ABSTRACT:
A plow, including a center blade and a wing blade coupled to each end of the center blade. Each wing blade is pivotally connected to the center blade about an axis. The plow includes a first pair of wear strips, with one wear strip coupled to the first end of the center blade and the other wear strip coupled to one wing blade. A second pair of wear strips is included, with one wear strip coupled to the second end of the center blade and the other wear strip coupled to the other wing blade. A wing pivot tube is coupled to the wing blades and center blade at each end of the center blade. The wing blade, wear strips, and wing pivot tube at each end of the center blade minimize a gap between the blades throughout the range of movement of each wing blade.
