A round baler (1) that includes a feed channel (6) leading to a pressing chamber (55), a drivable transfer device (20) to convey harvested material through the feed channel (6) toward the pressing chamber (55) in a pressing mode, as well as a storage device (30) with a storage space (32). There is a means to continuously pick up harvested material, and a storage device (30) has a storage space wall (31) which outwardly delimits the storage space (32), in communication with the feed channel (6) by means of at least one storage space opening (33), as well as a drivable storage space conveyor (34) for the harvested material within the storage space (32), wherein, in storage mode, the storage device (30) intakes harvested material from the feed channel (6) and, in the pressing mode, discharges harvested material to the feed channel (6) both with a storage space opening(s) (33).

An accumulator includes an enclosure, an inlet, an outlet, at least one roller, and a cotton compress assembly. The cotton compress assembly includes a first auger coupled to the enclosure. The first auger has a first shaft and a flighting attached to the first shaft. The flighting is positioned within the enclosure. The first auger compresses the cotton when the first auger rotates around a first axis.
