Abstract
A global positioning system (GPS) based soil tillage system is disclosed herein. The system includes an agricultural implement such as a plow having electro-hydraulically controlled plow elements which may include plow points, furrowers, ripple coulters, disks, sweeps, tines, etc. The system also includes a control system for monitoring the location of the implement relative to the field, and determining the desired tilling orientation between the plow element and the soil. More specifically, the control system determines the location of the implement based upon a GPS signal, compares the location to a location stored in a data file, and looks up the desired tilling orientation in the data file associated with the location. Based upon the tilling orientation selected from the data file, the control system applies appropriate signals to the electro-hydraulic controls which move the plow elements to the desired orientation. The system can also be used for applications other than tilling where there is an interaction with the soil. For example, control of the depth of ground opening of a seed planting implement may also be provided with the disclosed system.
