1. A method for adjusting a turning radius of an agricultural vehicle towing trailer, the method comprising:
receiving trailer sensor data indicative of a coupling status of a towing trailer to an agricultural vehicle;
determining that the towing trailer is coupled to the agricultural vehicle based on the received trailer sensor data;
receiving speed sensor data indicative of a rotational speed of a first wheel of the agricultural vehicle and a rotational speed of a second wheel of the agricultural vehicle when determined that the towing trailer is coupled to the agricultural vehicle;
determining a difference between the rotational speed of the first wheel and the rotational speed of the second wheel based on the received speed sensor data;
comparing the determined difference between the rotational speed of the first wheel and the rotational speed of the second wheel to a predetermined threshold, wherein the predetermined threshold is established based on a minimum allowable angle between a direction of motion of the agricultural vehicle and a direction of motion of the towing trailer;
increasing or decreasing the rotational speed of the first wheel or the second wheel if the difference between the rotational speed of the first wheel and the rotational speed of the second wheel exceeds the predetermined threshold; and
initiating a signal to the operator when the determined difference is greater than the predetermined threshold.
