Abstract: A work tool assembly includes a work tool lip and a plurality of tip adapters coupled to the work tool lip and each including an upper adapter leg, a lower adapter leg, and a mounting slot receiving a forward lip edge. Each of the upper adapter leg and the lower adapter leg includes a first restraint ledge and a second restraint ledge. The work tool assembly also includes anti-bending stabilizers welded to the work tool lip and each including a hold-down head in contact with one of the first restraint ledge or the second restraint ledge. The anti-bending stabilizers limit bending of the tip adapters by way of reacting bending loads on tooth tips of the work tool lip.

Abstract: A work machine includes a frame, a traction system supporting the frame, an arm assembly having a first end and a second end, the first end connected to the frame, an implement connected to the second end, and a linkage connecting the implement to the second end of the arm assembly. The linkage includes a pin-supporting section configured to accept a pin and a linking section attached to the pin-supporting section by a weld. The linking section includes a recess proximate to the weld.

Abstract: A center pintle hub coupled to a base of a machine is disclosed. The center pintle hub is casted as a single piece. The center pintle hub includes a disc, a hole, a plurality of protrusions, a hollow cylindrical member, and a plurality of stiffening members. The disc couples to the base and includes a first surface and a second surface. The hole extends from the first surface to the second surface, along a central axis of the disc. The plurality of protrusions, disposed on the second surface, is arranged in an array of square configuration. The plurality of protrusions extends from the second surface and attach to a plurality of stiffeners of the base. The hollow cylindrical member is coupled to the first surface and arranged coaxially with the hole of the disc. The plurality of stiffening members is circumferentially disposed and equally spaced around the hollow cylindrical member.
