Abstract
Snowplow blades and cutting edge systems for snowplow blades are described herein. The cutting edge systems include a backing plate coupled to a bottom portion of a moldboard of the snowplow blade and a plurality of cutting edge segments each configured to be slidably mounted to the front surface of the backing plate. The backing plate has, for each of the blade segments, a central opening, a first slot positioned on a first side of the central opening and a second slot positioned on a second side of the central opening. Each cutting edge segment includes a blade segment, a compression member and a retainer plate.

A cutting edge system for a snowplow blade, the system comprising:
- a backing plate coupled to a bottom portion of a moldboard of the snowplow blade;
- and
- a plurality of cutting edge segments each configured to be slidably mounted to a front surface of the backing plate;
- the backing plate having, for each of the cutting edge segments:
- a central opening;
- a first slot positioned on a first side of the central opening;
- and
- a second slot positioned on a second side of the central opening;
- and
- each cutting edge segment comprising:
- a blade segment configured to be slidably mounted to 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 an uppermost edge opposed to the cutting edge and two upwardly extending lobes spaced apart from each other to define an intermediate pocket portion therebetween, each of the two lobes being configured to receive a fastener to slidably mount the blade segment to the backing plate;
- a compression member configured to be retained in between the uppermost edge of the intermediate pocket portion and an engaging surface extending from the central opening 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;
- a retainer plate configured to be slidably 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;
- and
- at least one sleeve positioned rearwardly of the blade segment, each sleeve being configured to receive one of the fasteners, each sleeve being shaped to be received inside one of the slots of the backing plate and slide vertically within the slot when the blade segment moves vertically relative to the backing plate.
