A work vehicle includes a touch-panel display, at least one first physical button, and the circuitry. The touch-panel display is to display at least one first touch button, at least one first function, and work information. The at least one function is displayed in the at least one first touch button to which the at least one first function is assigned. The work information includes a state of work which the work vehicle performs. The at least one first physical button is provided outside the touch-panel display. The at least one first function is assigned to the at least one first physical button. The circuitry is configured to change the at least one first function assigned to the at least one first touch button and the at least one first physical button in accordance with the work information.

A steering system is provided for an agricultural vehicle having steerable wheels of a first wheel set, first and second steerable wheels of a second wheel set, and a steering input device configured to receive a manual steering input for the wheels of the first wheel set. The steering system includes first and second hydraulic steering devices coupled to the first and second steerable wheels of the second wheel set; a valve assembly configured to hydraulically control the hydraulic steering devices to steer the wheels of the second wheel set; and a controller configured to determine steering commands and provide the steering commands to the valve assembly. In a rear stability mode, the valve assembly is configured to selectively dampen fluid flow between the first and second hydraulic steering devices.

A travel control system for an agricultural machine capable of performing remotely-manipulated traveling including a storage to store a position of a permitted area in which the remotely-manipulated traveling is permitted conditionally, and a controller operable in a remote manipulation mode in which travel of the agricultural machine is controlled by remote manipulation. In the remote manipulation mode, when a state of the agricultural machine does not satisfy a condition required for the remotely-manipulated traveling in the permitted area, the controller is configured or programmed to disable a remote manipulation to cause the agricultural machine to travel in the permitted area.

An agricultural material baling system comprises, in one example, a bale forming component configured to form a bale of agricultural material from a terrain, and a control system configured to determine that the bale is to be released from the baling system onto the terrain, determine that a current location of the baling system has a slope above a threshold, determine a different location, that is spaced apart from the current location, for releasing the bale onto the terrain, and provide an output indicative of the different location. In one example, the control system is configured to receive yield data indicative of a volume of agricultural material in a path of the baler and to control the baling system based on the yield data. In one example, the yield data is obtained from a raking operation that rakes the agricultural material into a windrow.

A robust system and method for positioning and heading for guidance or logging agricultural input placement amounts and locations is disclosed and can be used to aid or direct treatment of a field that has only partial or temporary access to a reliable GNSS signal. The guidance information or data can be stored in memory and output to a video display terminal or the visual display of a computing unit (e.g. laptop or user mobile phone) or alternative formatted or translated to produce an output on a heads-up display such as a light bar.

A global navigation satellite sensor system (GNSS) and gyroscope control system for vehicle steering control comprising a GNSS receiver and antennas at a fixed spacing to determine a vehicle position, velocity and at least one of a heading angle, a pitch angle and a roll angle based on carrier phase position differences. The system also includes a control system configured to receive the vehicle position, heading, and at least one of roll and pitch, and configured to generate a steering command to a vehicle steering system. The system includes gyroscopes for determining system attitude change with respect to multiple axes for integrating with GNSS-derived positioning information to determine-vehicle position, velocity, rate-of-turn, attitude and other operating characteristics. Relative orientations and attitudes between motive and working components can be determined using optical sensors and cameras. The system can also be used to guide multiple vehicles in relation to each other.

A riding yard maintenance vehicle may include a positioning module. The positioning module may include processing circuitry configured to receive information indicative of vehicle position of the riding yard maintenance vehicle, receive an indication of a triggering event that indicates a presence of an obstacle proximate to the riding yard maintenance vehicle, and cause recordation of an obstacle identifier in association with the vehicle position responsive to receipt of the indication.

Yaw and center-of-rotation of a platform are determined using a single Global Navigation Satellite System (GNSS) device and an inertial measurement unit (IMU). A measurement center of the GNSS device is disposed on the platform away from the center-of-rotation and arranged in a known spatial relationship with the center-of-rotation. The platform is rotated about the center-of-rotation between a first orientation and a second orientation. The IMU is used to determine a change in pitch, roll, and yaw of the platform between the first orientation and the second orientation. The GNSS device is used to determine a change in position of the measurement center of the GNSS device between the first orientation and the second orientation. The yaw of the platform is determined at the second orientation and the position of the center-of-rotation of the platform is determined in a global coordinate frame.

A method for planning a path of a working device includes: generating a polygon corresponding to a work area of the working device and generating an edge data structure based on the polygon; generating a survey area based on the polygon; generating a plurality of survey lines at a predetermined interval in the survey area; detecting at least one intersection between each of edges of the polygon and each of the plurality of survey lines based on the edge data structure; and generating the path of the working device in the work area based on the at least one intersection.

A method is provided for identifying an obstacle during a work operation of a tractor and attached implement combination. The method includes detecting an object during the work operation, and identifying the detected object as an obstacle in dependence on the predefined classification parameter for classification of the detected object or a predefined work parameter of the tractor or the implement.
