In a steering method for an agricultural machine, the agricultural machine is steered by track steering action independent of GNSS position data along an initial travel track in a working region until a headland adjoining the working region is reached at an exit point of the initial travel track. The agricultural machine is automatically steered by turn steering action, steering it based on an actual position determined based exclusively on GNSS position data, through the headland until an entry point of a target travel track in the working region is reached. The agricultural machine is steered by track steering action along the target travel track. The agricultural machine automatically detects a transition from a travel track of the working region into the headland and/or a transition from the headland into a travel track of the working region and switches accordingly between turn steering action and track steering action.
