An adapter board has an upper moldboard interfacing portion including a rear flat surface, a front surface, and a plurality of retaining spring clip receiving apertures extending from the front surface to the rear flat surface. A lower tool bit attachment portion of the adapter board terminates in a lower adapter board free end defining a bottom surface that defines a plurality of shank receiving bores. Each one of the plurality of shank receiving bores is in communication with one of the plurality of retaining spring clip receiving apertures.

Tip for a ground engaging machine implement

A tapered bushing includes a conical inner surface defining a conical axis, and a radial direction. The tapered bushing further includes an outer surface of revolution, and defines a minimum radial wall thickness that ranges from 3.0 mm to 15.0 mm measured from the conical inner surface to the outer surface of revolution. Also, the conical inner surface defines a draft angle that ranges from 2.0 degrees to 30.0 degrees.

Adapter board having a tool bit attachment portion

A spring clip defines an axis of movement, and includes a handle portion disposed at a first end along the axis of movement, and a tool bit engaging portion disposed at a second end along the axis of movement. Also, an adapter board engaging portion is disposed at least partially between the handle portion, and the tool bit engaging portion along the axis of movement.

Front access for bit retention

A wear member includes an attachment portion, and a wear portion extending from the attachment portion that defines a wear surface. The wear portion has a dispersible wear indicator that is disposed in the wear portion, and that is spaced a predetermined distance away from the wear surface.

Dispersible wear indicator

A tool bit includes a working portion, and a shank portion defining a shank free end. The working portion includes a pair of side inserts, and a front insert.

Bucket shroud

In one aspect, a corner shroud includes a body that may have a floor portion having a floor rear surface, a floor inner surface, a floor lower surface, and a floor upper surface having a curved portion, a side portion, extending from the floor portion, and having a side outer surface, a side rear surface, a side inner surface, and a side upper surface, a front portion extending between the floor portion and the side portion, the front portion having a front surface, a front inner surface, and a front rear surface, and a top portion extending from the front portion, the top portion having a top upper surface, a top inner surface, a top lower surface, a top rear surface, and a top outer surface. The floor upper surface, the side inner surface, the front rear surface, the top lower surface, and the top inner surface define a recess.

Corner segment and corner shroud having a curved portion for a work implement

A shroud retention system for a work tool is disclosed. The shroud retention system may have an adapter attached to the work tool. The shroud retention system may also have a shroud that slidably engages with the adapter. The shroud may have a retainer slot. Further, the shroud retention system may have a spring assembly disposed in the shroud. The spring assembly may have a block that slidably moves relative to the adapter. The spring assembly may also have a resilient member disposed between the adapter and the block. In addition, the spring assembly may have a retainer disposed in the retainer slot. The retainer may engage with the block. The retainer may have at least one recess disposed on the retainer front face or on the retainer rear face. The recess may extend partway toward the other of the retainer front face or the retainer rear face.

Shroud retention system for a work tool

A blade assembly includes an adapter board including a lower tool bit attachment portion, terminating in a lower adapter board free end, the lower adapter board free end defining a bottom surface defining a plurality of shank receiving bores. A plurality of bushings are disposed in a corresponding one of the plurality of shank receiving bores.

Adapter board with splined bushing

A wear member comprises a shank portion defining a longitudinal axis, a free end and a perimeter, at least one flat surface on the perimeter extending to the free end and a cross-hole defining a cross-hole axis along which the cross-hole extends through the at least one flat surface perpendicularly, and a wear portion extending downwardly axially from the shank portion, the wear portion including a polygonal configuration.

Serrated blade assembly using differently configured components

An adapter board defines an upper adapter board attachment portion, and a lower tool bit attachment portion. The upper adapter board attachment portion includes a first peak surface and a second peak surface, the first peak surface and the second peak surface forming a first valley between the first peak surface and the second peak surface.

Adapter board bolted joint surface

A work tool or a wear member includes a working portion or a wear portion, and a shank extending from the working portion or the wear portion, defining a longitudinal axis, and a first lock receiving groove that defines an axis of rotation that is perpendicular to the longitudinal axis of the shank.
