WARNING TO ALL CALIFORNIA
AND OTHER POWER EQUIPMENT OPERATORS
Under California law, and under the laws of several other states,
you are not permitted to operate an internal combustion engine
using hydrocarbon fuels on any forest-covered, brush-cov-
^ ered, or grass-covered land, or on land covered with grain,
^ \ hay, or other flammable agricultural crop, without an en
gine spark arrester in continuous effective working order.
The engine on your power equipment, like most outdoor power equipment, is an
internal combustion engine that burns gasoline, a hydrocarbon fuel. Therefore,
your power equipment must be equipped with a spark arrester muffler in continu
ous effective working order. The spark arrester must be attached to the engine
exhaust system in such a manner that flames or heat from the system will not ig
nite flammable material. Failure of the owner/operator of the equipment to com
ply with this regulation is a misdemeanor under California law, and may also be a
violation of other state and/or federal regulations, laws, ordinances, or codes.
Contact your local fire marshal or forest service for specific information about
what regulations apply in your area. Contact your authorized engine dealer for in
formation about obtaining a spark arrester.

12. Keep children and pets away.
Page 7
13. Never operate the tiller under
engine power if the Wheel Speed
Lever is in the FREEWHEEL posi
tion. In EREEWHEEL, the wheels
will not hold the tiller back and the
revolving tines could propel the
tiller rapidly, possibly causing loss
of control. Always engage the
Wheel Speed Lever in either EAST
or SLOW position before starting
the engine or engaging the tines
with the Wheel s/Tines/PTO Drive
Lever.
14. The tiller could unexpectedly
bounce upward or jump forward
and be propelled away from you if
the tines strike or catch very hardpacked soil, sod, frozen ground, or
any buried obstacle such as large
stones or roots. Let go of the han
dlebars and all controls. Do not try
to restrain it. If in doubt about till
ing conditions, use the following
precautions to assist you in main
taining tiller control:
a. Walk behind and on either
side of the tiller, using one
hand on the handlebars.
Relax your arm, but use a se
cure hand grip.
b. Use shallow depth regulator
settings, gradually working
deeper with each tilling pass.
c. Use slower wheel, tine and en
gine throttle speeds.
d. Clear the tilling area of big
stones, roots and other debris.
e. Avoid putting downward pres
sure on the handlebars. If
necessary, apply slight upward
pressure to prevent the tines
from digging too deeply.
f. Avoid contacting hard-packed
soil or sod at the end of a row
by reducing engine speed and
lifting handlebars up to raise
tines out of the soil.
g. In an emergency, stop the
tines and wheels by shifting
the Wheels/Tines/PTO Drive
Lever to NEUTRAL. If you
can not reach the lever or have
lost control of the tiller, let go
of the handlebars and all con
trols. Do not try to restrain it.
15. Do not overload the machine
capacity by trying to till too deeply
at too fast a rate.
16. Never use the tiller at high
ground speeds on hard or slippery
surfaces. Look behind and use care
when backing up.
17. Do not operate tiller on a slope
too steep for safety. On slopes,
slow down and be sure you have
good footing. Don’t let the tiller
“free-wheel” down slopes.
18. Clear the area of bystanders be
fore tilling.
19. Use only attachments and acces
sories approved by Garden Way Inc.
20. Use tiller attachments and ac
cessories when recommended.
21. Never operate the tiller without
good visibility or light.
22. Never operate the tiller if you
are fatigued, or under the influence
of alcohol, drugs or medication.
23. Operators shall not tamper with
the engine-governor settings on the
machine; the governor controls the
maximum safe operating speed and
protects the engine and all moving
parts from damage caused by over
speed. Authorized service shall be
sought if a problem exists.
24. Do not touch engine parts that
may be hot from operation (muffler,
fins, etc.). Make certain all parts
have cooled down before inspect
ing, cleaning or repairing.
25. POISON/DANGER—
CAUSES SEVERE BURNS. The
battery on electric start models con
tains sulfuric acid. Avoid contact
with skin, eyes or clothing. Keep
out of reach of children.
Antidotes: External- Elush imme
diately with lots of water.
Internal- Drink large quantities of
water or milk. Eollow with milk of
magnesia, beaten eggs or vegetable
oil. Call a doctor immediately.
Eyes- Flush with water for 15 min
utes. Get prompt medical attention.
26. DANGER-BATTERIES
PRODUCE EXPLOSIVE
GASES. Keep sparks, flame or
smoking materials away. Ventilate
when charging battery or using in an
enclosed space. Always wear safety
goggles when working near battery.
27. Remember—To stop tines and
wheels, either put Wheels/
Tines/PTO Drive Lever in NEU
TRAL, or move Throttle Lever to
STOP position. If you lose control
of the tiller and can not reach the
levers, let go of the handlebars and
controls and do not try to restrain
the tiller. The Forward Interlock
Safety System will stop the engine.
28. Look behind and exercise cau
tion when backing up. For added
safety, put Wheel Speed Lever in
SLOW position before reversing.
29. When loading or unloading the
tiller, always disengage tines and
use slower wheel and engine throt
tle speeds. Use sturdy ramps wide
and strong enough to easily support
the tiller (280-to-325 lbs., depend
ing on model) and operator. Never
go down ramps in FORWARD
drive—the tiller could tip forward,
exposing you to the tines (which
should be disengaged). Always
use REVERSE drive and back down
ramps. To go up ramps, use FOR
WARD drive and follow the tiller.
30. The Forward Interlock Safety
System should be tested for correct
functioning every time the tiller or
pro power unit is used. See
Section 4 in this Manual.
31. If using the optional Dozer
Blade, either remove the tine attach
ment, or disengage the tines with
the Tines/PTO Clutch Lever.
Revolving tines are dangerous.
32. Use extreme caution when re
versing or pulling machine towards
you.
33. Start the engine carefully ac
cording to instructions and with feet
well away from the tines.
34. Never pick up or carry a ma
chine while the engine is running.

STEP 6: Check Gear Oil Levels in Power Unit Transmission and Tine Attachment Transmission
Your tiller has two separate
transmissions: one for the Power
Unit; the other for the Tine Attach
ment. Both were filled with SAE
#85W-140 weight gear oil (with
an A.P.I rating of GL-4) at the
Factory. Please check level in both
transmissions to verify that levels
are still correct.
To Check Power Unit
Transmission:
A. Put the tiller on level ground.
B. Pull Depth Regulator Lever
back and then up so tines are rest
ing on the ground (Photo 2-15).
C. Use a 3/8" wrench to remove
oil level check plug on left side of
the transmission (just above the
wheel shaft). See Photo 2-16. You
may need to break the grip of any
dried paint on the check plug.
D. Oil should seep out hole if
level is correct (in cold weather, it
will seep out slowly). Reinstall
plug securely if gear oil level is
correct.
E. If no oil seeped out, see if tilt
ing tiller slightly toward check
hole (roll right wheel on a 1" thick
board) causes oil to seep out. If oil
starts to seep, only a, small amount
should be added. But - if there is
still no oil seeping out, the oil level
may be seriously low. In either
case, add the correct amount of
gear oil before using the tiller —
see “Adding or Changing Gear
Oil” in Section 5 of this Manual.
To Check Tine Attachment
Transmission:
Two different gear oil level
checking procedures for the tine
attachment transmission follow.
Use the procedure described first
for Tine Attachment dipsticks
with a ‘Check Cold’ marking.
Use the second procedure if dip
stick has both ‘cold’ and ‘hot’
markings at end. First remove
dipstick from tine transmission
(Photo 2-17) to see which type
dipstick you have. Then replace
dipstick.
For Dipsticks With ‘Check Cold’ IVIarkina:
A. Put the tiller on level ground.
B. Pull Depth Regulator Lever
back, then push it down all the way
to engage its top notch. This raises
tines off ground and lets tiller rest
on drag bar.
C. Place a support under engine to
prevent tiller from tilting too far.
Now slide three pieces of 2" x 4"
lumber under drag bar - raising
drag bar about 4-1/2" above
ground. This elevation is needed
to take an accurate “cold” gear oil
reading (“cold” means tiller was
never operated, or 2 hours have
passed since it was used last).
D. Wait two hours with tiller ele
vated (allow more time if tempera
ture is below 40°F).
E. Loosen and remove transmis
sion dipstick. (Photo 2-17). Wipe
with a clean rag.
F. Holding dipstick so markings
face rear of tiller, lower it straight
down into sump hole until it
touches driveshaft inside (Photo 2-
17). Don’t force or try to thread it
back in - or reading won’t be cor
rect.
G. Remove dipstick and check oil
level. It should be within crosshatched area or even slightly above
the ‘Max’ marking. If correct, re
place dipstick and remove boards.
H. If no oil showed on dipstick,
correct amount of oil must be
added to tine transmission. For
complete instructions, see “Adding
or Changing Gear Oil” in Section 5
of this Manual.
For Dipsticks With Hot/Cold Markings:
A. Follow Steps A and B given for
other type of dipstick.
B. Put one 2"x4" board under drag
bar- raising tiller and drag bar
about 3-1/2” above ground. This
elevation is for a ‘cold’ gear oil
reading (tiller never used or 2
hours since used last).
C. Follow Steps D, E, and F given
for other dipstick type.
Photo 2-15: Pull Depth Regulator
Lever back and then up to lower
the tines to the ground.

Photo 2-17: Remove dipstick to
check gear oil in tine attachment
transmission. Insert dipstick so
markings face rear of tiller.
Page 15
D. Remove dipstick and check
that gear oil level is within or
above ‘Cold’ range marking (use
of ‘Hot’ marking is explained in
Section 5). If correct, replace dip
stick and remove the board.
E. If the level is incorrect, see
“Adding or Changing Gear Oil” in
Section 5 of this Manual.
IMPORTANT
Recheck gear oil level in both trans
missions after the first two hours of
new tiller operation, then every 30
operating hours thereafter. See
Section 5 for instructions.
STEP 7: Add Motor
Oil to Engine
Add high-quality API-rated
“SF” or “SG” motor oil to engine
before starting. Refer to the Engine
Owner Manual provided with your
unit for motor oil specifications and
capacities.
To Add Oil:
A. Park the tiller on level ground.
Place a sturdy block under the drag
bar at the rear of the tiller to level
the base of the engine.
B. An oil fill tube is located on
each side of the engine. Either can
be used. See Photo 2-18.
C. Clean around the oil fill tube and
remove the oil fill plug. Use a clean
funnel and slowly pour motor oil
into the tube until the oil reaches the
top of the fill hole.
D. Reinstall the oil fill plug and re
move the block under the drag bar.
IMPORTANT:
> Always maintain oil level at the
overflow point in the oil fill tube.
' Check engine oil level every 5
hours of operation or daily.
' Change engine oil after first 5
hours of new operation.
Photo 2-18: Add
oil until it reaches
top of oil fill tube.
STEP 8: Attach Engine Throttle
Lever to Right Handlebar
The throttle cable (with throttle
lever) is wound around the engine
for shipping purposes. Carefully
unwind the cable. If the throttle
control decal is covered with a pro
tective coating, peel it off. Attach
the lever as follows.
A. You will need the curved head
bolt, flange locknut, panhead
screw and two plastic ties which
are shown in Photo 2-2, Page 10.
B. Run the throttle cable up the in
side edge of the right handlebar
and position the lever as shown in
Photo 2-19.
C. From the outside of the handle
bar, insert the curved head bolt
through the handlebar and the cen
ter hole in the throttle lever mount
ing bracket.
D. Loosely install the locknut.
E. Move the throttle lever to the
STOP position.
F. From the lever side of the
bracket, thread the panhead screw
into the small hole in the throttle
lever bracket and into the handle
bar. See Photo 2-19. Tighten the
screw securely.
G. Use a 7/16" wrench to securely
tighten the locknut and the curved
head bolt.
15
H. Using two plastic ties, secure
the throttle cable to the right han
dlebar in two places, as shown in
Photo 2-20. Loop each tie around
the handlebar and cable (serrated
side faces in) and pull the ties
tight. Trim the ends.

