A traction and bending joint for a farm machine using a tractor is provided to minimize the damage of a bending joint when a bending angle is large by letting ends of yokes of both sides have the same angle. A center yoke(11) is installed in the middle of the inside of outer bodies(10,10a) on both sides of a traction and bending joint for a farm machine using a tractor. Yokes(12,12a) on both sides are connected by a cross bearing(13). A power transmission shaft having a spline formed thereon is inserted into insertion holes that form spline on the rear of the yokes on both sides. Springs(21) are installed inside caps(20,20a) between the power transmission shafts and yokes of both sides. A connection rod(31) connecting a pulling rod(30) is attached to the lower part of the outer body of a front yoke with a pin. |
