As described above, according to the present invention, the position control for controlling the height of the working portion provided on the traveling machine body,
In an agricultural tractor configured to control attitude control of a ground work machine using a micro computer, the controller of the micro computer is composed of a fender inner wall portion covering a rear wheel and a seat. Since it is a control operation device in an agricultural tractor characterized by being located in a space part covered with a cover, the outside is covered with mud or muddy water or the rear wheel during work. There will be no problems such as rocks hit by and hitting and damaging it. Further, since the controller is provided near the seat and close to a human-operated operation tool such as a knob, wirings can be shortened, and the entire device can be manufactured compactly and at low cost. . Furthermore, since the human-operated tool provided close to the controller is not configured to project to the front part of the fender as in the conventional case, when the operator gets on and off the tractor, The controller can be placed in a very rational position without disturbing.
