Agricultural apparatus for sensing and providing feedback of soil property changes in real time
First Claim
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.

Abstract
An agricultural system includes 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 applies an initial first pressure associated with the first soil condition. A soil-hardness sensing device is positioned at a distance D forward of the row unit and outputs a soil-hardness change signal when detecting a change from the first soil condition to the second soil condition. At least one memory device stores 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 initial first pressure to a different second pressure when the row unit encounters the second soil condition.

10. An agricultural system comprising:
-
a towing frame for attachment to a towing vehicle draw bar; an agricultural row unit attached to the towing frame in a trailing position relative to a moving direction on a field, the row unit being movable between a first soil condition and a second soil condition, the first soil condition having a different soil hardness than the second soil condition, the row unit including a down-pressure actuator for 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 unit attached to the towing frame in a forward position relative to the moving direction on the field, the soil-hardness sensing unit being positioned at a distance D forward of the row unit, the soil-hardness sensing unit detecting soil-hardness changes and 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. - View Dependent Claims (11, 12, 13, 14)
