ABSTRACT:
A seed dispensing hopper having openings in which picker wheels are rotatably disposed. The picker wheels are disposed in a seed bin shaped to direct seed towards the picker wheels. Flexible elements rotate about an axis of the hopper and are aligned over the picker wheels. As the flexible elements rotate, they wipe the sides of the hopper. At the bottom of their rotation, the ends of the flexible elements and the teeth of the picker wheels are moving toward one another. The flexible elements engage the picker wheels as they traverse them, thereby creating an advantageous “spoon-feeding” action which ensures that even sticky or non-flowable seeds can be completely emptied from the hopper.
