1. 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) comprising: 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) connected to the first flow path (12) downstream of the primary metering device (16), wherein 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, wherein the feed system (10) further comprises sensor units (30) arranged in at least two ducts (24), the method comprising:
determining (s110) a static pressure in each of the at least two ducts (24) based on signals from the sensor units (30); and
comparing (s120) the determined static pressures to detect whether any of the at least two ducts (24) has a deviating static pressure, indicating an abnormal product flow in said duct (24).
