Headland grain capture sequence for agricultural vehicle header
A system and method for capturing grain on a header of an agricultural vehicle either before, during or after raising the header in a headland sequence. The header includes (i) a cutter bar, (ii) either an auger or belt positioned adjacent the cutter bar, (iii) a reel positioned at an elevation above the cutter bar, and (iv) a device that is configured to adjust a gap between the reel and the cutter bar. During a harvest mode, the gap is set to a first distance, and, during the headland sequence, the gap is set to a second distance that is less than the first distance. At the second distance, tines on the reel are positioned to sweep crop off the cutter bar toward either the belt or the auger.
1 . A system for capturing grain on a header of an agricultural vehicle before raising the header in a headland sequence, the header including (i) a cutter bar, (ii) either an auger or belt positioned adjacent the cutter bar, and (iii) a reel positioned at an elevation above the cutter bar, said system comprising:
a device that is configured to adjust a gap between the reel and the cutter bar, wherein, during a harvest mode, the gap is set to a first distance, and, during the headland sequence, the gap is set to a second distance that is less than the first distance, wherein, at the second distance, tines on the reel are positioned to sweep crop off the cutter bar toward either the belt or the auger, wherein the device is configured to adjust the cutter bar between a rigid mode and a flex mode, wherein, during the headland sequence, the device is configured to move the cutter bar to the rigid mode before raising the header during the headland sequence; and
a computer that is configured to automatically trigger the device to move the cutter bar to the rigid mode when the agricultural vehicle approaches a headland as sensed by a GPS position of the agricultural vehicle.
2 . The system of claim 1 further comprising the header.
3 . An agricultural vehicle comprising the system of claim 2 .
4 . The system of claim 1 , further comprising a second device configured to move the reel relative to the cutter bar for additionally adjusting the gap between the reel and the cutter bar.
5 . The system of claim 1 , further comprising a third device configured to move the cutter bar relative to the reel for additionally adjusting the gap between the reel and the cutter bar.
6 . The system of claim 1 , further comprising a sensor for either directly or indirectly sensing a distance between the cutter bar and the reel.
7 . The system of claim 6 , further comprising an input device for initiating the headland sequence.
8 . The system of claim 7 , wherein the computer is configured for activating the device based upon signals received from the input device and the sensor.
9 . The system of claim 1 wherein the cutter bar is disposed on an end of a support arm and the support arm is pivotably connected to a frame of the header, and the support arm is prevented from movement relative to the frame of the header when the cutter bar is maintained in the rigid mode.
