A track link (36, 38) for a ground-engaging track comprising: an elongate link body including an inboard link side, an outboard link side, a first link strap having a first track pin bore formed therein and extending between the inboard link side and the outboard link side, a second link strap having a second track pin bore formed therein and extending between the inboard link side and the outboard link side, and a middle section; the elongate link body further having a lower shoe-mounting surface, and an upper rail surface (46, 47); the upper rail surface (46, 47) including a central pad formed on the middle section, a first leg extending from the central pad onto the first link strap, and a second leg extending from the central pad onto the second link strap; the first leg and the second leg are laterally offset from one another in a transverse direction, the track link being characterised in that the middle section of the elongate link body includes an inboard rail protrusion (48, 49), projecting from the inboard link side, and the central pad includes an anti-scalloping bump-out (50, 51) formed on the inboard rail protrusion (48, 49); wherein the upper rail surface (46, 47) includes an outboard edge and an inboard edge, and defines a latitudinal midline extending between the inboard edge and the outboard edge, and the anti-scalloping bump-out (50, 51) extends fore and aft of the latitudinal midline; the upper rail surface (46, 47) has a bumped-out dimension formed by the central pad within the anti-scalloping bump-out (50, 51), and a second dimension formed by the central pad outside of the anti-scalloping bump-out (50, 51), and a ratio of the bumped-out dimension to the second dimension is from 1.2:1 to 1.6:1; a latitudinal first line is defined at a first origin of the anti-scalloping bump-out (50, 51); a latitudinal second line is defined at a second origin of the anti-scalloping bump-out (50, 51); and an anti-scalloping surface area is defined by the central pad as bounded fore-aft by the latitudinal first line and the latitudinal second line. an elongate link body including an inboard link side, an outboard link side, a first link strap having a first track pin bore formed therein and extending between the inboard link side and the outboard link side, a second link strap having a second track pin bore formed therein and extending between the inboard link side and the outboard link side, and a middle section; the elongate link body further having a lower shoe-mounting surface, and an upper rail surface (46, 47); the upper rail surface (46, 47) including a central pad formed on the middle section, a first leg extending from the central pad onto the first link strap, and a second leg extending from the central pad onto the second link strap; the first leg and the second leg are laterally offset from one another in a transverse direction, the track link being characterised in that the middle section of the elongate link body includes an inboard rail protrusion (48, 49), projecting from the inboard link side, and the central pad includes an anti-scalloping bump-out (50, 51) formed on the inboard rail protrusion (48, 49); wherein the upper rail surface (46, 47) includes an outboard edge and an inboard edge, and defines a latitudinal midline extending between the inboard edge and the outboard edge, and the anti-scalloping bump-out (50, 51) extends fore and aft of the latitudinal midline; the upper rail surface (46, 47) has a bumped-out dimension formed by the central pad within the anti-scalloping bump-out (50, 51), and a second dimension formed by the central pad outside of the anti-scalloping bump-out (50, 51), and a ratio of the bumped-out dimension to the second dimension is from 1.2:1 to 1.6:1; a latitudinal first line is defined at a first origin of the anti-scalloping bump-out (50, 51); a latitudinal second line is defined at a second origin of the anti-scalloping bump-out (50, 51); and an anti-scalloping surface area is defined by the central pad as bounded fore-aft by the latitudinal first line and the latitudinal second line.