places to hold cable to handlebars.
WARNING
On electric start tillers, to
avoid electric shock from a
short circuit, never allow
throttle cable to touch the
battery. Route cable below
the battery, on the outside of
the battery holder.
STEP 9; Adjust the Air Pressure
in the Tires
A. For shipping purposes only, the
tires are overinflated.
B. Before using the tiller, check
the air pressure and adjust it to betiveen 10-to-20 psi (pounds per
square inch). Each tire should be
inflated to the same pressure.
Important
If you have a recoil start tiller,
it is now completely assem
bled. If you have an electric
start tiller, please continue
with the few remaining steps.
ASSEMBLING THE ELECTRIC START SYSTEM
The following steps explain battery activation, battery charging and installation. For your safety, follow
all steps and observe all accompanying safety messages. Section 5 has further general battery maintenance and
recharging instructions you will find helpful.
STEP 1: Activating and
Charging the Battery
Important
The battery was shipped
“dry.” It needs battery elec
trolyte fluid (battery-grade
sulfuric acid) added to it. It
must then be fully charged
with a battery charger before
being used.
Adding electrolyte fluid to the
battery and battery charging can be
dangerous work. The electrolyte
contains acid that can burn or blind
you. Battery charging also pro
duces explosive gases.
To ensure that the battery is
properly activated and charged,
you should review these instruc
tions with your battery technician.
It is strongly recommended
that you have the battery acti
vated and charged by a trained
professional (Troy-Bilt Dealer,
service station, farm equipment
dealer, etc.) if you are not experi
enced with these procedures.
A
DANGER
Battery produces explosive
gases.
• Keep sparks, flames, and
cigarettes away.
• Ventilate area when charg
ing or using battery in an en
closed space.
• Make sure venting path of
battery is always open once
battery is filled with acid.
DANGER
Battery electrolyte fluid is
poisonous and burns severely.
Electrolyte is a sulfuric acid
solution. Avoid spills or con
tact with skin, eyes, clothing.
• To prevent accidents, wear
protective clothes, rubber
gloves and shield eyes with
safety goggles when working
on or near the battery.
• Neutralize acid spills with a
baking soda and water solu
tion. Neutralize electrolyte
container with same solution.
Then rinse with clear water.
Antidote: External- Flush with
water; Eyes- Flush with water
for 15 minutes and get imme
diate medical attention.
Antidote: Internal- Drink large
quantity of water or milk.
Follow with milk of magnesia,
beaten eggs, or vegetable oil.
Call a doctor immediately.

To Activate the Battery:
A
WARNIHG
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
explosion of battery gases.
For shipping purposes only, the
unserviced battery and its hold
down clamp were installed backwards at the factory. When rein
stalling the battery and hold-down
clamp, be sure to turn them around
so they face in the opposite direc
tion from which they were shipped.
A. Use a 7/16" wrench to remove
the two WA” long bolts and the two
1/4" whiz nuts securing the front
and rear hold-down clamp legs to
the battery bracket (Photo 2-23).
Lift off the clamp. Remove battery.
Save the hardware.
B. If there is a short piece of
sealed plastic tubing covering the
vent fitting on the negative side of
the battery (see Photo 2-23), re
move and discard it.
C. Put the battery on a level work
surface, far away from heat- or
flame-producing sources like
stoves, water heaters, dryers, fur
naces, etc.
D. Take off the six filler caps on
top of the battery. Put them aside.
Refer to Photo 2-24.
E. Be sure you are wearing pro
tective clothes, rubber gloves and
eye protection. Fill each cell to the
“Upper Level” line printed on the
battery case using battery-grade
electrolyte solution. (This is 1.265
specific gravity sulfuric acid.)
Temperature of battery and elec
trolyte is ideal when between
bO^^F-to-SO^F. Do not add water or
any other liquid to the battery dur
ing this initial activation.
F. Let battery stand for 30 min
utes. Check electrolyte level in
each cell. Add more electrolyte
solution if needed. Don’t overfill
battery-this could lead to flooding
from the cells during charging.
Photo 2-23:
Remove
hold-down
damp (A).
Remove
the piece
of clear
plastic tub
ing (B)if
so supplied.
Photo 2-24: Remove all six filler
caps (A). Fill each cell up to the
“Upper” level line (B).
To Charge the Battery:
A. Follow one of the three charg
ing methods described next for
maximum starting capacity and
longest battery life.
Note: The electrolyte solution
within the cells is gassing freely
when the surface of the electrolyte
is covered with small bubbles.
When checking for bubbles, al
ways wear safety goggles to pro
tect eyes. A flashlight makes the
inspection easier. Inspect all cells.
17
Our Recommended Method:
Charge the battery at a rate of 1-to2 amperes until all cells gas freely.
Do not exceed 24 hours charging.
First Alternative Chai^g Method:
Charge the battery at a rate of 4-to6 amperes until all cells gas freely.
Do not exceed 8 hours charging.
Page 18
Second Alternative Charging Mdhod:
Charge the battery at a rate from
6-to-12 amperes until all cells gas
freely. Do not exceed 4 hours
charging time.
B. Turn off the charging equip
ment and disconnect the charger
cables from the battery terminals.
C. Recheck electrolyte level in
each cell. Top off any low cells
with electrolyte solution up to the
“Upper” level line.
D. Securely replace all six filler
caps. Use a baking soda and water
mixture to rinse off electrolyte that
may have spilled on the battery.
A DANGER
Never jump start the battery
with a vehicle battery or charg
ing system. This may produce
a battery explosion, causing
acid or electrical burns.
DANGER
To Avoid Personal Injury or
Property Damage;
• Batteries produce explosive
gases - always keep sparks
and flame away from battery.
• Ventilate area when charg
ing or using the battery.
• During charging, don’t
leave battery unattended.
Charging time need not be
continuous.
• Follow safety rules and in
structions 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 could
damage the battery.
DANGER
To Avoid Personal Injury or
Property Damage:
• Do not touch positive bat
tery terminal and any sur
rounding metal objects with
tools, jewelry or other metal
items. Failure to comply
could cause a short circuit
leading to electrical burns or
explosion of battery gases.
• Never bring a gas can near
the positive (+) battery termi
nal. 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.
STEP 2: Connect the Wire
Harness Receptacle
A. The keyswitch (A, Figure 2-25)
is part of the hold-down clamp as
sembly (D). The prongs at the
back of the keyswitch must be se
curely inserted into the plastic wire
harness receptacle (B).
B. Remove the pair of ignition
keys from the keyswitch. Store
them safely away. Do not put a
key in the keyswitch until you have
read the sections in this
Owner/Operator Manual covering
features, controls and operation.
Figure 2-25: First connect Keyswitch (A) to wire harness (B). Then, the acti
vated battery must be secured to mounting platform (C) using the hold
down clamp (D) with its mounting hardware (H, I). Last, install plastic vent
tube (E) over the vent fitting (F), and down into vent tube shield (G).

STEP 3: Installing the Battery
A. Carefully place the activated
battery back on the battery mount
ing platform as seen in Fig. 2-25,
The side of the battery with the
terminals (the posts) and the fill
lines on it must face the rear of
the tiller. [Another way to verify
the correct placement of the bat
tery is when the positive (-I-) bat
tery post is on the left side of the
tiller as you face forward when
standing behind the handlebars.]
A
B. Place the battery hold-down

structions carefully to avoid
damage to your tiller.
clamp (D, Figure 2-25) over the
battery, and secure the two legs of
the clamp to the platform (C) using
the two bolts and whiz nuts (FI, I)
removed previously. Insert the
bolts up from the bottom. Tighten
the hardware to make the battery
secure, but don’t overtighten the
nuts or the clamp tabs will bend.
STEP 4: Installing the
Battery Cables
A. Locate the two (2) 5/8" long
bolts and l/4"-20 hex nuts shown
in Photo 2-3 on page 10. Use them
to connect the loose ends of the
two battery cables to the two bat
tery terminals (posts).
B. On the left side of the tiller (as
viewed from behind the handle
bars), connect the loose end of the
positive (+) battery cable (A,
Figure 2-26 - this is the red cable
already attached at the other end to
the solenoid) to the positive (+)
battery post (B). Flold the cable
terminal against the side of the
post facing the keyswitch. Install
and tighten a bolt (E) and nut (F)
with two wrenches.
C. Slide the pre-installed black
rubber boot (G) completely over
the battery post and hardware.
D. Repeat this procedure on the
right side of the battery. Position
the end of the negative cable (C)
against the negative battery post
(D) as shown, and secure it with
the remaining bolt (E) and nut (F).
Again, slide the black rubber boot
completely over the battery post.
E. Check the lower end of the vent
tube shield into which you inserted
the clear plastic vent tube. The
lower end of the black shield must
be located in front of the wheel
shaft axle. Move it there if neces
sary. Your electric start tiller is
now fully assembled.
C. The clear plastic vent tubing
must be installed next. If coiled
up, straighten it out. Slide one end
of the tube (E, Figure 2-25) over
the vent fitting (F) at the top of the
battery. Slide the other end down
into the black vent tube shield (G).
WARNING
Improper battery venting can
cause a battery to explode,
resulting in severe personal
injury.
Be sure the vent tube is not
crimped, pinched or folded.
Figure 2-26: Connect positive (+) cable (A) to positive battery post (B).
Connect negative (-) cable (C) to negative battery post (D). Be sure to posi
tion bolts (E) and nuts (F) as shown. After the connections are secure, slide

Wheel Speed Lever
Use this lever (C, Fig. 3-1) to select a wheel speed
or the freewheel position. There are three operating
positions; SLOW, FAST and FREEWHEEL.
SLOW - Lever moved all the way down. Use for nor
mal tilling or for low-speed transporting.
FAST - Lever moved all the way up. Use for cultivat
ing or for fast-speed transporting.
FREEWHEEL - Lever in between SLOW and FAST
positions (wheels will roll freely). Use for transporting
the machine on level ground without engine power and
when using stationary PTO attachments.
• To avoid transmission damage, always put the
Wheels/Tines/PTO Drive Lever in NEUTRAL
before shifting the Wheel Speed Lever.
• When shifting into SLOW or FAST, gently roll the

Before operating the tiller, be
sure you have first read and under
stood all Safety Instructions in
Section 1 and Controls information
in Section 3. First practice using
the tiller in an open, level area.
Practice without the tines revolving
- disengage the tines with the
Tines/PTO Clutch Lever. After a
thorough practice session, the tiller
can then be moved to the garden.
WARNING
Your tiller and its optional
PTO attachments are capable
ot causing serious injury to
untrained or careless opera
tors.
To avoid serious personal in
jury or property damage,
read the Owner/Operator
Manual provided with any op
tional accessories or attach
ments before using the tiller
or PTO power unit.
Break-In Operation
During the first few hours of
new tiller operation, the following
maintenance steps are required.
For subsequent maintenance proce
dures, refer to Section 5 —
Maintenance.
1. Change Engine Oil. Change
the oil after the first 5 hours of new
operation. Thereafter, change oil
after every 10 operating hours.
Increase the frequency of oil
changes under very dirty or dusty
conditions.
2. Check Transmission Gear Oil
Level. After the first 2 hours of
new operation, check the gear oil
levels in the PTO power unit and
the tine attachment transmissions.
Thereafter, check them every 30
hours.
3. Check Drive Belt Tension.
Due to belt seating, a tension ad
justment may be needed after the
first 2-to-3 hours of new operation.
Thereafter, check belt tension
every 10 operating hours.
4. Check Hardware, After 2
hours of new operation, check for
loose bolts and nuts. Thereafter,
do this every 10 operating hours.
Preparation Before Starting
Make the following checks and
perform the following services be
fore starting the engine.
1. Check Engine Oil Level.
2. Check the Air Cleaner. It must
be securely assembled and clean.
3. Check Safety Guards. All
guards and covers must be securely
in place.
4. Attach Spark Plug Wire,
5. Check Engine Cooling System.
The cooling fins and air intake
screen must be clear of debris.
6. Adjust Handlebar Height.
7. Check Battery Fluid Level.
Cells must be filled to proper level,
cell caps must be tight, and all
electric wire connections secure.
8. Add Gasoline to Fuel Tank.
Use fresh, clean, lead-free automo
tive gasoline. A minimum of 77
octane is recommended. DO NOT
MIX OIL WITH GASOLINE!
DANGER
Gasoline is highly flammable and its vapors are explosive. Follow
these safety practices to prevent injury from fire or explosion:
• Never fill tank if engine is running or hot from use. Let engine and
muffler cool down before refueling.
• Do not permit open flames, sparks, matches or smoking in the fueling
area.
• Fill fuel tank outdoors in a well-ventilated area. Wipe up any fuel
spills and move tiller away from fumes before starting the engine.
• Use only an approved fuel container and lock it safely away from
children.
• Store fuel and the tiller in a well-ventilated area. Do not store fuel or
tiller where fuel vapors may reach an open flame or spark, or an igni
tion source (a hot water heater, furnace, clothes dryer, electric motor,
or the like).
• Let engine cool before storing.
• Never bring a metal fuel can near battery post on electric start model
tillers. An electrical short circuit could result, causing an explosion of
the gasoline or of battery gases.
Refer to the separate Engine
Owner’s Manual for detailed fuel
recommendation s.
Note: The use of gasoline which
contains alcohol, such as gasohol,
is not recommended. However, if
gasoline with alcohol is used, it
must contain less than 10%
Ethanol and must be removed from
the engine during storage. Do not
use gasoline which contains
Methanol.
Purchase fuel in a quantity that can
be used within 30 days. This will
assure fuel freshness and volatility
tailored to the season. The use of a
fuel stabilizer additive will prevent
gum from forming in the fuel sys
tem or on essential carburetor
parts. See the “Storage
Instructions” in the Engine
Owner’s Manual.
To Add Gasoline:
a. Clean the fuel cap area before
removing the fuel cap.
b. Using a clean funnel, fill tank to
within 1/2" of the top to prevent
spills and to allow for fuel expan
sion. Replace the fuel cap securely
before starting the engine.

