Abstract
A method of controlling a mobile agricultural machine, the method comprising operating a row unit having a ground-engaging element to deliver product to a furrow formed by the row unit, receiving an indication of rotational speed of the ground-engaging element, determining that the rotational speed of the ground-engaging element is below a threshold, and controlling an action of the mobile agricultural machine based on the determination.
Claims19
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.
A method of controlling a mobile agricultural machine, the method comprising:
- operating a row unit having a ground-engaging element to deliver product to a furrow formed by the row unit;
- receiving an indication of rotational speed of the ground-engaging element;
- generating a likelihood that the rotational speed of the ground-engaging element will meet a threshold rotation speed within a time period based on a field condition;
- identifying a predicted plugging condition based on the likelihood;
- and
- controlling an action of the mobile agricultural machine based on the predicted plugging condition.
A mobile agricultural machine comprising:
- a row unit configured to deliver product to a furrow, the row unit comprising a ground-engaging element configured to rotate about an axis of the ground-engaging element;
- and
- a control system configured to:
- receive an indication of rotational speed of the ground-engaging element;
- perform 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, select 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
- control the mobile agricultural machine to perform the machine action.
