Abstract
A track chain assembly includes a track pin, a first link, and a second link. The first link defines a first pair of pin passages in spaced relationship to each other by a first link pitch. The first link is mounted to the track pin such that the track pin extends through one of the first pair of pin passages. The second link defines a second pair of pin passages in spaced relationship to each other by a second link pitch. The second link is mounted to the track pin such that the track pin extends through one of the second pair of pin passages and such that the first link and the second link are rotatable with respect to each other about a longitudinal axis defined by the track pin. The second link pitch is greater than the first link pitch in a range up to twice the first link pitch.
