A debris ejector attached to the hub-facing surface of the rim of a tracked work vehicle. The debris ejector has a leading face that is shaped so to slope from a base adjacent the hub-facing surface towards a ridge of the debris ejector and also slant from an inner end of the debris ejector adjacent the inner edge of the rim to an outer end adjacent the outer edge of the rim such that the shape of the leading face redirects debris so that the debris moves away from the hub-facing surface and away from the disk as the wheel rotates.

A track link rail surface and roller interface includes a first roller including a cylindrical configuration defining a radial direction, a longitudinal axis, a circumferential direction, and a plane containing the radial direction and the longitudinal axis. The first roller includes a first track link rail engaging surface including a first concave arcuate surface defining a first concave radius of curvature. The interface includes a first track link including a first track link rail surface including a first convex arcuate surface defining a first convex radius of curvature that is less or equal to the first concave radius of curvature.

An undercarriage configured to support a track chain and to be attached to a machine with an endless track drive includes a first carrier plate attached to the undercarriage, the first carrier plate including a material having a hardness of at least 45 Rockwell Scale C or greater.

A drive component is disclosed. The drive component may include a base of a first material having a first hardness and a plurality of wear inserts of a second material having a second hardness greater than the first hardness. The plurality of wear inserts may extend from an interior of the base to an exterior surface of the base. The base and the plurality of wear inserts may be a composite casting.

A track link for a ground-engaging track system includes an elongate link body having an upper rail surface located in part upon each of a first link strap, a second link strap, and a middle section of the track link. The upper rail surface is formed by a wear band of sacrificial wear material having a hardness that is varied lengthwise along the upper rail surface to retard scalloping of the track link during service and forming relatively softer zones in the first and second link straps and a relatively harder zone within the middle section. Methodology for making such a track link is also disclosed.

A track joint assembly includes adjacent first and second track links each having an elongate link body with an upper rail surface located in part upon first and second link body ends and in part upon a middle section of the link. The upper rail surface forms part of a track rail having a segment formed by each of the middle sections of the elongate link bodies of the first and second track links and a compound segment formed by the two adjacent track links. The upper rail surface is formed of a sacrificial wear material that has a varying cross-sectional area structured to limit scalloping of the track links

A radio-controlled vehicle having a frame, a left undercarriage and a right undercarriage; wherein the frame has a front guide and a rear guide, each configured to house a respective cylinder; each undercarriage having a front slide and a rear slide, which are connected in a sliding manner to the front guide and to the rear guide, respectively; wherein each cylinder is configured to selectively vary the distance between the longitudinal axis of the frame and the longitudinal axis of each undercarriage; wherein each undercarriage comprises an anti-derailment plate.

A track shoe cover is disclosed. The track shoe cover may include a roller engaging surface, and a shoe engaging surface. The shoe engaging surface may comprise a shoe engaging recess defined on at least two opposite sides by a set of side walls, and a respective attachment groove included in the set of side walls. The respective attachment groove may be configured to facilitate mechanical connection of the track shoe cover and a crawler shoe.

A crawler track includes a link and is driven in a direction of travel by a sprocket having a plurality of teeth. The link includes a pad, a first grouser, and a second grouser. The pad defines a first surface, a second surface opposite the first surface, a first end, and a second end spaced apart from the first end along the direction of travel. The pad defines at least one opening extending through the pad between the first surface and the second surface, and the opening is operable to receive a sprocket tooth. The first grouser is positioned on the first surface proximate the first end of the pad, while the second grouser is positioned on the first surface proximate the second end of the pad. The first grouser and the second grouser extend in a direction substantially perpendicular to the direction of travel of the track.

A drive system for a net cleaner to produce efficient propulsion without damage to the cage net. The drive system includes flexible engagement stumps protruding from a base of a driving belt with tips or studs mounted on an end of the stumps. The tips or studs engage the net and propel the net cleaner. The stumps flex to insure that. if excessive pressure is applied to a stud, the stump will bend and the net will release without damage. A guard prevents the stump from directly engaging a cage net. A track belt produces efficient propulsion without damage to the cage net. The track belt includes flexible engagement stumps protruding from a base of a driving belt with tips or studs mounted on an end of the stumps.
