Abstract
A hydraulic actuator is arranged such that the hydraulic actuator operates a swash plate of a hydraulic motor by a first pilot pressure and a second pilot pressure, the first pilot pressure being branched from a high-speed oil passage and applied to the hydraulic actuator for operating the swash plate of the hydraulic motor to a low speed side, the second pilot pressure being branched from a charge pump and applied to the hydraulic actuator for operating the swash plate of the hydraulic motor to a high speed side.
