An agricultural implement includes a plurality of ground-engaging tools configured to modify a surface configuration of an agricultural field and a hydraulically-controlled subsystem configured to modify an operating angle of the plurality of ground-engaging tools. The agricultural implement also includes a sensor coupled to the hydraulically-controlled subsystem configured to generate sensor signals indicative of a current operating angle of the plurality of ground-engaging tools. The agricultural implement also includes an implement control system configured to receive the sensor signals from the sensor to determine the current operating angle of the plurality of ground-engaging tools, and, upon determining the current operating angle is to be changed to a new operating angle, generate control signals for the hydraulically-controlled subsystem to modify the operating angle of the plurality of ground-engaging tools from the current operating angle to the new operating angle.

A link assembly (3) for an agricultural ground engaging chain (1) including a plurality of link assemblies, the link assembly including: a first component (7) having a first clamping portion (21) and a first link portion (13) for linking with a link portion of an adjacent link assembly; a second component (9) having a second clamping portion (27) and a second link portion (15) for linking with a link portion of an adjacent link assembly; a harrow member (5) has a first side (17) and an opposite second side (19); at least one resilient spring plate (22) wherein the resilient spring plate is elastically deformable, and at least one fastening element (11). The resilient spring plate urges the first and second components (7, 9) to retain the components of the link assembly together.

A ground engaging agricultural blade, coulter, or disc having a central opening adapted to be attached to an implement for rotation about a substantially horizontal axis of rotation; the coulter or disc have an outer periphery; and plurality of step plane notches disposed in the outer periphery. The blade can be used with a hub disposed around the central opening or a spacer spool on a shaft extending through the central openings of adjacent blades, the spacer spools extending radially outwardly by a distance.

A system for adjusting the alignment of ground engaging tools of an agricultural implement may include a first toolbar configured to support a first plurality of tools aligned along a first tool axis, and a second toolbar configured to support a second plurality of tools aligned along a second tool axis. The second toolbar may be movable relative to the first toolbar between a first toolbar position and a second toolbar position such that the second tool axis is movable relative to the first tool axis. The system may additionally include an actuator configured to actuate the second toolbar between the first toolbar position, where the first and second tool axes are substantially coincident, and the second toolbar position, where the second tool axis is substantially spaced apart from the first tool axis.
