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.

A plow, including a center blade having a first end and a second end, and a wing blade coupled to each end of the center blade, 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;
- 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;
- 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.
A snow plow comprising:
- a hitch frame nose assembly configured to couple to a vehicle;
- a plow frame coupled to the hitch frame;
- a center blade having a first end and a second end, the center blade being supported by the plow frame;
- a wing blade coupled to each end of the center blade, 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;
- 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 having an edge, wherein the edge of the angled portion of the wearstrip on the center blade and the edge of the angled portion of the wearstrip on the wing blade are aligned with the axis at the first end of the center 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 having an edge, wherein the edge of the angled portion of the wearstrip on the center blade and the edge of the angled portion of the wearstrip on the wing blade are aligned with the axis at the second end of the center blade;
- and
- a wing pivot tube coupled to each of the wing blades and center blade at each end of the center blade about the 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.
A plow, including a center blade having a first end and a second end, and a wing blade coupled to each end of the center blade, with each wing blade pivotally connected to the center blade about an axis and movable through a range of movement between a straight position and a folded position, the plow comprising:
- a wearstrip coupled proximate one end of the center blade, the wearstrip including an angled portion extending therefrom, with an edge of the angled portion aligned perpendicularly with the axis at the one end of the center blade;
- and
- a wearstrip coupled proximate one end of the wing blade, the wearstrip including an angled portion extending therefrom, with an edge of the angled portion aligned perpendicularly with the axis at the one end of the center blade;
- wherein the two angled portion edges are further aligned adjacent to each other and with the axis at the one end of the center blade through the range of movement of the wing blade relative to the center blade.
