PROBLEM TO BE SOLVED: To control the car speed according to a discharging pitch to thereby efficiently perform operation.SOLUTION: There is provided a combine harvester, in which a reaping part for reaping grain culms set upright in a field is mounted in front of the machine equipped with a car-speed controlling means for controlling the car speed and the grain culms reaped with the reaping part are threshed with a threshing part provided in the machine, and designed to bind waste straws after the threshing with a waste straw binding part installed in the machine, and discharge the bundles of the bound waste straws to the outside of the machine. In the combine harvester, the discharging pitch of the bundles of the waste straws bound with the waste straw binding part is detected with a discharging pitch-detecting means so that the car speed is controlled on the basis of the detection results with the car-speed controlling means.COPYRIGHT: (C)2013,JPO&INPIT【課題】放出ピッチに応じて車速を制御することで、効率良く作業を行うこと。【課題を解決するための手段】車速を制御する車速制御手段を備えた本機の前方に、圃場に植立した穀稈を刈り取る刈取部を取り付け、刈取部により刈り取った穀稈を本機に設けた脱穀部により脱穀するとともに、脱穀後の排藁を本機に設けた排藁結束部で結束して、結束した排藁の束を機外に放出するようにしたコンバインにおいて、排藁結束部による結束した排藁の束の放出ピッチを放出ピッチ検出手段により検出して、その検出結果に基づいて車速制御手段により車速を制御するようにした。【選択図】図3