Test Operation of Forward
Interlock Safety System
The Forward Interlock Safety
System is designed to shut the
tiller engine off immediately if
you loose control of the tiller and
cannot stop forward motion hy
moving the Wheels/Tines/PTO
Drive Lever into NEUTRAL.
Simply, it is an electrical
grounding system that connects the
two Forward Interlock Levers on
the handlebars to the engine’s igni
tion system. Either one (or both)
of the Forward Interlock Levers
must be kept squeezed against the
handlebar grip(s) whenever the
Wheels/ Tines/ PTO Drive Lever is
engaged in FORWARD.
If you release both the Forward
Interlock Lever(s) before first
moving the Wheels/Tines/PTO
Drive Lever to NEUTRAL, the in
terlock system will ground out the
engine’s ignition system and stop
the engine. (The interlock system
also prevents the engine from start
ing if the Wheels/ Tines/PTO Drive
Lever is engaged in FORWARD.)
This system has an electro-me
chanical design, and so is subject to
normal wear and possible malfunc
tion. As such, it must be checked for
proper operation before you use the
tiller or PTO power unit each time.
How to Check the interlock System:
1. Move tiller outside on level
ground. Remove any obstacles.
2. Check that the Forward Interlock
wire harness plug at the bottom of
the handlebars is firmly connected to
the receptacle on the top, right side
of the transmission. See Photo 4-2.
Photo 4-2: Plug and receptacle of
Forward Interlock Safety System
must be securely connected.
3. Move Wheel Speed Lever to
SLOW position and move Tines/
PTO Clutch Lever to DISENGAGE.
4. Start engine as described later in
this section. Set engine throttle lever
to SLOW, and let engine warm up.
5. Squeeze and holdjust one of the
Forward Interlock Levers against the
handlebar grip while moving the
Wheels/ Tines/ PTO Drive Lever
down to FORWARD. (See Photo
4-3). As the tiller moves forward,
release the 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 squeeze the lever up
against the handlebar grip, and then
return the Wheels/ Tines/ PTO Drive
Lever to NEUTRAL. Repeat this
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 elec
tric start), and do not operate the
tiller or PTO power unit until the
system has been repaired and is
functioning properly.
IMPORTANT - To avoid possible
damage to the Forward Interlock
Safety system, do not use highpressure sprays near the wire har
ness receptacle or neutral plunger
assembly.
A
DANGER
The Forward Interlock Safety
System is designed for the
operator’s satety. Do not dis
connect or attempt to defeat
the purpose of the system. If
the system malfunctions, im
mediately contact your 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 Satety
System is functioning prop
erly. Always test the system
before using the tiller or PTO
power unit.

Starting and Stopping
the Engine
IMPORTANT- Use the following
steps to practice starting and
stopping the engine ONLY. Do
not attempt to drive tiller or
PTO Power Unit until you have
read all operating instructions in
this Owner/Operator Manual.
To Start the Engine:
1. With the engine off, place the
Wheels/Tines/PTO Drive Lever in
the NEUTRAL position (see
Figure 4-4). If in the FORWARD
position, tap or lift the lever up and
then release it to obtain NEUTRAL.
2. Lower the Depth Regulator
Lever (see Figure 4-4) until the
tines are off the ground.
3. Move the Wheel Speed Lever
(Figure 4-4) to either the SLOW or
FAST position. Be sure to roll the
wheels while shifting the lever until
the wheels are engaged.
Note: If using a PTO stationary at
tachment, move lever to FREE
WHEEL and block the wheels to
prevent the equipment from moving.
4. Put the Tines/PTO Clutch Lever in
the DISENGAGE position (see
Figure 4-4). (Use the ENGAGE po
sition if you want the tines to revolve
or to apply power to a PTO-driven
stationary attachment.)
5. The fuel tank shutoff valve must
be in the OPEN position (see Figure
3-7, Page 23).
6. Move the Engine Throttle Lever
on the handlebars forward (away
from the STOP position). On the
8HP and lOHP engines, the Throttle
Control Lever at the front of the en
gine will also move.
7. On the 8HP and lOHP engines,
put the ON/OFF switch on the top of
the engine in the ON position.
8. On the 7HP engine, move the
Choke Control Lever down to the
CHOKE position (see Fig. 4-5). On
the 8HP and lOHP engines, put the
Choke Control Lever in the CHOKE
position (see Fig. 4-6). Note: Use of
the CHOKE position may not be nec
essary if the engine is still warm from
recent operation.
9. For recoil start engines;
a.) Stabilize the tiller by placing
one hand on the fuel tank.
b.) Check that area behind you is
free of persons or obstacles. Use
your other hand to slowly pull out
the start rope until resistance is
felt. Then rapidly pull the rope
out to start the engine. Let it
rewind slowly.
10. For electric start engines:
a. ) Turn key to START position.
Do not hold key at START for
more than a few seconds. Starter
damage can occur if it is cranked
more than 15 seconds per minute.
b. ) Release key when engine
starts. It will move to RUN posi
tion automatically.
11. If engine does not start after
several tries, repeat start attempts
with the choke opened slightly.
12. After the engine starts, slowly
move the Choke Control Lever to a
halfway position, then to the RUN
position (lever fully opposite the
CHOKE position). DO NOT oper
ate the engine with the lever in a
partial CHOKE position as exces
sive speeds may occur.
13. Move the Throttle Lever to the
SLOW position and allow the en
gine to warm up.
27
Page 28
To Stop the Engine:
1. To stop the wheels and tines,
move the Wheel s/Tines/PTO Drive
Lever to the NEUTRAL position
and then release both Forward
Interlock Levers.
Starting the Electric Start Engine
with the Recoil Starter Rope
If necessary, an electric start en
gine may be started with the recoil
start rope. Before doing so, follow
the procedure below applying to you.
Figure 4-5: Choke Control Lever on
the 7HP engine. Down for CHOKE;
up for RUN.
Figure 4-6: Choke Control Lever on
8HP and 10HP engines. Left for
CHOKE; right for RUN.
2. Move the engine Throttle Lever
to the STOP position (and on elec
tric start models turn the key to
OFF). Remove the key for safe
keeping.
Note: The 8HP and lOHP engines
have a Throttle Control Lever and
an ON/OFF switch on the engine.
Either control can also be used to
stop the engine. On electric start
models, always remove the key for
safekeeping.
IMPORTANT - If the engine
does not stop after moving the en
gine controls to STOP or turning
the keyswitch to OFF, then stop
the engine by moving the Choke
Control Lever to the CHOKE
position. This will stall the en
gine. Use this procedure only in
an emergency! Repair the engine
control or keyswitch before reusing
the tiller.
1. If battery condition is OK (not
“dead” or damaged), leave it con
nected on the tiller so it gets
recharged during engine operation.
Be sure battery cells are full and
cables are connected before start
ing the engine.
2. If battery is “dead” or dam
aged, disconnect and remove it for
testing by a qualified mechanic.
Before starting engine, wrap metal
terminal at end of positive cable
with electrical tape and secure the
cable to the battery bracket to pre
vent electrical sparking.
3. Before starting the engine with
the recoil start rope, turn the
keyswitch to the RUN position.
The Throttle Lever must be in the
START position and the choke
lever in the CHOKE position.
OCold Weather Operation
Below dO'^F, take the following steps to protect
your engine and transmission from damage:
1. Refer to the Engine Owner Manual provided with
your unit for motor oil specifica
tions appropriate for cold
weather operation.
2. Let engine warm up before
putting it under a load.
3. Use winter-blend gasoline.
4. Use the correct weight gear oil in
PTO Power Unit transmission.
5. Warm up the transmission gear oil as follows: with
engine running, move Wheel Speed Lever (see Figure
4-4) to FREEWHEEL
(then block wheels so
they can’t roll), put
Tines/PTO Clutch
Lever in DISEN
GAGE, then squeeze
one of the Forward
Interlock Levers and
shift the Wheels/
Tines/PTO Drive Lever
to FORWARD.
6. If wheels are frozen to
the ground, melt ice with warm water.

To Operate the Tiller
CAUTION
To avoid serious personal injury or
damage to equipment:
• Always place Wheels/Tines/PTO
Drive Lever in NEUTRAL before
starting engine, and before en
gaging wheels, tines or other PTOdriven attachments.
• Be sure there are no obstacles
behind you before reversing.
• Wheels/Tines/PTO Drive Lever
should automatically return to NEU
TRAL when released from RE
VERSE position. If it does not,
move lever to NEUTRAL manually
and see Section 5 to adjust it.
• No reverse motion should occur
if Wheels/Tines/PTO Drive Lever
is not held up in REVERSE. See
Section 5 for adjustment steps. Do
not use tiller unless properly ad
justed.
• Always return to NEUTRAL and let
all motion stop before shifting to
FORWARD or REVERSE.
When first practicing, keep the
Tines/PTO Clutch Lever in DIS
ENGAGE position and the Wheel
Speed Lever in SLOW position.
To Begin Tilling:
1. Start the engine (see previous
instructions). The Wheels/Tines/
PTO Drive Lever must be in NEU
TRAL before starting the engine.
The Wheel Speed Lever must be in
either SLOW or EAST position.
2. Test the Forward Interlock
Safety System. See page 26.
3. Set Depth Regulator Lever to
desired depth and increase engine
speed. (When “practicing”, keep
tines in the “Travel” position.)
4. Move Tines/PTO Clutch Lever
to ENGAGE position (if practic
ing, leave in DISENGAGE).
IMPORTANT - Do not move
Tines/PTO Clutch Lever to EN
GAGE unless Wheels/Tines/PTO
Drive Lever is in NEUTRAL.
Tiller damage may occur!
5. For forward motion of wheels
and tines, squeeze and hold either
or both Forward Interlock Levers
(see Photo 4-7) against the handle
bar grip, then move the Wheels/
Tines/ PTO Drive Lever down to
FORWARD position.
6. When the tiller moves forward,
relax and let the wheels power the
tiller along while the tines dig.
Walk behind and a little to one side
of the tiller (on the side that is not
yet tilled - see Photo 4-8). Use a
firm grip with one hand on the han
dlebars, but keep your arm loose.
IMPORTANT- Let the tiller
move ahead at its own pace. Do
not push it ahead—this reduces
operator control. Do not push
handlebars down attempting
deeper digging— this takes
weight off the wheels, cuts trac
tion, and causes the tines to try to
propel the tiller.
WARNING
To avoid injury, keep hands,
feet, legs, and clothing away
from revolving tines.

