An apparatus for the unrolling or reduction of cylindrical bales of hay, straw or like material and for the measured distribution of such materials directly to the place of use, comprising, a trolley or trailer capable of being attached to the rear of a tractor and; a substantially horizontal journal or pivot member extending parallel to the forward direction of movement of the trailer and capable of being axially inserted into a cylindrical bale. A mechanism is provided for displacing the pivot member parallel to itself from a lateral, pick-up position to an upper loaded position. The apparatus includes a substantially horizontal conveyor disposed transversely for supporting and unwinding or rotating the cylindrical bale which is loaded thereon and retained by the pivot member. A rotary distributor member provided with projecting teeth or the like is, located near the unloading end of the conveyor, for distributing and laterally directing the material coming from the cylindrical bale which is removed by the conveyor. A driving unit for the actuation of the conveyor and of the distributor member is also provided.
