To positively operate a traveling apparatus equipped with a round steering wheel and traveling crawlers.

This traveling agricultural apparatus changes the output of an operating HST 16 with the rotation of a round steering wheel 4 and generates a difference between the rotational speeds of right and left traveling crawlers 1a, 1b for steering operation. A traveling mode display part 101 is provided near an operating part 7, which includes a steering status display panel for visibly displaying the rotation operating angle of the steering wheel 4 based on the detected signal of a steering sensor 103, and a traveling status display panel for visibly displaying the rotational speed and rotational direction of each of right and left traveling crawlers based on the detected signals of crawler sensors 104a, 104b.
