ABSTRACT:
A system for dispensing multiple types of seed as a planting apparatus (planter or drill) travels throughout an agricultural field is disclosed herein. The planting apparatus is typically an implement having row units for applying seed to the field as the implement is pulled by a vehicle (tractor). The system includes multiple seed bins configured to store multiple types of seed (e.g., multiple crops or varieties). Multiple bins can be formed within a seed hopper by a removable dividing wall. A switch assembly selectively discharges seed from one seed bin in response to control signals generated in a manual or an automatic mode. The control signals are generated using an operator input device in manual mode, and using location signals and a prescription type map in automatic mode. Discharged seed is received by a distribution assembly for delivery to the row units. The distribution assembly preferably includes a seed selector for separating individual seeds, and an air delivery system for delivering the individual seeds to the row units. The seed selector may include a rotatable drum driven by a variable-rate motor. The rotation rate determines the rate at which the seeds are dispensed and is controlled by rate control signals generated using the location signals and a prescription rate map.
