Abstract

5 divided areas of the threshing cylinder were made and the threshing torque and threshing performance where the cylinder had various specifications in every each area were predicted by comparison with the standard specification from the result of the indoor test. Several combinations of cylinder specifications were selected where the torque was less consumed within the allowable threshing loss. These specifications have a point in common where the threshing teeth are decreased in the front part of cylinder and the load in this part is made to reduce. And the threshing torque was to reduce more in case that the screw height gradually increased from top to end of the cylinder. The cylinders which had selected by calculation were tested in practical harvesting with the normal range of speed for the actual proof.
