ABSTRACT:
A tractor drawn tillage implement having a front hood, rippers, a rotary tiller and a row former, conditions tight adobe soil ready for planting in one pass. The front hood, having rock deflectors, protects the operator from airborne objects while containing dust and soil disturbed by the rippers and the tiller. The rippers fracture the soil to aid water and root penetration, to increase water retention of the subsoil and to constrain development of hard pan. The rotatary tiller, driven by an auxiliary power unit and having its axis of rotation at or submerged below the ground surface, mulches the soil and plant residue and aerates the soil commensurate with rearward airborne discharge of the soil. A row former deflects the airborne soil into rows of predetermined height and width ready for planting and provides an air tight shroud to control dust and airborne objects. A tool bar is also incorporated for supporting add ons, such as fertilizers and planters.
