Snowplow with ground contour following cutting edge and impact absorption

A cutting edge segment configured to be mounted to a front surface of a backing plate of a snowplow, the cutting edge segment comprising:

• a blade segment configured to be slidably mounted to the front surface of the backing plate, the blade segment having:
• a lower portion having a cutting edge configured to engage a ground surface, and
• an upper portion having two upwardly extending lobes spaced apart from each other to define an intermediate portion therebetween, the lobes and the intermediate portion forming a pocket, each of the two lobes having a slot configured to receive a fastener to slidably mount the blade segment to the backing plate;
• a compression member shaped to fit within the pocket and to be retained in between an uppermost edge of the intermediate portion and an engaging surface of the backing plate, the compression member being configured to absorb upward movement of the blade segment when the cutting edge engages the ground surface;
• and
• a retainer plate configured to be mounted to the backing plate and cover at least a portion of the blade segment when the blade segment is mounted to the backing plate.

A snowplow comprising:

• a moldboard;
• a backing plate coupled to a bottom portion of the moldboard;
• and
• a plurality of cutting edge segments configured to be mounted to the front surface of the backing plate, each cutting edge segment comprising:
• a blade segment configured to be slidably mounted to the front surface of the backing plate, the blade segment having:
• a lower portion having a cutting edge configured to engage a ground surface, and
• an upper portion having two upwardly extending lobes spaced apart from each other to define an intermediate portion therebetween, the lobes and the intermediate portion forming a pocket, each of the two lobes having a slot configured to receive a fastener to slidably mount the blade segment to the backing plate;
• a compression member shaped to fit within the pocket and to be retained in between an uppermost edge of the intermediate portion and an engaging surface of the backing plate, the compression member being configured to absorb upward movement of the blade segment when the cutting edge engages the ground surface;
• and
• a retainer plate configured to be mounted to the backing plate and cover at least a portion of the blade segment when the blade segment is mounted to the backing plate.
