PROBLEM TO BE SOLVED: To provide the subject apparatus capable of operability in a small turn by equipping transmission systems to right and left driving rear wheels in a traveling transmission system with clutches, respectively and installing a specific connecting mechanism for clutch operation. SOLUTION: A traveling transmission system to a traveling part is provided with a hydrostatic continuously variable transmission. Each of transmission systems to right and left driving rear wheels 2 in the traveling transmission system is furnished with a clutch 96 for intermitting the transmission. A front wheel steering mechanism ST is equipped with a clutch operation connecting mechanism Z for connecting the clutch 96 so that the clutch 96 at the inner side of rotation is reversely disengaged with a steering operation at a set angle or larger than it from the straight advancement of steering front wheels 1. In the operation, a means provided with only a hand accelerator lever is installed as an accelerator operating means.
