A bushing for a track assembly, according to one or more embodiments, includes: a tubular bushing substrate having a longitudinal length and an outer surface; and at least one white iron member fixed to the outer surface of the tubular bushing substrate.

Track assembly bushing having while iron member

A blade assembly comprises a moldboard defining an upper moldboard free end and a lower moldboard free end, the lower moldboard free end defining a lower curved mounting surface, and an adapter board defining an upper adapter board attachment portion, and a lower tool bit attachment portion. The upper adapter board attachment portion may include a first peak surface and a second peak surface, the first peak surface and the second peak surface forming a first valley therebetween and being configured to contact the lower curved mounting surface.

A wear member for attachment to a surface of a machine is provided, the wear member a body having an outer layer and a base layer. The outer layer including a plurality of channels formed in an outer surface. The base layer is attached to an inner surface of the outer layer. The base layer is divided into a plurality of base layer pieces, each of the plurality of base layer pieces including at least one interfacing edge. The plurality of base layer pieces are assembled together such that each interfacing edge of each of the plurality of base layer pieces is opposite an interfacing edge of another of the plurality of base layer pieces so as to define at least one gap therebetween.

Wear member

A retention system is provided for use in connecting a replaceable tool to a work implement. The retention system may have a generally cylindrical pin with a first hollow end, and a second hollow end located opposite the first hollow end. The retention system may also have a first fastener configured to engage the first hollow end and cause the first hollow end to flare radially outward. The retention system may further have a second fastener configured to engage the second hollow end and cause the second hollow end to flare radially outward.

Retention system having double-ended expandable pin

An eye shield, particularly directed to hair spraying and styling, provides a transparent lens portion fitted with a resilient peripheral seal forming a wall surrounding the eyes and conforming to facial contours so as to effectively protect the eyes from exposure to hair spray or other airborne substances. The shield is fitted with side arms which press inwardly against the temples to hold it in place without interfering with the styling of the hair. The shield provides convenient eye protection suited to many activities involving airborne sprays, including professional hair styling, and is particulary beneficial in enabling a person doing his or her own hair styling to apply hair spray and to simultaneously view the progress of the styling continuously while having full use of both hands for the spraying and styling without risk of eye damage or irritation from the spray.
