Abstract: An attachment for a conventional, walk-behind power tiller for forming seed rows and adjacent furrows wherein an auger disposed perpendicularly to the seed row being formed has a larger diameter at its proximal ends and a smaller diameter at its central, inner end. The auger is rotated using power derived from the tiller to which the novel seed row forming apparatus is attached. In operation, the larger diameter outer portions of the auger dig a furrow and move the disturbed soil inwardly along the diminishing diameter of the auger, thereby depositing the soil from each side of the auger into a central berm or seed row. The apparatus provides seed row-forming capability for use with small rotary tillers and provides minimum soil tillage while readily forming planting rows.

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.

Abstract: A cultivating machine has an elongated cultivating member that is rotatably mounted to turn about a horizontal axis that extends transverse to the direction of normal travel. A plurality of tined soil cultivating means is mounted on a support shaft of the member and that shaft defines the horizontal axis of rotation. Each cultivating means comprises a group of tines that is freely rotatable about a corresponding axis of rotation.

The soil working members can be tines or blades that are positioned to enter the soil in unison, lift sliced portions of soil and deposit same on the ground to the rear of the plow. The soil working members are mounted in offset relationship at locations about the axis of rotation to minimize "drag and snatch." The soil working members can be turned in addition to being revolved about the axis of rotation as a part of a rotor and more than one row of soil working members can be mounted on the implement. Scrapers, stationary or movable, can be positioned to cooperate with the soil working members to shed the soil from these members.
