  • Patent number: 5524711
    Abstract: The present invention entails an agricultural implement for forming planting rows with a minimum of tillage. The implement of the present invention is designed to form a multiplicity of rows and accordingly includes a series of side-by-side row units. Each row unit includes a front colter, a ripper which follows the colter, a rotor tiller assembly disposed behind the ripper, a pair of laterally spaced soil confining panels extending between the ripper and the rotor tiller assembly, and a final following soil packer. Once the agricultural implement has traversed a certain area of the land, there is formed a multiplicity of planting rows with the area between the formed planting rows being untilled.

  • Patent number: 4364436
    Abstract: A plow is structured to wholly or partly invert a furrow slice during operation. The furrow slice is cut loose by a leading V-shaped blade and is both compressed, and deflected laterally towards a side wall of the frame by a plurality of rotary lateral displacing rollers arranged in a row inclined to the direction of travel. The rollers are preferably of progressively increasing size towards the rear and co-operate with a soil guide surface at the rear of the plow in turning the furrow slice about an axis which extends in the direction of travel to deposit the slice substantially completely back into the furrow from which it was originally cut. In one version, the row of displacing rollers leads to a power-driven rotary soil guide unit of annular formation, the inverted furrow slice being delivered back into the furrow from which it was cut through the interior of the unit.

  • Patent number: 4331204
    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.

  • Patent number: 4324295
    Abstract: An agricultural implement is arranged to be connected to a tractor so that it can be pulled over a field covered with organic material, such as live or dead plants or harvesting residues. The implement includes a main support frame followed by an auxiliary support frame. A flail-blade cylinder is dependently supported from the main frame for comminuting the organic material. Arms are mounted on the main frame rearwardly of the cylinder for loosening the soil. On the auxiliary support frame, a device is mounted for breaking up clods of loosened soil. A hood is positioned over the cylinder with a selectively adjustable rear part for directing the flow of the comminuted organic material thrown rearwardly by the cylinder. Other material directing or conveying members can be used in combination with the hood for facilitating the movement of the comminuted material rearwardly from the cylinder.

  • Patent number: 4267891
    Abstract: A cultivating machine has groups of soil working tines that are mounted on an elongated support that is driven to rotate about a horizontal axis. The tines are mounted in spaced apart groups and guide members converge at the rear of the groups to form ridges of worked soil. Each group includes tine units that are formed by opposing bracket portions clamped to the support. Strikers can be mounted on the support between groups of tines and the strikers are pivotable about respective horizontal axes spaced from the support's axis of rotation. The strikers are positioned to excise crop leaves or emerged growth on the ridges. Hoods and a grating ensure that the top layer of worked soil is free of debris. Screening plates having obliquely upwardly and inwardly inclined inner edges are located at the lower, front, outer corners of the hood to prevent the rearwardly adjacent time groups from displacing soil too far laterally.
