Filed:

Sep 23, 1997

Appl. No.:

8/935406

Inventors:

David D. Flamme - Hinsdale IL
Abraham Orbach - Naperville IL
Paul W. Haack - Crystal Lake IL
Eric D. Jacobson - Downers Grove IL

Assignee:

Case Corporation - Racine WI

International Classification:

G06F16500
G05B 1500
B65D 8306

US Classification:

111177

Abstract:

A control system for agricultural implements such as planters, conventional or air drills is disclosed herein. The implement has a frame with multiple sections and each section has a plurality of row units to apply product to multiple rows in a field. The implement is equipped with global output devices (e. g. , lights, actuators for moving moveable frame members, actuators for moving markers) to perform global implement functions in response to global control signals. Each section includes one or more local product metering devices for applying products at varying rates in response to local control signals. The products include seed, fertilizer, insecticide and herbicide. The control system includes command sources (e. g. , a lighting connector; an operator interface in the cab) to generate global commands for the global implement functions and to generate local rate commands for the metering devices. The control system further includes a global controller, and local controllers corresponding to the sections.

US Classification:

111170

Abstract:

A control system for agricultural implements such as planters, conventional or air drills is disclosed herein. The implement includes a frame with one or more sections. Each section supports a plurality of row units configured to apply a product at variable rates to rows in a field. The products can include seeds, fertilizers, insecticides and herbicides. In one configuration, the control system monitors the rates at which the product is applied to the rows. This configuration of the control system includes sensors configured to sense the rates at which product is applied, and a control module configured to monitor the sensed rates and generate a multiplexed output signal representative thereof. The output signal is used, for example, by a cab-mounted display or recording device. The control system, however, can be reconfigured to both monitor and control the application rates by installing a second control module on the frame.

Abstract:

A directional control system for an off-highway implement including a self-propelled engine with a transmission assembly connected thereto for operation in a multitude of speed ranges. The directional control system includes an electrical power source, and a directional selector that is movable to any of three different positions corresponding to forward, neutral, and reverse modes of operation for the implement. The directional control system includes a controller having forward and reverse actuators for conditioning the transmission assembly for operation in forward and reverse modes. The controller is also capable of conditioning the transmission assembly for operation in a neutral mode. An electrical system is connected between the power source and the controller for deriving the control signals used to condition the implement. The electrical system includes a sensor assembly for monitoring the position of the directional selector and for applying control signals to the controller as a function of the position of the directional selector.
