GRAIN CULMS-CONVEYING APPARATUS OF COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To provide a grain culms-conveying apparatus of a combine harvester with which reaping operation can be continued even when the field is an ill- drained paddy field in which a crawler traveling device sinks. SOLUTION: In this grain culms-conveying apparatus of the combine harvester, a controller is equipped with a lift-raising switch 91 for starting the rise of a pre-treating part of the combine harvester and a potentiometer 21 for detecting a position of the pre-treating part, and the controller controls so as to stop conveyance of grain culms of the pre-treating part when the pre- treating part rises continuously by a predetermined height from a rise-starting position. Thereby, conveyance of grain culms in the pre-treating part can accurately be controlled without being influenced by the conditions of the field.
