A system for adjusting the spacing between ground engaging tools of an agricultural implement may include a plurality of ground engaging tools including a first end tool, a second end tool, and at least one intermediate tool positioned between the first and second end tools, with an adjustable ground engaging width being defined between the first and second end tools. The system may further include a biasing element positioned between each respective pair of adjacent engaging tools and configured to apply a biasing force against its respective pair of adjacent tools such that an inter-tool spacing between each respective pair of adjacent tools is maintained substantially uniform across the plurality of ground engaging tools as the ground engaging width is adjusted.

A tillage implement, a tillage machine, and a method of tilling soil is provided. The tillage implement includes a mounting bracket that couples to a rolling frame, a shank pivotably coupled to the mounting bracket via a hinge assembly, a soil working tool operatively coupled to a distal end of the shank, and a preload assembly for moving the shank to a loaded position that is rotationally offset from an unloaded position. The tillage machine includes a rolling frame that is pulled by a tow vehicle when tilling a field and multiple ones of the tillage implements operatively coupled to the rolling frame that contact and till the field. And the method includes attaching the tillage implement to a rolling frame, preloading the hinge assembly by moving the shank to a loaded position that is rotationally offset from the unloaded position, and contacting the soil with the soil working tool.

An apparatus for controlling weeds, which includes a tine formation adapted to remove or disrupt targeted weeds, and a tine support assembly adapted to support the tine for movement about a first control axis in a generally vertical direction between an engaged position wherein the tine formation in use contacts a ground surface for removal or disruption of targeted weeds and a disengaged position wherein the tine formation is substantially retracted from the ground surface. The tine support assembly is further adapted to support the tine for movement about a second control axis in a generally horizontal direction. The tine support assembly further includes a first actuation mechanism adapted to effect movement of the tine about the first control axis, and a second actuation mechanism adapted to effect movement of the tine about the second control axis. The apparatus also includes a sensing system for sensing aspects of an environment and generating data indicative thereof, and a classification system for identifying target weeds within the environment on the basis of the data from the sensing system. A control system is adapted to activate the first and second actuation mechanisms of the tine support assembly in accordance with a predetermined control logic thereby sequentially to position the tine for disruptive contact with the targeted weeds.

A jump arm assembly for a tilling machine includes a jump arm and a disc hub assembly. The jump arm has a first end coupled to a frame unit of the tilling machine and a second end opposite the first end. The disc hub assembly includes a an arm end configured to be fixedly secured to the second end of the jump arm, and an opposing disc end. A first plane defined by the arm end of the disc hub assembly is arranged in non-parallel relation with respect to a second plane defined by the disc end of the disc hub assembly.

An apparatus, which may be a tillage apparatus, has a flexible frame. The frame may be made from open members. The frame may support ground engagers and may be supported on wheel assemblies. The ground engagers may be connected to a spring trip mechanism. The ground engagers may be mounted to open members of the frame with a clamping style mechanism. The clamp mechanism may include wedge devices. The frame may be lowered and raised relative to wheels of the wheel assemblies with a lift mechanism. One row of ground engagers may be raised or lowered relative to the frame independent of another row of ground engagers. An anti-skid or skew control system may be employed in association with the independent height adjustment of one row of ground engagers. A system may be provided to maintain and control the height of a tow hitch forming part of the apparatus.

A jump arm assembly for a tilling machine includes a jump arm and a disc hub assembly for coupling a tilling disc to the jump arm. The jump arm has a first end configured to be coupled to a frame unit of the tilling machine and a second end opposite the first end. The disc hub assembly includes a hub housing and a shaft having a first axial shaft section and a second axial shaft section. The first axial shaft section is configured to be rotatably mounted within the hub housing. The second axial shaft section extends outwardly from the hub housing and is at least partially threaded to receive a threaded nut to secure the tilling disc to the disc hub assembly.

In one aspect, a finishing assembly for an agricultural implement may include first and second rolling baskets, a basket support assembly configured to support the first and second rolling baskets relative to each other, a linkage pivotably coupled to the basket support assembly at a pivot point, and at least one damping element. The at least one damping element may be configured to damp pivoting of the basket support assembly about the pivot point in both a first pivot direction and a second pivot direction, the second pivot direction being opposite the first pivot direction.

In the case of a soil cultivation device with multiple harrow tines, the harrow tines are fastened to levers, which are mounted to pivot on tie bars of the supporting frame via carriers. The operating position of the harrow tines is defined by the levers being adjacent to tie bars, and the harrow tines are prestressed into the operating position by springs assigned to them in the form of pneumatic cylinders.

A tilling machine includes a frame having a jump arm frame unit and a plurality of jump arm assemblies supported along a length of the jump arm frame unit such that a lateral gap is defined between each adjacent pair of jump arm assemblies of the plurality of jump arm assemblies. Additionally, the tilling machine includes a plurality of jump arm spacers, with each jump arm spacer being provided in operative association with a clamp unit of a respective jump arm assembly of the plurality of jump arm assemblies to maintain the lateral gap between each adjacent pair of jump arm assemblies.

A jump arm apparatus for a tilling machine includes a jump arm frame unit having a triangular transverse cross-section and a plurality of jump arms assemblies coupled to the jump arm frame unit. Each jump arm unit includes a jump arm having first and second ends, with the first end coupled to be coupled to the jump arm frame unit via a clamp unit and the second end configured to be coupled to a tilling disc.
