Abstract

A trencher includes a trencher frame mounting a chain bar in a cantilever manner with a safety guide overlying the chain bar. Both the chain bar and the safety guide are adjustable on the trencher frame between various laterally spaced positions with the safety guide being able to overlie the chain bar in the different laterally spaced positions. The chain bar comprises a mounting stub over which one end of an elongated boom may be inserted. The stub includes a central longitudinal slot for receiving bolts passing through the boom to secure the boom to the slot. The use of a longitudinal slot in the stub allows the height of the stub to be maximized relative to the height of the boom to provide a stronger and more durable mounting for the boom.
