Idle rollers are journaled to the casing between the respective main wheels and the respective driven rollers in a swingable manner. The auxiliary wheels are adapted to freely abut and to be movable away from both the forward and rear driven rollers, respectively, and the respective idle rollers are adapted to freely abut and to be movable away from both the forward or the rear main wheels and the forward or the rear driven rollers, respectively.
