PTOAttachmentsFeature
In addition to powerful tilling capability,
you can quickly convert your machine
into a PTO(Power Take-Off) Power Unit
that is capable of towing or powering
various TROY-BILTattachments.
You can access this capability by
removing the tines attachment (powered
by the PTOPower Unit). The PTO Power
Unit is then availablefor engine powered
attachments, or for pulling or towing nonpowered attachments. See Section 4,
PTO Power Unit for detailed information
on installing and operating TROY-BILT
PTOattachments.

WheelsiTines/PTODriveLever
Use the Wheels/Tines/PTODrive Lever (A,
Figure 3-1) to engage and disengage
power to the transmission.

whentransporting the machineon level
ground without engine power, and when
using stationary PTOattachments.
IMPORTANT: To avoid transmission
damage, always move Wheels/Tines/PTO
Drive Lever into NEUTRALbefore shifting
the Wheel Speed Lever.
IMPORTANT: When shifting into SLOW
or FAST, gently roll the machine forward
or backward to help fully engage the
wheel gears. When engaged, the wheels
will not turn unless the engine is running
and the Wheels/Tines/PT0 Drive Lever is
engaged in FORWARDor REVERSE.

• DISENGAGE
- Lever moved into detent
slot nearestengine. Usethis position to
disengagepower to tines or other PTO
attachmentsbeforetransporting, loading,
turning, or operating in reverse.

Use this lever (E, Figure3-1) to regulate
the tilling depth of the tines. This control
also has a TRAVELposition, which
enables transport with the tines off the
ground.
To operate the lever, lift up on the handlebars, pull the Depth Regulator Lever
straight back, and then slide it up or down
to one of the eight detent height settings.
The eight detent positions offer a range of
tine height settings. This enablesyou to
select the height that is most effective for
a particular condition. The top detent
position is the TRAVELsetting. Usethe
second or third detent from the top for
shallow tilling and cultivating. Use the
other detents for deeper tilling and for
power composting.

To
avoid
personal
injury,
always place the tines in the TRAVEL
position before starting the engine.
This prevents the tines from touching
the grounduntil you are ready to begin
tilling.

The following pages provide 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
Wheels/Tines/PTODrive Leverdown to
FORWARDposition.

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

Section4: Operation
MakingTurns
Turningthe tiller is easy and just requires
practice. First find the balance point
betweenthe engine and the tines by lifting
up the handlebars (Figure4-5). Onceyou
find the balancepoint, then let the
poweredwheels do the turning as you
pushsideways on the handlebars in the
direction of theturn. Practice theturning
maneuver described here in a large open
area. Oncecomfortable 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 Wheels/Tines/PTO
Drive Lever down to FORWARD.

1. At the end of a row, move the Wheels/
Tines/PTO Drive Lever (Figure 4-2) to

that is not yet tilled (Figure4-4). 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.

StoppingForwardMotion 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
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.

Do not till

while

1. Shift the Tines/Wheels/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/Tines/PTODrive Lever all the way
up and hold. You do not need to squeeze
the Forward Interlock Leversto use
mve_e.

2. Move the Tines/PTOClutch Lever
(Figure4-2) into the DISENGAGE
position.
3. Resumeforward operation, and lift
handlebarsuntil tines are off the ground
(Figure4-5). Findthe balancepoint
betweenthe engine and the tines. Then
pushthe 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 poweredwheels do the
hard work. The inside wheel will pivotin
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.(The Forward
Interlock Levers will not stop REVERSE
motion.)

Transporting The Tiller Around
Your Property
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.

To help avoid personal injury from
revolving tines, always put the
Tines/PTO Clutch Lever in DISENGAGE
positionbefore transporting,loading, or
unloadingUiler.
1. Placethe Tines/PTOClutch Lever in
DISENGAGEposition.

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.

Howto Checkthe Interlock System
The Forward Interlock System has an
electro-mechanical design, and so is
subject to normal wear and possible malfunction. Checkthe system for proper
operation each time prior to using the
tiller or PTOpower unit.

