<P>PROBLEM TO BE SOLVED: To provide a four-crawler type vehicle preventing the scattering of mud to a machine-body side. Ž<P>SOLUTION: In the four-crawler type tractor 1, an upper part of a drive sprocket which is a top portion of a front portion crawler traveling device 10 is covered along its crawler shape, and mounted to a knuckle arm 45 steering the front portion crawler traveling device 10 by a bolt 60. A front portion fender 36 moves, together with the front portion crawler traveling device 10 so as not to change the relative position, when the front portion crawler traveling device 10 is steered to move in a lateral direction, and has a clearance capable of preventing interference, even if the front portion crawler traveling device 10 vertically rocks to a maximum extent.
