Abstract

A method for operating an agricultural vehicle. The method includes an initial step of providing the agricultural vehicle which includes a feeder housing and a header. The header includes at least one row unit, which has a pair of deck plates, and a deck plate adjustment system. The deck plate adjustment system includes at least one actuator connected to the deck plates, an electronic control unit operably connected to the at least one actuator, and at least one sensor. The method includes the further steps of pivoting the feeder housing to raise the header, sending, by the at least one sensor, a signal to the electronic control unit, and cycling the deck plates, by the electronic control unit actuating the at least one actuator to move the deck plates, for removing a buildup of material on the deck plates.

First claim

The invention claimed is:

1. A method for operating an agricultural vehicle, comprising:
providing a feeder housing configured for pivotally connecting to the agricultural vehicle, a header configured for connecting to the feeder housing and moving between a header work position for harvesting a crop material and a header raised position, the header comprising a frame and at least one row unit connected to the frame, the at least one row unit comprising a pair of deck plates moveably connected to the frame, the deck plates of the at least one row unit being separated from one another by a gap, and a deck plate adjustment system comprising at least one actuator connected to the deck plates, an electronic control unit operably connected to the at least one actuator, and at least one sensor connected to one of the feeder housing and the header and operably connected to the electronic control unit;
pivoting the feeder housing to raise the header to the header raised position;
sending, by the at least one sensor, a signal to the electronic control unit upon raising the header to the header raised position; and
cycling the deck plates while the header is in the header raised position, by the electronic control unit actuating the at least one actuator to move the deck plates, upon receiving the signal from the at least one sensor for removing a buildup of material on the deck plates, the cycling comprising opening the deck plates to widen the gap between the deck plates and closing the deck plates to narrow the gap between the deck plates.

2. The method of claim 1 , wherein the deck plates are positionable in a deck plate operating position and cycling the deck plates further comprises resetting the deck plates to the deck plate operating position.

3. The method of claim 2 , wherein cycling the deck plates comprises:
opening the deck plates to a maximum open position, closing the deck plates to a maximum closed position, and resetting the deck plates to the operating position.

4. The method of claim 2 , further comprising a step of pivoting the feeder housing to lower the header to the header work position, and the sequential steps of pivoting the feeder housing to raise the header and pivoting the feeder housing to lower the header define an end-of-row-turning cycle of the header.

5. The method of claim 4 , wherein cycling the deck plates comprises:
opening the deck plates and resetting the deck plates in a first end-of-row-turning cycle of the header; and
closing the deck plates and resetting the deck plates in a second end-of-row-turning cycle of the header.

6. The method of claim 4 , wherein the step of cycling the deck plates is implemented upon a tenth end-of-row-turning cycle of the header.

7. The method of claim 1 , wherein the at least one sensor is in the form of a potentiometer connected to the feeder housing.

8. The method of claim 1 , wherein the at least one sensor is in the form of a header height sensor that is connected to the header.

9. The method of claim 1 , wherein the at least one actuator comprises a pair of actuators, and each actuator is respectively connected to each deck plate.

10. An agricultural vehicle, comprising:
a chassis;
a feeder housing pivotally connected to the chassis;
a header connected to the feeder housing and configured for moving between a header work position for harvesting a crop material and a header raised position, the header comprising:
a frame; and
at least one row unit connected to the frame, the at least one row unit comprising a pair of deck plates moveably connected to and supported by the frame and separated from one another by a gap; and

a deck plate adjustment system comprising:
at least one actuator connected to the deck plates;
an electronic control unit operably connected to the at least one actuator; and
at least one sensor connected to one of the feeder housing and the header and operably connected to the electronic control unit, the at least one sensor being configured for sending a signal to the electronic control unit upon the header being in the header raised position, wherein the electronic control unit cycles the deck plates while the header is in the header raised position, by actuating the at least one actuator to move the deck plates, upon receiving the signal from the at least one sensor for removing a buildup of material on the deck plates, the electronic control unit cycles the deck plates so the deck plates open to widen the gap between the deck plates and close so the deck plates narrow the gap between the deck plates.

11. The agricultural vehicle of claim 10 , wherein the deck plates are positionable in a deck plate operating position and the electronic control unit cycles the deck plates to:
reset the deck plates to the deck plate operating position.

12. The agricultural vehicle of claim 11 , wherein the electronic control unit cycles the deck plates to open the deck plates to a maximum open position, close the deck plates to a maximum closed position, and reset the deck plates to the operating position.

13. The agricultural vehicle of claim 11 , wherein the feeder housing is configured for pivoting to raise the header to the header raised position and pivoting to lower the header to the header work position such that the sequential pivoting of the feeder housing to raise and lower the header defines an end-of-row-turning cycle of the header.

14. The agricultural vehicle of claim 13 , wherein the electronic control unit cycles the deck plates to:
open the deck plates and reset the deck plates in a first end-of-row-turning cycle of the header; and
close the deck plates and reset the deck plates in a second end-of-row-turning cycle of the header.

15. The agricultural vehicle of claim 13 , wherein the electronic control unit cycles the deck plates upon a tenth end-of-row-turning cycle of the header.

16. The agricultural vehicle of claim 10 , wherein the at least one sensor is in the form of a potentiometer connected to the feeder housing.

17. The agricultural vehicle of claim 10 , wherein the at least one sensor is in the form of a header height sensor that is connected to the header.

18. The agricultural vehicle of claim 10 , wherein the at least one actuator comprises a pair of actuators, and each actuator is respectively connected to each deck plate.

19. A header for an agricultural vehicle, the header being configured for moving between a header work position for harvesting a crop material and a header raised position, the header comprising:
a frame;
at least one row unit connected to the frame, the at least one row unit comprising a pair of deck plates moveably connected to and supported by the frame and separated from one another by a gap; and
a deck plate adjustment system comprising:
at least one actuator connected to the deck plates;
an electronic control unit operably connected to the at least one actuator; and
at least one sensor operably connected to the electronic control unit, the at least one sensor being configured for sending a signal to the electronic control unit upon the header being in the header raised position, wherein the electronic control unit cycles the deck plates while the header is in the header raised position, by actuating the at least one actuator to move the deck plates, upon receiving the signal from the at least one sensor for removing a buildup of material on the deck plates, the electronic control unit cycles the deck plates so the deck plates open to widen the gap between the deck plates and close so the
