Abstract
A sectional rate control unit for an agricultural implement is disclosed herein. The sectional rate control unit is preferably used with a planting system including a planting implement coupled to a work vehicle. The implement includes a frame having at least one section supporting multiple row units which are configured to apply a product (e.g., seed, fertilizer, insecticide, herbicide) to the rows in a field. Each section includes a product delivery apparatus having a target delivery rate controlled by a section application control signal and at least one product channel for delivering an amount of the product to each of the row units. The control unit includes an electronic product sensor coupled to each of the sections and the product channel. The product sensor is configured to generate a product rate signal representative of the amount of the product delivered to the row units. An electronic display located in the cab is configured to generate an image in response to a display signal. The display includes operator-actuatable switches configured to independently control the state of each of the sections and the target delivery rate of each product for each of the sections. A processor circuit is configured to monitor the product rate signal from each product sensor, to calculate product rate data for each product sensor, to generate and apply a display signal to the electronic display to generate the image on the display representing the product rate data for each product in each section, and to generate and apply the section application control signal to each product delivery apparatus in response to actuations of the switches on the electronic display.
