The systems and methods described herein adjust harvest characteristics by selecting one or more harvest characteristics according to the location of a harvester within a field. For example, the selection includes determining the location of the harvester within the field, associating the location with a corresponding zone of a plurality of zones in the field where each of the plurality of zones corresponds to a respective crop planted within the field (for instance a hybrid type), and assigning one or more harvest characteristics to a harvest operation according to at least the corresponding zone and the respective crop within the corresponding zone. Harvest operations are conducted with the assigned one or more harvest characteristics. The systems and methods described repeat selecting the one or more harvest characteristics as the harvester changes location within the field according to further examples.
