PURPOSE:To make it possible to release reaped lawn from between back wheels backward, preventing clogging of the reaped lawn and improving reaping characteristics, by making driving for running only front wheel and rotation for steering possible. CONSTITUTION:A steering gear is rotated by normal or reverse rotation of a steering motor 5 and front wheels 1 are rotated so as to steer a working vehicle. Therefore a driving equipment for rear wheels 2L and 2R is made unnecessary and part of release guide can be freely constituted and reaping performance is improved without clogging reaped lawn. Further, discharge resistance of the reaping lawn is reduced, since opening of a release guide is enlarged and turning performance of the working vehicle is improved, since the working vehicle is steered and rotated while driving the front wheels.
