Abstract
An agricultural working machine, such as a combine harvester or forage harvester, has a feeding assembly arranged on the front for accommodating a header attachment which is designated to harvest and convey a harvested crop, and at least one gauge wheel attachment comprising at least one support wheel associated with the header attachment on one or both sides of the feeding assembly, wherein the header attachment is arranged pivotally about a rotation axis extending transversely to the longitudinal direction of the agricultural working machine on the feeding assembly in such a manner that the header attachment can be automatically rotated from a working position into a transport position when the feeding assembly is lowered, and at least one support wheel of at least one gauge wheel attachment supports the header attachment on the ground in the transport position. This ensures that the use of a separate header trailer is not necessary. At the same time such a rotating mechanism enables support wheel arrangements to be brought quickly from a working to a non-working position without heavy physical work being required for that alteration.
