Abstract: The disclosure relates to a method, performed by a control device (100), for detecting abnormal product flow in an agricultural implement (1) comprising a feed system (10) for an agricultural product (5). The feed system (10) comprises: a first flow path (12); an air flow generating unit (14) arranged in fluid communication with the first flow path (12); a primary metering device (16) arranged to provide the agricultural product (5) to the air flow in the first flow path (12); and at least one distribution unit (20). The at least one distribution unit (20) comprises at least two outlets (22), each connected to a separate duct (24) for conveying the agricultural product (5) to the ground. The feed system (10) comprises sensor units (30) arranged in at least two ducts (24).

Abstract: The present disclosure relates to an agricultural implement (1, 4) comprising a feed system for an agricultural product (5). The feed system comprises a flow path (12); an airflow generating unit (14) arranged in fluid communication with the flow path (12); a at least one metering device arranged to provide the agricultural product (5) to the airflow in the flow path (12); at least one distribution unit (20) connected to the flow path (12) downstream of the at least one metering device, wherein the at least one distribution unit (20) comprises at least one outlet (22); at least one sensor (303) arranged to measure a quantity relating to the flow path (12); and a control unit (200) arranged to control (160) the airflow generating unit (14) to obtain a desired airflow in the flow path (12) based on measurements by the at least one sensor (303). The flow path (12) comprises a measurement part comprising a first part having a first cross section area and a second part having a second cross section area.
