CONSERVATION TILLAGE IMPLEMENT CONVERTIBLE FOR END TRANSPORT A large tillage implement provided with hinging wing sections is adapted for end towing rather than wing-up folding transport, The hitch which is normally centered at the front of the machine may be swung into a folded condition parallel with the longitudinal axis of the frame and overlying the front portion thereof to protect the hitch coupling to the vehicle outwardly beyond the end of the frame. A front row of tillage shanks can be selectively raised or lowered as desired while leaving the rear row of shanks at their normal elevations for ground working, and a special frame design enables the rear ground wheels of the frame to be positioned in close fore-and-aft proximity to the rear tillage shanks to provide more uniform depth of penetration of the shanks as rises and falls in the ground terrain are encountered. Improved trash flow and reduced trash and residue accumulation are achieved through strategic ground wheel location relative to the tillage shanks and streamlined wheel arm designs associated with the wheel assemblies.
