The revolving unwinder for feedbox unloading SBI Bicieffe models can contain hay, straw or partially dried bales of a 120cm base. On request they could be equipped by different kind of chains depending on the use. The cheapest models with the truck included use the hydraulic couplings of the tractor with a two-lever distributor on board in order to adjust the machine itself allowing the unwinding. They could be equipped by an independent box and loading fork. 
We produce also models without the truck with attachment to the lifting, with telescopic attachment, frontal loader or electric fixed models.
