.

approximately equals the distance the
roller moves.

2. Move the Wheels/Tines/PTODrive
Lever to NEUTRALposition. The clutch
roller will come to rest anywhere on the
face of the belt adjustment block,
depending upon drive belt length and
current belt tension adjustment.

NOTE: If the adjustment block is all the
way down and the measurement between
the clutch roller and the bracket is less
than 1/4",then a new drive belt is needed.

5. Use one 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

Reverse Disc Inspection
The reverse disc is made of steel with a
special, long-lasting rubber compound
bonded to the disc rim. Since this is a
wearingpart, it should be inspectedafter
every 30 operating hours.

Figure 5-19: Move top half of belt
over pulley and reverse disc.

Figure 5-21: Seat belt in upper
pulley, then in Iower pulley (High
Range position shown).

1. Measurethe widthof the outside edge
of the disc as shown in Figure 5-22.
Replace the disc before the rubber edge

Failure to do so could cause the steel
underneath the rubber to damagethe
transmission pulley.

7. Move the 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

adjust for correct belt tension as
explained previously.
Reverse Drive
System Maintenance
These instructions explain how to inspect,
replace or adjust thevarious reverse drive
components,
But first, here's how the reverse drive
system works: When you raise the
Wheels/Tines/PTODrive Lever up in
REVERSEposition, this lowers the rubberized reverse disc (it's attached to the
engine drive pulley) until this rotating disc
contacts thetransmission drive pulley=
The friction between the rotating reverse
disc and the 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
reverse direction.

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
_

Replacing the Reverse Disc
Followthese steps to replace the reverse
disc. (If your tiller has a Bumper Attachment mounted, it must be removed first.)
Removingthe ReverseDisc
1. Move Wheelsfrines/PTO Drive Lever in
NEUTRALposition.
2. Wedge a 5/16"-thick board between top
of engine pulley (avoidcontacting reverse
disc) and cast iron housing next to it.
This immobilizes pulley.
3. Use a 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. Back the
bolt out as far as possible. Then angle
the disc a little to remove it. Bring the
bolt and Iockwasher along with the disc.

and engine mount move down to press
on the reverse adjustment bolt (Figure 524). 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 prevent the reverse disc 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 reverse drive operating problems, as
explainednext.

ment bolt should be adjusted upward (see
instructions thatfollow). Moving adjustment bolt upward will also solve problem
of a tiller that goes into REVERSEon its
own.

Figure 5.25: Checking Reverse
Disc in NEUTRAL.

3. Use your 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 pressure to hold lever
up in REVERSE,then reverse adjustment
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 (counterclockwise) until it touchesthe bolt head.

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 would disengagethe bolt
from the locking groove in the side of the
plunger).

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.

Figure 5-28: Loosen jam nut before
turning reverse adjustment bolt.

Figure 5.27: Hold bolt steady while
loosening or tightening jam nut.

8. Hold the plunger retaining bolt steady
with a wrenchwhiletightening thejam
nut against the side of the plunger housing
(Figure5-27),

3. Turn the bolt in until it tightens against
the plunger inside the spring, The bolt
must be tight to prevent plunger from
turning - but be careful not to overtighten
and break the bolt.
4. Placea 7/8" wrench on the head of the
reverse adjustment bolt and a 9/16"
wrench on thejam nut below it (Figure 528), 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 reverse adjustment bolt, and
the reverse disc should be at least 3/16"
away from the transmission drive pulley.
If the reverse disc is any closer than this,
raise the reverse adjustment bolt (turn it
counterclockwise).
6. Check that reverse disc is at least 3/16"
away from transmission drive pulley,
Then hold reverse adjustment bolt steady
with one wrench while tighteningjam nut
with a second wrench (Figure 5-28).

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 maintenance recommendation, as debris can
cause premature wear to the Oneshaft
and its oil seals. Refer to 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 pressure for
tilling is 104o-20 psi (pounds per square
inch). Both tires should be inflated
equally. (Unequal pressure can cause the
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 remove a wheel.

