The present invention relates to a plough implement comprising a main frame supporting a plurality of first ground engaging tools, wherein the plough implement comprises a depth adjustment apparatus for moving a first ground engaging tool of the plurality of first ground engaging tools with respect to the main frame to enable adjustment of a working depth of the first ground engaging tool.

A tillage implement for variable tillage has a linkage mechanism disposed longitudinally between two gangs of annular harrow tools, the gangs each having a toolbar that is rotationally mounted on a frame of the implement. The linkage mechanism has a plurality of pivotally connected linkage arms, the toolbars each pivotally connected to at least one of the linkage arms. Operation of the linkage mechanism simultaneously rotates one toolbar about a first vertical rotation axis and the other toolbar about a second vertical rotation axis in an opposite rotational direction as the first toolbar. The implement has at least one wheel mounted on the frame longitudinally forward of both of the gangs or longitudinally rearward of both of the gangs. The tillage implement provides variable tillage while having a shorter frame to facilitate folding wing sections of the frame in a more compact manner for transportation while remaining assembled.

A spacing adjustment mechanism of a depth gauge wheel assembly of a planting row unit of an agricultural implement includes a rod fixed on one side to a pivot assembly of the planting row unit, and on which a spindle with a threaded external face is mounted, the threaded external face interacts with a threaded inner face of a bearing of a support arm of a gauge wheel.

System that automates crop maintenance activities, such as cultivating and weeding, with a device that intelligently and independently controls two blades that drag along either side of a crop row using sensors to repeatedly track the position of the blades and of the plants in the row. Blades may be moved in and out independently using an actuator for each blade to contour closely around the individual plants, even if plants or rows vary in their positions, and even if plant sizes and shapes differ. An illustrative system may use a single camera and a processor per crop row; the processor may analyze camera images to locate plant positions and shapes, to plan blade trajectories, and to control blade actuators. The processor may be able to control blade movement precisely to respond quickly to sensor input on changes in plant positions, shapes, and sizes along the row.

A tillage implement comprising a main frame, a front group of coulter blades carried by the main frame and extending generally laterally, and a rear group of coulter blades carried by the main frame and extending generally laterally. The tillage implement additionally comprises a set of wheels configured to support the main frame and positioned generally between the front and rear groups of coulter blades. The tillage implement additionally comprises a group of harrow assemblies carried by the main frame and positioned rearward of the rear group of coulter blades. The tillage implement additionally comprises a front group of finishing reels carried by the main frame, extending generally laterally, and positioned rearward of the group of harrow assemblies. Furthermore, the tillage implement comprises a rear group of finishing reels carried by the main frame, extending generally laterally, and positioned rearward of the front group of finishing reels.

In one aspect, a system for controlling the operation of a seed-planting implement may include a furrow-forming tool configured to form a furrow in soil present within a field. Furthermore, the system may include a sensor configured to capture data indicative of a topographical profile of the soil within the field. Additionally, a controller of the disclosed system may be configured to identify a topographical feature within the field based on the data received from the sensor. Furthermore, the controller may be configured to determine a position of the furrow-forming tool relative to the identified topographical feature. Additionally, the controller may be configured to initiate a control action to adjust the position of the furrow-forming tool when it is determined that the relative position between the furrow-forming tool and the identified topographical feature is offset from a predetermined positional relationship defined for the furrow-forming tool.

The present invention relates to a method for operating an attachment arranged on a pick-up apparatus of a self-propelled combine harvester, wherein the attachment comprises a central portion and two side portions which are each connected to the central portion by a frame joint so as to be pivotable about a pivot axis oriented in the direction of travel, wherein the respective side portion is pivotable about the pivot axis transversely to the direction of travel relative to the central portion by means of an actuator that is activated by a control apparatus, wherein a vertical distance of the attachment from the ground is adaptively set by at least one hydraulic cylinder on the pick-up apparatus, wherein, for the ground guidance of the attachment, the positioning of the side portions relative to the central portion is controlled or regulated independently of vertical and transverse guidance, activated by the combine harvester, of the attachment.

An agricultural implement comprising: a ground engaging tool; and an actuator mechanism (366; 466; 566). The actuator mechanism is configured to provide a bias force to the ground engaging tool such that it is biased towards a working position. The agricultural implement also includes a controller that is configured to automatically set the level of the bias force that is provided by the actuator mechanism based on control-data.

The present invention relates to a plough implement comprising a main frame supporting a plurality of first ground engaging tools, wherein the plough implement comprises a depth adjustment apparatus for moving a first ground engaging tool of the plurality of first ground engaging tools with respect to the main frame to enable adjustment of a working depth of the first ground engaging tool.
