え装置。[Scope of Claim for Utility Model Registration] (1) In a working vehicle provided with a control unit that controls the working depth based on the detection result of a working depth detection sensor, the working unit has a control unit that controls the speed of the working unit. Provided is a transformation speed switching mechanism that switches the transformation speed of the working part by determining whether it is on the upper or lower side with respect to the position set by the position setting means,
The transformation speed is configured to be changed to a low speed when the working part transformation is performed below the switching position and to a high speed when the transformation is performed above the switching position, and the transformation speed switching position setting means is configured to switch the transformation speed. What is claimed is: 1. A control speed switching device for a working section in a working vehicle, characterized in that it includes an adjusting tool that can variably adjust its position. (2) The control speed switching device for a working part in a working traveling vehicle as set forth in claim 1, wherein the transformation of the working part is vertical movement control. (3) The control speed switching device for a working part in a working traveling vehicle according to claim 1, wherein the changing shape of the working part is a left/right tilt control.
