<p>PROBLEM TO BE SOLVED: To provide a manual braking device for braking a rear wheel by braking force larger than an automatic braking device, in addition to the automatic braking device. SOLUTION: A tractor is provided with an automatic braking device 25 for braking a rear wheel at a turning inside by supplying pressure oil to either one of left and right brake cylinders 38, 39 by interlocking with a steering operation for a front wheel at a prescribed steering angle or more and left and right brake switches 42, 43 operated manually. When the brake switches 42, 43 are operated, hydraulic pressure larger than that when the automatic braking device 25 is operated is supplied to the brake cylinders 38, 39 and the rear wheel is braked by large braking force.</p> |
