Abstract
A seed planter monitor is used with a traveling seed planter operable to periodically dispense seeds in each of a plurality of rows. The monitor scans the outputs of seed sensors which provide electrical signals as the seeds are dispensed. A detector triggers an alarm in the absence of output signals from an examined seed sensor during a predetermined time period. A visual display identifies the row being examined by the scanner.
