Abstract: A cutting edge system for a snowplow is described. The system includes a backing plate coupled to a moldboard of the snowplow and cutting edge segments mounted to a front of the backing plate. Each cutting edge segment includes a blade segment slidably mounted to the backing plate. Each blade segment has a lower portion, an upper portion having an uppermost edge, and two upwardly extending lobes that define an intermediate portion therebetween. The two lobes each have a slot having a central slot region to receive a fastener and an upper slot region extending between the central slot region and an opening in an upper edge of the lobe. Each cutting edge segment also includes a compression member retained between the uppermost edge of the intermediate portion and an engaging surface of the backing plate to absorb upward movement of the blade segment when the cutting edge engages the ground.

Abstract: A cutting edge system for a snowplow is described herein. The system includes a backing plate coupled to a bottom portion of a moldboard of the snowplow and a plurality of cutting edge segments mounted to a front surface of the backing plate. Each cutting edge segment includes a blade segment slidably mounted to the front surface of the backing plate. Each blade segment has a lower portion configured to engage a ground surface, 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 portion therebetween. Each cutting edge segment also includes a compression member configured to be retained in between the uppermost edge of the intermediate portion and an engaging surface of the backing plate. The compression member is configured to absorb upward movement of the blade segment when the cutting edge engages the ground surface.

Abstract: The coupler is mounted on the end of the boom of a boom-tractor, and provides secure locking-in of a bucket. The coupler having been set to its latched-open condition, the tractor is driven to the bucket so that a bottom-lug of the bucket enters the coupler, whereupon the bucket is picked up and is automatically securely locked into coupler, without any manipulation of the coupler being required of the tractor-driver other than manipulation of the boom. For setting the bucket down on the ground, after use, the driver manually pulls out a slider of the coupler. That action sets the coupler into its slider-held condition, whereby when the tractor is driven away from the bucket, the coupler is automatically left set in the said latched-open condition.
