Claims

[Scope of Claim for Utility Model Registration] A combine harvester having a pre-processing section that is supported in a vertically movable manner, comprising: a lever potentiometer provided on a position control lever for positioning the pre-processing section; a combine main body and the pre-processing section; a lift potentiometer that detects the relative position of the preprocessing section; a position control means that compares the value of the lever potentiometer with the value of the lift potentiometer to control the elevation of the preprocessing section; An ultrasonic sensor is installed to detect the height of the pre-processing section above the ground, and when the cutting height is automatically set, the value of the lever potentiometer is compared with the value from the ultrasonic sensor, and the pre-processing section is A cutting height control device for a combine harvester, comprising: automatic cutting height control means for controlling elevation.
