ABSTRACT A mechanical harvester developed and tested in Woodward County, Oklahoma shows great potential for harvesting seed of certain chaffy-seeded grasses. Airflow around the upward rotating brush pulls seed heads into the brush where seed are removed by flailing action and are propelled into the seed bin. Seed harvesting trials on Old World bluestems were conducted using three brushes of different designs that all harvested seed efficiently at 1000 rpm. The fine diameter-high density bristle brush required more revolutions per meter of travel to be as effective as the coarser diameter-lower density bristle brushes(Download PDF) (Export to EndNotes)
