徴とするトラクタのドラフトコントロール装置。 The top link mounting member, which is supported by the machine body so that it can rotate forward and backward, is connected to the hydraulic control device, and the top link mounting member senses the compressive force applied to the top link due to an increase in the traction resistance of the work equipment, and switches the hydraulic control device. In the draft control device for a tractor, which is operated to raise a working machine, the top link mounting member is rotatably supported in the longitudinal direction with respect to a bracket fixed to the machine body via a bracket fixing bolt, and the top link is mounted. A stopper for restricting forward rotation of the top link mounting member is suspended between the member and the bracket so as to be swingable left and right and slidable in the longitudinal direction via a stopper bolt provided above and outwardly than the bracket fixing bolt. A tractor characterized in that the stopper is configured such that when the stopper is placed on one side of the bracket fixing bolt, the stopper is held in an operative state, and when it is placed on the other side, the stopper is held in an inactive state. draft control device.
