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).
