A continuous-operation baler assembly is provided which includes a separate and leading surge bin followed by a baler. The surge bin and baler each comprise a separate pick up mechanism for collecting agricultural material. When the baler has collected material and is ready to finish a bale the surge bin receives a signal and begins collecting agricultural material. Once the bale nears finish, the material collected by the surge bin is metered out into the path of or otherwise transferred to the baler during the next bale formation cycle, where it is picked up and formed into a bale.
