Abstract

PURPOSE:To prevent abnormal travel, such as pitching, by providing a controller so as to set the travel speed when an operating physical force of a manual operating mechanism is lost by changing over from the manual operating state to an automatic operating state as the upper limit speed. CONSTITUTION:When a threshing load is small in automatic travel control, operating speed is increased to an extremely high speed. Thereby speed change of a speed changer 1 is carried out to a position where an operating physical force of a travel lever 20 is lost in preference to automatic travel control by manual operation of the travel lever 20 and the operating speed is set on the side of a low speed. The side of manual operation is automatically changed over to the side of automatic operation at this set speed and the speed at this time is set as the upper limit speed to perform automatic travel control with a speed sensor 24 and torque sensor. The upper limit speed is automatically memorized by a controller and the upper limit speed in the automatic travel control can be readily changed and set for each operation of the travel lever 20 by manual operation.
