ABSTRACT OF DISCLOSURE An indicator is provided for indicating rotation of a seed metering shaft used with a grain drill. The present invention incorporates a cylinder mounted to the seed metering shaft with its longitudinal axis offset but parallel to the axis of the shaft. The cylinder is mounted to rotate with the shaft. An indicator arm is hingedly mounted to the frame of the grain drill with one end positioned to ride on the outer surface of the cylinder and the other end free to move in correspondence with movement of the first end. With this invention, the indicator arm moves continually with movement of the seed metering shaft and thus provides a continuous indication of rotation of the seed metering shaft.
