Hard to beat JD steering on JD machines 

I just got out of the cab of a 9360R that is doing turn automation and it was really smooth in automated turns (and straight on the rows of course) 
But if you hit the engage button doing regular steering after halfway around the turn it would take it in just like you were steering it 

I remember doing an ag leader install long ago and support saying put your seat belt on for the track machine's calibration. They weren't wrong
