PROBLEM TO BE SOLVED: To provide the subject top sucker designed to be fully packable to its maximum volume so as to enable its capacity to be expanded even in case of limited volume in view of the fact that a conventional top sucker for a grain harvester has been set on the flank of a threshing device, provided with a discharge port integrally, and can be temporarily reserve grains charged via a relevant port through a grain elevator, however, cannot be fully packed because of the presence of an inevitable space even if a charge port is provided on the top side. SOLUTION: This top sucker has such a scheme that the interior thereof is radially divided from the center into a plurality of container chambers, which are made rotatable so as to enable grains to be uniformly and fully packable to a maximum volume each; furthermore, a grain discharge conveyor acts synergistically with a rotatable gutter penetrated through the central part thereof so as to discharge grains via an independently set discharge port into a bag; a power source therefor is designed as two lines, i.e., engine-based and motor-based ones, playing separated roles for grain reserving operation and grain discharging operation.
