ーにおけるクイツクターン装置。 In a four-wheel drive tractor, the double-acting hydraulic cylinder tilts the front axle vertically, which is rotatably supported around the center of the shaft, and when the handle is rotated beyond the rotation angle during normal steering. In addition to providing a directional switching valve that operates to switch the pressure oil flow path, each of the telescoping hydraulic action chambers on both sides of the double-acting hydraulic cylinder is connected to each hydraulic brake device of the left and right front wheels, and the steering wheel is rotated during normal steering. The hydraulic circuit is constructed in such a way that when the front axle rotates in the direction of the turn by more than an angle, the front axle rotates downward on the inside of the turn and upwards on the outside of the turn, and a brake is applied to the front wheel on the outside of the turn. Features a quick turn device on four-wheel drive tractors.
