A method for operating a self-propelled agricultural harvester with a cutting unit and a self-propelled agricultural harvester are disclosed. A driver assistance system associated with the agricultural harvester includes a memory that saves data and a computing unit for processing data saved in the memory. The driver assistance system and the cutting unit form an automated cutting unit. A harvesting process strategy is selected from a plurality of harvesting process strategies saved in the memory and at least one cutting unit parameter is selected. The at least one cutting unit parameter may be determined autonomously by the computing unit to implement the at least one selected harvesting process strategy and may be specified to the cutting unit. While the automated cutting unit is being controlled according to the selected harvesting process strategy, responsive to detecting a harvesting process situation on a field to be worked, with the harvesting process situation indicative of deviating from the at least one harvesting process strategy, regulation sequences, which temporarily override the execution of the harvesting process strategy, are executed.
