An agricultural round baler has a press chamber with inlet and rear outlet for ejecting a bale. A pressing device in the press chamber causes the harvested crop to rotate. A pickup device and a conveying and cutting device are provided upstream of a storage chamber that extends to the inlet of the press chamber and receives harvested crop in a storage phase of the baler. An element that interrupts or releases flow of harvested crop from the storage chamber to the press chamber is provided and acted on by a control and governing device. The storage chamber is a flat shaping and pressing channel for the harvested crop conveyed in the storage phase of the baler operation. The channel has a height-adjustable end and a cross-section that at least temporarily in the storage phase tapers in flow direction of harvested crop to the press chamber.
