TYPES
OF PLOUGHING
Ploughing
is still the prime job in cultivating the earth and, despite this high
technological and computerised age, the basic design of the plough remains
largely unchanged since medieval times. There are several types of plough but
all are based on the same principle, with share, coulter and mouldboard. The
`Digger' plough has a short mouldboard and an acute curve causing the furrow
slice to rise steeply and accelerate thereby shattering the soil. This is known
as `broken furrow' work.
The
more common type of plough is the `general purpose' with a longer and shallower
and more gently curved mouldboard. This will lay up furrows in the `Whole
Furrow' fashion.
By
far the most intricate style of ploughing is the `High Cut' or `Oat Seed
Furrow'. The plough has a very long convex mouldboard with a gentle twist and
uses special shares to set up narrow, high crested furrow slices. In competition
this plough is set within tolerances of a quarter of an inch.
Ploughing
Matches have been part of the rural scene since time immemorial and in the early
days a champion ploughman could expect a better wage than his fellows.
Competition was keen and made for accurate plough setting. Plough manufacturers
saw the advantages of scientific design that would decrease the physical effort.
Today we see a continuance of this search for perfection and Plough Match judges
look critically for furrows that are perfectly straight, evenly matched, and
completely level. The judges will mark each plot up to a possible 200 points,
divided into five sections of a maximum of 40 points each.
The START of CROWN should be straight and level with no gap between the first two opposing furrows. FIRMNESS is very important; the work should not be hollow or puffy and there should be no `holes' between the furrow slices. The SEEDBED is judged by the quantity of soil presented by the plough on each furrow slice. The work should not be flat, neither should any stubble or trash be visible between the furrows. GENERAL APPEARANCE of the ploughed plot should be straight, uniform and perfectly matched furrows of equal width and even depth. The FINISH should be straight, narrow and shallow. This is probably the most difficult part to perform since the work must be brought to a conclusion perfectly parallel.
HIGH
CUT PLOUGHING
To
enable the spectators at today's Match to better understand what is going on, a
little detail of the `High Cut' Class may be helpful.
Competitors,
some of whom have travelled 100 miles or so, will arrive early at the site to
give sufficient time to off load their tackle, collect their plot numbers from
the Secretary and make their way to the starting pegs. There they will
painstakingly set up their three sighting poles and await briefing by the Class
Steward. He will remind them of the rules and in particular the depth of
ploughing.
On
the signal to start, the ploughs will be put into the ground for the first time
today, since no practicing on the site is allowed. The Ploughmen will
concentrate on drawing the straightest possible `scratch furrows'; these will be
used as a base for the crown. These first shallow furrows will give some
indication of the nature of the land and will suggest the type of share that
should be used. The style of work is greatly influenced by the lift on the wing
of the share.
One
of the most difficult parts of the match is to get the first four furrows of the
Crown level and matching. You will see the Competitors constantly making
adjustments to the width and depth of their ploughing and at this stage they
will be using one furrow only, the front body running idle so as to mould the
previous furrow slice if necessary.
Having
completed the Crown of six furrows each side, the ploughman will measure the
width of the land between his own work and that of his neighbor. He will want
this parallel since this is the area he will plough to complete his plot.
You
will notice how slowly the work proceeds. The reason for this is to keep the
furrows as unbroken and intact as possible. The object of `High Cut' ploughing
as devised very many years ago, was to enable grain to be broadcast by hand on
tightly packed and high crested ploughing, so that with a single stroke of horse
harrows across the furrows, the seed was buried at a uniform depth. It would
then grow through in drills 7 or 8 inches apart. This style of ploughing is so
precise that under ideal conditions, and remembering that the corn was
broadcast, the emerging crop could be hoed.
As the Ploughman nears the finish, he will shallow up an inch or so from the previous 6 inch depth. He will also make frequent measurements of the remaining land so as to keep the work parallel, otherwise he may leave an ugly short furrow and find it difficult to finish straight.
GLOSSARY
OF PLOUGHING DEFINITIONS
Semi-digger
Ploughing:
Semi-digger ploughing is a broken, rounded furrow, which can be easily worked down into a tilth. The semi-digger plough has a slightly concaved mouldboard.
Whole
Work:
Whole
work is an unbroken furrow not turned over as much as a semi digger furrow. The
whole furrow plough has a slightly convex mould-board.
Oat
Seed Furrow (otherwise known as high cut):
A
type of ploughing upon which seed could be sown by hand. The oat seed furrows
are narrow and tightly packed together in the shape of equilateral triangles.
The plough has a long mould-board with a gentle turn.
General
Purpose Ploughing:
A
type of ploughing which is adaptable to lea, stubble or root crops.
Crown
(otherwise known as ridge middle, crop or centre):
This
is where the ploughing is started with the furrows facing each other done in
different directions.
Finish
(otherwise known as furrow or rein):
Constitutes
the last three rounds in the centre of the ploughing where the ploughman
finishes his plot.
Furrow:
The
space left when the mould-board has turned the soil over.
Headland:
The land upon which the ploughman turns round in order to plough in the opposite direction.
PARTS
OF THE PLOUGH
Mould-board
(otherwise known as the breast):
The
mould-board is the part of the plough which turns over the soil.
Share:
The
principle cutting part of the plough, fitted to the front of the mouldboard,
making the horizontal cut of the furrow. The type of share varies with different
types of ploughing.
Tailpiece:
A
flat piece of metal extending beyond the end of the mould-board to ensure the
soil is well turned.
Coulter:
A
knife or cutter attached to the frame of plough ahead of the mould-board, which
makes the vertical cut in the furrow.
Disc:
A
thin flat revolving disc used instead of a coulter.
Skimmer:
A
miniature plough fixed to the side of the disc, set to skim a shallow furrow in
line with the disc, so that when the furrow is turned all the grass or stubble
is covered.
Boats
or Press Wheels:
These
are not part of the plough but are subsidiary pieces of equipment used on the
upturned furrow as an aid to improving its appearance and perfecting its shape
(used in oat seed furrow).
