Abstract

A harvesting machine, especially a self-propelled pick-up chopper for picking up and chopping corn, wilted grass, green feed and similar harvested produce, including an ejection elbow arranged after pulling in and chopping devices for transferring harvested produce to a loading space of an accompanying vehicle. In order to free the operator of the harvesting machine from the burden of the cumbersome positioning work after each change in the direction of travel, the ejection elbow can be swiveled by a motor controlled by a control device from a first operating position into a second operating position which corresponds to the first operating position of the ejection elbow mirrored in the vertical median plane.
