Abstract: A system for measuring crop seed rate of a planting machine, the system including a camera having a first field of view through which crop material may pass, and one or more electronic controllers in operable communication with the camera and the planting machine. The one or more electronic controls are configured to receive image data from the camera, identify one or more attributes of the crop material positioned in the field of view of the camera, determine a speed associated with the planting machine, determine a current crop seed rate of the planting machine based at least in part on the one or more attributes of the crop material in the field of view and the speed of the planting machine, and output one or more recommended operating conditions to the planting machine based at least in part on the determined crop seed rate.

Abstract: A harvester includes a separator configured to separate a cut crop into a billet material and extraneous plant matter, a billet loss sensor configured to generate a first signal indicative of the amount of billet material that is lost and unharvested at the separator; a trash sensor configured to generate a second signal indicative of the amount of the extraneous plant matter that is harvested from the separator, and a control unit configured to, based at least partly on the first signal and the second signal, determine a preferred ground speed of the harvester and/or a preferred separator speed of the harvester.
