1. A draft load control system for an agricultural implement, comprising:
a row unit;
a down force system configured to apply a force within or to the row unit;
a draft load sensor disposed on the row unit and configured to generate a first sensor signal indicative of a draft load on the row unit; and
a controller comprising a memory and a processor, wherein the controller is configured to:
receive the first sensor signal from the draft load sensor indicative of the draft load on the row unit;
determine the draft load on the row unit based on the first sensor signal; and
in response to the draft load exceeding a threshold range, perform a first control operation.
