An agricultural assistance system includes a route creator to create, on a map representing an agricultural field, a travel route along which an agricultural machine travels, an input to receive input of a turn mode which is one of turn modes differing in terms of how a traveling device of the agricultural machine is driven, a position detector to detect a position of the agricultural machine, an automatic operation controller to perform automatic operation in which the automatic operation controller automatically causes the agricultural machine to travel and automatically steers the agricultural machine, and a turn mode changer to, during automatic operation of the agricultural machine, allow the input to receive input of another turn mode to change the turn mode, and output, to the automatic operation controller, a change command to cause the agricultural machine to turn in the other turn mode inputted via the input.

An agricultural machine includes a traveling vehicle body, a position detector to detect a position of the traveling vehicle body, a lifting device to link a working device to the traveling vehicle body, and an automatic operation controller to perform an automatic operation to cause the traveling vehicle body to travel and cause the working device to perform an agricultural job based on a travel route and the position of the traveling vehicle body. The lifting device is operable to, during the automatic operation, place the working device in a work position in which the working device performs the agricultural job, and the automatic operation controller is operable to cause the lifting device to keep the working device in the work position even after stopping the traveling vehicle body and/or the working device to end the automatic operation at a location short of an unworked area of the agricultural field.

A work vehicle includes a computing system is configured to access a swath line corresponding to a pass to be made across a field by the work vehicle. Furthermore, the computing system is configured to receive the input indicative of an operating parameter of the work vehicle or the associated implement from at least one of a sensor, a user interface, or an associated memory device of the computing system. Additionally, the computing system is configured to determine the operating parameter based on the received input. Moreover, the computing system is configured to adjust a portion of the swath line based on the determined operating parameter prior to making the pass across the field. In addition, the computing system is configured to control an operation of the plurality of components such that the work vehicle travels along the adjusted portion of the swath line.

Additionally, the computing system is configured to determine an operating parameter of the work vehicle as the vehicle travels along the swath line. Moreover, the computing system is configured to adjust a portion of the swath line positioned forward of the work vehicle relative to a direction of travel of the vehicle based on the determined operating parameter as the vehicle travels along the swath line.

A steering system for a towable implement includes a steering sensor, an implement steering controller, a steering control valve, a steering cylinder, and an implement steering mechanism that steers the implement. The steering sensor measures, directly or indirectly, the angular position of the steerable wheels of the implement. The implement steering controller processes feedback from the steering sensor and with a desired steering angle, outputs a steering control signal that is input to the steering control valve. The steering control valve controls the flow of hydraulic fluid to the steering cylinder, which, in turn, powers the implement steering mechanism to turn the wheels of the implement. The steering system may be operated in various control modes, such as, a transportation steering mode, a corner and 180 turn steering mode, a swath tracking steering mode, crab steering mode, and a manual steering mode, which allows manual control of the steering system.

A vehicle for treating an agricultural field includes a weeding-injection unit and a control unit. The weeding-injection unit includes a valve, at least one weeding knife, at least one actuator configured to move the at least one weeding knife, an injection line carried by the at least one weeding knife, and a valve configured to regulate flow of a substance through the injection line. The control unit is configured to identify a plant and control the at least one actuator and the valve to treat the identified plant. Related methods are also disclosed.

Provided is a method of automatically combining a farm vehicle with a work machine including confirming a current position of the work machine, moving a farm vehicle into a range having a predetermined radius around the current position, and controlling the farm vehicle, on the basis of a current position and direction of a first coupling unit included in the work machine, so that the first coupling unit and a second coupling unit included in the farm vehicle are coupled to each other.

A control system for an off-road vehicle configured to traverse an off-road vehicle through a field by determining whether a partial row exist or contour differences exist between opposite edges if a route of traversal is used. If a partial row or a contour difference exist adjust the route to increase overlap of rows of the off-road vehicle to distribute the width of the field evenly among the rows or incrementally adjust each row from a first contour of a first edge to a second contour of a second edge.

An agricultural control system includes a controller comprising a memory and a processor. The controller is configured to determine a first segment of an implement path that enables an agricultural implement to perform an agricultural operation on a first region of an agricultural field. The controller is configured to determine a first segment of a vehicle path of an agricultural vehicle coupled to the agricultural implement based at least in part on the first segment of the implement path to direct the agricultural implement along the first region. The controller is configured to determine a first end-of-row turn of the vehicle path at an end of the first segment of the vehicle path independently of the implement path between the first segment of the implement path and a second segment of the implement path and to output a first signal indicative of the vehicle path.