It is recommended that you changethe oil
every ten (I0) operating hours and even
sooner when operating in extremely dirty
or dusty conditions. Refer to the separate
Engine Owner'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 engine air cleaner filters dirt and dust
out of the air before it enters the carburetor. Operating the engine with a dirty,
clogged air filter can cause poor performance and damage to the engine. Never
operate the engine without the air cleaner
installed. Inspect and 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.

1. Prop the transmission up with a sturdy
block to raise the wheel you want to
remove off the ground.

Refer to the engine manufacturer's literature supplied with your tiller for complete
air cleaner service and maintenance information.

2. Move the Wheel Speed Lever to either
SLOWor FASTposition to prevent the
wheels from turning.

Throttle Cable Maintenance

3. Use a 5/16" 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 eyes from the possibilityof
flying metal particles.

The throttle lever settings are factoryadjusted, so unnecessary adjustments
should not bemade. However, if the
engine does 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
Engine Oil Maintenance
Checkthe engine oil level before starting
the engine each day and after each 5
hours of continuous operation. Running
the engine when it is low on oil will
quickly ruin the engine.

Your engine is equipped with 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 engine operation. Remove and
inspect the plug every 50 operating hours
or annually, whichever occurs first.
The correct electrode gap is .030". Check
the gap with a feeler gauge. 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. Every month 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

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

5. Charge battery (with caps removed)
until all cells are gassing freely. (To
check for gassing, wear protective
goggles and inspect each cell with flashlight for bubbling of electrolyte solution.)
Use one of the following methods to
charge battery:
a.

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 away during the off-season, we
recommend the battery be fully charged.
At the end of the storage period, the
battery should be recharged again=

RecommendedMethod: charge the
battery at a rate of 1-to-2 amperes
until cells are gassing freely. Do not
exceed24 hours charging time.

b. First Alternative Method: charge battery
at 4-to-6 amperes until cells gas freely.
Do not exceed 8 hours charging time=
C_

SecondAlternative Method: charge the
battery at a rate of 6-to-12 amperes
until cells gas freely. Do not exceed 4
hours charging time.

• Only charge or use the battery in a
well-ventilated area.
• Make sure venting path (vent tube) of
battery is alwaysopen.

Never touchthe positive (+) battery post
and any other surrounding metal with
tools, jewelry, or other metal objects.
Doing so can cause a short circuit that
could result in electrical burns, an electrical shock,or explosionof battery gas.
2. Keep battery clean. If terminals are
corroded, remove battery and clean
terminals with wire brush, sandpaper or
steel wool (Avoid getting any of this
corrosive material on your skin or in your
eyes.) Rinse battery with a solution of
baking soda and water. Coat terminals
with petroleum jelly or silicone greaseto
prevent further corrosion.

• While the battery is being charged,
do not leave it unattended. Charging
time does not have to be continuous.
• Carefullyfollow all charging instructions 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 acid or 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.

Do not charge the battery at a rate
higherthan 12 amperes. A chargerate
greater than this generates excessive
heat and gassing, and will permanently
damage the battery.

6. When battery is fully charged, turn
charging equipment off and disconnect
the cables. Check electrolyte level in all
cells. Add distilled or demineralized water
if necessary to adjust level to the correct
height. Then reconnectthe charger
cables to the battery and chargethe

Cover cable terminal with rubber boot.

4.When engine is still warm, drain oil
from engine crankcase. Refill with flesh
motor oil.

4. Removethe battery holddown clamp
and remove the battery.
5. Reversethe previous steps to replace
the battery. The battery postsmustface
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 disconnect the negative (-) cable first
followed by the positive (+) cable. Reverse this procedure when reinstalling
the battery.

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 internally. Replace spark plug, but do not
reconnect plug wire. Pull rope until resistance is felt -- let rope rewind.
6. Chargebattery (electric start option).
Store battery in cool, dry location.
7. Move Wheels/Tines/PTODrive Lever to
NEUTRALposition. Keep tiller in a clean,
dry area.
8. Never store tiller with fuel in 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.).

Inspecting Forward Interlock
Storing Your Tiller
When yourtiller won't be used during the
off-season, prepare it for storage with the
following steps:
1. Cleanthe tiller and engine.
2. Do routine tiller lubrication and check
for loose hardware.

WiringSystem
Checkthe Forward interlock wiring
system every ten (10) operating hours,
for tight connections and to seethat the
insulation on the wires is unbroken (to
prevent the system from shorting out).

