5. BALE WRAPPING
Bale Wrapping Principles
The advantages of round bale silage are many, and include fewer feed units, a exible harvesting system, large capacity and the possibility of selling feed units.
In principle, the same fermentation processes occur whether the fodder is placed in a silo or pressed into bales and packed in plastic, i.e. lactic acid fermentation in anaerobic conditions.
The oxygen in the bale must be exhausted before fermentation begins.
The grass should be dried to approximately 30-40% solid content. The solid content can be determined by twisting the grass by hand. If drops of liquid are forced out of the grass, the
solid content is less than 25%. Low solid content (wet grass) can lead to increased butyric acid fermentation if preservatives are not added to the grass. If the solid content is too high,
(over 50%), normal fermentation will not take place and there will be enough oxygen in the bale to produce mould fungus.
The Baler
It is vital that the baler produces compact, well-formed bales, as misshapen bales can be dicult to wrap. Wrapping will also often take longer, thereby increasing the amount of plastic
used.
Dicult Bales
When a misshapen bale is wrapped, it will have a tendency to move outwards or inwards on the roller. If the bale begins to move outwards, the machine must be lifted slightly at the rear
edge to get the bale to rest against the support roller on the main frame. It can therefore be useful to use a hydraulic top link to make this adjustment easier.
If the bale to be wrapped is conical you must ensure that the sharp end is pointed at the tractor. It will then be easier to get the bale to lie correctly during packing. It is easy for such a
bale to “turn” forward in the direction in which it is pointing, and therefore lie against the support rollers. If the bale is lying on a slope it must be picked up from the lower side. A hydrau-
lic top link will again be advantageous.
Types of Plastic
A good type of plastic with good adhesive properties, and which is recommended for bale wrapping, must be used. The thickness of the plastic foil should be at least 25 µ. (25/1,000 mm).
In order that the plastic tightens suciently around the bale, it is stretched before being wrapped, so it is somewhat thinner when it is put on the bale. With short-term storage (up to
eight weeks) it is recommended that bales have a minimum of four layers of plastic at the thinnest points, with at least 52-53% overlap.
For long-term storage, or when the grass is wet when it is wrapped, the bale should have 90-100 µ plastic (six layers) and the same amount of overlap. If thinner plastic is used, more lay-
ers should be applied. If it is very hot the plastic will be stretched further, and more layers should be applied. It is better to have slightly too much than too little plastic on the bale.
From experience, light colored plastic produces slightly lower temperatures within the bale, and tends to improve feed quality.
Storage Location
Care should be taken in nding a suitable location for the storage of bales. The storage location should preferably be prepared before the bales are laid out. An elevation close to well-
drained roads is recommended. If the wrapped bales are simply placed on stubble there is a danger of the plastic being pierced. A tarpaulin or a thin layer of sand should therefore be laid
where the bales are to be stored over the winter.

5. BALE WRAPPING
Bales should be stored in the shade as far as possible. This reduces the danger of air leakage in the bales. A bale which is stored in sunlight and which therefore undergoes greater swings
in temperature “pumps in” a great deal of air in comparison to a bale stored in the shade. According to “Teknik for Lantbruket” [Technology for Agriculture] in Sweden, a bale stored in the
shade has only 40% of the air leakage of a bale which is stored in sunlight.
Stacking / Protection
If bales are hard and well formed, they can be stacked vertically, but loose and misshapen bales with low solid content should not be stacked higher than one layer, as this could easily
cause deformity and the danger of runo will be increased.
Bales can also be stored on their sides. The layer of plastic is thicker here, providing greater protection against piercing.
Bales should be covered with a tarpaulin or a ne-mesh net to protect against birds and small rodents. If the plastic is pierced, it must be sealed with weatherproof, hard-wearing tape,
preferably under the outermost layer of plastic. Ensure that the hole is adequately sealed.
For Best Wrapping Results...
1. Harvest the grass early.
2. Ensure the grass is dried out to 30-40% solid content. If there is a danger of rain, bale and wrap the
grass anyway.
3. Take care not to mix any earth in with the grass.
4. Use a baler that produces even, rm bales. Bales 1.2mtrs in width and with a diameter of 1.2-1.5mtrs
are preferred sizes.
5. Wrap the bales as soon after baling as possible; never more than two hours afterwards.
6. Use a good plastic type, applying six layers of plastic. This removes the need to use preservatives.
7. Store bales in the shade to reduce the danger of air leakage.

6. MACHINE SETUP
Mounting of the Machine
Be careful! There is a danger of being crushed when working implements are tted and connected. Carry out the tting procedures slowly and carefully, and use separate and
approved lifting equipment to make the work easier. Note the section on safety precautions and pay attention to the various safety decals displayed on dierent parts of the bale
wrapper.
Three Point Linkage
TANCO AUTOWRAP A200 EH model is intended for rear mounting to the three point linkage, Category 2. When attached to three point linkage, make sure the machine is level across the
tractor. Tighten up and lock the lifting arms so there is no sideways movement.
Top Link
Adjust the top link of the tractor so that the machine is level with the ground. It is recommended to use a hydraulic top link, as this makes it easy to adjust the angle of the machine.
During the wrapping process it is recommended to tilt the machine towards the tractor, as this will prevent the bale from falling o the turntable.

A200 EH Control Box
A200EH Controller
The A200EH electronic controller activates the automatic functions of the machine and also enables the operator to manually operate the
machine. This unit should be mounted in the tractor cab within in reach and where it can be conveniently viewed by the operator. A suc-
tion pad is supplied with the controller, this should be used mount it (usually to the side window of the cab). The controller’s 12v electrical
supply is connected with a 3 pin euro plug which is compatible with the socket found on most modern tractors. If the tractor does not have
a 3 pin euro socket then one should be tted with the power cables going straight to the battery. The controller is protected from electri-
cal overload with two 15amp fuses in an enclosure on the power cable. The controller is connected to the communication cable from the
machine with a 24 pin connector. Take care when connecting this cable and also ensure that the cables is not under strain and will not be
damaged by sharp edges or the movement of the machine.
The controller is not waterproof so it should be protected from rain and stored indoors when not in use.

Support Rollers
To allow for stability of the bale during the wrapping process the support rollers can be adjusted
dierent sized bales. It is important that the support rollers are adjusted so that the bale is in the
middle of the table. When the bale is on the table (See Fig. 6.9) the distance between the ends of the
bale and the support rollers (D) should be <50mm.
Support Roller Adjustment (See Fig. 6.10)
The support rollers have three adjustment positions (3). In order to move the support roller (1) disconnect
the locking bolt (2) from its original position and move the roller to adjust to distance D. Once the roller is
in its desired position x it in place with the locking bolt (2).
