The forward ends are spread apart and are provided with outwardly and laterally extending bosses having transverse boss pin bores coaxially aligned with each other. The rearward ends are interconnected by a cylindrical barrel having a barrel pin bore extending through each of the sidebars. The sidebars are formed with outwardly and laterally projecting reinforcing ribs-extending between the bosses and the barrel pin bore along a substantial length of the sidebars. A freely rotatable chain pin is inserted through aligned boss and barrel pin bores from either end thereof for interconnecting first and second pairs of sidebars.
