A crawler bar of a crawler track of a crawler vehicle is provided, including a linear bar base body and a cutting element. The cutting element contains a plurality of cutting element portions, each including a cutter-connecting member and a cutter. When installed, the crawler bar engages on a driving surface of the vehicle. The cutter-connecting member protrudes from and extends on the bar base body in a longitudinal extension of the bar base body. A main face of a first cutter-connecting member of a first cutting element portion lies in a plane (H1), a main face of a further cutter-connecting member of a further cutting element portion lies in a plane (H2), and the two planes (H1) and (H2) have a single intersection line (S)with each other.

A track assembly mountable to a rotatable rear axle of a vehicle includes a frame, a drive wheel rotationally mounted to the frame and being structured to be attached to the axle of the vehicle, a front idler wheel and a rear idler wheel assemblies mounted to the frame, and a track. The track has an inner surface facing the drive wheel, and an outer surface opposite the inner surface. The outer surface has a plurality of traction lugs distributed along the outer surface. The track includes a plurality of longer transverse reinforcement rods distributed therethrough and a plurality of shorter transverse reinforcement rods distributed therethrough. The shorter transverse reinforcement rods are shorter in length than the longer transverse reinforcement rods. Each of the longer and shorter transverse reinforcement rods is aligned along at least a part of its length with at least one of the traction lugs.

A ground-engaging track system includes a track roller having a roller shell with an outer tread surface, and a roller shaft supporting the roller shell for rotation and cantilevering the track roller to a track roller frame. The track roller is positionable in the track system to contact only one of a first track rail or a second rail in a ground-engaging track.

A ground-engaging track shoe in a track joint assembly includes a shoe plate having bolt holes extending through a middle plate section between a planar link-bolting surface and a ground-contact surface. A weight relief channel is formed in the middle plate section upon a link-bolting side of the track shoe, and extends inwardly from the planar link-bolting surface. The weight relief channel is arranged between a forward bolt hole set of the bolt holes and a back bolt hole set of the bolt holes in a fore-aft direction.
