1. A tilt monitoring system for a mobile irrigation system including a span having a mobile irrigation tower driven by a drive motor, the tilt monitoring system comprising:
a sensor configured to:
be mounted on the span,
detect a tilt magnitude of the span, and
generate a tilt signal representative of the tilt magnitude; and
a controller communicatively coupled with the sensor and configured to:
receive the tilt signal representing the tilt magnitude;
determine a tilt event has occurred based on the tilt magnitude;
determine a tilt event type of the tilt event from a plurality of tilt event types according to additional data,
wherein the plurality of tilt event types includes tilt due to climbing a foreign object, tilt due to being stuck in an end of path barrier, tilt due to rut formation, tilt due to failure of at least one of a motor and a drive train, and tilt due to tall crop interference,
wherein the additional data includes at least one of a motor speed, a pump flow rate, and a span alignment;
generate a deactivation signal representing an instruction to deactivate the drive motor if the tilt magnitude is greater than a tilt threshold;
transmit the deactivation signal to the drive motor;
generate a notification signal representing a notification that the drive motor has been deactivated due to the tilt magnitude, the notification including a prompt for a follow-up input; and
transmit the notification signal.
