。This is a mobile agricultural machine in which the left and right traveling devices 4.4 are independently moved up and down relative to the machine body by hydraulic cylinders 7.7, and the hydraulic cylinders 7.7 are manually operated to switch between three positions. The hydraulic cylinder 7.7 is connected in parallel to the valve 8 and configured to be driven synchronously in the same direction.
is also connected to a three-position switching type control valve 10 that operates based on the detection results of a left-right tilt sensor 11 attached to the fuselage 3, so that the fuselage 3 can be maintained in a horizontal horizontal position.
a state in which the hydraulic cylinder 7.7 is configured to be automatically controlled, and the operation of both the hydraulic cylinders 7.7 is controlled only by manual operation of the three-position switching valve 8; and the control valve 10.
A mobile agricultural machine characterized in that it is provided with a two-position switching valve 9 for switching a hydraulic path between a state in which it is automatically controlled only by .
