Abstract: Systems and apparatuses for detecting an amount of steering articulation of a steering system are disclosed. The systems and apparatuses may be applied to steering systems of agricultural header transport systems. The systems and apparatuses may include a first component moveable with a first steering component and a second component that is movable with a second steering component. The first component and the second component may interact to generate a notification that a selected amount of steering articulation has occurred or is about to occur. The notification may be provided to an operator, such as in the form of a visual, audible, or haptic output.

Abstract: A transport assembly for a harvesting head that includes head connector arms, a transport axle, and a coupling system with a latch actuator, and first and second latch mechanisms coupled to the latch actuator and located at opposite ends of the transport axle. The transport assembly functions in working and transport modes. In the working mode, the first and second latch mechanisms latch the first and second head connector arms to the transport axle to latch the harvesting head to the transport axle. When the latch actuator is activated, the first and second latch mechanisms release the first and second head connector arms from the transport axle to allow the harvesting head to separate from the transport axle. When the latch actuator is not activated, the first and second latch mechanisms can be biased to remain latched.

Abstract: A steering system for an agricultural machine includes a first and second wheel assembly. Each wheel assembly includes an axle assembly including an axle, wheels rotatably connected to the axle, and a double-action hydraulic cylinder. In some embodiments, the double-action hydraulic cylinder is configured to pivot the wheels in either direction to indicate a direction of turn. In some embodiments, the double-action hydraulic cylinder of the first wheel assembly is hydraulically linked in its operation to an operation of the double-action hydraulic cylinder of the second wheel assembly.

Abstract: 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.

Abstract: A harvesting head for an agricultural harvester including a center frame section that is pivotally coupled to each of a left frame section and a right frame section. The elevation or height of the center frame section is determined by setting a height of the inner gauge wheels of the left and right frame sections. A gauge assembly for each of the left and right frame sections includes a linking member that spans between and operatively connects to outer and inner gauge wheels. The gauge assemblies are operably connected to the left and right frame sections to adjust an elevation of the outer and inner gauge wheels relative to the linking member to thereby adjust the elevation or height of the frame section when actuated by an actuation mechanism.