2. Move Depth RegulatorLeverdown all the
way into the Travel setting.

4. If the engine is stopped, move Wheel

5. Squeezeand hold just 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 PTO powerunit until the
system has been repaired and is functioning properly.
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.

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

Interlock Safety System
The Forward Interlock Safety System is
designedto 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 release both
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.

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.

• 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 havea
locking device to secure them to the
vehicle.
• Handlers should wear sturdy footwear
that will help to prevent slipping.

Section4: Operation
• Turn the vehicle's engine off and apply
its parkingbrake.

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.

Loadingthe Tiller
1. 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/PTOClutch 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 reducethe
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/PT0
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.

Figure 4-7: To go up ramps, use
FORWARD drive.

Unloading the Tiller
IMPORTANT: Never unload the tiller in
FORWARDdrive. The tiller could tip
forward and expose you to the tines
(which should be disengagedas
instructed).
1. 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.

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

Pulley

Figure 4-9: Belt 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 SLOWand FAST,
as set with the Wheel Speed Lever.
Table 4-1 shows the range of wheel and
tine speeds available when using the two
belt speed rangesand the FASTand
SLOWselections on the Wheel Speed
Lever.

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

Changing Speed Belts
Your tiller has two belt-driven speed
ranges - HIGH RANGEand LOW RANGE
- you pick one or the other by deciding
which set of pulley grooves to move the
forward belt into. By moving the belt
from 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
downbeforechangingbelt speeds.

ChoosingWheel
and Tine Speeds
Your tiller has four FORWARDwheel/tine
speed combinations for handling a variety
of tilling tasks and gardening jobs. 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 Regulatortoo 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 steady and smooth.

and procedures.

7. Checkthat the belt is fully seated in the
pulley grooves. Checkthis from both
sides of the tiller.

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 poweredwheels, 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 inchor two deep) for the first
passesthrough the garden area.

With each succeeding pass,adjust the
depth regulator to dig another inchor
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 (breaking up the
surface soil around plants to help
destroy weeds), use very shallow depth
settings to preventinjury to plantswhose
roots often grow closeto 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 better moisture
absorption and faster plantgrowth.

Avoidtilling wet, soggysoil
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.

To help avoid personalinjury, be aware
that the tiller can unexpectedlybounce

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 hand onthe handlebars,
relaxing your arm but with a secure
hand grip.
• Use shallow depthregulator settings.
Till graduallydeeper.
• 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 diggingtoo deeply.
• 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
reach the lever or have lost control, Let
Go OfThe Handlebarsand All Controls. 21

Section4: Operation

Tilling Tips & Techniques
Avoidmakingfootprints
When possible,walk on 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 passesby onehalf a tiller width, followed by successive passesat one-quarter width
(Figure 4-16).
• With planning, you can allow enough
room between rows to cultivate
(Figure 4-17). Leave room 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:
1. 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 handlebarsslightly
while going uphill. When going
downhill, overlap the first pass by
about one-half the width of the tiller.
HINT: For best results, usethe 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
goodfooting.
• Wear footwear that increases

Figure4-14

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

]

Figure4-15

• 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 prevent engine 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 your engine after every onehalf hour of operation.

Figure4-16

Section4: Operation

Tilling Tips & Techniques
Clearingthe tines
The tines havea self-clearing action
which helps to eliminate most tangling
of debris. However, occasionally dry
grass, stringy stalks or tough vines may
become tangled.
Follow these procedures to help avoid
tangling and 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
couldresult in personal injury.

Figure 4-18
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
terraced rows. Terracesare rows that
are cut into the side of a slope, creating
a narrow, but flat area on which to
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 keepthe 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 terracing gardening 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 terraced rows or till
vertically.
• Move the belt into LOW belt range and
the Wheel Speed Gear Lever to SLOW
position. As in terrace gardening, start
at the top of the slope and overlapthe
first pass by halfthe width of the tiller.
Foradded stability, keepthe 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 reducetangling, 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.

Section4: 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 jumpsor 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 comply could 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.

