ABSTRACT:
A moldboard structure is movably attached to the lower side of a vehicle frame at its front end or at a midframe location, and extends downwardly toward the ground surface. The moldboard structure has a central point and two lateral extensions with a lower edge. The moldboard extends outwardly and rearwardly from the central point at a sweepback angle of between 10.degree. and 25.degree. and preferably about 17.degree. to the transverse axis. The moldboard extends transversely beyond the centerline of the tire of the immediately rearwardly positioned axle by a distance of at least about 0 to 9". A support affixes the moldboard structure to the frame. The support includes a mechanical linkage operable to move the moldboard between a lowered position wherein the lower edge of the moldboard is at a lowered distance of from about 1 to about 3" from the ground surface, and a raised position wherein the lower edge of the moldboard is at a raised distance from the ground surface that is greater than the lowered distance by about 7 to 11". A drive is operable to controllably move the moldboard between the lowered position and the raised position.
