An excavating machine includes a main frame, an endless digging chain, and a boom. The boom is mounted to the main frame and is adapted to carry the digging chain. The boom includes an upper surface, a lower surface, an inner end and outer end. The surfaces are adapted to slidably engage the chain. A drive sprocket is mounted to the main frame and is disposed at the inner end of the boom for engaging the chain. A wear plate is mounted to the boom and is disposed between the drive sprocket and the inner end of the boom for slidably engaging the chain between the drive sprocket and the upper surface of the boom inner end.
