An agricultural toolbar employs at least two wing assemblies for following the contour of the land in a working position and foldable to a transport position for transit on public roads. The principal use in working position benefits from having a wide range of movement to accommodate variations in land contours and soil types. The principal use in transport mode benefits from having a compact configuration to better meet road regulations. End-uses that condition cultivatable land at multiple locations will benefit from the toolbar.

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 agricultural implement comprising: a ground engaging tool; and an actuator mechanism (366; 466; 566). The actuator mechanism is configured to provide a bias force to the ground engaging tool such that it is biased towards a working position. The agricultural implement also includes a controller that is configured to automatically set the level of the bias force that is provided by the actuator mechanism based on control-data.

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 system for remotely controlling hydraulic component of an agricultural implement towed by a work vehicle may include a vehicle-based valve assembly that selectively supplies hydraulic fluid to one or more supply lines of the implement. Specifically, a first supply line may be fluidly coupled to an implement-based valve assembly that regulates the supply of hydraulic fluid to a hydraulic actuator through a first actuator line. A second supply line may be fluidly coupled to the first actuator line downstream of the implement-based valve assembly such that when a user provides a control input at a remote interface, the vehicle-based valve assembly may instead regulate the supply of hydraulic fluid to the actuator. The supply of the hydraulic fluid through the supply lines may additionally be controlled by first and second override valves fluidly coupled to the first and second supply lines, respectively.

A method of controlling the downpressure on an air seeder that has a plurality of seed assemblies and a plurality of fertilizer assemblies each applying an adjustable downforce, wherein the method includes keeping a total downforce applied by all of the plurality of seed assemblies and all of the plurality of fertilizer assemblies less than a maximum downforce. The method may also include keeping the downforce applied by each of the fertilizer assemblies less than the downforce applied by each of the seed assemblies.

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.
