A hydraulic system including a supply line, an implement-based control valve, an override valve supported by the implement, and a bypass line. The control valve is fluidly coupled to the supply line and configured to regulate a flow of pressurized hydraulic fluid supplied through a downstream actuator line to a hydraulic actuator of the implement. The override valve is fluidly coupled to the actuator line downstream of the control valve and includes a supply position at which the flow of pressurized hydraulic fluid from the control valve passes through the override valve to the hydraulic actuator. The override valve is actuatable to at least one override position at which the flow of pressurized hydraulic fluid from the control valve is cut-off. The bypass line is fluidly coupled between the supply line and the override valve such that a portion of the pressurized hydraulic fluid flows to the hydraulic actuator.

An implement control system includes an automatic control valve assembly configured to utilize fluid from a supply conduit to cause a cylinder to raise a ground engaging tool relative to a soil surface and to utilize the fluid flow from the supply conduit to cause the cylinder to lower the ground engaging tool relative to the soil surface while an automatic control mode is active. The implement control system also includes a controller configured to control the automatic control valve assembly based on a position of the ground engaging tool relative to the soil surface to control the position of the ground engaging tool relative to the soil surface while the automatic control mode is active. The controller is also configured to deactivate the automatic control mode in response to fluid pressure within a first manual control conduit exceeding a threshold pressure.

An agricultural enhancement method for removing or overcoming soil fragipan, hardpan, or other natural and/or artificial soil compaction barriers is disclosed. These barriers prevent root and/or water penetration, which inhibits agricultural development. Consequently, removing and overcoming these barriers is beneficial to the soil and to agricultural yields.

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.

A subsoil tool for ameliorating soil compaction having a shank attached to a toolbar of a tractor, wings on forward wing links pivotally engaged to the shank, and following wings on a wing rod pivotally engaged with the forward wing link. The forward wing links are positioned near the bottom of the shank in front of the rear of the shank. The wing rod is positioned behind the shank. A drive box having a hydraulic cylinder is engaged to the toolbar and pivotally engaged with the wing rod. In use, a portion of the subsoil tool may be inserted below a surface of the soil, the height of the subsoil tool may be adjusted, the subsoil tool may be rotated, and the hydraulic cylinder may be cycled to move the forward wings and following wings.

A depth adjustment assembly for seed planting unit of an agricultural implement may include a cam member rotatable to adjust a vertical position of a wheel of the unit relative to a ground engaging tool of the unit. The cam member may include a first engagement element. The depth adjustment assembly may also include a locking member having a second engagement element and a biasing member configured to bias the cam and locking members together to engage the first and second engagement elements and maintain a rotational position of the cam member relative to the locking member. When the first and second engagement elements are disengaged, the cam member is rotatable relative to the locking member to vary the penetration depth setting.
