A grain harvester for propulsion by a tractor over a field of grain growing on upwardly extending plant stems, the harvester having a housing supported and movable in a direction of travel over a field of grain by a tractor, an elongated cylindrical brush supported by the housing and rotating about a horizontal axis that is transverse to the housing direction of travel, the brush having bristles extending generally radially therefrom, shield members supported by the housing in planes parallel the brush rotational axis, the shield members providing an elongated air and grain intake opening, an air discharge opening and a grain discharge opening, the openings being spaced apart from each other, a grain bin supported by the harvester housing and connected with the grain discharge opening, the brush being rotated as the harvester is moved to draw air and grain into the housing through the air and grain intake opening and to dispel grain through the grain discharge opening into the grain bin, and to dispel air out the air outlet opening, the air outlet opening providing greater air velocity flow through the housing to more effectively gather and collect grain for deposit in the grain bin.
