To
The
Owner
Your new
International
Harvester
plow
is
designed
to
meet
today's
exacting
operat-
ing
requirements.
The
ease
of
operation,
and
ability
to
adjust
to
field
conditions
lighten
your
work and
shorten
your
hours
on
the
job.
You
are
urged
to
consult
your
International
Harvester
dealer
concerning
unusual
conditions
or
special
applications.
Let the
experience of
your
dealer
and the
organization
associated
with
him serve
you.
Be
sure
to read
the
instructions
for
Ad-
justing
and
Operating
in this
manual.
Check
each
item
referred
to and
acquaint
yourself
with
the
adjustments
required
to
obtain effi-
cient
operation
and
maximum
trouble-free
service.
Remember,
a
plow
which
is
prop-
erly
lubricated
and
adjusted
saves
time,
labor,
and
fuel.
After
the
operating
season,
thoroughly
clean
your plow
and
inspect
it.
Preventive
maintenance
pays
dividends.
Your dealer
has
original-equipment
parts
which
assure
proper fit
and
best
performance. He
is able
to
recondition
your
equipment
to a
like new
condition.
Your
plow
will
be
used
intermittently
during the
year. Rust
and
corrosion
must be
prevented
the
year
around. A
small
amount
of
time
and
effort
spent
protecting
it from
destructive
moisture
will
repay
you many
times
in
long
years
of
service, easy
opera-
tion,
and
high resale
value.
Of equal
impor-
tance
at the end
of the
operating
period
are
the
care
of
unprotected
surfaces and
pro-
vision
for
suitable
waterproof
shelter.

depending
on
the capacity of

TRACTOR
WHEEL
WEIGHT
It
is
recommended
that
the tractor rear
wheels
carry
added
weight for
increased
traction.
Adding
weight saves
wear on
the
tires
and also
serves
to stabilize
the
trac-
tor for plowing
on
rough or
hillside
fields.
For this
purpose,
liquid
such as
calcium
chloride
solution can be
placed
in
the rear
tires,
or one
or two
weight
(available
from
your
International
Harvester
dealer) may
be
bolted on
each
rear wheel.
In
loose soil
it may be
necessary
to use
both
the liquid
and the
weights to
prevent
excessive

important
factor
in

place the outside
draft

lever in
the extreme
forward
position).
See

The location of
the inside lever in
the

2. Draft
Control
(Not
recommended
for
on
the land
operation)
Draft
control is
that function
of
the trac-
tor
hitch
which responds
to variations
in
draft and does it
quick
enough to maintain
a
nearly constant
load
on
the
tractor.
When
the load on
the hitch
increases, the
hitch
responds
by shallowing
the front
end of the
plow,
which transfers
increased
weight to
the
tractor,
thus increasing
traction. A
choice of
two methods of
employing
"Draft
Control"
is available
as follows.

is

be
placed
near the front
of
the

See

The
plowing depth
of the front

plow
is
then
established
by moving
the outside
draft
control
lever from
"LIGHT"
to
"HEAVY"
until
the
desired depth
is attained.
On-The-Land-Operation
Use
the
inside control
lever to
help level
the
plow while operating
in the field.
As a
starting point
run the
lower link hitch
pins
about
17"
above the
ground.
(Draft
control
is
not
recommended.
Place outside
lever
in
an
extreme
forward
position).
The adjusting
stop may
be
set to
help
locate the
lever setting. It can then also
be
by-passed when
needed (as for quick entry
into
the
ground).
A
Caution!
Move
the Draft Control
lever forward
as
far as
possible when
the plow is discon-
nected.
The
speed
of hitch response to
changing
draft
loads can be varied
by moving the
in-
side control lever
past
the
offset,
into the
portion
of
the quadrant marked "RUN".
When the
lever is in the
extreme forward
position
load
sensing
is slow. When
the
lever is
located
just beyond the
offset
in
the
quadrant,
load sensing is fast.
See
lllust. 8B.
Any
lever
setting between
the two
extremes
may
be used depending
on field
conditions.
When lowering the
plow to start
plowing,
the
inside lever
should
not
be moved directly
to
the extreme forward
position as this
will
cause
slow entry
of
the
front
of
the plow
and
also
cause
the
rear cylinder to lower the
rear
of
the
plow too
slow.
A
CAUTION! Move the outside draft
control
lever forward
as far as possible
when
the
plow is
disconnected.

When
transporting,
or in the field, slow
down
before
turning. Do not use individual
tractor
wheel braking to make short turns.
This plow
has limit stops which do
not per-
mit pivot
turns.
SCOURING
If the
plow
bottoms
do
not scour im-
mediately, it
is
because
the
soil is rather
sticky and
you will
have
to wait until the
bottoms
have
taken
a land
polish. This may
require
a few
rounds or,
in
very
sticky
soil,
a
few days. To obtain this land polish, it is
recommended
that you
run
the plow
rather
shallow
and fast. It
is
also advisable
to
set
the
colters far to
the
outside of
the
landside
and
not too
deep.
Sometimes it
is necessary
to
remove
the
colters entirely
so as
to
ob-
tain
the
maximum pressure on
the plow
bottom
which aids in
scouring.
REAR FURROW
WHEEL
The purpose of the rear furrow
wheel
is to take part of
the
thrust
of the
landside
against
the
furrow
wall and to carry the
rear end of the plow when transporting.
The
adjustments
provided are especially
important when plowing hard
or
difficult
soils. Make certain
the tire is inflated to
the
recommended 40
pounds of air pres-
sure before
making adjustments.
The
bolt
"K"
in
II
lust.
10 serves
to
locate
the
axle
in one of five
possible positions
in the axle sleeve. Use the center position
for
average
conditions.
Note:
With
the use
of larger tires this adjustment is limited
by
tire
clearance
and
care should be taken
not to allow the
tire
to rub on the linkage.
Adjusting
the wheel
closer
to the
furrow
wall
can aid
in taking
side
thrust and
help
reduce
landside
wear.
Be sure
to completely collapse the
h/draulic
cylinder each
time the plow is lowered to operate.
