The purpose of the present invention is to provide a working vehicle with a hydraulic transmission which prevents a port of a valve plate from being corroded by the hydraulic oil that spouts from a groove of the valve plate toward the port in the valve plate. Provided is a working vehicle in which a hydraulic transmission comprising an input shaft operated by receiving the driving force from a driving source, a cylinder block of an input side which rotates with the input shaft integrally, a cylinder block of an output side which rotates by the hydraulic pressure from the cylinder block of the input side, and an output shaft that rotates with the cylinder block of the output side integrally is installed; multiple cylinders are formed in the cylinder block of the input side or at the cylinder block of the output side; a valve plate (86) having a port for hydraulic oil from the cylinder is installed; and multiple grooves (84) are formed in the port, wherein the extension lines of the grooves (84) are crossed in the port. |