1. 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 (Figure 4-19). Do not usethe
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 aside for 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 deeptilling.
Use either LOW or HIGH belt 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.

key, if so equipped.
Failure to follow these instructionscan result in serious personalinjury or propertydamage.

Tighten Bolts and Nuts
Checkfor loose or missing hardware
every ten (10) operating hours. Failureto
tighten or replacefasteners can cause
poor performance, equipment damage or
oil leakage. See your Parts Catalog for
complete fastener descriptions.

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
reachthe bolts, remove the left side tine
holder. See Bolo Tine Maintenancein this
Section for tine holder removal directions.

Most hardware on your tiller is visible.
Pay particular attention to hardware
shown in Figures 5-1,5-2, 5-3 and 5-3A.

5. Check both swing-bolts (C, Figure5-3)
that connect the power unit transmission
to the tine attachment. Both bolts should

1. Checkthe transmission pulley
mounting bolt (Figure 5-1). If the washer
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
mounting bracket (A, Figure 5-3). If any
is loose, it can cause an oil leakor drive
shaft end play.

Figure 5-1: Check bolt on transmission

be checked every 2-1/2 hours of
operation. If loose, wear can occur on the
locating pin on the power unit, and cause
enlargement of the locating hole in the
tine attachment. Using a torque wrench,
tighten these bolts to 70-to-80 ft.-Ibs.
6. Checkthe Iocknut that fastens the

IMPORTANT: Give screws or bolts that
go into the transmission housing a
coating of non-hardening gasket sealant
to prevent gear oil from leaking.

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
grease.

IMPORTANT: Do not allow oil or grease
to contact the pulleys, drive belt or
reverse disc. This can cause the belt or
disc to slip on the pulleys.
Lubricate the numbered areas in Figures
5-4 and 5-5, as follows:
1. Oil the wheel shaft betweenthe wheel
hubs and the transmission housing
(A, Figure5-4).
2. Oil all pivoting and connecting points
on the Wheels/Tines/PTODrive Leverand
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,

in PTO access area.

The vents allow small amounts of oil to
seep out.
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
1. The transmissionsmust be cool,
since hot gear oil expands and gives a
false reading.
2. The power unit transmission and the
tine attachment transmission must be
connected when checking (or adding)
gear oil.
Checkingthe Power Unit Oil Level
1. Move the tiller to level ground. Move
the Depth Regulator up so the tines rest
on the ground.
2. Use a 3/8" wrench to remove the oil
level check plug on the left side of the
transmission housing (Figure 5-7).

Section5: Maintenance
Before inspecting,cleaning or servicingthe machine, shut off engine, wait for all moving parts to come
to a complete stop, disconnectspark plug wire and move wire away from spark plug. Remove ignition
key, if so equipped.
Failure to follow these instructionscan result in serious personalinjury or propertydamage.
For Dipsticks With 'CheckCold' Marking
(Cold means 2 hours has passed since
the tiller was used.)
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).

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 the check plug. If
no oil seeps out, see Adding 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 4-1/2" 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 touch the 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 usedas props.
9. If oil level was low, gear oil must be
added before using the tiller. See Adding
or ChangingGear Oil next.
For DipsticksWithHot/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 attachment transmission) must face rear.

4. Cold reading (preferred method):
(Two hours has passed since the tiller
was used.) Placea 2" x 4" board (on
edge) under the drag bar- raising the tiller
and drag bar about 3-1/2" above ground.
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 abovethe "Cold"
range marking if taking a cold reading. If
taking a hot reading, the level should be
within or slightly above the "Hot" range.
7. If the level is incorrect, see Adding or
Changing Gear Oil.

Addingor ChangingGear 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
of GL-4 or 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
12-1/2" ozs.

Drive Belt Maintenance
Measuringand Adjusting
DriveBelt Tension
Ona newtiller (or if a newbeltis
installed),the belttensionwill probably
needto beadjustedafterthefirst two (2)
hoursof operation.Thereafter,checkbelt
tensioneveryten (10)operatinghours.
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"4o-5/16" away
from the face of the upright bracket that
holds the adjustment block in place
(Figure 5-12). To measure this distance:
a.

