A track chain assembly (17, 77, 277) includes a track pin (190, 290), a first link (35, 90, 91, 281), and a second link (30, 100, 200, 287). The first link (35, 90, 91, 281) defines a first pair of pin passages (150, 152; 291, 292) in spaced relationship to each other by a first link pitch (45, 95). The first link (35, 90, 91, 281) is mounted to the track pin (190, 290) such that the track pin (190, 290) extends through one of the first pair of pin passages (150, 152; 291, 292). The second link (30, 100, 200, 287) defines a second pair of pin passages (180, 182; 297, 298) in spaced relationship to each other by a second link pitch (40, 105, 300). The second link (30, 100, 200, 287) is mounted to the track pin (190, 290) such that the track pin (190, 290) extends through one of the second pair of pin passages (180, 182; 297, 298) and such that the first link (35, 90, 91, 281) and the second link (30, 100, 200, 287) are rotatable with respect to each other about a longitudinal axis (LA) defined by the track pin (190, 290). The second link pitch (40, 105, 300) is greater than the first link pitch (45, 95, 295) in a range up to twice the first link pitch (45, 95, 295).
