designed
for
seed
bed
preparation,
cultivating,
furrowing
and
mulching.
It
is
engineered
to
minimize
the
harcest
work
in
the
vegetable
or
flower
garden,
to
till
the
soil
for
planting
and
cultivating,
and
for
perform¬
ing
many
other
useful
labor
saving
tasks
in
the
garden.
With
the
proper
amount
of
care
and
maintenance,
this
machine
will
provide
the
owner
with
many
years
of
excellent
service.
WHEEL
POSITION
The
tiller
is
shipped
with
the
wheels
adjusted
such
that
the
unit
sits
level.
During
digging
as
the
tines
enfer
the
ground
and
the
front
of
the
tiller
lowers,
the
wheels
must
be
raised
to
level
the
unit.
This
is
essential
for
proper
engine
operation.
This
adjustment
is
made
by
removing
the
clevis
pin
and
hairpin
cotter
from
wheel
yoke,
raising
the
wheels
to
the
desired
height,
and
replacing
the
clevis
pin
and
hairpin
cotter.

Adjustment:
The

acts
as

which
the
machine
will

By
increasing
the
depth
of
the
depth
bar,
the
for¬
ward
speed
of
the
machine
is
reduced,
and
the
working
depth
is
increased.
When
the
depth
bar
is
raised,
the
working
depth
of
the
machine
is
re¬
duced
and
the
forward
speed
is
increased.
The
working
depth
of
the
machine
may
be
predeter¬
mined
by
setting
the
depth
bar
and
wheels
so
that
the
wheels
are
about
four
inches
from
the
ground
when
the
tines
and
depth
bar
are
resting
on
the
ground.
This
setting
will
permit
a
working
depth
of
about
four
inches.
When
presetting
the
working
depth,
the
handles
should
be
a
little
above
waist
height
because
the
complete
tiller
will
be
lower
when
the
tines
and
depth
bar
penetrate
the
ground.
The
best
method
will
be
determined
by
the
soil
condition.
In
some
soils,
the
desired
depth
is
obtained
the
first
time
over
the
garden.
In
other
soils,
the
desired
depth
is
obtained
by
going
over
the
garden
two
or
three
times.
In
the
latter
case,
the
depth
bar
should
be
lowered
before
each
succeeding
pass
over
the
garden,
and
passes
should
be
made
across
the
length
and
width
of
the
garden
alternately.
Rocks
which
are
turned
up
should
be
removed
from
the
garden
area.
3.
Handle
Pressure:
Further
control
of
tilling
depth
and
travel
speed
can
be
obtained
by
varia¬
tion
of
pressure
on
the
handles.
A
downward
pressure
on
the
handies
will
reduce
the
working
depth
and
increase
the
forward
speed.
An
upward
pressure
on
the
handles
will
increase
the
working
depth
and
reduce
the
forward
speed.
The
type
of
soil
and
working
conditions
wilt
determine
the
ac¬
tual
setting
of
the
depth
bar
and
the
handle
pressure
required.
4.
Throttle
Control:
The
throttle
control
lever
is
located
on
the
right
side
of
handle
panel.
Right
hand
side
is
determined
from
the
operator’s
position
standing
behind
the
tiller.
The
throttle
control
lever
adjusts
the
engine
speed.
It
also
gives
finger
tip
control
of
the
car¬
buretor
and
magneto
stop
switch.
With
the
throt¬
tle
control
knob
pushed
completely
forward,
the
carburetor
is
in
START
position.
Pulling
the
throt¬
tle
control
back
slightly
adjusts
the
engine
speed
to
FAST.
Pulling
the
throttle
back
further
reduces
the
engine
speed
to
SLOW.
When
the
throttle
is
pulled
completely
back,
the
magneto
stop
switch
grounds
out
the
spark
and
stops
the
engine.
Use
maximum
engine
speed
for
deep
tilling.
Move
the
throttle
control
to
siow
when
transport¬
ing
the
tiller.
When
the
tiller
is
being
moved
to
or
from
the
garden,
the
depth
bar
should
be
pivoted
forward
until
it
engages
the
depth
bar
spring
pin.
The
machine
may
be
moved
under
its
own
power,
without
damaging
grass
areas
as
long
as
it
is
allowed
to
move
freely.
If
the
operator
holds
back,
it
will
start
to
dig.
CULTIVATING
For
cultivating,
a
two
to
three
inch
depth
is
desirable.
Setting
the
wheels
and
depth
bar
so
that
the
wheels
are
about
two
inches
above
the
ground
while
the
tiller
is
resting
on
the
tines
and
depth
bar
will
allow
the
machine
to
work
at
cultivating
depth.
The
throttle
should
be
set
to
control
forward
movement
to
a
slow
walking
speed.
With
standard
tines,
the
maximum
working
width
of
the
tiller
is
26
inches.
This
width
may
be
reduced
to
24
inches
by
moving
the
clevis
pins
and
hairpin
cotters
to
the
inner
holes
on
the
tine
shaft.
For
cultivation,
remove
the
outer
tines
to
obtain
a
tilling
width
of
13
inches.
When
laying
out
plant
rows,
be
sure
to
allow
enough
width
to
permit
cultivation
between
the
rows.
In
growing
corn
or
similar
crops,
check-row
planting
will
permit
cross
cultivation
and
prac¬
tically
eliminate
hand
hoeing.
The
tiller
has
many
uses
other
than
tilling
and
cultivating
a
garden.
One
of
these
is
the
prepara¬
tion
of
lawn
area
for
seeding.
The
tiller
will
prepare
a
deep
seed
bed
which
will
be
free
of
hard
unfilled
spots,
allowing
a
better
stand
of
grass
to
grow.
The
tiller
is
very
useful
for
loosening
hard
soil
for
excavation
with
a
shovel.
No
tedious
hand
pickwork
will
be
necessary.
Your
tiller
may
be
used
for
mixing
compost
in
the
pile,
or
for
mixing
it
with
the
soil
in
your
garden.
This
should
be
done
after
the
soil
has
been
broken
to
the
full
working
depth.
The
compost
should
be
worked
in
to
a
depth
of
six
to
eight
inches.
This
may
be
done
by
working
the
length
of
the
garden,
and
then
by
mix¬
ing
separate
passes
across
its
width.
The
addition
of
decayed
organic
matter
will
substantially
in¬
crease
the
fertility
of
your
garden.
For
proper
decaying
action,
fertilizer
should
be
applied
and
worked
in
with
the
mulch
materials.
Breaking
up
leaves
and
straw
and
mixing
it
with
several
inches
of
soil
causes
the
soil
to
hold
moisture
longer
and
allows
proper
aeration
of
the
plant
root
system.
It
also
retards
the
growth
of
weeds.
The
U.S.
Department
of
Agriculture
and
various
state
and
local
agencies
offer
published
booklets
and
expert
advice
on
all
phases
of
gardening.
They
should
be
consulted
regarding
soil
informa¬
tion,
planting
dates,
and
the
most
satisfactory
varieties
of
crop
for
your
particular
area.

