1. A control system for a mobile irrigation system, the mobile irrigation system including a span having a mobile irrigation tower driven by a drive motor, the control system comprising:
a position switch configured to be triggered and transmit a trigger signal;
a controller configured to:
receive the trigger signal from the position switch;
upon receiving the trigger signal, determine whether a current position of the mobile irrigation system equates to an auto-reverse position;
transmit a reverse direction signal to the drive motor representing an instruction to reverse direction if the current position equates to the auto-reverse position so that the drive motor reverses direction,
each of the current position and the auto-reverse position being at least one of an angular position of the span, a distance the span is from the end of a run or the beginning of a run, and a discrete latitude or longitude point,
wherein the auto-reverse position includes a tolerance including at least one of an angular tolerance, a linear tolerance, and a tolerance radius; and
a memory configured to store the tolerance, the controller being further configured to receive an input signal representing a change to the tolerance.
