The baler (1) has pressing device (18) that is arranged in press chamber (3) to rotate harvested crop. A storage chamber (14) arranged downstream of conveying and cutting device (11) extends to inlet of press chamber. The storage chamber receives harvested crop in storage phase of baler operation of round baler. The pressing channel for harvested crop is conveyed in storage phase of baler operation into storage chamber. A tapering cross-section of channel tapers in flow direction of harvested crop from conveying and cutting device to press chamber. An independent claim is included for method for controlling flow of harvested crop in agricultural round baler.
