The invention pertains to a corn ear harvester which comprises two deck plates and two gathering chain devices. The gathering chain devices each comprise an endless chain which forms a chain loop which comprises a straight operational part; a corn ear paddle and paddle connector which connects the corn ear paddle to the chain. The device further comprises a corn stalk channel having a deck plate channel section extends between the deck plates and a gathering chain channel section between the gathering chain devices. The deck plate channel section is too narrow for a corn ear to pass through. The corn ear paddles are arranged adjacent to a deck plate on the side of the ear blocking surface of said first deck plate and the endless chains of the gathering chain devices are arranged adjacent to the deck plates on the opposite side.

A combine (12) including a frame (12), power unit (32) and a crop gathering and processing device (18, 20, 24, 26). A grain tank (28) is mounted on the frame (12). An elongated closed end tube (74) is vertically oriented within the grain tank (28) and has a plurality of uniformly spaced openings (76) along its length. A pneumatic pressure supply (86) pressurizes the interior of the tube (74). A pressure sensor (84) senses the interior pressure of the elongated tube (74), so that grain building up therein selectively covers the plurality of openings (76) to cause a proportionate increase in air pressure.

The header (6) comprises a front and rear wheel assembly (11,12), each assembly comprising an axle (13) and two wheels (14a,14b). Each wheel assembly is coupled to the main body of the header (6) by an actuating system (15) comprising an actuator mechanism (40,41) for actuating a swivel movement of the axle (13) and the wheels (14a,14b), to bring the wheel assembly to or from a road transport position. The front and rear wheel assemblies are equipped with tie rod arrangements for steering the header (6) when it is transported on the road. The wheels of the wheel assemblies (11,12) are operated as caster wheels. The tie rod arrangement of the front wheel assembly (11) is coupled to a pivotable base (60) connected to or connectable to a drawbar (55). The wheel assemblies comprise respective actuators (66,68) which are synchronized so as to synchronize the position of the front and rear wheels.

The invention pertains to a harvester header support (20). The harvester header support (20) supports the header during road transport of an agricultural harvester (1) with a header mounted to it in order to reduce the front axle load of the agricultural harvester (1). During harvesting, the support wheel (25) of the harvester header support (20) are folded upwardly so they do not touch the ground during harvesting. The rotation axis (27) of the support wheel (25) extends in a substantially vertical plane during harvesting. This allows for a simple construction of the harvester header support (20) and reduces the vibration loads on the bearing of the support wheel (25) during harvesting.
