Abstract: A ground-engaging track includes a track chain formed of standard links and at least one master link. The master link include a first half link and a second half link, clamped together by way of a forward bolt and a rearward bolt. Clamping surfaces of the first half link and the second half link form a first tooth set and a second tooth set, respectively, which may include a total of 2 or 3 full teeth and tooth roots, confined in distribution between a forward bolt hole and a rearward bolt hole.

Abstract: A track roller includes a body having a revolved configuration defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation. A first axial extremity and a second axial extremity are disposed along the axis of rotation. The body of revolution further includes a first rim portion disposed proximate to the first axial extremity, and a second rim portion disposed proximate to the second axial extremity. An outboard track contact surface is disposed axially proximate to the first rim portion, and an inboard slot is disposed axially proximate to the second rim portion.
