A road transport system of a header of a harvesting machine includes two pairs of wheels and two wheel frames. Each wheel frame is connected to a pair of wheels. The two wheel frames are rotatable between a field operation position and a road transport position. A header of a harvesting machine includes two pairs of wheels and two wheel frames. Each wheel frame is connected to a pair of wheels. The two wheel frames are rotatable between a field operation position and a road transport position. A method of converting a header of a harvesting machine from a field operation mode to a road transport mode includes: releasing wheel frames of the header from the header; rotating the wheel frames from a field operation position to a road transport position; and enabling kingpin steering connections between at least one of the wheel frames and a pair of wheels.

A method and system is disclosed for automatic detection of implement working width of an implement on a vehicle. The method includes tracking location of the vehicle; determining if the vehicle is making substantially parallel passes; if the vehicle is making substantially parallel passes the method also includes determining distances between consecutive passes; and calculating a calculated implement working width based on the distances between consecutive passes. A location sensor attached to the vehicle can be used for tracking the vehicle. Determining if the vehicle is making parallel passes can include grouping the location sensor readings into pass lines that each include sensor readings defining a single pass line; and determining if a current pass line is parallel to a prior pass line. Vehicle heading can be used for determining if pass lines are substantially parallel. Known implement working widths can be used to verify calculated implement working widths.

A system for picking up, bundling and depositing agricultural material having a traction vehicle and a towed implement, the system comprising: an actuator associated with the implement; a control device configured to generate control data for controlling the orientation of the implement and steering of the traction vehicle, the control data including information relating to the orientation of the implement adjustable by the actuator, a desired orientation of the deposited agricultural material and at least one of a speed and a direction of travel of the traction vehicle; and wherein, using the control data, the actuator adjusts the orientation about a vertical axis of the implement relative to the traction vehicle to deposit the agricultural material.

A working vehicle includes a traveling body supported by a traveling apparatus, a steeling portion that steers the traveling body, a lifting/lowering apparatus that lifts and lowers a working machine, and a controller configured to execute a turning control of setting a working machine descent start line in a coordinate system having a position of the traveling body at a start of turning as an origin, calculating coordinates of the traveling body based on a steering operation of the steering portion and a traveling distance of the traveling apparatus, and in a case where the traveling body has reached the working machine descent start line in a state in which the traveling body has completed the turning, starting lowering the working machine by the lifting/lowering apparatus.

An agricultural implement has front flotation wheels with a significantly increased diameter, increasing flotation and improving rolling characteristics, especially in soft soil conditions. The implement has a frame supported on front and rear wheels. Front flotation wheels are pivotally mounted to the frame about vertical axes. A hitch tongue is pivotally attached to the frame about a vertical hitch pivot axis. A wheel control mechanism connects the front flotation wheels to the hitch tongue, and is configured such that when the hitch tongue is in a neutral position the front flotation wheels roll in the operating direction, and pivoting the hitch tongue causes the front flotation wheels to pivot in the same direction.

Provided is an accompanying traveling work system in which work is performed by a manned work vehicle that performs pre-process work ahead, and an unmanned first work vehicle that performs post-process work, so that the manned traveling work vehicle can work ahead, and the first work vehicle can performs post-process work while traveling in front of the second work vehicle, wherein the first work vehicle includes a control device that positions a machine body, utilizing a satellite positioning system, and causes the first work vehicle to automatically travel along a set traveling route R, and the first work vehicle traveling diagonally in front includes markers which are landmarks for an advancing direction of the manned work vehicle traveling diagonally behind.
