Abstract
A blade plow preferably formed by three frame sections hingedly coupled together includes a ground or terrain contour following mechanism within each frame section. The contour mechanism allows the middle blade to be raised and lowered to maintain the entire central blade horizontal relative to the plow frame and at a constant depth within the ground. Additional 'fixed' blades are hydraulically setable for depth of cut. The terrain contour following mechanism allows for larger frame widths without the usual tendency of smaller width frames to buckle due to ground unevenness.
