Additionally, the system may include a controller communicatively coupled to the first and second rotational speed sensors, with the controller being configured to identify a levelness state of at least a portion of the agricultural implement based at least in part on the rotational speeds of the first and second tools.

A device for processing the soil comprises a frame which carries at least one processing tool and at least one resilient element which has a first end portion which is associated with the processing tool and a second end portion which is associated with the frame by means of connection devices. The connection devices comprise a first laminar element which is arranged in an upper position with respect to the second end portion of the resilient element and a second laminar element which is arranged in a lower position with respect to the second end portion. The connection devices further comprise a separator device which is arranged between the first laminar element and the second laminar element which is capable of forming a separation between the second end portion and the laminar elements which defines a cavity between the first laminar element and the second laminar element, inside which the resilient element can bend.

An agricultural tilling assembly has an elongate structure, and at least one ground engaging tool sub-assembly. The sub-assembly includes a hub having a mounting portion, a ground engaging tool securable to the hub or integrally formed therewith, and a weight having a body with an open aperture having a mouth, the mouth configured for enabling the weight plate to be threaded over the elongate structure so that the elongate structure extends through the aperture, and the open aperture configured so that the weight plate is maneuverable over a portion of a length of the hub whilst in situ on the elongate structure and to be beatable on the mounting portion. The ground engaging tool is connectable to a respective one of the hubs of the tilling assembly whilst that hub is retained interconnected in situ on the tilling assembly, and without removing another ground engaging tool from the tilling assembly.

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.

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.
