ABSTRACT OF THE DISCLOSURE A universal digging boom assembly is disclosed for attaching either a conventional type digging chain or a rock type digging chain for trenching operations. The boom assembly includes a box-like core section having upper and lower stiffening strips wherein each stiffening strip includes a plurality of embossments along its longitudinal extent. These embossments form mounting portions between the stiffening strips and the core section so that sprocket assemblies or channels may be attached to the boom assembly depending on the type of digging chain being used. The digging boom also includes an attachment portion which permits the boom to be mounted on the trencher for both center and offset trenching operations. Other features include the sprocket assemblies and a rock chain channel which provide additional ease in the utilization of the various types of digging chains on the boom assembly.