Operation
7. To stop forward motion: tap or
lift Wheels/Tines/PTO Drive Lever
up to NEUTRAL and let go of the
Forward Interlock Levers. The
wheels and tines will stop and the en
gine will continue running.
8. In an emergency, stop all for
ward motion by letting go of all
handlebar control levers- this
shuts off the engine too.
9. For reverse motion:
a. Do not till while in RE
VERSE.
b. Put TinesAVheels/PTO Drive
Lever in NEUTRAL and re
duce engine throttle speed.
Verify that the area behind
you is clear.
Turning Around
Turning the tiller around is easy
and just requires practice. First
find the balance point between the
engine and the tines by lifting up
the handlebars. Once you have
found the balance point, then let
the powered wheels do the “turn
ing” as you push sideways on the
handlebars in the direction of the
turn. Practice the turning maneu
ver described here in a large open
area. Once comfortable turning
the tiller, you can then take it to the
garden area. See Photo 4-9 below.
c. Move Wheel Speed Lever to
the SLOW position.
d. Move the Tines/PTO Clutch
Lever to DISENGAGE.
e. Lift up handlebars until tines
are off the ground, then
move (and hold) Wheels/
Tines/PTO Drive Lever all
the way up. The Forward
Interlock Levers do not need
to be squeezed to use reverse.
10. To stop reverse motion:
Release the Wheels/Tines/PTO
Drive Lever- it automatically re
turns to the NEUTRAL position.
This stops the wheels immediately.
(The Forward Interlock Levers will
not stop REVERSE motion.)
away from the tines (which should
be disengaged). Let the powered
wheels do the hard work. The in
side wheel will pivot in place while
the outside wheel drives the tiller
around in the direction of the turn.
Refer to Photo 4-9.
Note: Use REVERSE if necessary
to turn in a limited space.
4. When the turn is complete, shift
to NEUTRAL and lower the han
To Stop the Engine
Move the engine throttle lever to
the STOP position (and turn key to
OFF on electric start models).
Remove the key for safekeeping.
A
CAUTION
To Help Avoid Personal Injury
or Damage to Equipment;
• Be sure no obstacles are
behind you before operating
the 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
used to reversing.
dlebars. Move Tines/PTO Clutch
Lever back to ENGAGE position
and resume forward operation.
WARNING
To help avoid personal injury
from revolving tines, always
put the Tines/PTO Clutch
Lever in DISENGAGE before
turning tiller around.
Turning Procedure:
1. At the end of a row, move the
Wheels/Tines/PTO Drive Lever to
NEUTRAL position and reduce
the engine speed.
2. Move the Tines/PTO Clutch
Lever to DISENGAGE position.
3. Resume forward operation, and
lift handlebars until tines are above
the ground. Find the balance point
between the engine and the tines.
Then PUSH the handlebars to
swing the tiller around. Be very
careful to keep your feet and legs

Transporting Your Tiller
The tiller’s powered wheels
make moving the tiller to and from
the garden easy when the engine is
running. If the engine is off, you
can also roll the tiller to another lo
cation if the Wheel Speed Lever is
in the FREEWHEEL position.
WARNING
To help avoid personal injury
from revolving tines, always
move Tines/PTO Clutch Lever
to DISENGAGE position be
fore transporting, loading or
unloading tiller.
To Transport The Tiller Around
Your Property;
1. Place the Tines/PTO Clutch
Lever in DISENGAGE position.
2. Move Depth Regulator Lever
down all the way (TRAVEL setting).
3. If using engine power, move
Wheel Speed Lever to either
SLOW or FAST, and use the
Wheels/Tines/PTO Drive Lever to
drive the wheels.
4. If the engine is stopped, move
Wheel Speed Lever to FREE
WHEEL, and manually push tiller.
To Load Or Unload The 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 lbs.
2. Move the Tines/PTO Clutch
Lever to DISENGAGE position.
3. Move Wheel Speed Lever to
SLOW position and reduce the en
gine throttle speed.
4. To go up ramps, use FOR
WARD drive and follow the tiller
up the ramps (Figure 4-10).
5. To go down ramps, use RE
VERSE drive and back down the
ramps. Never go down the ramps
in FORWARD drive since the
tiller could tip forward, exposing
you to the tines (which should be
disengaged as we’ve recom
mended). See Figure 4-11.
31
Page 32
To Change Belt Speeds
Your tiller has two belt-driven
speed ranges - HIGH RANGE and
LOW RANGE - you pick one or
the other by deciding which set of
pulley grooves you move the for
ward belt into. By moving the belt
from one speed range into the
other, in combination with the
FAST and SLOW wheel speeds of
fered by the Wheel Speed Lever,
you obtain a choice of four differ
ent forward wheel speeds and two
different tine speeds.
Changing the belt from LOW
range into HIGH range (or back
again) is simply a matter of mov
ing the belt from one set of
grooves on the engine and trans
mission pulleys to a second set of
grooves. This change is done
quickly without tools. See Photos
4-12 through 4-16 for reference.
By using the two belt speed
ranges with the two Wheel Speed
Lever positions (FAST and SLOW),
here are the wheel speeds / tine
speeds available to you:
At 3000 RPM engine speed, the wheel
and tine speeds you can choose from
are:

When the tiller is moving in
REVERSE, the wheels and tines
are powered by the rubber reverse
disc and not by the belt. So you
have only two reverse speeds as
determined by the SLOW and
FAST positions of the Wheel
Speed Lever.
IMPORTANT: Proper belt ten
sion is important to good perfor
mance. Check tension after first
2 hours of new operation; then
every 10 operating hours.
Photo 4-12: Belt range positions.
To Change From LOW Range
to HIGH Range
1. To avoid personal injury, shut
off engine, let all moving parts
come to a complete stop, then dis
connect the spark plug wire and
move it away from the spark plug
before making any adjustments.
2. Place Wheels/Tines/PTO Drive
Lever in NEUTRAL.
3. Kneel on left sideof 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
into the forward groove of the
transmission (lower) pulley. See
Photo 4-13. Now go to the other
side of the tiller- finish seating the
belt in the forward groove.
4. On the left sideof the tiller,
work the belt as much as possible
into the forward groove in the en
gine (top) pulley. See Photo 4-14.
Finish seating it 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, creating the slack.
5. Check both sides of the pulleys
to see the belt is seated in HIGH
range grooves of each pulley.
WARNING
To help avoid seri
ous personal in
jury, stop the en
gine, remove the
ignition key, dis
connect spark plug
wire and move the
wire away Irom
the spark plug,
and let engine and
muffler cool down
before changing
belf speeds.

transmission pulley (lower pulley)
over into its rear pulley groove.
5. Check that the belt is fully
seated in the pulley grooves. Look
at this from both sides of the tiller.
Choosing Tiller Wheel
and Tine Speeds
Your tiller offers four wheel/tine
speed combinations to handle ev
ery tilling task and garden job. By
experimenting, you’ll find the right
tilling depth, engine speed, and
wheel and tine speed combination
that is best for the soil in your gar
den. Here’s how to approach jobs:
WHEEL SPEED AND BELT RANGE SELECTION GUIDE
IMPORTANT — For correct wheel speed and belt range choices when using attachments or accessories
other than tines, read the Owner/Operator Manual provided with the attachment or accessory.
SLOW GEAR, LOW BELT RANGE
Till in sod.
Till in hard clay.
Till under standing cornstalks
in tough soil conditions.
Till under cover crops.
Prepare a deep seedbed.
Till in stony soil.
Till in residues and organic
matter.
Mix in fertilizers, manure.
SLOW GEAR, HIGH BELT RANGE
Till in sod or hard clay.
Till under standing cornstalks
(slow, steady speed allows
time to shred stalks).
Till under cover crops (best
wheel speed and belt speed
range in most soils).
Prepare seedbeds (best speed
choice in most soils).
Till in stony ground.
Build raised garden beds.
Mix in fertilizer.
Use hiller wings in hard soil.
Mix fertilizer and manure.
Till residues, organic matter.
1. Advance the throttle lever so
the engine has sufficient power.
2. Do not set the depth regulator at
too deep a setting to avoid having
the engine labor or the tiller buck.
3. Your settings are “ideal” when
the tines are breaking up the soil
nicely, the engine is not laboring,
and your progress is steady and
smooth. See the Selection Guide
below for hints.
FAST GEAR, LOW BELT RANGE
Go over seedbed for the last
time before planting crops.
Cover over seeds in wide row
or plot planting (raise han
dlebars to avoid going too
deep).
Best for hilling and furrowing.
Best for making raised beds.
Cultivate (raise handlebars to
avoid going too deep).
Good for tiliing large areas.
Till organic matter in.
Cultivating between raised
beds with hiller-furrower at
tachment.
WARNING
The HIGH speed belt range
position combined with a
FAST wheel speed setting
propels the tiller at the
fastest pace. To help avoid
personai injury or property

FAST GEAR, HIGH BELT RANGE
Prepare seedbeds for planting.
Cover seeds with less need to
hold up the handlebars.
Cultivate (tiller travels faster,
rides higher on the soil; al
lows engine RPM to be re
duced; handlebars don’t
have to be raised).
Keep large areas tilled and
cultivated in the summer.
Till under organic matter.
Move tiller location quickly.
Cultivate between raised beds

TILLING IN THE GARDEN
Here are tips and suggestions to
help you get the most satisfaction
and performance from your tiller.
Tilling Depths
When you begin tilling in the
garden, please go slowly and easily
at first. It’s very important that
you not try to dig too deeply too
quickly. Soil that hasn’t been tilled
for some time must be tilled up
gradually— it’s almost impossible
to dig down 4"-to-5" on the first
pass with the tiller in compact soil.
IMPORTANT — Start tilling at
a very shallow depth regulator
setting, only 1" or 2" deep the
first time through the garden
area.
With each succeeding pass, you
can adjust the depth regulator lever
upward so the tines will dig an
other inch or two deeper. Hint -
water your garden area a few days
before tilling to make the job much
easier. If it is difficult to dig down
really deep, let the newly-worked
soil “rest” for a day or two. It will
then be easier to till.
Don’t till when the soil is too
wet. Wet soil will leave large
clumps after tilling - and will only
harden later. Hint - test the soil by
squeezing it — if it compresses too
easily it’s too wet to till.
Seedbed Preparation
In a well-prepared seedbed, the
soil will be loose and fine-textured.
Try to till the first time a few
weeks before the planting date; till
the second time a few days later;
then till the third time on the day
of planting. This will make the
seedbed as loose and well-aerated
as possible.
When preparing the soil, go
down the same path twice in the
first row, then overlap each suc
ceeding row by one-half the tiller’s
width. See Figure 4-18. Next,
make a second pass through the
seedbed at a right-angle to your
earlier rows (refer to Figure 4-19).
Again, overlap each row by onehalf the width of the tiller. (In very
hard ground, several passes over
the seedbed may be needed.)
If there is not enough room to
make a second pass at a right-angle,
go back and repeat the first pass,
overlapping the rows by one-quar
ter the width of the tiller.
Plan to expand your garden the
following year? Bust up the sod in
the Fall - the ground will be com
pletely broken down when Spring
arrives. You can also plant a cover
crop in the Fall in that newly tilled
area - the cover crop will keep the
soil intact and enrichen it.
WARNING
To help avoid personal injury, be
aware that the filler can unexpect
edly bounce up or jump ahead and
be propelled away trom 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 control of the tiller;
• Walk behind and to the side of the
tiller. Use one hand on the han
dlebars, relaxing your arm but with
a secure hand grip.
• Use shallow depth regulator set
tings. Till gradually deeper.
• Use slower wheel, tine and en
gine speeds.
• Clear the tilling area of all large
stones, roots and other debris.
• Do not put downward pressure
on the handlebars. If needed,
apply slight upward handlebar
pressure to keep the tines from
digging too deeply.
• Avoid contacting hard soil or sod
at the end of a row - reduce engine
speed and lift handlebars to raise
tines out of the soil.
• In An Emergency, stop tines and
wheels by moving Wheels/Tines/
pro Drive Lever to NEUTRAL. If
you cannot reach the lever or have
lost control. Let Go Of The Han
dlebars and All Controls.

ulator settings when tilling at first.

overlap half of the previous row.

one direction. Then at a 90° angle.

