I can't get the autoload feature to work. Can anyone give instructions on how to do this?

Google Translate:
Ich kann nicht die Autoload-Funktion, um zu arbeiten. Kann jemand Anweisungen, wie dies zu tun?

Hi, great mod man!
One question, can you possibly change the trailer so that it hods 48 square bales? Or maybe a new larger trailer or the old trailer with a hitch. But please don't have single bales on top or cramped in the front, just beautiful stacks. Also the little pillars on the side of the trailer irritate me and i think taking them out would make the look of the trailer better. Plus i think it would be more realistic if the trailer is full that there is a rope securing them in place (or whatever). That would make make the trailer look that much better and all the future trailers too.
Again, great mod mate! Hope you make some more good mods!
Victor
