  "textContent": "A hydraulic four-wheel-drive working vehicle 1 includes a hydraulic pump 420, a first hydraulic motor unit 50 having a first hydraulic motor main body 120 and a second hydraulic motor unit 100E having a second hydraulic motor main body 620. A closed circuit a first hydraulic line for sending pressurized fluid discharged from the hydraulic pump 420 to the first hydraulic motor main body 120 at a forward movement of the vehicle, a second hydraulic line for sending pressurized fluid discharged from the first hydraulic motor main body to the second hydraulic motor main body at the forward movement of the vehicle, and a third hydraulic line for sending pressurized fluid discharged from the second hydraulic motor main body 620 to the hydraulic pump 420 at the forward movement of the vehicle. The closed circuit includes a first bypass line 810 that causes at least a part of pressurized fluid in the first hydraulic line to bypass the first hydraulic motor main body to be supplied to the second hydraulic line. The first bypass line 810 has an orifice 820 inserted therein, and preferably has also a check valve 830 inserted therein, the check valve preventing pressurized fluid from being flown from the second hydraulic line to the first hydraulic line.",
