Abstract: Scarifier for deep strip-tillage, that after a single trip allows the soil to be in adequate conditions for planting or sowing, operating with a great energy efficiency, contributing to an improvement in the production environment. The scarifier comprises a plurality of tillage units (a), spaced apart and located parallel to each other, and wherein each tillage unit (a) comprises a support structure (2) on which the corresponding tines (1a, 1b, 1c) are mounted, the lower ends of which are located at different heights, with the depth below the ground (d) being greater toward the rear of the scarifier. The scarifier preferably incorporates a fertilization system.

Abstract: A drawbar apparatus for coupling an earth-working tool to a frame of an agricultural implement. The drawbar apparatus comprises a drawbar. The drawbar is pivotally coupled to the frame. A first bracket comprises a first portion and a second portion. The second portion is pivotally coupled to the drawbar. A second bracket comprises a first portion and a second portion. The second portion is pivotally coupled to the drawbar. A tool support is coupled to the first portion of the first bracket and the first portion of the second bracket. The tool support is configured to fold relative to the drawbar.

Abstract: A seabed plow capable of over-the-stern release and retrieval is usable in any of boulder clearing, trench cutting and backfill modes. In its boulder clearing mode, the plow uses its skid in torquing configuration followed by moldboards to push boulders out of the path to be trenched. In the trench cutting mode, the plow uses the skid in the same configuration with its share and moldboards for initial trench depth and the same share and moldboards with moldboard extensions for increasing trench depth in subsequent passes. In the backfill mode, the plow uses its skid in trench-straddling configuration following a blade with a passage designed to discharge fragmented spoil directly onto the pipe being covered. Thus, a single plow can be reconfigured for all modes for release and retrieval to and from a relatively small vessel without use of heavy lifting equipment.

Abstract: An agricultural implement includes a tool bar assembly configured to couple to a main frame of the agricultural implement and a pull frame. The tool bar assembly includes a first tool with a height that is adjustable relative to a soil surface. The pull frame includes a hitch assembly configured to be coupled to a work vehicle, a mounting portion configured to be removably coupled to the main frame of the agricultural implement, and a hollow portion that extends over the first tool bar between the hitch assembly and the mounting portion while the tool bar assembly and the pull frame are coupled to the main frame. The hollow portion is configured to accommodate one or more conduits.

Abstract: A tool bar mounting assembly for an agricultural implement. One agricultural implement includes a first tool bar assembly having a tool bar and a plurality of row units coupled to the tool bar and configured to deliver flowable agricultural product to a field. The agricultural implement also includes a frame assembly coupled to the first tool bar assembly. The frame assembly includes a mounting assembly having a mechanical linkage. The mechanical linkage is configured to removably couple the first tool bar assembly to the frame assembly via a plurality of fasteners. The frame assembly is configured to provide structural support to the first tool bar assembly. The mechanical linkage of mounting assembly is configured to removably couple a second tool bar assembly having a different configuration than the first tool bar assembly to the frame assembly via the plurality of fasteners.

Abstract: A mount for carrying a plurality of field-conditioning implements selected from trash whipping implements, rolling baskets and coulters for connection to a planter or other multi-row implement is disclosed. A height and force adjustable mounting system is also disclosed that enables the force of such an implement on the soil to be modulated as desired.

Abstract: The combination of a rolling basket tillage implement and a seed distribution implement is disclosed. A height-adjustable mounting system for a rolling basket soil tillage implement is also disclosed for use with a planter that enables such an implement to be raised above the soil as needed to avoid wet conditions.

Abstract: A knife assembly includes a unique finned point with angled soil-engaging surfaces defining several fracture areas and preventing slabbing to avoid excessive soil disturbance and knife wear. The knife has an extended length between the point and upper mounting brackets to facilitate operation of the point over a substantial range of depths, and the mounting brackets operate above ground level even at maximum point depth operation.

Abstract: An implement for preparing seed beds and lawns, and for grading tracks and show rings, includes a main frame upon which scarifying teeth are mounted to penetrate and scarify the soil, tines which work the soil and prepare the final grade, and a blade for grading soil. The frame is supported on wheels, and attached to a tractor by a three-point hitch. Accordingly, the depth of penetration of the scarifying teeth and the angle at which the tines work the soil, may be adjusted by pivoting the implement about the axis defined by the axles of the wheels by using the tractor hydraulic system. Since this degree of adjustment is limited, the wheels are mounted to the frame by an adaptor plate including multiple openings, any of which the axle of a wheel to thereby adjust the height of the frame relative to the ground to accommodate both loose or hard soil.

Abstract: A ground working device formed of a frame having a lower surface, and plural individually retractable teeth secured to the frame and extending away from the surface in a ground contacting array. Teeth for the ground working device are formed as part of a retractable tooth assembly. A retractable tooth assembly preferably comprises a tooth carrier on one end of which a tooth is slidably mounted, and on the other end of which is mounted a tooth position fixative, with a position adjustable rigid link connecting the tooth position fixative and the tooth. The retractable tooth assembly preferably extends through the frame from a first side to a second side, the retractable tooth assembly being secured to the frame on the first side and the tooth forming a working end on the second side.

Abstract: A blade plow preferably formed by three frame sections hingedly coupled together includes a ground or terrain contour following mechanism within each frame section. The contour mechanism allows the middle blade to be raised and lowered to maintain the entire central blade horizontal relative to the plow frame and at a constant depth within the ground. Additional "fixed" blades are hydraulically setable for depth of cut. The terrain contour following mechanism allows for larger frame widths without the usual tendency of smaller width frames to buckle due to ground unevenness.

Abstract: A cultivating implement has side-by-side soil working members journalled in a hollow frame portion. Each member includes a support with hub that is connected to the lower end of a corresponding shaft. The shafts of the soil working members have meshed pinions on their upper ends that are housed in an upper chamber of the frame portion. The support and hub are housed substantially in their entireties within the frame portion and the lower side of each hub has apertured tags with pins that comprise quick release fastenings for downwardly extending tines.
