Claims

[Scope of utility model registration request]

Each track frame in a pair of left and right traveling devices is configured to be independently raised and lowered relative to a machine frame disposed below a traveling machine body equipped with a threshing section, and the mowing height is adjusted at the front of the traveling machine body. The reaping pre-processing device is configured to be raised and lowered via a hydraulic cylinder, the rear end of the traveling machine is pivotally connected to the machine frame so as to be vertically movable, and the traveling machine is raised and lowered back and forth with respect to the machine frame. The pre-reaping treatment device is equipped with a ground height sensor, the traveling body is provided with a left-right tilt sensor, and a front-rear tilt sensor, and the reaping pre-treatment device is adjusted up and down based on the detection results of the ground height sensor. The attitude control device for a combine harvester is characterized in that it gives top priority to the control of the vehicle, then controls the longitudinal inclination of the traveling machine based on the detection results of the left and right inclination sensors, and further controls the elevation and descent of the left and right track frames based on the detection results of the longitudinal inclination sensors.
