1. An agricultural system comprising:

  • an agricultural row unit movable on a field between a first soil condition and a second soil condition, the first soil condition having a different soil hardness than the second soil condition;

    a down-pressure actuator applying pressure to the row unit, the down-pressure actuator initially applying a first pressure associated with the first soil condition;

    a soil-hardness sensing device positioned at a distance D forward of the row unit, the soil-hardness sensing device outputting a soil-hardness change signal when detecting a change from the first soil condition to the second soil condition; and

    at least one memory device storing instructions that, when executed by at least one processor, cause the down-pressure actuator to change, in response to receiving the soil-hardness change signal, the first pressure to a second pressure when the row unit encounters the second soil condition.
