PROBLEM TO BE SOLVED: To eliminate a trouble that when a car body is stopped to place each work part in a non-work condition by suspending or ending work, rotation of an engine is automatically slowed down into idling operation, also in the case of stopping a machine body on a sloped land, decreasing of a car height is safe, but smooth car height operation is difficult when idling of the engine is operated before lowering down of this car height, in a combine with the car height up/down controllable and an accelerator controllable for setting an engine speed by a working condition. SOLUTION: This work vehicle, having a car height control device lift controlling a car body in a vertical direction, is provided with a control device detecting each work part for whether in a work condition or non-work condition by a detector to control an engine in an idling condition based on the detection result, and the work vehicle is constituted so as to be controlled in an idling condition after lowering down a car height when it is placed in an up condition even when the engine idling condition in each work part is in a materialized condition.
