A baler for forming large cylindrical bales of crop material is equipped with a wrapping mechanism at the rear side of the baling chamber for introducing wrapping material into the baling chamber for wrapping the cylindrical bales. A storage bin for storing extra rolls of wrapping material extends vertically above the wrapping mechanism and contains a plurality of extra rolls of wrapping material. The storage bin is mounted for pivoting about a connection at a lower end region of the bin so that the bin may be lowered to a loading position in which roll compartments of the bin are at a height commensurate with that of the waist of an average adult person standing on the ground so that supply rolls may be easily moved from these compartments to an operating position within the wrapping mechanism and new rolls may be used to replenish the rolls used from these compartments without an operator having to lift the rolls above his or her waist.
