Reversible compression auger on harvesting header

A system for reversing a rotational direction of an auger of a header of an agricultural machine, said system comprising:

• a first fluid line for delivering fluid to a motor that is configured to drive the auger;
• a directional flow control valve connected to the first fluid line and movable between (i) a first state in which the directional flow control valve is configured to deliver the fluid to the motor in a first fluid direction to cause the motor to move the auger in a first rotational direction, and (ii) a second state in which the directional flow control valve is configured to deliver the fluid to the motor in a second fluid direction that is different from the first fluid direction to cause the motor to move the auger in a second rotational direction that is opposite to the first rotational direction;
• a pump connected to the first fluid line for delivering fluid to the directional flow control valve;
• two flow control valves positioned in series in the first fluid line between the pump and the directional flow control valve, wherein a first flow control valve of the two flow control valves is positioned downstream of a second flow control valve of the two flow control valves, and wherein the two flow control valves are configured to be operated together to deliver a constant flow rate to the motor;
• and
• a second fluid line connected to (i) the first fluid line at a location between the two flow control valves and (ii) an input of the first flow control valve for communicating the fluid pressure in the first fluid line to the first flow control valve,
• wherein the directional flow control valve is maintained in the first state during a harvesting operation, and the directional flow control valve is maintained in the second state during an operation to dislodge crop material from the auger.
