Abstract

A residue management system for an agricultural vehicle includes: a straw hood defining a first rear opening and a second rear opening; a windrow chute held adjacent to the first rear opening; a spreader assembly held adjacent to the second rear opening; a conveyor held within the straw hood and defining a conveyor axis of rotation; and a selection door pivotably coupled to the straw hood and defining a pivot axis which is rearward and below the conveyor axis of rotation, the selection door being configured to switch between a first position in which material from the conveyor is directed toward the first rear opening and a second position in which material from the conveyor is directed toward the second rear opening.

Claims (32)

1. A residue management system for an agricultural vehicle, comprising:

a straw hood defining a first rear opening and a second rear opening;

a windrow chute held adjacent to the first rear opening;

a spreader assembly held adjacent to the second rear opening;

a conveyor held within the straw hood and defining a conveyor axis of rotation;

a first selection door pivotably coupled to the straw hood and defining a pivot axis which is rearward and below the conveyor axis of rotation, the selection door configured to switch between a first position in which material from the conveyor is directed toward the first rear opening and a second position in which material from the conveyor is directed toward the second rear opening; and

a second selection door pivotably coupled to the straw hood, the second selection door pivotable about the pivot axis and defining a first position where the second selection door covers the second rear opening and prevents material flow to the spreader assembly.

2. The residue management system of claim 1 , wherein the selection door at least partially covers the first rear opening in the second position.

3. The residue management system of claim 2 , wherein the selection door completely covers the first rear opening in the second position.

4. The residue management system of claim 1 , wherein the selection door defines a door leading edge held adjacent to the conveyor in the first position.

5. The residue management system of claim 4 , wherein the conveyor is a roller.

6. The residue management system of claim 1 , wherein the spreader assembly includes at least one spreader disc defining a disc axis.

7. The residue management system of claim 6 , wherein the disc axis is one of generally perpendicular to a ground plane and angled with respect to the ground plane.

8. An agricultural vehicle, comprising:

a chassis;

a cleaning system carried by the chassis and including a cleaning fan;

a chopper carried by the chassis; and

a residue management system carried by the chassis rearwardly of the cleaning system and the chopper, the residue management system comprising:

a straw hood defining a first rear opening and a second rear opening;

a windrow chute held adjacent to the first rear opening;

a spreader assembly held adjacent to the second rear opening;

a conveyor held within the straw hood and defining a conveyor axis of rotation; and

a selection door pivotably coupled to the straw hood and defining a pivot axis which is rearward and below the conveyor axis of rotation, the selection door configured to switch between a first position in which material from the conveyor is directed toward the first rear opening and a second position in which material from the conveyor is directed toward the second rear opening.

9. The agricultural vehicle of claim 8 , wherein the selection door at least partially covers the first rear opening in the second position.

10. The agricultural vehicle of claim 9 , wherein the selection door completely covers the first rear opening in the second position.

11. The agricultural vehicle of claim 8 , wherein the selection door defines a door leading edge held adjacent to the conveyor in the first position.

12. The agricultural vehicle of claim 11 , wherein the conveyor is a roller.

13. The agricultural vehicle of claim 8 , wherein the spreader assembly includes at least one spreader disc defining a disc axis.

14. The agricultural vehicle of claim 13 , wherein the disc axis is one of generally perpendicular to a ground plane and angled with respect to the ground plane.

15. The agricultural vehicle of claim 8 , wherein the conveyor is arranged to receive crop material from the chopper.

16. The agricultural vehicle of claim 8 , further comprising a second selection door pivotably coupled to the straw hood.

17. The agricultural vehicle of claim 16 , wherein the second selection door is also pivotable about the pivot axis.
