A header including a cutter bar configured to cut crop for harvesting and a header frame supporting the cutter bar. A transport assembly is operatively connected to the header frame. A support arm is rotatably coupled to an axle of the transport assembly and is pivotably coupled to a mounting frame coupled to the header frame. A cam linkage is disposed at the support arm to provide a mechanical advantage for an operator when moving the transport assembly from a transport position to a harvest position. The cam linkage includes a lift assist device having a first end connected to the mounting frame and a second end coupled to a cam arm. Extension of the second end from the first end of the lift assist device applies the cam arm to a cam surface of the support arm to move the transport assembly to the harvest position.

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.

A working vehicle includes a traveling body supported by a traveling apparatus, a steering 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 including setting a working machine descent start line, calculating coordinates of the traveling body based on a steering operation 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.

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 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.

An agricultural planter is configured to be moved over a supporting surface by a vehicle. The agricultural planter includes a frame and a planter assembly coupled to the frame. A first propulsion assembly is coupled to the frame at a first position with the first propulsion assembly having a first traction member configured to engage the supporting surface. A second propulsion assembly is coupled to the frame at a second position with the second propulsion assembly having a second traction member configured to engage the supporting surface.
