To provide the subject device capable of eliminating the need for resetting at the time of restarting operations, instantaneously restarting the operations and improving the operating efficiency by installing a means for storing a specific detected value, storing the detected value before controlling the completion of the operations and returning the posture to that providing the detected value when restarting the operations.

This posture controller is provided with a means for storing detected values of left and right supporting heights and left and right tilt angles, storing the detected values before controlling the completion of operations and returning the posture to that providing the detected values of the left and right supporting heights and left and right tilt angles at the time of restarting the operations in a combine harvester equipped with a pair of left and right lifting and lowering driving means for changing the left and right supporting heights of a machine body, a car height sensor for detecting the left and right supporting heights of the machine body, a horizontal sensor for detecting the left and right tilt angles of the machine body and a controlling means for regulating the machine body to provide the left and right set tilt angles.
