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.
