A track chain assembly (100) comprises a plurality of interlocking track chain members (500) wherein each track chain member (500) defines a track chain traveling direction (T), a lateral direction (L) perpendicular to the track chain traveling direction (T), and includes a shoe member (502) defining a shoe width (W502) along the lateral direction (L); and a first track pad member defining a first track pad maximum width along the lateral direction, and a second track pad member defining a second maximum track pad width along the lateral direction, wherein a ratio of either track pad maximum widths to the shoe member width ranges from 1:4 to 3:4.
