Header securing mechanism for a combine harvester

In a combine harvester, the header is lifted up by the feeder and secured thereto by a mechanism including a pair of securing pins on the feeder's carrier structure. The securing pins are provided with stops protruding towards the header and which include a sloped surface, configured to interact with positioning aids on the header. The lateral outward or inward movement of the securing pins is driven by a centrally placed actuator. As the actuator is extended, the positioning aids roll or glide down the sloped surfaces, enabling a gradual approach of the header towards the feeder, up to a point where the securing pins become aligned with slots on the header. Continued actuation of the pin motion then establishes the securing of the header to the feeder.
