Publication number: 20180368318Abstract: A system processes seeds that are present in crop material. The system includes a first shearing surface, a second shearing surface arranged opposite the first shearing surface, and a clearance between the first shearing surface and the second shearing surface. The system passes crop material between the first and second shearing surfaces, where the crop material contacts the shearing surfaces as it passes through the shearing surfaces. Contact with the first and second shearing surfaces damages seeds that are present in the crop material. The system can be installed in an agricultural harvester to damage seeds that are present in crop residue to prevent the seeds from germinating after the crop residue is discharged from the agricultural harvester back into the field.Type: ApplicationFiled: June 21, 2017Publication date: December 27, 2018Inventors: Nathan E.
