Abstract
A wheelbarrow contains a tray, a frame, two legs, two handles, two axle brackets, a wheel axle, and a wheel. The wheelbarrow also contains two spaced apart roll bars extending from the frame in a forward and downward direction to a point forward of the forward edge of the tray, then curving upward and extending vertically for a distance of at least about six inches. The upward curve of the roll bar is located below the wheel axle. The upward curve of the roll bar contacts the ground and forms a fulcrum when the wheelbarrow is raised at an angle of not greater than about 40.degree. and so that the wheelbarrow will balance in a vertical resting position on the vertical extensions of the roll bars if the wheelbarrow is released after being raised at an angle of not greater than about 70.degree..
