AUTOMATIC
RECOVERY BEAM
MA-7162
A

The
Automatic Recovery
Beam
is
de-
signed
to
relieve
itself
by moving
directly
back
and
up when
the
bottom encounters an
obstruction
in the
ground.
The
bottom
then
re-enters
the
ground
at the
proper plowing
angle without a reduction
in
forward
speed.
A
vertical
relief
feature
is
incorporated
which
allows
the
share
point
to glide
up and
over
sloping obstructions.
The
ability
of
the
plow bottoms
to
main-
tain the
proper
plowing depth
is
dependent
upon
the suction
of
the
bottom.
In fields
where
penetration
is a
problem
the suction
of
the
bottom must
be increased by
replacing
worn
shares or by
using shares
with better
penetrating qualities such as
deep suck
or
upset shares. Under some
soil
conditions
it
is
advantageous
to
use
the adjustable pitch
feature on
the
plow bottom.

21 C).
The
reversible adjusting block
(See
lllust. 19)
is
assembled
at
the factory with the
thin side engaged.
For
areas
having
extreme
surface
rock,
reverse
the block so
the thick
side
is
engaged reducing
tripping load and
providing
maximum
protection for the plow.
NEVER OPERATE THE PLOW UNDER ANY
CON-
DITION WITH
THE
ADJUSTING
BLOCK REMOVED.
Note:
Use
caution
when
plowing
in
fields with
large
rocks which
protrude 6 inches
or
more above
the
surface.
A
A
Caution! Automatic Recovery
Beams
operate
very rapidly and
are potentially dangerous
to
be near
at all
times while plowing.
Caution!
The
spring tubes
arc
and whip
at
a
fast rate
forward,
making
it
dangerous
to
ride
anywhere
on the
plow
frame.
A
Caution! Should
dirt
or trash
cause
a unit to
"hang up", stay clear
of
the area
near
the
unit.
To
remove
the obstruction,
use
a
long
pole
or hook.
SPRING TRIP
BEAM
The
beam
trips
are
set at the factory
to
break
at
a
load of
3,
100 pounds. Slacking
off
the
lock nuts
"AB"
will
decrease
the trip-
ping load.
By
tightening the lock nuts two
revolutions the tripping action
is
increased
to
maximum.
See
lllust.
20.
Increasing the tripping load
will
reduce
the
frequency
of
tripping
in
hard ground,
alfalfa, etc.
,
but
will at the
same
time
in-
crease
the possibility
of
bottom damage.
An
extra spacer block
(part
number)
524 594 Rl)
may
be obtained from
your
International
Harvester Company
dealer
and assembled
in
place as
shown
in lllust.
20.
Use
this
extra spacer block
only
where
plowing
is
extremely hard and
difficult
and
excessive
tripping occurs.
To
obtain the
maximum
protection for the plow
frame
and
bottoms
in fields
where stumps
and
stones
are
found,
use
only
the
spacer
block pro-
vided with
the
beam
units.
Note:
Hard
surface shares are
not
recom-
mended
for
rocky
conditions.
