A work vehicle includes travelling work state detection sensors to detect a travelling work state of the work vehicle to output detected signals indicating the traveling work state. Circuitry is configured to determine that an early abnormality occurs when the detected signals satisfy a first condition, the work vehicle being in an early stage of trouble in travelling due to the early abnormality. The circuitry is configured to determine that an actual abnormality occurs when the detected signals satisfy a second condition which has a second threshold severer than a first threshold of the first condition, the work vehicle being in trouble in travelling due to the actual abnormality. The circuitry is configured to provides notifications of the early abnormality and the actual abnormality toward an outside of the work vehicle when it is determined that the early abnormality and the actual abnormality occurs, respectively.

A steering system for a work vehicle includes a steering hand pump, a hydraulic main supply line fluidly coupled with the steering hand pump and including a check valve, and a normally open, two position valve. The valve includes an inlet fluidly couplable with a pressurized access point of a hydraulic sub-system, an outlet fluidly coupled with the main supply line on a downstream side of the check valve, and a pilot port fluidly coupled with the main supply line on an upstream side of the check valve. The valve is operable in the closed position based on pressure in the main supply line when the main supply line is pressurized from a pressure source, and operable in the open position and interconnecting the pressurized access point with the main supply line through the outlet when the main supply line is not pressurized from the pressure source.

The method comprises associating a steering characteristic with a respective parameter set of a plurality of predetermined parameter sets. Detecting an instantaneous working condition of the agricultural tractor by a control unit. Selecting a parameter set from the plurality of predetermined parameter sets based on the detected instantaneous working condition; and activating an actuating device based on the selected parameter set to adapt a steering characteristic to the detected instantaneous working condition.

A control method is provided for agricultural or industrial operating machine having a drive unit provided with elements that allow autonomous movement of the machine and a tool couplable to the drive unit by connection and support elements. The method includes storing data characterizing the type of tool and its technical features in an RFID unit; stably arranging the RFID unit on the tool; prearranging, on the machine, a unit for reading the RFID unit; connecting the tool to the machine; automatically establishing a short-range wireless connection between the reading unit and the RFID unit to recognize a correct coupling of the tool and send data characterizing the type of tool installed and its technical features towards the reading unit; and setting up settings of operating units of the machine based on the values of the characterizing data. The operating units provide mechanical or hydraulic power to actuate moving parts of the tool.

A method for operating a hydrostatic steering device for an agricultural utility vehicle, includes controlling a steering orbitrol of the hydrostatic steering device by a steering wheel via a steering column, deflecting a steering cylinder in accordance with a driver-side steering actuation of the steering wheel, detecting a steering actuation variable via a first sensor, detecting a steering position variable via a second sensor, in a normal operating mode, the control unit is configured to actuate the electric drive unit such that an actuating torque which increases continuously with the wheel steering angle is generated at the steering column and thus at the steering wheel, and in an emergency operating mode, the control unit is configured to control the electric drive unit such that an actuating torque is generated on the steering column and thus on the steering orbitrol to support driver-side steering actuation.

The present invention provides an improved mechanism for centering implements in agricultural fields by providing a laser guidance system with a laser attached to the implement. The laser may operate to emit a beam in order to produce a spot or beam onto the field which an equipment operator may visually target to improve steering of the implement. The laser may be centered on the implement, and the beam produced by the laser may be directed forward within a steering range of the implement and within a field of view of the equipment operator.

A method for controlling an agricultural vehicle includes receiving, via a processor, a first signal from a user interface indicative of a value of at least one parameter. The method also includes determining, via the processor, a path of the agricultural vehicle toward a guidance swath based at least in part on the at least one parameter. In addition, the method includes outputting, via the processor, a second signal to a display of the user interface indicative of instructions to present a graphical representation of the path of the agricultural vehicle. Furthermore, the method includes controlling the agricultural vehicle, via the processor, based at least in part on the at least one parameter upon receiving at least a third signal from the user interface indicative of acceptance of the value of the at least one parameter.

An operation management system for a vehicle controllable by an operator to perform various vehicle actions, the system including a processor, a memory, and a human-machine interface. The processor is configured to record sequences of operator-initiated vehicle actions into the memory, record a distance value associated with each vehicle action relative to a previous vehicle action in the sequence into the memory, and generate a new sequence in the memory beginning with each vehicle action.

System and techniques for an image filter based on row identification are described herein. A crop row center represented in an image of a crop row can be calculated. A filter corresponding to a set of expected crop characteristics of the crop row can be obtained. Elements in the image can then be categorized based on applying the filter to the image when the filter anchored on the crop row.