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.
One switch is on the neutral plunger tab
of the cast iron motor mount. This switch
is open whenever the Wheels/Tines/PTO
Drive Lever is in NEUTRALor REVERSE
positions. The other two switches are
located inside the handlebars, directly
abovethe two Forward Interlock Levers.
The switches are wired so when squeezed
(open) the engine will run. There is a
fourth switch located in the wiring
harness connector 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 disconnected wire could
let the engine run without you having to
press one of the Forward Interlock Levers.
2. A bare wire touching tiller or engine
metal could ground out the engine's
ignition.
3. A switch that has failed allows the
engine to run. Or it may prevent the
engine from running.
Refer to the Troubleshootingsection if
your Forward Interlock SafetySystem is
not operating correctly.

AppendixB: Attachments& Accessories
Troy-Bilt® PTO Chipper/Shredder

Dozer/Snow Blade Attachment

V-Sweep Cultivator

The Troy-Bilt_ PTOChipper/Shredder
provides a convenient, easy means of
cleaning up unsightly brush piles and
other organic matter on your property,
with the added bonus of providing an
unending supply of useful wood chips,
mulch and compost for your landscaping
and gardening needs.

In the winter, moves up to one foot of
light snow (or 6"-to-8" of heavy snow); at
other times use it to move or spread
sand, gravel, loose dirt, grain, sawdust,
etc. Attaches easily to the front of the
Wrap-Around Bumper Guard. Set the
blade to several angles. Weighs 41-1bs.;
measures 15"x 32".

The V-SweepCultivator is a specialized
tool designed for between-row crop cultivation. Instead of stirring the soil, it
slices through just below the surface to
eliminate practically any weeds in its path.

The unit connects quickly to your tiller
and goes wherever your tiller can go. The
swivel wheel on the back of the unit

HilleriFurrower Attachment

rotates for extra maneuverability. When
you've finished your chores, the
Chipper/Shredder stands by itself on its
own built-in stand.
The PTOChipper/Shredder can chip
limbs, stalks and vines up to 3" in
diameter, and can 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 means of
splitting about a half a cord of wood per
hour when working alone. When
connected to the PTOPower Unit, the
tiller's engine runs the splitter's hydraulic
pump, providing you with 13 tons of
steady, unhurried and predictable splitting
force.
As an added 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 along the woodpile to a fresh
supply of logs.
Featuresinclude a 15 second splitting
cycle; can handle log sizes up to 26" long;
a two-stage hydraulic pump that automatically shifts into low gear to provide fourtimes greater pressure when needed;
slim-cut wedge design for splitting green,
stringy wood; and an auto-control valve
for automatic return stroke.

The Sweepmounts easily to the optional
Tow Hitch Attachment at the rear of the
PTOPower Unit. The blade is made of
high carbon, heat treated steel and
measures 2"wide (overall wing span is

The most popular attachment because it
does so many-jobs. Mounts to the rear of
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. Converts from a furrower to a
hiller and back again, in seconds, without
tools.

20"),

Row Marker Attachment

The Sweep's natural shallow cultivation
helps to prevent weed seeds from being
brought to the soil's surface. This
shallow cultivation feature also means
there's less chance of damaging the roots
of your vegetables. For deeper or more
shallow cultivating, the blade depth can
be changedwith a simple adjustment_

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 need for 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"-to49_ ", letting you vary the width between
rows to suit the crop you're planting.
Tire Chains
Chains provide extra traction when snowplowing, or under wet or slick conditions.

The unique way the Sweepworks,
skimming along.just underneath the soil's
surface without turning the soil over,
makes this the ideal tool 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.

Wheel Weights
Help increasetraction by putting extra
weight directly on the wheels. They
reduce bucking and-jumping when deeptilling in heavy soil. They're shipped
empty- fill them with material like
concrete, sand, gravel, etc. They bolt
directly to the tiller wheels.

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.

Wrap-Around Bumper Guard
Order this Bumper Guard by itself or
receive it as one of the components if you
order the combination Dozer/Snow Blade
attachment. Protects the engine from
damage by wrapping around and protecting many of the engine components. 1"
diameter, high-strength steel tubing.
