Patent ID: 8758199

Claim:
A work vehicle comprising: an engine; a continuously variable speed change device receiving power from the engine; wheels driven under the power from the continuously variable speed change device; a speed change position sensor detecting a speed change position of the continuously variable speed change device; a speed change operating device setting the speed change position to be requested to the continuously variable speed change device; an operation position sensor detecting an operation position of the speed change operating device; a control device configured to determine a target operation position of the continuously variable speed change device based on a speed change position detection signal from the speed change position sensor, and to output a control signal for correlating the determined target operation position with a current operation position calculated based on the speed change position detection signal from the operation position sensor; and a display device connected to the control device, wherein the control device is configured to set a limit operation position of the continuously variable speed change device based on the current operation position, an actual engine rotation speed and a drop amount of the actual engine rotation speed from a set engine rotation speed; and a limit operation position image is displayed on the display device along with the current position image, the limit operation position image indicating the limit operation position.
