The second link portion (9, 209 a socket (15). To link adjacent link assemblies (3) or the first link portion (7, 207) to the second link portion (9, 209), the bulbous end (13) is received in the socket (15). In one example, the link assembly (3) is part of an agricultural ground engaging chain (1) having harrow member portions (5). In other examples, the link assembly and system (203) are used to link first element (204) and second elements (206) to one another. This may be used to join or anchor vehicles, structures and the like.

A system for monitoring the levelness of a multi-wing agricultural implement may include a central frame section, a wing section pivotably coupled to the central frame section and a field contour sensor configured to generate data indicative of a contour of an aft portion of the field located rearward of the implement relative to a direction of travel of the implement. The system may further include a controller communicatively coupled to the field contour sensor. The controller may be configured to monitor the data received from the field contour sensor and assess a levelness of the implement based at least in part on the contour of the aft portion of the field.

A system for detecting the operational status of a ground engaging tool of a tillage implement including an agricultural implement including a frame and a tool assembly supported relative to the frame. The ganged tool assembly includes a toolbar coupled to the frame and one or more ground engaging tools coupled to the toolbar. The system further includes a sensor coupled to the tool assembly and configured to capture data indicative of a load acting on the one or more ground engaging tools. Additionally, the system includes a controller configured to monitor the data received from the sensor and compare at least one monitored value associated with the load acting on the ground engaging tool(s). Moreover, the controller is further configured to identify the ground engaging tool(s) as being plugged when the monitored value(s) differs from the predetermined threshold value.

In one aspect, a system for rotationally driving ground engaging tools of an agricultural implement may include a rotational actuator configured to rotationally drive a ground engaging tool of the implement about a rotational axis. A controller may be configured to determine a current ground speed of the implement based on data received from a sensor. Moreover, the controller may be further configured to determine a rotational output for the rotational actuator based on the current ground speed of the implement such that the tool rotates at a predetermined rotational speed relative to soil within a field. In addition, the controller may be configured to control the operation of the rotational actuator such that the actuator provides the determined rotational output to the tool while the tool is disposed at a working position relative to a soil surface of the field.

In one aspect, a system for detecting accumulations of field materials between ground engaging components of an agricultural implement may include first and second ground engaging components configured to rotate relative to soil within a field as the implement is moved across the field. The first and second ground engaging components may be spaced apart from each other along an axial direction of the shaft. The system may also include a sensor configured to detect field materials within a detection zone defined directly between the first and second ground engaging components and above the axis of rotation in a vertical direction of the agricultural implement. Furthermore, the system may include a controller communicatively coupled to the sensor, with the controller configured to determine a parameter associated with an accumulation of the field materials between the first and second ground engaging components based on data received from the sensor.

A tillage implement has a main frame towed in a forward working direction and toolbar assemblies supported on the main frame. Each assembly has an elongate toolbar member transverse to the forward working direction with tillage units spaced along the toolbar member for working the ground. A pivot supports each toolbar at an intermediate location on the toolbar for angular adjustment about an upright axis relative to the main frame. Followers at opposing ends of each toolbar member are received in respective guides at fixed locations on the main frame such that the followers are slidable within the guides in the forward working direction while restricting rotation of the toolbar member about a longitudinal axis of the toolbar member relative to the main frame. Angular position of each toolbar is controlled by an actuator with an attached mechanical indicator that can be read by an operator.

A tillage implement comprising a frame operably supporting tillage tools, and a soil monitoring system comprising instrumentation operably supported from the frame and disposed to detect soil criteria before, after, or before and after the soil is tilled by the tillage tools. The soil criteria detected is at least one of surface residue criteria, soil clod size criteria, and soil shatter criteria.

A ground engagement tool, such as a universal coulter, with an integrated offset to facilitate multiple mounting configurations. In some embodiments, the ground engagement tool includes a polygonal shank, defining, for example, an octagonal or hexagonal cross-section. The polygonal shank enables rotational offset to be secured in discrete rotational orientations. A lower bracket is mounted to a spindle, providing an angular displacement range for angular deflection of the ground engagement tool. The spindle includes a key structure that complements the angular orientations of the polygonal shank so that the lower bracket can be compensated for the rotational offset. A rotational indexing plate enables selection of one of a plurality of angular displacement ranges. Retention rods may be implemented for setting a depth of the tool. A dirt deflector may also be provided, dimensioned to prevent spewing dirt from landing on adjacent plant rows and to prevent fouling in muddy conditions.
