摘要

The self-propelled agricultural machine (1) has a traction unit (2) fitted with a steering axle (9). The harvester (3), or other machine, is hooked to the traction unit by a swing coupling assembly (11) in a vertical alignment between the traction unit and the pick-up (5) at the trailer on a vertical swing axis (12). The swing coupling has steering links to the trailer so that it follows the path of the traction unit.
