The first frame supports a first transaxle apparatus supporting a first axle. The second frame supports a second transaxle apparatus supporting a second axle. Proximal ends of the frames with respect to the vehicle are coupled to each other through a coupling part so that the first and second frames are rotatable relative to each other around a vertical axis according to steering operation. An engine is mounted on the first frame. A first hydraulic motor is integrally assembled in the first transaxle apparatus so as to drive the first axle. A working vehicle is equipped at a distal side of the second frame with respect to the vehicle. A second hydraulic motor is integrally assembled in the second transaxle apparatus so as to drive the second axle. A hydraulic pump is mounted on either the first or second frame, drivingly connected to the engine, and fluidly connected to both the first and second hydraulic motors.

摘要： A hydraulic transaxle including: a variable displacement hydraulic motor with a movable swash plate whose tilt angle defines a displacement of the hydraulic motor; a casing incorporating the hydraulic motor; and a mechanism for determining a range of the tilt angle of the swash plate, wherein the mechanism can fix the tilt angle of the swash plate so as to set the hydraulic motor in a fixed displacement type. A vehicle includes the transaxles for driving respective axles wherein each of the transaxles can select whether the displacement of its hydraulic motor is variable or fixed.
