PURPOSE: To provide the agricultural machinery, which can adjust the braking force of a rear wheel brake to be operated in response to a change of steering angle of a knuckle arm with the simple switching work and which can secure the appropriate automatic braking work at the time of steering even in the case where the upland field condition is different. CONSTITUTION: A joint 17, in which plural groups of adjustment holes 18a, 18b, 18c respectively having a different groove length X1 in the axial direction are drilled opposite to each other, is interposed in a sensor rod 7b connected between a knuckle arm for supporting front wheels and a pair of rear wheel brakes in right and left, and a through hole 18d of the tip of the sensor rod 7b is selectively fitted to any one of the adjustment holes. A screw body is screwed with each right screw lock and left screw lock formed in the inner wall of the joint 17, and the quantity of looseness of the sensor rod 7b in relation to a rod end 6 is controlled for increase and decrease by screwing the screw body, which is coupled with the turning operation of a joint main body 17a, forward and backward. |
