    摘要: A working vehicle comprising two pumps for driving hydraulic motors provided for opposite running devices individually and a valve mechanism for bringing the vehicle into a low-speed state wherein a fluid is supplied from the pumps to the motors individually, or alternatively into a high-speed state wherein the combined fluid from the pumps is supplied to the motors in series. The vehicle is provided with an operating assembly for preventing the vehicle from turning at a high speed even when the vehicle is inadvertently so operated by the driver in the high-speed state.
