Version 1.1
Adapted to patch 1.3.
Unfortunately, I did not get there without adjusting the working width, which is why it looks a bit funny when you plow without helpers. (He plows forward now wider than he is, but inside, so that one does not see it in the helper operation)
He does not drive so far out.
You should only use it with caution if you move the field boundaries or create a new field!
In the helper operation he works again, almost as before.
