Abstract: A system includes an agricultural implement and a tractor for pulling the implement. The implement includes a frame supporting at least one ground-engaging tool and at least one image imager system coupled to a longitudinal end of the frame. The tractor includes a central controller, wherein the at least imager system is operably coupled to the central controller. The central controller is configured to receive image data from an imager system, analyze the image data to identify at least one mark formed in a soil surface, and responsive to identifying the at least one mark, cause feedback regarding a current position and orientation of the implement and an ideal position and orientation of the implement to be output via an input/output device.

Abstract: 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.

Abstract: Described herein are technologies for mapping sensed positions of operative rows of an agricultural implement, such as when the implement moves through a crop field. The technologies include a method including (1) sensing a position of an operative row at a geographic location of the field, (2) matching the location of the field with a position in a map of the field corresponding to the location, and (3) associating the sensed position of the row to the position in the map. In some embodiments, the method includes repeating the aforesaid operations for multiple geographic locations of the field and rendering an image of the map to be displayed in a GUI. Also, in some embodiments, the method includes rendering the image of the map with an image of a yield map of the field. In some embodiments, the method includes generating a topographic map based on the sensed row positions.

Abstract: A tillage implement has a frame with a center section and first and second outer wing sections hingedly attached to respective outer ends of the center section. Controlling a pressure in a secondary side of a hydraulic circuit enables adjustment of the downward pressure precharge provided by hydraulic cylinders based on a desired stiffness of the implement. Flow from a hydraulic supply through a pressure-reducing valve puts the downward pressure precharge on gauge wheels. Once this desired downward pressure precharge has been achieved, flow from the hydraulic supply is shut off and a check valve holds the pressure such that the hydraulic cylinders hold the gauge wheels in the desired position.

Abstract: A method of operating a tillage implement includes providing a map of a field, defining a plurality of boundaries in the map, propelling the tillage implement through the field, and adjusting at least one operating parameter of the tillage implement when the tillage implement crosses a boundary of the plurality. A non-transitory computer-readable storage medium may include instructions that when executed by a computer, cause the computer to propel a tillage implement through a field and adjust at least one operating parameter of the tillage implement when the tillage implement crosses a boundary defined in a map.

Abstract: A tillage implement includes a frame, a first sensor coupled to the frame and configured to measure an orientation of the frame, a shank engaged with the frame and carrying a tilling tool, and a second sensor coupled to the shank or the tilling tool and configured to measure an orientation of the tilling tool. A system for working a field includes a tillage implement and a tractor drawing the tillage implement. The tractor may include a computer configured to receive information from the first sensor and the second sensor and control an operating parameter of the tillage implement. Related methods and computer-readable media are also disclosed.
