WORKING VEHICLE

Provided is a working vehicle capable of, while reducing fuel consumption, improving traveling performance only when high traveling performance is required. A wheel loader comprises: an engine ; a variable displacement HST pump ; a variable displacement HST motor connected to the HST pump through a closed circuit; pressure sensors A, B configured to load pressure of the HST motor ; and a controller , wherein the controller is configured to, in a case of determining that a load pressure detection value P is included in a predetermined pressure range of greater than load pressure Pa corresponding to flat ground traveling and smaller than load pressure Pγ corresponding to an excavation operation, increase maximum rotational speed of the engine only within the predetermined pressure range.
