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, preferably a microcomputer device, comprises individual row counters for counting the seeds planted in each row. The monitor determines the row having the highest deviation from the average number of seeds planted per row. Whenever the maximum deviation exceeds a predetermined limit, an alarm signals an error condition to the planter operator. The monitor also senses and warns the operator of any stoppage occurring in any of the rows within a relatively short stoppage distance. Planting data is displayed to the operator during planting.
