A shroud retention system may include a retainer plate holder having a top surface, a bottom surface parallel to the top surface, a retainer plate engaging surface extending between the bottom surface and the top surface, wherein the retainer plate engaging surface may be inclined relative to a plane perpendicular to the top surface, a rear surface opposite the retainer plate engaging surface, a through-hole intersecting the retainer plate engaging surface and the rear surface and one or more protrusions extending from the retainer plate engaging surface.

Holder for a work tool

A wing shroud has a body including a side portion having a side inner surface, a side abutment surface, a side outer surface, and a side rear surface, a floor portion having a floor upper surface, a floor lower surface, a floor front surface, a floor outer surface, and a floor rear surface, and an attachment recess defined by a plurality of inward surfaces on the side and floor portions. The body also has a leading edge extending between the side inner surface, the side outer surface, the floor front surface, the floor upper surface, and the floor outer surface, and including an upper end, a transition portion, a lower curved portion, and a lower end.

Wing shroud

A base includes a male portion including a first projection, and a second projection facing in a diametrically opposed manner to the first projection. A stepped bore extends from the first projection to the second projection that has a large diameter portion that is at least partially formed by the first projection.

Adapter with thru-hole and rail

A wear member includes a body having a forward closed portion, and a rear open portion defining a cavity. The wear member also includes an exterior surface, an interior surface defining the cavity, and a retaining mechanism receiving aperture. The retaining mechanism receiving aperture includes an interior portion defined by the interior surface, an exterior portion defined by the exterior surface, and a ring dividing the interior portion from the exterior portion and defining a thru-slot that is in communication with the interior portion and the exterior portion.

Anti-tipping features for a retaining mechanism

An adapter retention plug includes an elongated body defining a right extremity, and a left extremity disposed along a longitudinal axis. The elongated body also includes a right vertical undercut forming void, a left vertical undercut forming void, and a tab extending along the longitudinal axis defining the right extremity.

A retainer sleeve includes an at least partially annular body defining an axis of rotation, a radial direction, and a circumferential direction. The body may also have a radially inner annular surface defining a radially inner aperture, and a first anti-rotation feature extending radially inwardly from the radially inner annular surface including a sloping ledge having a locking surface that faces at least partially in the circumferential direction and along a direction that is parallel to the axis of rotation, forming an oblique angle with the direction that is parallel to the axis of rotation.

A ground engaging tip of a ground engaging tip assembly includes an adapter configured for attachment to the base edge of the implement and having a forwardly extending adapter nose. The ground engaging tip has a rear edge, a top outer surface, and a bottom outer surface. The top and bottom outer surfaces extend forward from the rear edge and converge at a front edge of the ground engaging tip. The tip has first and second side outer surfaces extending forward from the rear edge of the ground engaging tip to the front edge. The tip has a nose cavity for receiving the adapter nose therein. The tip has a support rib on at least one of the first or second side outer surfaces, the support rib being positioned at the rear edge and extending lengthwise from the bottom outer surface toward the top outer surface.

The top cover defines a first fastener receiving void that is disposed along the direction of material flow between the forward ramp portion and the rear edge. The top male angled surface of the top cover defines a first material flow groove that extends along the direction of material flow, and includes a first flow ramp. The first material flow groove is disposed adjacent along the lateral direction and the direction of material flow to the first fastener receiving void.

Cast top cover for base edge wear protection

A cutting edge tip includes an attachment portion defining an adapter receiving void. A working portion extends forwardly from the attachment portion. A first lateral end portion is disposed along the lateral direction, the first lateral end portion defining a first lateral end surface that jogs laterally. Also, a second lateral end portion is disposed along the lateral direction opposite of the first lateral end portion. The second lateral end portion also defines a second lateral end surface that jogs laterally.

Overlapping cutting edge tip system

An adaptor includes a body defining a longitudinal axis, and a transverse axis that is normal to the longitudinal axis. The body also has a leading portion defining a lock receiving recess extending transversely at least partially through the leading portion, and a wire receiving conduit that is in communication with the lock receiving recess. The lock receiving recess defines a width and a depth with a ratio of the depth to width is greater than 1.0.

Electronically operated locking system for earth moving equipment and method

Each of the plurality of center notches and the first and the second end notches of a base edge includes a different configuration including a different end notch depth along the direction of assembly that is greater than a center notch depth along the direction of assembly.

Work implement assembly using adapters, adapter covers, and a notched base edge

A wear member includes a body defining an exterior with an outside perimeter, an interior aperture with an at least partially interior polygonal perimeter, and at least one fastener receiving hole extending from the exterior to the interior aperture. The exterior lacks any large openings to limit the risk of material packing.

Replaceable wear plate

A tip assembly includes a tip including a body having a narrow tip portion, a broad attachment portion that defines a concave surface, an interior disposed between the broad attachment portion and the narrow tip portion, and a cavity that leads from the concave surface toward the interior. A retention bolt that is heated includes a tapered region, and a shaft extending from the tapered region, terminating at an externally threaded end. The cavity of the tip is at least partially complimentarily shaped to the tapered region of the retention bolt.