Without moving the clutch roller, try
inserting the 1/4"-thick, slotted end
of the belt adjustment tool in
betweenthe roller and the upright
bracket. (The flat edge of the tool
must be facing the roller.) Refer to
Figure5-13.

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 toAdjust Belt Tension

• Keep tension adjusted 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 adjustment tool to measure and adjust
drive belt tension.

1. As described in the following steps,
drive belt tension is adjusted by moving
the adjustment block up or down.
Moving it down will tighten the belt;
moving it up loosens the belt.
HINT: The distance the block moves

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).
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.

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

approximately equals the distance the
roller moves.
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/PT0 Drive
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.

8. Checkthe tension on the belt by
following the previous instructions "How
to Measure Belt Tension."
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

Failure to follow these instructionscan result in serious personalinjury or propertydamage.
Reverse Disc Inspection
The reverse disc is made of steel with a
special, long-lasting rubber compound
bonded to the disc rim. Sincethis is a
wearing part, it should be inspected after
every 30 operating hours.

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

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

1. Measurethe width of the outside edge
of the disc as shown in Figure5-22.
Replacethe disc before the rubber edge
wears to a thickness of 1/8" or less.
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 slack is needed,hold up
Wheels/Tines/PTODrive Lever while
moving the belt. Verify the belt is seated
properly on the pulleys.
8. To move the belt to the LOW Range
position, see Changing Belt Speedsin

ReverseDrive
System Maintenance
These instructions explain how to inspect,
replace or adjust the various 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 the transmission drive pulley.
The friction between the rotating reverse
disc and the transmission pulley causes
the transmission drive shaft to be
powered in a counterclockwise direction
(as viewed 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
_

Before inspecting,cleaning or servicingthe machine, shut off engine, wait for all moving parts to come J
to a completestop, disconnectspark plug wire and move wire away from spark plug. Remove ignition J
key, if so equipped.

Failure to follow these instructionscan result in serious personalinjury or propertydamage.

Replacingthe ReverseDisc
Follow these steps to replace the reverse
disc. (If your tiller hasa Bumper Attachment mounted, it must be removed first.)
Removingthe Reverse Disc
1. Move Wheels/Tines/PTODrive Lever in
NEUTRALposition.
2. Wedge a 5/16"-thick board between top
of engine pulley (avoid contacting reverse
disc) and cast iron housing next to it.
This immobilizes pulley.
3. Usea 9/16" wrench to loosen the
mounting bolt shown in Figure5-23.
Rememberto immobilize the pulley with
the wood wedge while loosening the bolt.
If necessary,pry the disc from the pulley
with the tip of a screwdriver. 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.
When you 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.
When the lever is in NEUTRAL,the switch
body on the bottom of the engine mount
tab should be resting squarely on top of
the reverseadjustment bolt (Figure 5-24).
The reverseadjustment bolt can be
adjusted up or down to correct a number
of reverse drive operating problems, as
explained next.

Figure 5-24: Spring and plunger
assembly.
Figure 5-23: Removing Reverse Disc.

Installing a New Reverse Disc
1. Do steps 1-through-3, described previously, in reverse.
2. Tighten mounting bolt securely, and
check for correct operation -- see

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.

CheckingandAdjustingReverse Disc
1. Verify that linkagesfor
Wheels/Tines/PTODrive Lever are lubricated with oil and engine mount bars and
belt adjustment block are lubricated with
grease. (See Tiller Lubrication in this
section.)
2. PlaceWheels/Tines/PTODrive Lever in
NEUTRAL. Briefly pull out engine recoil
start rope while watching reverse disc.
The disc should turn, but lower pulley
should not (Figure 5-25). If reverse disc
turns lower pulley, or if it is located closer
than 3/16" to the pulley, reverseadjust-

Figure 5-26: Checking Reverse Disc
in REVERSE.

4. Shift the Wheels/Tines/PTODrive Lever
to REVERSEand then let it go. The lever
should return to NEUTRAL. If not, the
reverse adjustment bolt will have to be
adjusted upward.

