Abstract
A pitch plow and a method of controlling an elevation of a cutting edge of a pitch plow having a frame and a shank that is pivotally mounted to the frame, with the shank defining a cutting edge includes a control system that controls an elevation of the cutting edge. The control system includes a hydraulic control between the shank and the frame to pivotally adjust the shank and an electronic control to control the hydraulic actuator. The electronic control includes a processor and first and second sensors. The processor produces an output that adjusts the hydraulic control in a manner that controls the elevation of the cutting edge. The first sensor may measure GNS location and provides a GNS location input to the processor. The second sensor may measure orientation of said shank and provides a shank orientation input to the processor.
