Snowplow blade system

A snowplow blade system, comprising:

• a first snowplow blade section, comprising:
• a first base edge;
• and
• at least a first lateral edge, wherein the first lateral edge defines a first interconnect feature, the first interconnect feature comprising a first protrusion and a first recess;
• and
• a second snowplow blade section, comprising:
• a second base edge;
• and
• at least a second lateral edge, wherein the second lateral edge defines a second interconnect feature, the second interconnect feature comprising a second protrusion and a second recess, wherein the first recess is configured to receive the second protrusion, and wherein the second recess is configured to receive the first protrusion.

A method for installing a snowplow blade, comprising:

• mounting a first snowplow blade section to a mounting bracket, the first snowplow blade section comprising:
• a first base edge;
• and
• at least a first lateral edge, wherein the first lateral edge defines a first interconnect feature, the first interconnect feature comprising a first protrusion and a first recess;
• obtaining a second snowplow blade section, the second snowplow blade section comprising:
• a second base edge;
• and
• at least a second lateral edge, wherein the second lateral edge defines a second interconnect feature, the second interconnect feature comprising a second protrusion and a second recess;
• positioning the second snowplow blade section such that (i) the first protrusion of the first snowplow blade section is within the second recess of the second snowplow blade section and (ii) the second protrusion of the second snowplow blade section is within the first recess of the first snowplow blade section;
• and
• mounting the second snowplow blade section to the mounting bracket, wherein engagement between the first interconnect feature of the first snowplow blade section and the second interconnect feature of the second snowplow blade section contributes to positional retention of the second snowplow blade section during mounting of the second snowplow blade section.
