A crop harvesting system (300) for continuous round baling is described that comprises a first and second bale chamber (310, 320) and a conveyor system (330) in operable communication with the first and second bale chambers. The conveyor system transfers harvested material (301) from a harvesting assembly (303) to one of the two bale chambers and assumes a variable geometry to facilitate movement of a bale (B1) still in formation from the first bale chamber to the second bale chamber. The crop harvesting system can comprise at least three bale carriers (350, 370, 380), at least two serpentine systems (340, 360) to facilitate movement of the bale (B1) into and out of the first and second bale chambers. The crop harvesting system can be integrated into an agricultural harvester such as a baler or combine.