AIR
CLEANER
The
air
cleaner
prevents
damaging
dirt,
dust,
etc.,
from
entering
the
carburetor
and
being
forced
into
the
engine
and
is
important
to
engine
life
and
per¬
formance.
To
service
air
cleaner,
refer
to
the
engine
manual
packed
with
the
tiller.
Never
run
your
engine
without
air
cleaner
com¬
pletely
assembled.
CLEAN
ENGINE
Wipe
off
all
spilled
fuel
and
oil.
Keep
the
engine
clean
of
foreign
matter
and
be
sure
the
cooling
fins
on
the
cylinder
are
kept
clean
to
permit
proper
air
circulation.
This
is
an
air-cooled
engine
and
free
flow
of
air
is
essential
to
proper
engine
per¬
formance
and
life.
SPARK
PLUG
The
spark
plug
should
be
cleaned
and
the
gap
reset
at
least
once
a
season
or
when
oil
is
changed.
Spark
plug
replacement
is
recom¬
mended

OFF-SEASON
STORAGE
If
the
tiller
is
not
to
be
used
for
a
while,
the
follow¬
ing
procedure
should
be
followed.
The
tines,
depth
bar,
gear
case
and
wheels
should
be
cleaned
of
all
dirt.
It
is
very
important
that
the
unit
be
stored
in
a
level
position
to
prevent
engine
oil
from
draining
into
the
cylinder
head
cavity.
Engines
on
tillers
to
be
stored
between
seasons
should
be
completely
drained
of
fuel
to
prevent
gum
deposits
forming
on
essential
carburetor
parts
and
fuel
tank.
Refer
to
the
engine
manual
for
correct
engine
storage
instructions.
Just
as
your
automobile
needs
professional
mechanical
maintenance
from
time
to
time,
so
does
your
air-cooled
engine.
Cleaning
and
ad¬
justing
of
the
carburetor
and
periodic
replacement
of
the
spark
plug
and
ignition
points
is
made
necessary
by
NORMAL
use.
Professional
Air-Cooled
Engine
Service
is
as
close
as
your
telephone
book.
A
yearly
checkup
or
tune-up
by
an
authorized
engine
dealer
is
a
good
idea
to
avoid
breakdowns
or
delay..
.do
it
at
the
end
of
the
season,
then
you’re
ready
for
the
next.
NOTE
When
storing
any
type
of
power
equipment
in
an
unventilated
or
metal
storage
shed,
care
should
be
taken
to
rustproof
the
equipment.
Using
a
light

coat
the
equipment,
especially
any
