An agricultural harvester includes a cutting head configured to harvest an agricultural material, a transfer mechanism configured to transfer the harvested agricultural material from the agricultural harvester, and a fill management system. The fill management system is configured to provide open-loop control of an automated transfer of the agricultural material from the agricultural harvester. The fill management system includes a controller, a user interface module coupled to the controller and configured to receive user input indicative of a selected nudge direction, and a wireless communication module coupled to the fill management system and configured to communicate wirelessly with a receiving vehicle. The wireless communication module is configured to obtain storage dimensions relative to the receiving vehicle from the receiving vehicle. At least one sensor is operably coupled to the transfer mechanism and provides a sensor signal that is indicative of flow of the agricultural material through the transfer mechanism. The controller is configured to automatically generate relative positional adjustments between the agricultural harvester and the receiving vehicle based on the signal indicative of flow through the transfer mechanism and the storage dimensions relative to the receiving vehicle.
