Most Tractor Plows Not Adjusted
Properly; Three Changes to Make
Nine out of ten tractor plows
are adjusted improperly. That's
what a survey made some time
ago in Ontario showed.
Basically, there are three ad-
justments which can be made to
a plow, states Don Clark, Depart-
ment of Engineering Science, On-
tario Agricultural College. These
are the heel clearance, the land -
side pressure, and the coulter.
Heel clearance is the measure-
ment between the bottom of the
landside and the bottom of the
furrow. If the landside does not
have a replaceable heel casting,
the clearance when measured on a
hard surface, should be one-quar-
ter of an inch for hard, dry soils,
and up to half an inch for soft,
moist soils. If the landside does
have a replaceable heel casting,
the casting should leave a slight
mark at the bottom of the furrow
when plowing.
The landside pressure adjust-
ment when adjusted properly on
three -wheeled plows reduced the
draft by causing some of the side
thrust of the plow to be carried
on the rear wheel instead of be-
ing carried on the landside of the
plow bottom. On two -wheeled
plows, as well as on mounted
plows, there is usually no special

adjustment for landside pressure;
the horizontal hitch of the plow
to the tractor or the design of the
bracket that attaches the rolling
landside to the plow beam usually
controls the landside pressure.
On three -wheeled plows the
landside pressure is checked by
laying a straight edge against
the point of the share and against
the rear wheel. Then the distance
from the rear of the landside to
the straight edge is measured. The
measurement should be between a
quarter and three-eighths of an
inch.
The coulter adjustment is im-
portant. The adjustment of any
rolling coulter is affected by the
condition of the soil to be plow-
ed and the sharpness of the coul-
ter itself. The coulter can be ad-
justed three ways: •
The first adjustment is the
depth of cut. The general ' setting
is one and a half to two inches
clearance between the point of
the share and the cutting edge
of the coulter blade. If the soil
is ver -y hard or the coulter dull,
it will be necessary to increase
this clearance so that the plow
will not "ride" on the coulter
and thus not allow the plow to
Of Many Topics,
Future in Farms
Do you ever worry about the
fact that your freedom as a citi-
zen seems to be slipping away
from you? Have you wondered
what will happen to farming when
the packing companies and feed
mills take over ? If they take ov-
er! Is a lack of credit to run your
farm stopping you from doing the
things that you'd like to do? Could
farmers borrow a leaf from the
book of labour unions and use
stronger organizations as a means
to more freedom?
These are just random questions
picked from the list which spark-
ed the 1958-59 National Farm For-
um topics. They represent ques-
tions asked of farm people, and
by farm people, over the years
And they hit on some of the most
crucial problems of farmers to-
day.
Take the subject "Vertical Inte-
gration," for instance. In the Unit-
ed States, where its growth has
been charted, whole counties and
even States, have gone into con-
tract production, while the little
farmer's living has dwindled. Men
who got into the integration early,
as far back as 1937, now control
millions of broilers, thousands of
hogs, and literally hundreds of
thousands of laying hens.
What does this mean for Cana-
dian agriculture? Well, during
January, every Monday evening, at
8:30, National Farm Forum will
try to find out.
Then, very shortly . . : on Nov-
vember 3, the subject will be
"Freedom." Can we have person-
al freedom today? Or should it be
replaced with a stronger, more
useful kind . . freedom through
an organization? That program is
also at 8:30 and it will feature
some thought-provoking panelists.
And on the 17th of November,
Farm Forum invades the show -
ring. What has it done for agri-
culture? What will performance
testing do to the show -rings? Is
show livestock out of date?

penetrate to the domed depth.
The second adjustment is the
position of the coulter on the
plow beam. The usual position is
to have the bearing of the coulter
directly above the point of the
share.
The third adjustment concerns
the clearance between the coul-
ter and the landside. The easi-
est way to set the coulter to the
land is to hold a board which is
three-eighths to three-quarters of
an inch thick, on edge against the
position of the coulter on the
landside and extending forward
beyond the point of the share.
Then the coulter shank should be
adjusted until the coulter is paral-
lel to the board.
These basic adjustments should
be made before the plow is taken
into the field. Then these adjust
ments can be modified in the
field to suit various soil conditions.
Hitch adjustments can easily be
made in the field.
The instruction book obtained
with the plow should be followed
closely.
