ABSTRACT:
A drive mechanism for an agricultural planter includes a first electronic controller, a second electronic controller, a hydraulic valve manifold, hydraulic drives for the seed and fertilizer hoppers, and a feedback sensor from the hydraulic drives to the second electronic controller. The first electronic controller is located in the cab of the tractor connected to the planter, while the second electronic controller is mounted on the planter to control the operation of the hydraulic drives. The feedback sensors provide data as to the operation of the hydraulic drives. Another sensor associated with the forward speed of the planter also provides input to the second electronic controller so that the second controller can coordinate the operational speed of the hydraulic drives to provide the rate of application of the seed and fertilizer products desired by the operator. Changes in the rate of application of either the seed or fertilizer materials can be accomplished through input to the first electronic controller.
