A method for operating an agricultural vehicle. The method including capturing, by the at least one image capturing device, image data of the implement and receive, by the controller, the image data of the implement. The method further includes identifying the implement, by the controller, depending at least in part upon the image data of the implement. The method further includes setting, by the controller, at least one operational parameter of the implement, and managing, by the controller, a turning maneuver of the agricultural vehicle depending at least in part upon the image data of the implement.

A conventional three point hitch of an agricultural tractor for the connection and use of working implements cultivating or excavating the earth and other duties involved in the industry of farming or grading excavation is modified by adding extending and retracting implement-actuators attachable to the existing bottom-lift-arms, therefore supplanting, but still using the existing bottom-lift-arms on the three-point hitch. The implement-actuators assist the implement in correcting the implements centerline when the tractor centerline is off a predetermined centerline path. In addition, the extending of the implement-actuators proportionally, inversely and simultaneously can correct the pivot point of the implement to match the pivot point of the tractor while the tractor performs turns during the working use of the implement.

The present invention enables generating a desired target travel path intended by a user or the like without the need for various input works for the type, width, and the like of a work machine. The present invention is provided with: a travel path generation unit which generates a target travel path (P) along which a work vehicle is caused to travel automatically; and a reference point setting unit which, on the basis of position information about the work vehicle when the work vehicle has been caused to travel, sets a first reference point (A) and a second reference point (B) for generating a first reference line, and a third reference point (C) for setting intervals, wherein the path generation unit generates, as the target travel path (P), a path that includes a plurality of parallel paths (P2) parallel to the first reference line (P1) based on the first reference point (A) and the second reference point (B), and sets respective intervals between the first reference line (P1) and the parallel paths (P2) and also each interval between the parallel paths (P2), on the basis of a distance between the second reference point (B) and the third reference point (C).

In one embodiment, a windrower that comprises: a dual-path steering system configured to drive a pair of drive wheels in an opposite direction of rotation and in a same direction of rotation during non-overlapping time periods; and a steering axle system configured to actively steer a pair of caster wheels while the dual path steering system drives the pair of drive wheels during each of the non-overlapping time periods.

A harvester may include a feeder house, a header mount interface proximate the feeder house; a header removably mounted to the feeder house by the header mount interface, the header having a mount interface for securing the header to a trailer; a sensor to output steering angle signals indicative of a steering angle of the harvester during an approach of the harvester carrying the header towards the trailer, and a controller to output control signals causing the display to overlay a representation of the mount interface on a real-time view of the approach.

An implement for cultivating a field is connected to a self-propelled vehicle that is steered automatically along a first reference path by a steering control unit. The implement is guided in a lateral direction with respect to the vehicle along a second reference path by an implement position control unit by means of an actuator. The steering control unit steam the vehicle in dependence on the position of the actuator at the time.

An implement operating apparatus has a U-shaped drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A power source is connected through a drive control to rotate the drive wheels in either direction. First and second implements are configured to perform implement operations and to rest on the ground and when the drive frame is maneuvered to an implement loading position with respect to each implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a first travel path or a second travel path oriented generally perpendicular to the first travel path.

A vehicle, a tool carriage assembly, and a system are disclosed. The vehicle includes drive wheels and a steering assembly which are responsive to control signal(s) to substantially correct a displacement error of the vehicle relative to an intended travel path. The tool carriage assembly includes a support section operatively mounted to a main body for relative movement. The support section is adapted to have mounted thereto a tool unit comprising a tool head. In response to a displacement error of the tool head relative to the intended travel path, the support section is responsive to one or more control signals to move relative to the main body to substantially correct the displacement error of the tool head. The system includes the vehicle having the tool carriage assembly mounted thereto, and a control system for controlling the correction of the displacement errors of the vehicle and the tool head.

Disclosed are a method and apparatus for determining the heading of a 4WS vehicle. The 4WS vehicle's dynamic pivot point is calculated from the steering angles. A distance between the dynamic pivot point and a Global Navigation Satellite System (GNSS) antenna is determined. A time delay is determined in the form of the distance between the GNSS antenna and the pivot point divided by the current vehicle horizontal velocity. The time delay is multiplied by a vehicle yaw rate to obtain a result which is added to a GNSS antenna heading to give a true heading. A control point for the 4WS vehicle is selected to allow that control point to follow a desired trajectory.

A yaw rate is sensed on a towing vehicle that is towing an air seeder. The sensed yaw rate is used to predict a future yaw rate on a planting implement of the air seeder. An application rate of material is varied across the application implement based upon the predicted yaw rate across the implement.