Avoid Making Footprints
When making final tilling or cultivating passes
through the garden, try to walk on the side of the tiller
where you will be on as-yet unfilled soil. Don’t leave
footprints as shown in Photo 4-20.
Eliminating footprints means more than just a good
appearance in your garden. The lack of footprints
aids in preventing soil erosion and keeps weed seeds
from being “replanted” in the newly tilled soil. Soil
that hasn’t been compacted by footprints is also easier
for plant roots to grow in.
Cultivating
If you plan carefully before planting, you can leave
enough room between plant rows for later cultivating
with the tiller. That will eliminate hand-weeding or
hoeing chores during the growing season!
The tiller hood is 22-'A" across. Allow for that
width between rows plus additional room for plant
growth (particularly bushy crops like beans, tomatoes,
peas, etc.) See Figure 4-21.
Photo 4-20: Avoid leaving footprints.
Power Composting
For a garden to be bountiful, the soil must be re
plenished regularly. Harvested produce removes ni
trogen, phosphorous, and potassium from the soil —
these plant nutrients must be replaced.
An easy and effective way to do this is to use your
tiller to chop, blend, and turn under all kinds of or
ganic matter (crop residues, leaves, grass clippings,
etc.). This material decomposes during the off-season
and releases nutrients into the soil. See Photo 4-22.
When power composting with your tiller, adjust the
depth regulator to the deepest setting possible (move
it up so one of the bottommost notches is engaged)
without causing the engine to labor or the tiller to jump
ahead. Till under crop residues as soon as possible
after crop harvesting, as they’ll till under more easily
when green. Use the HIGH belt range and SLOW
Wheel Speed Lever position when power composting.
If necessary, move the belt to LOW range to slow
down the tine speed.
Figure 4-21: Allow sufficient mam between rows
far cultivating.
Last, plant a cover crop to protect the soil during the
non-growing season. Then, in the Spring, the cover
crop can be tilled under a few weeks prior to planting,
providing more organic matter to help feed the soil.
Photo 4-22: After harvesting produce, till under
crop residues to add nutrients to the soil.

SPECIAL TROY-BILT GARDENING TECHNIQUE— Till Under Standing Cornstalks
After com is harvested, the
stalks should be tilled into the soil
while still green. If you wait until
they’ve dried out, they’ll be harder
to till under, and the roots will
break loose from the soil which
you don’t want! (Don’tpull the
roots out by hand or cut the stalks
before tilling — it is only when the
stalks are still firmly anchored by
their roots that the chopping and
cutting action of the tines gets a
chance to work best.)

First Pass Till along first

stalks.
Three Rules For Tilling Under
Cornstalks
Knocking down cornstalks and
tilling them into the soil is not hard
to do if you understand three basic
principles: First - As you move
forward into a row of stalks, aim
the tiller so the stalks go between
the left wheel and the transmission
case (see Photo 4-24). Don’t use
the right wheel because damage
could occur to the air cleaner, car
buretor or throttle linkage.
Second- Each new pass should
overlap the previous pass by onehalf the width of the tiller.
Third - Till as deeply as possible.
Pull the Depth Regulator all the
way UP and engage the lowest
notch for deep tilling. Use either
LOW or HIGH belt range and
SLOW wheel speed gear position.
Note: Depending upon the size
and height of the stalks, you may
be able to use LOW belt range and
PAST wheel speed gear.
Let the tilled in stalks decom
pose for a week or so. Then till in
the remaining residue as deep as
possible. Again, overlap your till
ing passes so everything gets thor
oughly processed. After another
week, sow a cover crop, like an
nual rye grass.

Clearing Debris From The Tines
The Bolo Tines have a self
cleaning action which reduces
most vegetation tangling in the
tines. However, grass, string, or
tough vines can get tangled. It’s
not necessary to remove all the
material, but you should get
enough out so the action of the
tines isn’t impaired.
To avoid tangling:
• Set depth regulator lever for deep
tilling- this results in maximum
chopping action.
• Till under crop residues or cover
crops while still green.
• Sway handlebars from side to
side (6"-to-12" either way) when
power composting - this can clear
tangled tines.
If tangling occurs, stop the engine,
disconnect the spark plug wire, let
all moving parts stop, then use a
pocket knife or linoleum knife to
clear away the tangled materials.
WARNING
To help avoid personal injury,
stop the engine, remove the
electric start key, then dis
connect the spark plug wire
and move the wire away from
the spark plug hetore at
tempting to clean the tiller
tines by hand.
Tilling Up And Down Slopes
Planting space may be so lim
ited that you only have sloped
ground available for your garden.
If so, please follow two very im
portant guidelines for tilling on
slopes: 1) till only on moderate
slopes, never on steep ground
where footing is difficult; 2) we
recommend you plant rows up and
down the slope (rather than terrac
ing crossways) to get more plant
ing room and also sufficient room
for cultivating. See Photo 4-27.
Growing a garden vertically on
a slope doesn’t have to mean soil
erosion will be a major problem.
You just need to put in enough or
ganic matter so the soil has good
moisture-holding ability, and you
need to avoid making footprints or
leaving wheel marks. This keeps
erosion to a minimum.
CAUTION
TO AVOID SERIOUS PERSONAL INJURY OR DAMAGE TO 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 tootwear that increases
stability and reduces slippage.
• Do not use FAST wheel speed
position when on sloped ground.
• 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 lu
brication), be sure the correct oii
level is maintained during all uphill/downhill tilling operations.
Check the level of the oil in your
engine after every one-half hour
of operation.
When tilling vertically on a
slope, try to make the first pass in
an uphill direction. The tines will
dig more deeply than when going
downhill. You may have to lift the
handlebars slightly going uphill.
When tilling down the slope, over
lap the previous uphill pass by half
a tiller width. Hint: for best re
sults, use the HIGH belt range and
SLOW wheel speed lever position.
Photo 4-27: Tilling on a moderate slope. (Don’t till on
steep ground.)
37
Page 38
Terrace Gardening
If a slope is too steep or not
long enough for vertical tilling, it
may be necessary to till across the
slope and create terraced rows.
Terraces are rows that are cut into
the side of a slope, creating a nar
row, but flat area on which to
plant. On a long slope, you can
make several terraces, one below
the other on the slope.
IMPORTANT: Do not till across
a slope without creating terraces.
Simply tilling across the slope
and leaving unterraced rows on
the slope creates hazardous foot
ing for you, and invites soil ero
sion. When you will be making
rows across a slope, be sure they
are terraced rows.
Terraces should be made about
two-to-three feet wide. This will
allow one or two rows of plants on
the terrace, and allow enough room
to till under crop residues.
However, with a terrace this wide
there may not he enough room for
cultivating. Hint: If you make ter
races too wide, you ’ll be digging
far into the hillside, exposing poor
subsoil in which plants will not be
their most productive.
Move the belt into LOW belt
range and the Wheel Speed Gear
Lever to SLOW position. Start to
terrace at the top of the slope. Go
all the way across the slope several
times until the first terrace is made.
See Figure 4-28 and Photo 4-29.
As you work down the slope, al
ways keep the uphill wheel in the
soft, newly tilled soil. Each suc
ceeding terraced area is started by
walking below the terrace you are
preparing. In four or five passes,
the tiller can carve out a flat and
wide enough terrace for planting.
Don’t till the last 12-inches
(leave at least that much soil un
tilled ) of the downhill outside
edge of each terrace. Keeping this
strip untilled helps prevents your
terraces from breaking apart and
washing downhill. This untilled
strip also gives you a walking path
between terraces.

Tilling Across Slopes Without Terraces
Tilling across a slope without forming terraces is
not recommended. Of course it can he done, but do
study your terrain carefully and try to avoid going
across a slope without making terraces. See if it isn’t
possible to till vertically up and down the slope or, as
a second option, to create terraces.
making unterraced passes across the slope by starting
at the very top of the slope. Make your second pass
by overlapping half the width of the first pass.
Always keep the uphill wheel in the soft, newly tilled
soil. This will increase the stability of the tiller. For
best results, move the belt into LOW belt range and
the Wheel Speed Gear Lever into the SLOW position.

or 5 passes with the tiller.
Soil Enrichment Idea
Trench Composting — Trench
composting is easy with the op
tional Hiiler-Furrower Attach
ment (see Section 5). Just dig a
trench, put in all kinds of or
ganic matter, and cover with
soil. Earthworms and microbes
will break it down quickly.
Again, you should make certain that the slope is
not too steep to till on at all. If it’s safe, you can begin

SPECIAL TROY<BILT GARDENING lECHUmE— Making Raised Beds For Planting
If you have wet soil or heavy
clay soil, most crops won’t grow
well due to a lack of air and nutri
ents. Raised beds can help solve
these problems. In addition, they
provide a good irrigation system,
give more sun to the plants, and
foster good root growth. Raised
beds are easily made too with the
optional Hiller-Furrower attach
ment.
You can even try wide-row
planting on raised beds. Wide
rows can be spaced from 30 inches
to 36 inches apart, and from 8
inches to 10 inches high.
Photos 4-30 through 4-33 at
right show you the steps to take to
create raised beds. After working
the soil to a fine seedbed, attach
your Hiller-Furrower and use it to
make your rows. The hiller wings
will raise up the soil, creating the
foundation for the raised beds.
After you plant seeds on the ridges
of each row, rake the ridges flat.
Then use the tiller with the furrower to make irrigation trenches
at the end of each row.
Photo 4-30: Step 1 — Work soil to a
deep, smooth, loose seedbed.
Photo 4-32: Step 3 — After planting
seeds on the ridges, rake loose soil
over the top. Firm the soil per seed
directions.

Photo 4-33: Step 4 — Use furrower

SPECIAL TROY-BILT GARDENING TECHNIQUE—
Wide-row planting is a very productive gardening
technique we suggest you tiy. As the name implies,
seeds are broadcast in bands anywhere from 10 inches
to 2 feet wide or more, rather than in traditional, nar
row single rows. As a result, you’ll typically grow
anywhere from 3 to 4 times (or more) produce in the
same space normally set aside for an area that has nar
row, single rows.
Wide-row planting (see photos at right) automati
cally 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 seedbed and mark off the rows
with string, just hand-broadcast the seeds as seeding a
lawn (not quite as much as lawn seed). Cover with
soil and tamp the area firmly with a hoe.

THE PTO POWER UNIT
As explained on Page 2 of this
Manual, your tiller is really a selfcontained PTO power unit that was
shipped to you with a tine attach
ment connected to it. The tine at
tachment is quickly removed and
replaced by other attachments that
are available from us. The instruc
tions given here will familiarize
you with your PTO Power Unit.
Please read these pages carefully.
VERY IMPORTANT
Before operating your PTO Power
Unit tor the tirst time, make sure
that you have:
• Read all the safety instructions
in Section 1 of this Manual and in
the Manual supplied with any at
tachment.
• Read the controls information
and operating procedures tor the
tiller and engine described in
Sections 3 and 4 ot this Owner/
Operator Manual.
• Reacf anct understand the assem
bly instructions, controls informa
tion, arrd operating procedures for
the attachment as described in the
Owner/Operator Manual that is
supplied with the attachment.
Removing And Replacing The Tine Attachment
The following steps explain how
to remove and replace the tine at
tachment. The only tool you will
need is a 3/4" wrench (minimum
12" long for good leverage).
There are two optional acces
sories that make the following
steps easier. The Kickstand acces
sory prevents the PTO Power Unit
(engine end) from falling forward
when an attachment is removed
(Photo 4-37). The Tine Attach
ment Cradle accessory gives you a
handy support in which to rest the
tine attachment when it is removed
from the tiller (see Photo 4-38).
For more information about other
accessories, refer to “Accessories”
at the back of this Manual.
^ CAUTION
TO AVOID PERSONAL INJURY
OR DAMAGE TO EQUIPMENT:
• Stop the engine, remove
the electric start key, discon
nect the spark plug wire and
let the engine and muffler
cool before removing or in
stalling any attachment.
• Do not place hands, tools,
or any object near or inside
the PTO access hole when
the engine is running.
• When removing or replac
ing the tine attachment, be
careful of the sharp edges on
the tiller hood. Wear thick
gloves for hand protection.
• When the tine attachment is
removed, always place it in
the Tine Cradle or prop it up
to prevent the attachment
from tailing torward.

