An agricultural system comprising a plough. The plough comprising: a plough body; a stone-trip-mechanism that is configured to be tripped when the plough body encounters a stone or other obstruction; and a trip-sensor configured to provide trip-data in response to the stone-trip-mechanism being tripped. The agricultural system also includes a location-determining-system associated with the plough, wherein the location-determining-system is configured to provide location-data that is representative of a location of the plough; and a controller. The controller is configured to: receive the trip-data; and store location-data provided by the location-determining-system as a trip-location based on the trip-data, wherein the trip-location is a location of the plough at the time that the stone-trip-mechanism is tripped.

In one aspect, a system for monitoring the condition of a seedbed within a field may include a seedbed tool configured to ride along a seedbed floor as an implement frame is moved across the field. The system may also include an actuator configured to adjust the position of the seedbed tool along a lateral direction relative to the implement frame such that the seedbed tool traverses a lateral swath of the seedbed floor along the lateral direction. Furthermore, the system may include a seedbed floor sensor configured to detect the position of the seedbed tool relative to the implement frame. The position of the seedbed tool may be indicative of a profile of the lateral swath of the seedbed floor as the seedbed tool rides along the seedbed floor with movement of the implement frame in the forward travel direction.

A tillage implement having a frame member extending in a fore-aft direction of the implement, the frame member pivotally connected in a foldable configuration, the frame member comprising a main frame section; a first wing section and a second wing section, each being pivotally connected at opposing lateral sides of the main frame section in the fore-aft direction; and a middle breaker including a first disc coupled to the main frame section, the first disc laterally offset from a centerline of the middle breaker extending in the fore-aft direction, the first disc having a concave side facing towards the centerline, and a second disc coupled to the main frame section, laterally offset from the centerline of the middle breaker, the second disc having a concave side facing towards the centerline.

A tillage machine includes a main frame, a gang rotatably coupled to the main frame, and an arcuately-shaped adjustment rail coupled to the main frame. At least a portion of the adjustment rail is spaced from the main frame. The adjustment rail includes a plurality of apertures each configured to receive a locking structure, and the adjustment rail defines an open space adjacent the main frame.

A land plane that may be moved over an agricultural field to smooth any irregularities in the surface of the field is pulled by a tow vehicle and has a blade assembly in a general diamond shape. The general diamond shape may be between 30 and 35 feet wide and 35 and 40 feet long. Thus, the land plane may have a sufficient length for drag and earth moving capability to economically and properly level a field, and a sufficient width to cover a substantially large area in single pass over the field. Further, the land plane may have foldable wing sections that enable the land plane to be transported over a typical state or county road or highway.

An implement for an agricultural vehicle including a toolbar and a pair of marking devices pivotally connected to the toolbar. Each marking device includes at least one arm configured for pivoting between a stored position and an operational position, and a retention device supported by the toolbar and configured for providing a magnetic retention force which magnetically retains the at least one arm in the stored position.

A tillage implement is configured to be towed behind an agricultural vehicle. An implement frame has a first lengthwise frame member, a second lengthwise frame member, and a lateral frame member connected to and extending between the first and second lengthwise frame members. A tool assembly is pivotally connected to the implement frame and includes a ground engaging member. An actuator has a first portion connected to the implement frame and a second portion connected to the tool assembly. Movement of the actuator adjusts the position of the tool assembly relative to the implement frame. The lateral frame member includes an actuator opening and at least a portion of the actuator extends into the actuator opening and the lateral frame member.
