記載の圃場作業機における傾斜自動制御装置。[Claims for Utility Model Registration] (1) In a field working machine in which a working part is attached to a traveling body via an elevating link mechanism, the traveling body has a non-contact grounding device that detects the distance from the field. A pair of left and right detection sensors are provided, and the control unit that inputs the detection values from these ground detection sensors and outputs the necessary control commands to the actuator that controls tilt control compares the detection values from both ground detection sensors. What is claimed is: 1. An automatic tilt control device for a field work machine, characterized in that a tilt control determining means is provided for determining a tilt control command and outputting a tilt control command based on the difference between the detected values. (2) Automatic tilt control in a field working machine according to claim 1, wherein the ground detection sensor is installed to detect a field scene in front of the ground contact position of the front wheels. Device.
