A seed counter of the present invention is used to accurately count seeds at a high speed. The invention includes a line vac connected to a linear array laser. The line vac is connected to a supply of seeds which are drawn through the line vac by a source of pressurized air and past the photoelectric sensor. The photoelectric sensor is connected to a control circuit which counts the seeds as they pass the photoelectric sensor. The control circuit also controls the flow rate of the counter by means of a variable pressure regulator connected to the line vac. As a result, the flow rate of the counter can be precisely controlled and a precise number of seeds can be counted and conveyed by the invention.
