A system for monitoring the condition of a seedbed within a field may include an implement having a plurality of ground-engaging tools supported by the frame, with the implement being configured to create or be traversed across a seedbed extending downwardly within the field from an outer seedbed surface to a seedbed floor. The system may also include an auxiliary support arm coupled to a portion of the frame at or adjacent to the aft end of the frame. In addition, the system may include a seedbed floor detection assembly coupled to the auxiliary support arm that is configured to detect variations in a profile of the seedbed floor. Moreover, the system may include a seedbed surface detection assembly coupled to the auxiliary support arm that is configured to detect variations in a profile of the outer seedbed surface.

An agricultural tillage implement including a first frame configured to be moved in a travel direction, at least one second frame coupled with the first frame, at least one rolling basket assembly coupled to the at least one second frame, at least one actuator pivotally connected to the at least one second frame, and a pressure control system operatively connected to the at least one rolling basket assembly. The pressure control system includes at least one sensor coupled to the at least one rolling basket assembly for sensing a load exerted on the at least one rolling basket assembly by a ground surface and providing a downward pressure measurement signal. The pressure control system also includes a controller in communication with the at least one sensor and configured to control the adjustable downward force applied by the at least one actuator.

By providing a hydraulic system for configuring an angle of rotation for smoothing tools of a harrow that is predetermined for a tilling session, hydraulic pressure of the hydraulic system may be maintained (and not adjusted) to allow the hydraulic system to actuate during the tilling session by tilling forces encountered by the smoothing tools. As a result, the angle of the smoothing took may change during the tilling session, thereby allowing excessive plant residue encountered by the smoothing tools to be passed over to minimize plugging or bunching.

A harrow implement comprises a tool bar and harrow sections extending rearward therefrom. Each of a plurality of hydraulic cylinders is connected between the tool bar and a corresponding harrow section. A hydraulic control is operative to supply pressurized hydraulic fluid such that the hydraulic cylinders exert a substantially constant selected bias force on the harrow sections. The hydraulic control is operative to direct pressurized hydraulic fluid into a first port on each hydraulic cylinder to exert a downward bias force on the plurality of harrow sections, and operative to direct pressurized hydraulic fluid into a second port on each hydraulic cylinder to exert an upward bias force on the plurality of harrow sections. The hydraulic cylinder can be configured to raise the harrow sections to an idle position above the ground, and to a transport position extending up from the tool bar.
