ABSTRACT:
A hydraulic driving vehicle comprises front and rear transaxles incorporating respective hydraulic motors, and a pump unit separated from the front and rear transaxles. The pump unit incorporates a hydraulic pump having a pump shaft. A hydraulic circuit is formed by piping between the pump unit and the front and rear transaxles so as to circulate hydraulic fluid between the hydraulic pump and the hydraulic motors. A reservoir tank of the hydraulic fluid is connected to the hydraulic circuit by piping. A first cooling fan blowing air away from the pump unit and a second cooling fan blowing air toward the pump unit are disposed oppositely to each other with respect to the pump unit and drivingly connected to the pump shaft. At least a pipe for the piping of the hydraulic circuit and the reservoir tank passes an area blown by each of the first and second cooling fans.
