An agricultural implement includes a shank assembly having an attachment section and a ground-engaging shank. Furthermore, the agricultural implement includes first and second fasteners coupling the attachment section to a frame member of the agricultural implement. Additionally, the agricultural implement includes a first load sensor configured to generate data indicative of a first load being applied to the first fastener by the shank assembly. Moreover, the agricultural implement includes a second load sensor configured to generate data indicative of a second load being applied to the second fastener by the shank assembly. In addition, the agricultural implement includes a computing system configured to determine when the ground-engaging shank is bent based on the data generated by the first and second load sensors.

An agricultural implement is configured to be advanced in a forward direction and includes an implement frame. The implement frame includes a pair of laterally extending fore-and-aft spaced frame members. The frame also includes a fore-and-aft extending interconnecting member that extends between the frame members and presents forward and aft ends. At least one of the frame members comprises a tubular beam presenting forward and aft walls. The forward and aft walls at least partly define an interior beam space, with a window opening being defined in a first one of the walls. The tubular beam receives a respective end of the interconnecting member so that the interconnecting member extends into and out of the interior beam space through the window opening. The respective end of the interconnecting member is welded to a second one of the walls.

An agricultural tool unit includes a tool configured to engage the ground and a mounting device. The mounting device supports the tool and presents a device opening configured to receive the frame member. The mounting device includes driving and driven cam elements, with the driven cam element defining at least part of the device opening. The mounting device further includes a cam element shifter operable to selectively impart relative shifting of the cam elements in a first direction. The cam elements present respective cam surfaces that are complementally shaped and slidably engaged with one another to define a cam interface, with the cam interface extending transversely to the first direction such that the driven cam element is moved in a transverse second direction when the cam elements are relatively shifted by the cam element shifter. The driven cam element is configured to adjustably exert a force against the frame member when moving in the second direction.

An agricultural implement including a frame configured to be towed behind a vehicle and a plurality of shank assemblies connected to the frame and configured for engaging a soil. Each shank assembly includes a shank mount configured to mount to the frame, a coupling arm pivotally connected to the shank mount and extending rearwardly therefrom, and a shank connected to the coupling arm at an end and extending downwardly therefrom to a tool-supporting end. Each shank assembly also includes a ground-engaging tool connected to the tool-supporting end of the shank and a variable rate spring positioned in between the shank mount and the coupling arm and configured for providing a variable ground-engaging tool load.

A drivable soil working device including a machine frame, a drive, at least one support arm which can be moved up and down by the drive and which is mounted on the machine frame in a pivotal manner, and at least one insertion tool which can be pivoted relative to the support arm about a first pivot axis and which can be moved up and down by means of the support arm. The insertion tool can be inserted into the soil and withdrawn.

A sand bunker rake/infield groomer vehicle having a frame; a plurality of wheels to traverse a driven surface, wherein the wheels are rotatably mounted to the frame; a power source mounted to the frame; and a rear attachment structure attached to the frame, wherein the rear attachment structure provides a joint enabling rotation; a bracket including a shaft wherein the bracket is configured to cooperate with an associated rake/grooming attachment; and a pivoting bracket mounted to the frame.

An agricultural implement includes a shank assembly having a ground-engaging shank. Furthermore, the shank assembly includes a biasing element coupled to a frame of the agricultural implement via a first pivot joint and coupled to the ground-engaging shank via a second pivot joint. Additionally, the agricultural implement includes a load sensor(s) configured to generate data indicative of the load(s) being applied to the first and second pivot joints by the biasing element. In addition, the agricultural implement includes a computing system configured to determine when the ground-engaging shank is tripping or floating based on the data generated by the load sensor(s).

A harrow attachment for a tillage implement includes a harrow drawbar mounting at least one rank of harrowing tools. A pivot link pivotally couples the harrow rank to the drawbar so it can trip by pivoting upward toward the drawbar from a home position in which the harrow rank is farthest away from the drawbar. A downforce spring is coupled to the drawbar and in a variable length state when the harrow rank is tripped to apply a return biasing force to the harrow rank. An adjustment mechanism couples the spring to the harrow rank and/or the pivot link in one of a plurality of adjustment locations in each of which the harrow rank is in the home position and the spring is in a fixed length state in which the biasing force is removed.

An agricultural device associated with reduced tillage techniques in a field includes a frame and a separator supported by the frame. The separator is configured to form a strip of exposed soil in residual plant matter in the field. A crimping device associated with the separator is configured to at least partially crush stems of residual plant matter while maintaining the strip.
