Abstract: An agricultural tillage implement including a carriage frame assembly and pull hitch towed by a tractor and forward and aft secondary frames supported by the carriage frame assembly. The forward and aft secondary frames mount gangs of disk blades for tilling the soil. The secondary frames establish a plane and the aft secondary frame is connected to the carriage frame assembly at a greater distance from the plane than the forward secondary frame so that the depth of penetration of the disk blades is uniform during field operation. The tillage implement has outboard wing sections pivotally connected to the secondary frames and annular shims are provided to establish the wing sections and secondary frames in common plane during field operation, the annular shim being rotatable about central axis to present a common surface to the implements irrespective of the orientation of the shims.

Abstract: Apparatus and associated methods for a coulter disk system relate to a lateral actuator module having a programmably positionable control member that is coupled to a gang of coulter disks and is operable to position a control point of the coulter disks at a predetermined position between two opposing, laterally-spaced end-of-travel positions. In an exemplary embodiment, a gang may be mechanically connected to and laterally positioned by the control point. The predetermined position may be, in some examples, dynamically calculated according to a predetermined function and based on information about conditions of the soil in contact with the coulter disks. Various embodiments may dynamically adjust the position of a gang of coulter disks to dynamically and automatically optimize the conditioning effectiveness of the gang of coulter disks in response to parametric information about the soil conditions.

Abstract: The invention refers to a disc (8) for an agricultural implement (1) comprising an annular, outside a predetermined center diameter (D) defined, soil-cultivating portion (44), a central, inside a predetermined center diameter (d) defined, dish-shaped portion (43), with a boss-receiving, inner side and between these portions an existing, annular connection portion (45) with fastening screw holes (46). The connection portion (45) is a truncated conical portion, the inner mantle surface of which is mainly straight or double-bowed with the convex side facing said inner side and a line through the opening plane in the hole opening of each fastening screw hole on said inner side forms an angle ? with a plane that is perpendicular to the center line of the disc, wherein the angle ? is 5°-10°.

Abstract: A soil cultivating apparatus 10 comprises a chassis 14 having an elongate spine 16 carrying support outriggers 18, 20. The support outriggers 18 carry a first disc gang 30. The support outriggers 20 are arranged rearwardly of the support outriggers 18 and carry a second disc gang 40. A soil consolidating roller 38 or a soil consolidating press cultivator 42 is arranged between the first and second disc gangs. In one aspect ground-engaging tines 34 are arranged between the first disc gang and the soil consolidating roller or press cultivator.

Abstract: A method of improving crop residue decay in a field by providing a tillage implement having a frame and a plurality of tillage tool assemblies operably supported by the frame and adjacently spaced therealong, each of the plurality of tillage tool assemblies having first and second rotatable interlocking members, each of the first and second rotatable interlocking members having first and second tillage tools connected thereto arranged in an opposing angular orientation such that the first and second tillage tools of adjacently spaced tillage tool assemblies are angled outwardly toward one another.

Abstract: A tillage implement adapted to be towed by a tractor. The tillage implement having on-the-go angle adjustable disc blades which enables the farmer to vary the amount of crop residue left on the surface of the soil. The implement is comprised of a main frame, a ground wheel assembly operably and pivotally connected to the main frame, a first actuator for pivotally raising and lower the ground wheel assembly with respect to the main frame. The tillage implement further comprising a plurality of disc blade assemblies, the disc blade assemblies arranged as a disc gang. The disc gang being pivotally connected to the main frame such that a second actuator can act to raise and lower the disc gang with respect to the main frame. Each of the disc blade assemblies having first and second disc blades rotatably mounted on disc blade axles fixed to first and second interlocking members.

Abstract: The working depth of obliquely angled disc gangs on the implement can be readily adjusted from the tractor seat with a single hydraulic cylinder through the use of mechanical linkage that couples the hydraulic cylinder with all of the disc gangs for simultaneous movement. Special pivots that join the gangs to the main frame permit the gangs to be manually angled adjusted without affecting depth, and vice-versa, while quick-release locks securely hold the gangs in their selected angular positions yet permit rapid adjustment.

Abstract: An agricultural apparatus having a combination of ground engaging tools thereon. The agricultural apparatus includes a plurality of ground engaging cultivator tools mounted on a frame assembly which is specifically configured to promote accurate lateral spacing of the cultivator tools thereon. The agricultural apparatus further includes a pair of disc gang assemblies arranged on opposite lateral sides of the longitudinal centerline of the implement and a lift mechanism for conjointly elevating and positioning the disc gang assemblies relative to the frame assembly. The frame assembly is comprised of a series of interconnected frame members including laterally extending tool bars. Each cultivator tool is adjustably secured to a respective tool bar by a resiliently biased bracket assembly. To facilitate lateral adjustment of the cultivating tools, the tool bars are fixedly connected in spaced relation to other frame members.

Abstract: A tractor-drawn levee plow having a telescoping frame pivotally supporting a pair of harrow-gangs arranged to move soil laterally toward each other to a center-line to form the levee, the frame also pivotally supporting a pair of hydraulic cylinders powered by the tractor and connected in fluid-power series, one each of which is pivotally connected to the outer end portion of one of the gangs and each of which is utilized in practicing a new method involving forcibly holding the outer portion of its gang in elevated and/or depressed relation to its inner end portion while in ground-engaging position to thereby most effectively and efficiently construct a levee.

Abstract: A tillage system includes forward and rear sets of widely spaced discs and a set of plow points. The discs in the forward set are mounted at spaced intervals so as to leave alternate strips of worked and unworked soil of substantially equal width. Each disc of the rear set is mounted in a strip of soil left unworked by the forward set to complete the working of the top soil. The plow points are located in the furrows of one of the sets of discs (preferably the rear set) to permit some deep plowing. The working depths of the points and discs are independently adjustable. The system is designed for operation at high speed to provide complete coverage of the soil with minimal double working by the discs. It permits deeper penetration by the discs and a controlled amount of deeper plowing by the points while leaving a finished contour which is substantially free of ridges and furrows.

Abstract: A narrow-base terracing plow comprising a tractor-borne transverse frame supporting a pair of transversely spaced rearwardly and outwardly extending gangs of inwardly directed disc harrows, each gang being pivotally mounted on a mounting bracket for vertical swinging movement relative thereto and the mounting bracket being mounted on said frame for swinging movement about a vertical axis, each gang having a rigid link pivotally connected thereto and to the frame and having a hydraulic cylinder extending between its mounting bracket and the medial portions of the gang by means of which the outer end portion of the gang can be forced downwardly into the soil to a greater extent than its innermore portions, thereby causing the soil through which it passes to be moved laterally toward the centerline until a terrace is formed between the gangs and peaks thereat.
