A crawler undercarriage configured for modular attachment of work tools wherein the crawler undercarriage operates on at least two endless crawler tracks. Each crawler track extends around and is driven by a crawler sprocket at one extremity of its travel and extending around an idler roller at its other extremity of travel. The crawler undercarriage configured for modular attachment of work tools comprising a longitudinally extending center channel for securing a modular tool. The crawler undercarriage also includes at least one substantially vertical support member extending upwardly from the center channel. The crawler undercarriage also includes at least one mounting bracket secured to extending upwardly from the substantially vertical support member, wherein the modular member is secured to the at least one lower mounting bracket on the substantially vertical support member.
