Its
9.00 in the morning.
The sun is up and it looks like its going to be a really hot day.
Fiona takes to the field with the turbo-mower - time to make some
haylage!
The
turbo-mower is a power-driven machine that consists of rotating
drums that are fitted with cutting blades at their base. As they
spin round at speed, they mow the crop and shed the cut material
into neat rows behind.
Turbo
mowers can be set to cut extremely close to the ground, thus maximising
the quantity of cut material.

Silage is a grass crop that is cut when it is very green. The
cut material is collected and stored in a large pit back at the
farm. The pit is covered with a polythene sheet to minimise exposure
to the air. In this enclosed environment, the crop remains in
a preserved state. Once exposed to the air, it begins to deteriorate
at a normal rate.
Hay
on the other hand is cut at a later stage of growth, dried in
the field then baled up, ready for storage. Hay requires to be
dry when harvested, as it will spoil by mould and rot if stored
wet.
Haylage (the crop that is being harvested today) is really a combination
of the two forms since the
large bales of haylage will be enclosed in air-tight polythene
- achieving the same conditions found in a silage pit, yet offering
the flexibility of bale-sized amounts of feed.
|
|
Its
11.30 and the day is really warming up.
A gentle breeze is blowing from the west - this is good, the crop
needs to dry out a little before baleing.
Richard
is 'tedding' the hay. This involves passing the rows of cut grass
through a machine that lifts it off of the ground and throws it
into the air. This has the effect of 'fluffing up' the crop, simillar
to what you might do to a feather pillow.
This lets the air move through it more efficiently and allows
the crop to dry faster.
|

|
Seen
from a different angle, the tedding machine has rotating arms
that grab the hay at speed, ejecting it into the air behind the
machine.
There
are two basic settings on a tedder.
One setting throws the hay out the back of the machine, spreading
it into a thin uniform layer. This is useful for initial drying
of the crop.
The second setting gathers up any hay that passes in front of
the machine and ejects it into a high fluffed up row behind. This
setting is good for drying the crop by air and also creates neat
rows for the baleing machine.
|

6.00 in the
evening, and the crop is ready for baleing.
There are
many different machines on the market for processing hay into
bales. The bale sizes can range from small rectangular types to
large round bales.
We will be
using a round baler for the haylage. This is because we want a
decent sized bale for feeding our cattle herd. Once a bale is
opened, it begins to deteriorate in quality, so it is a good idea
to use the whole bale as soon as possible when feeding.
Small bales, although easy to move around by hand, would be numerous.
This adds to the time factor when wrapping (and the cost per bale
too). Small bale sizes are popular for feeding individual animals
such as horses and ponies because they also suffer from the same
problems of quality after they are opened.

As
the baler devours the hay, it feeds it into a chamber where a
series of rollers compresses and rotates the crop into a tight
bundle.
As
more and more hay is added to the chamber, it grows into a cylindrical
bale, rather like a giant swiss roll.
When
the bale is completed, the machine wraps a strong webbing around
it to ensure it will not unfurl.
Finally, the baler opens up and ejects the bale onto the field.
|
|
Its now getting
on for 9.00.
The light
is fading fast, but the baleing is finished and the crop is safe.
When the bales are eventually used to feed the cattle, the bale
can be unfurled easily, forming a long carpet of fodder.

Its
nearly 9.00 in the morning.
The weather looks like its going to change. Although the sun is
shining, the clouds are gathering and it feels like rain is a
possibility - time to get those bales in!
Fiona is out in the field loading bales onto the trailer.
The front loader on her tractor has a special spike attachment
that is used to lift the bales.
|
|
Its not looking
any better out to the west, maybe we will be lucky and miss the
rain.
The trailer is almost loaded. It can accommodate 10 bales with
ease - (5 bales to each side).
The trailer will be dropped at the farm for unloading. Another
empty trailer will be driven back to the field for loading.
If all goes well, an empty trailer should be waiting for uplift
each time a full one is delivered to the farm.

Richard
is unloading the trailer back at the farm.
He places each bale on a machine that quickly wraps a polythene
film around it.
Notice the special lifting attachment on the arm of the fork lift.
Essentially, this is two bars that cradle the bale on either side.
This lifter is used because the spike method would puncture the
wrapped bale.
When the wrapper has done its job, it tips the wrapped bale out,
ready to accept the next bale.
The previous bale is in the foreground, all wrapped up and waiting
to be stacked.
|
|
This is a
close-up picture of the wrapping machine.
The bale nests on two rollers, one on each side. The rollers are
part of a rotating platform.
The black polythene film is attached to the bale and the wrapping
process begins.
The bale is slowly rotated anti-clockwise between the two rollers
and the complete platform assembly also rotates anti-clockwise.
The effect of these rotations causes the film to wrap around the
bale over and over whilst under tension. This forms a poythene
cocoon around the bale and makes it completely air-tight.

Again,
using the special lifter, the wrapped bales are moved to their
final storage position. Any tears in the polythene are patched
with sticky tape (Duck Tape), as is the loose flap that was left
after wrapping.
They
will be left here to mature then used to feed cattle later in
the year.
By late afternoon, all the bales were wrapped and stored away.
Only one short shower of rain actually fell and the skies cleared
up afterwards.
