御装置。 The lifting control section that controls the lifting operation of the working section includes an upper limit setting control means that sets the upper limit of the working section based on the set position of the set volume, and the lifting control section that automatically raises the working section based on the backward operation of the traveling machine. In the working vehicle, the setting range of the setting volume is divided into two setting ranges in which the same upper limit setting can be made, and the setting range of the setting volume is set in one of the setting ranges in the lifting control section. If the vehicle is within the range, perform reverse climb control,
1. A lifting and lowering control device for a working part in a work vehicle, characterized in that a reverse lifting control switching means is provided for canceling the backward lifting control when the position is within the other setting range.
