PURPOSE:To regulate the travel speed by providing a potentiometer for sensing operating position of a manual speed change lever of a combine, etc., and simultaneously providing a push switch for memorizing the operating position of the speed change lever. CONSTITUTION:In a combine equipped with a car speed controlling means (A) for automatically changing the speed according to a load so as to maintain the engine speed constant, a potentiometer 12 for sensing the operating position of a manual speed change lever 7 is installed and a push switch 13 for memorizing the operating position of the speed change lever 7 is simultaneously provided in a gripping part of the aforementioned lever 7. The maximum travel speed produced by operation of the car speed controlling means (A) is regulated to the travel speed when operation is performed with the push switch 13. |
