A combine harvester which has an axial flow type thresher with a screw requires more power than a tangential flow type one because the crops are managed for longer second in the threshing part. A tendency to equip a higher powered engine with this type of combine harvesters has been seen lately. However on the other hand it is necessary to reduce the required power by means of reexamination in the specification of the threshing cylinder, while maintaining the threshing performance. The object of this study is to find out the specification where the required power will be less consumed. The first part of this study describes to develop the detector in order to measure the forces on the some parts of the thresher, to inspect its function and to understand the distinctive features of the loads in the threshing parts of the combine harvester.
