A tillage implement has a frame with a center section and first and second outer wing sections hingedly attached the center section such that the wing sections can be operably raised and lowered between a field-working position and a transport position. The sections each carry tillage tools for working the soil. Controlling a precharge in a secondary side of a hydraulic circuit enables the operator of the implement to adjust the downward pressure precharge provided by a plurality of hydraulic cylinders based on a desired stiffness of the implement. A pressure-reducing valve is configured such that flow from the hydraulic supply applies downward pressure precharge on the plurality of tillage tools. Once this desired precharge has been achieved, flow from the hydraulic supply is shut off and a check valve holds the pressure such that the plurality of hydraulic cylinders holds the tillage tools in position.

Systems and methods provide automatic assignment of control of a plurality of hydraulic circuits of an associated work vehicle to a plurality of operation systems of an implement. A hydraulic circuit assignment control unit includes a processor, a memory device, logic stored in the memory device, and a communication circuit operatively coupled with the processor. The processor executes the logic to associate an activation of a first hydraulic circuit of the plurality of hydraulic circuits of the associated work vehicle with a physical exercise of an operation system of the plurality of operation systems of the associated implement, and generates pairing assignment data representative of the association of the activated first hydraulic circuit with the physical exercise of the operation system of the implement. The logic generates directionality confirmation and calibration data that is communicated to the plurality of operation systems with the pairing assignment data.

An agricultural implement includes a main frame assembly, a toolbar coupled to the main frame assembly, and a wing wheel linkage assembly coupled to the toolbar. The agricultural implement also includes a wing wheel rotatably coupled to the wing wheel linkage assembly. In addition, the agricultural implement includes an actuator coupled to the wing wheel linkage assembly and configured to drive the wing wheel linkage assembly to move the wing wheel linkage assembly substantially along a vertical axis between a planting position and a headland position.

The present invention relates to an agricultural implement comprising a main frame supporting a plurality of ground engaging tools, the main frame being transferable between a first configuration, in which a first plurality of ground engaging tools are in a working position, and a second configuration, in which a second plurality of ground engaging tools are in a working position. A first depth wheel is connected to the main frame and capable of adjusting a working depth of the first plurality of ground engaging tools, when the main frame is in its first configuration. A second depth wheel connected to the main frame and capable of adjusting a working depth of the second plurality of ground engaging tools, when the main frame is in its second configuration. At least the first depth wheel is pivotable in such a way that the first depth wheel moves with respect to the second depth wheel.
