A mobile irrigation system including a number of spans, a number of mobile irrigation towers supporting the spans, and a control system. The control system includes a position switch configured to be triggered and transmit a trigger signal and a controller configured to receive the trigger signal from the position switch. Upon receiving the trigger signal, the controller is configured to determine whether a current position of the mobile irrigation system equates to an auto-reverse position. If the current position equates to the auto-reverse position, the controller is configured to transmit a reverse direction signal to a drive motor of one of the mobile irrigation towers to reverse direction so that the drive motor reverses direction.
