ABSTRACT:
A monitor is provided for a field planting machine having a plurality of planting units and a plurality of seed sensors respectively associated with the planting units for producing seed signals in response to the dispensing of seeds thereby. The monitor comprises a plurality of sensor circuits coupled in series circuit, one of the sensor circuits being coupled intermediate each of the sensors and a common signal line. These sensor circuits and the associated sensors are sequentially selectable for causing a first condition on the common signal line in response to production of seed signals at or above a predetermined rate and a second condition on the common signal line in response to the non-production of seed signals at or above the predetermined rate.
