Plow blade

A blade edge for detachably mounting onto an elongated support member having a support member length, the blade edge comprising:

• an edge body having a blade edge length, a blade edge height and a blade edge thickness, wherein the blade edge length is greater than the blade edge height and the blade edge thickness;
• wherein the blade edge length extends in the direction of the support member length when detachably mounted on the support member;
• said blade edge having a lower edge defined by said blade edge length and said blade edge thickness;
• and said lower blade edge having a plurality of insert holes therein distributed along the blade edge length;
• a plurality of blade inserts having a wear portion and being mounted within the plurality of insert holes of the blade edge such that the wear portion protrudes to some extent from the plurality of insert holes and wherein said plurality of blade inserts consists essentially of a cemented metal carbide;
• wherein each of the plurality of blade inserts mounted within the plurality of insert holes are spaced apart so as to be in a non-contacting relationship with any other blade insert mounted within the plurality of insert holes.

A snowplow blade edge, for detachably mounting onto an elongated support member having a support member length, and to be used for removing snow from a surface, the blade edge comprising:

• an edge body having an edge length, an edge height and an edge thickness, wherein the edge length is greater than the edge height and the edge thickness;
• wherein the edge length extends in the direction of the support member length when detachably mounted on the support member;
• said edge having a lower edge defined by said edge length and said edge thickness;
• and said lower edge having insert holes therein distributed all along the edge length;
• a plurality of blade inserts each having a wear portion, the wear portion having a convex curved wear surface, the plurality of blade inserts being held by braze in said insert holes along the lower edge such that the wear portion will contact the surface from which snow is being removed;
• wherein each of the plurality of blade inserts mounted along the lower edge is spaced apart so as to be in a non-contacting relationship with any other blade insert mounted along the lower edge.

A plow blade for removing snow from a surface, the plow blade comprising:

• an elongated support member having a support member length;
• a blade edge detachably mounted to the support member and said blade edge having a blade edge body with a blade edge length, a blade edge height and a blade edge thickness, wherein the blade edge length is greater than the blade edge height and the blade edge thickness;
• wherein the blade edge length extends in the direction of the support member length;
• said blade edge having a lower edge defined by said blade edge length and said blade edge thickness;
• and said lower blade edge having first and second insert holes therein distributed along the blade edge length;
• first and second blade inserts, each having a wear portion and an intermediate portion, the wear portion having a convex curved wear surface, the intermediate portion having a cylindrical configuration adjoining the wear portion and a seating end adjoining the intermediate portion, the first and second blade inserts being brazed into the first and second insert holes along the lower edge such that the wear portion will contact the surface from which the snow is being removed.
