A semicrawler-type working vehicle is provided having a vehicle body ( 3 ), a front steering control wheel ( 7 ) arranged at a front side of the vehicle body, a drive shaft ( 26 ) and a pivot shaft ( 22 ) arranged at a rear side of the vehicle body, and a semicrawler unit ( 2 ) driven by the drive shaft. The semicrawler-type working vehicle comprises: a track frame ( 16 ) by which the semicrawler unit ( 2 ) is supported via the pivot shaft ( 22 ) so as to be pivotable relative to the vehicle body ( 3 ); a drive wheel ( 11 ) arranged on the drive shaft ( 26 ); a front driven wheel ( 12 ) and a rear driven wheel ( 13 ) that are supported by the track frame ( 16 ) such that a horizontal distance from the drive wheel ( 11 ) to the front driven wheel ( 12 ) is longer than a horizontal distance from the drive wheel ( 11 ) to the rear driven wheel ( 13 ); and a crawler belt ( 15 ) that is wound around the drive wheel ( 11 ), the front driven wheel ( 12 ), and the rear driven wheel ( 13 ). The pivot shaft ( 22 ) is displaced forward than a vertical line that runs through a center of the drive wheel ( 11 ). |
