PROBLEM TO BE SOLVED: To control the speed ratio of the engine speed to that of a continuously variable transmission mechanism for changing the work speed in an interlocking manner by a single acceleration member, and to appropriately correspond the speed ratio to the working condition. SOLUTION: In this movable agricultural machine to change and control the speed ratio of the continuously variable transmission mechanism 64 to change the work speed based on the actual speed N of the engine 2 to be changed and operated by acceleration members 87 and 94, mode selecting means 95, 114 and 115 to change a plurality of speed ratios of the continuously variable transmission mechanism 64 to the engine speed N are provided, and operation members 95, 114a, and 115a of the mode switching means 95, 114 and 115 are provided in the vicinity of a steering wheel 14.
