A plurality of conventional grain drills or other agricultural implements are arranged in a staggered transverse pattern within individual peripheral frameworks. The frameworks are pivoted to one another about longitudinal axes. They are adjustably supported for rolling ground engagement by hydraulically controlled wheel assemblies. Separate hitch tongues are provided at the center of the arrangement for field use, and at one end of the arrangment for travel purposes. The wheels on the framework are adapted to assist in supporting the conventional implements during field use, and are arranged transversely to support the implements in an elevated condition during road travel. A provision is made for use of a single implement with minimum disruption of hitch combination.