TIGHTEN BOLTS AND NUTS
^WARNING
To help avoid personal injury,
stop the engine, remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the spark
plug, and let the engine muf
fler cool before inspecting or
servicing the tiller or engine.
Check for loose or missing
hardware every ten (10) operating
hours. Failure to tighten or replace
fasteners can cause poor perfor
mance, equipment damage or oil
leakage. See your Parts Catalog
for complete fastener descriptions.
Most hardware on your tiller is
visible. Pay particular attention to
hardware shown in Photos 5-1, 5-2,
5-3, and Figure 5-3A.
1. Check the transmission pulley
mounting bolt (Photo 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 “freezes” the pulley
while you tighten the bolt.
2. Check jam nut on left side of
neutral plunger assembly (Photo 5-
2). If loose, immobilize bolt head
with one wrench and use another
wrench to tighten the nut.
3. Check the three rear bearing
cap screws under the depth regula
tor mounting bracket (“A”, Photo
5-3). If any is loose, it can cause
an oil leak or drive shaft end play.
4. Check the five bolts securing
the tiller housing cover to the left
side of the transmission (“B” in
Photo 5-3). Gear oil can leak from
a loose housing cover. To reach
the bolts, remove the left side tine
holder. See “Bolo Tine
Maintenance” in this Section for
tine holder removal directions.
5. Check both swing-bolts (“C”,
Photo 5-3) that connect the power
unit transmission to the tine attach
ment. Both bolts should be
checked every 2-1/2 hours of oper
ation. If loose, wear can occur on
the locating pin on the power unit,
and cause enlargement of the locat
ing hole in the tine attachment.
Using a torque wrench, tighten
these bolts to 70-to-80 ft.-lbs.
6. Check the locknut that fastens
the shifting linkage to the eccentric
shifting lever (“D”, Photo 5-3). Do
not tighten the locknut against the
eccentric lever. It should be very
close to, but not touching the lever.
7. Check the four bolts and nuts
securing left and right tine holders
to the tine shaft (Figure 5-3A).
IMPORTANT- Give screws or
bolts that go into the transmis
sion housing a coating of non
hardening gasket sealant to pre
vent gear oil from leaking.

WARNING
To help avoid personal injury,
stop the engine, remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the spark
plug, and let the engine and
muffler cool before inspect
ing or lubricating the tiller.
Lubricate the numbered areas in
Photos 5-4 and 5-5, as follows:
1. Oil the wheel shaft between the
wheel hubs and the transmission
housing (Photo 5-4).
2. Oil all pivoting and connecting
points on the Wheels/Tines/PTO
Drive Lever and the Wheel Speed
Lever (Photo 5-4). If Wheel Speed
Proper lubrication of the tiller’s
mechanical parts is an essential
part of good maintenance. Lubri
cation 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 grease
with 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
Lever has a grease fitting on pivot
assembly, apply 2-to-3 strokes of
multi-purpose grease at beginning
and end of tilling season.

TRANSMISSION GEAR OIL
MAINTENANCE
WARNING
To help avoid personal injury,
stop the engine, remove the
electric start key, disconnect
the spark plug wire and move
it away from the spark plug,
and let the engine and muf
fler cool before inspecting or
servicing the tiller.
A. Checking for Oil Leaks
At 25-hour operation intervals,
check the tiller for oil leaks. In
spect for oil accumulations on the
tiller or the floor where it’s stored.
A small amount of oil seepage
or 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.
It may be impossible to deter
mine how much oil has been lost,
so check the oil levels in the PTO
transmission and the tine attach
ment before using the tiller again.
Add any necessary gear oil.
Serious damage to the transmission
components can result from opera
tion when gear oil levels are low.
If tilling during very hot
weather, the gear oil may heat up
and expand inside the transmis
sions. To allow for this oil expan
sion, both the power unit transmis
sion and the tine attachment trans
missions have oil relief vents (see
Figure 5-6).
Photo 5-5: Use grease liberally in PTO access hole.
46
Page 47
The vents allow small amounts of
oil to seep out.
If a serious leak is discovered,
please contact our Technical
Service Department for parts and
service advice.
B. 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. Op
erating them while low on gear oil
(even briefly) can cause serious
damage to internal components.
Preparation:
1. The transmissions must be
cool, since hot gear oil expands
and gives a false reading.
2. The power unit transmission
and the tine attachment transmis
sion must be connected when
checking (or adding) gear oil.
To Check the Power Unit Oii Levei:
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
(refer to Figure 5-7).
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 “C. Adding or
Changing Gear Oil.”
To Check the Tine
Attachment Oil Level:
Two different gear oil check
ing procedures for the tine at
tachment transmission are de
scribed next. Use the first proce
dure 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 dip
stick from the tine attachment
transmission (Figure 5-8) to see
which type dipstick you have.
Then replace the dipstick.
For Dipsticks With ‘Check Cold’ Marking:
1. Put the tiller on level ground.
2. Pull the Depth Regulator Lever
back, then push it down all the way
(to engage its top notch). This lifts
the tines off the ground and lets the
tiller rest on its drag bar.
3. As you’ll be propping up the
rear of the tiller next, first place a
support under the engine to prevent
the tiller from tilting too far. Now
slide three pieces of 2"x4" lumber
underneath the drag bar- raising
the drag bar about 4-V2" above
ground. This elevation allows an
accurate “cold” gear oil reading
(“cold” means 2 hours has passed
since the tiller was used).
4. Wait two hours with tiller ele
vated (allow more time if tempera
ture is below 40^F).
5. Loosen and remove transmis
sion dipstick (Fig. 5-8). Wipe it
clean with a rag.
6. Hold dipstick so its markings
face rear of tiller. Lower it straight
down into the sump hole to touch
the driveshaft inside (Fig. 5-8).
Don’t force or try to thread it back
in...an incorrect reading will result.
7. Remove dipstick and check oil
level. It should be anywhere with
in the cross-hatched area or even
slightly above the “Max” marking.
If correct, replace dipstick and re
move the boards used as props.
8. If oil level was low, gear oil
must be added before using the
tiller. See “C. Adding or Chang
ing Gear Oil” next.
For Dipsticks With Hot/Cold Markings:
1. Follow Steps 1 and 2 given for
the other type of dipstick.
2, Put a 2"x4" board under the
drag bar- raising the tiller and drag
bar about 3-V2" above ground.
This elevation is for a “cold” read
ing which is preferable- 2 or more
hours since tiller was last used. (If
taking a “hot” reading- tiller was
operated for more than 30 minutes
within the past hour, do not use the
wood prop to elevate the tiller.).
Figure 5-7: Remove oil level check
plug. Gear oil should seep out if
the level is sufficient.
Figure 5-8: Remove dipstick with a
9/16" wrench to check gear oil level
in tine attachment transmission.
Markings on dipstick must face rear
of tiller when checking oii level.
47
4. Follow Steps 4, 5 and 6 given
for the other dipstick type.
5. Remove dipstick 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 above the “Hot” range.)

C. Adding or Changing Gear Oil
For partial 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
orGL-5. For full replacement,
use SAE 140 or SAE 85W-140
gear oil with an API rating of GL-4
only. (At the Factory, SAE 85W140 weight gear oil is used.)
IMPORTANT - Do not use auto
matic transmission fluid or en
gine oil. They are too light in
weight and will result in trans
mission 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.
Gear oil is available at well-
stocked service stations, power
equipment centers, or farm/heavy
equipment outlets. (It may also be
ordered from Troy-Bilt.)
Capacities: Power unit transmis
sion holds approximately 60 ozs.;
Tine Attachment transmission
holds approximately 72-V2ozs.
To Add Gear Oil to the
Power Unit Transmission:
1. Follow steps 1 and 2 of “To
Check the Power Unit Oil Level:”
on the previous page.
2. Using a 3/4" wrench (or
socket), remove the bolt securing
the handlebar base to the top of the
transmission (prop the handlebars
first to prevent them from falling).
Then, unplug the Forward
Interlock wire harness receptacle at
the bottom of the handlebars. Set
the handlebar base and bolt aside
on a clean surface. The bolt hole
in the top of the transmission is the
gear oil fill hole. See Figure 5-9.
3. Slowly pour gear oil through a
clean funnel into the transmission.
Stop when gear oil begins to flow
from the oil level check hole on the
Figure 5-9: Gear oil fill hole (A) and gear oil drain location (B).
left side of the transmission
(Figure 5-7).
4. Reinstall the oil level check
plug. Tighten it securely.
5. Reinstall the handlebars using
the mounting bolt previously re
moved. Align the handlebars so
they point straight backwards, not
at an angle. Then tighten the
mounting bolt securely.
6. Reconnect the Forward
Interlock wire harness to the recep
tacle. Be certain it’s secure.
7. Test operation of the Forward
Interlock Safety System — refer
to Section 4 for procedure.
forward so any oil at the rear of the
transmission will drain out.
4. Clean the drain plug threads,
put non-hardening gasket sealant
on the threads, and reinstall plug.
5. Refill the transmission with the
correct amount of gear oil before
operating the tiller again. When
oil seeps from the oil level check
hole, the right amount of gear oil
has been added. Replace all plugs.
To Add Gear Oil to the Tine
Attachment Transmission:
1. Select the right depth regulator
lever setting:
a) If filling an empty transmission,
raise the Depth Regulator Lev
To Drain and Fill the Power Unit
Transmission:
1. Place a shallow pan under the
transmission gear oil drain plug
(refer to B, Figure 5-9).
2. Remove the oil level check plug
(see Figure 5-7) with a 3/8"
wrench. This vents the transmis
sion for faster oil draining.
3. Using the 3/8" wrench, remove
the drain plug (B, Figure 5-9).
The gear oil will drain quite slowly
since it is thick. After about two
quarts have drained, tilt the tiller
er so tines are on the ground.
b) If topping off the gear oil,
move Depth Regulator Lever
down to engage its top notch.
2. Remove dipstick from tine at
tachment (see Figure 5-8).
3. Slowly add gear oil in the dip
stick hole. Add 1/2-ounce at a
time to avoid overfilling. It takes
about I2-V2 ounces.
4. Take dipstick readings fre
quently. Stop when oil reaches
“Cold” range marking on dipstick.
Replace dipstick securely.

Page 49
To Drain and Fill the Tine
Attachment Transmission:
1. The tine attachment transmis
sion is not equipped with an oil
drain plug. To drain just a small
amount of gear oil, remove the dip
stick and tilt the attachment for
ward (first uncoupling it from the
Power Unit).
2. For complete drainage, remove
the left-side tine assembly (refer to
Bolo Tine Maintenance for instruc
tions), then remove just one of the
lower screws from the tiller hous
ing cover (Photo 5-10). To speed
drainage, remove the tine attach
ment dipstick to vent transmission.
3. Once all gear oil has drained,
reinstall the housing cover screw
securely (first coat its threads with
non-hardening gasket sealant).
4. Be certain to refill the transmis
sion with the correct amount of
gear oil before operating the tiller
again.
Note: If you find a plastic washer
on the cover screw you remove,
discard the washer. There is no
need to install a replacement
washer.

is installed), the belt tension will
probably need to be adjusted after
the first two (2) hours of operation.
Thereafter, check belt tension
every ten (10) operating hours.
WARNING
To help avoid personal injury,
stop the engine, wait for all
moving parts to come to a
complete stop, remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the spark
plug, and let the engine and
muffler cool before inspect
ing, adjusting or replacing
the drive belt.
On a new tiller (or if a new belt
While checking belt tension,
also inspect the belt for cuts,
cracks, deterioration, etc. Don’t
continue using a belt that isn’t in
good shape. You’re sacrificing
tiller performance by doing so.
Tips on keeping the drive belt in
top condition include:
• Always put the Wheels/Tines/
PTO Drive Lever in NEUTRAL
when the tiller is not in use.
• Keep tension adjusted correctly.
• Don’t “speed shift” when mov
ing the Wheels/Tines/PTO Drive
Lever between FORWARD and
REVERSE.
How to Measure Belt Tension:
1. Before taking a measurement,
be sure the linkages and pivot
points on the Wheels/Tines/PTO
Drive Lever are clean and lubri-
cated. If there is any binding, you
won’t get true measurements.
Also, you’ll need the belt adjust
ment tool you received with your
new tiller (see Photo 5-11).
2. Move the Wheels/Tines/PTO
Drive Lever fully down to the
EORWARD position. The clutch
roller at the bottom of the lever
should be positioned underneath
the belt adjustment block (Photo
5-12). Don’t let the clutch roller
move during the next few steps. If
it moves, you’ll get a false belt ten
sion reading.
Maintaining the right tension is
important to good tiller perfor
mance and long belt life. If too
loose, the belt will slip on the pul
leys, and be unable to deliver full
power to the wheels and tines. A
loose belt will also wear prema
turely.
Photo 5-11: Use this belt adjust
ment tool to measure and adjust
drive belt tension.
49
Photo 5-12: Shift into FORWARD
and measure distance between
roller and upright bracket using the
belt adjustment tool.
Page 50
3. The belt tension is correct if the
front of the clutch roller is l/4"-to5/16" away from the face of the
upright bracket that holds the ad
justment block in place (Photo
5-12). To measure this distance:
a) Without moving the clutch
roller, try inserting the 1/4"thick, slotted end of the belt ad
justment tool in between the
roller and the upright bracket.
(The flat edge of the tool must
be facing the roller.) Refer to
Photo 5-13.
b) If only the slotted portion of the
tool will fit, the belt tension is
correct as is.
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.
4. If the belt tension is correct,
move the Wheel s/Tines/PTO Drive
Lever back to NEUTRAL.
How to Adjust Belt Tension:
1. You adjust the drive belt tension
by loosening the bolt securing the
belt adjustment block, then moving
the block up or down. Moving it
down will tighten the belt; moving
it up loosens the belt. (Hint: the
distance the block moves approxi
mately equals the distance the
roller moves.) In most cases, the
clutch roller will not have been
very far out of position, so the ad
justment block will only need to be
moved slightly (up or down).
2. Move the Wheels/Tines/PTO
Drive Lever to NEUTRAL posi
tion. 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.
3. Insert the belt adjustment tool
through the hole in the side of the
adjustment block, spacing the ends
of the tool equally on both sides
(see Photo 5-14). Rotate the tool
so the slotted end faces down.
4. Place the Wheels/Tines/PTO
Drive Lever in EORWARD posi
tion. The arms of the clutch con
trol yoke will be resting on the belt
adjustment tool and the clutch
roller should be engaged slightly
beneath the adjustment block (see
Photo 5-15).