Section5: Maintenance
Before inspecting,cleaning or servicingthe machine, shut off engine, wait for all moving partsto come
to a complete stop, disconnectspark plug wire and move wire away from spark plug. Remove ignition
key, if so equipped.
Failure to follow these instructionscan result in serious personalinjuryor propertydamage.
AdjustingReverse Drive:
1. PlaceWheels/Tines/PTODrive Lever in
FORWARDposition.
2. On left side of tiller, put a 1/2" wrench
on the plunger retaining bolt and another
1/2" wrench on the jam nut next to it
(Figure 5-27). While holding the bolt
steady, loosen the jam nut (counterclockwise) until it touches the bolt head.

7. Placea chalk or pencilmark on the top
edge of the plunger retaining bolt. Now,
while watching the 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).

Bole Tine Maintenance
CheckingTinesfor Wear
Inspect the tines for wear or damageafter
every 30 operating hours. The rate of
wear depends upon hours of useand soil
conditions. With use, the tines get
shorter, narrower and more pointed
(Figure 5-30). If badly worn, they lose 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 wrench while tightening the jam
nut against the side of the plunger housing
(Figure5-27).

3. Turn the bolt in until it tightens against
the plunger insidethe spring. The bolt
must be tight to preventplunger from
turning - but be careful not to overtighten
and break the bolt.

Figure 5-30: Check for wear
every 30 operating hours.

Worn tines leavean ever-increasing gap
in the middle of a tilled row. The normal
gap is 3" between the tine tips - replace
the tines when the gap widens to 5"
(Figure 5-31 ).

4. Placea 7/8" wrench on the head of the
reverse adjustment bolt and a 9/16"
wrench on the jam nut below it (Figure 528). Hold the bolt steady while loosening
the jam nut three or four turns.
5. Move the Wheels/Tines/PT0 Drive
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. Checkthat reverse disc is at least 3/16"
away from transmission drive pulley.
Then hold reverse adjustment bolt steady
with one wrench while tightening jam nut
with a second wrench (Figure 5-28).

Figure 5-29: Loosen plunger
retaining bolt about 3/4-turn, then
tighten jam nut against plunger
housing.

9. Checkthe action of the reversedisc as
explainedpreviously.
IMPORTANT: If the above adjustments
have not corrected an improperly working
reverse drive, contact an authorized
dealer or Factory Technical Service
Department for assistance.

efore inspecting, cleaningor servicingthe machine, shot off engine, wait for all moving parts to come
to a complete stop, disconnectspark plug wire and movewire away from spark plug. Remove ignition
key, if so equipped.
Failure to follow these instructionscan result in serious personalinjuryor propertydamage.

Tine Shaft Maintenance
After every 10 operating hours, remove
the left- and right-side Bolo Tine holders
and clear away dirt and debris that have
accumulated on the tine shaft or inside
the tine holders. Pleasefollow this maintenance recommendation, as debris can
cause premature wear to the tine shaft
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 10-to-20 psi (pounds per square
inch). Both tires should be inflated
equally. (Unequal pressure can cause the
tiller to pull to one side.)

Removingthe 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 (10) operating hours and even
sooner when operating in extremely dirty
or dusty conditions. Refer to the separate
EngineOwner's Manual for detailed
service instructions.
Air Cleaner Maintenance
The engine is equipped with a dual
element air cleanerthat filters the air
twice before it enters the carburetor to
mix with the fuel.
The engine air cleaner filters dirt and dust
out of the air before it enters the carburetor. Operatingthe engine with a dirty,
clogged air filter can cause poor performance and damage to the engine. Never
operatethe engine without the air cleaner
installed. Inspect and service the 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 maintenanceinformation.

2. Move the Wheel Speed Lever to either
SLOW or 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 hob to
protectyour eyes from the possibilityof
flying metal particles.

The throttle lever settings are factoryadjusted, so unnecessary adjustments
should not be made. 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.

Spark PlugMaintenance
The spark plug must be in good condition
for proper engine operation. Removeand
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 usea
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 1/4
turn.

