Abstract

An agricultural harvester includes: a harvester frame; an agricultural header coupled with the harvester frame, the agricultural header including a plurality of deck plates; and a control system operatively coupled with the harvester frame and the agricultural header, the control system including: at least one sensor coupled with the agricultural header and configured for: detecting a crop material condition associated with a harvesting operation, the crop material condition being a crop material diameter; outputting a crop material condition signal corresponding to the crop material condition; a controller operatively coupled with the at least one sensor and configured for: receiving the crop material condition signal; determining an operative parameter of the plurality of deck plates based at least in part on the crop material condition signal and at least one offset condition signal.

First claim

What is claimed is:

1 . A control system of an agricultural harvester, the agricultural harvester including a harvester frame and an agricultural header coupled with the harvester frame, the agricultural header including a plurality of deck plates, the control system being operatively coupled with the harvester frame and the agricultural header, the control system comprising:
at least one sensor coupled with the agricultural header that:
detects a crop material condition associated with a harvesting operation, the crop material condition being a crop material diameter;
outputs a crop material condition signal corresponding to the crop material condition; and
a controller operatively coupled with the at least one sensor that:
receives the crop material condition signal;
determines an operative parameter of the plurality of deck plates based at least in part on the crop material condition signal and at least one offset condition signal.

2 . The control system of claim 1 , wherein the controller further for:
outputs an adjustment signal, based at least in part on the operative parameter signal, to an actuator that selectively moves, based at least in part on the adjustment signal, the plurality of deck plates between a first position and a second position.

3 . The control system of claim 2 , wherein the at least one offset condition signal corresponds to a crop material verticality condition.

4 . The control system of claim 2 , wherein the at least one offset condition signal corresponds to a desired amount of a non-grain crop material.

5 . The control system of claim 2 , wherein the at least one offset condition signal corresponds to a crop material variety.

6 . An agricultural harvester, comprising:
a harvester frame; an agricultural header coupled with the harvester frame, the agricultural header including a plurality of deck plates; and a control system operatively coupled with the harvester frame and the agricultural header, the control system including:
at least one sensor coupled with the agricultural header that:
detects a crop material condition associated with a harvesting operation, the crop material condition being a crop material diameter;
outputs a crop material condition signal corresponding to the crop material condition;

a controller operatively coupled with the at least one sensor that:
receives the crop material condition signal;
determines an operative parameter of the plurality of deck plates based at least in part on the crop material condition signal and at least one offset condition signal.

7 . The agricultural harvester of claim 6 , wherein the controller further:
outputs an adjustment signal, based at least in part on the operative parameter signal, to an actuator that selectively moves, based at least in part on the adjustment signal, the plurality of deck plates between a first position and a second position.

8 . The agricultural harvester of claim 7 , wherein the at least one offset condition signal corresponds to a crop material verticality condition.

9 . The agricultural harvester of claim 7 , wherein the at least one offset condition signal corresponds to a desired amount of a non-grain crop material.

10 . The agricultural harvester of claim 7 , wherein the at least one offset condition signal corresponds to a crop material variety.

11 . A method of using an agricultural harvester, the method comprising the steps of:
providing the agricultural harvester including a harvester frame, an agricultural header coupled with the harvester frame, and a control system, the agricultural header including a plurality of deck plates, the control system being operatively coupled with the harvester frame and the agricultural header and including at least one sensor coupled with the agricultural header and a controller operatively coupled with the at least one sensor; detecting, by the at least one sensor, a crop material condition associated with a harvesting operation, the crop material condition being a crop material diameter; outputting, by the at least one sensor, a crop material condition signal corresponding to the crop material condition; receiving, by the controller, the crop material condition signal; and determining, by the controller, an operative parameter of the plurality of deck plates based at least in part on the crop material condition signal and at least one offset condition signal.

12 . The method of claim 11 , wherein the controller is further configured for:
outputting an adjustment signal, based at least in part on the operative parameter signal, to an actuator configured for selectively moving, based at least in part on the adjustment signal, the plurality of deck plates between a first position and a second position.

13 . The method of claim 12 , wherein the at least one offset condition signal corresponds to a crop material verticality condition.

14 . The method of claim 12 , wherein the at least one offset condition signal corresponds to a desired amount of a non-grain crop material.

15 . The method of claim 12 , wherein the at least one offset condition signal corresponds to a crop material variety.
