Furthermore, since the shredded roll bale formed by this shredded roll baler is formed by roll molding the material shredded to about 2 cm or less, it can be fed as it is if it is disassembled. It is expected to greatly contribute to labor saving of feeding work.

The present inventors conducted a questionnaire survey on the dairy farmers in the suburbs about the actual use of this shredded roll bale (especially dismantling and feeding), and it was complicated to remove the binding net and wrap film during dismantling work. In addition, there are many problems that the binding net and wrap film that remain without being removed may be cut into fine pieces, and the binding net or wrap film that has become finer may be mixed into the silage, and it takes time and effort to remove it. I understood.
That is, the shredded roll bale is smaller than the conventional grass roll bale (90 cm in diameter, about 90 cm in height, and a bundling net bundling type), and has a characteristic that it easily breaks once the wrap film and the bundling net are cut. For this reason, it is difficult to remove the wrap film and the binding net at the time of dismantling work, and the silage handling work after dismantling is a heavy labor.
Furthermore, there is a demand for an inexpensive device that can be used for disassembling a shredded roll bale by using a general-purpose mechanical device or the like instead of an expensive dedicated mechanical device.
