Abstract: A shroud for a track shoe grouser protector includes an elongate shroud body having weld holes formed in a first shroud leg and a second shroud leg attached to a base in the elongate shroud body. The shroud may have a fore to aft profile having the form of a flat-crowned arch with the shroud legs flared outward to form a grouser opening for positioning the shroud upon a track shoe grouser in a ground-engaging track system. An inventory of shrouds includes long shrouds and short shrouds positionable in a plurality of different assembly combinations to shield grousers in track shoes having a range of sizes.

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: An articulated chain assembly includes standard links, a master link, and pins pivotably coupling together the standard links and master link. The master link includes a first half link and a second half link, and bolt holes extending through the first half link and the second half link. A first bolt is within a first one of the bolt holes and has a necked-down bolt shank defining a lesser necked-down axial length. A second bolt is within a second one of the bolt holes and includes a necked-down bolt shank defining a greater necked-down axial length. The first bolt and second bolt may have unequal full axial lengths.

Abstract: An idler assembly includes a cylindrical hub defining an axis of rotation, a radial direction, and a circumferential direction. A stepped circumferential surface of the cylindrical hub has a first radially inner face, and a radially outer cylindrical face. Mounting holes extend radially into the radially outer cylindrical face. A first idler segment is attached to the cylindrical hub, and includes an at least partially flat body having a first planar chain link contacting surface. The cylindrical hub has a first set of metallurgical properties that is different than the second set of metallurgical properties of the first idler segment.