and bracket, with the flat side of the
slotted end facing the rolier.
5. Use one hand to hold the drive
lever in FORWARD while using a
9/16" wrench to loosen (don’t re
move) the bolt at the back of the
belt adjustment block (Photo 5-16).
The adjustment block should be
free to move either up or down.
6. Push the drive lever down if the
belt needs tightening. Or pull the
lever up if the belt needs to be
loosened. Hold the drive lever in
place and tighten the bolt in the ad
justment block firmly.
7. Let go of the drive lever and re
move the belt adjustment tool from
the hole in the adjustment block.

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

To help avoid personal injury,
stop the engine, remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the spark
plug, and let the engine and
muffler cool before removing
or replacing the drive belt.
To Remove the Belt:
1. Move Wheel s/Tines/PTO Drive
Lever to NEUTRAL position.
2. While kneeling on the right side
of the tiller, create slack in the belt
by reaching over to the left side of
the pulleys and pushing in on the
center of the belt with your finger.
3. Use your right hand to move the
belt down and away from the lower
pulley, in the direction of the en
gine (Photo 5-17).
4. As shown in Photo 5-18, push
the belt upward to create slack in
the belt.
5. Lift the top half of the belt up
and over the upper pulley and the
rubber reverse disc, moving it in
front of the reverse disc (refer to
Photo 5-19).
6. Push the Wheel s/Tines/PTO
Drive Lever down into the FOR
WARD position. This increases
the distance between the upper and
lower pulleys. Next, lift and pull
the entire belt out between the pul
leys (Photo 5-20).
3. Push belt forward then down
until it is looped over the lower
pulley (refer to Photo 5-18). Do
not yet seat it in either of the lower
pulley’s grooves. {Hint: a blunt
object, like a ruler, can help you
push the belt downward if needed.)
4. Move the top half of the belt up
and over the rubber reverse disc,
but do not seat it in either of the
grooves in the top pulley.
5. Place the Wheels/Tines/PTO
Drive Lever in NEUTRAL.
6. Move the top half of the belt
into the HIGH Range groove
(groove closest to the engine) on

These instructions explain how
But first, here’s how the reverse
mission pulley causes the transmis
sion drive shaft to be powered in a
counterclockwise direction (as
viewed from the operator’s posi
tion behind handlebars). The drive
shaft then turns the wheels and tine
shafts in a reverse direction.
A. Reverse Disc Inspection
The reverse disc is made of steel
with a special, long-lasting rubber
Photo 5-22: Measure the edge of
the reverse disc for wear.
compound bonded to the disc rim.
Since this is a wearing part, it
should be inspected after every 30
operating hours.
1. Measure the width of the out
side edge of the disc as shown in
Photo 5-22. Replace the disc be
fore the rubber edge wears to a
thickness of 1/8" or less. Failure to
do so could cause the steel under
neath the rubber to damage the
transmission pulley.
2. Look for big cracks or missing
chunks of robber from the disc. If
so damaged, the disc should be re
placed immediately.
IMPORTANT - Extend the life
of the reverse disc by always
pausing in NEUTRAL before
shifting between FORWARD
and REVERSE. Also - the re
verse disc is not suited for con
tinuous or sustained reverse op
eration. Use reverse sparingly.
B. Replacing the Reverse Disc
Follow these steps to replace the
reverse disc. (If your tiller has a
Bumper Attachment mounted, it
must be removed first.)
To Remove the Reverse Disc:
1. Move Wheels/Tines/PTO Drive
Lever in NEUTRAL position.
2. Wedge a 5/16"-thick board be
tween the top of the engine pulley
(avoid contacting the reverse disc)
and the cast iron housing next to it.
This “freezes” the pulley.
3. Use a 9/16" wrench to loosen
the mounting bolt shown in Figure
5-23. Remember to freeze the pul
ley with the wood wedge while
loosening the bolt. If necessary,
separate 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 re
move it. Bring the bolt and lockwasher along with the disc.
To Install a New Reverse Disc:
Just reverse steps l-through-3
described previously. Tighten the
mounting bolt securely, and check
for correct operation — see next
page for checking instructions.

C. Checking and Adjusting the
Reverse Drive System
WARNING
To help avoid personal injury,
stop the engine, remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the plug,
and let the engine and muf
fler cool down before inspect
ing or adjusting the reverse
drive parts.
When the Wheels/Tines/PTO
Drive Lever is moved up into RE
VERSE, the engine and engine
mount move down to press on the
reverse adjustment bolt (see Photo
5-24). This action compresses the
reverse spring and plunger assem
bly, requiring you to hold the lever
up in REVERSE. When you re
lease the lever, the spring automat
ically pushes the lever back into
NEUTRAL position.
number of reverse drive operating
problems, as explained next.
Check Action of Reverse Disc:
1. Verify that the linkages for the
Wheels/Tines/PTO Drive Lever are
lubricated with oil and the engine
mount bars and the belt adjustment
block are lubricated with grease.
(See “Tiller Lubrication” in this
section.)
2. Place the Wheels/Tines/PTO
Drive Lever in NEUTRAL.
Briefly pull out the engine recoil
start rope while watching the re
verse disc. The disc should turn,
but the lower pulley should not
(refer to Photo 5-25). If the re
verse disc turns the lower pulley, or
if it is located closer than 3/16" to
the pulley, the reverse adjustment
bolt should be adjusted upward
(see instructions that follow).
Moving the adjustment bolt up
ward will also solve the problem of
a tiller that goes into REVERSE on
its own.
3. Use your left hand to hold the
Wheels/Tines/PTO Drive Lever up
in REVERSE, while briefly
pulling out the engine start rope.
The reverse disc should turn the
lower pulley (see Photo 5-26). If
not, or it requires a lot of pressure
to hold the lever up in REVERSE,
then the 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 re
quire exceptional effort to hold it
up in the reverse position.
4. Shift the Wheels/Tines/PTO
Drive Lever to REVERSE and then
let it go. The lever should return to
NEUTRAL. If not, the reverse ad
justment bolt will have to be ad
justed upward.
Photo 5-24: Spring and plunger as
sembly.
The spring and plunger assem
bly is designed to prevent the re
verse 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 reverse ad
justment bolt (Photo 5-24). The
reverse adjustment bolt can be ad
justed up or down to correct a

Adjusting Reverse Drive:
1. Place Wheels/Tines/PTO Drive
Lever in FORWARD position.
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 (Photo 5-27).
While holding the bolt steady,
loosen the jam nut (counterclock
wise) until it touches the bolt head.
Photo 5-27: Hold bolt steady while
loosening or tightening jam nut.
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. Place a 7/8" wrench on the head
of the reverse adjustment bolt and
a 9/16" wrench on the jam nut
below it (see Photo 5-28). Hold
Photo 5-28: Loosen jam nut before
turning reverse adjustment boit.
the bolt steady while loosening the
jam nut three or four turns.
5. Move the Wheels/Tines/PTO
Drive Lever to NEUTRAL. The
switch body on the bottom of the
engine mount tab (see Photo 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 re
verse adjustment bolt (turn it coun
terclockwise).
6. Check that the reverse disc is at
least 3/16" away from the trans
mission drive pulley. Then hold
the reverse adjustment bolt steady
with one wrench while tightening
the jam nut with a second wrench
(see Photo 5-28).
7. Place a chalk or pencil mark on
the top edge of the plunger retain
ing bolt. Now, while watching the
mark, loosen the bolt 3/4-tum (see
Photo 5-29). Do not exceed a 3/4
turn (this would disengage the bolt
from the locking groove in the side
of the plunger).
8. Hold the plunger retaining bolt
steady with a wrench while tight
ening the jam nut against the side
of the plunger housing (Photo 5-27).
9. Check the action of the reverse
disc as explained previously.

BOLD TINE MAINTENANCE
^ WARNING
To help avoid personal injury,
stop the engine, wait for all
moving parts to come to a
complete stop, remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the spark
plug, and let the engine and
muffler cool before inspect
ing, removing or replacing
the fines or tine holders.
A. Checking Tines for Wear
Inspect the tines for wear or
damage after every 30 operating
hours. The rate of wear depends
upon hours of use and soil condi
tions. With use, the tines get
shorter, narrower and more pointed
(see Photo 5-30). If badly worn,
they lose the ability to till deeply.
Also, worn tines leave an 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".
Tines can be replaced individually
or as a complete set. See replace
ment instructions that follow.

from cuts or scrapes.
1. Move the Wheels/Tines/PTO
Drive Lever to NEUTRAL, the
Wheel Speed Lever to either FAST
or SLOW position, and the Tines/
PTO Clutch Lever to ENGAGE.
2. Gently tilt the tiller forward
until the engine rests on the ground.
3. Raise the hood flap at the back
of the tiller and tie it up with string.
4. Before removing a tine, note in
which direction the bent tip points.
The new tine must be installed in
the same direction.
5. Use two 9/16" wrenches to re
move the two bolts and nuts secur
ing the tine to the tine holder plate
(see Photo 5-32). Use penetrating
oil on the hardware if it is rusted or
hard to remove.
6. Mount the new tine exactly the
way the old tine was positioned.
(The sharp edge of the tine, which

enters the soil first, must face for
ward when above the tine shaft.)
Replace the bolts and nuts and
tighten them securely.
C. Removing and Replacing
the Tine Holders
£k
WARNING
The tines or tine hood edges
may be sharp. Wear thick
gloves to protect your hands.
The 16 Bolo Tines are mounted
eight per side on left-side and
right-side tine holders - on either
Style A or Style B holders (refer to
Figures 5-33A and 5-33B to see
which style tine holder you have).
Style “A” tine holders are secured
to the tine shaft with two bolts and
two nuts. Style “B” tine holders
are secured with a single end bolt
to the left and right sides of the
tine shaft. Here’s how to replace
the tines and holders as assemblies.
Removal Steps:
1. Follow steps l-through-3 in
“Single Tine Replacement” above.
2. Identify the tine holders as
Style A or Style B, then as left-side
and right-side holders - they must
be replaced on the same side from
which they were removed. Use a
piece of chalk or a grease pencil to
mark them “L” and “R.”
3. With Style A holders, remove
the two bolts and nuts securing
each holder (Fig. 5-33A). With
Style B holders, remove the single
bolt (along with the washers) from
the very end of the tine shaft (Fig.
5-33B).
4. Use a soft mallet to
drive the holder off the
tine shaft. (Use a heavy
Style A Tine Holder
hammer and block of
wood to drive off a
“frozen” tine holder.)
5. When the holder is
off, clean all dirt and de
bris from the shaft and
the holder. Apply fresh
grease to the tine shaft.
Replacement Steps:
1. Replace the holder so
the sharp tine edges face
forward (toward front of
tiller). Tap tine holder
back on the tine shaft.
2. Grease the threads on
the mounting bolt(s).
Install and tighten the
bolt(s) securely.

