FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machinery industry and can be used in cleaning units of a grain combine harvester. Cleaning of grain combine harvester includes an agitator board with a finger comb mounted on its end, a sieve boot and a fan. The finger comb fingers are pivotally mounted on the agitator board and connected to it by springs. Along the lower side of the fingers gusset plates in the form of a rectangular triangle are attached. The gusset plates are based with the long side on the crossbar which is rigidly attached to side panels of the threshing machine. The direction of the gusset plate location on adjacent fingers is oriented in opposite sides.
