Abstract

A working vehicle with a traversing system wherein a front wheel is installed on a swing member rotatable about a vertical axis relative to a body and including a rotating cylinder for rotating the swing member. The entire part of the front wheel is formed compact in connection with a drivingly running device stored in the swing range of the front wheel. A battery mountable on the body comprises a wide front part movable in the vehicle longitudinal direction between rear wheels in the straight forward running attitude. A narrow rear part is positioned between the rear wheels in the transverse running attitude, whereby the attachment and detachment of the wheel can be preformed easily and can be mounted stably.