lated on the tine shaft or inside the
tine holders. Please follow 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 (see previous
page). After cleaning away any
debris and removing old grease
from the tine shaft, apply fresh
grease to the tine shaft.
Check tire air pressure every 30
operating hours. The recom
mended pressure for tilling is 10to-20 psi (pounds per square inch).
Both tires should be inflated
equally. (Unequal pressure can
cause the tiller to pull to one side.)
A
Removing the Wheels
WARNING
To help avoid personal injury,
stop the engine, wait for all
moving parts to come to a
complete stop, remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the spark
plug, and let the engine and
muffler cool before removing
or replacing the wheels.
Each wheel is secured by a roll
(spirol) pin that passes through the
wheel hub and the wheel shaft.
Drive the roll pin out to remove a
wheel.
1. Prop the transmission up with a
sturdy block to raise the wheel you
want to remove off the ground.
2. Move the Wheel Speed Lever to
either SLOW or FAST position to
prevent the wheels from turning.
3. Use a 5/16" drift pin (or a blunt
point 16-penny nail) to drive the
roll pin free.
A WARNING
Wear safety goggles when
driving the roll pin into or
from the wheel hub to protect
your eyes from the possibility
of flying metal particles.
ENGINE OIL MAINTENANCE
Change engine oil after first five
(5) hours of new operation. There
after, change the oil every ten (10)
operating hours. This may be more
often than your engine manufac
turer literature recommends, how
ever your tiller may be operating in
dirty or very dusty conditions.
Follow the engine manufac
turer’s literature for specific oil
changing procedures, quantity of
oil, and particular grade and vis
cosity of oil to use in your engine.
Locations to check the oil level and
to drain the oil are shown at right.
Note that there are two oil fill
plugs (one on each side) on the
Briggs & Stratton engines.
Figure 5-35: Oil fill plug on 7HP
Briggs & Stratton engine.
The engine is equipped with a
dual element air cleaner that filters
the air twice before it enters the
carburetor to mix with the fuel.
It is critical that the filters be
kept clean and properly installed at
all times. See the location of the
air cleaner assembly on your en
gine by referring to Figure 5-39 or
Figure 5-40.
Refer to the engine manufac
turer’s literature supplied with your
tiller for complete air cleaner ser
vice and maintenance information.
Figure 5-39: Air cieaner on the 7HP
Briggs & Stratton engine.
Figure 5-40: Air cleaner on the 8HP
and 10HP Briggs & Stratton engines.
THROTTLE CABLE
MAINTENANCE
WARNING
To help avoid personal injury,
stop the engine, wait for all
moving parts to come to a
complete stop,remove the
electric start key, disconnect
the spark plug wire and move
the wire away from the spark
plug, and let the engine and
muffler cool before adjusting
the throttle cable.
SPARK PLUG
MAINTENANCE
The spark plug (see Figure 5-
41) must be in good condition for
proper engine operation. Remove
and inspect the plug every 50 oper
ating hours or annually, whichever
occurs first.
The throttle lever settings are
factory-adjusted, so unnecessary
adjustments should not be made.
However, if the engine does not
start or stop, or respond immedi
ately to various throttle lever set
tings, then adjustments may be
necessary. Please refer to the en
gine manufacturer literature sup
plied with your tiller for specific
adjustment instructions.
Of course, you may contact
your nearest authorized engine ser
vice dealer for throttle cable ad
justments by a qualified service
representative.
IGNITION SYSTEM
MAINTENANCE
Your engine is equipped with
electronic ignition. It does not
have a 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.
The correct electrode gap for the
Briggs & Stratton engine is .030".
Check the gap with a feeler gauge.
Do not use a spark plug if the
porcelain is cracked, the electrodes
are pitted or burned, or if other vis
ible damage is present. Note: Do
not wire brush or sandblast the
spark plug to clean it - loose parti
cles can enter the engine, causing
damage!
Figure 5-41: Sparkplug (with boot
on) is on the top of the engine
(8HP/10HP engine shown).
To replace the 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
DANGER
POISON-CAUSES SEVERE BURNS
• Electrolyte is a sulfuric acid
solution.
• Avoid contact with skin,
eyes and clothing.
• To prevent accidents, wear
protective clothing, rubber
gloves, and shield eyes with
safety goggles.
• Neutralize acid spills with
baking soda and water solu
tion. Neutralize empty con
tainer with baking soda and
rinse with water.
ANTIDOTE: External- Flush
with water. Eyes- Flush with
water for 15 minutes and get
prompt medical attention.
ANTIDOTE: Internal- Drink
large quantities of water or
milk. Follow with milk of
magnesia, beaten eggs or
vegetable oil. Call physician
immediately.
KEEP OUT OF REACH OF CHILDREN
DANGER — BATTERIES
PRODUCE EXPLOSIVE GASES
• Keep sparks, flame,
cigarettes away at all times.
• Only charge or use the bat
tery in a well-ventilated area.
• Make sure venting path (vent
tube) of battery is always open.
DANGER
Never touch the positive (+)
battery post and any other
surrounding metal with tools,
jewelry, or other metal ob
jects. Doing so can cause a
short circuit that could result
in electrical burns, an electri
cal shock, or explosion of
battery gas.
A. Battery Care in Service
1. Every month or every ten (10)
operating hours, whichever comes
first, check the level of electrolyte
solution in the battery cells:
a) If the battery case has UPPER
and LOWER level lines on it, the
solution should be maintained at
the UPPER level line.
b) If the battery does not have level
lines on the case, maintain the
solution level at the lowest part
of the filler well within each cell.
Only use distilled or demineral
ized water to refill each battery
cell. After filling, replace the bat
tery caps securely, then wash off
any spilled solution with a baking
soda and water mixture. Next, run
the engine outdoors for about 20
minutes (at 3/4 throttle) to help
recharge and recirculate the elec
trolyte solution. For safety, do not
leave the tiller unattended while
the engine is running.
2. Keep the battery clean. If ter
minals are corroded, remove bat
tery and clean terminals with a
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 the terminals with petroleum
jelly or silicone grease to prevent
further corrosion.
3. Periodically check entire elec
trical system for loose connections
or loose hardware.
4. Check hardware securing the
battery holddown clamp. It should
be secure, but not overly tight.
5. Check the vent tube. It must
not be crimped or bent.
WARNING
To help avoid personal injury,
be sure the battery vent tube
is not crimped or pinched
anywhere aiong its iength.
Improper venting could result
in an explosion of battery
gases.
B. 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.
DANGER
• While the battery is being
charged, do not leave it unat
tended. Charging time does
not have to be continuous.
• Carefully follow all charg
ing instructions and safety
rules provided by the manu
facturer of the charging
equipment.
• Never attempt to “jump
start” the battery with an au
tomobile battery or its charg
ing system. This could result
in serious personal injury or
property damage from causes
such as a battery explosion,
or acid or eiectrical burns.

1. Remove the battery from the
tiller (see “Battery Removal” in
structions on this page) and place
on a stable, level surface.
2. Clean the battery if needed. If
the battery is very cold, let it warm
up to between 60-to-80°F.
3. Remove filler caps. Keep them
off when filling and charging.
4. Carefully check the electrolyte
level. If low, add distilled or dem
ineralized water (do not add battery acid) to bring the solution
level in each cell up to the correct
height. Avoid overfilling.
5. Charge the battery (with caps
removed) until all cells are gassing
freely. (To check for gassing, wear
protective goggles and inspect each
cell with a flashlight for bubbling
of the electrolyte solution.) Use
one of the following methods to
charge the battery:
a) Recommended Method: charge
the battery at a rate of l-to-2
amperes until cells are gassing
freely. Do not exceed 24 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) Second Alternative Method:
charge the battery at a rate of 6to-12 amperes until cells gas
freely. Do not exceed 4 hours
charging time.
rect height. Then reconnect the
charger cables to the battery and
charge the battery for one more
hour.
7. Replace the filler caps and wash
off any spilled electrolyte with a
baking soda and water solution.
8. Store the battery in a cool, dry
location. Avoid freezing tempera
tures. Batteries lose voltage when
in storage, more so in hot weather
than in cold. Ideal storage temper
ature is 50°F.
C. Battery Removal
and Replacement
WARNING
To help avoid personal injury,
stop the engine, wait for all
moving parts to come to a
complete stop, remove the
electric start key, disconnect
the spark plug wire and move
wire away from spark plug,
and let the engine and muf
fler cool before removing or
replacing the battery.
1. Disconnect the negative (-)
cable from the grounding screw on
the right side of the battery bracket
(A, Photo 5-42) and bend the cable
away from all metal parts.
2. Disconnect the negative cable
from the negative (-) battery post
(B, Photo 5-42), and remove cable.
3. Disconnect positive (+) cable
from positive battery post (C,
Photo 5-42) and bend it safely
away from metal parts. Cover
cable terminal with rubber boot.
4. Remove the battery holddown
clamp and remove the battery.
5. Reverse the previous steps to
replace the battery. The battery
posts must face 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.
WARNING
Wtren removing the battery,
always disconnect the nega
tive (-) cable first followed by
the positive (■«•) cable. Re
verse this procedure when re
installing the battery.
CAUTION
Do not charge the battery at a
rate higher than 12 amperes.
A charge rate greater than
this generates excessive heat
and gassing, and will perma
nently damage the battery.

STORING YOUR TILLER
When your tiller won’t be used
during the off-season, prepare it for
storage with the following steps:
1. Clean the tiller and engine.
2. Do routine tiller lubrication and
check for loose hardware.
3. Protect the engine from deterio
ration 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 the internal cylinder
against rust by removing the spark
plug and pouring one ounce of
clean engine oil into the spark plug
hole. Then slowly pull out the re
coil start rope 2 or 3 times to dis
tribute the oil internally. Replace
the spark plug, but do not recon
nect the plug wire. Pull the rope
until resistance is felt — let rope
rewind. The valves are seated.
INSPECT FORWARD INTERLOCK WIRING SYSTEM
Every ten (10) operating hours,
check the Forward Interlock wiring
system for tight connections and to
see that the insulation on the wires
is unbroken (to prevent the system
from shorting out).
1. Check the insulated wire har
ness leading from the lower ends
of the handlebars over to the wire
harness connector on the top, right
side of the transmission cover. Be
sure the connector is securely
mated.
2. Check the insulated tubing
leading from the connector to the
cast iron motor mount/belt shroud.
6. Charge the battery (if your tiller
has the electric start option). Store
battery in a cool, dry location.
7. Move Wheels/Tines/PTO Drive
Lever to NEUTRAL position.
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.).
3. Check the 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.
TROUBLESHOOTING THE FORWARD INTERLOCK SAFETY SYSTEM
The wiring circuit for the For
ward Interlock Safety System 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 NEUTRAL or
REVERSE positions. The other
two switches are located inside the
handlebars, directly above the two
Forward Interlock Levers. The
switches are wired in series, so
when any are opened (by squeez
ing one of the Forward Interlock
Levers), 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 connec
tion is not mated by not letting the
engine run while the
Wheels/Tines/PTO Drive Lever is
in FORWARD.
Only a few things can go wrong
with this circuit:
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 may act
as an open switch and allow the
engine to run. Or it may act as a
ground and prevent the engine
from running.
Refer to the Troubleshooting
pages at the end of this Manual if
your Forward Interlock Safety
System is not operating correctly.

ATTACHMENTS AND ACCESSORIES FOR YOUR TILLER
Hiller-Furrower Attachment
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.
Row Marker Attachment
Do you like very straight, even,
neat rows in your garden? If so,
the Row Marker is a must attach
ment. Ftooks quickly to the
Hiller/Furrower attachment- elimi
nates 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.
Dozer/Snow Blade Attachment
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-lbs.; measures 15" x 32".
Tire Chains
Chains provide extra traction
when snowplowing, or under wet
or slick conditions.
Tow Hitch Attachment
Converts your tiller to a tractortype 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.
Wheel Weights
Help increase traction by
putting extra weight directly on the
wheels. They reduce bucking and
jumping when deep-tilling in
heavy soil. They’re shipped
empty- fdl them with material like
concrete, sand, gravel, etc. They
bolt directly to the tiller wheels.
Wrap-Around Bumper Guard
Order this Bumper Guard by it
self or receive it as one of the com
ponents if you order the combina
tion Dozer/ Snow Blade attach
ment. Protects the engine from
damage by wrapping around and
protecting many of the engine
components. 1" diameter, high-
strength steel tubing.
