Abstract: A system of folding toolbars on an agricultural implement having a base toolbar, two articulating toolbars, multiple attachments to the toolbar, and a pair of hinges, with each toolbar connected to attachments. The base toolbar is located orthogonally to the direction of travel of the agricultural implement and connected to a hinge at each end, the hinges are each further connected to an articulating toolbar. Each of the toolbars is connected to a set of attachments. Each articulating toolbar rotates about the base on a pivot axis along the direction of travel of the agricultural implement and tilted relative to the ground plane, such that the center of gravity (CG) moves forward in the transport position and a normal force is applied to the articulating toolbars to resist vertical movement when in field position.

Abstract: In lieu of rigid bars, a tillage reel utilizes a number of elongated flexible elements such as lengths of link chain that are spaced circumferentially around the reel and extend axially thereof. The flexible elements bow outwardly by centrifugal force as the reel rolls along the ground during tillage operations to impact and fracture clods encountered at the lower front extremity of the reel. When the reel is used in connection with strip till operations, the flexible elements bow upwardly and inwardly along the lower periphery of the reel as they engage and conform to the transverse cross-section of the strip till berm, thereby avoiding destruction of the berm notwithstanding the clod-pulverizing action provided by the flexible elements.

Abstract: A tillage shank assembly has one or more substance delivery tubes supported along the back edge of the generally upright shank of the assembly. A pair of side plates on opposite sides of the shank have rear margins that project rearwardly beyond the rear edge of the shank to define a protective gap within which the tubes are disposed. Laterally extending projections on the tubes are received within selected ones of a vertical series of holes in the side plates, depending upon the desired depth for the tubes. By temporarily removing a bolt that attaches the tops of the side plates to the shank, the side plates may be separated sufficiently to permit the projections of the tubes to be withdrawn from their current holes and reinserted into other holes to change their vertical locations. Replacing the bolt and tightening it down returns the side plates to their working positions.

Abstract: A one-pass primary tillage machine provides a combination of shallow and deep tillage, residue cutting and mixing, and clod size reduction and leveling of the field to prepare the field for the next planting season. A front group of flat coulters slice through the residue to reduce its size, followed by deep shanks that improve the tilth of the soil to a point below the intended planting depth. Following the shanks, a group of concavo-convex conditioning discs mix the residue with the soil, reduce clod size, and level the field.

Abstract: The implement has a main frame supported at the rear by ground-engaging transport wheels and at the front by ground-engaging gauge wheels. A hitch is pivotally connected to the front end of the main frame so that the hitch and frame can flex relative to one another when the towing tractor experiences different terrain than the main frame. A self-leveling mechanism is normally disengaged when the implement is in its field operating position so that the hitch is free to float relative to the frame during terrain changes. However, when engaged, the self-leveling mechanism operates to maintain the main frame level as the transport wheels are lowered to raise the main frame into its transport position. A latch, remotely actuatable from the tractor seat, determines whether the implement is in its self-leveling mode or floating hitch mode.

Abstract: For use with farm implements having tillage discs, there is provided a disc scraping assembly in which the swingable arm for supporting the scraper blade is provided with a hat section mount together with a compression spring to yieldably hold the blade against the disc. Alternate connections are provided between the arm and the tension means such as to selectively permit use of the assembly in connection with either of a pair of discs depending upon which direction the concave surface of the disc is facing in the implement. The blade is rotatably mounted on the arm through use of a dirt clearance slot which, in turn, releasably receives a pair of yokes freely rotatable on the arm and releasably interlocked with the blade. Removable cross pins in the arm cooperate with the yokes in preventing displacement of the scraper blade axially of the arm.

Abstract: The angular or rotative position of a sprocket wheel may be incrementally adjusted through the appropriate manipulation of a pair of spaced-apart, opposed wedge assemblies mounted on the wheel that capture a crank of the shaft so that by inching the crank in one rotative direction or the other through manipulation of the wedge assemblies, the rotative relationship between the wheel and the shaft is changed. Each wedge assembly includes a pair of relatively shiftable components having interengaging cam surfaces, one of such components having an arcuate surface that is received in slidable, mating engagement by a complementally formed recess on the proximal side of the crank, thereby permitting relative rotational movement between the crank and the wedge assemblies so as to accommodate the swinging or arcuate nature of the crank movement during adjustment.

Abstract: Method for semicontinuous formation of round bales is permitted by positively capturing material introduced into the bale-forming chamber of a round baler after ejection of the last-formed bale and while the web normally defining the chamber remains displaced from its forming position. In one embodiment, the crop-capturing function is performed by a grid comprising a plurality of parallel, upwardly arcuate, elongate bars forwardly mounted on the baler for swinging movement about a transverse axis toward and away from the lower apron of the chamber. Another embodiment employs a rearwardly mounted, vertically swingable grid of parallel, substantially rectilinear, elongate bars to positively retain crop material in the chamber.

Abstract: In a baling operation that uses a continuously reciprocating plunger, if the next charge to be stuffed into the chamber has not yet reached the desired size and density by the time the stuffing fork is ready to begin its next operating cycle, the fork is temporarily deactivated, without affecting the plunger, until the charge reaches full size and density. Thereupon, the fork stuffs the entire charge into the baling chamber in a single cycle of operation for compaction by the plunger. The baler is loaded from the bottom of the baling chamber through an upwardly curved duct that serves both as an accumulating chamber and as a precompression area into which the charge is progressively packed by a rotating, retractable finger drum at the lower end of the duct. A backstop for precompression purposes may be presented at the top of the duct in a number of alternative ways, i.e.

Abstract: A farm implement of the sectional tow type having at least two rigid frames positioned end-to-end and pivotally interconnected, includes a restrictor apparatus for resisting excessive oscillation between the frames and comprises a fixed and a reciprocating bracket having cooperating faces which are urged abuttingly together by a resilient member. The fixed bracket is attached to and disposed upstanding from one of the frames adjacent to the end thereof, and the reciprocating bracket is connected to the other frame by a linkage mechanism having one end pivotally attached to the reciprocating bracket in a spaced relation to the face thereof and having the other end pivotally attached to the other frame in a spaced relation to the pivotal connection. The resilient member is further compressed from a precompressed condition upon pivotal frame motion by the articulate movement of the reciprocating bracket relative to the fixed bracket.

Abstract: A trailing floating mount for agricultural finish tools is connected to the wheeled frame of an implement carriage and includes an elongated, longitudinally oriented finish tool draw bar attached to the carriage by a double-stop bracket which allows the bar freedom to pivot in a vertical plane through an angle sufficient to follow ground contours but limited so that when the implement frame is raised for transport, the draw bar, with the finish tools attached, is also raised but prevented from folding into the implement carriage or tools.
