破損させるといった不具合が生じることがない。As described above, according to the present invention, the position control for controlling the height of the working unit provided on the traveling machine body, the attitude control of the ground working machine, and the like are configured to be controlled by using the microcomputer. In the tractor, a fender that covers the rear wheel of the controller of the microcomputer.
While being located in the space formed by the inner wall and the seat,
A resin cover with an open bottom is arranged above it, and position control operation knobs and posture control operation knobs are centrally provided on the upper surface of this resin cover. Since it is connected to the controller with a harness, there is a possibility that during operation, the controller will be covered with mud or muddy water, or the stones that the rear wheels bounce up will hit and damage the controller. There is no.
