How could i messs it up.... Drawbar !?! its so uncommon here i didnt even think about it. Last time seens some of these in person was 20 years ago in the JD plant Mannhein on export units 
As others already stated most common here is the hitch from pic 1 with the lift from pic 3.
What you are looking for is called Zugpendel in German, a few ones even listed now, the pro's here could tell which ones from other models could fit. You might need more parts than shown in pic 2, could be that there are additional mounts under the gearbox.
E.g. https://www.kleinanzeigen.de/s-fendt.-zugpendel/k0
Maybe alwo worth to contact the known german companies which are selling used parts, they might not list these parts as the demand here is near zero
