An agricultural apparatus includes a first main wing and at least one wheel on one side and a second main wing and at least one wheel on an opposite side. The first and second main wings are pivotable about respective axes of rotation between extended positions in which the first and second main wings extend laterally outward from respective opposite sides of the frame structure, and retracted, storage positions in which the first and second main wings extend generally along a length of the frame structure for shipping or transport. The first and second main wings include respective raised sections each configured to extend over a respective wheel on a corresponding side of the frame structure in the storage position. The raised sections each include a frame having a generally concave shape receiving a portion of one of the first and second wheels in the storage position.

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.

A system for detecting plugging of ground-engaging tools of agricultural implements includes an aft sensor(s) configured to capture data indicative of a post-worked residue coverage of a portion of a field aft of a ground-engaging tool(s). The system includes a controller configured to monitor the data received from the aft sensor(s) and determine the post-worked residue coverage for the portion of the field. The controller is configured to identify when the ground-engaging tool(s) is experiencing a plugged condition based at least in part on the determined post-worked residue coverage for the field.

A cultivating disc for a tillage implement includes an attachment portion positioned at a radial center of the cultivating disc. The attachment portion includes one or more attachment features configured to couple the cultivating disc to the tillage implement about an axis of rotation of the cultivating disc. The attachment portion extends along a first plane perpendicular to the axis of rotation of the cultivating disc. The cultivating disc also includes a cutting edge portion positioned at a distal end of the cultivating disc relative to the axis of rotation. The cutting edge portion extends along a second plane parallel to the first plane. The cultivating disc further includes a curved connecting portion positioned between and connecting the attachment portion to the cutting edge portion. The curved connecting portion further defines one or more radii of curvature.

A system for identifying plugging within an agricultural implement is provided. The system includes a ground engaging tool configured to be supported by the agricultural implement. A weight sensor is operable to measure a weight of one or both of the ground engaging tool and the agricultural implement. A controller is communicatively coupled to the weight sensor. The controller is configured to receive, from the weight sensor, a signal that corresponds to the weight of one or both of the ground engaging tool and the agricultural implement. The controller is further configured to determine when the ground engaging tool is plugged based at least in part on the signal from the weight sensor.

A system for monitoring the levelness of an agricultural implement may include first and second tools rotatably supported on the agricultural implement, with the first and second tools being spaced apart from each other in at least one of a longitudinal direction or a lateral direction of the agricultural implement. The system may further include a first rotational speed sensor configured to detect a rotational speed of the first tool and a second rotational speed sensor configured to detect a rotational speed of the second tool. 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 sowing coulter arrangement comprises a suspension device for mounting the sowing coulter arrangement on a machine frame; a coulter frame connected to the suspension device for mounting components of the sowing coulter arrangement thereon; and a coulter disk. The arrangement further comprises a furrow closer pivotally mounted on the coulter frame; a metering device for dispensing the material to be distributed; a seed tube for transporting the material to be distributed from the metering device to a seed furrow; and a catching element for catching the material disposed downstream of the outlet of the seed tube. The metering device, the seed tube, and the catching element form a unit and are mounted on a carrier that is pivotably affixed to the coulter frame, whereby an arrangement of an outlet of a seed tube in relation to a catching element is at all times kept largely constant.

The invention relates to a soil-working device having an overload protection means, in the case of which overload protection means rebound energy is reduced after the soil-working device returns from an overload position to the working position.

A disk for use with a tillage machine includes a body portion rotatable about an axis of rotation. The body portion has a circumferential edge and a concavity with a first radius defined from a point on the axis of rotation. A hub portion is continuous with the body portion and presents an abutment face having a concavity with a second radius defined from a point on the axis of rotation. An aperture extends through the abutment face and is centered about the axis of rotation.
