Abstract:
1. A plow, including a center blade having a first end and a second end, the center blade having a plow side and a vehicle side opposite the plow side, and a wing blade coupled to each end of the center blade, each of the wing blades having a plow side and a vehicle side opposite the plow side, with each wing blade pivotally connected to the center blade about an axis located substantially in front of the center blade and movable through a range of movement between a straight position and a folded position, the plow comprising: a first pair of wearstrips, with one wearstrip coupled to the first end of the center blade and the other wearstrip coupled to one wing blade, with each of the first pair of wearstrips including an angled portion extending therefrom and having an edge aligned perpendicularly with the axis at the first end and substantially in front of the center blade, the angled portion of the wearstrip coupled to the one wing blade extending in a direction away from the vehicle side of the one wing blade; a second pair of wearstrips, with one wearstrip coupled to the second end of the center blade and the other wearstrip coupled to the other wing blade, with each of the second pair of wearstrips including an angled portion extending therefrom and having an edge aligned perpendicularly with the axis at the second end of and substantially in front of the center blade, the angled portion of the wearstrip coupled to the other wing blade extending in a direction away from the vehicle side of the other wing blade; and a wing pivot tube coupled to each of the wing blades and center blade at each of the first and second end of the center blade about the respective axis; wherein the orientation of the wing blade, the wearstrips and the angled portions thereof, and the wing pivot tube at each of the first and second ends of the center blade minimize a gap defined between each end of the center blade and the associated wing blade, throughout the range of movement of each wing blade.
