Abstract: A monitor for use in a multi-row seed planting apparatus is provided for detecting seeds passing from a seed bin to a plurality of seed dispensers and for indicating by row number an improperly operating dispenser. A seed sensor is placed in the seed flow path of each dispenser to provide an output signal indicating that seeds are continuously flowing along the seed flow path through the dispenser. A two-digit seven-segment readout display is provided on the monitor and is coupled to the seed dispenser through logic circuitry which energizes the readout display to indicate the row number of an improperly operating seed dispenser.
