A digging chain is provided with a plurality of trencher or digging teeth mounting brackets at spaced intervals around its periphery. Each mounting bracket is secured to the digging chain by spaced apart adaptor links and pin connections. The mounting bracket includes a base having opposed end surfaces, opposed side surfaces, and a top surface for mounting a trencher or digging tooth cutter bit. A one-piece mounting member is attached to the underside of the base for permitting the base to be securely attached to the upper ends of the adaptor links. The mounting member is generally in the shape of a 'W' in longitudinal cross-section and includes opposed leg portions that are secured to the end surfaces of the base. The upper terminal end of the mounting member's mid-portion is secured to the underside of the base, and the lower end of the mounting member forms a pair of mounting slots or grooves that fit between the opposed, spaced apart adaptor links for attachment thereto. The mounting bracket substantially reduces the number of mounting parts required and is inexpensive to manufacture.
