A system for detecting the levelness of ground engaging tools (46, 50) of a tillage implement, the system comprising: an agricultural implement including a frame and a plurality of ground engaging tools (46, 50) supported relative to the frame; characterized in that the system further comprises: a first sensor (60,62) coupled to the frame, the first sensor configured to capture data indicative of a material flow past at least one first ground engaging tool (46,50) of the plurality ground engaging tools; a second sensor (60, 62) coupled to the frame, the second sensor configured to capture data indicative of a material flow past at least one second ground engaging tool (46,50) of the plurality ground engaging tools; and a controller configured to monitor data received from the first sensor (60,62) and the second sensor (60,62) and compare at least one first monitored value associated with the material flow past the at least one first ground engaging tool (46,50) to at least one second monitored value associated with the material flow past the at least one second ground engaging tool (46,50), the controller being configured to identify that at least a portion of the ground engaging tools (46,50) are not level when the at least one first monitored value differs from the at least one second monitored value by a predetermined threshold value. an agricultural implement including a frame and a plurality of ground engaging tools (46, 50) supported relative to the frame; characterized in that the system further comprises: a first sensor (60,62) coupled to the frame, the first sensor configured to capture data indicative of a material flow past at least one first ground engaging tool (46,50) of the plurality ground engaging tools; a second sensor (60, 62) coupled to the frame, the second sensor configured to capture data indicative of a material flow past at least one second ground engaging tool (46,50) of the plurality ground engaging tools; and a controller configured to monitor data received from the first sensor (60,62) and the second sensor (60,62) and compare at least one first monitored value associated with the material flow past the at least one first ground engaging tool (46,50) to at least one second monitored value associated with the material flow past the at least one second ground engaging tool (46,50), the controller being configured to identify that at least a portion of the ground engaging tools (46,50) are not level when the at least one first monitored value differs from the at least one second monitored value by a predetermined threshold value. a first sensor (60,62) coupled to the frame, the first sensor configured to capture data indicative of a material flow past at least one first ground engaging tool (46,50) of the plurality ground engaging tools; a second sensor (60, 62) coupled to the frame, the second sensor configured to capture data indicative of a material flow past at least one second ground engaging tool (46,50) of the plurality ground engaging tools; and a controller configured to monitor data received from the first sensor (60,62) and the second sensor (60,62) and compare at least one first monitored value associated with the material flow past the at least one first ground engaging tool (46,50) to at least one second monitored value associated with the material flow past the at least one second ground engaging tool (46,50), the controller being configured to identify that at least a portion of the ground engaging tools (46,50) are not level when the at least one first monitored value differs from the at least one second monitored value by a predetermined threshold value.
