1. A method of controlling a mobile agricultural machine, the method comprising:
operating a row unit having a ground-engaging element and configured to deliver product to a furrow formed by the row unit;
receiving an indication of rotational speed of the ground-engaging element;
performing a comparison of the rotational speed of the ground-engaging element to a plurality of rotational speed thresholds, each rotational speed threshold, of the plurality of rotational speed thresholds, having a different associated machine action;
based on the comparison, selecting a machine action that is associated with a particular rotational speed threshold, of the plurality of rotational speed thresholds, that corresponds to the rotational speed of the ground-engaging element; and
controlling the mobile agricultural machine to perform the machine action.
