摘要

The trailer attachment device is for machines, especially for bale presses with a toe bar at its rear end which carries a trailer coupling. The two bar (8) is guided on the machine so that it can move in the machine longitudinal direction (2). On pushing in, it is automatically coupled with the machine by a spring-loaded out hand-released element. A spring-loaded pawl (15) is used as locking mechanism On pushing in the tow bar (8), the pawl slides over a catch cam (11) and when the bar is fully in, it engages behind the cam.
