Mod: GPS Mod
There is a technical reason for that, but I decided to live with it. The reason is simple: What you want is a turn outside of the field, but you would do that with lowered and active implements. In reality no farmer would do that. Instead they turn on the headland and make one or two circular passes over the headland afterwards.

If you want to make neat rows with no or little headland I recommend the autoStop-function. This allows you to finish your row exactly, raise your implement, perform your turn manually and probably more precisely than any automatic system, start your next row and hand over to GPS again.
