5. Bale Wrapping
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 hydraulic 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 sufficiently 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 layers 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.
