Inside Control Lever
(Position Control)
This lever
is
used
to
raise and lower
the
hitch
and
to
level the plow.
(When
beginning
to
operate
in
the
field,
place
the
outside
draft control lever
in the
extreme forward
position).
See
lllust. 7.
In-The-Furrow Operation
The
location of the inside lever
in the
quadrant
indicates the relative plowing
depth obtained.
When
the lever
is
placed
just
before
the offset
near
the front
end
of
the
quadrant,
maximum
depth
is
obtained.
As
the
lever
is
moved
toward
the
"RAISE"
position,
shallower depths
will
be
obtained.
Use
this
lever
to
establish the desired
work-
ing depth in the
field. See
lllust. 7.
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).

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.