Battery Care and Maintenance
Theb_tery is sealedandis maintenencefree.Acid levelscannotbechecked.
• Always keepthe battery cables and
terminals clean and free of corrosive
build-up.
• After cleaning the battery and
terminals, apply a light coat of
petroleum jelly or greaseto the
terminals and cover both terminals
with the rubber boots.

When removingthe battery, always disconnect the negative (-) cable first
followed by the positive (+) cable. Reverse this procedure when reinstalling
the battery.

IgnitionSystemMaintenance
EngineOil 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.

Before inspecting,cleaning or servicingthe machine, shut off engine, wait for all moving parts to come
to a complete stop, disconnectspark plug wire and move wire away from spark plug. Remove ignition J
key, if so equipped.

Failure to follow these instructionscan result in serious personalinjuryor propertydamage.

StoringYour Tiller
When your tiller 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.
3. Protect the engine from deterioration
or damage by referring to the engine
storage instructions in your engine
manual literature.
4. When engine is still warm, drain oil
from engine crankcase. Refill with fresh
motor oil.
5. Protect internal cylinder against rust by
removing spark plug and pouring one
ounce of clean engine oil into spark plug
hole. Then slowly pull out recoil start
rope 2 or 3 times to distribute oil internally. Replacespark plug, but do not
reconnect plug wire. Pull rope until resistance is felt -- let rope rewind.
6. Charge battery (electric start option).
Store battery in cool, dry location.
7. Move Wheels/Tines/PTODrive Lever to
NEUTRALposition. Keeptiller in a clean,
dry area.
8. Never store tiller with fuel in fuel tank
in an enclosedarea where gas fumes
could reachan open flame or spark, or
where ignition sources are present (space
heaters,hot water heaters,furnaces, etc.).

Inspecting Forward Interlock
Wiring System
Checkthe ForwardInterlockwiring
systemeveryten (10) operatinghours,
for tight connectionsandto seethatthe
insulationonthe wires is unbroken(to
preventthe systemfrom shortingout).
1. Checkinsulated wire harness from
lower ends of handlebarsto wire harness
connector on top, right side of transmission cover. Be sure connector is secure.
2. Checkinsulated tubing from connector
to cast iron motor mount/belt shroud.
3. Checkthe wire leading from the tubing
over to the switch assembly mounted on
top of the tab on the cast iron motor
mount-belt shroud. Also check the
second wire that leads to the throttle
cable mounting bracket on the right side,
forward portion of the engine.

Testingthe Forward
Interlock WiringSystem
The wiring circuit for the Forward
Interlock SafetySystem is designed to
ground out the engine's ignition system.
There are three switches in the circuit
which, when open, let the engine run.
Oneswitch is on the neutral plunger tab
of the cast iron motor mount. This switch
is open whenever the Wheels/Tines/PTO
Drive Lever is in NEUTRALor REVERSE
positions. The other two switches are
located inside the handlebars, directly
above the 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 Safety System is
not operating correctly.

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.

Do you like very straight, even, neat rows
in your garden? If so, the Row Marker is
a must attachment. Hooks quickly to the
Hiller/Furrower attachment- eliminates

Help increase traction by puttingextra
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.

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.

Dozer/Snow Blade Attachment
290-259-081
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 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 extendsfrom 28"-to49¾",letting you vary the width between
rows to suit the crop you're planting.

V-SweepCultivator
290-260-081
The V-Sweep Cultivator is a specialized
tool designedfor 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 Sweep mounts easily to the optional
Tow Hitch Attachment at the rear of the
PTOPower Unit. The blade is madeof
high carbon, heattreated steel and
measures 2" wide (overall wing span is
20").
The unique way the Sweepworks,
skimming along just underneaththe 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

Wrap-AroundBumperGuard
290-255-081
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
damageby wrapping around and protecting many of the engine components. 1"
diameter, high-strength steel tubing.

Hiller/FurrowerAttachment
290-250-081
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.

speed.
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 changed with a simple adjustment..
