PROBLEM TO BE SOLVED: To provide a working vehicle easy in steering, by reducing turning resistance. SOLUTION: A 4-crawler type tractor 1 is constituted by respectively arranging a pair of right-left crawler travel devices 10 and 70 in front and in rear of a machine body, and the front crawler travel device 10 arranged in a machine body front part is constituted so as to be steerable by interlocking with operation of a steering wheel. A crawler width L of the front crawler travel device 10 is formed narrower than a crawler width M of the rear crawler travel device 70, and its longitudinal length is also formed shorter than the longitudinal length of the rear crawler travel device 70. Thus, the front crawler travel device 10 is reduced in the turning resistance, and can easily perform steering operation. COPYRIGHT: (C)2009,JPO&INPIT
