Intermediate header height on self-propelled windrower for operation at high road speed
An agricultural machine system for moving a header of a self-propelled windrower at road speed. A lift device selectively moves the header between a low position, a high position, and an intermediate position such that the header occupies the intermediate position when the agricultural machine system is in a mode of operation associated with road speed.
1 . An agricultural machine system, comprising:
an agricultural work vehicle including a lift device, wherein the agricultural work vehicle is a self-propelled windrower;
a header coupled with the lift device, the lift device configured for selectively moving the header between a plurality of positions associated with a header height including a low position, a high position, and an intermediate position therebetween such that the header occupies the intermediate position when the agricultural machine system is in a predetermined mode of operation that is associated with a predetermined road speed.
2 . The agricultural machine system of claim 1 , further comprising a control system operatively coupled with the agricultural work vehicle and the header, the control system including:
a sensor configured for:
sensing a header position;
outputting a header position signal corresponding to the header position;
a controller system configured for:
receiving the header position signal;
determining a header adjustment based at least in part on the header position signal, the header adjustment being associated with moving the header to the intermediate position;
outputting a header adjustment signal, based at least in part on the header adjustment, to an actuator configured for adjusting the header position.
3 . The agricultural machine system of claim 2 , wherein the controller system is configured for determining the header adjustment based at least in part on receiving a first signal associated with one of:
(1) a first input directing that the self-propelled windrower be operated in the predetermined mode of operation; and
(2) a second input directing the header to be placed in the intermediate position.
4 . An agricultural work vehicle of an agricultural machine system, wherein the agricultural work vehicle is a self-propelled windrower, the agricultural work vehicle comprising:
a lift device, the agricultural work vehicle configured for being coupled with a header, the lift device being configured for selectively moving the header between a plurality of positions associated with a header height including a low position, a high position, and an intermediate position therebetween such that the header occupies the intermediate position when the agricultural machine system is in a predetermined mode of operation that is associated with a predetermined road speed.
5 . The agricultural work vehicle of claim 4 , wherein a control system of the agricultural machine system is operatively coupled with the agricultural work vehicle and configured for being operatively coupled with the header, the control system including:
a sensor configured for:
sensing a header position;
outputting a header position signal corresponding to the header position;
a controller system configured for:
receiving the header position signal;
determining a header adjustment based at least in part on the header position signal, the header adjustment being associated with moving the header to the intermediate position;
outputting a header adjustment signal, based at least in part on the header adjustment, to an actuator configured for adjusting the header position.
6 . The agricultural work vehicle of claim 5 , wherein the controller system is configured for determining the header adjustment based at least in part on receiving a first signal associated with one of:
(1) a first input directing that the self-propelled windrower be operated in the predetermined mode of operation; and
(2) a second input directing the header to be placed in the intermediate position.
7 . A method of using an agricultural machine system, the method comprising the steps of:
providing an agricultural work vehicle and a header, the agricultural work vehicle including a lift device, the header being coupled with the lift device, wherein the agricultural work vehicle is a self propelled windrower; and
moving selectively, by way of the lift device, the header between a plurality of positions associated with a header height including a low position, a high position, and an intermediate position therebetween such that the header occupies the intermediate position when the agricultural machine system is in a predetermined mode of operation that is associated with a predetermined road speed.
8 . The method of claim 7 , wherein the agricultural machine system further comprises a control system operatively coupled with the agricultural work vehicle and the header, the control system including:
a sensor configured for:
sensing a header position;
outputting a header position signal corresponding to the header position;
a controller system configured for:
receiving the header position signal;
determining a header adjustment based at least in part on the header position signal, the header adjustment being associated with moving the header to the intermediate position;
outputting a header adjustment signal, based at least in part on the header adjustment, to an actuator configured for adjusting the header position.
9 . The method of claim 8 , wherein the controller system is configured for determining the header adjustment based at least in part on receiving a first signal associated with one of:
(1) a first input directing that the self-propelled windrower be operated in the predetermined mode of operation; and
(2) a second input directing the header to be placed in the intermediate position.
