における作業部制御装置。[Scope of Claim for Utility Model Registration] A working part is supported on the traveling body via an elevating link so that it can be raised and lowered, and the working part is configured to be able to swing freely in a scale-like manner by a rolling fulcrum shaft. In the paddy field work vehicle, the working part is appropriately controlled to swing by a hydraulic cylinder device, and the working part is swung by an equal rolling amount in one direction and the other direction from an arbitrary extended position of the hydraulic cylinder device. In this case, the cylinder length at any extended position of the hydraulic cylinder device is a,
A working part control device for a paddy field working vehicle, characterized in that, where b is the cylinder length in one direction and c is the cylinder length in the other direction, the following relationship holds true: 1a-b1≈1c-a1.
