The sliding mechanism enables the first frame section to travel transversely along the tractor and optionally can be retracted so as to enable the first frame section to be situated rearwardly and centrally behind the tractor. The first frame section is designed to accept and maintain a plurality of conventional farming implements, such as toppers, sprayers or the like.
