Abstract: A plug detection system for an agricultural system includes a controller configured to receive first sensor signals indicative of a set of upstream air pressures. The controller is configured to receive second sensor signals indicative of a set of downstream air pressures. The controller is configured to determine a downstream pressure variance based on the set of downstream air pressures. The controller is configured to determine a set of pressure drops based on the set of upstream air pressures and the set of downstream air pressures, and the controller is configured to determine a pressure drop variance based on the set of pressure drops. The controller is configured to determine a variance delta based on the pressure drop variance and the downstream pressure variance, and the controller is configured to identify an impending plugging condition in response to determining the variance delta is greater than a threshold value.

Abstract: A near-plug monitoring system includes particle flow rate sensors coupled to or downstream of a distribution header, wherein the distribution header is coupled to a primary distribution line and a plurality of secondary distribution lines, the distribution header is configured to receive a flow of a granular product from the primary distribution line and to divert the flow of the granular product among the secondary distribution lines. The system includes a controller configured to receive feedback from the particle flow rate sensors, to determine a real-time flow rate of the granular product in the secondary distribution lines, to determine if a near-plug condition is occurring in at least one secondary distribution line based on the real-time flow rate, and to automatically provide a control signal to alter one or more operating parameters of the pneumatic conveyance system when the near-plug condition is occurring to resolve the near-plug condition.

Abstract: A system for determining field plantability during performance of a seed-planting operation with a seed-planting implement includes a soil moisture sensor configured to generate data indicative of a soil moisture content of a portion of the field. In this respect, a computing system is configured to determine a soil moisture content value of the portion of the field based on the data generated by the soil moisture sensor. Additionally, the computing system is configured to receive an input indicative of a soil composition parameter of the portion of the field and determine a soil composition parameter value of the portion of the field based on the received input. Moreover, the computing system is configured to determine a plantability index value for the portion of the field based on the determined soil moisture content value and the determined soil composition parameter value.

Abstract: A control system for multiple row units of an agricultural implement includes a controller configured to selectively enable automatic downforce control for at least one controllable ground-engaging tool of each row unit that is within a work zone of an agricultural field. The automatic downforce control for the at least one controllable ground-engaging tool includes controlling a downforce of the at least one controllable ground-engaging tool such that the downforce is within a threshold range of a respective target downforce. In addition, the controller is configured to selectively disable the automatic downforce control for the at least one controllable ground-engaging tool of each row unit that is within a no-work zone of the agricultural field, or selectively adjust the respective target downforce for the at least one controllable ground-engaging tool of each row unit that is within the no-work zone of the agricultural field.

Abstract: A row unit of a seeder includes a frame configured to be coupled to a toolbar of the seeder. The row unit also includes a single opener pivotally or rotatably coupled to the frame. The row unit further includes a row cleaner assembly that has a row cleaner arm pivotally coupled to the frame or to the single opener and a row cleaner blade rotatably coupled to the row cleaner arm. The row cleaner arm positions a respective rotational axis of the row cleaner blade forward of the single opener relative to a direction of travel of the row unit. A row cleaner actuator is coupled to the row cleaner arm, and the row cleaner actuator is configured to control a first downforce applied by the row cleaner blade to soil.

Abstract: A method of manufacturing a meter roller for an agricultural metering system includes stretching a sealing ring. The method also includes disposing the sealing ring between a first ring of a spindle and a second ring of the spindle. The first ring and the second ring are rigidly coupled to a driven shaft of the spindle, and the driven shaft is configured to engage a drive shaft to facilitate rotation of the spindle. In addition, the method includes enabling the sealing ring to contract such that an outer diameter of the sealing ring is less than or equal to an outer diameter of the first ring and an outer diameter of the second ring.
