A swivel wheel wheelbarrow includes a pair of spaced beams that project forwardly from a tray. The wheel is supported by a fork from which a post extends. The lower end of the post is connected to the beams by a lower yoke support, and the upper end of the post is connected to the beams by an upper yoke support. The lower and upper yoke supports are maintained in a stationary position in order to provide optimum support for the wheel. In an alternative embodiment of the invention, a lock is provided for the post. When the lock is engaged, the wheel is locked in a wheel-straight position; when the lock is disengaged, the wheel can pivot freely about the post.
