First tools such as disk gangs are carried by the secondary support frame, while different type tools such as shank mounted earth working points and contiguous moldboards are mounted on the primary frame spaced from the first tools. Wheels mounted on the primary frame enable raising of the primary and secondary frames and associated tools for transport, and are adjustable to serve as gauge wheels for the earth working points and moldboards.
