ABSTRACT:
A sidebar is provided for an offset sidebar trenching chain. The sidebar has an inner edge which slides along a boom of a trenching machine, when the trenching chain is in use. The sidebar is induction hardened through a portion thereof extending from the inner edge, for increased resistance to wear due to friction.
