Abstract
The material moving blade has a moldboard assembly with a lower moldboard portion and an upper moldboard portion. A hinge connects the upper moldboard portion to the lower moldboard portion for pivotal movement about a horizontal axis. An upper cutting bar with an upper bar working edge is clamped to a top edge of the upper moldboard portion. A lower cutting bar with a lower bar working edge is clamped to a bottom edge of the lower moldboard portion. An actuator pivots the upper moldboard portion about the horizontal axis in one direction to a position in which the upper cutting bar is above the lower moldboard portion and in another direction to a position in which the upper bar working edge is below the lower bar working edge and the upper moldboard material contact surface faces rearward.
