The structure has a control device (31) calculating a drop amount of an actual engine rotation speed from a set rotation speed, and setting a limit operation position for a continuously variable speed change device. The control device controls a pump swash plate (31A) such that an operating position of the continuously variable speed change device moves to the limit operating position based on the set limit operating position and information from a swash plate sensor (30), where the control device includes a command unit for commanding a change of correlation data. An independent claim is also included for a method for controlling a speed of a work vehicle.
